Abstract
A flexible connecting device for an inlet/outlet pipeline of a petroleum product storage tank is applied to safe and flexible connection at an inlet/outlet of the petroleum storage tank. A middle union pipe and the inlet/outlet pipeline of the petroleum product storage tank are identical in the inner diameter; bellows are welded respectively at both ends of the middle union pipe; union pipes are welded respectively at the other ends of the two bellows; flanges are welded respectively at the other ends of the two union pipes; reinforcing rings are sleeved on the outer walls of the bellows; annual plates are arranged respectively at the ends of the bellows; fixing holes are distributed in the annual plates; both ends of short screws pass through the fixing holes in the annual plates respectively; nuts are fixed at both ends of the short screws; pull rod holes are uniformly distributed in the annual plates on the outer sides of the two bellows; a long pull rod passes through the pull rod holes in the annual plates on the outer sides of the bellows; and both ends of the long pull rod are fixed with nuts. The flexible connecting device has the benefit of compensating transversal displacements of single-plane or multiple-plane curved pipe sections by being connected onto the inlet/outlet pipeline of the storage tank.
Description
Technical field
The utility model relates to the petroleum storage tank technical field, and particularly oil product storage tank imports and exports safety connection set is that a kind of large-scale oil product storage tank is imported and exported the Flexible Safety connection set.
Background technique
At present, the construction of domestic crude oil, product oil warehouse development is rapid, and the tank designs building technology has also been obtained rapidly rapidly.
For large-scale storage tank, import and export if adopt rigid pipe to connect then on-the-spot difficult installation; If phenomenons such as earthquake, tank body sedimentation take place, the joint is damaged, cause leakage, there is potential safety hazard.For the danger that the sedimentation that prevents storage tank causes, it is imported and exported generally all should be provided with and flexibly connects.At present domestic main employing metallic hose is as the big jar of flexible connection mode of importing and exporting, and this Placement can effectively reduce the radial and axial stress of storage tank.But when the big and intensity of earthquake of their location of pipeline caliber was higher, the length of flexible pipe can increase greatly, had increased the uncertainty on the difficulty installed and the safety.
The model utility content
The purpose of the utility model is: provide a kind of oil product storage tank to import and export the pipeline flexible connecting device, can be connected the import and export of crude oil, product oil storage tank, reduce large-scale storage tank and import and export the length that flexibly connects, improve the Security of storage tank.
The technological scheme that the utility model adopts is: oil product storage tank is imported and exported the pipeline flexible connecting device; Comprise flange, connecting tube, bellows, intermediate connection tube, long draw, stiffening ring, annular slab and short screw; It is characterized in that: the internal diameter of intermediate connection tube is identical with the internal diameter that oil product storage tank is imported and exported pipeline; Two ends at intermediate connection tube are welded with bellows respectively, are welded with connecting tube respectively at the other end of two bellowss, are welded with flange respectively at the other end of two connecting tubes; On the outer wall of described bellows, be with stiffening ring, at the two ends of two bellowss annular slab arranged respectively, on annular slab, all be distributed with fixed hole, the fixed hole on the annular slab is passed at the two ends of short screw respectively, is fixed with nut at the two ends of short screw; On the annular slab in two bellows outsides, be evenly distributed with tie rod hole, long draw passes the tie rod hole of bellows exterior annular plate, and is fixed with nut at the two ends of long draw.
The internal diameter of described flange, connecting tube, bellows and intermediate connection tube is identical.
Because long draw and short screw can bear the effect of pressure, thrust and other additional external force; Press thrust in bellows self absorbs, can not produce external force, so the pipeline at bellows two ends can use center fixed support or guiding trestle pipeline; Reduce construction cost, improve efficiency of construction.
The beneficial effect of the utility model: the utility model oil product storage tank is imported and exported the pipeline flexible connecting device; Connecting storage tank imports and exports on the pipeline; The lateral displacement of compensation single plane or many plane bendings pipeline section; Especially import and export the pipeline bore when big for storage tank, adopt metallic hose to install when inconvenient as flexible connecting device.
