Embodiment
See Fig. 1, show earth's surface shallow embedding formula pipe connecting structure of the present invention.
This earth's surface shallow embedding formula pipe connecting structure mainly comprises tubular union and imbeds pipe, described pipe 20 of imbedding is for bimetal pipe, its outer tube 202 comprising interior pipe 201 and be sleeved on interior pipe 201 outer rim, wherein, described interior pipe 201 can be steel pipe, described outer tube 202 is chromiumcopper pipe, with in the better elastic base keeping copper, improves corrosion resistance and the wear resistance of outer tube.
Wherein, the inwall of described interior pipe 201 is coated with anti-corrosion resin coating, wherein, the end outer rim of described outer tube 202 is provided with progressive lug boss, described progressive lug boss is from Vertical dimension extension gradually apart from end certain distance, always progressively be raised to end, described progressive lug boss provides a progressive raised position at the two ends of whole pipe connecting structure, carry out between the two tubes installing or fixing time, due to the extruding of tubular union, described progressive lug boss is protruding by what to be extruded outside end slightly, thus better carry out sealing and fitting, make end sealing better effects if during installation.
See Fig. 2 and Fig. 3, described tubular union at least comprises holds part 11 and elastic compression ring 12 tightly, described in hold part 11 tightly for open annular and U-shaped for shown in Fig. 2 of cross section, hold part 11 inner edge described in described elastic compression ring 12 is positioned at tightly.
Wherein, in order to coordinate the progressive lug boss of described outer tube 202, the inner edge of described elastic compression ring 12 is provided with the first depression 121 and the second depression 122, described first depression 121 and the second depression 122 respectively symmetry are positioned at both sides, middle part, the degree of depth of described first depression 121 and the second depression 122 is the 1/2-3/2 of described elastic compression ring 12 thickness, and width is 1-3mm.
Thus, described first depression 121 and the second depression 122 provide necessary extendable room when elastic compression ring 12 compresses, ensure that the compression strength of elastic compression ring simultaneously.
Described part 11 of holding tightly is provided with pulling assembly, described pulling assembly comprises turnbuckle 16, left fixing rod 15 and right fixing rod 17, the opening both sides of part 11 are held tightly described in described left fixing rod 15 and right fixing rod 17 are laterally fixed on respectively, the middle part of described left retaining ring 15 is provided with for the through through hole of described turnbuckle 16, and the middle part of described right retaining ring 17 is provided with for the solid internal thread of described turnbuckle 16 spiral shell.
Thus, the internal thread screw-tightened with right fixing rod 17 after left fixing rod 15 is run through by the screw rod of turnbuckle 16, distance between left fixing rod 15 and right fixing rod 17 can carry out close to each other and away from, the opening holding part 11 tightly is impelled to reduce or amplify, thus by the interface of compression near two pipes while of being positioned at the elastic compression part 12 holding part 11 tightly, by described first depression 121 and the second depression compression volume of 122 and press-in of line up, two mouths of pipe are made to carry out connecting and sealing.
For providing the fixing of left fixing rod 15 and right fixing rod 17, by welding or bolt is fixing etc. that mode is fixed, also as shown in Figure 1, the outside of part 11 described in described left fixing rod 15 and right fixing rod 17 are fixedly welded on by coating member, can be held tightly.
Wherein, the both sides of described elastic compression ring 12 are respectively equipped with seal ring, and described seal ring is made up of multiple spaced diaphragm seal, and described multiple diaphragm seal shape is identical and connect successively, and preferably, the elastic strip by through multiple fixed plate connects.
See Fig. 4, described seal ring comprises the rubber sleeve 14 of rigid pipe 13 and coated rigid pipe 13 periphery, the periphery coating anti-corrosion resin coating of described rubber sleeve 14, thus, when compressing, rubber sleeve 14 provides certain elastic compression equally, avoids the direct compressing to rigid pipe 13 and destruction.
For improving sealing effect, multiple grooves that inner edge is provided with highly from the inside to the outside successively and width increases gradually of described rubber sleeve 14, by the setting of this groove, a kind of effect being called breathing sealing can be realized, in continuous compaction process, inner gas and other fluids are discharged by the setting of this multiple groove, thus reach better sealing effect.
See Fig. 4, described multiple groove is preferably four grooves, be respectively the first groove 141, second groove 142, the 3rd groove 143 and the 4th groove 144, the spacing of described groove 141, second groove 142, the 3rd groove 143 and the 4th groove 144 equal and the degree of depth and width are for increase setting gradually.
Wherein, described in the internal diameter under the reset condition (also can be described as relaxation state) of described elastic compression ring 12 and seal ring is greater than, imbed the external diameter of pipe 20, so that elastic compression ring 12 and seal ring can be put into by imbedding pipe 20 when connecting.
When connecting, two are imbedded the end part aligning that pipe 20 inserts also holding tube in link, right fixing rod 17 is screwed into after turnbuckle 16 is inserted left fixing rod 15, by the screw action of turnbuckle 16 make right fixing rod 17 left fixing rod 15 move, thus drive and hold part tightly and carry out inside contracting motion, held tightly part 11 driving due to seal ring and elastic compression ring 12 to compress, because the progressive lug boss of interior two depressions of elastic compression ring 12 and outer tube 202 cooperatively interacts, realization closely cooperates, the seal ring of the left and right sides not only provides the compression effectiveness of elastic compression ring 12 both sides simultaneously, can also to the progressive lug boss of outer tube 202 carry out against, avoid both disengagings.
The invention has the advantages that:
1, structure is simple, and cooperatively interact facility, easy to operate, can realize the quick connection between pipe;
2, connect accurate stable, avoid departing from, good connecting effect;
3, the connection sealing between pipe is better, avoids managing releasing of interior object, thus avoids the corrosion to link and destruction, improve 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.
