Details:
A gate valve refers to a valve in which the closing member (gate) moves in the vertical direction of the centerline of the passage. The gate valve is mainly used for cutting off in the pipeline.
Gate valve is a kind of valve that is widely used. Generally, it is used for cut-off devices with a diameter of DN ≥ 50mm. Sometimes gate valves are also used for cut-off devices with small diameters. Gate valves have the following advantages: ① Small fluid resistance. ②The external force required for opening and closing is small. ③ The flow direction of the medium is not restricted. ④ When fully open, the sealing surface is less eroded by the working medium than the globe valve. ⑤ The shape is relatively simple, and the casting process is better.
The gate valve also has shortcomings: ①The overall size and opening height are large. Installation requires more space. ② During the opening and closing process, there is relative friction between the sealing surfaces, which is easy to cause scratches. ③The gate valve generally has two sealing surfaces, which adds some difficulties to processing, grinding and maintenance.
According to the structure of the gate valve, the gate valve can be divided into: (1) Parallel gate valve : the sealing surface is parallel to the vertical center line, that is, the gate valve with the two sealing surfaces parallel to each other. In parallel gate valves , the structure with thrust wedge is often common, that is, there is a double-sided thrust wedge between the two gates. This gate valve is suitable for low-pressure, medium- and small-diameter (DN40-300mm) gate valves. There are also springs between the two gates, the springs can generate a pre-tightening force, which is beneficial to the sealing of the gates. (2) Wedge gate valve: the sealing surface is at a certain angle to the vertical centerline, that is, the gate valve with the two sealing surfaces forming a wedge shape. The inclination angle of the sealing surface is generally 2°52´, 3°30´, 5°, 8°, 10°, etc. The size of the angle mainly depends on the temperature of the medium. Generally, the higher the working temperature, the larger the angle should be taken to reduce the possibility of wedging when the temperature changes.
