A kind of anti-rust and dead structure of metal joints of domestic water pipes

Abstract

The invention discloses a rusting-preventing structure for a household water pipe metal joint. The rusting-preventing structure comprises a water inlet pipe, and a liquid inlet hopper is arranged at the top of a liquid storage tank. A connecting shaft is arranged between the liquid inlet hopper and an upper cover, and a pressing air bag is arranged at one end of a containing box. A filtering plateis arranged inside the containing box, and the outer surface of a sleeve is provided with a corrosion-preventing coating. An internal thread is arranged on the inner wall of the sleeve, and the outersurfaces of a first connecting pipe and a second connecting pipe are provided with external threads correspondingly. According to the rusting-preventing structure, the first connecting pipe and the second connecting pipe can be connected in the sleeve, sealing rings are arranged on the positions, close to the sleeve, of one ends of the first connecting pipe and the second connecting pipe correspondingly, thus by manually pressing the pressing air bag, a rust remover can be extruded into the sleeve through the pressure, the rust remover is extruded to the outer surfaces of the first connectingpipe and the second connecting pipe advantageously, the problem that corrosion rusting caused by surrounding media on the first connecting pipe and the second connecting pipe is effectively solved, and the service life of pipelines is prolonged.

Description

technical field [0001] The invention relates to a water pipe structure, in particular to a rust-proof structure for metal joints of household water pipes. Background technique [0002] A large number of water pipes are used in daily life, and improper maintenance of water pipes in general households is prone to rust, water leakage and seepage, and is easy to pollute water quality. Water pipes are affected by corrosion and their service life is reduced. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an anti-rust structure for metal joints of household water pipes, which can enhance the anti-rust performance of the water pipes and prolong the service life of the water pipes. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0005] The present invention is an anti-rust structure ...
