Description
Technical field
The invention belongs to mechanical encapsulation devices technical field, specifically a kind of anti-mechanical water seal of overvoltage.
Background technology
Mechanical water seal is common mechanical encapsulation devices, the axial workpiece particularly rotated for needs.Mechanical water is enclosed in
During installation, axis and hole close installation that water seal inner and outer wall seals respectively with needs, water seal inner spring compression make to make pottery in water seal
Ceramic ring and graphite annulus are simultaneously tight, when shaft rotation is moved, ceramic ring and graphite annulus relative motion, but since ceramic ring and graphite annulus contact are tight
It is close, it can still play sealing function.
It in mechanical water seal installation process, needs water seal and part compression fit using press, during actual installation, easily
Excessive pressure is matched, and water seal inner spring is and tight, but press is also applying pressure to water seal, leads to ceramic ring and graphite annulus fragmentation,
The destruction that can not be retrieved is caused to water seal, therefore, factory generally requires to be fabricated separately tooling and installed for water seal, but the production produced
Product are different, need to make different toolings, make installation steps cumbersome, and tooling is expensive, with high costs.
Invention content
Goal of the invention：The deficiency that the purpose of the present invention is be directed in current technology provides a kind of mechanical water seal of anti-overvoltage, this
Body has the function of to prevent overvoltage, can not use tooling when mounted, reduce installation steps, greatly save cost.
Technical solution：To achieve the above object, the present invention provides a kind of mechanical water seal of anti-overvoltage, including 1 He of the first axle sleeve
Second axle sleeve 2,1 and second axle sleeve 2 of the first axle sleeve are the reeded cyclic structure of tool, are set in first axle sleeve 1
There is the first sealing ring 3, first sealing ring 3 is connect with the first axle sleeve 1 by support ring 5, and spring 6 is cased with outside support ring 5,
The second sealing ring 4 is provided in second axle sleeve 2, second sealing ring 4 is provided with cushion pad 7, institute between the second axle sleeve 2
2 inner wall of the second axle sleeve and feature contacts are stated, inner wall edge is provided with the larger guide ring 9 of internal diameter, 9 and first axle sleeve of guide ring
1 inner wall contacts, and plays guiding role in the mechanical water seal installation process, 1 inner wall of the first axle sleeve sets restraining position ring block
8,8 internal diameter of spacing ring is more than 9 internal diameter of guide ring, less than the internal diameter of the second axle sleeve 2 and the inner wall of feature contacts.
Preferably, when the spacing ring 8 is contacted with guide ring 9, spring 6 is not at and tight state.
Preferably, 3 material of the first sealing ring is ceramics.
Preferably, 4 material of the second sealing ring is graphite.
Preferably, the support ring 5 and 7 material of cushion pad are rubber.
Advantageous effect：The mechanical water seal of the anti-overvoltage of one kind of the present invention, 1 inner wall of the first axle sleeve setting restraining position ring block 8,
When spacing ring 8 is contacted with 2 upper limit ring 9 of the second axle sleeve, spring 6 is not at and tight state, can prevent excessive pressure during installation from matching, bullet
Spring 6 is simultaneously tight, and press continues to press to the first sealing ring 3 and the second sealing ring 4, leads to the first sealing ring 3 and the second sealing ring 4
Fragmentation.
The anti-over-pressed mechanical water encapsulation timing can not separately match tooling, make installation more easy, substantially reduce cost, together
When can prevent mechanical water seal excessive pressure damages.
