Abstract

The utility model relates to a universal loose connecting pipe fitting which is composed of a lock pipe, a sealing ring, a lock nut, an expansion ring, and a double-head and double-spherical surface connecting head. An inner port of the lock pipe is installed in the sealing ring, the spherical surface of the double-head and double-spherical surface connecting head is made to just face the inner port of the lock pipe, and then the lock nut is utilized to tightly lock the double-head and double-spherical surface connecting head and the lock pipe. The utility model ensures that because of the causes of installation or manufacture, etc., when two butted pipelines generating axial line displacement, installation and butt joint can be carried out rapidly, and phenomena of leakage, etc. can be guaranteed not to occur.

Description

Universal loose joint pipe fitting
The utility model relates to the hot-water heating pipe fitting, specifically a kind of universal loose joint pipe fitting.
At present China's hot-water heating pipe fitting all belongs to hard connection, can only in all sorts of ways pipe removed to bend to connect.This mounting type, not only time-consuming but also take a lot of work, also cause pipe-line system the seepage phenomenon to occur easily.
The purpose of this utility model provides a kind of Fast-mounting tube fitting reliable, easy, that can adjust axial deviation.
The purpose of this utility model is achieved in that
A kind of universal loose joint pipe fitting is characterized in that: it is made up of lock pipe, seal ring, locknut, piston ring, the two spherical joints of double end; The two spherical joints of double end are the hollow tubular that respectively there is a spherical surface body at two ends, respectively are inserted in a locknut in this two spherical surface body symmetrically, and piston ring is housed in this locknut bottom and spherical surface body constitutes sealing.Locknut is with the lock pipe that is threaded, and the top that seal ring and spherical surface body are housed in this lock pipe constitutes hydrodynamic reciprocating sealing.This lock pipe end in addition has connecting thread.The material of described lock pipe, locknut, the two spherical joints of double end is malleable iron or copper.
The utility model has the advantages that:
1, utilizes hard connecting mode, solved adapter two ends axial displacement (dislocation) problem.
2, Placement firmly, reliably is not prone to the seepage phenomenon.
3, saving of labor during installation, maintenance, save time, increase work efficiency.
Concrete structure of the present utility model is provided by the following drawings:
Accompanying drawing is the section of structure under the universal loose joint pipe fitting of the utility model assembled state.
Universal loose joint pipe fitting is made up of lock pipe 1, seal ring 2, locknut 3, piston ring 4, the two spherical joints 5 of double end.
Locknut 3 is inserted in the two spherical joints 5 of double end, the piston ring 4 of packing in locknut.To lock the interior 1 mouthful of seal ring 2 of packing into of pipe.The sphere of the two spherical joints 5 of double end is aimed at lock pipe 1 internal orifice, uses locknut 3 that two spherical joints 5 of double end and lock pipe 1 are locked then.
The lock pipe 1 at two can guarantee that all the time the sphere of the two spherical joints 5 of double end and lock pipe 1 are under the effect of seal ring 2, make pipeline keep sealing state when the bigger situation of axial displacement (dislocation) like this.

Claims (2)

1, a kind of universal loose joint pipe fitting is characterized in that: it is made up of lock pipe (1), seal ring (2), locknut (3), piston ring (4), the two spherical joints (5) of double end; The two-sided joint of double end (5) respectively has the hollow tubular of a spherical surface body for two ends, respectively be inserted in a locknut (3) in this two spherical surface body symmetrically, this locknut bottom is equipped with piston ring (4) and is constituted sealing with spherical surface body, locknut (3) is with the lock pipe (1) that is threaded, the top that seal ring (2) and spherical surface body are housed in this lock pipe constitutes hydrodynamic reciprocating sealing, and this lock pipe end in addition has connecting thread.
2, universal loose joint pipe fitting as claimed in claim 1 is characterized in that: the material of lock pipe (1), locknut (3), the two spherical joints (5) of double end is malleable iron or copper.
