Abstract
The utility model relates to a double-flange load transfer joint which comprises an outer telescopic tube with a flange coupling end and an inner telescopic tube. The utility model is characterized in that an annular sealing ring is arranged between the outer telescopic tube and the inner telescopic tube and is tightly screwed via a press cap with a flange and nuts, and the cross-section of the annular sealing ring is in a trapezoid structure. The press matching surfaces of the outer telescopic tube, the press cap and the trapezoidal sealing ring are all in a slope structure, limited bolts penetrate through holes on each flange and are directly combined with an outer tube, and the limited bolts are tightly screwed via corresponding nuts. The utility model adopts the trapezoidal sealing ring, the matching contact surfaces of the outer telescopic tube, the press cap and the sealing ring are all processed into corresponding slopes, the slopes can be properly adjusted via pressure bolts according to different media pressure, and the utility model can improve the use effect of telescopic pipe joints. The utility model has the characteristics that the joint not only can assure excellent sealing effect, but also can adjust sealing condition in time. The utility model has convenient dismounting and can compensate the displacement amount of pipelines in a certain range. The utility model can also transfer axial force to the entire pipelines and has the protection function on pumps, valves, etc.
Description
(1) technical field
The utility model relates to pipe coupling, particularly relates to two flange force transmission joints that can compensate displacement, dislocation and deflection in the pipeline certain limit, and it mainly is applicable to being connected of pipelines such as conveying water, oil, gas and particle powdery medium.
(2) background technique
Existing pipe coupling with Telescopic has multiple structure, its sealability also respectively has quality, wherein a kind of pipe coupling commonly used, form by outer telescopic tube and interior telescopic tube, be provided with O-ring seals between the two and reach sealing, very easily cause its seal failure in actual use because of the telescopic displacement of pipeline enclosure changes, in case and the O-ring seals ageing failure, just can't adjust and remedy, so that cause integral body to scrap.
(3) summary of the invention
The purpose of this utility model designs at existing deficiency in the above-mentioned prior art just a kind ofly has good seal performance and can carry out scene adjustment, displacement, dislocation and deflection in the pipeline certain limit can be compensated, two flange force transmission joints of whole pipe can be given axial force transmission.
The purpose of this utility model realizes by following scheme: this pair flange force transmission joint comprises the outer flexible sleeve that has the flange coupling end, the interior telescopic pipe that the one end is installed in the outer flexible sleeve, the other end also has the flange coupling end, wherein: be provided with O-ring seal between flexible sleeve and the interior telescopic pipe outward, and tighten up by gland and the nut that has flange, the cross section of its O-ring seal is a trapezium structure; The compression fit face of outer flexible sleeve, gland and trapezoidal seal ring is ramp structure; The through hole that caging bolt passes on each flange directly combines with Outer Tube, and tighten up by corresponding nut.
In the utility model, gland and outside be provided with hold-down bolt between the flexible sleeve.
Working principle of the present utility model is by bolt expansion joint and valve or pipeline to be coupled together, make its one-tenth as a whole, and certain displacement amount arranged, so just can be when installation and maintenance, adjust according to on-the-spot installation dimension, when work, can be axial force transmission to whole pipe, not only can increase work efficiency, and equipment such as pump, valve are played the certain protection effect; By hold-down bolt and platen trapezoidal seal ring is applied suitable pressure, make trapezoidal seal ring produce distortion, make it to form certain seal pressure, realize the sealing effect of force transmission joint.
The utility model adopts trapezoidal seal ring, and flexible outward sleeve, gland all are processed into corresponding inclined-plane with the surface of contact that cooperates of seal ring, in the process that realizes sealing, can do suitable adjustment by hold-down bolt according to the difference of pressure medium, improve the using effect of flexible pipe coupling widely.Characteristics of the present utility model are: can guarantee good sealing effect, can in time adjust sealing condition again, convenient disassembly, and the better compensation pipes displacement amount within the specific limits of energy; Also can give whole pipe, pump, valve etc. is played a protective role axial force transmission.
(4) description of drawings
Accompanying drawing is a structural front view of the present utility model.
(5) embodiment
The utility model is done below in conjunction with accompanying drawing and is described in further detail:
As shown in the figure: this pair flange force transmission joint comprises the outer flexible sleeve (1) that has the flange coupling end, the interior telescopic pipe (4) that the one end is installed in the outer flexible sleeve, the other end also has the flange coupling end, wherein: be provided with O-ring seal (2) between flexible sleeve (1) and the interior telescopic pipe (4) outward, and tighten up by gland (3) and the nut (6) that has flange, the cross section of its O-ring seal is a trapezium structure; Outer flexible sleeve (1), gland (3) are ramp structure with the compression fit face of trapezoidal seal ring (2); The through hole that caging bolt (5) passes on each flange directly combines with Outer Tube, and tightens up by corresponding nut (6), gland (3) and outside be provided with hold-down bolt (7), hold-down bolt (7) and the alternate layout of caging bolt (5) between the flexible sleeve (1).
Claims (2)
1, a kind of pair of flange force transmission joint, it comprises the outer flexible sleeve (1) that has the flange coupling end, the interior telescopic pipe (4) that the one end is installed in the outer flexible sleeve, the other end also has the flange coupling end is characterized in that:
A, be provided with O-ring seal (2) between flexible sleeve (1) and the interior telescopic pipe (4) outward, and by having flange
Gland (3) and nut (6) tighten up, the cross section of its O-ring seal (2) is a trapezium structure;
B, flexible sleeve (1), gland (3) are ramp structure with the compression fit face of trapezoidal seal ring (2) outward;
The through hole that c, caging bolt (5) pass on each flange directly combines with Outer Tube, and pass through corresponding nut
(6) tighten up.
2, according to claim 1 pair of flange force transmission joint is characterized in that: gland (3) and outside be provided with hold-down bolt (7) between the flexible sleeve (1).
