Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as 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 ca...

The invention discloses an expansion water tank capable of being automatically inflated. The expansion water tank capable of being automatically inflated comprises a tank body (1), the tank body (1) is provided with a port. The expansion water tank is characterized in that a leather film (2) communicating with the port is arranged in the tank body (1), an air cavity (11) is formed between the outer wall of the leather film (2) and the inner wall of the tank body (1), a water storage cavity (21) is formed inside the leather film (2), and a leather film (2) height detection mechanism is arrangedin the tank body (1). The expansion water tank further comprises an air inflating device (5), a water inlet end is formed at one end of the air inflating device (5), an air inflating end connected with the tank body (1) is formed at the other end of the air inflating device (5), an air inflating one-way valve (57) is arranged at the joint between the air inflating end and the tank body (1), and the air inflating device (5) can inflate the air cavity (11) under the state that water pressure exists at the water inlet end. According to the expansion water tank, by detecting the height of the leather film, the tank body is automatically inflated by using water pressure in combination with the air inflating device, the air supplementing process is simple, energy-saving and reliable, and greatconvenience is brought 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...
