Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof lamp processing, in particular to a pressure regulating device for explosion-proof lamps. Background Technique

[0002] For the explosion-proof lamp pressure regulating device and explosion-proof lamp with the authorization publication number of "CN103423720A", one end of the movable valve seal is located inside the protective cover, and its open end is located inside the shell. The inner cavity of the movable valve is communicated with the inner cavity of the shell; the elastic member is used to limit the movement of the movable valve in the communication hole. When the pressure inside the shell is relatively high, the movable valve slides towards the outside of the shell, and the pressure relief through hole is communicated with the valve through hole to relieve pressure; after the pressure is relieved, the air pressure inside the shell decreases, and under the elastic force of the elastic member, the movable valve moves towards the inside of the shell, and the pressure relief through hole is misaligned with the valve through hole, thereby stopping the pressure relief. At the same time, the present invention discloses an explosion-proof lamp.

[0003] This device can realize the self-pressure regulation of the lamp, but during the production process of this device, it is necessary to pressurize the inside of the lamp, and the overall production of the lamp is not completed. During the pressure regulation process, it is impossible to directly observe the pressure setting degree. During subsequent use, the internal pressure itself is too high or too low, resulting in the subsequent self-adjustment not being able to reach a good adjustment value, reducing the practicability and applicability of the device. Therefore, the present utility model proposes a new solution. Content of the Utility Model

[0019] Positive pressure explosion-proof is required during the processing and production of explosion-proof lamps, which means that high-pressure gas is filled into the lamp to make the internal air pressure higher than the external air pressure, and the external gas cannot enter the lamp, thereby playing an explosion-proof role. When performing positive pressure explosion-proof, a pressure regulating device needs to be set. The pressure regulating device provided by the utility model is specially used to observe the input gas more intuitively and quickly, and is convenient for pressure regulation. The device needs to be connected to an external battery when in use, which is convenient for checking the generated electricity and timely observing the input pressure. When in use, an electronic control valve can be installed at one end of the air pipe 5, which can close automatically when the pressure is detected to the preset value to ensure the normal operation of the equipment
