Abstract
The utility model discloses a kind of slidable adjustment head, aim to provide a kind of length adjustment convenient, the reliable and slidable adjustment head that connection speed is fast of connection sealing.It comprises one end and has externally threaded first connecting tube, and grafting enters the first connecting tube male end and along the second connecting tube of the first connecting tube movement, can screw the locking nut in the first connecting tube male end, and be arranged at the seal ring in locking nut.The utility model connects fast and reliable, effectively can reduce the difficulty of construction of fracture pipeline rehabilitation.
Description
Technical field
The utility model relates to water pipe joint technical field, especially relates to a kind of convenient adjusting head slided.
Background technique
During existing connection fracture pipeline, it is fixing that one end of pipeline connects rear the other end length, and be difficult to adjustment, the difficulty that pipeline connects is large, and connection procedure comparatively bothers, and the engineering time is long.And the sealing connected is difficult to ensure, connection reliability is not high.
Model utility content
The utility model overcomes shortcoming of the prior art, provides a kind of length adjustment convenient, the reliable and slidable adjustment head that connection speed is fast of connection sealing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of slidable adjustment head, it comprises one end and has externally threaded first connecting tube, grafting enters the first connecting tube male end and along the second connecting tube of the first connecting tube movement, can screw the locking nut in the first connecting tube male end, and be arranged at the seal ring in locking nut.
Preferably, described seal ring is O RunddichtringO.
Preferably, described first connecting tube and/or the second connecting tube are reducer pipe.
Compared with prior art, the utility model tool has the following advantages:
The utility model adjustable length, first section connecting tube of wherein (the first connecting tube and one of both second connecting tubes) one end with fracture pipeline is connected during use, pull again another section of connecting tube by its with fracture pipeline the other end be connected, tighten locking nut afterwards and realize being fixedly connected with of two sections of connecting tubes, realized the sealing of two sections of connecting tubes by locking nut crush seal circle.The utility model connects fast and reliable, effectively can reduce the difficulty of construction of fracture pipeline rehabilitation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of part A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Slidable adjustment head shown in Fig. 1-2, it comprises one end and has externally threaded first connecting tube 1, grafting enters the first connecting tube 1 male end and can along the second connecting tube 2 of the first connecting tube 1 movement, screw the locking nut 3 in the first connecting tube 1 male end, and be arranged at the seal ring 4 in locking nut 3.
Wherein, described seal ring 4 preferably adopts O RunddichtringO.
As further improvement, described first connecting tube 1 and/or the second connecting tube 2 are reducer pipe, to adapt to the connection of different tube diameters pipeline.
The utility model adjustable length, first section connecting tube of wherein (the first connecting tube and one of both second connecting tubes) is connected (be threaded or welding etc.) with one end of fracture pipeline during use, pull another section of connecting tube that it is connected (be threaded or welding etc.) with the other end of fracture pipeline again, tighten locking nut afterwards and realize being fixedly connected with of two sections of connecting tubes, realized the sealing of two sections of connecting tubes by locking nut crush seal circle.The utility model connects fast and reliable, effectively can reduce the difficulty of construction of fracture pipeline rehabilitation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
