Technical Field

The invention belongs to the technical field of oil tank inner floating discs, and particularly relates to an oil tank inner floating disc.

Background

For various petrochemical liquids such as diesel oil, gasoline and the like, the volatile liquid is easy to volatilize, in order to reduce the volatilization loss of a liquid medium stored in an oil storage tank, and avoid the oil gas formed by volatilization (such as the oil gas formed by the volatilization of the gasoline) from being emitted to the outside of the oil storage tank to cause serious environmental pollution and potential safety hazard, at present, an inner floating disc is arranged on the liquid medium in an oil tank and correspondingly ascends and descends along with the liquid level height of the liquid medium, so that the volatilization of the liquid medium in the oil storage tank can be effectively prevented.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the oil tank inner floating disc which has better sealing effect, prolongs the service life and is convenient to disassemble and assemble.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a floating plate in oil tank, is including floating unit and connecting device, floating unit includes body and apron, the body is including being used for inlaying the cavity of dress apron, the lateral wall of body corresponds the laminating with the lateral wall of apron and forms the connecting band when being used for the unit concatenation of floating, the connecting band cooperates the concatenation in order to realize floating the unit with connecting device, connecting device includes detachable clamping fastener, multidirectional connector and is used for locking clamping fastener and/or the locking Assembly of multidirectional connector, clamping fastener lock is on the connecting band of adjacent both sides floating unit, clamping fastener extends along the splice seam direction of both sides connecting band, multidirectional connector is used for splicing at least three floating unit, multidirectional connector overcoat is in the outside of clamping fastener.

Adopt above-mentioned scheme, at first, through the unit that floats of constituteing by body and apron, and form the connecting band after the lateral wall of body and the lateral wall laminating of apron, its thickness of lateral wall that the connecting band that forms this moment compares single body is thicker, consequently under the sealed mode that adopts hard seal, connecting band non-deformable, thereby the leakproofness of hard seal has been improved, and then can reduce soft seal (need not the resistant oil seal strip among the prior art), the installation effectiveness is improved, such benefit still lies in the wall thickness that can alleviate the body, thereby make the body quality lighter, buoyancy on fluid is better. In the technical scheme, the connecting bands of the floating units on two adjacent sides can be fixedly connected through the fastening mode of the clamping fastener, so that the sealing path between the two floating units is tighter, and the sealing capability of hard sealing is improved; on the other hand, the contact surface of the inner wall of the clamping fastener and the connecting belt can form a prolonged sealing path, so that the purpose of further reducing oil gas leakage is achieved.
