Background
A Flange (Flange), also known as a Flange collar or Flange. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flanges are used in pairs, the low-pressure pipeline can be screwed with the flanges, and the flanges are welded under the pressure of more than four kilograms. And a sealing gasket is arranged between the two flanges and then is fastened by bolts. The flanges of different pressures have different thicknesses and they use different bolts. When the water pump and the valve are connected with a pipeline, the parts of the equipment and equipment are also made into corresponding flange shapes, which are also called flange connection. The connecting parts which are connected by using bolts at the peripheries of two planes and are closed at the same time are generally called flanges, and for example, the connecting parts of the ventilating duct can be called flange parts.
Among the prior art, when the GIS pipe connection among the high-voltage apparatus, need use the ring flange to connect, because the electrical components who places in the GIS pipeline need fill insulating gas and protect, consequently, propose the requirement to the sealed of ring flange, current flange is sealed to carry out the pressfitting through sealed the pad, but, long-time operation to and dismantle in the maintenance process, can't avoid causing the wearing and tearing of packing ring. Cause and produce the clearance between packing ring and the seal groove, cause the influence to sealed, however, this kind of slight clearance can't discover again, and then can cause the influence to sealed, for this reason, needs a sealed effectual flange.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a novel flange for a power station, which can solve the technical problem in the background technology.
The utility model is realized by adopting the following technical scheme: a flange for a power station comprises a flange plate body, wherein four external lugs are arranged on the flange plate, the external lugs and the flange plate are integrally cast, and the external lugs are arc blocks protruding out of the outer edge of the flange plate;
the flange plate is also provided with a sealing groove, a sealing gasket is clamped in the sealing groove, the sealing groove is a rectangular groove, the sealing gasket is a cuboid, a rubber ring is coated on the upper portion of the sealing gasket, gas is filled in the rubber ring, the top of the rubber ring is provided with a gland, the size of the gland is larger than that of the sealing gasket, the size of the gland is the same as that of the sealing groove, and the height of the sealing gasket is slightly higher than the depth of the sealing groove;
the inner wall of the flange plate is provided with a lining groove and a lining hole, the lining groove and the lining hole are used for fixing the lining sleeve, the lining groove is formed downwards from the surface of the flange plate, and the depth of the lining groove is less than half of the height of the flange plate;
the lining hole is formed inwards in the middle of the inner wall of the flange plate and is a blind hole.
Preferably, the flange plate is provided with heat dissipation holes which are uniformly distributed.
Preferably, the line connecting the lining groove and the lining hole passes through the circle center of the flange plate.
Preferably, the inner wall of the flange plate is provided with a lining plate, and the lining plate is a circular ring plate and is arranged close to the edge of the flange plate.
Compared with the prior art, the flange sealing structure has the advantages that the sealing of the flange is improved, the abrasion caused by hard connection of the original sealing gasket is changed, and the sealing effect is stronger.
Drawings
FIG. 1 is a schematic diagram of the apparatus of the present invention;
fig. 2 is a sectional view taken along line a-a in fig. 1.
In the figure: 1. a flange plate; 11. an outer ear; 111. mounting holes; 2. heat dissipation holes; 3. a sealing groove; 4. a lining hole; 5. a lining groove; 6. a liner plate; 7. a gasket; 71. a rubber ring; 72. and (7) pressing the cover.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
The utility model is further explained with reference to the accompanying drawings, and as shown in fig. 1 and fig. 2, the flange for the power station comprises a flange plate 1 body, four outer lugs 11 are arranged on the flange plate 1, the outer lugs 11 and the flange plate 1 are integrally cast, and the outer lugs 11 are arc blocks protruding out of the outer edge of the flange plate 1;
