Riveting water storage tank and manufacturing method thereof

Abstract

The invention discloses a riveting water storage tank. The riveting water storage tank comprises an upper tank body and a lower tank body which are mutually buckled and connected, wherein a connecting end of the upper tank body is bent outwards to form an annular folding plate, the connecting end of the lower tank body is bent outwards to form a buckling plate, the buckling plate is an U-shaped folding plate, the buckling plate wraps the annular folding plate, and rivet and fix the annular folding plate; the riveting water storage tank further comprises a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is inserted from the top of the tank body and fixed by welding and is used for adding water into the water storage tank, and at least two through holes are formed in the side wall of the lower part of the water inlet pipe; and the water outlet pipe is inserted from the bottom of the lower tank body and fixed by welding and is used for discharging water in the water storage tank. According to the riveting water storage tank, the welding area can be effectively reduced, the weld joint can be reduced, so that the water leakage phenomenon caused by poor welding can be reduced, the welding can be reduced, the use of nickel paste solder can be reduced, so that the cost can be reduced; and the problem that the water storage tank is deformed and even damaged due to the fact that the pressure in the water storage tank is large is also avoided, so that the pressure resistance of the water storage tank is effectively improved, the service life of a product is guaranteed, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of water storage tanks, in particular to a riveted water storage tank and a manufacturing method thereof. Background technique [0002] In the gas water heater industry, in order to achieve better constant temperature performance, a water storage tank is usually added inside the water heater to alleviate the water temperature fluctuation of the gas water heater when the external water pressure fluctuates; the traditional water storage tank generally adopts the structure of disassembling and assembling components In the form, the parts are threaded and welded. [0003] Existing water storage tanks have the following problems: [0004] (1) During the brazing process, due to the large number of welds and the large welding area, poor welding is prone to occur; [0005] (2) It is spliced ​​and welded, and the weld is easily corroded and leaks; [0006] (3) The pressure resistance is poor, and deformation and b...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the welding of the existing water storage tank is difficult, the defect rate is high, and the pressure resistance is low.
