Abstract
A three-way pipe fitting with a built-in metal close nipple relates to a pipeline connector, mainly comprises an inverted T-shaped three-way pipe fitting, and is characterized in that a metal close nipple is arranged in the connector at the vertical end of the inverted T-shaped three-way pipe fitting; the outer wall of the metal close nipple and the inner wall of the inverted T-shaped three-way pipe fitting are in contact with each other; rotary threads used for connecting with the adjacent pipe fitting are formed on the inner wall of the inverted T-shaped three-way pipe fitting; and the inverted T-shaped three-way pipe fitting is made of PC, PE, or PVC nonmetallic material. The three-way pipe fitting has the benefit that the pipe fitting made of nonmetallic material and the metal connector are combined together, thereby not only avoiding the corrosion to the pipe wall during fluid transmission, but also better realizing the sealing connection with other pipeline members through the metal connector, so as to prolong the service life of the pipe fitting.
Description
Technical field
The utility model relates to pipe joint, specifically is a kind of tee pipe fitting of built-in metal threaded coupling.
Background technique
At present, metallic conduit is widely used in the daily life field as the delivery means of liquid, but in use, can contain corrosive material in the liquid but metal pipe internal wall generation corrosion and aging phenomenon generation owing to transmitting, particularly at the three-way interface place of pipeline, because of pressure and wearing and tearing that its direction that has changed the transmission liquid is subjected to more violent, so three-way interface place more cracky, leakage, so how head it off has become the task of top priority.
The model utility content
The technical problem that the utility model solved is to provide a kind of and is difficult for being corroded in the liquid transmission course, peel off and come off, and the tee pipe fitting of adjacent pipe fitting built-in metal threaded coupling of good seal performance when connecting.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of tee pipe fitting of built-in metal threaded coupling, be mainly ⊥ shape tee pipe fitting, it is characterized in that: be provided with metal threaded interface in the vertical end interface of described ⊥ shape tee pipe fitting, the inwall of the outer wall of described metal threaded interface and ⊥ shape tee pipe fitting contacts, and is shaped on the rotation screw thread on the inwall and is used for joining with adjacent pipe fitting.
Described ⊥ shape tee pipe fitting is made by PC, PE or PVC nonmetallic material.
The beneficial effects of the utility model are that the pipe fitting and the metal interface of nonmetallic material combines, and can prevent from the liquid transmission well and between other pipe element to be tightly connected by metal interface again to the corrosion of tube wall, have increased the working life of pipe fitting.
Description of drawings
