Detailed description of the invention
See Fig. 1, it is shown that the earth's surface shallow embedding formula pipe connecting structure of the present invention.
This earth's surface shallow embedding formula pipe connecting structure mainly comprise pipe connections and embedment pipe, described in bury
Entering pipe 20 is bimetal pipe, and it comprises inner tube 201 and is sleeved on inner tube 201 outer rim
Outer tube 202, wherein, said inner tube 201 can be steel pipe, and described outer tube 202 closes for copper chromium
Jin Guan, with in the preferable elastic foundation keeping copper, improves the corrosion resistance of outer tube and resistance to
Mill property.
Wherein, the inwall of said inner tube 201 is coated with anti-corrosion resin coating, wherein, described
The end outer rim of outer tube 202 is provided with progressive lobe, and described progressive lobe is from away from end
Certain distance starts gradually to extend perpendicularly outward, the most progressive end that is raised to, described gradually
Enter lobe and provide a progressive raised position at the two ends of whole pipe connecting structure,
When installing between the two tubes or fix, due to the extruding of pipe connections, described gradually
Enter lobe by squeezed press to outside end slightly protruding, thus preferably carry out
Seal and laminating, make end sealing effect during installation more preferable.
Seeing Fig. 2 and Fig. 3, described pipe connections is including at least holding part 11 and elastic pressure tightly
Contracting ring 12, described in hold part 11 tightly for open annular and cross section be U-shaped shown in Fig. 2,
Described elastic compression ring 12 holds part 11 inner edge tightly described in being positioned at.
Wherein, in order to coordinate the progressive lobe of described outer tube 202, described elastic compression ring
The inner edge of 12 is provided with the first depression 121 and the second depression 122, described first depression 121
It is respectively symmetrically with the second depression 122 and is positioned at both sides, middle part, described first depression 121 and the
The 1/2-3/2 that the degree of depth is described elastic compression ring 12 thickness of two depressions 122, width is
1-3mm。
Thus, described first depression 121 and the second depression 122 are pressed at elastic compression ring 12
Necessary extendable room is provided during contracting, ensure that the compressive strength of elastic compression ring simultaneously.
Described part 11 of holding tightly is provided with pulling assembly, described pulling assembly comprise turnbuckle 16,
Bar 17 is fixed on left fixing bar 15 and the right side, and bar 15 is fixed on a described left side and bar 17 is fixed respectively in the right side
The opening both sides of part 11, the middle part of described left retainer ring 15 is held tightly described in being fastened transversely to
Being provided with the through hole through for described turnbuckle 16, the middle part of described right retainer ring 17 sets
There is the female thread solid for described turnbuckle 16 spiral shell.
Thus, bar is fixed with the right side after running through left fixing bar 15 by the screw rod of turnbuckle 16
The female thread screw-tightened of 17, the distance energy between bar 17 is fixed on left fixing bar 15 and the right side
Carry out close to each other and away from, promote the opening holding part 11 tightly to zoom in or out, thus position
Elastic compression part 12 in holding part 11 tightly is compressed against the interface of nearly two pipes simultaneously,
By described first depression 121 and the compression stroke of the second depression 122 and line up
Press-in, makes two mouths of pipe be attached and seal.
For providing the fixing bar 15 in a left side and the right side to fix the fixing of bar 17, can be by welding or bolt
The mode such as fixing is fixed, it is possible to as it is shown in figure 1, bar 15 is fixed on a described left side and the right side is solid
Fixed pole 17 by coating member be fixedly welded on described in hold the outside of part 11 tightly.
Wherein, described elastic compression ring 12 be respectively provided on two sides with sealing ring, described sealing
Ring is made up of multiple spaced diaphragm seals, and the plurality of diaphragm seal shape is identical and depends on
Secondary connection, it is preferred that can be attached by the elastic strip of through multiple stators.
Seeing Fig. 4, described sealing ring comprises rigid member 13 and is coated with rigid member 13 periphery
Rubber sleeve 14, the periphery coating anti-corrosion resin coating of described rubber sleeve 14, thus, in pressure
During contracting, rubber sleeve 14 provides certain elastic compression equally, it is to avoid to rigid member 13
Directly compressing and destruction.
For improving sealing effectiveness, the inner edge of described rubber sleeve 14 is sequentially provided with height from the inside to the outside
Multiple grooves that degree and width are gradually increased, by the setting of this groove, can realize one
Kind be referred to as breathing the effect sealed, in continuous compaction process, internal gas and other
Fluid can be discharged by the setting of this multiple grooves, thus reaches better seal
Effect.
Seeing Fig. 4, the plurality of groove is preferably four grooves, the respectively first groove
141, the second groove the 142, the 3rd groove 143 and the 4th groove 144, a described groove
141, the spacing of the second groove the 142, the 3rd groove 143 and the 4th groove 144 is equal
And depth and width are for being gradually increased setting.
Wherein, the initial condition of described elastic compression ring 12 and sealing ring (is alternatively referred to as put
Pine state) under internal diameter more than the external diameter of described embedment pipe 20, can will bury when connecting
Enter pipe 20 and put into elastic compression ring 12 and sealing ring.
When being attached, imbed in pipes 20 insert connector and keep the end of pipe by two
Aliging in portion, is screwed into right fixing bar 17 after turnbuckle 16 inserts left fixing bar 15, logical
Cross the screw action of turnbuckle 16 to make right fixing bar 17 fix bar 15 to the left to move, from
And driving is held part tightly and is carried out inside contracting motion, owing to sealing ring and elastic compression ring 12 are held tightly
Part 11 drives and is compressed, due to interior two depressions of elastic compression ring 12 and outer tube 202
Progressive lobe cooperate, it is achieved closely cooperate, simultaneously the sealing ring of the left and right sides
Not only provide the compression effectiveness of elastic compression ring 12 both sides, moreover it is possible to progressive to outer tube 202
Lobe is carried out against, it is to avoid both disengagings.
It is an advantage of the current invention that:
1, simple in construction, cooperate facility, easy to operate, and can realize between pipe is fast
Speed connects；
2, accurate stable is connected, it is to avoid depart from, good connecting effect；
3, the connection between pipe seals more preferably, it is to avoid releasing of the interior object of pipe, thus avoids
Corrosion and destruction to connector, improves service life.
It is readily apparent that above description and record are only to illustrate rather than in order to limit
The disclosure, apply or use.Although describing the most in an embodiment also
And be described in the drawings embodiment, but the present invention is not intended to by accompanying drawing example and is implementing
