Definitions

  • the invention relates to valves for liquids and gases, which are attached to containers, in particular to pressure vessels
  • Valves of this type are used for emptying and filling the containers with or with liquids and for degassing and gassing, in particular ventilation and ventilation of the containers. They are used, for example, on filter housings which are equipped with filter modules and are operated under a pressure difference
  • valves In many areas, in particular in the filtration of fluids in the pharmaceutical, biotechnological and food technology industries, valves must be used which meet the following requirements. Ensuring high operational safety, such as the possibility of removal of the valve needle or ineffectiveness of the valve seal due to improper use Operation, exclusion of areas that are difficult to access and dead volumes that prevent absolute cleaning of the valve or removal of unwanted media, guarantee easy maintenance, for example for the replacement of seals by inexperienced personnel, cost-effective manufacture.
  • the valves of the prior art meet these requirements not fair
  • a hollow valve needle made of stainless steel located in a valve housing with a cylindrical valve seat is provided with a seal.
  • the seal is made for reasons of high chemical resistance made of plastic, for example polytetrafluoroethylene It is disadvantageous that the seal is pressed into the valve opening if the valve is improperly closed, which can lead to the fact that when the valve is opened The valve detaches the seal from the valve needle and closes the valve opening or jams the valve, rendering it unusable.
  • the seals must have a planar surface. Therefore, the seal must be turned flat after it has been placed on the valve needle.
  • valve needle has its valve needle completely out the valve seat can be unscrewed, a liquid or gas flow can no longer be controlled in this state.This can lead to contamination of the environment and injuries to the operating personnel. It is known to prevent the valve needle from being pulled out by means of a chain which is attached to the valve housing and above the valve needle is inserted However, the chain is an additional component that is difficult to clean and therefore unsuitable for work in clean room or under sterile conditions. It is also disadvantageous that a thread inside the valve housing represents a collection of corners and edges, which are difficult to clean and can cause contamination of the fluids
  • the invention has for its object to provide a valve for liquids and gases, which ensures high operational reliability, good cleaning and easy maintenance
  • the valve according to the invention for liquids and gases consists at least of a valve housing with a cylindrical valve seat with a through-hole, via which the valve can be communicatively connected to a container, and a valve needle equipped with a channel for the liquids and gases and a closed tip in the valve housing with the cylindrical valve seat is arranged movably such that the tip with seal in the closed state of the valve extends to the through hole
  • the tip of the valve needle has an outer profile, over which the seal, preferably made of plastic, is located with an inner profile that is inverse to the outer profile.
  • the profiles are designed in the manner of a snap lock A particularly tight fit of the seal on the tip of the valve needle is achieved.
  • valve needle Even if the valve needle has been tightened with the aid of tools such as pliers or spanners, the seal can deform, and it will come loose when the valve is opened but not from the tip of the valve needle. This ensures that the valve remains operational even if it is not handled properly
  • the seal to be replaced can be removed from the tip of the valve needle by means of a tool, for example pliers, as a rule only by destroying the seal, or at least the inner profile.
  • a tool for example pliers
  • the new equipment can be used so that the new seal is placed with the sealing surface facing down on a smooth surface and the valve needle with the profiled tip is pressed into the profile opening of the seal until the profiles snap into place Safe maintenance even by inexperienced personnel.
  • the design of the profiles means that there are no dead spaces between the seal and the valve needle in which contaminations that are difficult to remove could accumulate.
  • the seal is in its front area to seal the through hole trapezoidal, whereby a particularly good fit of the seal is achieved in the closed state of the valve
  • the valve housing is provided with an external thread and a union nut running thereon, with which the valve needle can be moved along the longitudinal axis of the valve housing to open and close the valve.
  • the union nut projects beyond the external thread in a length which, in the closed valve state, is at least that

  • the snap ring can be removed from the union nut using standard tools.
  • This securing device can be installed almost independently of the valve's installation position are, provided that there is enough space between the external thread of the valve housing and the container on which the valve is located, with a distance of about 1 cm is sufficient.
  • a fuse is a common Sic Production by means of a chain or similar considerations
  • a set screw fulfills the securing function.
  • the union nut is penetrated in the area of its edge pointing in the direction of the through hole by a set screw which is attached in such a way that it reaches the maximum permissible distance the valve needle for opening the valve on the external thread of the valve housing, limiting this distance, is also applied. It can also be tightened in any position of the valve needle to lock the respective valve state
  • the union nut is designed so that the Venil can be opened and closed both with a tool, for example with an open-end wrench, and by hand. Opening by means of a tool is useful if the valve is too hot for manual operation but it has proven to be advantageous to provide the union nut on its outer circumference with a handwheel, preferably made of a material that is a poor heat conductor

Abstract

L'invention concerne une soupape (1) pour liquides et gaz, montée sur des contenants sous pression. Ces soupapes doivent garantir une grande sécurité de fonctionnement, et pouvoir être bien nettoyées et facilement entretenues. Un pointeau de soupape (5), monté dans un corps de soupape (2) comportant un siège de soupape (3) cylindrique, présente, sur sa pointe (9), un profil extérieur sur lequel est placé un joint (10) dont le profil intérieur correspond au profil extérieur de la pointe, ces deux profils constituant une fermeture à déclic (11). De telles soupapes sont utilisées pour la vidange et le remplissage des contenants avec des liquides, ainsi que pour le dégazage et le remplissage avec du gaz, en particulier la vidange d'air ou l'aération des contenants. Ces soupapes sont, par exemple, utilisées sur des boîtiers de filtre qui sont pourvus d'un module de filtration et fonctionnent sous un différentiel de pression.
