Abstract

The utility model discloses a filling compensator. It is composed of a ball head, an outer casing, a spherical bush, a sealing ring, an injecting hole, an injecting hole sealing bolt, aquaseal, a backseat, a convex core pipe, a telescopic outer casing, a guiding bush, an outer shell of the corrosion preventing guiding bush, a supporting ring, a supporting ring sealing ring, a protective envelope and a sphere. The corrosion preventing spherical bush is inserted in the outer casing which forms the seal cavity with the sealing ring and the sphere. The aquaseal is injected from the injecting hole. The injecting hole is sealed up by the injecting hole sealing bolt. One end of a pipe is welded on the backseat, and the other end is welded on the ball head. The sealing ring is embedded on the outer side of the convex core pipe. The guiding bush and the outer shell of the corrosion preventing guiding bush are arranged in the two sides of the ring. The telescopic outer casing is installed on the lateral of the ring. The seal cavity is formed. The aquaseal is injected from the injecting hole. One end of the pipe is welded with the backseat, the other end is welded with the convex core pipe. A full buried filling sleeve compensator is basically same as the convex core sleeve compensator, and it only adds a sealing ring and a protective envelope on the convex core pipe. The filling compensator has favorable sealing effect, and it has no leakage and few occupation of land.

Description

The filling type compensator

Affiliated technical field

The utility model relates to a kind of filling type compensator, specifically is that pipeline mediums such as deep fat, hot water, steam are carried special supporting filling type compensator.

Background technique

At present, known compensator has Buddhist abbot's type compensator, ordinary cartridge compensator, corrugated expansion joint etc., and Buddhist abbot's type compensator is a kind of natural compensation method, in certain section of pipeline the pipeline weldering is made Shape is that floor space is big to reach the alleviation pipeline owing to being subjected to thermogenetic prolonged expansion, its shortcoming, and compensation rate is little, and fluid resistance is big, and thermal loss is big, and pipeline is long, and fixed support is many, investment and operating cost height; The ordinary cartridge compensator adopts the asbestos packing sealing, uses the flange connecting pipe, decentraction during as piping erection, will bring difficulty is installed, flange connects increases leakage point, and the asbestos packing sealing effect is poor, working life is short, very easily leaks, and must stop production and could keep in repair in case leak; Bellows is the circular rugosity of stainless steel book metallic, be connected on the pipeline to reach compensating action with flange, burst is easily split leakage, maintenance difficult, must stop production during maintenance, the corrugated expansion joint burst cracking during the Spring Festival in 1998 in Shenyang City's heat supply pipeline causes and stopped heat four days, bring very burden to common people's life, caused very big loss and negative effect for economic benefit and social benefit.

Summary of the invention

Deficiencies such as big in order to overcome existing compensator floor space, service time is short, and easily leakage, maintenance need to stop production, fluid resistance is big, and thermal loss is big, and investment and operating cost are big.The utility model provides a kind of filling type compensator, and not only floor space is little for it, good sealing effect, anticorrosion, do not leak, if any seepage, can get rid of in that pipeline is in service, directly weld without flange and pipeline, duct length is short, thermal loss and fluid resistance are little, and compensation rate is big, save steel and operating cost, little investment, cost is low.

The technological scheme that its technical problem that solves the utility model adopts is: it is assembled into filling type ball compensator, filling type sleeve expansion joint and filling type by bulb, frame, sphere bearing shell, seal ring, injecting mouth, injecting mouth sealing bolt, injecting mouth, sealing compound, back seat, convex core pipe, telescopic frame, guiding bearing shell, anticorrosion guiding bearing shell shell, boss, seat ring, seat ring seal ring, protecting jacket, spheroid etc. and buries sleeve expansion joint entirely.The filling type ball compensator, by bulb, spheroid, frame, injecting mouth sealing bolt, back seat, anticorrosion sphere bearing shell, seal ring, compositions such as sealing compound and injecting mouth, stud with anticorrosion sphere bearing shell and seal ring at the inboard two ends of frame, form a Seal cage with spheroid, inject sealing compound by the injecting mouth with pressure, after with injecting mouth sealing bolt the injecting mouth being tightened sealing, one end of pipe is welded on the back seat of this filling type ball compensator, the other end is welded on the bulb, form the double seal of seal ring and sealing compound thus to pipeline internal medium, simultaneously it watt bears the pulling force that pressure produced of pipeline internal medium again together with ball, pipeline is owing to the elasticity that temperature variation produced acts on bulb or the frame during work, bulb and frame are produced relative rotation, the thermal compensation to pipeline is finished in the mutual warpage motion of mending by a pair of ball, the thermal stress of extraction duct, and bulb can rotate arbitrarily in the space; The filling type sleeve expansion joint, by convex core pipe, telescopic frame, the guiding bearing shell, anticorrosion guiding bearing shell shell, seal ring, the injecting mouth, sealing compound, injecting mouth sealing bolt, boss, compositions such as back seat, seal ring is housed in the outside of convex core pipe guiding bearing shell and anticorrosion guiding bearing shell shell are housed at the two ends of this ring, at its outside installation sleeve cartridge type frame, form a Seal cage, inject sealing compound by the injecting mouth with pressure, after with injecting mouth sealing bolt the injecting mouth being tightened sealing, one end of pipe is welded on this filling type sleeve expansion joint back seat, the other end is welded on the convex core pipe, one end of convex core pipe is provided with boss, the infinite string that limits this pipe is moving, relies on the slide relative between convex core pipe and telescopic shell to compensate expanding with heat and contract with cold of pipeline during work; Filling type buries sleeve expansion joint entirely and the filling type sleeve expansion joint is basic identical, just adds seat ring one on an end of convex core pipe, and this seat ring is spill, adds the seat ring seal ring one at its recess place, prevents that outside all backward, corrupt and reactionary things from corroding compensator.

The beneficial effects of the utility model are: good sealing effect, do not leak, and need not stop production during seepage and can remove by maintenance platoon, floor space is few, saves steel and man-hour, and thermal loss and resistance are little, whole little investment, with low cost, operating cost is low.
