The pipeline water transportation system in China adopts safety pressure relief valves for water hammer protection. However, there are countless cases of water hammer damage and personal injuries caused by such valves. The water hammer relief valve developed by our company through the introduction of foreign advanced technologies is an alternative to the safety pressure relief valve. It has been used in many domestic projects and has achieved good.

results in water hammer protection. The water hammer relief valve adopts a direct-acting structure. When a high-pressure wave of pipeline water hammer arrives, it can quickly open to relieve pressure and eliminate the water hammer. The set pressure of the spring in the water hammer relief valve can be adjusted to meet the on-site requirements. When the pipeline pressure returns to normal, the valve closes slowly at an adjustable speed to prevent the generation of secondary water hammer due to rapid valve closure. During the production of the water hammer relief valve, our company uses the best materials and the most advanced technologies, and strictly implements the quality control plan, effectively ensuring the water hammer elimination performance of the valve.

The water hammer relief valve adopts a direct-acting control structure, directly comparing the pressure before the valve with the spring force. The pressure relief value can be adjusted on-site.

Due to the direct-acting structure, the valve can relieve pressure quickly and respond rapidly, effectively eliminating water hammer and maximizing the pressure safety of the pipeline network.

The water hammer relief valve is equipped with a hydraulic damping system. After the valve relieves pressure, when the pressure before the valve is lower than the set value, the hydraulic damping system can control the valve to close slowly, preventing secondary water hammer caused by the rapid closing speed of the pressure relief valve.

The closing speed of the valve can be adjusted according to the on-site working conditions to achieve the best effect.

The water hammer relief valve adopts a direct-acting structure. The pressure relief value is set by directly comparing the spring force inside the valve with the pressure before the valve. When the pipeline pressure exceeds the set pressure value, the pressure before the valve will be greater than the spring force, and the valve disc of the water hammer relief valve will quickly open under the pressure before the valve to relieve pressure, effectively protecting the system. When the pressure before the valve drops below the set pressure, the water hammer relief valve will close. Due to the action of the hydraulic damping system, the valve will close slowly. By adjusting the flow control check valve in the hydraulic damping system, the closing speed of the water hammer relief valve can be regulated.
