In addition; in our daily life often many accidents can appear; combat a natural disaster in the face of speedily carrying out rescue work that middle generation chemical industry is poisonous, the emergent occasions such as operation are speedily carried out rescue work in the leakage of harmful gas pipeline, the blowout of oil gas field, the repairing of high voltage power transmission and transforming, the explosion of water-feeding ﹠ drainaging pipeline, hull damage, high-altitude; all need within the fastest time period, accomplish to finish fast, thereby avoid or reduce the generation of the dangerous situations such as blast, poisoning, fire and environmental pollution.
The model utility content
For the technological deficiency that above-mentioned conventional flange exists, the utility model aims to provide a kind of quick, non-manual hydraulic flange.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic flange, comprise flange body, connecting bolt, and described flange body is I-shaped structure, and top and the bottom are flange plate, and the centre is connecting pipeline; Be provided with one group at the connecting end surface place of upper flange dish and axially run through attachment hole, running through attachment hole is that the star equal angles distributes;
Also be provided with one group at the connecting end surface place of lower flange dish and axially run through attachment hole, run through attachment hole and be similarly the distribution of star equal angles; Running through attachment hole is multi-stage stepwise concentric hole, is provided with the restraining groove of seal ring, spring, connecting bolt in the inboard of running through attachment hole;
Run through between attachment hole inboard and the cylindrical wall at each lower flange dish and radially to be provided with exhaust port;
Run through to be provided with between the attachment hole at each lower flange dish and run through oilhole;
Described connecting bolt is a composite component, comprise piston rod nut, piston rod double-screw bolt, turnbuckle, belleville spring, tightening nut, the piston rod double-screw bolt is a cascade cylindrical body, its upper end is for connecting the axial outside thread of piston rod nut, the lower end is provided with the axial internal thread that connects turnbuckle, and the other end of turnbuckle and tightening nut are flexibly connected;
Run through to be provided with connecting bolt in the attachment hole at each lower flange dish, be flexibly connected by threaded fasteners and flange plate; Be provided with the support gasket ring of exterior seal ring in the band between connecting bolt and the threaded fasteners.
Radially be provided with the hydraulic pressure valve opening that runs through the attachment hole perforation more than with flange plate at lower flange Pan Waiyuanbi.
Described upper lower flange connecting end surface is provided with the metal sealing ring recess.
Be provided with one group of O RunddichtringO on the described piston rod double-screw bolt.
The utility model has changed the pure bolt connecting mode of conventional flange, the flange that the quick transmission mechanism of hydraulic pressure is applied to pipeline connects, pipeline and pumping plant for petrochemical industry large pore, ultrahigh pressure, many bolts are realized Rapid tooling, not only save manpower and time, and accomplish the consistent stress equalization of connecting end surface moment of torsion for numerous bolts, pipeline sealing is high-strength, especially running into pipeline burst, case of emergency, can accomplish quick disposal, can be widely used in petrochemical industry exploitation, the transfer line.
