Structural advantages and performance characteristics of tubular check valves:
structural advantage
◆ The tubular check valve is a high-performance product designed and manufactured based on the experience of similar products at home and abroad and with partial improvements. It has applied for a national patent and is a unique patented product of our company.
◆ The valve adopts a multi-sealing structure. When in use, it can close tightly regardless of the pressure after the valve, overcoming the drawback of poor sealing performance of general check valves under low back pressure.
◆The profile design of the middle cavity of the valve body, while meeting the flow requirements, shortens the travel of the valve disc. Moreover, it adopts a spring return structure, which causes no or very little impact during opening and closing, and generates low noise.
◆ Due to the short opening and closing stroke and the use of spring return, it closes quickly. There is no friction between the sealing surfaces.
◆ The valve design adopts a streamlined flow channel, with low flow resistance and good energy-saving effect.
◆ The valve disc adopts a unique anti-erosion structure. When it is opened, the erosion of the fluid on the sealing surface will be greatly reduced, thereby increasing the service life of the valve.
◆ The unique floating connection structure of the valve stem and valve disc overcomes the deviation caused by wear during manufacturing and use, greatly improving the sealing performance.
◆ It can be designed as a slow-opening and slow-closing type to achieve the opening and closing of the valve without impact.
performance feature
◆ The valve closes tightly, has a small opening and closing impact, and closes quickly.
◆ The valve has a long service life.
◆ Easy to install, it can be installed at any position and is suitable for any place.
◆ Small in size and light in weight.
