Description

Technical Field

[0001] The utility model belongs to the technical field of pressure gauges and relates to a fluid medium pressure gauge with a moisture-proof function. Background Art

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate a pressure higher than the ambient pressure. It is widely used and is almost found in all industrial processes and scientific research fields. It can be seen everywhere in the fields of thermal pipe networks, oil and gas transmission, water supply and gas supply systems, vehicle repair and maintenance shops, etc. Fluid medium refers to a method of converting energy using fluid as a working medium. A fluid medium pressure gauge is a pressure gauge that measures the pressure value inside the fluid when the fluid converts energy. Patent No. CN214502751U discloses a fluid medium pressure gauge with a buffer structure, including a protective shell and a main body located inside the protective shell. The protective shell is connected to the main body through a buffer component inside the protective shell. The buffer component includes four inner extension seats symmetrically distributed on both sides of the protective shell and vertically embedded in the top wall and bottom wall inside the protective shell. One side of the main body is fixedly connected to a protruding cover, one side of the main body is inlaid with a transparent cover, and the inner wall of the main body is rotatably connected to a rotating shaft, and a pointer is connected to the rotating shaft. The bottom wall of the main body is installed with a mounting joint that passes through the protective shell. The main body and the inner side of the protruding cover are provided with a self-cleaning mechanism, and the self-cleaning mechanism includes a driving component and a cleaning component. The fluid medium pressure gauge with a buffer structure can prevent the appearance of water mist, small water drops and the like inside the transparent cover from affecting the viewing of the pointer by personnel, thereby making the pressure gauge more convenient to use in various environments.

[0003] The disadvantage of the pressure gauge disclosed above is that since the pressure gauge measures fluid pressure in a relatively humid environment, it does not have a good moisture-proof effect. Therefore, we design a fluid medium pressure gauge with moisture-proof function. Summary of the invention
