この発明はボイラ、化学プランＩ・その他の設備に用い
られる仕切弁に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a gate valve used in boilers, chemical plan I, and other equipment.

操作が困難となるとノ（に、胴部、弁体などに過大な応
力が発生する。(Prior Art) As is well known, a sensible PI pressure is generated in a gate valve connected to a high-temperature steam pipe system. This is because when the valve ``y1'' dries up during the warming up of the /H tracheal system, the condensate that has accumulated and been trapped in the body of the valve box evaporates, creating an abnormally high pressure within the body.This pressure Therefore, if it becomes difficult to open the valve, excessive stress is generated in the body, valve body, etc.

ではない。A wedge-shaped valve, especially a flexible valve body, has a high sealing performance at the valve seat, but in order to avoid the abnormal pressure increase mentioned in I-.
I try not to give up completely when the valve is closed. In other words, without forcing the valve upward, the valve seat on the exit (1 side) is brought into close contact with the valve seat on the valve body to maintain a seal, and
17 on both sides to prevent electrodeposition on both valve seats. Therefore, the body communicates with the valve box entry [=1 side, and no abnormal pressure occurs. However, this sacrifices the high sealing performance of the wedge-shaped valve body, which is not desirable.

る。In addition, a bypass valve is provided in the valve box or piping to bypass the valve at the time of starting operation of equipment such as a boiler, for warming up equipment, piping, etc., or for pressure balance after the valve surface. This bypass valve requires a separate valve and bypass housing, which is not only uneconomical but also requires extra space to install the bypass valve.

するものである。(Purpose of the invention) This invention is tidy! This was done in order to solve the problem described in -1- in the 11 valve, and even if the 1 cut valve 1' is completely closed, abnormal pressure 4 will not occur. The purpose of this invention is to provide a gate valve that does not require the provision of a gate valve.

られている。(Structure of the Invention) In the valve housing JM equipped with the integral wedge-shaped valve housing of the present invention, the gate valve body has a valve chamber that opens to the first portion of the gate valve IF, and the valve chamber and the inlet side of the gate valve box are connected to each other. It is equipped with a flow passage on the artificial side that communicates with the valve chamber, and a flow passage on the side that opens to the bottom of the valve chamber, and a flow passage that communicates with the outlet [1 side] of the 5F box. A seat is provided at the lower end of the gate valve body so that a starter valve body is accommodated in the valve chamber.

弁体を介１．て弁体により押し下げられる。(Function) When closing the J-valve, when the gate valve body is lowered one step by a rigid device or by manual operation, the gate valve body is moved through the 11th valve body to the 1st valve body. and is pushed down by the valve body.

れが生ずることはない。At this time, the gate valve body is pushed down until a wedge action is exerted between the gate valve fr body and the valve seat, and the partition 1 is closed. At the same time, the 11th valve body in the 1st valve body is pressed against the 11th valve seat by the valve stem. Close the L valve as well. Due to the wedge action, the valve seat of the gate valve body is pressed against the valve body valve seat at the inlet [1] and outlet [1], thus exhibiting high sealing performance. That is, even if the differential pressure between the inlet 11 side and the outlet 1 side of the gate valve is low, no leakage occurs between the valve body valve seat and the valve body valve seat.

If the voltage is +, the current will be released due to warming up of equipment, etc. At this time, the condensate that has become steam in the body leaks to the valve body 1 side through the gap between the peripheral surface of the valve chamber and the outer periphery of the valve body, and through the flow path on the 1 side. Therefore, the pressure in the torso will not rise above A.

流出する。In the case of pressure balance before and after the gate valve or warming amplifier of the device, pull the valve body slightly to open only the stop valve. Fluid such as steam flows out from the population side of the valve box to the side of the valve box 11j via the population side flow path, the chamber and the outlet side flow path.
