Abstract
The utility model relates to the technique of machining working, which is an expansion joint for adjusting the linear variation of conduit axial direction and the angular variation of the delivery conduit which are caused by the change of temperature and length. The utility model adopts sleeve-type twofold self-seal structure, and an oil sump is added between two seal rings; one of the two seal rings is an O-shaped seal ring, and the other is Y<x>-shaped seal ring; the sleeve type is that the left side is an external joint sleeve, and the right side is an internal joint sleeve; the external and the internal sleeves of the expansion joint can slide freely in a sliding sleeve 4, and is flexible; the second seal ring uses proof high-pressure rubbery material.
Description
The utility model relates to machining aspect technology, and concrete what is said or talked about is the slip joint that a kind of pipeline axial linear change that is used to regulate conveyance conduit Yin Wendu and length change and causes and radial angle change.
Graphite packing is adopted in the sealing of old-fashioned slip joint, after the length of pipeline changes, after the sealing surface distortion through adjusting asbestos packing several times, be difficult for resiling, sealing effect descends gradually, therefore, old-fashioned slip joint easily leaks, leaks vapour, needs often maintenance, changes filler.
The purpose of this utility model designs a kind of good sealing effect, works together nimbly and freely, the slip joint of long product lifecycle.
The technical solution of the utility model is:
This product specification is adopted telescopic dual from movable sealing structure, adds an oil storage tank between the two seals circle, and one on described two seals circle is the O RunddichtringO, and another is the Yx RunddichtringO; The described telescopic left side that is meant is the acromere cover, and the right side is the internal segment cover; Can be free to slide in sliding sleeve between the overcoat in the slip joint, nimbly and freely, described seal ring adopts high pressure resistant rubber material.
Good effect of the present utility model is:
This slip joint, the sealing surface that has fundamentally overcome old-fashioned slip joint is difficult for the shortcoming of adjustment, make this product have sealing reliably, flexibly, in time eliminate the Installation Stress of pipeline, move freely, compensation range is big, and maintenance period is long, characteristics such as life of product is long are that slurry transportation pipeline is used for the optimal product that compensating length changes.
Fig. 1 is the utility model structural representation.
Describe the utility model structure in detail below in conjunction with accompanying drawing embodiment:
Compositions such as 1 acromere cover, 2 " O " RunddichtringO, 3 " Yx " RunddichtringO, 4 sliding sleeves, 5 internal segment covers, this product adopts telescopic dual from movable sealing structure, first road sealing " O " RunddichtringO of rubber, second road sealing " Yx " RunddichtringO of polyurethane, polyurethane is a kind of novel high pressure resistant rubber, and " Yx " RunddichtringO lip limit when pressurized can be opened automatically, guarantees the sealing between the overcoat in the slip joint, pressurized is high more, and sealing effect is good more.We also add an oil storage tank between this two seals circle, nimbly and freely, this sealing configuration can still can keep good sealing state to the assurance slip joint after thousands of adjustment, and can make slip joint not change seal ring and maintenance within 4 years when work.
Claims (2)
1, a kind of slip joint that is used to regulate conveyance conduit, described product are a kind of telescopic dual from the motive sealing slip joint, and it is telescopic dual from movable sealing structure to it is characterized in that this device adopts, and adds an oil storage tank between the two seals circle; One on described two seals circle is 0 RunddichtringO 2, and another is a Yx RunddichtringO 3; The described telescopic left side that is meant is acromere cover 1, and the right side is the internal segment cover; Can in sliding sleeve 4, be free to slide between the overcoat in the slip joint, nimbly and freely.
2,, it is characterized in that the described second road seal ring adopts high pressure resistant rubber material according to the described a kind of slip joint of claim 1.
