Abstract
The utility model discloses a hot water pipe joint. The hot water pipe joint comprises a joint and a lock sleeve with internal threads, wherein an axial penetrating water hole is formed in the center of the joint, the joint comprises a connection part, a fixed part and a water pipe nesting part, the three of which are orderly connected with one another, a groove is formed in the water pipe nesting part, an expansion sleeve is embedded in the groove, the expansion sleeve fills the groove and is combined with the water pipe nesting part to form a smooth outer wall, and the lock sleeve is screwed down with the external threads of the fixed part by virtue of the internal threads to form threaded fixation with the joint. The hot water pipe joint is characterized in that the joint is divided into the connection part, the fixed part and the water pipe nesting part, the expansion sleeve is arranged on the water pipe nesting part, and the expansion sleeve is preheated to expand so as to compensate the inner diameter of a water pipe, and therefore, the water pipe is certainly fixed between the lock sleeve and the joint without dropping. Compared with the prior art, the hot water pipe joint is firmer in connection and longer in service life.
Description
[technical field]
The utility model relates to connection device technical field, particularly a kind of pipe joint of hot water.
[background technique]
In water circuit system, unavoidably use water pipe adapter.The comparatively easy water tubular union of existing use mainly comprises threaded connecting sleeve and screw fastening collar, when use, one end of two water pipes is linked into respectively to the two ends of threaded connecting sleeve, then screw fastening collar is screwed in to be threaded and put, by fixing to threaded connecting sleeve and water pipe sealing, the Placement of this water pipe adapter not only sealing is poor, and working life is shorter, when when connecting warm water or hot water pipeline, due to the self-characteristic of water pipe heat expansion shrinkage, the as easy as rolling off a log water pipe socket place enlarged-diameter that makes, come off thereby cause, this joint connects insecure, be difficult to satisfy the demands.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of pipe joint of hot water, can improve connectivity robustness, and anti-water stopping tube comes off, and increases the service life.
For achieving the above object, the utility model proposes a kind of pipe joint of hot water, comprise joint and tapped lock sleeve, the center of joint offers the water hole of axial perforation, described joint comprises the joint connecting successively, fixing part and water pipe belled part, on the outer wall of described fixing part, be provided with the outside thread corresponding with the internal thread of lock sleeve, described water pipe belled part is taper, on water pipe belled part, offer groove, in groove, be inlaid with expansion sleeve, described expansion sleeve is filled up groove and is formed smooth outer wall with water pipe belled part, described lock sleeve is spirally connected fixing with joint formation by internal screw-thread screw on the outside thread of described fixing part.
As preferably, the thickness of described lock sleeve one end is risen gradually and is increased by internal thread.
As preferably, the joint of described fixing part and water pipe belled part is provided with seal ring.
As preferably, described joint is provided with internal thread or outside thread.
The beneficial effects of the utility model: the utility model is by being divided into joint joint, fixing part and water pipe belled part, by expansion sleeve being set on water pipe belled part, after the pre-thermal expansion of expansion sleeve, to compensate water pipe internal diameter, thereby ensure that water pipe is fixed between lock sleeve and joint, prevents from coming off, compared with prior art, the utility model connects more firm, has longer working life.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model.
In figure: 1-joint, 2-internal thread, 3-lock sleeve, 4-joint, 5-fixing part, 6-water pipe belled part, 7-outside thread, 8-groove, 9-expansion sleeve, 10-seal ring, 11-water hole.
[embodiment]
Consult Fig. 1, the utility model comprises joint 1 and the lock sleeve 3 with internal thread 2, the center of joint 1 offers the water hole 11 of axial perforation, described joint 1 comprises the joint 4 connecting successively, fixing part 5 and water pipe belled part 6, on the outer wall of described fixing part 5, be provided with the outside thread corresponding with the internal thread 2 of lock sleeve 37, described water pipe belled part 6 is taper, on water pipe belled part 6, offer groove 8, in groove 8, be inlaid with expansion sleeve 9, described expansion sleeve 9 is filled up groove 8 and is formed smooth outer wall with water pipe belled part 6, described lock sleeve 3 be screwed on by internal thread 2 on the outside thread 7 of described fixing part 5 with joint 1 form be spirally connected fixing, the thickness of described lock sleeve 3 one end is increased gradually by 2 of internal threads, described fixing part 5 and the joint of water pipe belled part 6 are provided with seal ring 10, described joint 4 is provided with internal thread 2.
Working principle of the present utility model: the utility model is by being divided into joint 4 by joint 1, fixing part 5 and water pipe belled part 6, internal thread 2 is set on joint 4, for possessing and have externally threaded joint to be connected with other, the outside thread 7 corresponding with the internal thread 2 of lock sleeve 3 is set on fixing part 5, fixing part 5 is for fixing and locking cover 3, water pipe belled part 6 is for fixing water pipe to be connected, by expansion sleeve 9 is set on water pipe belled part 6, after the pre-thermal expansion of expansion sleeve 9, to compensate water pipe internal diameter, thereby ensure that water pipe is fixed between lock sleeve 3 and joint 1, prevent from coming off, because the thickness of lock sleeve 3 one end is increased gradually by 2 of internal threads, limiting water pipe expands, further ensure the soundness connecting, by seal ring 10 being set in the joint of fixing part 5 and water pipe belled part 6, improve sealing.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
