Abstract
A kind of board-like large compensation elastic mechanical sealing structure including setting gradually with lower component from bottom to up：Filler strip；Cycle beam；First primary liner；Film is supported；Second primary liner；Primary membrane；3rd primary liner；Latch plate；Filler plate；Crawler shoe plate；Protection device packing ring；And baffle plate.The board-like large compensation elastic mechanical sealing structure good sealing effect, compensation rate is big, and strong adaptability is simple to manufacture, easy for installation, and service life is long.
Description
Technical field
The utility model is related to a kind of board-like large compensation elastic mechanical sealing structure.
Background technology
At present, floating plate is inserted close using double sealing structure, Mechanical shoes type sealing structure and liquid in most domestic
Seal structure, described double sealing structure is the combining form of bellows and tongue type, wherein：Bellows sealing wraps up rectangle by sheet adhesive tape
Foam is simultaneously compressed it uniformly, is contacted with tank skin；Tongue type sealing structure is positioned on bellows sealing, can be when interior floating plate is lifted
Tank skin is adjacent to freely to invert；Floating plate long-play in tank, can cause bellows sealing structure oil-feed, and tongue type sealing structure is turned over
Turn not freely, and then influence sealing effectiveness；The Mechanical shoes type sealing structure be combined by mechanical arm, latch plate and diaphragm seal and
Into its compensation rate to tank skin is small, and the ovality to tank requires high；Liquid is inserted to be sealed in the motion of interior floating plate, is held
Easily by the defect scratch in tank skin, liquid easily flows out medium in pollution tank in sealing.
Therefore, in order to solve many not enough and defects of above-mentioned prior art, so as to provide a kind of board-like large compensation elasticity
Mechanical seal structure.The sealing structure is simple, design science reasonable, can effectively reduce the evaporating loss of oil product, has saved oil
Security is improved while product.
Utility model content
The utility model is completed in view of at least one above mentioned problem, and a purpose of the present utility model is
A kind of board-like large compensation elastic mechanical sealing structure is provided.The board-like large compensation elastic mechanical sealing structure include from bottom to up according to
Secondary setting with lower component：Filler strip；Cycle beam；First primary liner；Film is supported；Second primary liner；Primary membrane；3rd is primary
Pad；Latch plate；Filler plate；Crawler shoe plate；Protection device packing ring；And baffle plate.
According to the utility model on the other hand, the first to the 3rd primary liner is made up of nitrile butadiene rubber.
According to the utility model on the other hand, the primary membrane and protection device packing ring are made up of polytetrafluoroethylene (PTFE).
According to the utility model on the other hand, the filler strip is made up of galvanized steel.
According to the utility model on the other hand, the described first to the 3rd primary liner is formed as liner.
Compared with prior art, the beneficial effects of the utility model are：
The utility model good sealing effect, compensation rate is big, and strong adaptability is simple to manufacture, easy for installation, and service life is long.
