Abstract
The utility model discloses a double sealing device positioned between an outer ring of the inner floating roof and a storage tank wall. The device comprises an inner ring positioned at the end of the outer floating roof and an outer ring positioned at the external part of the inner ring. A support beam is positioned between the inner ring and the outer ring. The end of the outer floating roof between the outer ring and the storage tank wall is equipped with a bladder-type primary seal. The upper part of the bladder-type primary seal is equipped with a tongue-shaped secondary seal. The tongue base of the tongue-shaped secondary seal is positioned at the connecting part of the support beam and the outer ring. The tongue tip of the tongue-shaped secondary seal comes in contact with the storage tank wall. The double sealing device has the advantages of solving the problem of the existing technology, ensuring the lifting stability of the inner floating roof and simultaneously increasing the sealing reliability of the outer ring of the inner floating roof, and achieving the higher and tightened requirements of the peripheral sealing of the inner floating roof.
Description
Technical field
The utility model relates to a kind of seal ring, and in particular, the utility model relates to a kind of sealing arrangement that is used between interior floating plate outer ring and the storage tank shell.
Background technology
At present, floating plate all adopts single hermetically-sealed construction in the domestic major part, described single hermetically-sealed construction is divided into ligulate and two kinds of forms of capsule formula, wherein: ligulate leak free elasticity is very good, can be close to storage tank shell when interior floating plate lifting freely overturns, and the friction force during the floating plate lifting in can not increasing, good air seal effect is also arranged simultaneously; The sealing of capsule formula then possesses very good sealing, fixing and anti-transposition performance, it wraps up huge foam and its compression is even by the sheet adhesive tape, big with the area of contact of storage tank shell, when interior floating plate lifting, evenly stressed effect can be played, the local deformation problem and the excessive interior floating plate displacement problem that causes of solvent flow rate of storage tank shell can be easily tackled.Though that aforesaid two kinds of single hermetically-sealed constructions all have is wear-resisting, oil resistant, conduction, high tenacity, high resiliency, ageing-resistant characteristics, and can reach safe and reliable sealing effectiveness in the ordinary course of things, but when the peripheric sealing of internal floating plate have higher, more during exacting requirements, single hermetically-sealed construction has not just prove effective.
The utility model content
Problem to be solved in the utility model addresses the above problem exactly, thereby provides a kind of peripheric sealing that can reach internal floating plate that double sealing structure higher, that more be strict with is arranged.
Double seal in the utility model is used between floating plate outer ring and the storage tank shell, comprise the inner ring that is arranged on outer floating drum port and be arranged on the exterior outer ring of described inner ring, be provided with support beam between described inner ring and the outer ring, the utility model difference with the prior art is: the port of described outer floating drum is provided with capsule formula once sealing between outer ring and storage tank shell, the top of described capsule formula once sealing is provided with the ligulate secondary seal, the root of the tongue portion of described ligulate secondary seal is arranged on the junction of described support beam and outer ring, and the lip of the tongue of described ligulate secondary seal contacts with described storage tank shell.
The beneficial effects of the utility model are: solved the problem that prior art exists, provide a kind of peripheric sealing that can reach internal floating plate that double sealing structure higher, that more be strict with is arranged.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below be in conjunction with the accompanying drawings to the detailed description of technical solutions of the utility model:
As seen from the figure, double seal in the utility model is used between floating plate outer ring and the storage tank shell, comprise the inner ring 6 that is arranged on outer floating drum 7 ports and be arranged on described inner ring 6 exterior outer rings 1, be provided with passive support beam 5 between described inner ring 6 and the outer ring 1, the formation situation of described double seal is: earlier floating drum 7 fixedly mounts capsule formula once sealing 3 between the outer ring 1 of liquid level 2 above ports and storage tank shell 8 described outside, again at the top of described capsule formula once sealing 3 fixed installation ligulate secondary seal 4, the root of the tongue portion of described ligulate secondary seal 4 is arranged on the junction of described support beam 5 and outer ring 1, and the lip of the tongue of described ligulate secondary seal 4 contacts with described storage tank shell 8.
The floating plate outer ring was compared with existing single sealing arrangement with the double seal between the storage tank shell and is had following advantage in the utility model was used for:
(1) because each advantageous ligulate and two kinds of single hermetically-sealed constructions of capsule formula are combined, make it in guaranteeing, in the floating plate lifting smoothness, increase interior floating plate outer ring leak free reliability;
(2) because simultaneously, utilized the characteristics of ligulate hermetically-sealed construction again, made it when interior floating plate lifting is turned over, can prevent that the impurity dust from entering solvent by actv., solved the problem that original single sealing arrangement incorporates impurity easily at capsule formula leak free;
(3) because two kinds of single hermetically-sealed constructions are organically combined, and utilized its advantage separately, thereby better saved the energy, actv. has reduced environmental pollution simultaneously.
Below schematically the utility model and embodiment thereof are described, this description does not have restricted, and shown in the accompanying drawing also is one of embodiment of the present utility model.If those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim,, all should belong to protection domain of the present utility model without creationary structure similar and the embodiment of designing to this technical scheme.
Claims (1)
- One kind be used in double seal between floating plate outer ring and the storage tank shell, comprise the inner ring that is arranged on outer floating drum port and be arranged on the exterior outer ring of described inner ring, be provided with support beam between described inner ring and the outer ring, it is characterized in that: the port of described outer floating drum is provided with capsule formula once sealing between outer ring and storage tank shell, the top of described capsule formula once sealing is provided with the ligulate secondary seal, the root of the tongue portion of described ligulate secondary seal is arranged on the junction of described support beam and outer ring, and the lip of the tongue of described ligulate secondary seal contacts with described storage tank shell.
