Definitions
- This application for a patent of invention relates to a dual-action valve used in high-pressure pumps, particularly for pumping fluids.
- dual-action valves are known in the state of the art, and are normally used in high-pressure pumps. These valves are called dual action as they allow fluid to flow in both the forward and return strokes of a piston, for example.
- valves Although they are widely used in the market, most of these valves possess certain features such as the use of resilient materials next to the seal, generating less stability and a greater incidence of leaks, as well as often presenting stability problems due to a reduced length in relation to the theoretically ideal length; in addition, these known dual-action valves have a diameter that is considered relatively large, thus also running into problems related to material costs. Furthermore, it is normal for the current valves to use a single spring, which reduces the device's useful life, as well as a through shaft seal, which increases resistance to the flow of fluid, resulting in lower efficiency.
- a spring is positioned between the aforesaid discharge valve element and the aspiration valve element, and said spring continually activates the discharge and aspiration valve elements, in relation to the closed portion.
- the aspiration valve element is opened and the fluid enters the pump chamber through the aforesaid radial suction openings.
- the power stroke the fluid is discharged through a central hole and lateral feed channels in the discharge valve element in the open position.
- Another object of the invention is to obtain a dual-action valve in which the sealing angle is configured as metal/metal, ensuring greater stability for the assembly and determining a lower incidence of leaks.
- the CONSTRUCTIVE ARRANGEMENT APPLIED IN A DUAL-ACTION VALVE is intended preferentially to be used in a head block, and essentially consists of a suction valve and a pressure valve, with a compression spring in each of the aforesaid valves.
- the compression spring of the suction valve is supported on a spring support, on which a split ring operates, while the compression spring of the pressure valve is housed in a pressure spring guide.
- the double seat forms the metal/metal seal angle, while the suction valve works within a piston liner, with openings for fluid intake, whereas a longitudinal conduit, when the piston advances, makes the fluid flow into the high-pressure duct within the head.
- the high-pressure fluid feeding operation becomes more efficient, with an increased useful life and without flow variations determined by the problems with a single system spring.
- the CONSTRUCTIVE ARRANGEMENT APPLIED IN A DUAL-ACTION VALVE consists of a valve (V) to be used in high-pressure systems, and, in the example shown in this patent, the aforesaid valve (V) is inserted into a head (C1), showing the fixing elements (E1) and the high-pressure outlet (AP) of the valve (V) to the cited head (C1).
- valve (V) particularly by means of its suction side (L1), is coupled to the piston liner (C2) which is connected to the crankshaft (not shown).
- the valve (V) itself is provided with a double seat (1) of a cylindrical kind and provided with a peripheral sealing ring (2), and said double seat (1) has on one side the suction valve (3) and on the other side the pressure valve (4).
- the latter consists of a more elongated cylindrical body (5), of smaller diameter, with external sealing rings (6).
- the double seat (1) receives longitudinal hollow conduits (7) that have one end with an opening (8) for fluid inflow, the opposite ends of said longitudinal hollow conduits (7) having the suction valve (3), on which is supported one end of the compression spring (9), whose opposite end abuts the spring support (10), where is applied a split locking ring (11).
- the double seat (1) is traversed by a longitudinal channel (12) extending from the suction side to the pressure side, to communicate with the high-pressure outlet (AP).
- the dual-action seat (1) has a sealing angle (13) that is made of metal with metal, to ensure greater stability and reduce the incidence of eventual fluid leaks.
- the pressure valve (4) receives a pressure spring guide (14) and the compression spring itself (15), which has a smaller diameter than the compression spring (9).
- this valve by creating a construction to receive two springs, managed to design, with this construction, a dual-action valve of greater length, ensuring greater stability, to reduce the diameter and to save material and, above all, to increase the useful life of the valve, which is a solution that the market wants and expects, because the procedures for preventive and corrective maintenance incur a loss of time and labour and generate costs.
- valve in this patent application is operated by actuating the piston (P) in the retracting direction, in order to create negative pressure inside the liner (C2) and thereby create positive pressure in (16) and allow the flow of fluid to the interior of said liner (C2).
- the operating cycle of the high-pressure valve occurs efficiently, and achieves a number of useful life cycles which is substantially optimized in relation to the valves that use a single spring.
