Abstract

The utility model relates to a high-pressure pipeline connecting structure. The high-pressure pipeline connecting structure is characterized by comprising an oil pipe I, wherein a flange I is welded on the orifice of the oil pipe I; the other end face of the flange I is connected with a flange II through a fastener; an oil pipe II is welded on the other end face of the flange II; the oil pipe I, the flange I, the flange II and the oil pipe II are the same in inner diameters, and are coaxial; a spring rubber sleeve is sleeved in the inner holes of the flange I and the flange II; radial circumferential flanges are arranged at the upper end and the lower end of the spring rubber sleeve; the circumferential flange at the upper end of the spring rubber sleeve is compressed at the joint between the oil pipe I and the flange I; the circumferential flange at the lower end of the spring rubber sleeve is compressed at the joint between the oil pipe II and the flange II. The high-pressure pipeline connecting structure has the advantages of simple structure and good sealing effect, and leakage of a pipeline connecting joint can be avoided completely.

Description

A kind of pressure duct linkage structure
Technical field
The utility model belongs to pipe connection structure technical field, particularly relates to a kind of pressure duct linkage structure.
Background technique
Flange arrangement in existing high-pressure liquid pipeline system, adopts planar radial to be tightly connected mostly.In the high-volume hydraulic pipe-line system of stamp forging hydraulic press and so on, because system is in control procedure, in pipeline, can produce very large hydraulic shock, fastening piece for adpting flange can be elongated and deformed under repeatedly long-term impact force action, make two surface of contact between flange produce gap, thereby cause pressure duct joint to be leaked, when serious, can cause sealing original paper to damage, make hydraulic press occur seriously leaking, affect the usability of hydraulic press.
Summary of the invention
The pressure duct linkage structure that the utility model provides a kind of simple in structure, good sealing effect, can avoid pipeline connecting flange place to leak completely for the technical problem that solves the pipeline connecting flange place that exists in known technology and easily leak.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of pressure duct linkage structure, it is characterized in that: comprise oil pipe I, the mouth of pipe of oil pipe I is welded with flange I, the other end of flange I is connected with flange II by fastening piece, the other end of described flange II is welded with oil pipe II, the identical and coaxial line of the internal diameter of oil pipe I, flange I, flange II and oil pipe II; Pocketed springs rubber sleeve in the endoporus of described flange I and flange II, the top and bottom of described spring-rubber cover are provided with circumferential flange radially, the circumferential flange of described spring-rubber set upper side is pressed on the seam crossing of oil pipe I and flange I, and the circumferential flange of described spring-rubber cover lower end is pressed on the seam crossing of oil pipe II and flange II.
The utility model can also adopt following technological scheme:
Described fastening piece is screw.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technological scheme, in the endoporus of pipeline connecting flange, add spring-rubber cover, spring-rubber cover seals two joint places of two flanges completely, simple in structure, good sealing effect, can avoid the leakage of pipeline connecting flange completely.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, oil pipe I; 2, flange I; 3, fastening piece; 4, flange II; 5, oil pipe II; 6, spring-rubber cover.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of pressure duct linkage structure, comprise oil pipe I1, the mouth of pipe of oil pipe I1 is welded with flange I2, the other end of flange I1 is connected with flange II4 by fastening piece 3, the other end of described flange II4 is welded with oil pipe II5, the identical and coaxial line of the internal diameter of oil pipe I1, flange I2, flange II4 and oil pipe II5.Pocketed springs rubber sleeve 6 in the endoporus of described flange I2 and flange II4, the top and bottom of described spring-rubber cover 6 are provided with circumferential flange radially, the circumferential flange that described spring-rubber overlaps 6 upper ends is pressed on the seam crossing of oil pipe I1 and flange I2, and the circumferential flange that described spring-rubber overlaps 6 lower ends is pressed on the seam crossing of oil pipe II5 and flange II4.In the present embodiment, fastening piece 3 is screw.
After in pipeline, long-term impact force is elongated the screw of adpting flange I and flange II repeatedly, spring-rubber cover can prevent liquid in the pipeline joint leadkage from flange I and flange II completely.
Above-mentioned mode of execution is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model; as: the two ends of spring-rubber cover are bonded in respectively on flange I and flange II; the same effect of utilizing spring-rubber cover to stop pipeline leakage that realizes, within all dropping on protection domain of the present utility model.
