The invention discloses a hydraulic flange which comprises a hydraulic end flange (1) and a fixing end flange (2). The hydraulic flange is characterized in that hydraulic channels (3), a plurality of hydraulic cavities (4) and a hydraulic tube connector (5) are arranged inside the fixing end flange (2); the hydraulic channels (3) among the plurality of hydraulic cavities (4) are communicated together; the hydraulic channels (3) are communicated with the hydraulic tube connector (5); a plurality of threaded holes corresponding to the hydraulic cavities are formed in the fixing end flange (2). By adoption of the hydraulic flange, the working efficiency can be improved, and the purpose of fastening all hydraulic tension bolts at a time is achieved.
Description
Technical field
The present invention relates to field of mechanical technique, relate in particular to a kind of hydraulic flange.
Background technique
Flange joint is the very general releasable connection mode of a kind of application, and hydraulic flange adopts hydraulic tensile bolt to carry out fastening.The working principle of hydraulic tensile bolt utilizes hydraulic jack directly to apply external force to bolt, make the bolt of the power that is applied in its resiliently deformable (stretching), after bolt is stretched, locking nut is tightened onto on the relevant position of bolt tension length, then makes bolt produce resiliently deformable (contraction) by oil hydraulic cylinder release and reach firm object.Oil hydraulic cylinder is positioned at the position of bolt medial axis, for carrying out axial tension to bolt, realizes the amount of tension that bolt needs.And this amount of tension of bolt determines the clamping force needed for bolton just.After hydraulic tensile bolt is pressurizeed by hydraulic coupling, bolt is stretched, and fastening nut and junction plane are close to simultaneously.Bolt is made to produce resiliently deformable (contraction) thus be locked by the axial deformation of bolt by oil hydraulic cylinder release.
The assembly method of existing hydraulic tensile bolt on flange can only one one assembling hydraulic tensile bolt, the workpiece that the method i.e. applicable hydraulic tensile bolt difformity applied widely is arranged, but working efficiency is low; Cannot realize once assembling all hydraulic tensile bolt, thus its utilization is restricted greatly.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and the one that provides can be increased work efficiency, realize once the hydraulic flange of fastening all hydraulic tensile bolt.
A kind of hydraulic flange of the present invention, comprises hydraulic pressure end flange, fixed end flange, and wherein: hydraulic pressure end flange is provided with hydraulic channel, some hydraulic pressure cavity, hydraulic fitting, between some hydraulic pressure cavity, hydraulic channel is communicated with, and hydraulic channel is communicated with hydraulic fitting.
Above-mentioned a kind of hydraulic flange, fixed end flange is provided with the some tapped holes corresponding with hydraulic pressure cavity.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: a hydraulic channel and some hydraulic pressure cavity are set in hydraulic pressure end flange of the present invention, fixed end flange is provided with the some tapped holes corresponding with hydraulic pressure cavity, make all bolts on fastening piece stretch (resiliently deformable) by hydraulic coupling (fastening required clamping force) and recover distortion and reach disposable fastening object simultaneously, equably with hydraulic pressure, thus substantially increase working efficiency.

Embodiment
Below in conjunction with preferred embodiment, to the hydraulic flange proposed according to the present invention, its embodiment, structure, feature and method thereof, be described in detail as follows.
Participate in Fig. 1-5, hydraulic flange of the present invention, comprise hydraulic pressure end flange 1, fixed end flange 2, wherein:, hydraulic pressure end flange 2 is provided with hydraulic channel 3, some hydraulic pressure cavity 4(be used for install hydraulic bolt), hydraulic fitting 5, between some hydraulic pressure cavity 4, hydraulic channel 3 is communicated with, and hydraulic channel 3 is communicated with hydraulic fitting 5; Fixed end flange 2 is provided with the some tapped holes 6 corresponding with hydraulic pressure cavity.
working principle:see Fig. 6, fix on each double end hydraulic bolt 7 tapped hole 6 being first arranged on fixed end, add gasket seal, again the hydraulic pressure lumen pore of hydraulic pressure end flange is aimed at each stud bolt to put, and install hydraulic element and the locking nut of each hydraulic pressure cavity, first each pair of screw nut is applied mechanically hand and turn round same position, then locking nut hand is tightened.
Check whether the pointer of hydralic pressure gauge makes zero, and the two ends of hydraulic tube be connected to respectively the hydraulic fitting 5 of oil hydraulic pump and hydraulic flange and tighten, prexxure of the hydraulic pump control valve adjusts to the force value (as 100.0MPa) required for institute's mounting flange bolt.Primer fluid press pump, when hydraulic pump works is to the force value set, oil hydraulic pump can stop pressurize automatically, now all on hydraulic flange bolts all can be stretched certain length extending to hydraulic pressure end, and locking nut can occur an intersegmental gap (Here it is bolt be stretched length) with the end face of hydraulic flange hydraulic pressure end.Tighten locking nut with hand, open pressure-relief valve slowly unload be pressed onto gauge hand zero till, remove hydraulic oil pipe, after being covered by the hydraulic fitting 5 of hydraulic pressure end on hydraulic flange, hydraulic flange installs.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (2)
