Automatic exhaust valve of heat exchange unit for government department

Abstract

The invention discloses an automatic exhaust valve of a heat exchange unit for a government department. A shell is included. An installing cover is fixedly arranged at the upper end of the shell through bolts. The installing cover and the shell are connected in a suspension manner. An air outlet is fixedly formed between the installing cover and the shell. A first connecting rod is fixedly arranged on the inner side of the installing cover. A rubber plug is fixedly arranged on the outer side of the first connecting rod. A floating ball is fixedly arranged on the inner side of the shell. The upper end of the floating ball is fixedly connected with the first connecting rod. An installing box is arranged on the inner side of an installing base, a first conductor, a second conductor and a connecting block are arranged on the inner side of the installing box, the first conductor and the second conductor are movably connected with a first limiting rod and a second limiting rod through installing plates, accordingly, memory metal on the inner side of the first limiting rod can be used for controlling the movement of the installing plates, the first conductor and the second conductor are connected, and accordingly air cylinders are controlled.

Description

technical field [0001] The invention relates to the technical field of heat exchange units, in particular to an automatic exhaust valve for heat exchange units used by government agencies. Background technique [0002] The heat exchange unit is composed of a heat exchanger, a temperature control valve group, a drain valve group (when the heat medium is steam), a circulating pump, an electric control cabinet, a base, pipelines, valves, instruments, etc., and can be equipped with expansion tanks, water Treatment equipment, water pump frequency conversion control, temperature control valve, remote communication control, etc. constitute a complete heat exchange station. The heat exchange unit has the advantages of compact structure, reliable operation, simple and intuitive operation, etc., and is the first choice for high-efficiency and energy-saving products. Therefore, in Most of the existing institutions use heat exchange units to supply heat and provide hot water for use. Ho...

[0002] The heat exchange unit is composed of a heat exchanger, a temperature control valve group, a drain valve group (when the heat medium is steam), a circulating pump, an electric control cabinet, a base, pipelines, valves, instruments, etc., and can be equipped with expansion tanks, water Treatment equipment, water pump frequency conversion control, temperature control valve, remote communication control, etc. constitute a complete heat exchange station. The heat exchange unit has the advantages of compact structure, reliable operation, simple and intuitive operation, etc., and is the first choice for high-efficiency and energy-saving products. Therefore, in Most of the existing institutions use heat exchange units to supply heat and provide hot water for use. However, most of the existing heat exchange units have manual exhaust valves when exhausting, which not only affects the heat exchange units. The operation of the heat exchange unit will also affect the use effect of the heat exchange unit, so an automatic exhaust valve is needed to exhaust the heat exchange unit
