Abstract
The utility model relates to an expansion tank whose inner container can be changed, which comprises a metal tube body, wherein an automatic gas charging valve which charges gas to the metal tube body is arranged on the lower portion of the metal tube body, and an changeable inner container is arranged on the opening on the upper portion of the metal tube body in a detachable mode. The expansion tank is assembled through adopting a detachable model between the inner container and the metal tube body, and the inner container is led to reach the changeable purpose, therein if the inner container is broken in the process of using, the inner container is only needed taking from the metal tube body, and then the inner container is changed, and the metal tube body of the expansion tank can be repeatedly used, thereby lowering production cost. The expansion tank has the advantages of novel and simple structure and strong practicability, which can be widely used in an air-conditioning air-cooled cold (hot) water unit and a chilled water cold (hot) water unit system.
Description
Technical field
The utility model relates to a kind of replaceable liner type expansion drum, and it is applicable to the field that need keep-up pressure when a certain amount of water, refers in particular to be applicable in air-conditioning air-cooled cold (heat) water unit, water-cooled cold (heat) the water machine set system.
Background technology
Expansion drum is that China is a kind of level pressure equipment in the stream in air-conditioning system, heating in recent years, it plays level pressure and holds expansion in this system water, and the assurance system normally moves; At present, existing expansion drum generally comprises metal can and inner bag, is to be inseparable structure between this inner bag and this metal can wherein, so need inner bag and metal can are changed in the lump behind gallbladder break in the expansion drum, so make its cost higher, be unfavorable for market development.
The utility model content
The utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide a kind of replaceable liner type expansion drum, and it can realize that the metal cylinder of expansion drum repeats repeatedly to use, thereby reduces use cost.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of replaceable liner type expansion drum comprises a metal cylinder, and this metal cylinder bottom is provided with an automatic charge valve to the metal cylinder inflation, and opening part detachably is mounted with a removable inner bag above this metal cylinder.
Be connected by flange between above-mentioned inner bag and the metal cylinder, wherein this inner bag is fixed between metal cylinder and the flange by screw.
Above-mentioned inner bag is that elastomeric material is made.
The utility model compared with prior art, if its advantage is interior gallbladder break in the use, only need former inner bag is taken off from metal cylinder, newer inner bag is changed, so the metal cylinder of realizing expansion drum can repeat repeatedly to use, thereby reduces use cost.The utility model novel structure, simple, practical.
Description of drawings
Fig. 1 is the utility model decomposition texture schematic diagram;
Fig. 2 is the utility model assembled state schematic diagram;
Fig. 3 is the utility model assembling structure schematic diagram.
The drawing reference numeral explanation:
1, metal cylinder 11, automatic charge valve
2, inner bag
3, flange
4, screw
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
See also Fig. 1～shown in Figure 3, a kind of replaceable liner type expansion drum comprises a metal cylinder, inner bag and flange, wherein:
The bottom of this metal cylinder 1 is provided with an automatic charge valve 11, so that inflate in metal cylinder 1.
The above-mentioned assembly of inner bag 2 sealing and fixing promptly being finished the utility model expansion drum on metal cylinder 1 by flange 3, if its in use inner bag 2 break, only need unclamp the screw 4 that flange 3 is connected with metal cylinder 1, inner bag 2 taking-ups are changed, charge into the gas of certain pressure then from automatic charge valve 11, just can continue to use; As for the operation principle of expansion drum,, promptly do not add to give at this and give unnecessary details because of it is existing conventional techniques.
The utility model design focal point is to adopt between inner bag and the metal cylinder dismantled and assembled mode to carry out assembly, make inner bag reach replaceable purpose, if so interior gallbladder break in the use, only need inner bag is taken off from metal cylinder, again inner bag is changed, so the metal cylinder of realizing expansion drum can repeat repeatedly to use, thereby reduces use cost.
The above, it only is the preferred embodiment of a kind of replaceable liner type expansion drum of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
Claims (3)
