Description
Dispositivo para el montaje y desmontaje de una válvula de bola.Device for mounting and dismounting a ball valve.
La presente invención está relacionada con las válvulas de bola tipo "TOP ENTRY", proponiendo un dispositivo destinado para realizar el desplazamiento en separación de los asientos de dichas válvulas a efectos de dejar el espacio libre necesario para el montaje y desmontaje de los elementos componentes internos de las mismas.The present invention is related to "TOP ENTRY" type ball valves, proposing a device intended to perform the displacement in separation of the seats of said valves in order to leave free space necessary for the assembly and disassembly of the component elements internal of them.
Las válvulas de bola tipo "TOP ENTRY" comprenden una bola atravesada por un orificio, la cual se dispone en el interior de un cuerpo, de forma que mediante el giro de dicha bola se establece el cierre o la comunicación de paso entre sendos conductos opuestos del cuerpo de la válvula, incluyendo unas juntas empujadas por unos asientos, que establecen el cierre de estanqueidad necesario sobre la bola, dejando a ésta en libertad de giro."TOP ENTRY" ball valves they comprise a ball pierced by a hole, which is arranged inside a body, so that by turning it ball is established closing or passing communication between two opposite ducts of the valve body, including gaskets pushed by seats, which establish the closure of necessary tightness on the ball, leaving it free of turn.
Las operaciones de mantenimiento, por ejemplo para sustituir las juntas de estanqueidad, requieren el desmontaje de extracción de la bola, para poder retirar las juntas, así como la introducción posterior de dichos elementos en la realización del montaje, para lo cual es necesario separar los asientos que empujan a las juntas contra la bola, con el fin de poder extraer e introducir libremente los elementos internos en dichas operaciones.Maintenance operations, for example to replace the gaskets, they require disassembly of extraction of the ball, to be able to remove the joints, as well as the subsequent introduction of said elements in the realization of assembly, for which it is necessary to separate the pushing seats to the joints against the ball, in order to be able to extract e freely introduce the internal elements in said operations.
Esa separación de los asientos, para el desmontaje y montaje de las mencionadas válvulas, se soluciona actualmente mediante realizaciones de incorporación de una doble leva en el eje de giro de la bola, de manera que dicha doble leva separa los asientos presionando en dos puntos sobre los mismos, en tanto que otras realizaciones se basan en dar una inclinación a los asientos en el sentido de montaje, de forma que los asientos se montan y desmontan mediante un movimiento conjunto con la bola.That separation of the seats, for the disassembly and assembly of the mentioned valves, it is solved currently by means of incorporation of a double cam on the axis of rotation of the ball, so that said double cam separate the seats by pressing on two points on them, in so much so that other embodiments are based on giving an inclination to seats in the direction of assembly, so that the seats are assemble and disassemble by a joint movement with the ball.
Estas soluciones pertenecientes al estado de la
técnica presentan sin embargo problemas derivados de su propia
naturaleza, ya que el sistema de doble leva en el eje de la bola
necesita un sistema auxiliar de fijación de los asientos en la
posición abierta, para poder desmontar la bola, mientras que el
sistema de montaje y desmontaje de los asientos junto con la bola,
pude dañar las juntas y por ello en el montaje es necesario emplear
un utillaje accesorio de
montaje.These solutions belonging to the state of the art, however, present problems derived from their own nature, since the double cam system on the axis of the ball requires an auxiliary system for fixing the seats in the open position, in order to disassemble the ball. , while the system of assembly and disassembly of the seats together with the ball, could damage the joints and therefore in the assembly it is necessary to use an accessory tooling of
mounting.
Tales soluciones conocidas requieren por lo tanto un gran número de piezas, resultando sus realizaciones de una complejidad de mecanizado y ajuste que encarece mucho el producto, en tanto que cuando las válvulas son de dimensiones reducidas, la aplicación de dichas soluciones es impracticable o resulta de un costo muy elevado.Such known solutions require therefore both a large number of pieces, resulting in his accomplishments of a complexity of machining and adjustment that makes the product, while when the valves are of dimensions reduced, the application of such solutions is impracticable or It results in a very high cost.
De acuerdo con la invención se propone un dispositivo, mediante el cual se puede realizar de forma práctica y fácil la separación de los asientos de las válvulas de bola mencionadas, para el montaje y desmontaje de los elementos componentes interiores de las mimas.According to the invention, a device, by which it can be performed in a practical way and easy separation of ball valve seats mentioned, for the assembly and disassembly of the elements interior components of the mimes.

El objeto de la invención se refiere a un dispositivo destinado para facilitar el montaje y desmontaje de las válvulas de bola tipo "TOP ENTRY", con el cual se puede realizar de una manera sencilla y práctica la apertura necesaria para dejar libre el acceso de salida y entrada de los elementos componentes del interior de dichas válvulas.The object of the invention relates to a device designed to facilitate the assembly and disassembly of "TOP ENTRY" type ball valves, with which you can perform the necessary opening in a simple and practical way to free the access of exit and entrance of the elements components inside said valves.
El dispositivo preconizado comprende un conjunto de dos brazos (1) enfrentados, los cuales determinan un extremo libre (2) en forma de horquilla, mientras que por el otro extremo quedan unidos respectivamente a las partes móviles entre sí de un conjunto telescópico hidráulico (3).The recommended device comprises a set of two arms (1) facing each other, which determine one end free (2) in the form of a fork, while at the other end they are attached respectively to the moving parts of each other in a hydraulic telescopic assembly (3).
Dicho conjunto telescópico (3) se compone de dos camisas (3.1 y 3.2) que van acopladas axialmente entre sí en contraposición, determinando en el interior una cámara cerrada (4) que se llena de un fluido hidráulico, tal como aceite.Said telescopic assembly (3) consists of two shirts (3.1 and 3.2) that are axially coupled to each other in contraposition, determining inside a closed chamber (4) which is filled with a hydraulic fluid, such as oil.
Por un extremo del mencionado conjunto telescópico (3) entra por un paso de deslizamiento estanco (5) un vástago (6), el cual en el extremo que queda en el exterior determina una cabeza (7) para la manipulación de accionamiento giratorio del mismo, mientras que por el extremo que queda en el interior se acopla en relación roscada respecto de un eje (8) fijo que se extiende axialmente en la cámara (4) desde el otro extremo.At one end of the mentioned set telescopic (3) enters through a watertight sliding step (5) a stem (6), which at the end that is outside determines a head (7) for drive manipulation rotating it, while at the end that is in the inside is coupled in threaded relation with respect to a fixed axis (8) extending axially in the chamber (4) from the other extreme.
Con ello así, cuando se actúa giratoriamente el vástago (6), en el sentido de avance del mismo sobre el eje (8), merced al acoplamiento roscado entre ambos, se produce una entrada progresiva de dicho vástago (6) en la cámara (4), con lo cual aumenta la presión hidráulica en el interior y como consecuencia se origina un empuje entre las camisas (3.1 y 3.2), las cuales debido a dicho empuje se desplazan axialmente en el sentido de extensión del conjunto telescópico (3), como se observa en la figura 2.With this, when the rotation is performed rod (6), in the direction of its advance on the shaft (8), thanks to the threaded coupling between the two, an entry is produced progressive of said rod (6) in the chamber (4), whereby the hydraulic pressure inside increases and as a result causes a thrust between the shirts (3.1 and 3.2), which due to said thrust they move axially in the direction of extension of the telescopic assembly (3), as seen in Figure 2.
En ese desplazamiento relativo las camisas (3.1 y 3.2) llevan consigo a los respectivos brazos (1) que se halla unidos a ellas, con lo cual dichos brazos (1) se separan a mayor distancia entre sí, de modo que el dispositivo se comporta como una pinza de apertura, pudiendo ser utilizado como tal para la separación de elementos móviles o partes de mecanismos susceptibles de separación.In that relative displacement the shirts (3.1 and 3.2) carry with them the respective arms (1) found attached to them, whereby said arms (1) separate to greater distance from each other, so that the device behaves like a opening clamp, and can be used as such for the separation of moving elements or parts of susceptible mechanisms from separation.
De acuerdo con ello, el dispositivo es susceptible de aplicación para separar los asientos (9) que actuados por muelles (10) empujan a las juntas de estanqueidad (11) contra la bola (12) en las válvulas de bola tipo "TOP ENTRY", según se observa en las figuras 3 y 4, en las que se ha representado el mecanismo de una válvula de este tipo, sin la carcasa o cuerpo de alojamiento correspondiente.Accordingly, the device is susceptible of application to separate the seats (9) that operated by springs (10) push the seals (11) against the ball (12) in the ball valves type "TOP ENTRY", as seen in figures 3 and 4, in which it has been represented the mechanism of such a valve, without the housing or corresponding housing body.
En esta aplicación, mediante los brazos (1) del dispositivo se puede actuar la separación de los asientos (9) en contra de los muelles de empuje (10), para dejar entre dichos asientos (9) el espacio necesario para el paso libre de la bola (12) y las juntas (11), permitiendo así realizar de un modo rápido y con seguridad el montaje y desmontaje de las válvulas mencionadas, de modo que, cuando se realiza el montaje, una vez colocadas la bola (12) y las juntas (11) en su posición dentro del cuerpo de la válvula, girando el vástago (6) del dispositivo en el sentido de su avance en retroceso, se reduce la presión hidráulica en la cámara (4), con lo cual las camisas (3.1 y 3.2) pueden desplazarse en el sentido de aproximación de los brazos (1), cerrándose los asientos (9) contra la bola (12) merced al empuje de los muelles (10).In this application, using the arms (1) of the device can actuate the separation of the seats (9) in against the push springs (10), to leave between said seats (9) the space necessary for the free passage of the ball (12) and the joints (11), thus allowing to perform quickly and safely assembling and disassembling the valves mentioned, so that, when assembly is done, once placed the ball (12) and the seals (11) in position within the valve body, rotating the rod (6) of the device in the Direction of its advance in reverse, the hydraulic pressure is reduced in the chamber (4), whereby the shirts (3.1 and 3.2) can move in the direction of approach of the arms (1), the seats (9) being closed against the ball (12) thanks to the thrust of the docks (10).
El vástago (6) del dispositivo es axialmente hueco, poseyendo a través de la cabeza (7) un orificio de drenaje (13) que se sella mediante un tornillo (14) y una junta (15), mientras que en la extremidad que queda dentro de la cámara hidráulica (4) dicho vástago (6) posee una abertura radial (16), con lo cual a través del propio vástago (6) se pude realizar la introducción del fluido hidráulico a la mencionada cámara (4) para la disposición funcional del dispositivo.The rod (6) of the device is axially hollow, having a drain hole through the head (7) (13) sealed by a screw (14) and a gasket (15), while on the limb that is inside the chamber hydraulic (4) said rod (6) has a radial opening (16), whereby through the stem itself (6) the introduction of hydraulic fluid to said chamber (4) to the functional arrangement of the device.
