Description
Technical field
The present invention relates to high pressure flange, specifically a kind of high pressure flange linkage structure for connecting ultra-high pressure pipeline and valve block hydraulic fluid port.
Background technique
Flange joint is the usual way that valve body is connected with pipeline, and it is linked together by the flange screw of the screw hole on valve body and pipe fitting end, is applicable to the large-flow hydraulic system of more than latus rectum 32mm.
Fig. 1 is that display conventional valve block and pipeline are by the schematic diagram of Flange joint.As shown in Figure 1, conventional high-tension flange 200 is welded on the end of relative pipeline 100, and on flange, the place of keeping to the side is formed with multiple holes of constant spacing to hold bolt 300, and bolt 300 is connected with valve block end screw thread again.So, 300 will realize the connection of valve block and pipeline by tighting a bolt.
This Placement is simple and practical, general pressure within 20MPa, according to standard in actual applications most high energy reach 40MPa, to be connected with pipeline more than the valve block of 40Ma and just must to design special non-standard adpting flange, to reach sealing and the effect be connected.Therefore, there is significant limitation in high-pressure hydraulic application in this conventional high-tension flange connection.
Summary of the invention
The present invention is intended to solve above-mentioned high-pressure pipeline flange and connects and sealing problem, and provides the high pressure flange linkage structure of a kind of ultra-high pressure pipeline and valve block hydraulic fluid port.
The present invention solves described problem, and the technological scheme of employing is:
A kind of high pressure flange linkage structure, comprises high pressure flange, pipeline, valve block, also comprises: an adapter with ladder head of assembling with high pressure flange, multiple stud supporting with high pressure flange edge equidistant hole and tightening nut thereof; Described adapter outside dimension and high pressure flange internal diameter size match, and take over and weld with pipe end through after high pressure flange, and the ladder head of adapter is docked with valve block by sealing transition plate and gasket seal; Described stud one end is connected through the Kong Houyu tightening nut of high pressure flange edge, the stud the other end is connected by the tapped hole that screw thread is corresponding with on valve block, tightens tightening nut and makes described high pressure flange, adapter, valve block three be tightly connected and be integrated.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
Utilize flange connection of the present invention, large discharge Superhigh Pressure Hydraulic System valve block can be realized and be connected with the quick of pipeline.As can be seen from the component after split, each several part of this Placement is all convenient to processing and installs, and does not have numerous and diverse component and job step, effectively can resolve extra high voltage system sealing and intensity two hang-up.Meanwhile, this kind of flange connection is strong at high pressure domain generality, and applied widely, seal degree is high, and cost is low, suitable popularization.
As preferably, the present invention further technological scheme is:
Described sealing transition plate both sides all have ring packing groove near barycentric subdivision, and described gasket seal size is corresponding with described ring packing groove dimensions, in the ring packing groove of gasket seal embedding sealing transition plate both sides.
Described gasket seal is annealing red copper pad, and its internal diameter size is greater than adapter internal diameter size.
Above-mentioned preferred version, mainly allows the inwall direct contact medium of gasket seal, this is done to avoid red copper pad when being subject to the extruding of stud pretightening force, red copper pad can not be squeezed in pipeline.
Sealing transition plate separates adapter and seal groove, makes flange just can change sealing when not dismantling pipeline and flange when changing sealing.
