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

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like figure 1 , figure 2 As shown, the self-inflating expansion tank in this embodiment includes a casing 1 and an inflation device 5. The casing 1 has a port, and the casing 1 is provided with a film 2 communicating with the port. The outer wall of the film 2 is connected to the port. An air chamber 11 is formed between the inner walls of the box body 1, and a water storage chamber 21 is formed inside the skin film 2. A detection mechanism 3 for the height of the skin film 2 is provided in the box body 1. One end of the inflatable device 5 forms a water inlet end, and the other end forms a water storage chamber that is connected to the box body. The inflatable end connected to the body 1 is provided with an inflatable one-way valve 57 at the junction of the inflatable end and the casing 1, and the inflator 5 can inflate the air cavit...

Abstract

An expansion tank capable of self-inflating, comprising a tank (1), the tank (1) has a port, characterized in that the tank (1) is provided with a film (2) communicated with the port, the An air cavity (11) is formed between the outer wall of the film (2) and the inner wall of the box body (1), and a water storage chamber (21) is formed inside the film (2), and the box body (1) is provided with a height of the film (2). detection mechanism, the expansion tank also includes an inflation device (5), one end of the inflation device (5) forms a water inlet end, and the other end forms an inflation end connected to the aforementioned box body (1), and the inflation end is connected to the box body ( The connection of 1) is provided with an inflation check valve (57), and the inflation device (5) can inflate the air chamber (11) when the water inlet end has water pressure. 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...
