Abstract
The utility model relates to an elastic non-pushing force pipe auto-compensator; because an elasticity set arranged in the cavity formed between an elastic pipe and an outer sheath is connected with one end face of the outer sheath through a pressure regulating plate and a pressure regulating screw bolt; a guiding sealing ring set is arranged on the top of an expansion pipe; slaking blind holes are uniformly distributed on the elastic pipe which approaches to the guiding sealing ring set. The compensator has reasonable structure, good sealing effect and convenient maintenance and can effectively eliminate the pushing of the medium, the stability and the reliability of the pipeline can be assured, and the utility model is in the favorable sealing state.
Description
The utility model relates to a kind of compensation of pipeline device, particularly elasticity does not have thrust pipeline automatic compensator.
At present, the compensation of pipeline device kind that adopts in the pipework of fed sheet of a media is a lot.And a kind of " elastic piston formula pipeline compensator " once disclosed on the Chinese patent communique, its notification number is: CN2101161, the patent No. is: 91219236.4.This compensator comprises the piston ring group that is made of metallic piston ring and rubber piston ring between telescopic pipe and piston sleeve, be positioned at piston ring group one end and be installed in retaining ring on the telescopic pipe, be positioned at the elasticity group of the piston ring group the other end, this elasticity group places in the oil sump in the space that constitutes between the outer sleeve that is connected with piston sleeve and the telescopic pipe.Compensation rate is big though this kind compensator has, the characteristics of good sealing effect, and it is difficult to eliminate bigger medium thrust, be difficult to guarantee fed sheet of a media pipeline stability preferably, and maintenance is inconvenient.
The purpose of this utility model is to provide a kind of elasticity not have thrust pipeline automatic compensator, and it is not only easy to maintenance, and can eliminate medium thrust effectively, makes the fed sheet of a media pipeline stabilization reliable, and keeps good sealing state.
Its solution is: outer sleeve is housed on the telescopic pipe, and it is connected by oversheath and sheathed casing and constitutes, and on the sheathed casing overflow hole is arranged.The elasticity group that is provided with in the cavity that forms between telescopic pipe and oversheath is connected with the connecting ring of regulator bolts with oversheath one end by regulator board, can adjust the pressure of elasticity group easily.Be provided with in the cavity that between telescopic pipe and sheathed casing, forms with the contacted seal ring group of elasticity group, and pilot seal ring group is arranged on the top of telescopic pipe, make between seal ring group and pilot seal ring group to form a balance chamber, be evenly equipped with the blind hole that disappears with the balance chamber corresponding position on the telescopic pipe.Blind hole has 6 at least but this disappears.When in the pipeline during fed sheet of a media, part medium flows in the balance chamber from the blind hole that disappears, pilot seal ring group one end face is produced a pressure medium, and the medium thrust that bear this pressure and pilot seal ring group other end balances each other, thereby can eliminate the end thrust of medium pipeline.
Because the elasticity group that is provided with in the cavity that the utility model forms between telescopic pipe and oversheath is connected on oversheath one end face by regulator board, regulator bolts, and be provided with pilot seal ring group on the top of telescopic pipe, in being evenly equipped with the blind hole that disappears near on the telescopic pipe at pilot seal ring group place.So it is not only rational in infrastructure, good sealing effect, easy to maintenance, and can eliminate the thrust of medium to pipeline effectively, thereby can make pipeline stabilization reliable, and keep good sealing state.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the plan view of elasticity unit thrust pipeline automatic compensator.
Fig. 2 is A-A sectional view.
Among Fig. 1, Fig. 2, telescopic pipe is set with outer sleeve on (1), and this outer sleeve is welded by same sheathed casing (12) one ends of connecting ring (8) with the welding of one end by oversheath (4) and constitutes.The other end of oversheath (4) connects sealing by sealing cover (2) by screw (3), and connecting ring (14) same fixed tube (15) welding of the other end of sheathed casing (12) through being welded as a whole with it, and sheathed casing (12) is provided with the overflow hole (16) of getting rid of waste liquid (or waste gas).In the cavity that forms between telescopic pipe (1) and oversheath (4) the elasticity group is installed, it is connected with the connecting ring (8) of oversheath (4) one end faces by regulator bolts (9).But this elasticity group is by the regulator board (5), the relief frame (7) that are sleeved on successively on the telescopic pipe (1), and 6 propelling springs (6) and the regulator bolts (9) that are distributed on them between the two constitute.Be equipped with and the contacted seal ring group of elasticity group in the cavity that between telescopic pipe (1) and sheathed casing (12), forms, it is by packing press ring (10) and the alternate layout of stuffing box packing (11) made with rubber and plastic or asbestos packing and constitute, and be installed in the top of telescopic pipe (1) by the pilot seal ring group (13) that stuffing box packing and pressure ring are formed, form a balance chamber (18) between seal ring group and pilot seal ring group (13), telescopic pipe (1) is gone up and the corresponding position of balance chamber (18) is evenly equipped with 6 blind holes that disappear (17).
When medium passes through conveyance conduit, the seal ring group that is arranged on the telescopic pipe (1) is in good sealing state under the effect of elasticity group pressure and this a pair of equilibrant of pressure medium, to prevent the dielectric leakage in the pipeline, and because the effect of elasticity group can also compensate the axial displacement that produces because of pipeline heat expansion, shrinkage automatically.Simultaneously, be arranged on pilot seal ring group (13) both ends of the surface on telescopic pipe (1) top, be subjected to from the pressure of telescopic pipe (1) outlet port medium and from the effect that flows into the pressure medium in the balance chamber in the blind hole that disappears (17), these two kinds of pressure form a pair of equilibrant, thereby can eliminate the end thrust that medium produces pipeline, reliable to guarantee pipeline stabilization.
Claims (2)
1, a kind of elasticity does not have thrust pipeline automatic compensator, comprise telescopic pipe, the elasticity group, it is characterized in that being set with on the telescopic pipe (1) by oversheath (4) and be connected with sheathed casing (12) and the outer sleeve that constitutes, overflow hole (16) is arranged on the sheathed casing (12), the elasticity group of setting is connected with the connecting ring (8) that an end of oversheath (4) is connected by regulator board (5) and regulator bolts (9) in the cavity that forms between telescopic pipe (1) and oversheath (4), be provided with the contacted seal ring group of elasticity group in the cavity that between telescopic pipe (1) and sheathed casing (12), forms, pilot seal ring group (13) is arranged on the top of telescopic pipe (1), make to form a balance chamber (18) between seal ring group and pilot seal ring group (13), telescopic pipe (1) is gone up and balance chamber (18) opposite position place is evenly equipped with the blind hole that disappears (17).
2, elasticity as claimed in claim 1 does not have thrust pipeline automatic compensator, and the blind hole that disappears (17) that it is characterized in that being distributed on the telescopic pipe (1) has 6 at least.
