The gate plate of the wedge gate valve can be made into a whole, namely a rigid gate plate; the gate plate can also be made into a gate plate capable of generating micro deformation so as to improve the manufacturability of the gate plate and compensate the deviation of the angle of the sealing surface in the machining process, and the gate plate is called an elastic gate plate.
The elastic seat seal gate valve is also called a lifting rod gate valve (also called an open rod gate valve). Usually, the lifting rod is provided with trapezoidal threads, and the rotating motion is changed into the linear motion, namely the operation torque is changed into the operation thrust force through a nut at the top end of the valve and a guide groove on the valve body. When the valve is opened, when the lifting height of the gate plate is equal to 1 of the drift diameter of the valve: at 1 time, the passage of fluid is completely clear, but in operation, this position is not monitored. In actual use, the vertex of the valve rod is used as a mark, namely, the opening and closing position is used as the full opening position. To account for the occurrence of lock-up due to temperature changes, the valve was opened to the top position and then reversed 1/2-1 cycles to assume the fully open valve position. Thus, the fully open position of the valve is determined by the position (i.e., stroke) of the gate.
At present, more traditional elastic seat seal gate valves have poor high-temperature resistance, poor sealing performance and inflexible operation and control, and the problems need to be improved on traditional equipment, so that the high-temperature resistant elastic seat seal gate valves with opening degree indication locking are proposed.
