弁することができる。(Function) The valve mechanism of the present invention configured as described above has the following functions. That is, although the plate-shaped valve of the present invention is installed with a small gap between the valve seat surface and the valve seat surface, normally, the plate-shaped valve is pressed against the valve seat surface by positive pressure or negative pressure to form a sealing valve. When a pressure opposite to the above pressure is applied, the plate valve opens easily from the valve seat surface due to the restoring force of the plate valve, which is installed with a small gap from the valve seat surface. be able to.
又、本考案の弁機構が休止中は板状弁が弁座面
