Abstract

The utility model relates to a self-welding-type water pipe joint. The inner wall of the interface of the joint made of the red copper is provided with an annular groove; solder is cast in the groove. When a waterway pipe is installed, the pipe is inserted into the interface of the joint; the pipe and the joint are naturally welded together through specific heating. The utility model has the characteristics of convenient pipe installation, long service life, clean pipe, no resistance, no pollution, light weight, etc.

Description

The water pipe head of self-brazing type

The utility model relates to water channel pipeline accessory, mainly is to cooperate with the red copper water inlet pipe, is specially adapted to luxurious hotel, restaurant and housing construction.

The inlet pipe, drain pipe road is one of ingredient of buildings such as hotel, restaurant and private residence, and water pipe head (as threeway, four-way, elbow etc.) is the important accessory of water channel pipeline.What existing water inlet pipe and accessory adopted is galvanized pipe, therefore contains hazardous substancess such as zinc, lead, and water pollution influences health, and need attack the system screw thread, and joint is installed trouble, and the resistance of ducting is big, corrosion easily, and application life is short, defectives such as Heavy Weight.

At present, some high-grade building decoration is used copper plumbing.But the pipe joint of copper plumbing is through being welded to connect, and existing what adopt is the silver soldering technology, and so not only technical difficulty is big, troublesome poeration, and inefficiency, and expense height have influenced and have applied.

The purpose of this utility model is the defective that overcomes prior art, and precasting scolder in a kind of water pipe head is provided, and heats after pipe and joints cooperates, and realizes the water pipe head of the copper product of welding automatically.

The technical scheme of the utility model self-brazing type water pipe head is: the interface inwall of the joint of making at the red copper material is shaped on annular groove, the scolder of casting in the groove.

Self-brazing type of the present utility model water pipe head, its described scolder are soldering tin material or other material.

Self-brazing type of the present utility model water pipe head, its described water pipe head are tee junction or four-way connection or elbow or various terminals such as casing joint or pipe cap.

The utility model discloses a kind of water pipe head, compared with the prior art, have following characteristics: owing to be shaped on groove at red copper connector interface inwall, scolder is cast in the groove, make the water pipe head of self-brazing type, when the water channel pipeline is installed, pipe is inserted in the connector interface, by specific heating, pipe and joints welds together.Compared with the prior art, have easy for installation, long service life, duct cleaning, non-resistance, and characteristics such as copper tube is nontoxic, pollution-free, and is in light weight.

Below in conjunction with Fig. 1 one Fig. 5 embodiment of the present utility model is done detailed explanation.

The utility model relates to the red copper water pipe head, belongs to waterway fitting, comprises various threeway 1, four-way 2, elbow 3 and products such as pipe box 4, pipe cap 5 with footpath, reducing, and specification, model are extremely many.One of its key technology is one groove of interface 6 inwall systems 7 at joint 1,2,3,4,5, two of key technology is the scolders 8 at groove 7 places casting annular one circle, so-called scolder mainly is a soldering tin material, as employing Sn-1 scolder, but also can adopt other various scolders.The water pipe head of making is standby, when installing pipe is inserted in the interface 6 of joint, makes tube outer wall contact cooperation with scolder, adopts specific technology, heats to 250-380 ℃, is generally about 300 ℃, and both weld naturally.

Claims

1, a kind of self-brazing type water pipe head is characterized in that interface (6) inwall of the joint made by the red copper material is shaped on annular groove (7), the scolder (8) of casting in the groove.

2, self-brazing type as claimed in claim 1 water pipe head is characterized in that described scolder is a soldering tin material.

3, self-brazing type as claimed in claim 1 or 2 water pipe head is characterized in that described water pipe head is tee junction or four-way connection or elbow or casing joint or pipe cap.
