Method for machining inner container of water heater by using resin

Abstract

The invention discloses a method for machining an inner container of a water heater by using resin. The resin inner container is provided with a water inlet, a water outlet and a sensor port, and a flange connecting port is formed in the end of a shell. The method comprises the following steps that a flange component, a water inlet composite pipe, a water outlet composite pipe and a temperature sensor port pipe are formed through injection molding; the water inlet composite pipe, the water outlet composite pipe and the temperature sensor port pipe are placed in a forming mold of the resin inner container to be positioned and fixed; the resin inner container is formed in a blow molding mode; the flange component is connected with the resin inner container; the water inlet and the water outlet of the resin inner container, the flange connecting port and an outer connecting port of a temperature sensor are sealed tightly, and the preset pressure is adopted for the sealing bulge test; theouter surface of the resin inner container is activated to form a relatively rough anti-skid surface; a reinforcing material for increasing the stress strength of the resin inner container is wound around the outer surface of the resin inner container; the reinforcing material is solidified; and the sealing performance is detected through the bulge test. According to the inner container prepared through the method, the overall strength is high, the structural stability is good, and the use is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of processing water heater inner tanks, in particular to a method for processing water heater inner tanks with resin. Background technique [0002] When the water heater resin liner in the prior art is made, the connection parts such as the water inlet, the water outlet, and the fixing hole of the heating structure are different in structure and connection and fixing method, and each connection part is prone to deformation and fracture, resulting in water seepage and leakage, which is easy cause use and safety hazards. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a water heater resin liner processing technology; the present invention can ensure high overall strength and good structural stability of the water heater resin liner, and seal between connected parts The connection is reliable, the servi...
