Description

Core-shifting secondary drainage joint

Technical Field

The utility model relates to an eccentric secondary drainage joint, belonging to the field of building drainage.

Background

The same-layer drainage is characterized in that accumulated water in the falling plate layer is drained through accessories while conventional drainage is conducted, most of the conventional methods at present adopt methods of drilling and connecting saddle-shaped pipe fittings, the cambered surfaces of the saddle-shaped pipe fittings are adhered to pipes, and the axial direction of the interface is perpendicular to the cambered surfaces, so that the scheme has two defects: 1. the water flow part attached to the wall in the vertical pipe can backflush to the descending board layer through the small hole to cause long-term water accumulation; 2. when three-way four-way pipe fittings and other pipe fittings are arranged, the transverse socket occupies most space, saddle-shaped pipe fittings with vertical structures are difficult to arrange in the correct direction, and the applicability is poor, so that a new structure is urgently needed to solve the problem.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a core-shifting secondary drainage joint to solve the problems in the background technology.

In order to realize above-mentioned purpose, a core secondary drainage connects partially, including first even pipe, one side and the second even pipe intercommunication of first even pipe are fixed, be provided with the connecting pipe on the first even pipe, be provided with saddle shape pipe fitting on the first even pipe, saddle shape pipe fitting includes the arc, core tube partially and extends to the inside protruding pipe of first connecting pipe, arc and first even pipe fixed connection, set up core tube partially on the arc, the axis of core tube partially is the acute angle with the installation tangent plane of arc, a side end face that the arc deviates from core tube partially is provided with protruding pipe, and protruding pipe and core tube partially are linked together, protruding pipe passes the aperture of seting up on first pipe and extends to the inside of first even pipe.

Furthermore, the arc-shaped plate, the core shift pipe and the protruding pipe are of an integrated structure.

The utility model has the beneficial effects that: through the inside bellying that is provided with of aperture seted up on first connecting pipe, because the one end of bellying runs through the aperture and extends to the inside of first connecting pipe, and the other end of bellying is linked together with eccentric pipe, prevents that adherence rivers from backflushing back the aperture, the practicality is good.

The axis of core pipe and the installation tangent plane of arc are the acute angle partially, have avoided influencing the installation of pipeline because of the existence of shape of a saddle pipe fitting, simultaneously, conveniently install shape of a saddle pipe fitting on different pipe fittings, like three-way pipe, four-way pipe and swirler etc. application scope is wide.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1-4, the present invention provides a technical solution: a core-shifting secondary drainage joint comprises a first connecting pipe 1, one side of the first connecting pipe 1 is communicated and fixed with a second connecting pipe 2, a connecting pipe 5 is arranged on the first connecting pipe 1, a saddle-shaped pipe fitting is arranged on the first connecting pipe 1, the saddle-shaped pipe fitting comprises an arc plate 7, a core-shifting pipe 8 and a convex pipe 9, the arc plate 7 is fixedly connected with the first connecting pipe 1, the core-shifting pipe 8 is arranged on the arc plate 7, the central axis of the core-shifting pipe 8 and the installation tangent plane of the arc plate 7 form an acute angle, the influence on the installation of a pipeline caused by the existence of the eccentric pipe 8 is avoided, the convex pipe 9 is arranged on the end surface of one side of the arc plate 7, which is far away from the core-shifting pipe 8, the convex pipe 9 is communicated with the core-shifting pipe 8, the convex pipe 9 passes through a small hole 10 formed in the first connecting pipe 1 and extends into the first connecting pipe 1, one end of the convex pipe 9 extends into the first connecting pipe 1 to prevent the back-sticking water flow, the leakage-proof effect is good, and the practicability is good.

The arc plate 7, the eccentric pipe 8 and the protruding pipe 9 are of an integrated structure, so that the saddle-shaped pipe fitting can be manufactured conveniently, and meanwhile, the saddle-shaped pipe fitting and the first connecting pipe 1 are enabled to have good sealing performance.

Through the one end with core pipe 8 partially and reverse extension to first even 1 inside protruding pipe 9 of managing be linked together, under the effect of protruding pipe 9, prevent that adherence rivers from backflushing back aperture 10, cause the water leakage, the leak protection performance is better, simultaneously, because the axis of core pipe 8 partially is the acute angle with the installation tangent plane of arc 7, make even core pipe 8 and first even 1 formation core installation of managing, avoided because of the existence of saddle pipe fitting, influence the installation of pipeline, and simultaneously, conveniently make saddle pipe fitting and three-way pipe, four-way pipe and swirler be connected, the application range of saddle pipe fitting has been increased, therefore, the high applicability.
