Problems solved by technology

However, in this case, there are problems in that the sealing performance is lowered at the cut portion, and since the cut surface tends to deviate, it is difficult to perform butting in a centered manner, resulting in poor operability.
[0009] Figure 7 And the seal shown in 8 does not produce eccentricity at the cut-off part, but there is a problem that temporary fixation is difficult because the seal does not hang in the axial direction, and the operability is significantly reduced.
In addition, there is also the problem that it is not easy to process

Embodiment Construction

[0039] The method for implementing the extrusion seal related to the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, as long as it does not depart from the scope of the present invention, various modifications can be made based on the knowledge of those skilled in the art. Changes, Corrections and Improvements.

[0040] figure 1 An example in which the present invention is applied to a typical O-ring in a squeeze seal is shown, and a case where the O-ring is applied to a mechanical seal device will be described. figure 1 (a) is the main sectional view, figure 1 (b) is a perspective view of an O-ring.

[0041] figure 1 The mechanical seal device shown has a contact mechanical seal structure. In this contact mechanical seal structure, the stationary side sealing unit 12 and the rotating side sealing unit 13 are inserted in the sealing cover 10 and through the sealing cover 10 in a...

Abstract

Provided is a squeeze gasket which has a three-dimensional-curved-surface-shaped cut surface, and which, during installation in a device, does not require the use of an adhesive agent, can be temporarily installed in an easy way, and can be brought into close contact with mating parts with a high accuracy. Said squeeze gasket is characterized in that at least at one arbitrary place in an endless ring which is finished to predetermined dimensions, the squeeze gasket has a three-dimensional-curved-surface-shaped cut surface which extends obliquely at a predetermined angle of ? with respect to the radial direction of the ring, which is approximately S-shaped in a side view, and which is bent in the width direction.

Description

technical field [0001] The invention relates to an extruded seal, which is used for mechanical seals of pumps, mixers and other industrial machinery, or other seals. Background technique [0002] In the mechanical seals of general industrial machinery such as pumps and mixers, split-type parts that divide the sliding seal ring into two halves are used. The O-ring-shaped extrusion seal used for the part must have at least one Cut off. [0003] In addition, due to deterioration due to long-term use, etc., it is sometimes necessary to replace the O-ring squeeze seal, but the O-ring squeeze seal has an endless ring shape, so it is necessary to disassemble the main body of the device when installing it. . Therefore, there is proposed an O-ring-shaped extrusion packing in which one position in the circumferential direction is cut off. However, in this case, there are problems in that the sealing performance is lowered at the cut portion, and since the cut surface tends to devia...
