[0002] A pressure reducer is a device that can reduce pressure. It is often used in industry and pipeline systems to control the pressure of fluids or gases in order to protect equipment and pipelines from damage due to excessive pressure. Pressure reducers can be used in welding and cutting technology.

[0003] A pressure reducer for welding and cutting is a device used to control the gas pressure in welding and cutting equipment. It can reduce the high-pressure gas to the required working pressure through the pressure reducing valve to ensure the normal operation of the welding and cutting equipment. A pressure reducer for welding and cutting usually consists of a pressure reducing valve, a pressure gauge and connecting pipes. The pressure reducing valve can adjust the output pressure of the gas as needed, and the pressure gauge is used to display the current output pressure.

[0004] When the existing pressure reducer for welding and cutting is working, high temperature and high pressure will be generated during the welding and cutting process, and the pressure reducer will generate a lot of heat. If the pressure reducer is not dissipated in time, it will cause the equipment to overheat or even damage the equipment. To solve this problem, we propose a pressure reducer for welding and cutting with a protective mechanism. Summary of the invention

The support rod 56 fixed on the surface of the sliding plate 54 moves out of the support frame 51. During the movement of the support rod 56, the pressure plate 571 is resisted to move under the support of spring 2 573. The sliding rod 575 fixed on the surface of the pressure plate 571 drives the slide plate 576 to slide on the surface of the liquid storage frame 574. The circular hole 577 on the surface of the slide plate 576 coincides with the through hole 7, and the coolant in the liquid storage frame 574 can flow into the funnel 578 from the through hole 7. The funnel 578 transmits the coolant into the sponge block 4 to provide heat dissipation protection for the wrapped connecting pipe 3, thereby preventing the pressure reducer 1 from overheating and causing damage to the equipment.

[0027] The surface of the fixed plate 8 is provided with a slide rail 6, and the provision of the slide rail 6 can ensure the stable movement of the moving rod 572 and the pressing plate 571.
