ルバルブ。 The inlet side valve seat is biased against the valve body by a spring, and a packing is interposed between the outlet side valve seat and the inner wall surface of the valve casing so that the outlet side valve seat can slide airtightly. In this case, the outlet side valve seat is made of a soft material such as synthetic resin, and the outlet side corner of the outer periphery is formed into a cylindrical surface parallel to the axis of the valve seat, and this cylindrical surface is expanded to the valve body side. A ball valve that is formed into a shape consisting of rough tapered surfaces and has an O-ring packing arranged in an annular space between both surfaces and the inner wall surface of the valve casing.
