Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust, and in particular relates to an exhaust device that can be used for a water supply pipeline. Background Art

[0002] The water supply system from the insulated water tank to the deaerator is an important part of the boiler water supply. The insulated water tank is mainly used to recover the condensed water of the air conditioning system and the waste heat of the boiler, increase the inlet water temperature of the deaerator, and thus improve the thermal efficiency of the boiler. The deaerator reduces the dissolved oxygen content of the boiler inlet water to prevent the occurrence of boiler corrosion.

[0003] In actual operation, the water supply system from the insulated water tank to the deaerator has air entering the pipes and water pumps due to corrosion and aging of the pipe connection parts, which not only affects the normal operation of the water pump, but also causes damage to the water pump if not discovered in time. On the other hand, during the troubleshooting process, due to defects in the pipe installation, some air often remains high in the pipe and is difficult to be completely discharged. The discharge of air in the water pump not only takes a long time, affecting the stable water supply of the boiler, but also can only discharge hot water to the ground or the water receiving frame, which increases labor intensity and further increases the waste of heat energy and water resources. For this reason, there is an urgent need for a deaerator water supply pipe exhaust device that can realize automatic exhaust while also realizing real-time monitoring and early warning of water pressure and water supply system failures.
