Abstract
The utility model belongs to the technical field of the technique of hanging stove and specifically relates to a hanging is expansion tank for stove is related to, include the left and right shell of oval -shaped, left and right shell is one end open -ended cavity, is equipped with annular protruding edge on the accent of left and right shell respectively, and sealing connection between the two protruding edges forms the cavity between the left and right shell, presss from both sides between the two protruding edges and is equipped with the rubber membrane, and the rubber membrane separates the cavity for water cavity and air cavity, is equipped with the water injection well choke that feeds through with the water cavity on the left shell, is equipped with the air cock that feeds through with the air cavity on the right shell, is equipped with nitrogen gas in the air cavity, is equipped with the check valve in the air cock. The advantage is: through the structure redesign to junction planning, adopt the mode of rubber membrane with the diaphragm, moreover will the diaphragm press from both sides and locate between the two protruding edges, can improve the life of hanging stove, reduce the fault rate of hanging stove, expansion tank's sealing performance reinforcing simultaneously separates and keeps off the effect and improve.
Description
Technical field
The utility model relates to the technical field of wall-hung boiler, especially relates to a kind of wall-hung boiler expansion tank.
Background technology
Expansion tank is the vitals in wall-hung boiler system, and its effect is the breathing amount of water in collecting and bucking-out system, also as system water supply.Expansion tank traditional at present, comprise oval left and right shell, left and right shell is the cavity of one end open, the accent of left and right shell is respectively equipped with the convex edge of annular, be tightly connected between two convex edges, between left and right shell, form chamber, between left and right shell, be provided with barrier film.The barrier effect of this barrier film is poor, and the structure of global design makes sealing property reduce, after Long-Time Service, there will be barrier film breakage, and in the phenomenon that the junction of two convex edges leaks air, cause the fault rate of whole wall-hung boiler to promote, service life reduces.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of service life can improving wall-hung boiler, reduces the fault rate of wall-hung boiler, and the sealing property of expansion tank strengthens simultaneously, the wall-hung boiler expansion tank that barrier effect improves.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of wall-hung boiler expansion tank, comprise oval left and right shell, left and right shell is the cavity of one end open, the accent of left and right shell is respectively equipped with the convex edge of annular, be tightly connected between two convex edges, form chamber between left and right shell, be folded with rubber membrane between two convex edges, chamber is divided into water cavity and air cavity by rubber membrane, left shell is provided with the water nozzle be communicated with water cavity, right shell is provided with the valve be communicated with air cavity, is provided with nitrogen in air cavity, is provided with check valve in valve.
The utility model is set to further: when not intaking in described water cavity, and described rubber membrane expands to water cavity direction and forms protuberance.
The utility model is set to further: the anchor ring that described two convex edges are relative is respectively equipped with groove, and the edge of described rubber membrane is provided with and the bulge loop that can be arranged in groove.
The utility model is set to further: described right shell is provided with leg-of-mutton lug boss, and lug boss is provided with installing rack.
The utility model is set to further: described valve is located on lug boss.
By adopting technique scheme, the technique effect that the utility model reaches is: by redesigning planning to the structure of junction, barrier film is adopted the mode of rubber membrane, and diaphragm clip is located between two convex edges, the service life of wall-hung boiler can be improved, reduce the fault rate of wall-hung boiler, the sealing property of expansion tank strengthens simultaneously, and barrier effect improves.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1,2, a kind of wall-hung boiler expansion tank disclosed in the utility model, comprise oval left and right shell 10,11, left and right shell 10,11 is the cavity of one end open, the accent of left and right shell 10,11 is respectively equipped with the convex edge 12 of annular, be tightly connected between two convex edges 12, chamber is formed between left and right shell 10,11, rubber membrane 13 is folded with between two convex edges 12, the anchor ring that two convex edges 12 are relative is respectively equipped with groove, and the edge of rubber membrane 13 is provided with and the bulge loop 19 that can be arranged in groove.Chamber is divided into water cavity 14 and air cavity 15 by rubber membrane 13, and left shell 10 is provided with the water nozzle 16 be communicated with water cavity 14, and right shell 11 is provided with the valve 17 be communicated with air cavity 15, is provided with nitrogen in air cavity 15, is provided with check valve 18 in valve 17.
When not intaking in water cavity 14, rubber membrane 13 expands to water cavity 14 direction and forms protuberance 20.Right shell 11 is provided with leg-of-mutton lug boss 21, and lug boss 21 is provided with installing rack 22, and wherein valve 17 is located on lug boss 21.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
