Abstract
The utility model relates to a kind of flange sealer, particularly a kind of flange sealer with metallic packing.The maximum feature of the utility model be by rubber gasket (4) with metallic shim (3) sulfuration in order to integrative-structure, the rubber gasket (4) wherein having metallic shim (3) both sides after satellite hole (5) makes sulfuration on metallic shim (3) can realize at satellite hole (5) place connecting.This improvement efficiently solves, and prior art middle washer is easily twisted after installing, be squeezed uneven phenomenon, improves the reliability of sealing.
Description
Technical field
The utility model relates to a kind of flange sealer, particularly a kind of flange sealer with metallic packing.
Background technique
Conduit adopts flange sealing trough rubber sealing or rubber cushion sealing usually.Flange sealing trough rubber sealing is when mounted because the installment state of cushion rubber in seal groove cannot be seen, often there will be seal ring squeezed, cut, the phenomenon such as to turn round, install and temporarily not leak afterwards, under the operating modes such as pressure, vibration, fatigue As time goes on, the unsafe factor such as leakage of oil, gas leakage exposes gradually; Flange rubber cushion encapsulating method is difficult to control to seal rubber pad decrement, often there will be rubber cushion pressurized uneven, and local is damaged by pressure or seal rubber pad decrement causes the phenomenons such as leakage not.
Summary of the invention
Goal of the invention: the utility model provides the conduit flange seal connection that a kind of structure is simple, sealing reliability is high, effectively can solve traditional rubber cushion sealing means decrement and be difficult to control, relative movement, O-ring seal rubber cushion squeezes, cut, the problem such as to turn round, and improves sealing reliability.
The technical solution of the utility model is: this flange sealer comprises flange 1, seal washer and fixing bolt, it is characterized by: the metallic packing 2 that the seal washer between flange 1 is integrated;
Metallic packing 2 has bolt hole;
Metallic packing 2 is made up of metallic shim 3 and rubber seal 4;
Two end faces of metallic shim 3 are all fixed with rubber seal 4;
The rubber seal 4 metallic shim 3 had on the end face of 5, two, satellite hole is linked together by satellite hole 5;
Rubber seal 4 sulfuration on two end faces connects.
The utility model has the advantages of: the utility model is provided with metallic packing 2 between two flange 1 faying surfaces, metallic packing 2 has the bolt fixing hole mated with flange 1, can anti-sliding stop; Rubber seal 4 is connected by satellite hole 5 sulfuration on metallic shim 2, solve conventional seals cushion rubber pressurized uneven, easily squeezed, cut, the problem such as to turn round, can O-ring seal 4 decrement be controlled in optimum range, improve sealing reliability.
Accompanying drawing explanation
Fig. 1 is the utility model explosive view
Fig. 2 is metallic packing structural representation
Fig. 3 is metallic shim structural scheme of mechanism
In figure, 1 is flange, and 2 is metallic packing, and 3 is metallic shim, and 4 is rubber seal, and 5 is satellite hole.
Embodiment
A kind of fuel duct flange seal connection set, comprise flange 1, technology gasket seal 2 and fixing bolt, metallic packing 2 there is the bolt fixing hole mated with flange 1, during installation, two flanges 1 are bolted to connection with metallic packing 2, can effectively prevent metallic packing 2 from sliding; The tinsel 3 of metallic packing 2 is provided with satellite hole 5, and rubber seal 4 passes through satellite hole 5 sulfuration on two end faces of metallic shim 3.
This model utility, by arranging the bolt fixing hole mated with flange 1 on metallic packing 2, effectively can solve conventional seals pad relative flange plate 1 sliding problem; By arranging satellite hole 5 on metallic packing 2, rubber seal 4 is fixedly connected on two end faces of metallic shim 3 by vulcanization, solve conventional seals cushion rubber pressurized uneven, easily squeezed, cut, the problem such as to turn round, O-ring seal 4 decrement can be controlled, in optimum range, to improve sealing reliability.
