ABSTRACT:
A coupling frame formed at a connecting portion on an out-port side of a first safety valve, and a coupling frame formed at a connecting portion on an in-port side of a second safety valve are brought into contact with each other, directly or by causing a plate-shaped member to intervene in between. Coupling projections, facing each other, formed in the coupling frame of both the safety valves are sandwiched between a pair of latch portions of a latch member, and a pair of latch members facing each other, are mutually drawn by tightening rod members. The coupling projections of both the safety valves are thereby pressed in a mutually approaching direction with the latch portions of each of both the latch members, and thereby both the safety valves are coupled.
