Abstract

The utility model relates to a joint for an upper and a lower water pipes in construction engineering, comprising pipe bodies respectively composed of a main loop and a branch loop. The utility model is characterized in that the center line of the pipe body of the branch loop and a circular arc of the inner wall of the pipe body of the main loop are in tangent connection. When flowing water in the branch loop flows into the main loop along the tangential direction of a circular arc of the inner wall of the main loop, the flowing water rotates to flow downwards along the pipe wall of the main loop; accordingly, the water flow noise can be decreased to be small.

Description

Construction work is with upper and lower water hush pipe joint

The utility model is a kind of construction work pipe fitting, the upper and lower water hush pipe joint that particularly a kind of construction work is used.

Upper and lower waterpipe in the construction work now and pipeline fittings thereof often adopt engineering plastics to make, the shortcoming of this pipeline and pipeline fittings thereof is that soundproof effect is poor, so current by the time produce bigger noise, for addressing this problem, the applicant has declared the patent application of relevant " Silencing tube material ", but for pipeline fittings, for example the noise reduction problem of union is not resolved always.

The purpose of this utility model provides a kind of novel union, and it can overcome existing shortcoming in the prior art, and noise is reduced.

The purpose of this utility model is achieved in that it comprises the body of being made up of major loop and Zhi Huilu, it is characterized in that the inwall circular arc of the center line of Zhi Huilu body and major loop body is tangent.

When the flowing water among the Zhi Huilu when the circular arc tangential line direction of major loop inwall flow in the major loop, promptly dirty along the tube wall rotation of major loop, like this can be so that the current noise is reduced to very little.

Have certain tapering if the bore of major loop is made into, promptly Shang Duan diameter then can make the noise of flowing water further reduce greater than the diameter of lower end.

Technique scheme can be used for traditional union, also can be used for the union that port has the fast sealing device.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is the outer shape schematic diagram that the utility model is used to have the union of fast sealing structure.

Fig. 2 is the upward view of Fig. 1.

1 is the major loop body among the figure, the 2nd, the Zhi Huilu body, as depicted in figs. 1 and 2, each port at pipeline is equipped with the fast sealing device, 3 is wherein union cap (UC)s among the figure, and as seen from Figure 2, the inwall circular arc of the center line of the body of Zhi Huilu and major loop body is tangent, the upper end diameter of while major loop body is greater than lower end diameter, and is tapered.

Claims

1, construction work use, sewer pipe joint, it comprises the body of being made up of major loop and Zhi Huilu, it is characterized in that the inwall circular arc of the center line of Zhi Huilu body and major loop body is tangent.

2, according to the said union of claim 1, the upper end diameter that it is characterized in that the major loop body is greater than lower end diameter.
