Abstract
The utility model discloses a hydraulic sleeve compensator of a high-pressure pipeline. The hydraulic sleeve compensator comprises an outer pipe and an inner pipe. One end of the outer pipe sleeves the outer wall of one end of the inner pipe. The outer pipe is in sliding connection with the inner pipe. A cylinder sleeve sleeves the outer wall of the inner pipe. Inner diameter of the cylinder sleeve is larger than outer diameter of the outer pipe. One end opposite to the outer pipe of the cylinder sleeve is in sealing connection with the outer wall of the inner pipe, and gap between the other end facing the outer pipe of the cylinder sleeve and the outer wall of the inner pipe is opened. Chambers with one ends opened and the other ends sealed are respectively formed between the inner wall of the cylinder sleeve and the outer wall of the inner pipe. Ends of the outer pipe which is inserted in the chambers through chamber openings are respectively connected with pistons. The pistons are matched with the chambers respectively. The outer wall of the outer pipe is in sealing connection with the inner wall of the cylinder sleeve on the chamber openings through sealing parts. Two ends of each chamber are respectively communicated with a hydraulic station through an oil hole A and an oil hole B which are formed in the wall of the cylinder sleeve. Medium pressure in the pipeline acts on hydraulic oil in the chambers, thus acting force on a pipeline frame is reduced, pipeline safety is improved, and build cost of the high-pressure pipeline is lowered.
Description
Technical field
The utility model relates to compensator field, is specifically related to a kind of hydraulic-pressure sleeve compensator of pressure duct.
Background technique
Compensator is a kind of for compensating the additional stress causing because of temperature difference and mechanical vibration, and is arranged on a kind of flexible structure on container shell and pipeline.Compensator for pipeline mainly comprises bend pipe compensator, corrugated expansion joint and sleeve expansion joint at present, the tube wall of corrugated expansion joint is thin wall multi-layer structure, flexible large, be applicable to temperature and pressure all not bery high, and the shorter pipeline of length, be subject to the impact of metal fatigue degree, its flexible number of times is restricted, and working life is shorter; Bend pipe compensator intensity is good, and the life-span is high, can field fabrication, but it takes up room large shortcoming to erecting bed require highly, and large to the surface friction drag of pipeline medium, it uses restriction more; The compact structure of sleeve expansion joint, surface friction drag to medium is also very little, but ducted pressure acts directly on the fixed support of pipeline, especially high pressure pipe line, easily cause fixed support distortion, affect the Security of pipeline, therefore current high pressure pipe line generally still adopts bend pipe compensator, the spatial construction expense of erecting bed is high, and the construction cost of high pressure pipe line integral body is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of hydraulic-pressure sleeve compensator of pressure duct, the pipeline internal medium pressure that can solve current use sleeve expansion joint directly acts on fixed support, affect the Security of pipeline, cause high pressure pipe line generally to adopt bend pipe compensator, the problem that construction cost is high.
The utility model is achieved through the following technical solutions:
A kind of hydraulic-pressure sleeve compensator of pressure duct, comprise outer tube and inner tube, described outer tube one end is enclosed within the outer wall of inner tube one end, the two is slidably connected, described outer wall of inner tube is also provided with cylinder sleeve, the internal diameter of described cylinder sleeve is greater than the external diameter of outer tube, one end and the outer wall of inner tube of outer tube are tightly connected dorsad for they, between its other end towards outer tube and outer wall of inner tube, it is open state, between inboard wall of cylinder liner and outer wall of inner tube, form the cavity of an end opening, one end sealing, described outer tube inserts inside cavity from opening, and its end is also connected with the piston matching with cavity; The outer wall of described outer tube is tightly connected by the inboard wall of cylinder liner at Sealing and cavity hatch place, and described cavity two ends are communicated with hydraulic station by A oilhole and the B oilhole being arranged on cylinder bore wall respectively.
The relative outer end of described outer tube and inner tube is also respectively equipped with flange.
The utility model advantage is compared with prior art:
One, by cylinder sleeve and outer wall of inner tube, form cavity, the piston that tube end setting outside matches with cavity, and cavity two ends by being arranged at A oilhole on cylinder bore wall and B oilhole, be communicated with hydraulic station respectively, by pipeline internal medium pressure then act on the hydraulic oil in cavity, thereby reduce the active force to support of pipelines, the Security that improves pipeline, makes sleeve expansion joint also can be used for high pressure pipe line, reduces the construction cost of high pressure pipe line;
Two, between outer tube and inner tube, can rotate, can reduce the moment of torsion of high pressure pipe line, further strengthen the Security of high pressure pipe line.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
