    product description


    The types of gate valves can be divided into wedge gate gate valves and parallel gate gate valves according to the configuration of the sealing surface. Wedge gate gate valves can be further divided into: single gate type, double gate type and elastic gate type; Divided into single gate type and double gate type. According to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate must be forced to the valve seat by external force to ensure the tightness of the sealing surface. The gate of the gate valve moves linearly with the valve stem, which is called a lift-rod gate valve (also called a rising-rod gate valve). Usually, there is a trapezoidal thread on the lift rod. Through the nut at the top of the valve and the guide groove on the valve body, the rotary motion is changed into a linear motion, that is, the operating torque is changed into an operating thrust. When the valve is opened, when the lift height of the gate is equal to 1:1 times the diameter of the valve, the fluid channel xx is unobstructed, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a sign, that is, the position where it cannot be opened, as its fully open position. In order to take into account the lock-up phenomenon caused by temperature changes, it is usually opened to the top position, and then back to 1/2-1 turn, as the position of the fully open valve. Therefore, the fully open position of the valve is determined according to the position of the gate (ie the stroke). For some gate valves, the valve stem nut is set on the gate, and the rotation of the handwheel drives the valve stem to rotate, and the gate is lifted. This kind of valve It is called rotary stem gate valve or dark stem gate valve.
