Embodiment Construction

[0011] The present invention includes a compensating ring seat 21, a spring 22, a ring sleeve 23, a seal ring 24, a friction ring 25, and an anti-rotation pin 26. The spring 22 is installed at the inner end of the ring cavity of the compensating ring seat 21. The front port of the seat 21 is fixedly connected by interference fit, the friction ring 25 is installed with the ring sleeve 23 through the sealing ring 24, the spring 22 acts on the inner end table surface 25' of the friction ring 25 and the inner end surface 23' of the ring sleeve 23, and the spring 22 pushes the friction ring 25 to move forward for compensation, the inner end surface 23' of the ring sleeve 23 makes the spring 22 stop, and an anti-rotation pin 26 is provided between the inner end of the friction ring 25 and the compensating ring seat 21 .

[0012] As shown in the structural embodiment of the upper part of the accompanying drawing 2, the spring 22 is a wave plate spring, and the front end surface of the...

Abstract

The invention relates to a compensation ring component for a spring mechanical seal device, comprising a compensation ring base (21), a spring (22), a loop (23), a sealing ring (24), a friction ring (25) and an anti rotation peg (26). The compensation ring component for a spring mechanical seal device has the advantages of simple and reasonable structure, reliable combination, smooth operation of the friction ring, safe and reliable operation, preventing pollution of the spring from medium, applicability to higher working condition and facility for transportation and installation thanks to an integrated structure.

Description

technical field [0001] The invention relates to a mechanical seal device, especially a compensating ring component of a spring mechanical seal device. Background technique [0002] The mechanical seal device is a sealing device that prevents the working fluid from leaking along the rotating shaft. The mechanical seal device is also called the end face seal device. It consists of a pair of moving ring and static ring perpendicular to the axis, and the moving ring (compensation ring) Under the action of the spring) mechanism, its end face and the end face of the static ring keep fit, slide and rotate. The moving ring is connected to the shaft transmission, and the static ring is connected to the end cover, and the sealing effect on the rotating shaft is completed through the relative sliding rotation of the moving ring and the static ring. [0003] The existing spring-type mechanical seal compensating ring assembly (see accompanying drawing 1) generally consists of a compensa...
