Abstract
The utility model relates to a direct -burried combined type sleeve compensator is equipped with bellows and outer sleeve in the periphery of ordinary sleeve compensator, and the bellows comprises left and right bellows, and its inner chamber sealing chamber is connected with valve, manometer or sensor through the control connecting leg. The utility model discloses the dependable performance, the leakage takes place in case the compensator packs for long service life, can promptly and accurately seek and confirm concrete position, reduces maintenance cost and work load, and the long -term high efficiency operation of protection heating power pipe network improves economy and social, is favorable to the environmental protection.
Description
Technical field
The utility model relates to pipeline compensator, especially a kind of direct-burried Combined socket compensator for directly buried heating pipeline system.
Background technique
When city directly buried heating pipeline system delivering vapor, hot water or high-temperature water medium, expand with heat and contract with cold because pipeline affects formation by medium temperature, the common compensator of straight-embedded socket compensate for displacement of general employing.Common compensator of straight-embedded socket is formed primarily of shell, stuffing box packing and connecting end pipe, and it compensates the expand with heat and contract with cold displacement that produces of pipeline and realizes by the dilatation of sleeve expansion joint.Due to the dilatation of sleeve expansion joint, stuffing box packing wearing and tearing or thermal stress can be produced cause telescopic core pipe coaxality to exceed standard to cause bias under certain cycle, easily to leak, compensator of straight-embedded socket is embedded in underground once leak the particular location and leakiness that cannot search and judge to leak, cause whole pipeline again to be ditched to search, not only operating cost is high, large size also can be caused to stop vapour, affect user normally to produce, city image is affected when traversing pipe line urban district and highway, block traffic, environment and greening are damaged, directly affect economic benefit and social benefit.
Model utility content
The purpose of this utility model is the deficiency overcoming existing directly buried pipeline sleeve expansion joint, provides one to be applicable to High Temperature High Pressure directly buried heating pipeline system, is convenient on the spot and remote monitoring, long service life, the direct-burried Combined socket compensator that operating cost is low.
The purpose of this utility model is achieved through the following technical solutions:
Direct-burried Combined socket compensator, comprise end pipe, telescopic pipe and stuffing box packing, its improvements are arranged with bellows at end pipe and the outer of telescopic pipe, bellows has outer sleeve, the two ends of bellows have the fixed charge method end plate be connected on end pipe and outer sleeve and the slip end plate be connected on telescopic pipe respectively, bellows inner chamber forms closed chamber, and described fixed charge method end plate is provided with the ground monitoring connecting leg with bellows inner space.
Described bellows is made up of left and right bellows, and there is supporting sleeve joint, and left and right bellows design parameter is identical; The outlet end of described ground monitoring connecting leg is connected with valve, pressure gauge or sensor; Described slip end plate becomes sliding type to contact with supporting sleeve and outer sleeve, restraining position ring block on the outer sleeve inwall outside slip end plate.
In the utility model, bellows forms closed chamber to sleeve expansion joint, be in passive state at ordinary times, supplement and Exhaust Gas by ground monitoring connecting leg when bellows compression or extensional motion, once sleeve expansion joint filler occurs to leak transmit pressure by ground monitoring connecting leg to pressure gauge or sensor, can realize monitoring on the spot and remote monitoring by pressure gauge or sensor display, remind and guide operating personnel to keep in repair in time, accurately, greatly alleviating workload, improve economic and social benefit.
Described bellows forms by two, can avoid a long phenomenon causing unstability of bellows.Two various design parameters of bellows are identical, can equilibrium bear deformation-compensated.The times of fatigue of the utility model bellows used is that sleeve expansion joint stretches more than 10 times of number of times, even if sleeve expansion joint leaks, by monitoring, close the valve on ground monitoring connecting leg, bellows also can effectively keep pipeline pressure to work on.
Direct-burried combined type cover compensator reliable performance of the present utility model, applied range, Maximum operating temperature can reach 350 DEG C, and Maximum operating pressure can reach 6.0Mpa, and maximum axial compensation rate can reach 400mm, can ensure the long-term Effec-tive Function of directly buried heating pipeline system.
The utility model is 4 ~ 6 times of existing common direct-burried compensator working life; compensation ability is 2 ~ 4 times of existing common direct-burried compensator; the maintenance of the secondary of direct-burried heating power power conduit and regular maintenance cost are reduced greatly; save operating cost more than 60%; increase economic efficiency, be conducive to environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The right bellows 9 of 1 end pipe 2 ground monitoring connecting leg 3 fixed charge method end plate 4 left bellows 6 telescopic pipe 7 supporting sleeve 8 of outer sleeve 5 slides the stuffing box packing of end plate 10 limited ring 11.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, direct-burried Combined socket compensator comprises end pipe 1, telescopic pipe 6 and stuffing box packing 11, the bellows be made up of left bellows 5 and right bellows 8 is arranged with outside it, bellows has outer sleeve 4, bellows two ends have the fixed charge method end plate 3 be connected on end pipe 1 and overcoat 4 and the slip end plate 9 be connected on telescopic pipe 6 respectively, bellows inner chamber forms closed chamber, fixed charge method end plate 3 is provided with the ground monitoring connecting leg 2 with bellows inner space, left, there is supporting sleeve 7 right bellows joint, supporting sleeve becomes sliding type to contact with slip end plate and outer sleeve, outer sleeve right-hand member restraining position ring block 10.
Direct-burried Combined socket compensator and supervisory system with the use of, left bellows is connected with valve, pressure gauge or sensor by ground monitoring connecting leg with right sylphon seal room, can realize monitoring on the spot and remote monitoring.Left bellows and right bellows, have the identical design parameter such as wave height, the pitch of waves, wave number, wall thickness, the ripple number of plies, bearing capacity, compensation rate, fatigue life.
