At the same time, due to the uneven quality, it is not conducive to mass production and promotion. The traditional water valve diaphragm is composed of multiple parts. The hard material parts are easy to rub against the inlet and outlet parts of the valve to produce abnormal closing noise and resonance. Because the hard material parts cannot deform and adjust the size of the water hole according to the influence of water pressure, the high water pressure state is the closing valve water hammer value (water hammer effect), which causes the whole valve to not close due to vibration, the connection of the parts is loose and leaking due to vibration, and the product life is short. There are adverse consequences such as the risk of flooding and waste of water resources.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] Reference Figure 1-7 , this specific embodiment adopts the following technical scheme: a multifunctional waterway valve dynamic membrane structure, including a dynamic membrane body A, the dynamic membrane body A is composed of a sealing position 1, a telescopic membrane 2, a water-sealing boss 3, a pilot hole 4, a flow-limiting boss 5, a pressure-relief groove 6 and a water-sealing surface 7, and the dynamic membrane body A adopts a dynamic membrane structure integrally formed of a soft material; a telescopic membrane 2 is arranged on the inner side of the sealing position 1, a water-sealing boss 3 is arranged below the telescopic membrane 2, the sealing position 1 is connected to the telescopic membrane 2, and the telescopic membrane 2 is connected to the water-sealing boss 3; a water-sealing surface 7 is arranged at the bottom of the water-sealing boss 3, a flow-limiting boss 5 for limiting the flow of water when closing the valve is arranged at the bottom of the water-sealing surface 7, a pressure-relief groove 6 is arranged at the bottom of the flow-limiting boss 5, and a pilot hole 4 that completely penetrates the top and bottom of the dynamic membrane is arranged at the center position of the entire dynamic membrane body A.

[0021] The sealing position 1 of the dynamic membrane in this specific embodiment is used for mutual sealing between the dynamic membrane body A and the matching valve seat B, diaphragm bracket C, solenoid valve D, and pressure cover (valve cover) of the pressure-maintaining chamber to prevent pressure leakage or seepage. The dynamic membrane body A is formed in one piece with soft elastic materials such as rubber, silicone or elastic plastic. The dynamic membrane can move the water sealing boss 3 and the telescopic membrane 2 together according to the push of the water pressure force. The water sealing surface 7 at the bottom of the water sealing boss 3 is used to fit or leave the matching valve water sealing surface or the matching diaphragm bracket water sealing surface to achieve the effect of switching water; the flow limiting boss 5 at the bottom of the water sealing surface 7 is used to cooperate with the matching valve water inlet E or the inner wall of the diaphragm bracket water inlet to achieve the effect of limiting the flow of water; the flow limiting boss 5 can be designed into different shapes according to actual needs, and its appearance includes but is not limited to cylindrical ring type, cylindrical cone ring type, cylindrical ring type with external ribs, cylindrical ring type with external concave limiter, etc.

[0022] The pressure-relieving groove 6 at the bottom of the flow-limiting boss 5 is used to slow down the water flow velocity in the direction of the water inlet E of the matching valve or the water inlet of the diaphragm bracket, and generates a water pressure force on each surface of the pressure-relieving groove 6 through the water pressure force to cause it to deform. The deformation of the flow-limiting boss 5 and the pilot hole 4 can be adjusted according to the water pressure force; the inner concave groove shape of the pressure-relieving groove 6 can be designed into different shapes according to actual conditions, and the pressure-relieving groove 6 can be provided with one or more.

[0023] The pilot hole 4 is used for the water flow from the water inlet E of the valve or the water inlet of the diaphragm bracket used in conjunction with the moving diaphragm to enter the top of the moving diaphragm. The self-cleaning needle F is used in the pilot hole 4 to move the moving diaphragm up and down through the water pressure force to achieve the effect of switching the valve.

[0024] This specific implementation method is practically applied ( Figure 6 , 7 ) will be affected by the water pressure force inside the water circuit valve. The water pressure force in the direction of the water inlet will apply forces in all directions through the pressure-relieving groove 6, causing the flow-limiting boss 5 of the dynamic membrane to deform outward. Since the size of the water inlet of the water circuit valve or the water inlet of the diaphragm bracket used in conjunction with it is fixed, when the flow-limiting boss 5 is deformed, the water flow area of ​​the flow-limiting boss 5 and the water inlet of the water circuit valve or the water inlet of the diaphragm bracket used in conjunction with it will be reduced, thereby achieving the goal that the greater the water pressure force, the smaller the water flow rate passing through, thereby achieving the goal of not immediately blocking the water flow velocity and water flow rate in the water circuit when the valve is quickly closed, thereby reducing or eliminating the water hammer value (water hammer) when the valve is closed. By the same principle, when the valve is close to closing, that is, when the water sealing surface 7 of the dynamic membrane is close to the water inlet of the matching valve or the water sealing surface of the water inlet of the diaphragm bracket, the water pressure force will increase instantly, causing the pilot hole 4 to be affected by the deformation force and instantly become smaller, which can slow down the water flow through the pilot hole 4 into the pressure chamber on the top of the dynamic membrane, giving the valve reaction time when it is closed, so that the water flow speed in the pipeline will instantly drop to the minimum instead of stopping instantly. The water flow inside the pipeline will not produce a high pressure difference due to the low flow rate and small flow rate, thereby reducing the water hammer value. Because the pilot hole 4 only undergoes a large deformation at the moment the valve is closed, it does not affect the valve closing time, thereby achieving the effect of controlling the water hammer value while also achieving the effect of quickly closing the valve.

[0025] This specific implementation can be used with various water valve products, such as toilet valves, solenoid valves, mechanical valves, delay valves, irrigation valves, etc., with stable performance. The elasticity and expansion characteristics of soft materials can solve the problems of high water hammer value (water hammer effect), abnormal valve closing sound, long valve closing time, short product service life, etc. Its technical advantages are:

[0026] (1) The pilot column of the original diaphragm assembly is eliminated, and a soft material is directly used for one-piece molding. The entire assembly has only one component and can be used directly after being molded. There is no need for other assembly processes for secondary production or assembly. It is easy to mass produce, has the effects of low production cost and high production speed, and greatly saves social resources such as manpower and material resources.

[0027] (2) The dynamic diaphragm can adjust the size of the pilot hole and the deformation of the flow-limiting boss according to the influence of the water pressure to limit the water flow rate and buffer the impact of water pressure and water flow velocity when closing the valve, thereby greatly reducing the destructive force of water hammer on valves and pipelines, effectively protecting valves and pipelines, and greatly extending the service life and stability of supporting products.

[0028] (3) It is made of soft materials, which can prevent abnormal noise and resonance when it contacts or rubs with the matching hard valve components, thereby greatly improving the product experience, reducing the occurrence of valve closing noise, greatly improving people's user experience, and optimizing the experience of environmental noise.

[0029] (4) The structure is simple and the components are single, which greatly improves the stability, service life and production efficiency of the dynamic diaphragm under different water pressure environments, conforms to market development and needs, and has broad market application prospects in water valves.

[0030] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
