Description

Technical Field

[0001] This utility model relates to the field of exhaust device technology, and in particular to a remote control exhaust device. Background Technology

[0002] The water pumps in the heat exchange platform use superheated water as the heating medium. During operation, gas can easily accumulate in the pipelines. Failure to vent the gas promptly can lead to safety hazards, necessitating frequent venting operations. Due to the significant distance between the heat exchange platform and the main control room, the current venting method requires operators to manually activate the vent valves by traveling to and from the site. Furthermore, a single venting operation often fails to completely remove the gas from the pipelines, requiring multiple trips by the operator, reducing work efficiency and increasing workload. Additionally, existing vent valves are typically connected to the venting pipeline via flanges, which are fixed to the valve body. This necessitates the use of expanders during disassembly and assembly, making the process cumbersome and maintenance inconvenient. Utility Model Content
