ABSTRACT:
The gate valve of the invention may be disposed in a flow path through which a hydrocarbon gas produced by thermal decomposition, or an exhaust gas passes. In the gate valve, ring-like valve body seats 5A, 5B, and ring-like retainers 14 and ring-like spacers 17 which are disposed on the both sides of the valve body seats are fitted into ring-like grooves 20 formed on faces of ring-like seal boxes 7 which oppose a sliding valve disc 2, in such a manner that the valve body seats, retainers and spacers are disabled from moving in a radial direction. Ring-like convex portions 21 formed on the ring-like seal boxes 7 are fitted into ring-like concave portions 22 on a valve body 1, in such a manner that the ring-like convex portions 21 are disabled from moving in a radial direction. Even when the sliding valve disc 2 moves, the ring-like valve body seats 5A, 5B, and the ring-like seal boxes 7 do not move. Accordingly, the lowering of the sealing properties due to the abrasion of ring-like seal members 9, the ingress of foreign substances into the spaces of housing second springs 11, and the fluid leakage into the space of the valve body 1 are prevented from occurring.
