Abstract
The utility model discloses a kind of composite tube joint, comprise supervisor, arm, arm is connected on supervisor, one end of supervisor is provided with inipple, inipple inwall is stepped, inipple include three be connected and internal diameter the first threaded pipe, the second threaded pipe and the 3rd screwed pipe that increase successively, threaded pipe is provided with the annular groove of depression, is provided with elastic seal ring in annular groove.The utility model overcomes the pipe fitting that existing pipe joint directly can not connect different tubular, various outer diameter, provides a kind of reduction nipple that directly can connect different tubular, various outer diameter pipe fitting.
Description
Technical field
The utility model belongs to pipe joint field, is specifically related to a kind of reduction nipple being applicable to different mouth of pipe specification.
Background technique
Pipe joint is parts conventional in pipeline, and it plays connecting tube, changes direction, picks out the effects such as pipeline.At present, when pipe joint needs to connect difform pipeline, during as wanted connecting circular tube and square tube, common pipe joint cannot realize, and only has and designs one set of die separately, will increase the cost of pipe joint like this.At present, pipe joint is that the pipe fitting model the most frequently used for this neighborhood designs internal diameter of pipe joint according to application neighborhood.When internal diameter of pipe joint does not mate with tube outer diameter, existing way is between pipe joint and pipe fitting, set up a reducer union, and it not only increases construction cost and operation easier, also makes linkage structure more complicated.
Model utility content
The technical problems to be solved in the utility model is above-mentioned 2 deficiencies for prior art, provides a kind of pipe joint that directly can connect different tubular, various outer diameter pipe fitting.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: composite tube joint, comprise supervisor, arm, arm is connected on supervisor, one end of supervisor is provided with inipple, and inipple inwall is stepped, inipple include three be connected and internal diameter the first threaded pipe, the second threaded pipe and the 3rd screwed pipe that increase successively, threaded pipe is provided with the annular groove of depression, is provided with elastic seal ring in annular groove.
Adopt the composite tube joint of technical solutions of the utility model, threaded pipe is the field of applying by pipe joint, as automotive field, daily water consumption field, according to conventional tube outer diameter size, determine threaded pipe quantity, as the first threaded pipe, the second threaded pipe, the 3rd threaded pipe etc., then the position of threaded pipe at inipple inwall is set.Different threaded pipe internal diameters can realize composite tube joint and connect various outer diameter pipe fitting.Due in the annular groove that is provided with on threaded pipe, thicker elastomer seal circle is installed, and elastic seal ring axially can be extruded, so the pipe joint of this kind of structure can realize good sealing.
Working principle of the present utility model is: when pipe joint connects various outer diameter pipe fitting, pipe fitting is first pushed to the maximum threaded pipe of tapered thread joint internal diameter by operator, i.e. the 3rd threaded pipe, firmly rotate fixing again, if threadingly pipe fitting outwards firmly can be pulled up by tube axis line direction, then do not match corresponding threaded pipe.Now again pipe fitting is pushed to second largest threaded pipe of tapered thread joint internal diameter, i.e. the second threaded pipe, by that analogy, until threadingly pipe fitting outwards firmly can not be pulled up by tube axis line direction, then match corresponding threaded pipe.Pipe fitting is connected with supervisor by threaded pipe, and pipe fitting and elastic seal ring phase mutual active force, make pipe fitting can be fixedly connected with supervisor, seal.
The beneficial effects of the utility model are: threaded pipe pipe joint being provided with varying number, different inner diameters according to practical situations, can directly connect the pipe fitting of various outer diameter, without the need to setting up reducer union, linkage structure is simple, compact, reduces construction cost and operation easier simultaneously.
Further, the transverse section of described annular groove is that triangle or rectangle are trapezoidal or circular, and figure is various, flexible design.
Further, described arm is vertical with supervisor, supervisor is provided with welding hole, welding hole edge is provided with the turnup structure of vertical supervisor to varus, when pipe joint arm is welded with welding hole, pipe joint branch pipe welding on turnup structure wall, thus increases supervisor and the efficient weld area of arm, increases weld strength.During Design Supervisor's welding hole shape, design according to arm transverse shape, as circular, square, achieve the connection of different tubular with this, as pipe and square tube; Or the connection between special cast, as square tube and square tube.
Further, described inipple is one-body molded with supervisor, and inipple is tapered, saves material, saves cost.
Further, described inipple outer wall is provided with elastic insert, plays damping, moistureproof effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the generalized section of the utility model composite tube joint embodiment one,
Fig. 2 is the left view of the utility model composite tube joint embodiment one,
Fig. 3 is the left view of the utility model composite tube joint embodiment two,
Fig. 4 is the generalized section of the utility model composite tube joint embodiment three.
Embodiment
Embodiment one:
As depicted in figs. 1 and 2, the utility model composite tube joint, comprises supervisor 1, arm 2, and arm 2 is vertical with supervisor 1, and supervisor 1 is provided with welding hole, and welding hole edge is provided with the turnup structure 3 of vertical supervisor to varus; One end of supervisor 1 is provided with and is responsible for 1 integrated tapered thread joint 4, tapered thread joint 4 include three be connected and the first threaded pipe 51, second threaded pipe 52 of increasing successively of internal diameter and the 3rd screwed pipe 53; Threaded pipe 5 is provided with the annular groove 6 of depression, is provided with elastic seal ring 7 in annular groove 6; Tapered thread joint 4 outer wall is provided with elastic insert 8.
In specific implementation process, supervisor 1, arm 2 transverse section are circle, and be responsible for 1 wall thickness 1mm, the height of turnup structure 3 is 3mm, and the welding hole on supervisor 1 is circular, by welding, realizes the connection of pipe and pipe.According to conventional tube outer diameter size, determine the quantity of threaded pipe 5, as the first threaded pipe 51, second threaded pipe 52, the 3rd threaded pipe 53 etc., then the position of threaded pipe 5 at inipple inwall is set.
Embodiment two:
As shown in figures 1 and 3, embodiment two is with the difference of embodiment one: be that to replace with transverse section be square supervisor 1 to circular supervisor 1 by the transverse section in embodiment one.Welding hole on such supervisor 1 is the circular hole on square planar, compares embodiment one, and the implementation procedure of welding hole is more simple.
Embodiment three:
As described in Figure 4, embodiment three is with the difference of embodiment one: the two ends being responsible for 1 in embodiment three are equipped with inipple 4.In concrete implementation and operation, the pipe fitting of inipple 4 one end adopts right-handed spiral to connect, and the pipe fitting of the other end adopts left-handed spiral to connect, and is connected more firm respectively with the pipe fitting that this realizes inipple 4 two ends with pipe joint.
For a person skilled in the art; under the prerequisite not departing from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
