Abstract
The utility model discloses a composite rubber water sealer of a water conservancy gate, which comprises a water sealing body and a chlorinated polyether modification special rubber (PNBR) layer, wherein the water sealing end of the water sealing body forms a circle shape. The surface of the water sealing body is laid with the chlorinated polyether modification special rubber (PNBR) layer. The water sealing end of the water sealing body can also form a square shape. The utility model has the characteristics of reasonable design, simple manufacturing technology, long service life and small friction coefficient. The utility model is suitable for the modification of various water conservancy gates.
Description
Technical field
The utility model relates to the water seal of water conservancy gate, refers more particularly to the water seal of water conservancy gate compounded rubber.
Background technology
At present, the water seal of water conservancy gate is commonly used two classes, and a class is a rubber water sealing, and its advantage is a good springiness, but friction factor is big, and anti-wear performance is poor; Another kind of is that glue is moulded composite water block, as rubber and polytetrafluoroethylene (PTFE) composite water block, though wear-resisting problem is in use peeled off easily and caused gate to leak, and production technology complexity comparatively.
Summary of the invention
Goal of the invention of the present utility model, being to provide a kind of can effectively overcome the problems referred to above, good integrity, long service life, technology is easy, the water conservancy gate compounded rubber water seal that friction factor is little.
The technical solution of the utility model is such, and the water seal of water conservancy gate compounded rubber comprises water seal body and polyether chloride modified special rubber (PNBR) layer; The water seal end of described water seal body is circular, is laid with described polyether chloride modified special rubber (PNBR) layer on the surface of described water seal body.
The water seal end of described water seal body is square, is laid with described polyether chloride modified special rubber (PNBR) layer on the surface of described water seal body.
Characteristics of the present utility model are reasonable in design, and technology is easy, good integrity, and long service life, friction factor is little.Be fit to repacking, the use of all kinds of water conservancy gates.
Description of drawings
Fig. 1 shows schematic diagram for cuing open of circular water conservancy gate compounded rubber water seal.
Fig. 2 shows schematic diagram for cuing open of square water conservancy gate compounded rubber water seal.
Wherein: 1 water seal body, 2 polyether chloride modified special rubbers (PNBR) layer.
The specific embodiment.
That the utility model provides is circular water conservancy gate compounded rubber water seal and two kinds of embodiment of square water conservancy gate compounded rubber water seal.
Shown in accompanying drawing 1,2, the water seal of water conservancy gate compounded rubber comprises that (polyether chloride modified special rubber is my patent of invention, the patent No.: 99121126.X) for water seal body 1 and polyether chloride modified special rubber (PNBR) layer 2.The water seal end of described water seal body 1 is circular, is laid with described polyether chloride modified special rubber (PNBR) layer 2 on the surface of described water seal body 1.They are by HTHP sulfuration all-in-one-piece.
The water seal end of described water seal body 1 is square, is laid with described polyether chloride modified special rubber (PNBR) layer 2 on the surface of described water seal body 1.They also are by HTHP sulfuration all-in-one-piece.
Claims (2)
1, water conservancy gate compounded rubber water seal, it comprises water seal body (1); It is characterized in that it also comprises polyether chloride modified special rubber (PNBR) layer (2); The water seal end of described water seal body is circular, is laid with described polyether chloride modified special rubber (PNBR) layer (2) on the surface of described water seal body (1).
2, water conservancy gate compounded rubber according to claim 1 water seal, it is characterized in that, the water seal end of described water seal body (1) also can be laid with described polyether chloride modified special rubber (PNBR) layer (2) for square on the surface of described water seal body (1).
