Abstract
The utility model discloses a sealing structure of a high pressure oil pipe. The sealing structure comprises a high pressure oil pipe joint and a joint, and the sealing structure is characterized in the top end of the high pressure oil pipe joint is an arched surface, a union nut is sleeved at the outside of the high pressure oil pipe joint, threads matched with the union nut are arranged on the outer ring of the joint, an opening is arranged in the joint, the dimension of the opening is large at outside and small at inside and the opening is in a conical surface structure, the union nut is screwed on the threads on the outer ring of the joint, and the arched surface top end of the high pressure oil pipe joint is inserted in the opening of the conical surface structure of the joint. The sealing structure disclosed by the utility model has the advantages of simple structure and good sealing effect.
Description
Technical field
The utility model relates generally to the manufacturing field of high-pressure oil pipe, relates in particular to a kind of sealing configuration of high-pressure oil pipe.
Background technique
Traditional sealing configuration is the sealing of the conical surface to the conical surface, when the conical surface and conical surface seal, because the difference of mounting position degree causes the inefficacy that seals easily.And the sealing of the sphere and the conical surface can be tolerated a certain amount of installation deviation, thereby guarantees sealing.For 1600 atmospheric structures that are tightly connected of ultrahigh pressure, this structure is verified very effective.
The model utility content
The utility model purpose is exactly in order to remedy the defective of prior art, the sealing configuration of the high-pressure oil pipe of a kind of sphere and the conical surface to be provided.
The utility model is realized through following technological scheme:
The sealing configuration of high-pressure oil pipe; Include high-pressure oil pipe joint, joint, it is characterized in that: the top of said high-pressure oil pipe joint is an arc shaped surface, the outer union nut of suit of said high-pressure oil pipe joint; Include the screw thread supporting on the outer ring of said joint with union nut; Include an opening in the said joint, said opening is of a size of in outer big little, is cone structure; Said union nut is tightened on the screw thread of joint outer ring, in the opening of the cone structure of the arc shaped surface top insertion joint of said high-pressure oil pipe joint.
The sealing configuration of described a kind of high-pressure oil pipe is characterized in that: the arc shaped surface of said high-pressure oil pipe joint contacts with the conical surface of joint.
The utility model has the advantages that: simple in structure, good sealing effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the sealing configuration of high-pressure oil pipe includes high-pressure oil pipe joint 1, joint 3; The top of said high-pressure oil pipe joint 1 is an arc shaped surface; Union nut 2 of said high-pressure oil pipe joint 1 outer suit includes the screw thread supporting with union nut on the outer ring of said joint 3, include an opening in the said joint 3; Said opening is of a size of in outer big little; Be cone structure, said union nut 2 is tightened on the screw thread of joint 3 outer rings, in the opening of the cone structure of the arc shaped surface top insertion joint 3 of said high-pressure oil pipe joint 1.
The arc shaped surface of said high-pressure oil pipe joint 1 contacts with the conical surface of joint 3.
Claims (2)
