Product Description

Related recommendation: Flange open rod gate valve:




     The concealed rod gate valve is also called the rotary rod gate valve (also known as the concealed rod wedge gate valve).The valve stem nut is arranged on the gate, and the handwheel rotates to drive the valve stem to rotate, so that the gate is raised. Usually, there is a trapezoidal thread at the bottom of the valve stem. Through the thread at the bottom of the valve and the guide groove on the disc, the rotational movement is turned into linear motion, that is, the operating torque is turned into operating thrust.When the valve is opened, when the lifting height of the gate is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but during operation, this position cannot be monitored.In actual use, the apex of the stem is used as a sign, that is, the position where it cannot be opened, as its fully open position.In order to consider the locking phenomenon of temperature changes, it is usually at the position of opening to the apex, and then rewind 1/2~1 circle, as the position of the fully open valve.Therefore, the fully open position of the valve is determined by the position of the gate (that is, the stroke).


   The lifting screw of the dark rod flange gate valve rotates only without moving up and down. What is exposed is only a rod. The nut is fixed to the gate. The gate is raised by the rotation of the screw. There is no visible door frame; the lifting screw of the open rod flange gate valve is exposed, the nut is close to the handwheel and is fixed (neither rotating nor moving axially), the gate is raised by rotating the screw, the screw and the gate have only relative rotational movement without relative axial displacement, and the appearance is a door-shaped bracket.
