Description

TECHNICAL FIELD

[0002] In many industrial and civil systems, such as heating systems, air conditioning systems, chemical pipeline systems and various closed containers, automatic exhaust valves play a crucial role. They can timely discharge the accumulated gas in the system and ensure the normal operation of the system.

[0003] However, for some complex systems or scenarios that require precise control, it is not enough to just implement the automatic exhaust function. It is also necessary to timely and accurately obtain the exhaust completion signal so that the system can make corresponding responses, such as adjusting operating parameters, performing the next operation, etc. For example, in some highly automated chemical production processes, the discharge of gas in the pipeline directly affects the stability of the entire production process and the quality of the product. If the exhaust completion signal can be accurately obtained, the operation of each link can be better coordinated, and the production efficiency and product qualification rate can be improved.

[0004] Traditional automatic exhaust valves indicate the completion status of exhaust through mechanical structures. For example, the common float-type exhaust valve rises when the water level rises after gas is discharged, and the float rises to the highest position. The completion of exhaust can be determined by observing the position of the float. However, this method can only provide a rough visual indication and cannot achieve remote signal transmission. In some cases where the installation location is not convenient to observe, it is difficult to accurately obtain the exhaust completion signal. SUMMARY
