Abstract
The utility model discloses a flange structure, in particular to a large-scale super high pressure connecting flange structure in the piston structure of a 10,000-ton large-scale hydraulic press. The flange structure comprises a ring flange and a connector body, and is characterized in that a metal conical gasket is compressed on the sealed cutting edge of the connector body through the ring flange, and connecting screws are mounted on the ring flange. The metal deformation between the metal conical gasket and the ring flange results in the strict sealing of the utility model under the action of big tension of high-strength bolts, and the structure has an excellent use effect on pipelines with large drift diameters. The utility model can guarantee the excellent sealing effect of the super high pressure oil in the super high pressure state, and has the advantages of reliable use and long service life. The utility model is used in the piston structural design of the 10,000-ton large-scale hydraulic press with liquid pressure amounting to 100 Mpa.
Description
(1) technical field
The utility model relates to a kind of flange arrangement, the large-sized ultra-high pressure connecting flange structure in particularly a kind of ton large hydraulic press piston structure.
(2) background technique
At present, the adpting flange sealing configuration that uses on heavy hydraulic press all adopts rubber seal, but in the ton oil cylinder uses, because the big pressure height of adpting flange latus rectum, under the ultrahigh pressure effect, the adpting flange distortion is big, and flange connects amount of deformation and exceeds the compressive strain scope of rubber seal, cause leakage of oil serious, can't normally use.
(3) summary of the invention
The utility model provides the large-sized ultra-high pressure connecting flange structure of a kind of good sealing effect, reliable performance in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of large-sized ultra-high pressure connecting flange structure comprises flange plate and fittings body, and its special way is: described fittings body sealing cutting edge place has compressed metal awl pad by flange plate, and attachment screw is installed on the flange plate.
Large-sized ultra-high pressure connecting flange structure of the present utility model, it further improves and is: described metal awl pad is the two-way conical surface.
The utility model has solved super large latus rectum hydraulic tubing and has connected the sealing leakage of oil at ultrahigh pressure state lower flange, can't normally use problem.
The utility model fills up sealing configuration with big latus rectum ultra-high pressure connecting flange invention for adopting the metal awl, rely on the flow of metal between metal awl pad and the flange plate, strict seal under the big tension of high-strength bolt, the sealing surface distortion may appear after a period of time of working under the ultrahigh pressure state and seepage, only need this moment get final product tightening screw, this structure using effect on latus rectum pipeline greatly is very good.The utility model guarantees that super high pressure oil has good sealing effect at the ultrahigh pressure state; Use reliably, the life-span is long.The utility model uses in the ton large hydraulic press piston structure design of fluid pressure as 100Mpa.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks generalized section for master of the present utility model;
Fig. 2 looks schematic representation for a left side of the present utility model.
Among the figure, 1 flange plate, 2 fittings bodies, 3 metals awl pad, 4 attachment screws.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises flange plate 1 and fittings body 2, and fittings body 2 sealing cutting edge places have compressed metal awl pad 3 by flange plate 1, and attachment screw 4 is installed on the flange plate 1; Metal awl pad 3 is the two-way conical surface.
As shown in the figure: metal awl pad 3 is designed to the two-way conical surface, and this conical surface and fittings body 2 sealing cutting edges compress by flange plate 1, tighten attachment screw 4 continuously and can realize metallic seal.When leakage of oil occurring, tighten attachment screw 4 once more and can eliminate oil leakage phenomenon.
This product is by attachment screw 4 mounting flanges 1, and pressed joint body 2 and metal awl pad 3 get final product, and what particularly point out is that metal awl pad 3 must be strict with the coaxality of fittings body 2, guarantees that the connecting body cutting edge is axially vertical with metal awl pad 3.After this structure was used, ultrahigh pressure state lower seal is effective, and was easy to maintenance, and the life-span is long.
Claims (2)
1. a large-sized ultra-high pressure connecting flange structure comprises flange plate (1) and fittings body (2), it is characterized in that: described fittings body (2) sealing cutting edge place has compressed metal awl pad (3) by flange plate (1), and attachment screw (4) is installed on the flange plate (1).
2. large-sized ultra-high pressure connecting flange structure according to claim 1 is characterized in that: described metal awl pad (3) is the two-way conical surface.
