The Check Valve can rotate 90 degrees and close firmly with a small rotation torque. The completely equal valve body cavity has little resistance to the medium and provides a straight flow path. The main features of the Check Valve are its compact structure, easy operation and easy repair. Check Valve can be used to control the flow of various fluids such as air, water, steam, various corrosive media, muddy water, oil, liquid metal and radioactive media. The valve body can be integral or combined. This kind of Universal Valve is generally installed horizontally in the pipe.
The working principle of the Check Valve: turning the core of the valve makes the Universal Valve open and close. The valve has a light switch, small size, can be made into a large diameter, reliable sealing, simple structure, and easy repair. The sealing surface and spherical surface are often in a closed state and are not easily eroded by the media. It is frequently used in various industries. Check Valve are mainly used in pipelines to cut off, distribute and change the flow direction of media.
1. Advantages of Check Valve
① The fluid resistance is small, and its resistance coefficient is equal to the same length of pipe section.
②Simple structure, small size and light weight.
③Tight and reliable, the Check Valve sealing surface material is widely used in plastics and sealing properties. Vacuum systems are also widely used.
④Easy to operate, open and close quickly, rotate 90° from fully open to fully closed, convenient for remote control.
⑤Easy to repair, the Check Valve has a simple structure and the sealing ring is generally movable. It is very convenient to disassemble and exchange.
⑥When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the passage of the medium will not cause erosion of the sealing surface of the Universal Valve.
2. Maintenance method of Check Valve
① After the rough product is finished, it must be rinsed clean after pickling. If there are sand holes or perforations, they should be welded with gas shielded argon arc welding. It is then polished and solid solution treated.
②Finished product, after processing and pressure test is completed. It should be rinsed with water added with anti-rust powder.
③ During transportation, try to use wooden boxes for packaging and avoid contact with metal products.
④After installing the pipeline, perform regular maintenance and upkeep on it, such as frequently applying lubricating oil to the
Valve Stem. Open and close the Universal Valve appropriately several times. Make it difficult for the inner ball, valve stem and sealing surface to assimilate.
