Background
The soft seal gate valve opening and closing piece adopts a gate valve, and a gate plate is usually formed by casting a gate plate iron core and lining rubber. The working state can only be fully opened or fully closed. The valve rod is provided with trapezoidal threads, and the rotary motion is changed into linear motion through the nut in the middle of the flashboard, namely, the operation torque is changed into operation thrust. When the valve is opened, the passage of fluid is completely clear when the gate lift height is equal to 1 times the valve path, but this position is not monitored during operation.
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.
Normally, under the closed state of the soft seal gate valve, the flashboard is easily subjected to the acting force from the water pressure difference of the single side of the pipeline, so that the flashboard excessively extrudes the rubber of the sealing surface of the flashboard along the single side of the water flow direction for a long time, the bottom of the flashboard tilts a certain angle along the water flow direction, and the conditions of flashboard deformation and rubber necrosis of the sealing surface of the flashboard occur.
