Abstract
The utility model belongs to the field of water supply and drainage pipe fittings and discloses a three-way pipe which comprises a pipe fitting, an outlet arranged on the outer wall of the pipe fitting, and a branched pipe positioned on the outlet. A threaded port used for being connected with a valve is arranged on the branched pipe, and the branched pipe and the pipe fitting are formed by welding or at one step. The three-way pipe is simple in structure and convenient in water intake, can fully guarantee pressure in a pipeline in the process of water supply, and has a function of exhausting during first-time water supply.
Description
Technical field
The utility model discloses a kind of three-way pipe, belong to plumbing pipe fitting field.
Background technique
Current feedwater by the structure that pipe fitting adopts is: embedded metal inserts forms internal sealing plug, and overcoat metal insert forms external sealing plug.The problem that such structure exists is: one, metal insert is prone to corrosion in water body environment content, and silk mouth is ineffective; Two, the metal insert of corrosion causes water pollution, and feedwater requires high by the sanitary standard of pipe fitting, and the water that corrosion metals inserts causes pollutes to follow-up water and causes very large threat; Three, the technique of embedded, overcoat metal insert and structure cause the increase of fabricating cost; Four, metal insert and plastic pipe directly cause seepage in conjunction with the normal situation that occurs that pine is split.
Occurred that subsequently the patent No. is 201020564045.9, denomination of invention is the patented technology scheme of feedwater plastic pipe.This patented technology scheme is as follows: feedwater plastic pipe, by pipe fitting, conversion adapter, silk mouthful, formed, pipe fitting is direct body or elbow body or threeway body or four-way body or stop valve base, and conversion adapter is arranged on pipe fitting port, and silk mouth is arranged on inwall or the outer wall of switching.The material of pipe fitting is three type polypropylene (PP-R).This patented technology scheme has adopted plastic material, although solved the problem of polluting.But its technological scheme adopting is still the form of three-way joint element, has brought inconvenience to installation, can not solve well in actual applications the problem of exhaust and water intaking.
Summary of the invention
For solving the problems of the technologies described above, it is a kind of simple in structure that the utility model provides, and water intaking is convenient, and, in water flowing process, can fully guarantee ducted pressure, and when first water flowing, there is the pipe fitting of exhaust, pressure-reducing function.
For realizing above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of three-way pipe, comprises pipe fitting and is arranged on the outlet on pipe fitting outer wall, it is characterized in that, also comprises the arm being positioned in described outlet, is also provided with the silk mouthful for connecting valve on described arm, passes through welding or once-through between described arm and pipe fitting.
The internal diameter of arm described in the utility model is less than the internal diameter of pipe fitting.
In outlet described in the utility model, be also provided with boss, described arm stretches into pipe fitting through boss.
Working principle of the present utility model and working procedure are:
After installing, on arm, connect valve, state conventionally, valve closing, during first water flowing, by valve opening, to reach the effect of exhaust; Treat exhaust, reduce pressure complete, by valve closing, in the time of need to fetching water, Open valve.In the time of need to testing certain any pressure, at the valve pressure gauge of going into the street, Open valve, can complete test.
Due to, the utility model has adopted said structure, has following beneficial effect:
First, on pipe fitting, be provided with arm, and, on arm, there is silk mouthful, facilitated the installation of valve or the installation of testing instrument.
Secondly, between arm and pipe fitting, by welding or once-through, guaranteed the sealed type of pipe fitting;
The 3rd, the internal diameter of arm is less than the internal diameter of pipe fitting, has guaranteed that the pressure in pipe fitting can not be affected because being provided with arm;
The 4th, be provided with boss, be the stability that has fully guaranteed arm in mounted valve, testing instrument or work progress, thereby guaranteed the stability between arm and pipe fitting.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is schematic perspective view of the present utility model.
In figure, 1, pipe fitting, 2, arm, 3, silk mouthful, 4, boss.
