Abstract
The utility model relates to an integrated corrugated pipe mechanical seal device having at least one pair of coordinated movable ring and static ring. The utility model is characterized in that: a pin under the action of a spring is arranged on the movable ring tailstock; a pin hole fit with the pin is arranged on the inner end wall of a shaft sleeve, making the tailstock fixedly connected with the shaft sleeve; a static seal ring fit with the shaft is arranged on the movable ring tailstock; the shaft sleeve outer end is provided with a shaft sleeve flange; a binding screw is arranged on the shaft sleeve flange; and the shaft sleeve flange is connected with a limit fixing block which is fixedly connected with the shaft sleeve flange and a ring groove on a gland outside through the screw. The utility model is compact in structure, improves mechanical seal transmission reliability, reduces seal leakage probability, and is convenient to use and handle.
Description
Technical field
The utility model relates to mechanical seal device, is a kind of seal arrangement that prevents that working fluid from leaking along running shaft.
The prior art situation
Mechanical seal device for rubber bellows, by at least one pair of rotating ring and stationary ring perpendicular to axis, and rotating ring its end face and stationary 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.
Existing bellows mechanical seal, its rotating ring is the screw hole of offering by on its tailstock, is fixedlyed connected with axle sleeve by fastening screw trip bolt, and finishes the transmission of moment of torsion.Its shortcoming deficiency mainly shows as: the one, and physical dimension is bigger, structurally to have enough dimensional space arrange screw hole location with being connected of axle sleeve, the longer dimension of axle sleeve, the thickness of axle sleeve is bigger, to bear screw power, satisfy the fastening extruding of screw to axle sleeve prevent the distortion, and rotating ring with screw and axle sleeve be fastenedly connected be easy to generate loosening; The 2nd, a plurality of fastening screw trip bolts will be installed fastening also inconvenient one by one; The 3rd, the structure shape of axle sleeve and complicated with the linkage structure of axle, axle sleeve and between centers must be provided with static seal mechanism; The 4th, assembling is complicated.
Novel content
The purpose of this utility model is to improve at above-mentioned the deficiencies in the prior art, and a kind of compact structure that has is provided, and assembles and use unit loading type mechanical seal device for rubber bellows easy to loading and unloading.
The utility model includes the unit of at least one pair of rotating ring that cooperatively interacts 1 and stationary ring 2 assemblies composition, stationary ring 2 is fixedly connected under auxiliary seal ring 23 cooperates with end cap 3, rotating ring 1 is fixedlyed connected with axle sleeve 4, it is characterized in that on the tailstock 10 of rotating ring 1, offering the pin 15 that is subjected to spring 14 effects, on the inner end wall of axle sleeve 4, offer pin-and-hole 40, Elastip pin 15 on the tailstock 10 is connected with the pin-and-hole 40 on the axle sleeve 4, promptly with instrument Elastip pin 15 being pushed back earlier makes axle sleeve 4 insert tailstock 10, then Elastip pin 15 stretch out under 14 effects of its spring with axle sleeve 4 on the corresponding pin-and-hole of offering 40 cooperations, tailstock 10 is fixedlyed connected with axle sleeve 4, axle sleeve 4 drives rotating ring 1 and rotates, on the tailstock 10 of rotating ring 1, offer the static seal circle 17 that cooperates with axle, the outer end of axle sleeve 4 is provided with axle sleeve flange 42 and offers fastening screw trip bolt 44 on this axle sleeve flange 42, axle sleeve 4 is fixedlyed connected with axle with fastening screw trip bolt 44 by its axle sleeve flange 42, axle sleeve flange 42 is connected by the annular groove 31 of the spacing fixture block 6 of fixedlying connected with it by screw 61 with end cap 3 outsides, thereby make rotating ring 1, axle sleeve 4, stationary ring 2 integrates with gland 3, forms the mechanical seal device that a cover can be assembled fully in advance.
The utility model has overcome the shortcoming of prior art, its not only dwindled mechanical seal axial length, reduced the length of axle sleeve, make compact structure, also improved axle sleeve structure, the thickness of axle sleeve can fall, dwindle the radial dimension of mechanical seal device, axle sleeve structure is simple, and the static seal circle on the rotating ring tailstock is direct and an axle fitted seal, saved the static seal of axle sleeve with axle, make the reliable transmission raising of mechanical seal, the seal leakage probability falls, and assembles and uses easy to loading and unloading.
