Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] The present invention is a sealing spherical flange structure tooling with a sealing groove structure, the structure is as follows figure 1 As shown, it includes a concave spherical flange 3 and a convex spherical flange 2 that are connected in an anastomotic manner. There is also a sealing groove 5 on the connecting surface of the convex spherical flange 2 and the concave spherical flange 3. The sealing groove 5 adopts a lathe processing method, such as figure 2 As shown, there is an O-ring 6 built into the sealing groove 5, wherein the O-ring 6 is a standard part, and a nut 4 runs through the edge of the concave spherical flange 3 and the convex spherical flange 2, and is fastened by a bolt 1, wherein , the concave spherical flange 3 and the convex spherical flange 2 are large-diameter spherical surfaces, and the spherical radii are...

Abstract

The invention discloses a sealing sphere flange structure tool provided with a sealing groove structure. The sealing sphere flange structure tool comprises a concave sphere flange and a convex sphere flange which are connected in an engaging way; a connecting surface of the convex sphere flange and the concave sphere flange is also provided with a sealing groove; an O-shaped ring is arranged inside the sealing groove; the edges of the concave sphere flange and the convex sphere flange are also communicated with nuts and are fastened by bolts; the concave sphere flange and the convex sphere flange are both large-diameter spheres and are the same in sphere radius. The sealing sphere flange structure tool disclosed by the invention is capable of solving the problem of leakage, caused by difference of installation position and difference of the tightening torque of each bolt, of a flange sealing structure in the prior art.

Description

technical field [0001] The invention belongs to the technical field of sealing structures, and in particular relates to a sealing spherical flange structure tooling with a sealing groove structure. Background technique [0002] At present, in general flange seals, the most common flange seal forms are concave-convex flanges, flat convex flanges, and tongue-and-groove flanges. When the bolts are fastened, if the bolts are unevenly stressed, It is very likely to cause leakage, especially in the case of large diameter and large number of bolts. For the flange seal with a small diameter, if the tightening torque is large, it is very easy to crush the gasket or sealing ring, resulting in pressure leakage and pressure relief. Contents of the invention [0003] The purpose of the present invention is to provide a sealing spherical flange structure tooling with a sealing groove structure, which solves the problem of leakage caused by the flange sealing structure in the prior art ...
