Abstract
An inner body of fast hot water heater comprises a stainless steel cylinder 1 and a stainless steel upper and lower end caps 2, the upper end cap is welded with a heat tube 4 before the inner body is assembled, a sealing pad 3 is arranged into the upper and lower end caps 2, and then the cylinder is arranged between the upper and lower end caps 2, the surfaces of the upper and lower flanges of the cylinder contact with the sealing pad. A certain pressure is applied between the upper and lower end caps, so that the sealing pad 3 generates the required deformation and then inwardly presses down the curled edges of the upper and lower end caps to form an inverse clasp, the inverse clasp is pressed on the curled edge of the cylinder 1, thereby realizing the connection. As the flexible sealing pad is arranged between the end caps of the cylinder, the cylinder and the end caps will not generate the inner stresses when heat expansion and cold contract, and the flexible can ensure that the inner body has good sealing performance during long-term use without water leakage.
Description
Technical field
The utility model relates to a kind of inner bag that is used on Instant heating type (formula fast) water heater, and this inner bag is by cylindrical shell, and two end caps and two sealing gaskets are formed, and the simple cost of manufacturing process is low, and the leakproof outlet capacity is very good.
Background technology
Existing immediately heating water heater inner bag can be divided into three major types: the one, and the red copper cylindrical shell is connected by soldering with two red copper end caps and seals, the 2nd, cup-shaped plastics (thermosetting) cylindrical shell and a red copper end cap are riveted, and seal by sealing gasket in riveted joint place, the 3rd, stainless steel cylinder and two stainless steel end caps weld (argon arc welding or soldering).First kind and second kind of inner bag, its leakproof outlet capacity is fine, but the higher (red copper of material cost, thermosetting plastics), the third cost is lower, but because stainless heat transfer property is bad, therefore at water heater working with in the handoff procedure of not working, the variation of temperature degree of irregularity is bigger on the inner bag, and weld produces very big internal stress, and this internal stress makes the weld cracking and causes and leak.Domestic existing a lot of products are because this kind is former thereby cause a large amount of reprocessing and returning goods.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of low cost, and manufacturing process is comparatively simple, and the inner bag of the fast water heater that leaks of not ftractureing.
The technical solution of the utility model is: the inner bag that designs a kind of fast water heater, comprise stainless steel cylinder and two stainless steel end caps, described cylindrical shell two ends have flange to form flange face, described end cap is a bowl cover shape, between the flange face of cylindrical shell and end cap rubber gasket is arranged, the flange face of described bowl cover and cylindrical shell is riveted into one.
The utility model is owing to adopted the riveted joint mode, the flexible gasket that can compress is arranged between the cylindrical shell end cap, can not produce internal stress in cylindrical shell and the end cap when therefore expanding with heat and contract with cold, and flexible sealing gasket can be guaranteed not produce drainage by inner bag favorable sealing property in long-term the use.
Description of drawings
Fig. 1 is a generalized section of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1, it is a kind of inner bag of fast water heater, comprises stainless steel cylinder 1, and stainless steel is end cap 2 up and down.Upper end cover has carried out the soldering welding with electrothermal tube 4 before the inner bag assembling, sealing gasket 3 is put into end cap 2 up and down, again cylindrical shell is put into up and down between the end cap 2, the flange face up and down of cylindrical shell contacts with sealing gasket. applying certain pressure between the end cap up and down, make sealing gasket 3 produce needed deflection, afterwards the flange that upper and lower side covers is overwhelmed toward in, form back-off, this back-off is pressed on the flange flange face of cylindrical shell 1, thereby has realized that connection connects.
The foregoing description is of the present utility model a kind of, and every and the utility model structure are identical substantially or utilize the novel invention spirit of this reality, and the small improvement of being done on the utility model all belongs to the scope that the utility model is protected.
Claims (1)
1. the inner bag of a fast water heater, comprise stainless steel cylinder and two stainless steel end caps, it is characterized in that: described cylindrical shell two ends have flange to form flange face, described end cap is a bowl cover shape, between the flange face of cylindrical shell and end cap rubber gasket is arranged, the flange face of described bowl cover and cylindrical shell is riveted into one.
