<p><P>PROBLEM TO BE SOLVED: To provide a composite safety valve having two safety valves which eliminates the waste of discarding a safety valve having no trouble by replacing only the failed safety valve when one of the safety valves has a trouble. <P>SOLUTION: Contact surfaces 79 are individually formed on an out-port side of a first safety valve 10A and on an in-port side of a second safety valve 10B. A plate-like member 51 containing a communication hole 53 of a connector 50 are sandwiched between the contact surfaces. Locking projections 81 provided to the opposite ends to the contact surfaces 79 are detachably connected by the detachable connector 50 for fastening the projections in a direction of approaching each other. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
