A quick-closing check valve, also known as a "quick closure valve" or a "fast closing valve," is a type of valve that is designed to close rapidly in response to certain conditions. These valves are commonly used in applications where the prevention of backflow is critical, such as in pipeline systems or high-pressure systems.
The main purpose of a quick-closing check valve is to prevent the reverse flow of fluid or gas in a system. When the flow direction is normal, the valve remains open, allowing the fluid or gas to pass through. However, if the flow direction changes or exceeds a certain pressure threshold, the valve quickly closes to prevent backflow.
Product description:
The (DYH41X) quick-closing check valve produced by our company consists of valve seat, valve stem, spring, valve disc, guide sleeve and other parts in the valve body. When the pump is turned on, the disc rises under the thrust of the bottom of the water.
At the same time, the spring is quickly closed under the action of the spring force. When the water flow is close to 0, the valve disc is completely closed. There is no water backflow phenomenon, and at the same time, because the water cannot flow back, no kinetic energy is generated, so the generation of water hammer is prevented. Its characteristics: 1. Prevent water hammer; 2. No sound when closing; 3. Small head loss; 4. Wide range of use; 5. Good sealing effect. Applicable to clean water, sewage and other systems
