Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to provide a pressure tank with stable structure.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a pressure tank, comprising a tank body and a circle of brackets distributed outside the tank body, the brackets are in an inverted L shape, and are characterized in that a connecting plate is vertically provided between the upper end of each bracket and the tank body, and the cross-section of the connecting plate is an arc shape matching the tank body; one side of the connecting plate is attached to the outer surface of the tank body, and the connecting plate and the tank body are welded and fixed, and the other side of the connecting plate is fixed on the bracket; an annular limit seat is integrally formed on the outer wall of the tank body, the limit seat and the tank body are coaxially arranged, and each connecting plate is pressed against the bottom surface of the limit seat.

[0007] The connecting plate and the limit seat are used together to support the tank body upward so that the weight of the tank body is directly applied to the bracket, thereby effectively reducing the stress at the welding position between the connecting plate and the tank body, ensuring that the bracket always provides effective support to the tank body, thereby greatly enhancing the overall structural stability of the pressure tank.

[0008] In the above-mentioned pressure tank, the above-mentioned connecting plate and bracket are an integrated structure to provide more stable and reliable support for the tank body.

[0009] In the above-mentioned pressure tank, the tank body is composed of a coaxially arranged upper barrel and lower barrel. The lower outer wall of the upper barrel is bent outward to form an annular upper flange, and the upper outer wall of the lower barrel is bent outward to form an annular lower flange.

The above-mentioned design facilitates the processing and design of the tank body.

[0010] In the above-mentioned pressure tank, the upper flange and the lower flange are fixedly connected by welding, which has the advantages of simple structure and convenient connection.

[0011] In the pressure tank, an annular welding groove for filling with welding liquid is formed between the outer wall of the upper flange and the outer wall of the lower flange, and the welding groove is coaxially arranged with the upper flange. The provision of the welding groove can make welding more convenient.

[0012] In the above-mentioned pressure tank, the axial cross-section of the welding groove is V-shaped, which is conducive to the uniform filling of the welding liquid in the welding groove and further enhances the connection stability of the upper flange and the lower flange.

[0013] In the above-mentioned pressure tank, one side of the thickness of the bracket is inwardly recessed to form a groove whose shape and size match the bracket, so as to reduce the weight of the bracket.

[0014] In the above-mentioned pressure tank, a mounting plate is horizontally fixed to the bottom of the bracket, and bolt holes are vertically passed through the mounting plate to facilitate the installation and positioning of the bracket.

[0015] Compared with the existing technology, this pressure tank supports the tank body upward through the connection plate and the limit seat, so that the weight of the tank body is directly applied to the bracket, thereby effectively reducing the stress at the welding position between the connection plate and the tank body, ensuring that the bracket always provides effective support to the tank body, thereby greatly enhancing the overall structural stability of the pressure tank.
