General industrial disc gate valve

General industrial full-bore disc gate valve consists of half-bodies item #1 and item #2, rigidly fastened to each other through the intermediate ring item #10, between which there is a disk gate (gate) item #4. Turning the gate item #4 is carried out by the pinion shaft item #3, which engages with the toothed sector of the gate. When turning the handle item #8 gate item #4 rotates around the axis item #7 and thus opens or closes the through hole of the valve. In this case, the pointer item #5 extends or slides into the indicator housing item #11, ensuring the coincidence of the end of the pointer item #5 with a corresponding inscription on the indicator body item #11. The transfer of the gate from the open position to the closed position corresponds to 1.5-2.5 revolutions of the pinion shaft (from stop to stop). The gate seal is provided by two seats item #9 installed in half-cases item #1 and item #2, pressed against the gate surface by spring elements.
