The opening and closing part of the metal seal gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate has two sealing surfaces. The wedge angle of the two sealing surfaces of the most commonly used gate valve varies with the valve parameters, which is usually 50. When the medium temperature is not high, it is 2 ° 52 ‘. Wedge gate valve can be made into a whole, called rigid gate; it can also be made into a small amount of deformation of the gate, in order to improve its process, to make up for the deviation of sealing surface angle in the process of processing. This kind of gate is called elastic gate.

When the metal seal gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed to the seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self sealing. Most gate valves are forced to seal, that is to rely on external force to force the gate to the valve seat to ensure the sealing of the sealing surface.

The gate valve of hard seal gate valve moves along with the stem in a straight line, which is called rising stem gate valve (also known as rising stem gate valve). Generally, there are trapezoidal threads on the lifting rod. Through the nut at the top of the valve and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is changed into the operating thrust.
