Abstract
The invention discloses a mechanical seal device for a compact corrugated pipe, which comprises a stationary ring, a movable ring, an installing shaft sleeve; a connecting ring sleeve (41) is arranged on the lower part of a tailstock (4) serving as a corrugated pipe compensation ring component of the movable ring; the connecting ring sleeve (41) is provided with an anti-rotation block bin (42) which is matched with an L-shaped blocking groove (52) arranged at the external end part of a shaft sleeve (5) and is connected with the tailstock (4) in a blocking and fixing way so as to reduce the volume of the whole axial size of the corrugated pipe mechanical seal; and therefore, the mechanical seal device for a compact corrugated pipe can be arranged in a narrow device space to be used, is very convenient and fast to install, and saves time and labor.
Description
Technical field
What the present invention relates to is mechanical seal device.
Background technique
Existing common mechanical seal device for rubber bellows, include stationary ring and rotating ring, bellows compensated ring component as rotating ring includes friction ring, the friction ring seat, bellows, tailstock constitutes, friction ring is inlaid on the friction ring seat, the rear and front end of bellows is welded to connect with friction ring seat and tailstock respectively, offer auxiliary seal ring and the fastening screw trip bolt that is connected with axle sleeve at tailstock, the bellows compensated ring component is fixedlyed connected installation with axle sleeve, because the bellows compensated loop is to fixedly connected with axle sleeve with fastening screw trip bolt by the tailstock that the bellows rear end connects, namely because the bellows component afterbody is provided with Cock screw, cause the axial volume of bellows component to increase, when installing space is narrow and small, this common bellows mechanical seal can't be installed and used owing to be subjected to the axial dimension volume restrictions.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art and improve, a kind of axial dimension is provided
Compact mechanical seal device for rubber bellows,Being applicable to that narrow and small seal space installs and uses, and easy for installation.
The present invention includes stationary ring, rotating ring, axle sleeve is installed, gland, as the bellows compensated ring component of rotating ring by friction ring 1, friction ring seat 2, bellows 3, tailstock 4 constitutes, friction ring 1 is inlaid on the friction ring seat 2, the rear and front end of bellows 3 is welded to connect with friction ring seat 2 and tailstock 4 respectively, inner ring surface at gland offers the seam groove, outer ring surface at stationary ring has the seam groove, the seam groove of offering on stationary ring and the gland inner ring surface cooperates installation, seam groove on the stationary ring outer ring surface is equipped with O-ring seals, form the seal ring sealing between stationary ring and gland, it is characterized in that offering connection ring set 41 at (under the inner ring surface of bellows 3) on the tailstock 4, be fixed with anti-rotation bayonet lock 42 at connection ring set 41, in axle sleeve 5 outer ends offer stopping table 51 and ring set 41, encircle and cooperate, offer L draw-in groove 52 in the outer end of stopping table 51 and be connected anti-rotation bayonet lock 42 cooperations that ring set 41 is established with tailstock, tailstock 4 is fixed connection.
The present inventionTighten the fixedly connected mode of screw and axle sleeve by tailstock and change in the inner chamber of bellows component, offering and be connected ring set 41 and anti-rotation bayonet lock 42 and realize that bellows component fixedlys connected with cooperating of axle sleeve 5 original, reach the purpose of transmission by anti-rotation bayonet lock 42.Remove in axial dimension space that like this can original Cock screw is shared, reaches to reduce the bellows mechanical seal integral shaft to dimension volume, makes it to be installed in the narrow and small device space and use.And bellows component cooperates with draw-in groove 52 on the axle sleeve by bayonet lock 42, install very convenient fast, time saving and energy saving.

Embodiment
The present invention includes stationary ring, rotating ring, axle sleeve is installed, gland, as the bellows compensated ring component of rotating ring by friction ring 1, friction ring seat 2, bellows 3, tailstock 4 constitutes, friction ring 1 is inlaid on the friction ring seat 2, the rear and front end of bellows 3 is welded to connect with friction ring seat 2 and tailstock 4 respectively, inner ring surface at gland offers the seam groove, outer ring surface at stationary ring has the seam groove, the seam groove of offering on stationary ring and the gland inner ring surface cooperates installation, seam groove on the stationary ring outer ring surface is equipped with O-ring seals, form the seal ring sealing between stationary ring and gland, the ring end offers and connects ring set 41 in tailstock 4, ring set 41 is along the inner ring surface downside of stretching at bellows 3, be fixed with anti-rotation bayonet lock 42 at connection ring set 41, in axle sleeve 5 outer ends offer stopping table 51 and ring set 41, encircle and cooperate, offer L draw-in groove 52 in the outer end of stopping table 51 and be connected anti-rotation bayonet lock 42 cooperations that ring set 41 is established with tailstock, tailstock 4 is fixed connection, offer seal with O ring at tailstock 4 inner ring surfaces.
It uses when installingEarlier anti-rotation bayonet lock 42 is inserted in the L draw-in groove mouth of offering axle sleeves 5 outer ends, rotate after touching the end, fill in the L draw-in groove 52 on the axle sleeve 5 with fixed plate 6, prevention bayonet lock 42 withdraws from, and prevents that bellows component from deviating from from axle sleeve 5.Connecting the anti-rotation bayonet lock 42 and the draw-in groove 52 on the axle sleeve that are fixed with on the ring set 41 is that symmetry is offered.
