Problems solved by technology

Bring great inconvenience to users
At the same time, because the air pressure in the expansion tank is equal to the heating water pressure at all times, it is difficult to find the insufficient air volume in the expansion tank, so the heating pipeline is often operated in a dangerous state

Abstract

An automatic inflation structure of an expansion tank, comprising a tank (1), the tank (1) has a port, characterized in that the tank (1) is provided with a film (2) connected to the port, the film (2) An air cavity (11) is formed between the outer wall and the inner wall of the box body (1), and a water storage cavity (21) is formed inside the film (2), and the box body (1) is provided with a height of the film (2) As for the detection mechanism, the expansion water tank also includes an inflation device (5) and a controller. The invention also discloses a control method for the automatic inflation structure of the expansion tank. By detecting the height of the film, the box is automatically inflated by using water pressure combined with an inflatable device. The air replenishment process is simple, energy-saving and reliable. Bring great convenience to customers.

Description

technical field [0001] The invention relates to a water tank, in particular to an expansion tank applied to a dual-purpose furnace. Background technique [0002] In the prior art, the expansion tank is installed in the waterway system, which is mainly used to alleviate the expansion and contraction of the circulating water in the heating circuit and the domestic water circuit. For related documents, please refer to the Chinese utility model patent "Household Gas Heating Hot Water" with patent number 00214321.6 "Dual-purpose furnace" (the authorized announcement number is CN2424413Y); you can also refer to the Chinese utility model patent "floor water storage type heating / hot water gas dual-purpose furnace" (authorized announcement number is CN201104017YY) whose patent number is ZL200720056386.3. [0003] Due to the micro-leakage of the air cavity in the expansion tank, the gas volume in the expansion tank will decrease after a period of use, and the decrease in the gas volum...
