The routine building Pipe fitting for water central heating generally adopts the binding or the bellmouth welding type mode of connection of FERRULETYPE, and ferrule-type pipe fitting is when installation and maintenance; Want sawed-off copper pipe end, when copper pipe falls short of, also take copper pipe welding lengthening; Complex process, and must change snap ring accessory, the especially installation of bellmouth pipe fitting and must adopt welding could realize effectively being connected with replacing; Not only energy consumption is big, and owing to the reason of welding procedure can be brought potential safety hazard, causes accidents such as fire easily.
Summary of the invention
The present invention the technical problem that will just solve just provide a kind of reasonable in designly, simple in structure, connect pipe joint quickly and easily between pipe fitting.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme:
Pipe joint; Comprise link body and card pressure body, described link inner body wall is divided into thread section and smooth section, and described card presses body to be provided with pipe hole; Described link body is provided with the pipe fitting interface; Described link inner body wall screw thread is arranged on the inwall of pipe fitting interface, and described card presses external wall to be provided with and the corresponding outside thread of pipe fitting interface inner thread, and described link inner body wall smooth section one end is provided with bulge loop; The other end and thread section are adjacent, and described link inner body wall smooth section is provided with the O RunddichtringO.
Described pipe fitting interface is 2-6.
Described link inner body wall smooth section and thread section adjacent are cone structure, and it is the cone structure that is complementary with link inner body wall smooth section and thread section adjacent that said card is pressed the end outer ring surface of body.
Described card presses end of body to be provided with vertical fluting.
It is polygon structure that described pipe fitting interface outer wall and card are pressed external ring wall.
Described bulge loop sidewall is provided with seal ring.
Pipe fitting interface of the present invention can be arranged to two logical, threeway, four-way, five-way and six logical structures for various setting types such as straight line type, rectangular shape, acute angle type or obtuse angle types; Utilize the bulge loop of the link inner body wall smooth section one end setting pipeline that is located by connecting, make the pipe fitting of various nonstandard Connecting format connect and become very convenient.The present invention is reasonable in design, and link inner body wall smooth section one end is provided with bulge loop, and described bulge loop sidewall is provided with seal ring, and link inner body wall smooth section is provided with the O RunddichtringO, is convenient to good seal performance is installed; Link inner body wall smooth section and thread section adjacent are cone structure, and it is the cone structure that is complementary with link inner body wall smooth section and thread section adjacent that card is pressed the end outer ring surface of body, have strengthened the tightness that cooperates; Card presses end of body to be provided with vertical fluting, is convenient to the chucking between pipe fitting and card pressure body, makes clamping more firm; It is polygon structure that described pipe fitting interface outer wall and card are pressed external ring wall, is convenient to tool positioned and screws; Have characteristic and advantages such as simple and direct, simple in structure, that replacing is easy to maintenance, cost is low are installed, and replacing speed is fast, cheap.
