Abstract
The utility model relates to a wellhead hardware device of a wellhead oil-extraction tree, particularly to a high-pressure compound sealer. The utility model provides a technical scheme as follows: the high-pressure compound sealer includes a steel ring, an O-shaped ring and a hoop, and is characterized in that a mounting groove is arranged on the outer wall of the steel ring, the O-shaped ring is mounted in the mounting groove of the steel ring, the steel ring is placed in the hoop, the hoop has a soft sealing groove, and the outer skin of the hoop is tightly screwed on the hoop. The utility model has effects as follows: the sealing surface of the original steel ring is retained, a second auxiliary soft sealing is formed between the plane and the sealing surface of the hoop on the premise that the original sealing is not damaged, the installation is convenient, the soft sealing body is directly installed in the mounting groove of the steel ring and forms sealing with the hoop, the light leakage surface formed by the hard sealing between the steel ring and the hoop can be efficiently blocked by the soft sealing after the installation, the steel ring can be replaced through the soft sealing, and the purpose of repeated uses can be achieved.
Description
One, technical field:
The utility model relates to the wellhead hardware device of a kind of well head production tree, specifically is high pressure compound seal device.
Two, background technology:
At present, each oil field oil recovery gas production is the octagon steel ring with the primary structure form that the steel ring in the clip head adopts, because seal request, often need apply very big pressure, be easy to cause the clip head with steel ring crimp, when steel ring reuses, form building light face, produce seepage in sealing place.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of easy for installation, and thoroughly solving has well to connect with the poorly sealed high pressure compound seal device that causes the connecting portion leakage problems of steel ring.
Its technical scheme is: the utility model comprises steel ring, O type circle, clip, and it is characterized in that: the steel ring outer wall is provided with mounting groove, and O type circle is installed in the mounting groove of steel ring, and steel ring is inserted in the clip, and clip is provided with the soft seal groove, and the clip crust is tightened on the clip.
Effect of the present utility model is: the sealing surface that has kept former steel ring, do not destroy on the basis of original sealing, between plane and clip sealing surface, formed the auxiliary soft seal of secondary, easy for installation, the soft seal body is directly installed in the steel ring mounting groove, forms sealing, the back soft seal is installed the light leak face that hard sealing between steel ring and the clip forms has been formed effective shutoff with clip, steel ring is replaceable by soft seal, reaches nonexpondable purpose.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment:
With reference to accompanying drawing, the utility model comprises steel ring 2, O type circle 1, clip 5, it is characterized in that: steel ring 2 outer walls are provided with mounting groove 6, O type circle 1 is installed in the mounting groove 6 of steel ring 2, steel ring 2 is inserted in the clip 5, and clip 5 is provided with soft seal groove 3, and clip crust 4 is tightened on the clip 5.
During installation, at first O type circle 1 is installed in the mounting groove 6 of steel ring 2, then steel ring 2 is fit into clip 5 junctions, tightening clip crust 4 gets final product, steel ring 2 engages with soft seal groove 3, the sealing surface that back steel ring 2 and clip 5 are installed forms once sealing, firmly seal iron for iron this moment, very easily form the light leak face, liquid in the flow process can reach soft sealing face from the outside seepage of light leak, and seal is a compressible object, therefore effusion, oil are played good sealing function, administer the seepage purpose thereby reach.
