Cause to expand pot bottom wrinkling deformation, so as to which the quality and service life of expansion drum can be influenceed.
Utility model content
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of improve and lost the utility model
The expansion tank capable of exchanging inner container surely put, the bottom of its metal cylinder is arranged to raised type cambered surface, instead of conventional metals cylinder
The setting of body bottom indent, so as to solve the problems, such as to cause metal cylinder deformation of bottom when air pressure inside is excessive.
To achieve the above object, the utility model is using following technical scheme：
A kind of expansion tank capable of exchanging inner container for improving spinodal decomposition point, includes metal cylinder, automatic inflating valve and inner bag；
The automatic inflating valve is arranged on the bottom of metal cylinder and connects the cavity of metal cylinder；The inner bag is detachably arranged in metal
At the upper opening of cylinder, wherein, the bottom of the metal cylinder is the raised type cambered surface that can prevent deformation, the automatic inflating valve
Positioned at the center of raised type cambered surface.
As a kind of preferred scheme, it is connected between the inner bag and metal cylinder by flange apparatus.
As a kind of preferred scheme, for outside reflexed formed with the first shirt rim, this is interior at the upper opening of the metal cylinder
Outside reflexed is formed with the second shirt rim at the upper opening of courage, and second shirt rim is folded to be located on the first shirt rim, the flange apparatus bag
Upper flange part and lower flange part are included, first shirt rim and the second shirt rim are located between upper flange part and lower flange part.
As a kind of preferred scheme, the inner bag is quality of rubber materials.
As a kind of preferred scheme, protection cap is arranged with outside the automatic inflating valve, the protection cap is in inverted cone shape and covers
The bottom of metal cylinder.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme is understood：
For this product by the way that the bottom of metal cylinder is arranged into raised type cambered surface, the setting of raised type cambered surface instead of tradition
The setting of bottom centre's indent, the setting of raised type cambered surface prevents expansion drum because of the situation that pressure is excessive and deforms, so as to have
The service life and quality that ensure that expansion drum of effect.
More clearly to illustrate architectural feature and effect of the present utility model, come below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail.

Embodiment
It refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the utility model, include
Metal cylinder 10, automatic inflating valve 20 and inner bag 30.
The automatic inflating valve 20 is arranged on the bottom 11 of metal cylinder 10 and connects the cavity of metal cylinder 10, the bottom 11
For raised type cambered surface, automatic inflating valve 20 is located at the center of raised type cambered surface, and the setting of raised type cambered surface instead of tradition
The center indent of bottom 11 setting, cause bottom 11 to become so as to be effectively prevented when air pressure is excessive in metal cylinder 10
The problem of shape, it is ensured that the quality and service life of product；Protection cap 40 is arranged with outside automatic inflating valve 20, the protection cap 40 is in
Inverted cone shape and the bottom 11 for covering metal cylinder 10, protection cap 40 its effectively protect automatic inflating valve 20, make to fill automatically
Air valve 20 is more longlasting durable.
The inner bag 30 is detachably arranged at the upper opening of metal cylinder 10, between inner bag 30 and metal cylinder 10 by
Flange apparatus 50 is connected, and specifically, outside reflexed is formed with the first shirt rim at the upper opening of the metal cylinder 10
101, for outside reflexed formed with the second shirt rim 301, second shirt rim 301 is folded to be located at the first shirt rim at the upper opening of the inner bag 30
