するものである。This invention has been made based on the above-mentioned disadvantages, and its purpose is to cause the fluid force flowing through the valve chamber to vibrate the valve body when the valve is opened, thereby causing impact noise on the valve body and valve seat, and causing damage to the thyroid holder. To provide a gate valve that prevents damage to parts.
以下、この発明の実施例を第３図〜第５図について説明

弁室部の拡大図に相当する図で、第３図、第４図は閉弁
状態の図であり、第５図は開弁状態の図である。In the figures, parts of the field are designated by the same reference numerals as in FIGS. 1 and 2. Figures 3 to 5 are enlarged views of the valve chamber in Figures 1 and 2, with Figures 3 and 4 showing the valve in the closed state, and Figure 5 showing the valve in the open state. FIG.

けられている。A valve seat 6.6' is fixed to the valve holes 5, 5' of the valve chamber 4, and a valve body 7 is interposed between the valve seats 6.6' and an annular holder 8.
It is connected to the valve stem 9 via the section. A protruding piece 11 is attached to the lower end of the valve body 7, and this protruding piece 11 is attached to the lower end of the valve body 7.
A contact groove 12.12' in which the valve seat 1 rests is provided in the valve seat 6, 6'.
この発明は上記構成であるから、開弁動作時には接触溝

６′に固定する。したがって、弁室４内を流通する流体
力が弁体７に作用して弁体７を振動させ九す、弁体７の
衝撃音を発生させたりすることが避けられる。Since the present invention has the above configuration, the protruding piece 11 comes into contact with the contact groove portion 12.12' during the valve opening operation, and the valve body 7f valve seat 6.
Fix it at 6'. Therefore, it is possible to prevent the fluid force flowing in the valve chamber 4 from acting on the valve body 7, causing the valve body 7 to vibrate, and generating impact noise of the valve body 7.
尚、突起片１１と接触溝部１２．１２’の接触面はテー
パ状に形成しておくことによって接触面が多少曝耗して
も弁体７の固定力を持続することができる。Note that by forming the contact surface between the projection piece 11 and the contact groove portion 12.12' in a tapered shape, the fixing force of the valve body 7 can be maintained even if the contact surface is worn out to some extent.

ができる。As explained above, according to the present invention, when the valve is opened, the projection piece attached to the valve body comes into contact with the contact groove of the valve seat and fixes the valve body, thereby preventing the generation of vibrations, impact noise, etc. of the valve body. It can be avoided.
