Claims

[Scope of utility model registration request]

It has an upstream passage and a downstream passage on both sides, a stepped part for storing a part of the valve seat inside each of these upstream passage and downstream passage, and a body part for storing a part of the valve seat in the lower part of the central part. , a main body provided with a valve stem storage part whose upper end is open at the upper part of the central part, a cylindrical part having a through hole corresponding to an upstream passage and a downstream passage of the main body, and a plate extending in a direction perpendicular to the central axis of this cylindrical part. a plate-shaped valve body having two valve seats that face each other in parallel, and a plate-shaped valve body that slides between the valve seats and has a through hole that corresponds to the through hole of the valve seat, and a closing part; , a gate valve comprising a spring member that presses the valve seat against the valve body; a small guide hole formed in the body of the main body that communicates the cavity with the upstream passage; and a small guide hole that communicates the cavity with the downstream passage; A gate valve characterized in that a guide hole is formed to seal between the bottom of the body and the cavity of the body.
