Stationary ring compensation assembly of mechanical sealing device

Abstract

A stationary ring compensation assembly of a mechanical sealing device is composed of a stationary ring (1), a stationary ring base (2), a compensation spring (3), an anti-rotation screw (4), an O-type sealing ring (5) and a gland (6); the rear end of the stationary ring base (2) is matched with a center hole seam allowance of the gland (6) in a sliding mode, the front end portion of the stationary ring base (2) is provided with an outer edge plate (24), a cylindrical rod part (41) of the anti-rotation screw (4) is matched with an anti-rotation screw mounting hole (25) on the outer edge plate(24) of the stationary ring base in a sliding mode, the anti-rotation screw (4) is fixedly connected with the inner side end face of the gland (6), and the stationary ring base (2) and the gland (6) form axial sliding and limiting fit connection; and the compensation spring (3) is inserted into a spring mounting base hole (64) in an inner side end face (61) of the gland (6) to thrust to act on theside end face of the outer edge plate (24) of the stationary ring base (2). A stationary ring compensation element is integrated on the gland (6), transportation, mounting and use are convenient, theaxial size is short, the structure is simple, the number of composition parts is small, the manufacturing cost is low, and the stationary ring compensation assembly of the mechanical sealing device can meet the mounting use of horizontal and vertical modes.

Description

technical field [0001] The invention relates to a static ring compensating assembly of a spring type mechanical seal device. Background technique [0002] For the static ring compensation assembly of the prior art spring type mechanical seal device, see the attached figure 1 As shown, it includes static ring, static ring seat, push ring, compensation spring, anti-rotation pin, O-ring; the static ring seat fits with the gland seam and is fixed by fastening screws; At the front end of the seat, spring mounting holes are evenly distributed on the circumference of the static ring seat, and a push ring is set between the rear end of the static ring and the static ring seat. The compensation spring is installed in the spring mounting hole on the static ring seat for thrust to push the ring. The push ring acts on the static ring to perform elastic compensation for axial movement to ensure that the end face of the static ring and the end face of the moving ring are always attached....

AI Technical Summary

Problems solved by technology

[0003] The static ring compensation assembly of the above-mentioned prior art has relatively long axial dimension, complex structure, many components, and high manufacturing cost, and the various components of the static ring assembly cannot be integrated, and it is only suitable for horizontal installation and use, not for vertical installation.
