Problems solved by technology

Due to problems such as different pipe diameters, different centers, and different axes, there must be gaps when plugging in, resulting in leakage.
Most of the current seals use sealing rings, but they cannot solve the problem of serious misalignment and misalignment.

Embodiment 1

[0009] The working principle of embodiment 1 mechanism:

[0010] The mechanism moves with the compression and reset of the end face sealing flange.

[0011] When starting to compress and enter the pipeline: the tie rod Ⅰ (4) pushes the small diameter connecting shaft (7) to drive the small roller (6) to rotate to the minimum stroke position, at this time the connecting shaft (7) drives the tie rod Ⅱ (8) to the end face fixed flange Movement in the direction of Ⅰ(1) drives the sealing plate (11) to fall. At this time, all parts of the mechanism are at the lowest position, so as to smoothly enter the casing without resistance or rubbing.

[0012] When compressed in place: the tie rod Ⅰ (4) pushes the small diameter connecting shaft (7) to drive the small roller (6) to rotate to the maximum stroke position, at this time the connecting shaft (7) drives the tie rod Ⅱ (8) to the fixed flange Ⅲ (12) ) Moves in the direction to drive the sealing plate (11) to push up. At this time, all par...

Embodiment 2

[0013] Embodiment 2 The connection relationship of each component:

[0014] One end of the tie rod Ⅰ (4) is welded to the movable flange Ⅱ (3), and the other end is welded to the small roller connecting plate (6); the small roller (5) is installed outside the small diameter connecting shaft (7), on the tie rod Ⅰ (4) It rolls under the push of the compression spring (2), and its stroke is compressed by the compression spring (2); the small roller connecting plate (6) is welded on the outside of the small diameter connecting shaft (7), and is connected with the tie rod II (8) through a small diameter The rotating shaft (7) is connected; one end of the tie rod Ⅱ (8) is connected to the small roller connecting plate (6) through the small diameter connecting shaft (7), and the other end is welded to the sealing plate (11); the rotating shaft (10) passes through the rotating shaft casing ( 9); The sealing plate (11) passes through the sleeve (9) of the rotating shaft and is fixed by we...

Embodiment 3

[0015] Example 3 Key control data:

[0016] 1. The stroke of the small roller is the stroke of the end flange compression:

[0017] 2. The sealing plate can be multiple or two pieces, which can be made according to site needs, and the tie rod mechanism will be changed accordingly.

Abstract

The invention relates to a connecting rod sealing mechanism, in particular to a sealing mechanism suitable for plug-in of movable bushings, and belongs to the sealing technical field. The connecting rod sealing mechanism comprises a fixed flange I 1, a compression spring 2, a movable flange II 3, a pull rod I 4, a small roller 5, a small roller connecting plate 6, a small diameter connecting rotating shaft 7, a pull rod II 8, a rotating shaft cover 9, a rotating shaft 10, a sealing plate 11, a fixed flange III 12 and a small roller baffle plate 13, wherein the sealing mechanism is a four-bar mechanism, and is reversely acted along with the compression and reset of an end surface sealing flange. The connecting rod sealing mechanism solves the sealing problem when the decentraction and disalignment conditions are severer in the plug-in operation of pipes with different diameters; and sealing parts all adopt carbon steel or stainless steel materials, so that the benefits of practicability, high-temperature resistance and difficult deformation are achieved.

Description

Technical field [0001] The invention relates to a connecting rod sealing mechanism, in particular to a sealing mechanism for an opposite insertion of a movable sleeve, and belongs to the technical field of sealing. Background technique [0002] In many occasions in the chemical and metallurgical industries, pipelines of different diameters are inserted into each other for operation, such as: conveying slurry and powder into tanks, towers and other containers. Due to the problems of different pipe diameters, different concentricity, different shafts, etc., there must be a gap when inserting, causing leakage. Most of the current seals use sealing rings, but they cannot solve the problem of sealing under the conditions of misalignment and different shafts. Summary of the invention [0003] The problem to be solved by the present invention is to provide a connecting rod sealing mechanism, which overcomes the shortcomings of the above technology and solves the sealing problem under th...
