That Is, The Wedge Gate Valve Is Called A Wedge Gate Valve, And The Parallel Gate Valve Is Called A Flat Gate Valve.

According to the structure classification, it can be divided into two kinds of wedge gate valves and parallel gate valves.
The plate width means that the sealing surface is parallel to the vertical center line, so the valve body is parallel to the sealing surface on the ram. This kind of smell is the most common double smell plate, in order to close the body and the ram two sealing surface contact tight, often used in the two ram with double-sided thrust wedge. Most of them are used in low-pressure pipelines such as small pipelines. Parallel gate valves with single gate plates are also available but very rare.
Wedge gate valve is the sealing surface and vertical center line at a certain Angle, that is, the two sealing surfaces into wedge-shaped smell valves. Wedge gate valves are available in single and double plates. The advantage of double ram type is that it is sealed and the accuracy of the Angle is low, the temperature change is not easy to make the ram open, and the sealing surface wear can be compensated by gaskets. The disadvantage is that the structure is complex, easy to stick in the dry medium, and the main thing is that the ram is easy to fall off after the upper and lower baffles are corroded for a long time.
