Embodiment
See Fig. 1-2, show clad type pipe joint of the present invention.
This clad type pipe joint at least comprises middleware 11, supporter 12, fastening piece 13 and resiliency deformable member 14.
Described middleware 11 is the main body connecting both sides pipe fitting T, it comprises the transition part 111 being positioned at pipe fitting T intermediate gaps position, both sides and the first jut 113 upwards extended from two ends, in order better to provide, pipe fitting T's enter with coated, in the middle of the internal surface of described middleware 11, both sides are extended the covering portion 112 inserted inside described pipe fitting T respectively laterally by transition part 111, wherein, the extension of described both sides covering portion 112 is to concordant with the end at middleware 11 two ends.
Thus, when both sides pipe fitting T connects, pipe fitting T is only needed to insert in the space between covering portion 112 and middleware 11 main body, stable position can be become to pipe fitting T-shaped, need not manually adjust pipe fitting T position and insertion depth, easier for installation, because the length of covering portion 112 is identical with the length of main body, formed comprehensively coated to an entirety of pipe fitting T, on the one hand can more quick and precisely when inserting, the degree of depth also achieved on the other hand in pipe fitting T is inserted.
For realizing better sealing effect, sealing configuration is provided with in described middleware 11, described sealing configuration comprises at least one sealed groove laid respectively on both sides covering portion 112 outer wall and at least one sealed groove be positioned on the inwall of middleware 11 main body both sides, is provided with seal ring in described sealed groove.
Thus, the seal ring in middleware 11 main body inner wall seals tube wall, and the seal ring on covering portion 112 outer wall seals inboard wall of tube body, when pipe fitting inserts lock ring, pipe fitting T inside and outside wall is equipped with sealing configuration, carries out effective sealing.
Preferably, described middleware 11 main body both sides inwall is respectively equipped with the first sealed groove 114 and the second sealed groove 115 from outside to inside, and accommodate the first seal ring 15 and the second seal ring 16 respectively, described covering portion 112 outer wall is respectively equipped with the 3rd sealed groove 116 and the 4th sealed groove 117 from outside to inside, and accommodate the 3rd seal ring 17 and the 4th seal ring 18 respectively, the diameter of described first sealed groove 114 is one times of the second sealed groove 115, and the diameter of the first seal ring 15 is one times of the diameter of the second seal ring 16, the diameter of described 3rd sealed groove 116 is one times of the 4th sealed groove 117, and the diameter of the 3rd seal ring 17 is one times of the 4th seal ring 18, thus, by the sealing that such size combines, effective cascade sealing configuration can be formed, by test, this sealing configuration improves 10% than the sealing effect of the sealing configuration of conventional twice same structure.
Supporter 12 and fastening piece 13 is respectively equipped with outside the two ends of described middleware 11, the inner side of described supporter 12 is provided with second jut 121 relative with the first jut 113, described second jut 121 equally upwards extends, the outside of described supporter 12 is provided with to downward-extension and is resisted against the extension part 123 of described pipe fitting T outer rim, and the below of described second jut 121 forms containing groove 122.
Wherein, the formation inclined-plane, side of described first jut 113 so that carry out extruding and stressed, opposite side can form vertical surface so that carry out against.
The formation inclined-plane, side of described second jut 121, so that carry out extruding and stressed, opposite side also can form inclined-plane or vertical surface.
Wherein, described fastening piece 13 is coated on described first jut 113 and the second jut 121 outer rim, close for what provide between middleware 11 and supporter 12, described fastening piece 13 comprises the transverse slat 131 of cross setting and the first swash plate 132 and the second swash plate 133 of extension of tilting respectively to outside from transverse slat 131 two ends, the angle of inclination of described first swash plate 132 is identical with the angle of inclination on the first jut 113 inclined-plane, be posted by the inclined-plane of described first jut 113 to make the first swash plate 132, the angle of inclination of described second swash plate 133 is identical with the angle of inclination on the second jut 113 inclined-plane, be posted by the inclined-plane of described second jut 121 to make the second swash plate 133, thus, be pressed against in process, the cooperatively interacting of inclined-plane can provide larger near power, mutually reclining of inclined-plane can guarantee uniform force simultaneously.
See Fig. 2, described fastening piece 13 is opening member, its opening end is respectively equipped with the first engagement portion 134 and the second engagement portion 135 upwards extended, described first engagement portion 134 is relative with on the second engagement portion 135 is provided with through hole, and clamping bolt 136 and lock ring nut 137, coordinate with tightening nut after described clamping bolt 136 runs through the through hole of described first engagement portion 134 and the second engagement portion 135 and carry out lock ring, to be strained by fastening piece 13.
Also be provided with resiliency deformable member 14 between described middleware 11 and supporter 12, the rear end of described resiliency deformable member 14 is inserted in described containing groove 122, and front end extends upward the 3rd jut 141 be positioned at below described first jut 113.
Thus, the present invention in an installation, first be linked on the first jut 113 and the second jut 121 by fastening piece 13, then the pipe fitting T of both sides is inserted the covering portion 112 of middleware, again the cooperation of clamping bolt and tightening nut is compressed, force supporter 12 close to middleware 11, thus the resiliency deformable member 14 in the middle of compressing is out of shape, to fit tightly in pipe fitting T outer rim, obtain good sealing effect.
The inwall of described resiliency deformable member 14 is provided with at least one semi-circular projection, preferably, is provided with the first semi-circular projection 142 and the second semi-circular projection 143, when being out of shape, by the setting of semi-circular projection, avoid laminating distortion during resiliently deformable, can better gluing, sealing be carried out.
Those of skill in the art would appreciate that the material of described resiliency deformable member 14 can be quality of rubber materials, its main material can be neoprene or isoprene rubber, thus, makes resiliency deformable member have good elasticity, also has winter hardiness and wear resistance.
The invention has the advantages that:
1, structure is simple, and it is convenient, easy to operate to coordinate, and can realize the quick connection between pipe;
2, accurate stable is connected, good connecting effect;
3, achieve multiple fitted seal between pipe, sealing effect effectively improves, and avoids managing releasing of interior object, improves working life.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the present invention do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of specification and the appended claim fallen into above.
