Abstract

The utility model belongs to accessories of pipe for transporting non-corrosive fluid essentially being used for compensating the axial extension and contraction and the radial rotating of pipes. The utility model includes a body which comprises an inner tube and an outer tube, and the structure is characterized in that the boss of the inner tube is provided with a YX type sealing ring of which the two sides are provided with an O type sealing ring respectively, and one terminal of the outer tube is provided with a felt sealing flange disc. The utility model has the advantages of safe and reliable working property, and is capable of reducing construction rate and the like.

Description

The directly buried type slip joint
The utility model is to belong to the annex of carrying no corrupt liquid pipeline, is mainly used in the axial stretching of compensation pipeline and rotation radially.
Because the difference variation of working medium and installation error factors cause flexible the reaching of pipeline axial radially to reverse; Radially reverse for eliminating flexible the reaching of pipeline axial, the material filling type sleeve expansion joint is installed in pipeline usually.But this compensator adopts the graphite packing sealing, in the pipeline telescopic process, easily causes graphite to leak, and makes the dielectric leakage in the pipeline, just needs additional fillers at any time.In under ground piping, must be provided with special maintenance well, therefore, improve engineering cost, and made troubles to maintenance work.
It is safe and reliable that the purpose of this utility model just provides a kind of service behaviour, the directly buried type slip joint of long service life.
The purpose of this utility model is achieved in that the utility model comprises body, body is made up of inner sleeve, outer sleeve, its structure outline is that the both sides that the boss of inner sleeve is provided with YX RunddichtringO, YX RunddichtringO are respectively arranged with the O RunddichtringO, and a termination of outer sleeve is provided with the flange plate with felt pan sealing.
Major advantage of the present utility model:
1, service behaviour is safe and reliable:
Because inner sleeve boss of the present utility model is provided with the both sides of YX RunddichtringO, YX RunddichtringO and is respectively arranged with the O RunddichtringO, under the situation of just having guaranteed not damage for many years, to the sealing of the medium in the pipeline; And the flange plate with felt pan sealing is set on a termination of outer sleeve, strengthened the intensity of outer sleeve greatly; Therefore, the utility model not only service behaviour is safe and reliable, and has improved working life;
2, reduced construction amount:
Because it is of the present utility model reasonable in design, service behaviour is safe and reliable, and improve working life (its life-span can reach 20 years), therefore, just removed the special maintenance well that is provided with from, can reduce engineering cost greatly, be used for the conveyance conduit of industries such as cities and towns heating, metallurgy, generating, petrochemical industry, building more easily.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that two ends of the present utility model are not provided with flange.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises body 2, body 2 is made up of inner sleeve 9, outer sleeve 6, the both sides that the boss 5 of inner sleeve 9 is provided with YX RunddichtringO 4, YX RunddichtringO 4 are respectively arranged with O RunddichtringO 3, and a termination of outer sleeve 6 is provided with the flange plate 8 with felt pan sealing 7.
During use, at first the flange plate 10 of the inner sleeve 9 of flange-type directly buried type slip joint, the flange plate 1 of outer sleeve 6 are connected with the piping flange dish respectively, or the outer end 11 of the outer end 12 of inner sleeve 9 that can't blue formula directly buried type slip joint, outer sleeve 6 is directly welded mutually with pipeline and is got final product.Self pressure action of flowing medium is on YX RunddichtringO 4, O RunddichtringO 3 in the pipeline, and YX RunddichtringO 4, O RunddichtringO 3 produce corresponding deformation, and the gap between inner sleeve 9, the outer sleeve 6 is sealed.
