H41N / F Lifting Gas Check Valve
H41N / F Lifting Gas Check Valve Structure
H41N / F lifting gas check valve uses the fluid pressure difference and its weight to achieve lifting. It is suitable for most of the horizontal pipelines in the tank. It automatically prevents the medium from flowing backward and protects upstream equipment. It is suitable for liquefied petroleum gas and natural gas. , Gas and other media as a one-way flow device.
The gas lift check valve opens and closes by itself based on the flow of the medium and the force. It uses PTFE or nylon plastic as the material of the sealing surface, and uses the polytetrafluoroethylene or nylon plastic to generate a small amount under the action of the medium pressure. The deformation improves the sealing performance, slows down the impact of the pressure of the medium, prevents sparks caused by static electricity, protects valves and pipelines, and is suitable for gas pipelines. Its role is to prevent the medium in natural gas, gas, coal gas, and liquefied petroleum gas pipelines from flowing backward.
- Teflon or nylon plastic is used as the sealing surface material to improve the sealing performance.
- The resistance is small, and the lifting and lowering is realized by using the fluid pressure difference and its own weight.
- The valve is a fully enclosed structure with no moving seal and never leaks.
