The water hammer relief valve adopts a direct acting control structure, which is directly compared with the pressure in front of the valve through the spring. The pressure relief value can be adjusted on site.

The water hammer relief valve adopts a direct acting structure, so the valve can release pressure quickly and react quickly, which can effectively eliminate water hammer and protect the pressure safety of the pipe network to the maximum extent.

The water hammer relief valve is equipped with a hydraulic damping system. When the pressure in front of the valve is lower than the set value after the valve is released, the hydraulic damping system can control the valve to close slowly to prevent the secondary water hammer caused by the fast closing speed of the relief valve.

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

Product Overview

The pipeline water conveyance system uses the safety relief valve for water hammer protection, and there are countless cases of water hammer damage and personal injury in China. The water hammer relief valve developed by our company with the introduction of foreign advanced technology is a substitute for the safety relief valve, which is used in many domestic projects and has a good effect on water hammer protection.

The water hammer relief valve adopts a direct acting structure. When the high pressure wave of the pipe water hammer comes, it can quickly open the pressure relief valve to eliminate the water hammer. The set pressure of the water hammer relief valve spring can be adjusted to meet the needs of the site. When the pipeline pressure returns to normal, the valve shall be closed slowly at an adjustable speed to prevent secondary water hammer caused by valve closing too fast. The company used the best materials and the most advanced technology in the production of water hammer relief valves, and strictly implemented the quality control plan, effectively ensuring the hammer suppression performance of water hammer relief valves.

Working Principle

The water hammer relief valve adopts a direct acting structure. The pressure relief value is set directly by comparing the spring force in the valve with the pressure in front of the valve. When the pipe network pressure exceeds the set pressure value, the pressure in front of the valve will be greater than the spring force. The water hammer relief valve clack quickly opens to release the pressure under the pressure in front of the valve, effectively protecting the system. When the pressure in front of the valve recovers below the set pressure, the water hammer relief valve will be closed, and the valve will be closed slowly due to the effect of the hydraulic damping system. The closing speed of the water hammer relief valve can be adjusted by adjusting the upper limit flow check valve of the hydraulic damping system.
