Buried gas soft-sealed gate valve

The buried gas soft-sealed gate valve is a proprietary technology of pipeline valves for natural gas pipeline transportation systems introduced from a German company. After long-term digestion, absorption and improvement by our company, its performance has reached the leading position in China. Gas soft-sealed gate valves are mainly applicable to places such as the transportation and storage stations of natural gas and liquefied gas in urban gas pipeline networks. The gas soft-sealed gate valve can be directly buried underground. Just build a small valve chamber above the valve cover, and it can be operated and maintained in all directions on the ground. It has good sealing performance, a small flow resistance coefficient, and is convenient for operation and maintenance. The gas soft-sealed gate valve system has a long service life and is an ideal supporting product for urban gas, natural gas and other pipelines. This product is divided into flange connection and welded end according to the working conditions of use. The system product can be driven by manual, electric, bevel gear transmission and extremely traditional methods according to the user's usage requirements.

Structural description and working principle of buried gas soft-sealed gate valve

The gas soft-sealed gate valve adopts a concealed stem wedge single gate valve structure, and the valve body and valve cover are connected by countersunk bolts. The valve stem is rotated by the handwheel, and the valve stem drives the gate plate to move up through the thread. The gate plate of the valve is covered with rubber as a whole on the outside, and the deformation compensation generated achieves a good sealing effect, overcoming the problems of poor sealing, air leakage and rusting of general gate valves, and more effectively saving installation space.
