Abstract
The invention relates to a bellows mechanical seal device which comprises a movable ring (1), a shaft sleeve (2), a static ring (3), a press cover (4), a cooling sleeve (5) and sealing gaskets (6,7), wherein a sharp quenching hole (41) is drilled on the press cover (4). The invention is characterized in that the size of the sealing gasket (6) is the same as that of the gasket (7), and a groove (8) is distributed on the inner bore annular surface of the sealing gaskets (6,7). Both of the gaskets (6, 7) have universality, the groove (8) on the gaskets (6, 7) can ensure the effective gap between the sealing gaskets and the cooling sleeve (5), and thereby ensuring the circulation of cooling liquid. The problem of erroneous installation cannot occur, and the invention can be conveniently maintained and replaced.
Description
Technical field
What the present invention relates to is mechanical seal device, and particularly the gasket structure to mechanical seal device for rubber bellows improves.
Background technique
Mechanical seal device is a kind of seal arrangement that prevents that working fluid from leaking along running shaft, mechanical seal device claims face seals again, by a pair of rotating ring and stationary ring perpendicular to axis, and compensated loop (rotating ring or stationary ring) its end face and uncompensated ring end face keep the applying slip formation that is rotatably assorted down in elastic compensating (bellows) mechanism effect.Rotating ring is connected with shaft drive, and stationary ring is connected with end cap, pays the slide relative rotation by rotating ring and stationary ring friction and finishes the rotation axis seal effect.
The prior art mechanical seal device for rubber bellows, particularly DM series mechanical seal device for rubber bellows is referring to shown in the accompanying drawing 1, include rotating ring 1, axle sleeve 2 is a rotating seat, stationary ring 3 (assembly), gland 4, coolant jacket 5, rotating ring 1 cooperates by gasket seal 6 and screw with seam 2a on the axle sleeve 2 and is sealedly and fixedly connected, promptly on being connected face, the seam 2a on rotating ring 1 and the axle sleeve 2 is provided with gasket seal 6, seam 3a on stationary ring 3 (assembly) and the gland 4 cooperates and is connected with screw by gasket seal 7, promptly on being connected face, the seam 3a on stationary ring 3 (assembly) and the gland 4 is provided with gasket seal 7, coolant jacket 5 is fixedlyed connected with gland 4, on gland 4, offer chilling hole 41 input cooling mediums, the cooling medium that coolant jacket 4 is imported chilling hole 41 carries out baffling and is incorporated into dynamic and static ring frictional fit end, to frictional fit end and compensated loop (stationary ring) compensating element---and the heat that bellows 32 produces dispels the heat cold.
Ring places in the gasket seal 7 that the cooling medium of above-mentioned prior art chilling hole 41 input will be provided with through stationary ring and gland seam fitting surface, promptly ring and 5 of coolant jackets will guarantee design gaps in the pad 7, with assurance cooling medium unobstructed flow mistake.Because the gasket seal 6 that rotating ring 1 and axle sleeve 2 seam 2a fitting surfaces are provided with reaches approximate with the size shape of the gasket seal 7 that stationary ring 3 (assembly) and gland 4 seam 3a fitting surfaces are provided with, be not easily distinguishable during assembling, often be easy to dress mistake mutually when particularly maintenance is assembled.Because gasket seal 6 internal orifice dimensions are less than gasket seal 7, once misloading then causes the interval of 5 of gasket seal 7 and coolant jackets very little, seriously block cooling medium and flow through, cause the mechanical seal device damage; In the time of simultaneously on the seam 2a fitting surface of gasket seal 7 misloadings that endoporus is bigger on rotating ring 1 and axle sleeve 2, centralized positioning is bad, and it is big that interior czermak space becomes, and also is easy to generate leakage.The prior art gasket seal 6,7 does not have versatility, need produce to be equipped with two kinds of pads, and also nature can produce and produce and the operating cost increase, uses maintenance inconvenient.
Summary of the invention
The objective of the invention is to improve at above-mentioned prior art problem, a kind of maintenance assembling of being convenient to is provided, can fully guarantee the mechanical seal device for rubber bellows that coolant guiding channel is unimpeded, particularly it has the gasket seal of versatility.
Technical solution of the present invention is with installation gasket seal 6, the 7 unified specification size shapes of dynamic and static ring, is distributed on the endoporus anchor ring of gasket seal 6,7 and is provided with groove 8.
The present invention is with gasket seal 6, the 7 unified specification size shapes of dynamic and static ring, because the endoporus of gasket seal 6,7 has had unified size shape, two pads not only have versatility, and be distributed the groove 8 that is provided with on the endoporus anchor ring of gasket seal 6,7 and can ensure fully that 5 of gasket seal and coolant jackets form effective gaps, the problem that mistake is assembled can not appear in the circulation of assurance cooling liquid; The endoporus of gasket seal 6,7 is that multi-point partial supports the centering mode, also can guarantee the coaxality and the sealing of rotating ring gasket seal 6 assemblings.Produce a kind of gasket seals as 6,7 needs of the gasket seal of easily damaged parts and get final product, produce easy, convenient maintenance and replacement.

Embodiment
The present invention includes rotating ring 1, axle sleeve 2 is rotating seat, stationary ring 3 (assembly), gland 4, coolant jacket 5, rotating ring 1 cooperates by gasket seal 6 and screw with seam 2a on the axle sleeve 2 and is sealedly and fixedly connected, seam 3a on stationary ring 3 (assembly) and the gland 4 cooperates and is connected with screw by gasket seal 7, coolant jacket 5 is fixedlyed connected with gland 4, on gland 4, offer chilling hole 41, sealing gasket 6 is identical with sealing gasket 7 geomeries, is distributed on the endoporus anchor ring of gasket seal 6,7 and is provided with groove 8.The groove 8 that distribution is offered on the gasket seal 6/7 endoporus anchor ring can guarantee when assembling and 5 of coolant jackets formed chute, guarantees the cooling liquid circulation; Flange 81 when gasket seal 6/7 is the rotating seat assembling with axle sleeve 2 on its endoporus anchor ring can be guaranteed concentric locating, does not produce skew, guarantees the pressure bearing and seal ability.
Shown in accompanying drawing 1 embodiment, stationary ring is a compensated loop, and stationary ring 3 is made of static friction ring 31, bellows 32, tailstock 33, and the seam 3a on the tailstock 33 of stationary ring 3 and the gland 4 cooperates and is connected with screw by gasket seal 7.Certainly also rotating ring of compensated loop promptly is provided with connection compensating element---bellows on rotating ring.
