Abstract
The invention provides a self-operated sealing sleeve compensator. A drag reducing sleeve is arranged at the connecting position of a sleeve, the drag reducing sleeve is made of flexible materials, a leakage-resistant sealing rubber gasket is arranged at the telescopic part of the compensator, and the two ends of the leakage-resistant sealing rubber gasket are a concave surface and a convex surface respectively. When the self-operated sealing sleeve compensator is used and needs to stretch out and draw back, the leakage-resistant sealing rubber gasket is used for sealing the telescopic part of the compensator, and the pressure of a sealing surface is from fluid pressure in a pressure balancing hole. When the pressure is appropriate, the pressure of the concave surface of the leakage-resistant sealing rubber gasket can increase along with increase of the internal fluid pressure to enable the leakage-resistant sealing rubber gasket to flow outwards, and the convex surface is made to be attached to the inner wall of an outer sleeve so as to prevent a fluid from flowing out. The technical problem of economic losses caused by the fact that the fluid leaks from the inside due to the fact that packing seal is untight after an inner sleeve and the outer sleeve move relatively because sealing materials of an original sleeve type compensator is compact and undergoes hard extrusion and repeated multi-time system heat and cold changes is solved.
Description
Technical field
Patent of the present invention is applicable to the thermal compensation of pipeline in fluid is carried, and according to International Patent Classification (IPC) (IPC), divides and belongs to human life need part, is applicable to the technical fields such as heat supply, cooling, oil, chemical industry.
Background technique
Pipe-type compensator also claims material filling type compensator, is widely used in heat distribution pipeline in recent years.Particularly in some special places, other compensators cannot be installed, all adopt sleeve compensator.But often send out into the phenomenon that compensator leaks, mainly because the sealing material of original pipe-type compensator is compression type, the rigid extruding of sealing material, the cold and hot variation of system through repeated multiple times, causes packing seal sternly not cause fluid to cause economic loss from internal leakage after internal and external casing relatively moves.
Summary of the invention
The object of the present invention is to provide a kind of self-powering type Sealed casing pipe compensator.The sealing material that solves original pipe-type compensator of take is compression type, the rigid extruding of sealing material, and the cold and hot variation of system through repeated multiple times, causes packing seal sternly not cause fluid from the technical problem of internal leakage after internal and external casing relatively moves.The technological scheme that the above-mentioned technical problem that the present invention will solve adopts is achieved in that and adopts flexible material (as: rubber), the flexible position of compensator is sealed, and sealing surface and pressure from the internal fluid pressure of equalizing orifice.During moderate pressure, can increase with internal fluid pressure, put on the concave panel of Drain Resistance O-ring seal, Drain Resistance O-ring seal outwards be flowed, and then the convex panel of Drain Resistance O-ring seal is adjacent to outer sleeve inner wall, prevent that fluid from flowing out.With regard to having solved the sealing material of original pipe-type compensator, be compression type like this, the rigid extruding of sealing material, the cold and hot variation of system through repeated multiple times, causes packing seal sternly not cause fluid from internal leakage, to cause the technical problem of economic loss after internal and external casing relatively moves.
Accompanying drawing explanation
Fig. 1 is self-powering type Sealed casing pipe compensator structure schematic diagram of the present invention.
Fig. 2 is the partial schematic diagram of Fig. 1.
In figure: 1 outer sleeve, 2 inner sleeves 3, drag-reduction casing 4, Drain Resistance O-ring seal 5, pressure compensation opening 6, Drain Resistance O-ring seal concave panel, 7 Drain Resistance O-ring seal convex panels, 8 stiffening ring ribs.
Embodiment
Below in conjunction with accompanying drawing, the sealing material that self-powering type Sealed casing pipe compensator of the present invention is solved to original pipe-type compensator for realizing is compression type, the rigid extruding of sealing material, through the repeated multiple times cold and hot variation of system, the technological scheme that causes packing seal sternly not cause fluid to cause the technical problem of economic loss to take from internal leakage after internal and external casing relatively moves is described further:
Its static structure: please refer to accompanying drawing, as shown in the figure, at sleeve pipe joining place, drag-reduction casing is set, in drag-reduction casing, adopt flexible material (as: rubber), the flexible position of compensator is arranged to Drain Resistance O-ring seal to be sealed, Drain Resistance O-ring seal two ends are respectively concave panel and convex panel, the matrix design of Drain Resistance cushion rubber is in order to prevent that internal flow from flowing out from stiffening ring rib and Drain Resistance cushion rubber surface of contact, wear resistance to Drain Resistance cushion rubber when convex panel relatively moves between inner sleeve and outer sleeve in order to strengthen, thereby increase working life, reduce maintenance frequency, reduce amount of maintenance.
Below by using method, further set forth the dynamic structure relation of self-powering type Sealed casing pipe compensator of the present invention: when self-powering type Sealed casing pipe compensator comes into operation, in the time of need to stretching, Drain Resistance O-ring seal seals the flexible position of compensator, sealing surface and pressure carry out the internal fluid pressure of pressure compensation opening.When moderate pressure, the pressure of the concave panel of Drain Resistance O-ring seal can increase with internal fluid pressure, Drain Resistance O-ring seal is outwards flowed, and then the convex panel of Drain Resistance O-ring seal is adjacent to outer sleeve inner wall, prevents that fluid from flowing out.By the concave panel of Drain Resistance O-ring seal, pressure compensation opening Drain Resistance O-ring seal, convex panel and stiffening ring rib Combination Design, liquid imports by pressure compensation opening, make internal flow produce thrust to the concave panel of Drain Resistance O-ring seal and leakage O-ring seal, thereby Drain Resistance O-ring seal is fitted tightly at the convex panel of Drain Resistance O-ring seal and the inwall of outer sleeve, prevent liquid leakage, realized fluid to automatically the providing of sealing force, further made the power of sealing reach the object that is not only unlikely to excessive but also reaches sealing effect.By inner sleeve and drag-reduction casing combination, reduced fluid mobile local resistance in pipe, be conducive to improve the water conservancy stability of pipe network, reduce operation energy consumption, make original sleeve compensator sealing improved, initial cost cost, operating maintenance maintenance cost has reduced, the sealing material that solves so original pipe-type compensator with regard to having realized is compression type, the rigid extruding of sealing material, through the repeated multiple times cold and hot variation of system, after relatively moving, internal and external casing cause packing seal sternly not cause fluid from internal leakage, to cause the object of the technical problem of economic loss.
