The utility model includes a valve body, a protective shell is fixedly installed on the top of the valve body by bolts, an exhaust pipe is connected to the right side of the valve body, a mounting block is fixedly installed inside the protective shell, an adjustment seat is arranged inside the protective shell, a limiting rod is arranged inside the valve body and the protective shell, a sealing member is fixedly installed at the bottom of the inner cavity of the valve body, mounting grooves are provided on both sides of the sealing member, and a first rubber pad is fixedly installed inside the mounting groove. The utility model protects the gas tank by the cooperation between the valve body and the protective shell, an exhaust pipe is arranged to guide the gas discharged from the gas tank, and the working pressure of the valve body is adjusted by the cooperation between the mounting block and the adjustment seat. The utility model also solves the problem that the existing safety valve cannot adjust its working pressure as needed.

[0003] The existing safety valve regulating device is not convenient for adjusting the working pressure. Generally, the working pressure of the safety valve is fixed. During use, it needs to be adjusted according to needs. When adjusting the working pressure, the screw is rotated to squeeze the pressure plate against the spring, so that the spring presses the sealing plate, and the spring elastic force is adjusted to adjust the working pressure. When adjusting, repeated tests are required to achieve the required pressure value. The adjustment process is relatively troublesome, which increases the workload and reduces the efficiency of the adjustment. It is also not convenient for assembly and disassembly. Generally, the safety valve and the electromagnetic pressure reducing valve are installed through flanges or threads. When assembling and disassembling, tools are required to disassemble and assemble them. The disassembly and assembly process is relatively troublesome, which increases the workload and reduces the efficiency of assembly and disassembly. In order to solve the above-mentioned problems, we propose an automatic regulating device for the safety valve of the electromagnetic pressure reducing valve. Utility Model Content
