Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the safety valve in the prior art is in use, it can only protect against a small range of pressure, but it cannot protect against a sudden increase in pressure, and at the same time it cannot give an alarm in time. Remind the staff that the rated pressure range cannot be adjusted, and it is inconvenient to use, so a pneumatic pipeline safety valve that can fine-tune the rated pressure is proposed

Abstract

The invention belongs to the field of safety valves, particularly relates to an air pressure pipeline safety valve capable of finely adjusting rated pressure, and aims to solve the problems that an existing safety valve cannot play a role in protecting suddenly increased pressure and cannot give an alarm and remind workers in time, and the rated pressure range cannot be adjusted. The pressure regulating valve comprises a first valve body and a second valve body, the bottom of the first valve body and the bottom of the second valve body fixedly communicate with inner cylinders, the bottoms of the two inner cylinders fixedly communicate with the same Y-shaped air inlet pipe, and one side of the first valve body and one side of the second valve body fixedly communicate with air outlet pipes. The device is simple in structure and wide in application range, the sealing performance of the device is achieved through the sealing assembly, the alarm assembly can give an alarm and remind workers in time, the protection assembly can protect the device, the service life of the device is prolonged, and the replacement and maintenance frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to an air pressure pipeline safety valve capable of fine-tuning rated pressure. Background technique [0002] The safety valve is a special valve that the opening and closing parts are in a normally closed state under the action of external force. When the pressure of the medium in the equipment or pipeline rises beyond the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. NOTE The safety valve must be pressure tested before it can be used. [0003] When the existing safety valve is in use, it can only protect against a small r...
