Abstract
The invention discloses an accumulation blocking preventing structure of a mechanical sealing floating type stationary seal ring. The accumulation blocking preventing structure comprises a stationary assembly, a floating type stationary seal ring body, an elastic component and an auxiliary sealing piece. An annular cavity is formed among the stationary assembly, the floating type stationary seal ring body and the auxiliary sealing piece, and an opening of the annular cavity is far away from the elastic component. According to the accumulation blocking preventing structure, accumulations between the medium side stationary seal ring and a shell can be effectively prevented from being generated.
Description
Technical field
The present invention relates to a kind of mechanically-sealing apparatus, particularly relate to a kind of mechanical seal float type stationary ring and prevent gathering choke structure.
Background technology
Existing mechanical seal float type stationary ring is as shown in Figure 1, contact with auxiliary seal outside stationary ring, inner side contacts with auxiliary seal and back contacts with auxiliary seal, when outside contacts with auxiliary seal, adopt groove type structures, this structure gap between side medium stationary ring and housing is little, when dielectric viscosity crystallization high, easy contains granule, then easily produce to pile up (time serious, pile up and solidify), so that stationary ring flying ability decline or stuck, cause seal face because of cannot effective compensation and lost efficacy.
Summary of the invention
It is desirable to provide a kind of mechanical seal float type stationary ring is anti-gathers choke structure, it is possible to effectively prevent the generation of deposit between side medium stationary ring and housing.
For reaching above-mentioned purpose, the technical solution used in the present invention is as follows:
Mechanical seal float type stationary ring disclosed by the invention is anti-gathers choke structure, including quiet assembly, float type stationary ring, elastomeric element and auxiliary sealing member, being provided with annular chamber between described quiet assembly, float type stationary ring, auxiliary sealing member, the opening of described annular chamber is away from elastomeric element.
During use, fluid forms eddy current under pressure when flowing through opening in annular chamber, it is prevented that or the probability of minimizing particle packing, thus improving sealing property.
Preferably, the opening of described annular chamber is uncovered.
Further, described quiet assembly is provided with high pressure fluid channel, and described high pressure fluid channel connects with annular chamber.Can directly apply high-pressure fluid by high pressure fluid channel in annular chamber, form eddy current.
Preferred as one, described high pressure fluid channel is high pressure fluid channel A, and a port of described high pressure fluid channel A is positioned at the inwall of annular chamber.
Preferred as another kind, described high pressure fluid channel is high pressure fluid channel B, and the radial direction of the axial direction of described high pressure fluid channel B and annular chamber forms angle, and the opening of described annular chamber is positioned on the axis of high pressure fluid channel B.
The beneficial effects of the present invention is: solve for a long time due to granule materials, deposition cure, block a difficult problem for the mechanical seal premature failure caused of waiting indefinitely.
