How to distinguish between wedge gate valve and parallel gate valve
Gate Valve The internal structure of the wedge type and the parallel type is different. The wedge type means that the structure is a wedge type, that is, an oblique sealing structure. The parallel type is called a flat gate valve. Its characteristic gate is vertical, and there is a diversion hole in the middle of the gate. The switch is very portable, the pipe and the diameter are full diameter, so it is called the parallel type. From the appearance point of view, the parallel gate valve is shorter than the wedge gate valve, but the height is longer. There is a long dust cover on the parallel handwheel, which plays a role of dust blocking and indicating. There is no wedge. The sealing surface of the wedge gate valve is at a certain angle with the pipeline axis, that is, the two sealing surfaces are wedge-shaped gate valves. The size of the wedge's frequency slope angle mainly depends on the temperature of the medium. Generally, the higher the working temperature, the larger the a...
