In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1 to 7, the following technical solutions are adopted in the present embodiment: a multifunctional waterway valve moving membrane structure comprises a moving membrane body A, wherein the moving membrane body A consists of a sealing position 1, a telescopic membrane 2, a water sealing boss 3, a pilot hole 4, a flow limiting boss 5, a slow pressure groove 6 and a water sealing surface 7, and the moving membrane body A is of a moving membrane structure which is integrally formed by soft materials; the inner side of the sealing position 1 is provided with a telescopic film 2, a water sealing boss 3 is arranged below the telescopic film 2, the sealing position 1 is connected with the telescopic film 2, and the telescopic film 2 is connected with the water sealing boss 3; the bottom of the water sealing boss 3 is provided with a water sealing surface 7, the bottom of the water sealing surface 7 is provided with a flow limiting boss 5 used for limiting water flow when the valve is closed, the bottom of the flow limiting boss 5 is provided with a pressure relieving groove 6, and the center of the whole movable membrane body A is provided with a pilot hole 4 which completely penetrates through the top and the bottom of the movable membrane.
The sealing position 1 of the movable membrane of the specific embodiment is used for sealing the movable membrane body A and a valve seat B, a membrane support C, an electromagnetic valve D and a pressure maintaining cavity pressure cover (valve cover) which are matched for use, so that pressure leakage or seepage is prevented. The movable membrane body A is integrally formed by soft elastic materials such as rubber, silica gel or elastic plastic, the movable membrane can enable the water sealing boss 3 and the telescopic membrane 2 to move together according to the pushing of a water pressure acting force, and the water sealing surface 7 at the bottom of the water sealing boss 3 is used for being mutually attached to or separated from the water sealing surface of a matched valve or a matched membrane support, so that the effect of water switching is achieved; the flow-limiting boss 5 at the bottom of the water sealing surface 7 is used for being matched with a matched valve water inlet E or the inner wall of a water inlet of the membrane bracket to achieve the effect of limiting water flow; the flow-limiting boss 5 can be designed into different shapes according to actual needs, and the shapes of the flow-limiting boss include but are not limited to a cylindrical ring shape, a cylindrical conical ring shape, a cylindrical ring shape with ribs added externally, a cylindrical ring shape with concave limiting added externally, and the like.
The pressure-relieving groove 6 at the bottom of the flow-limiting boss 5 is used for relieving the flow velocity of water flow in the direction of a valve water inlet E or a diaphragm support water inlet which is used in a matched manner, and generates a hydraulic pressure acting force on each surface of the pressure-relieving groove 6 through the hydraulic pressure acting force to enable the pressure-relieving groove to deform, and the deformation of the flow-limiting boss 5 and the deformation of the pilot hole 4 can be adjusted according to the hydraulic pressure acting force; the shape of the inner concave groove of the pressure-relieving groove 6 can be designed into different shapes according to actual conditions, and one or more pressure-relieving grooves 6 can be arranged.

This embodiment can receive the influence of the inside water pressure effort of water route valve when in actual application (fig. 6, 7), the water pressure effort of water inlet direction can be through the effort that slowly presses recess 6 and apply all directions, move the current-limiting boss 5 of membrane and produce deformation to the outside, because of the size of water route valve water inlet or the diaphragm support water inlet of supporting use is fixed, so when current-limiting boss 5 produced deformation, can reduce the water flow area of current-limiting boss 5 and the water route valve water inlet or the diaphragm support water inlet of supporting use, thereby it is littleer to reach the discharge when water pressure effort is big more, thereby can not block the water velocity in the water route at once when reaching fast shut-off valve, water flow reduces or eliminates the water hammer (water hammer) when closing the valve. The same principle, when closing the valve, when closing, the water sealing surface 7 of moving membrane is close to the valve water inlet or the water sealing surface of the membrane support water inlet that the supporting used, the water pressure effort can rise in the twinkling of an eye, make the pilot hole 4 receive the deformation effort influence and diminish in the twinkling of an eye, can slow down rivers and get into the pressure chamber at moving membrane top through pilot hole 4, produce reaction time when closing for the valve, let the rivers speed of pipeline will be minimum in the twinkling of an eye and can not stop in the twinkling of an eye, the inside rivers of pipeline are because of the velocity of flow low, the flow diminishes, thereby can not produce high pressure differential, reduce the water hammer value, because the pilot hole 4 only takes place big deformation in the twinkling of an eye that the valve closed, so do not influence the time that the valve closed, thereby accomplish fast effect of closing the valve when reaching control water hammer value.
This embodiment can cooperate various water route valve products to use, like toilet valve, solenoid valve, mechanical valve, delay valve, irrigation valve etc. the stable performance solves the flexible characteristic of elasticity through soft material that water hammer value is high (water hammer effect), closes the valve abnormal sound, closes valve time overlength, product life weak point scheduling problem, and its technical advantage lies in:
(1) The membrane assembly has the advantages that the prior guide pillar of the original membrane assembly is omitted, the membrane assembly is directly integrally formed by soft materials and is formed by using a single part, the whole membrane assembly is only provided with one part, the membrane assembly can be directly used after being formed by a die, other assembling procedures are not needed for secondary production or assembly, mass production is easy, the membrane assembly has the effects of low production cost and high production speed, and social resources such as manpower and material resources are greatly saved.
(2) The movable membrane can automatically adjust the size of the pilot hole and the deformation of the flow-limiting boss according to the influence of the water pressure acting force to limit the water flow to buffer the water pressure and water flow speed impact when the valve is closed, thereby greatly reducing the destructive power of water hammer on the valve and the pipeline, effectively protecting the valve and the pipeline, and greatly prolonging the service life and stability of matched products.
(3) Lead to and use the material production of soft performance to form, can not produce abnormal sound, resonance when making its hard valve part contact or the friction with supporting use to promote product experience effect greatly, reduce the emergence of closing the valve noise, improve people's use greatly and experience the effect, optimize and experience the ambient noise.
(4) The dynamic membrane has the advantages of simple structure and single component, greatly improves the stability, service life and production efficiency of the dynamic membrane in different water pressure environments, meets the market development and requirements, and has wide market application prospect in the application of waterway valves.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
