Abstract
The invention aims to provide a high-temperature and high-pressure sleeve type compensator. Sliding bearings with a self-lubricating characteristic are used as compression rings on two sides of sealing packing of the compensator, an outer sleeve, an inner sleeve and the sliding bearings with the self-lubricating characteristic are assembled to form a sealing material packing cavity of the high-temperature and high-pressure sleeve type compensator, and the sliding bearings which are used as the compression rings are arranged on two sides of the sealing material packing cavity. By the aid of the sliding bearings with the self-lubricating characteristic, namely the compression rings, concentricity of the outer sleeve and the inner sleeve can be maintained, resistance of the inner sleeve and the outer sleeve of the compensator to tangential torque which destroys sealing capacity of the sealing packing can be strengthened, the sliding bearings are also the compression rings on the two sides of the sealing material packing cavity, accordingly, the sealing material packing cavity is provided with a sliding bearing compression ring supporting structure, gaps among the sliding bearings, namely the compression rings, and the inner sleeve and the outer sleeve of the compensator are small, contact area of working liquid media of the compensator and the sealing packing is reduced, requirements on performances of the sealing packing of the compensator under high-temperature and high-pressure conditions are lowered, the structure of the compensator is simplified, and a sealing performance of the sealing packing is improved.
Description
Technical field
The present invention relates to a kind of HTHP slip-type expansion joint, belong to the technical field of piping element.
Background technique
The HTHP slip-type expansion joint is the pith in the HTHP pipe network.The slip-type expansion joint seal leakage is the major reason that causes the compensator burn into damaged.The leakage of pipeline compensator, break, defective such as frictional force is excessive all can bring either large or small operation undesired even cause major break down to pipe network system.Through the sleeve expansion joint analysis to losing efficacy, pipeline makes the stuffing box packing of this gap receive radially asymmetric extruding because a variety of causes off-design position causes the sleeve expansion joint internal and external casing to receive the lateral torsion effect, and sealing is damaged.Slip-type expansion joint sealing material packing cavity is made up of the pressure ring or the boss cooperation of slip-type expansion joint outer sleeve, inner sleeve and packing cavity both sides in addition; But the pressure ring of packing cavity both sides or boss and interior or the housing part matching gap is bigger; Cause the stuffing box packing chamber that bigger space is arranged, be damaged at the HTHP lower seal.
Summary of the invention
The objective of the invention is to propose a kind of usefulness and have the pressure ring of the sliding bearing of self-lubricating property as both sides, HTHP slip-type expansion joint stuffing box packing chamber, HTHP slip-type expansion joint sealing material packing cavity is made up of the sliding bearing pressure ring cooperation with self-lubricating property of outer sleeve internal surface, inner sleeve outer surface and packing cavity both sides.Sliding bearing pressure ring with self-lubricating property promptly keeps the concentricity between outer sleeve and the inner sleeve; Can strengthen the ability that compensator internal and external casing opposing tangential moment of torsion destroys the stuffing box packing sealing; Be again the pressure ring that sealing material packing cavity two is surveyed, the sealing material packing cavity of this band sliding bearing pressure ring supporting structure, sliding bearing pressure ring and compensator inner sleeve surface gap are very little; Reduced the area of contact of compensator liquid working medium and stuffing box packing; The performance requirement that reduces to have reduced compensator stuffing box packing under high-temperature and high-pressure conditions of stuffing box packing compression area has been simplified compensator structure, has improved the sealability of stuffing box packing.
Its structural representation of HTHP slip-type expansion joint that the present invention proposes is as shown in Figure 1.
The technological scheme that the present invention adopts is:
A kind of HTHP slip-type expansion joint is made up of outer sleeve 1, outer casing pressure pipe 2, inner sleeve 3, hold-down bolt 4, the sliding bearing pressure ring 5 with self-lubricating property, stuffing box packing 6.Outer sleeve 1 internal diameter is a cascade, has 3 ladders, from left to right; Increase successively; The outer surface of inner sleeve 3 intermediate sections is provided with a ring-like outer bulge loop as the anticreep shackle, and two sliding bearing pressure rings 5 with self-lubricating property are sleeved on the outer surface in inner sleeve 3 ring-like outer bulge loop left sides, and insert the right-hand member of outer sleeve 1; The sliding bearing pressure ring with self-lubricating property 5 in left side offsets with the middle ladder right-hand member of outer sleeve 1 internal diameter; Outer casing pressure pipe 2 is sleeved on the inner sleeve 3 from inner sleeve 3 right sides, and inserts the right-hand member of outer sleeve 1, offsets with the sliding bearing pressure ring 5 with self-lubricating property on right side.It is characterized in that: constitute the stuffing box packing chamber between two sliding bearing pressure ring 5, outer sleeve internal surface and inner sleeve outer surfaces with self-lubricating property; Stuffing box packing 6 is positioned at Seal cage; Outer casing pressure pipe 2 is fixed through hold-down bolt 4 and outer sleeve, and through the sliding bearing pressure ring 5 with self-lubricating property stuffing box packing 6 is compressed.Two sliding bearing pressure rings 5 with self-lubricating property guarantee that simultaneously outer sleeve 1 and inner sleeve 3 are coaxial.
Outer casing pressure pipe 2 internal surface low order ends are provided with an outer bulge loop, and outer bulge loop internal diameter is less than the outer bulge loop external diameter of inner sleeve 3 outer surfaces, and the outer bulge loop of inner sleeve 3 outer surfaces is positioned at the outer bulge loop of outer casing pressure pipe 2 internal surfaces left side.
Described HTHP slip-type expansion joint, its structure also can be used for the slip-type expansion joint under the common high temperature and high pressure environment.
