Abstract

The utility model relates to a drain pipe fitting, and belongs to the technical field of drain pipes. The drain pipe fitting comprises a main pipe and side pipes, wherein the side pipes are connected with the main pipe through a three-way joint or four-way joint in a sealing way. The drain pipe fitting is characterized in that: a nozzle of the three-way joint or four-way joint is detachably and tightly bolted with a pipe sleeve, and the pipe sleeve is tightly bolted with the side pipes; and a guide drainage ditch is also arranged on the inner wall of the three-way joint or four-way joint. The drain pipe fitting has the beneficial effects that: through the guide drainage ditch arranged on the three-way joint or four-way joint, water flows into the main pipe along the guide drainage ditch, so that the residential noise is effectively reduced, and the whole device has a silencing effect.

Description

A kind of water-drainage tube part

Technical field

The utility model relates to the waste pipe technical field, especially relates to a kind of novel water-drainage tube part with erasure effect.

Background technique

Resident's daily life for ease, common building all can be provided with waste pipe, but general waste pipe noise is all bigger, plastic drain-pipe particularly, owing to inner wall smooth, fluid resistance is little, and flow velocity is fast, and Strike note is big, so can produce bigger drainage noise.Especially at night, when the draining of upper strata, the noise of bottom can have influence on the resident's of lower floor rest.

The model utility content

In view of above phenomenon, the technical problem that the utility model solved is to provide a kind of novel water-drainage tube part with erasure effect.

The technical problem that the utility model solved adopts following technological scheme to realize:

A kind of water-drainage tube part; Comprise and being responsible for and side pipe; Said side pipe is realized being tightly connected through threeway or four-way and the said person in charge; It is characterized in that: the mouth of pipe at said threeway or four-way also removably closely is bolted with a pipe box, closely is spirally connected between said pipe box and the said side pipe, on the inwall of said threeway or four-way, also is provided with the pilot flow tank.

Said pilot flow tank designs twist, accounts for 1/3 left and right area of threeway or four-way tube wall.

The beneficial effect that the utlity model has is: through the pilot flow tank is set on said threeway or four-way, current flow into along the pilot flow tank and are responsible for, and effectively reduce the dwelling house noise, and whole device reaches erasure effect.

Description of drawings

Fig. 1 is the utility model: a kind of structural representation of threeway water-drainage tube part;

Fig. 2 is the utility model: a kind of structural representation of four-way water-drainage tube part;

Fig. 3 is the utility model: the structural representation of pilot flow tank.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

Embodiment 1: with reference to Fig. 1 and shown in Figure 3; A kind of water-drainage tube part; Comprise be responsible for 1 with side pipe 2, side pipe 2 through threeway 3 be responsible for 1 and realize being tightly connected, removably closely be bolted with pipe box 4 at the mouth of pipe of threeway 3; Closely be spirally connected between pipe box 4 and the side pipe 2, on the inwall of threeway 3, be provided with pilot flow tank 6.

Pilot flow tank 6 designs twist, accounts for 1/3 left and right area of threeway 3 tube walls.

Embodiment 2: with reference to Fig. 2 and shown in Figure 3; A kind of water-drainage tube part; Comprise be responsible for 1 with side pipe 2, side pipe 2 through four-way 5 be responsible for 1 and realize being tightly connected, removably closely be bolted with pipe box 4 at the mouth of pipe of four-way 5; Closely be spirally connected between pipe box 4 and the side pipe 2, on the inwall of four-way 5, be provided with pilot flow tank 6.

Pilot flow tank 6 designs twist, accounts for 1/3 left and right area of four-way 5 tube walls.

More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.

Claims

1. water-drainage tube part; Comprise and being responsible for and side pipe; Said side pipe is realized being tightly connected through threeway or four-way and the said person in charge; It is characterized in that: the mouth of pipe at said threeway or four-way also removably closely is bolted with a pipe box, closely is spirally connected between said pipe box and the said side pipe, on the inwall of said threeway or four-way, also is provided with the pilot flow tank.

2. a kind of water-drainage tube part according to claim 1 is characterized in that: said pilot flow tank twist.
