Abstract
The utility model discloses a cross-wall sleeve for waterproof and sealing object when a pipe goes through a wall. The cross-wall sleeve can be widely applied on a pipe system used in heat supply field, metallurgy field, petrochemical field and architectural field. The cross-wall sleeve comprises a fluid pipe, a baffle ring I, a baffle ring II, a pushing connection tube I', a pushing connection tube II', an outer sleeve, a support ring and a corrugated pipe. The well room is completely separated into an inner room and an outer room by the corrugated pipe, the baffle ring I, the baffle ring II, the pushing connection tube I' and the pushing connection tube II', so that the wall is flexible connected with the pipe. Once a displacement is happened to the pipe caused by expansion, the corrugated pipe disposed in the cross-wall will compensate the displacement to adjusting the position of pipe to avoid moving gap between the pipe and the wall, so as to avoid attack from the pipe to the wall. Therefore, by using the cross-wall, a wall crack situation is avoided and a waterproof and sealing object is achieved.
Description
Technical field
The utility model relates to a kind of wall sleeve of crossing, and it is applicable to waterproof and sealing when the medium transport pipeline is crossed wall, can be widely used in the pipe-line system of industries such as heat supply, metallurgy, petrochemical industry, building.
Background technique
At present, when the medium transport pipeline is crossed wall, for preventing that extraneous water from entering the well chamber, the general solution of available technology adopting is between pipeline and body of wall annular sealed chamber to be set, fill up asbestos packing or cushion rubber in the closed chamber, with gland it is compressed, make not have the gap between body of wall and pipeline, play the purpose of anti-seep water.Although this structure can play the anti-seep water effect within a certain period of time, but compress inoperative or generation displacement movement because pipeline expands with heat and contract with cold when service time is long, when the slit appearred in sealing part, it is indoor that extraneous water can enter well, influences the conventional maintenance and the operation of pipeline.
Summary of the invention
The objective of the invention is to provide a kind of simple in structure, sealed waterproof effect good, the medium transport pipeline of protecting long service life is crossed wall waterproof locking device---cross wall sleeve.
The purpose of this utility model is achieved in that this crosses wall sleeve and comprise fluid hose, baffle ring I, II, thrust is taken over I ', II ', outer sleeve, support ring, bellows, its bellows is arranged on the fluid hose outside, bellows one end is taken over I ' with thrust and is connected, be connected with outer sleeve again after thrust is taken over I ' and baffle ring I is connected, have the free gap between baffle ring I and the fluid hose; The bellows the other end is taken over II ' with thrust and is connected, and thrust adapter II ' is connected with baffle ring II and is connected with fluid hose is outside; Take over II ' outside in thrust and be with support ring, thrust is taken between II ' and the support ring and is left the free gap, and the support ring outer ring is connected with outer sleeve.
Described outer sleeve is provided with stop ring.
The utility model is owing to adopt said structure to have the following advantages:
1, the utility model leans on the enclosed construction form of packing or cushion rubber to become the steel part enclosed construction form with flexibility original anti-hydrophone, avoided generation displacement movement because pipeline expands with heat and contract with cold, when the slit appears in sealing part, it is indoor that extraneous water can enter well, influence the conventional maintenance of pipeline and the drawback of operation, reached the effect of sealing fully.
2, the steel part structure that the utility model adopted can reach and the effect of pipeline with the life-span.
Description of drawings
Fig. 1 was a wall sleeve overall structure schematic representation.
Embodiment
This is crossed wall sleeve and comprises fluid hose 1, baffle ring I, II, thrust is taken over I ', II ', outer sleeve 2, support ring 3, bellows 4, bellows 4 is enclosed within fluid hose 1 outside of fed sheet of a media, two ends welding thrust is taken over I ', II ', one end thrust is taken over I ' and is welded with outer sleeve 2 with baffle ring I welding again, and 1 of baffle ring I and fluid hose have free gap 6; The other end thrust is taken over II ' and baffle ring II and is welded and fluid hose 1 outside weldings again; Take over II ' outer cover upper support ring 3 in thrust, leave free gap 7 therebetween, support ring 3 outer rings and outer sleeve 2 welding; Stop ring 5 also welds on outer sleeve 2 outer cover, so far finishes the course of working of wall water string.
This structural feature of crossing wall sleeve is: bellows 4, baffle ring I, baffle ring II, thrust are taken over I ', thrust is taken over II ' the indoor outside of well is cut off fully; The two ends of fluid hose 1 and main pipeline are welded to connect during application, stop ring 5 is built with the body of wall of well chamber with outer sleeve 2 and is in the same place, forming body of wall and pipeline enclosure flexibly connects, when pipeline had the generation of expansion displacement, the bellows of crossing in the wall sleeve 4 can compensate, and displacement is absorbed, can not produce movement clearance between assurance and body of wall, avoided the impact of pipeline, prevented that the crack from appearring in body of wall, played the effect of waterproof sealing body of wall.
