Claims

[Scope of utility model registration request]

A pair of upper and lower valve body seats are attached to the seal box while being prevented from coming off by the seat ring, and at least the upper valve body seat of these valve body seats is biased downward to move from the fully open position to the fully closed position. It slides into contact with both the upper and lower surfaces of the sliding valve body that moves back and forth, holds both ends of the sliding valve body in the width direction and guides the movement, and also holds both ends in each of the fully open position and fully closed position. A guide for a valve body in a horizontally mounted gate valve, characterized in that the guide member is provided with a guide member which is floatingly supported on the valve body via a spring having a reaction force equal to the load of the sliding valve body. .
