The opening and closing parts of the fire gate valve are the gate plates. The movement direction of the gate plates is perpendicular to the direction of the fluid. The gate valves can only be opened and closed completely, and can not be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedge-shaped, wedge-shaped angles which vary with valve parameters, usually 50, medium temperature is not high when 2 degree 52'. Wedge gate valves can be made into a whole, called a rigid gate; can also be made into a small deformation of the gate, to improve its workmanship, to compensate for the angle of the sealing surface in the processing of the deviation, which is called elastic gate. Fire gate valves can be divided into wedge gate valves and parallel gate valves according to the type of sealing surface. Wedge gate valves can be divided into single gate pole type, double gate type and elastic gate type. Parallel gate valves can be divided into single gate type and double gate type.
According to the screw thread position of the stem, it can be divided into two kinds: the open gate valve and the hidden pole gate valve.
