Description

Technical Field

[0001] This utility model relates to the field of vacuum gauge technology, specifically to an easy-to-clean vacuum gauge device. Background Technology

[0002] A vacuum gauge is an instrument used to measure vacuum or air pressure. It accurately measures the degree of vacuum by observing the changes in physical effects under different air pressures. In the steelmaking industry, vacuum gauges are mainly used to monitor the vacuum status of equipment in real time to prevent metals from reacting with oxygen, nitrogen, and other gases in the air during the smelting process, thereby improving the purity and performance of the materials.

[0003] Currently, some existing vacuum gauges, due to the harsh operating environment, experience a significant drop in vacuum level after about two months of use because the filaments inside the gauge cavity accumulate severe dust, leading to gauge failure and eventual scrapping. This results in a short service life, requiring repeated replacements of new vacuum gauges, increasing equipment spare parts costs and production processing costs. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-clean device for vacuum gauges, so as to solve the problem of dust accumulation in the filaments of vacuum gauges affecting the detection effect and service life.

[0027] Working Principle: During use, the pressure gauge tube 33 and the electronic component housing 31 are connected and fixed by the fixing clip 32. A filter screen is installed at one end of the pressure gauge tube 33, and the filament is inside it. The pressure gauge tube 33 cannot be disassembled. The electronic component housing 31 contains a circuit board, which is connected to the crystal head and connecting wire through the connecting slot 6. The vacuum level can be monitored in real time on the computer display. The pressure gauge tube 33 and the electronic component housing 31 can be separated by using the fixing clip 32. A hole is drilled in the non-removable filter screen with a 2.0 drill bit. Then, the filament inside the pressure gauge tube 33 is cleaned with anhydrous alcohol, dried, and reused. The effect can reach the performance of a new vacuum gauge. In later equipment maintenance, the internal parts can be repeatedly cleaned to reduce the possibility of contaminants causing sensor reading drift or inaccuracy. Cleaning can improve the accuracy of vacuum readings and extend the lifespan of the vacuum gauge. Its service life is extended, and the operating cost is reduced. The support rod 9 is supported and fixed by the arc plate 2, the fixing plate 1, and the support frame 10. The shell cover 41 is moved by pulling the handle 7. Then, under the continuous fixation of the connecting block 42, the two positioning frames 43 rotate under the support of the support rod 9, realizing the flipping of the shell cover 41. One side of the shell cover 41 contacts the end cover 5, covering the connecting groove 6. The two fixing bolts 14 are respectively passed through the through grooves 13 of the two sets of second fixing blocks 12 and first fixing blocks 11, and the first fixing blocks 11 and second fixing blocks 12 are fixed by nuts 15 to fix the position of the shell cover 41, effectively preventing the shell cover 41 from shifting. When the connecting groove 6 is not in use, the shell cover 41 covers the connecting groove 6, effectively preventing dust from accumulating inside the connecting groove 6, reducing the cleaning burden, and enhancing practicality.
