Pressure gauges are common measuring instruments. With the continuous development of the instrument 

industry, pressure gauges have been widely used in various fields such as industrial production.

The pressure gauge can intuitively display the pressure changes of each process link, gain insight into the condition formation in the product or medium process, monitor the safety trends in the production and operation process, and build a rapid and reliable safety guarantee through automatic interlocking or sensing devices , Has played an important role in preventing accidents and ensuring the safety of people and property, and is called the "eye" of safety.

However, in actual production and life, pressure gauges are neglected or used illegally, which brings hidden dangers to safety. The main performance is:

1. The installation and configuration are not standardized. The current regulations have clear requirements for the configuration, installation, use, maintenance, and inspection of pressure gauges. However, during actual assembly, reduce the number of secondary parts or double (multi) meter monitoring locations. The diameter and range of the disk are not suitable for working requirements, and it is used under special conditions such as flammable, explosive, toxic, and corrosive. Special instruments, etc., are prominent in random changes to regulations.

2. Do not pay attention to daily use and maintenance. Inspect and clean it irregularly during use. There is no record of usage, and there are phenomena such as non-return to zero or severe fluctuations of the hands, peeling off of the protective film of the blast hole, corrosion of the dial or broken glass, and uncleaning of the dial.

3. The inspection and verification work is not implemented. The general verification period of the pressure gauge is half a year. Compulsory verification is a legal measure to ensure reliable technical performance of pressure gauges, accurate value transfer, and effective safe production. Because some users do not have a good understanding of the safety function of the pressure gauge, they do not apply for verification in advance, and the phenomenon of exceeding the verification period is very serious. Especially the newly purchased pressure gauge can be installed and used after the verification is qualified, but the first use verification rate of the new meter is still Very low.

Compared with the production system, the pressure gauge is too small, and there is no danger in the pressure gauge itself. However, with the pressure gauge as the main body, the automatic interlocking device, the sensing device, and the protection device as the backing, and the small and subtle perception as the vision, the fortress of safe construction is irreplaceable. "Thousands of miles of embankment collapsed in ant dens." Contempt and neglect of details is a sacrilege of security. As one of the safety accessories, the pressure gauge not only displays a few pressure numbers, it uses clever "eyes" to monitor the slightest "leakage hole", and always guards the door to product safety, personal safety, and environmental safety. Especially when used in dangerous places such as the production, storage, and transportation of flammable, explosive, and toxic substances, stress factors play a key role in preventing catastrophic accidents. The contribution of pressure gauges to safety cannot be underestimated. First of all, the user unit should continuously improve its safety awareness and sense of responsibility, and truly manage and make good use of the characteristics of the pressure gauge to make it play the role of "eyes"; secondly, the testing and verification agency should actively perform the verification of the pressure gauge and downgrade it in time , Discard pressure gauges that do not meet the requirements for use, with accurate values and reliable performance; thirdly, the supervision department must strictly supervise the violations in the use of pressure gauges, and investigate and punish illegal operations and illegal use behaviors in accordance with the law. Let us start from the details, start from the foundation, polish the "eyes" of safety, and jointly build a strong and safe long embankment.
