Abstract

PURPOSE: To obtain highly accurate sealing effect by using a thin plate on the sealed face of a gate valve.
CONSTITUTION: When sending a high-pressure fluid into the inlet 26 of a connecting bar 4 under the condition that gates 2 and 3 are closed, the fluid flows from a hollow 7 into the hole 8 of an intermediate plate 10 and then goes out from outlets 9 and 9' on both sides on valve bodies 14 and 14' sides, where the high-pressure fluid pushs the valve bodies 14 and 14' toward outside against a spring 15 and its part goes from the introducing hole 21 of the valve bodies 14 and 14' into a chamber 22 to press on a thin plate 17. As a result, the thin plate 17 pressed by the fluid is pressed on each sealed face 18 to make the sealing degree of the sealed face exact. In short, even when the sealed face 18 is uneven and its parallel degree and planeness are somewhat great, the thin plate 17 can closely adhere to the sealed face 18 by the pressure of the fluid.
