Claims

[Scope of utility model registration request]

A valve chamber that communicates with the water flow chamber for water flow on both sides of the valve box and into which the valve body enters when the valve is opened in a direction perpendicular to the center line of the water port, and an auxiliary chamber located at a position symmetrical thereto, are provided inside the valve box. The valve body is provided with a valve body that closes the water passage ports on both sides, and a slide member that is always located in the water passage chamber and the auxiliary chamber and moves to the valve chamber and the water passage chamber when necessary, and the valve body is a valve for opening and closing the water passage ports. The rod is movable from the water passage chamber to the valve chamber, and the slide member includes a portion that is in close contact with the inner end surface of the water passage hole, an opening that communicates with the water passage hole, and a portion that is fixed to this opening and matches the valve seat of the valve body. In place of the opening, a through hole communicating with the water inlet, a close contact portion to the inner end surface of the water inlet, and a movable auxiliary valve stem are provided, and normally the slide member is in the water flow chamber. The valve seat of the valve body is brought into close contact with the valve seat of the opening that is located in the sub-chamber and communicates with the water inlets on both sides to prevent water from flowing through the water inlets on both sides, and when necessary, the valve body is moved to the valve chamber and the water inlet is opened by a sliding member. A gate valve characterized in that water flows through openings with through holes instead of openings on both sides, and watertightness is maintained between the water ports on both sides, the through hole, and the valve chamber by the close contact between the end surfaces of the water ports and the end surfaces of the through hole. .
