Background

The PVC drain pipe is produced by using sanitary polyvinyl chloride resin as main material, adding proper amount of stabilizer, lubricant, stuffing, coloring agent, etc. and through extrusion in plastic machine, injection in injection molding machine, cooling, curing and other steps.

Among the prior art, in the PVC drainage pipe use of existence, can't guarantee that the water pipe does not receive the infringement of external high temperature environment for drain fitting can the erosion of manual high temperature, makes the drain pipe condition such as ageing appear, can cause the drain pipe to appear under the condition of leaking, makes the life of drain pipe reduce simultaneously, can increase the installation cost of drain pipe.

Disclosure of Invention

In order to overcome the above-mentioned drawbacks of the prior art, embodiments of the present invention provide a high temperature resistant PVC drain pipe, which can prolong the service life of the drain pipe by preventing the inner sleeve from being damaged by the external high temperature environment through the arrangement of the protective cotton and the fixed shell, so as to solve the above-mentioned problems in the background art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a high temperature resistance PVC drain pipe fitting, includes interior sleeve pipe, interior sheathed tube outside fixed mounting has the protection cotton, the cotton outside fixed mounting of protection has fixed shell, interior sheathed tube outside fixed mounting has the movable rod, the top fixed mounting of movable rod has the fixed plate, the movable rod is made for concertina type structure.

In a preferred embodiment, a limiting spring is fixedly mounted on the outer side of the inner sleeve, the top end of the limiting spring is fixedly connected with the inner side of the fixed shell, and the limiting spring is sleeved on the outer side of the movable rod.

In a preferred embodiment, a fixing reed is fixedly installed at the top end of the fixing plate, and a protection pad is fixedly installed at the top end of the fixing reed.

In a preferred embodiment, the protective cotton is made of a high-temperature resistant material, and the fixed shell is made of an elastic material.

In a preferred embodiment, the limiting spring is made of a metal material, and the protection pad is made of elastic plastic.

The invention has the technical effects and advantages that:

1. through the arrangement of the protective cotton and the fixed shell, when the PVC drainage pipe fitting is used, the inner sleeve can not be damaged by external high-temperature conditions through the double-layer protection of the fixed shell and the protective cotton, so that the drainage pipe fitting can keep a good working state, the service life of the drainage pipe can be ensured, and compared with the prior art, the PVC drainage pipe fitting has the improvement of high-temperature resistance;

2. through the setting of movable rod and limited spring, when carrying out PVC water piping spare's installation, through the movable rod shrink performance, make fixed shell can contract for PVC water piping spare can adapt to the passageway in different apertures, make installing and dismantling that PVC water piping spare can be better, compare with prior art, have the progress that makes things convenient for water piping spare installation.
