Stainless steel silencing check valve is a type of valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent the backflow of the medium. It is also known as a check valve, one-way valve, soundproof check valve, backflow valve, and back pressure valves. Its main function is to prevent medium backflow, prevent pump and drive motor from reversing, and prevent the release of container medium. The soundproof check valve with stainless steel structure is suitable for drainage pipes, such as HDPE drainage pipe and PVC drainage pipe. When the pump is stopped, the spring assisted valve shuttle is used to quickly close in advance when the positive flow rate approaches zero, effectively preventing water hammer and eliminating noise. In addition, stainless steel soundproof check valves are widely used in various water treatment equipment, such as installed at the bottom of the well, replacing the role of bottom valves, effectively intercepting impurities, and preventing blockages in pumps and other equipment.
Check valve maintenance
1. Storage and transportation: the hoist should be closed, the flap should be fixed in the open position, the inner openings at both ends of the drift diameter should be blocked with foam plates, and the ports should be plugged with blind caps to prevent dust and rust, and keep the channel clean and the end face flat.
2. Regular inspection: Check the dirt and rust on the two channels and sealing surfaces, as well as the protection status of the welding interface every three months, wipe them off, and reapply anti rust oil.
3. Installation location: The silencing check valves should be stored in a dry and ventilated room to prevent moisture, rain, and rust. It is generally suitable for clean media and should not be used for media containing solid particles and high viscosity.
4. Function and maintenance: including cleaning, lubrication, inspection of sealing components and fasteners, etc., to ensure the normal operation of the valve and extend its service life
Choose Suggestions
When choosing between stainless steel soundproof check valves or gate valves, specific application scenarios and requirements need to be considered. If the goal is to prevent water hammer and reduce noise, especially at the outlet of the water pump, stainless steel soundproof check valves would be a more suitable choice. If flow control or complete blockage of fluid flow is required in pipeline systems, gate valves are more suitable.
