規制させるべく構成した弁の構造に関する。[Detailed description of the invention] The present invention relates to a valve structure such as a slide valve that opens and closes a valve body by moving a valve body operating shaft in the axial direction. A metal packing ring and a cylindrical first retaining member are interposed between the operating shaft and the bearing, and an elastic packing ring and a first retaining member are interposed between the operating shaft and the first retaining member. The present invention relates to a valve structure in which a cylindrical second retaining member is interposed so that the insertion side stroke end of the operating shaft is regulated by the action of a contact portion connected to the shaft.

期通り維持する事ができなくなるものであった。In order to regulate the insertion side stroke end of the valve body operating shaft into the valve body and to determine the closed position of the valve body, conventionally, as shown in FIG. A stopper 29 is integrally connected to the bearing part 10 by a bolt 20 to regulate the insertion side stroke end of the valve body operating shaft 6. was located far away from the stopper fixing support bolts 20, so the regulating force acts as concentrated stress between the two-point support members provided by the bolts 20. The stopper itself is bent or the bolt 20 is bent to the left, and the stroke end regulation position changes, making it impossible to maintain the closed position of the valve body as expected.

すべく構成しである事を特徴とする。The purpose of the present invention is to eliminate such drawbacks with an extremely simple structural improvement. It is characterized in that it is configured such that the abutting portion is made to protrude from a flange for attaching a retainer of the second retainer member and come into contact with the protruding end of the protrusion.

だけで、全体をコンパクトに構成する事ができた。In other words, the line of force of the impact regulating force when regulating the stroke end is passed through the cylindrical part of the first retaining member, which is strong against total bending stress, and the metal packing ring, which is strong against compressive stress, so that it is not deflected. The stroke end can be maintained as expected over a long period of time, and the entire structure can be made compact by simply extending a portion of the cylindrical member to form a protrusion, or simply adding a protrusion with a simple structure.
次に、本考案実施の態様を例示的に基づいて詳述する。Next, embodiments of the present invention will be described in detail based on examples.
