Abstract

PURPOSE: To eliminate the necessity for disassembling the overall unit of a valve, by removably inserting a seal member into the hollowed part in the side of a valve body and replacing the seal member when a contact seat surface of the valve body is damaged.
CONSTITUTION: A hollowed part 16 is provided in one of the valve seats 13, 14 equipped in a flow inlet 2 and flow outlet 3 of a valve cage 1, and a piece 17 of seal member is removably inserted into said hollowed part 16. When a contact seal surface of the piece 17 is damaged by wearing and its sealing effect is lost, a valve body 15 is lifted, and then the valve seats 13, 14 are removed from the valve cage 1. Then a bolt is screwed into a screw hole 18 provided in the valve body 15, thus the piece 17 can be easily removed from the hollowed part 16 of the valve body. In this way, since the piece can be easily replaced with a new one, disassembly of the overall unit of the valve is not required.
