Description

Buried maintainable sleev compensator

One, technical field: the utility model relates to a kind of compensation of pipeline device, particularly a kind of buried maintainable sleev compensator.

Two, background technique: the compensation of pipeline device mainly is to solve the problem of expanding with heat and contract with cold that pipeline causes because of temperature variation, eliminates the pipeline internal stress, makes pipe network keep good operating mode.At present, the buried pipeline compensator mainly contains two kinds of forms: the one, and bellow type is buried the ground compensator, and the 2nd, the telescopic ground compensator that buries.The major defect of burying the ground compensator of these two kinds of forms is: not maintainable.After using with burying,, can only excavate ground and carry out technical finesse or change product in case the medium seepage occurs.Moreover, above-mentioned two kinds bury ground compensator bury ground after, can't observe on the ground, if when small medium seepage takes place, be difficult for finding, when finding the medium seepage by the time, pipe network has been caused bigger infringement, bring great hidden danger to pipe network operation.

Three, summary of the invention: the purpose of this utility model is to provide a kind of compensator of can observing on the ground whether the medium seepage is arranged at above-mentioned the deficiencies in the prior art, and can implement the buried maintainable sleev compensator of mending-leakage measure on the ground.

The purpose of this utility model has following mode to realize:

The utility model comprises outer sleeve, the core tube, the internal diameter of outer sleeve is greater than the external diameter of core tube leading portion, the leading portion of core tube is inserted in the outer sleeve, and the core letter be inserted in the end be inserted in outer sleeve after, leave the gap between two barrels, the end that is inserted at the core tube is provided with the anti-ring that pulls out, inwall at outer sleeve is provided with and the anti-corresponding inner baffle ring of ring that pulls out, it is characterized in that: on the outer wall of the right of outer sleeve inner baffle ring outer sleeve, be provided with outer hopper around outer sleeve, have stuffing hole equably on the outer wall that hopper covers outside quilt, hopper is provided with and the corresponding material hole by the bolt shutoff of stuffing hole outside, in the hopper stuffing box packing is housed outside, hopper is provided with the feed supplement pipe outside, the right of hopper is provided with overflow pipe outside on the outer wall of outer sleeve, on the core tube, be with spacer ring with holes on the wall, formed the main stuffing box of ring-type between spacer ring and inner baffle ring, in main stuffing box, stuffing box packing is housed, spacer ring can slide on the core tube, right-hand member at outer sleeve is fixed with the gland that is overlapping the core tube, formed the auxilliary stuffing box of ring-type between spacer ring and gland, in auxilliary stuffing box, stuffing box packing has been housed.

The utility model has the advantages that: need not build well, can directly use with burying, can observe compensator on the ground whether the medium seepage is arranged, and can implement the mending-leakage measure on the ground, not only improved the operational reliability of compensator widely, prolong the working life of compensator, and reduced the maintenance cost of pipe network widely.

Four, description of drawings: Fig. 1 is the structural representation that partly cuts open of the present utility model; Fig. 2 is the left view of Fig. 1.

Five, embodiment: with reference to accompanying drawing, the utility model comprises outer sleeve 1, core tube 16, the internal diameter of outer sleeve 1 is greater than the external diameter of core tube 16 leading portions, the leading portion of core tube 16 is inserted in the outer sleeve 1, and core tube 16 be inserted in the end be inserted in outer sleeve 1 after, leave the gap between two barrels, the end that is inserted at core tube 16 is provided with the anti-ring 2 that pulls out, be provided with and the anti-corresponding inner baffle rings 19 of ring 2 that pull out at the inwall of outer sleeve 1, on the outer wall of the right of inner baffle ring 19 outer sleeve 1, be provided with outer hopper 4 around outer sleeve 1, have stuffing hole 22 equably on the outer wall that hopper 4 covers outside quilt, hopper 4 is provided with and stuffing hole 22 corresponding material holes by bolt 17 shutoff outside, in the hopper 4 stuffing box packing 20 is housed outside, stuffing box packing 20 should be solid-state, and has a good flowable, general employing graphite packing, hopper 4 is provided with feed supplement pipe 6 outside, the right of hopper 4 is provided with overflow pipe 8 outside on the outer wall of outer sleeve 1, on core tube 16, be with the spacer ring 7 that has equally distributed hole 21 on the wall, 19 of spacer ring 7 and inner baffle rings have formed the main stuffing box of ring-type, stuffing box packing 3 is housed in main stuffing box, spacer ring 7 can slide on core tube 16, right-hand member at outer sleeve 1 is fixed with the gland 12 that is overlapping

core tube

16,12 on spacer ring 7 and gland have formed the auxilliary stuffing box of ring-type, in auxilliary stuffing box stuffing box packing 10 are housed.Hopper 4 is provided with oil filler pipe 5 outside, in the oil filler pipe 5 one-way valve should be installed.In order to protect compensator; prevent that compensator from being damaged by silt at work; be provided with sheath 13 at the rear portion of outer sleeve 1; sheath 13 is to be connected with outer sleeve 1 usefulness bolt 18 by the sheath support 9 that is contained on the outer sleeve 1; on the outer wall at core tube 16 rear portions, be provided with all seal grooves 14; be provided with stuffing box packing 15 in seal groove 14, flexible gasket is adopted in stuffing box packing 15, for example: rubber or foaming stuffing box packing etc.

During use, the front end of outer sleeve 1 is connected with pipeline respectively with the rear end of core tube 16 and is embedded in underground, feed supplement pipe 6, oil filler pipe 5,7 of spill pipes all are introduced on the ground, resistance in the time of can reducing the injection filler by oiling in the oil filler pipe 5 outside hoppers 4, in main stuffing box, inject stuffing box packing by material hole on the outer hopper 4 and stuffing hole 22, and by injecting stuffing box packing in the feed supplement pipe 6 outside hoppers 4, after outer hopper 4 is filled with, under the effect of injection pressure, stuffing box packing enters in the main stuffing box by stuffing hole 22 again, and promotion spacer ring 7 slides to the right, with the sealing of the stuffing box packing compacting in the auxilliary stuffing box on its right side, the also sealed filler of main stuffing box on spacer ring 7 left sides filled up and sealed this moment until spacer ring 7.When pipe network because of temperature variation cause expand with heat and contract with cold the time, the outer sleeve 1 of compensator is made slide relative with core tube 16, thereby has eliminated the pipeline internal stress, has guaranteed the normal operation of pipe network.When compensator generation seepage, the medium that leaks out enters spill pipe 7 along slit between spacer ring 7 and sleeve and the hole on the spacer ring 21, the staff just can find seepage, and the staff carries out the feed supplement sealing by feed supplement pipe 6 on the ground then, makes compensator recover normal working state.
