Gate valve refers to the closure (gate) along the channel center line of the vertical direction of the movement of the valve. Gate valve in the pipeline can only be fully open and fully closed cut off, can not be used for adjustment and throttling. Gate valve is a valve with a wide range of use. Generally, cut-off devices with a diameter DN≥ 50mm are selected, and sometimes gate valves are also selected for cut-off devices with a small diameter, Electric stainless steel gate valve has two sealing surfaces, the two sealing surfaces of the more commonly used mode gate valve form a wedge, wedge angle varies with the valve parameters, usually 50, medium temperature is not high for 2 ° 52 '. Wedge gate valve gate can be made into a whole, called a rigid gate; can also be made to produce micro deformation of the gate, in order to improve the process, make up for the sealing surface angle in the process of deviation, this gate is called elastic gate.

When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, the sealing surface of the gate pressure to the other side of the valve seat to ensure the sealing surface of the seal, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on the external force to press the gate to the valve seat to ensure the sealing surface.
The gate of the gate valve with the stem for linear motion together, called the lifting rod gate valve (also known as the open rod gate valve). Usually in the lifting rod on the trapezoidal thread, through the valve products on the top of the nut and the valve body on the guide groove, the rotary motion into a linear motion, that is, the operating torque into the operating thrust.
When the valve is opened, when the gate lift height is equal to 1:1 times the diameter of the plumbing valve, the fluid channel is completely unobstructed, but during operation, this position cannot be monitored. In actual use, the apex of the valve stem is used as a sign, that is, the position that does not move, as its fully open position.
