ばねを第１流入路に設けて成るガス用安全弁。 A valve hole is provided in the main body pipe, and a sealing valve body that closes the valve hole when a gas flow pressure above a certain level is applied is provided so as to be movable in the gas flow direction, and is located upstream of the gas flow from the valve hole. A valve receiver is provided, and a first spring is provided on the sealing valve element to urge the sealing valve element to move away from the valve hole and come into contact with the valve receiver. A partition pipe is provided so that the valve receiver is attached to the partition pipe, and a first inflow path is provided between the inner surface of the main body pipe and the outer surface of the partition pipe, and the first inflow is established through a communication notch provided on the downstream side of the partition pipe. A second inflow path communicating with the valve hole is provided between the inner surface of the partition pipe and the outer surface of the valve receiver, and the second inflow path and the first inflow path are connected to the upstream side of the partition pipe. The bypass hole is normally located upstream of the first inflow path, and the bypass hole is closed.
A flow rate setting valve body is provided in the first inflow path to allow a certain amount of gas to flow into the inflow path, and is pushed by gas flow pressure above a certain level to close the first inflow path and open a bypass hole, thereby setting the normal flow rate. A second valve body for returning the flow rate setting valve body so that the valve body for setting the flow rate is located on the upstream side of the first inflow path.
A gas safety valve comprising a spring provided in a first inflow path.
