Problems solved by technology

[0002] At present, the sealing structure of the connecting flange used on the heavy-duty hydraulic press adopts rubber seal, but in the use of the 10,000-ton oil cylinder, due to the large diameter and high pressure of the connecting flange, under the action of ultra-high pressure, the deformation of the connecting flange is large, and the law cannot be used. The deformation of the flange connection exceeds the compression deformation range of the rubber seal, resulting in serious oil leakage and cannot be used normally

Embodiment Construction

[0013] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a flange 1 and a joint body 2. The sealing edge of the joint body 2 is pressed against the flange 1 with a metal taper 3, and the flange 1 is equipped with a connecting screw 4; the metal taper 3 is bidirectional. tapered surface.

[0014] As shown in the figure: the metal cone gasket 3 is designed as a two-way cone surface, and the sealing edge of the cone surface and the joint body 2 is pressed against the flange plate 1, and the metal seal can be realized by continuously tightening the connecting screw 4. When oil leakage occurs, the oil leakage phenomenon can be eliminated by tightening the connecting screw 4 again.

[0015] This product connects the flange plate 1 by the connecting screw 4, and it is enough to press the joint body 2 and the metal cone washer 3. In particular, the coaxiality between the metal cone washer 3 and the joint body 2 must be strictly r...

Abstract

The invention discloses a flange structure, and particularly discloses a large-sized superhigh pressure connecting flange structure in a 10 thousand ton class large-sized hydraulic press piston structure. The large-sized superhigh pressure attachment flange structure comprises a flange and a connector body. The large-sized superhigh pressure connecting flange structure is characterized in that a metal conical pad is pressed on the sealed edge of the connector body, which is near to the flange; and connecting screws are installed on the flange. The large-sized superhigh pressure connecting flange structure is strictly sealed by depending on the metal deformation between the metal conical pad and the flange and under the action of a large pull force of high-strength screw bolts, and has good use effect on a large-bore pipeline. The invention has good sealing effect under the condition of guaranteeing the superhigh pressure state of superhigh pressure oil, reliable use and long service life, and is used in a 10 thousand ton class large-sized hydraulic press piston structure with 100MPa hydraulic pressure.

Description

(1) Technical field [0001] The invention relates to a flange structure, in particular to a large ultra-high pressure connecting flange structure in the piston structure of a 10,000-ton large hydraulic press. (2) Background technology [0002] At present, the sealing structure of the connecting flange used on the heavy-duty hydraulic press adopts a rubber seal, but in the use of the 10,000-ton oil cylinder, due to the large diameter of the connecting flange and the high pressure, the deformation of the connecting flange is large under the action of ultra-high pressure. The deformation of the flange connection exceeds the compression deformation range of the rubber seal, resulting in serious oil leakage and cannot be used normally. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a large ultra-high pressure connection flange structure with good sealing effect and reliable performance. [0004] T...
