The problems that when high-speed water flow passes through the valve, impact can be generated on a sealing valve seat, a valve rod and other components of the valve, and the valve components which are impacted by the water flow for a long time are likely to be subjected to fatigue damage, so that the components are abraded and eroded are solved. The impact-resistant water pipe valve comprises a valve body, a water inlet pipe and a water outlet pipe are arranged at the two ends of the valve body respectively, flanges are arranged on the water inlet pipe and the water outlet pipe respectively, a buffer assembly is arranged on the inner side of the water inlet pipe and comprises a shell arranged on the inner side of the water inlet pipe, a fixing plate is fixedly arranged on the shell, and a buffer plate is arranged on one side of the fixing plate. The valve has the advantages that the path of water flow is changed, and after the water flow is divided and flows out from the two sides of the fixing plate, the impact force of the water flow to components in the valve body is reduced, and the damage of the water flow to the components in the valve body is reduced.

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to an impact-resistant water pipe valve, in particular to an impact-resistant water pipe valve. Background Art

[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief.

[0003] During the use of the valve, when high-speed water flows through the valve, it will impact the valve seat, valve stem and other components of the valve. Valve components that are impacted by water flow for a long time may suffer fatigue damage, resulting in wear and erosion of these components, seriously affecting the performance and safety of the valve. Therefore, it is of great significance to design an impact-resistant water pipe valve. Summary of the invention

[0004] The utility model aims to provide an impact-resistant water pipe valve in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an impact-resistant water pipe valve, including a valve body, characterized in that an inlet pipe and a water outlet pipe are respectively arranged at both ends of the valve body, flanges are arranged on the water inlet pipe and the water outlet pipe, a buffer assembly is arranged on the inner side of the water inlet pipe, the buffer assembly includes a shell arranged on the inner side of the water inlet pipe, a fixing plate is fixedly arranged on the shell, a buffer plate is arranged on one side of the fixing plate, and a spring is fixedly arranged between the buffer plate and the fixing plate.

[0006] In the above-mentioned impact-resistant water pipe valve, a guide rod is fixedly provided on one side of the buffer plate, and one end of the guide rod passes through the fixed plate and is fixedly provided with a limiting block.

[0007] In the above-mentioned impact-resistant water pipe valve, a mounting plate is fixedly arranged on one side of the shell, and a plurality of positioning rods are fixedly arranged on one side of the mounting plate.

[0008] In the above-mentioned impact-resistant water pipe valve, the inner wall of the water inlet pipe is provided with a plurality of positioning holes used in conjunction with the positioning rods.

[0009] Compared with the prior art, the impact-resistant water pipe valve mitigates the impact of high-speed water flow and changes the path of the water flow under the action of the buffer plate and the spring, so that the water flow is diverted and flows out from both sides of the fixed plate, thereby reducing the impact force of the water flow on the internal components of the valve body and reducing the damage of the water flow to the internal components of the valve body.
