弁。In a valve box 1, which is provided with an inlet port 10 and a relief port 511, which are connected to and communicate with a boiler, etc., a partition wall 3 is provided which is continuous with the inlet port 10 side and is provided with a valve port 30 with respect to the relief port 11 side. A diaphragm opening/closing valve 4 which opens and closes the valve port 30 according to pressure fluctuations within the pressure sensitive chamber 12 is formed into a partitioned pressure sensitive chamber 12, and a spring 41 acts from the back side of the diaphragm opening/closing valve 4. In the pressure safety valve which is biased towards the closing side by The body 50 of the thermostat 5 is moved in and out of the body 50, and the body 50 of the thermostat 5 is pushed out toward the multi-diaphragm on-off valve 4 by a spring 53 whose spring pressure is stronger than that of the spring 41. 51 is passed through the piston sliding cylinder 43 provided at the center of the diaphragm type on-off valve 4 and protrudes from the back side of the diaphragm type on-off valve 4.
A pressure safety valve characterized in that its tip abuts against a spring support member 42 that supports the spring 41 that biases the pressure safety valve toward the closing side.
