AI Technical Summary
During use, clamp check valves can be damaged by water hammer when the fluid suddenly stops, increasing maintenance costs.
A clamp check valve with an EPDM valve disc is designed. It adopts a combination structure of valve disc body, mounting seat, slide groove, slider, buffer plate, compression spring and buffer pad. The rubber material and galvanized layer of the buffer plate and buffer pad absorb and buffer the impact energy of water flow, reducing damage to the valve disc.
The buffer structure reduces water hammer damage to the valve disc, extends the service life of the clamp check valve, and lowers maintenance costs.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0019] Embodiment:
[0020] As shown in the accompanying Figure 1 to the accompanying Figure 3 :
[0021] The utility model provides a kind of clamp check valve ethylene-propylene valve disc, including valve disc body 1, the top of valve disc body 1 is installed with several mounting seat 2 in equal distance of circumference, the top of mounting seat 2 is equipped with sliding slot 3, sliding block 4 is slidably installed in sliding slot 3, and the top of sliding block 4 extends to the outside of sliding slot 3, the top of several sliding blocks 4 is equipped with buffer plate 5, the top of buffer plate 5 is equipped with buffer pad 7, improve the buffering effect of buffer plate 5, the bottom of each sliding block 4 is equipped with compression spring 6, and the other end of compression spring 6 is connected with the bottom of sliding slot 3, the impact energy of water flow is absorbed and buffered by the elastic deformation of compression spring 6, to reduce the damage to valve disc body 1, and ethylene-propylene rubber pad 8 is installed on the circumferential side of the bottom of valve disc body 1.
[0022] Among them, the material of buffer pad 7 is rubber, and the rubber has good elasticity, can deform rapidly and store energy when impacted by water flow, and quickly recover to original shape and release energy after impact disappears.
[0023] Among them, the surface of valve disc body 1, the surface of mounting seat 2, the surface of sliding block 4 and the surface of buffer plate 5 are all provided with a zinc plating layer, which can effectively reduce the corrosion damage of moisture to each structure, thereby prolonging the service life of the whole device.
[0024] The working principle of the embodiment is as follows: when the water flow in the clamp check valve stops flowing and water hammer effect occurs, the water flow impacts on the buffer pad 7, simultaneously extruding the buffer pad 7 and the compression spring 6, so that the buffer plate 5 and the sliding block 4 move towards the direction of the sliding slot 3, the buffer pad 7 and the compression spring 6 can simultaneously absorb and buffer the impact of the water flow, and release the accumulated energy after the impact of the water flow dissipates, thereby reducing the damage to the valve disc body 1 and prolonging the service life of the clamp check valve.
