Abstract
The utility model discloses a double seal flange plate suitable for high pressure environment, which comprises a flange body and a rubber seal washer, wherein a cylindrical ring-shaped groove is arranged on a pipeline port which is arranged on the bottom portion of the flange body, the rubber seal washer comprises a seal washer and a ring-shaped seal cushion layer, the seal washer and the ring-shaped seal cushion layer are arranged integrally, and the ring-shaped seal cushion layer is embedded in the cylindrical ring-shaped groove. When two flange plate with the same structure are connected, the seal washer is close to the flange plates, the pressure of pipeline liquid enables the ring-shaped seal cushion layer to be stressed and to be close toward the cylindrical ring-shaped groove, and the flange plates achieve double seal anti-leakage high pressure resistance effect. The double seal flange plate suitable for the high pressure environment has the advantages that the double seal flange plate suitable for the high pressure environment reduces cost, is simple in structure, excellent in double seal anti-leakage effect, and is suitable for the high pressure environment.
Description
Technical field
The utility model relates to flange plate, is specifically related to a kind of hyperbaric environment double seal flange plate that is applicable to.
Background technique
At present, the modes such as immersion oil asbestos packing, asbestos wound gasket (metal gasket) are adopted in the pipeline flanges joint more, but the material of asbestos packing is easily cracked, and intermediate course is loose, Seepage more easily occurs in the medium that causes pipeline to be carried, and can only be used for the mesolow pipeline.The asbestos wound gasket is commonly called as metal gasket, although its sealing effect is better, pressure-bearing is higher, and cost is higher.
The model utility content
The purpose of this utility model provides a kind of flange plate that anti-leak result is good, be applicable to hyperbaric environment that seals.
The technical solution adopted in the utility model is:
A kind of hyperbaric environment double seal flange plate that is applicable to, flange plate comprises flange body and rubber gasket, described flange body lower tube road junction has the cylindrical annular groove.
Described rubber gasket is comprised of seal washer and ring packing bed course, and seal washer and ring packing bed course are all one, and the ring packing bed course embeds in the cylindrical annular groove.
When the flange plate of described two same structures connected, seal washer was close to flange plate, the pressure of pipeline fluid make the ring packing bed course stressed to the cylindrical annular groove near, thereby make flange plate reach the high voltage bearing effect of double seal anti-leak.
The utility model has the advantages that: simple in structure, reduce cost, the double seal anti-leak result is good, and is high pressure resistant.
Description of drawings
Fig. 1 is external structure schematic diagram of the present utility model.
Fig. 2 is complete section structural representation of the present utility model.
Wherein: 1. flange body, 2. seal washer, 3. cylindrical annular groove, 4. ring packing bed course, 5. pipeline.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model as shown in Figure 1 and Figure 2, a kind of hyperbaric environment double seal flange plate that is applicable to of the present utility model, comprise flange body 1 and rubber gasket, 5 mouthfuls of places of described flange body 1 bottom pipe have cylindrical annular groove 3, rubber gasket is comprised of seal washer 2 and ring packing bed course 4, and seal washer 2 and ring packing bed course 4 are with being integrated.
When [0013] flange plate of described two same structures connects, seal washer 2 is close to flange plate, ring packing bed course 4 embeds in the cylindrical annular groove 3, the pressure of pipeline 5 fluids make ring packing bed course 4 stressed to cylindrical annular groove 3 near, the pressure of fluid is stronger, annular seal packing ring 4 stress deformations are larger to the extruding force of cylinder shape groove 3, make sealing effect better, thereby make flange plate reach the high voltage bearing effect of double seal anti-leak, simple in structure, so that flange plate reduces cost, be applicable to hyperbaric environment.
Claims (2)
1. one kind is applicable to hyperbaric environment double seal flange plate, flange plate is comprised of flange body (1) and rubber gasket, it is characterized in that: described flange body (1) bottom pipe (a 5) mouthful place has cylindrical annular groove (3), and described rubber gasket is comprised of seal washer (2) and ring packing bed course (4).
2. described a kind of hyperbaric environment double seal flange plate that is applicable to according to claim 1, it is characterized in that: described seal washer (2) and ring packing bed course (4) are with being integrated, seal washer (2) is close to flange plate, and ring packing bed course (4) embeds in the cylindrical annular groove (3).
