In industrial application, due to the process system, maintenance personnel is required to regularly drain or exhaust some meters or meter pressure-taking pipelines, even partial process system pipelines are required to drain or exhaust the meters, and the drainage or exhaust of the meters is generally carried out from a meter valve bank. Some meters in industrial applications measure not only high temperature, high pressure media, but also chemical media with high risk of strong acid, strong base, strong radioactivity, etc. At the same time, there may also be a high risk of media around the meter mounting location. This brings inconvenience to the field maintenance personnel to work such as pollution discharge or exhaust of the instrument. Taking a three-waste system of a certain nuclear power station as an example, the instrument or the instrument pipeline of the system is often blocked, and maintenance personnel is required to discharge sewage from the instrument valve group. However, the medium inside the system is generally a medium with stronger radioactivity, and the surrounding environment has higher radioactivity, so that the working risk of the drainage of the instrument or the instrument pipeline is higher. During the overhaul of a unit at a certain time, when maintenance personnel blow off the instrument from the instrument valve group, the radioactive medium in the instrument sampling pipe is sprayed out due to the high internal pressure of the system, so that the workers and a working site are polluted by the radioactive medium. Therefore, it is very important to improve the safety and efficiency of the instrument pollution discharge and exhaust.
At present, an instrument pollution discharge and exhaust device is urgently needed, and the pollution discharge and exhaust work of the instrument can be safely and quickly completed.
