Abstract
The utility model discloses a complex water seal which comprises a water seal body and a plastic sheet arranged on the water seal body. The utility model replaces the gluing mode for binding a tetrafluoroethylene belt and rubber with mould pressing mode for binding the plastic sheet and rubber, thus simplifying the production process, improving the integrity of the water seal, reducing the friction factor and prolonging the service life of the water seal. The complex water seal is suitable for modification and application of various water gates.
Description
Technical field
The utility model relates to a kind of water seal, and particularly relevant for a species complex water seal.
Background technology
The effect of water seal is to prevent to leak, and is an important component part of hydroelectric project gate.Be used in the P type that the is generally water seal on the gate on the flood control engineering, the gate water seal is the crucial accessory of all kinds of steel gate sealings in the Hydraulic and Hydro-Power Engineering, and the height of its quality level had both influenced the safe operation of hydraulic gate, also influenced the safety of hydraulic structure.Therefore select the water seal of adaptation extremely important according to character, the operation condition of various gate.
At present, water conservancy, the employed water seal of water power unit in charge of construction mainly are gum water seal and rubber and plastic composite water block.
The gum water seal is because the various reasons of rubber material self property though have excellent sealing performance in its application facet, is convenient to transportation, operate also more convenient, its friction factor height, easy to wear.Influence workmanship and application life, particularly the gate of often opening very easily damages, and needs often to change, and causes great waste.
The reinforced TFE film adhesive that hangs down frictional resistance, high abrasion is sticked at water seal water sealing operation face then be referred to as the water seal of rubber and plastic complex, though solved gum water seal friction factor height, problem easy to wear, but be easy to cause the cracking between polytetrafluoroethylene floor and the rubber under the case of bending, the packing instructions height, cost of transportation is big, and complex manufacturing.
To sum up reason is badly in need of a kind of novel water seal and is substituted original water seal, in order to satisfy the demand of different water conservancies, water power unit in charge of construction.
The utility model content
The utility model proposes a species complex water seal, its mode with mold pressing between sheet and the rubber has replaced tetrafluoroethene band and the gluing mode of rubber, has reduced friction factor, has strengthened abrasion resistance, has prolonged application life.
The utility model includes water seal body and sheet, and sheet is arranged on the water seal body.
In the utility model, the water seal body has a water sealing operation face, and the upper surface of sheet and water sealing operation face are on same horizontal plane.
In the utility model, the water seal body is the water seal of P type, comprises head and limb arm, and head and limb arm connect into P shape, and the head of P type water seal has a through hole.
The utility model has replaced tetrafluoroethene band and the gluing mode of rubber in the mode of mold pressing between sheet and the rubber, simplify production technology, improved globality, reduced friction factor, prolong long service life, and be fit to repacking, the use of all kinds of water conservancy gates.

Figure 1 shows that stereogram according to the complex water seal of the utility model one embodiment.
Figure 2 shows that schematic diagram according to the water seal body of the utility model one embodiment.
Figure 3 shows that schematic diagram according to the sheet of the utility model one embodiment.
Figure 4 shows that sectional drawing according to the complex water seal of the utility model one embodiment.
The specific embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Figure 1 shows that stereogram according to the complex water seal of the utility model one embodiment.Complex water seal 100 comprises water seal body 10 and sheet 20.Figure 2 shows that the schematic diagram according to the water seal body of the utility model one embodiment, as shown in Figure 2, the water seal body 10 in the present embodiment is a P type water seal, shown in water seal body 10 have head 11 and limb arm 12, and head 11 and limb arm 12 connect into P shape.Head 11 has a water sealing operation face 111, and head 11 has a through hole 112, and through hole 112 makes water seal body 10 have better elasticity.Figure 3 shows that schematic diagram according to the sheet of the utility model one embodiment.Sheet 20 is arranged on the water seal body 10, and the upper surface of sheet 20 and water sealing operation face 111 are on same horizontal plane.Figure 4 shows that sectional drawing according to the complex water seal of the utility model one embodiment.
In the present embodiment, water seal body 10 and sheet 20 are to form complex water seal 100 through sulfuration in the vulcanizer die cavity.
When making complex water seal 100 of the present utility model, at first kneading and on extruder extrusion molding water seal body 10, then kneading sheet 20.Then, water seal body 10 is put into the die cavity of vulcanizer and ajust, (the sheet size is by water seal product size or customer requirement for the sheet 20 that will cut again, general thickness is 2.2～2.5mm, length is any, width be 70～75mm) be laid in water seal body 10 in the die cavity of vulcanizer the surface and ajust, matched moulds production obtains complex water seal 100.The process that matched moulds production obtains complex water seal 100 belongs to the common processes of existing preparation rubber and plastic usually the people of knowledge in having this area, do not repeat them here.
In sum, the utility model is formed through sulfuration by sheet and rubber, and both intermiscibilities are good, forms a rubber and plastic complex, products obtained therefrom can be crooked arbitrarily, solved the expense of polytetrafluoroethylene (PTFE) complex water seal palpus with wooden-box package, transport cost also significantly reduces, and the friction factor of sheet is low, improved antiwear property, it is also more convenient to install, and this utility model water seal product also prolongs application life greatly, has improved the practicality of water seal product effectively.
Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
