A water hammer prevention valve is a highly complex piece of equipment that includes many components such as a main valve, a bleed valve, a high-pressure hydraulic pilot valve, a solenoid pilot valve, a low-pressure pressure switch, a conduit and an electronic control box. These components work together to ensure the safety of the pumping station.
Water hammer prevention valves have a variety of functions, the most notable of which are hydraulic automatic control and electronic automatic control. Under high pressure conditions, it can unconditionally open the drain to prevent water hammer. Under low-voltage conditions, it can be turned on in advance, and when the power is off, or accompanied by low-voltage opening, the water hammer can be discharged to further prevent water hammer. The design of the main valve is even more exquisite, which can realize fast opening and slow closing, effectively prevent water hammer when closing the valve by itself, and provide multiple guarantees for the system.
Water hammer prevention valves are usually installed on the main water supply line at the outlet of the pump, close to the source where water hammer may occur, such as check valves. By means of an external connection to the T-tee, it can be opened in advance to prevent water hammer and unconditionally discharge high-pressure water hammer if necessary. This design makes the pumping station safer and effectively improves the safety and reliability of the system.
Overall, the water hammer prevention valve is an indispensable piece of equipment that is of great significance for ensuring the safe operation of the pumping station. Through its ingenious design and the synergy of various functions, it provides strong support for the entire system, enabling the pumping station to operate stably under various conditions.
