Abstract

The utility model discloses a flange mounting structure for a high-pressure pipe. The flange mounting structure comprises 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 sealing sleeve body is arranged on the flange I; the sealing sleeve body comprises an upper circular body connected with the flange I, a lower circular body sleeves the outer peripheral face of the flange II in parallel with the upper circular body, and a circumferential sleeve body connected with the upper circular body and the lower circular body; a circular sealing sponge is arranged on the inner side of the circumferential sleeve body; sealing rubber rings are arranged between the sealing sponge and the upper circular body as well as between the sealing sponge and the lower circular body. By adopting the sealing structure, the joint of pipe bodies can be sealed after a gap occurs between the two flanges due to vibration. The flange mounting structure is easy to disassemble, assemble and repair, a good sealing effect is achieved, and leakage at flange joints in pipelines can be completely avoided.

Description

A kind of flange installation structure of high-voltage tube
Technical field
The utility model belongs to pipe connection structure technical field, particularly relates to a kind of flange installation structure of high-voltage tube.
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 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, and is convenient to the flange installation structure of the high-voltage tube that dismounting safeguards.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of flange installation structure of high-voltage tube, 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; On described flange I, sealing body is installed, described sealing body comprises the upper cirque body that is connected with flange I, is contained in lower cirque body on flange II outer circumferential face, is connected cirque body and lower toric circumference body with upper cirque body parallel sleeve, the inner side of described circumference body is provided with the sealing sponge of ring, between described sealing sponge and described upper cirque body and sealing sponge and lower cirque body, is equipped with O-ring seal.
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 outside of pipeline connecting flange, add sealing body, the inner side of sealing body is also provided with sealing sponge and O-ring seal, this sealing configuration can guarantee after two flanges occur gap because of vibrations, the joint of body to be sealed, structure dismounting is easy to maintenance, good sealing effect, can avoid the leakage of flange connections in pipeline completely.
Accompanying drawing explanation
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, sealing body; 6-1, upper cirque body; 6-2, lower cirque body; 6-3, circumference body; 7, sealing sponge; 8, O-ring seal.
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 flange installation structure of high-voltage tube, comprise oil pipe I1, the mouth of pipe of oil pipe I1 is welded with flange I2, the other end of flange I2 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.Sealing body 6 is installed on described flange I2, described sealing body 6 comprises the upper cirque body 6-1 that is connected with flange I2, be contained in lower cirque body 6-2 on flange II4 outer circumferential face with upper cirque body 6-1 parallel sleeve, be connected the circumference body 6-3 of cirque body 6-1 and lower cirque body 6-2, the inner side of described circumference body 6-3 is provided with the sealing sponge 7 of ring, between described sealing sponge 7 and described upper cirque body 6-1 and sealing sponge 7 and lower cirque body 6-2, is equipped with O-ring seal 8.In the present embodiment, fastening piece 3 is screw.
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, within all dropping on protection domain of the present utility model.
