Abstract
The utility model discloses a mechanical sealing device, which comprises a limiting ring, a fastening screw, a positioning sleeve, a movable ring auxiliary sealing piece, a movable ring component, a stationary ring component, a spring, a small spring, a pressing cover, a pressing cover fixing screw and a stationary ring auxiliary sealing piece, wherein the movable ring component and the stationary ring component are central pieces; the movable ring auxiliary sealing piece is arranged at the outer edge of the movable ring component; the movable ring auxiliary sealing piece is tightly pressed by the movable ring component; the positioning sleeve is arranged outside the movable ring auxiliary sealing piece; the limiting ring is arranged at the outer end of the positioning sleeve through the fastening screw; the spring is arranged outside the stationary ring component; the pressing cover is arranged outside the spring; the stationary ring auxiliary sealing piece is arranged outside the pressing cover; the pressing cover is fastened and positioned by the pressing cover fixing screw; the small spring is arranged below a nut of the pressing cover fixing screw; and clamping devices are respectively arranged outside the movable ring component and the stationary ring component, the pre-pressing force of the auxiliary sealing pieces is effectively controlled, and conflict between spring force which is required by a mechanical sealing end face and the pre-pressing force of the auxiliary sealing pieces is avoided. The mechanical sealing device is simple in structure, high in stability and high in reliability.
Description
Technical field
The utility model relates to component of machine, relates in particular to a kind of mechanical seal device.
Background technique
The conventional mechanical sealing of existing technology; It generally is the sealing of adopting rotating ring or stationary ring to cooperatively interact and realize; At least should there be one to be to utilize the power effect that elastic element produced that mechanical seal self has or certain matching allowance and realize sealing in rotating ring and the stationary ring; Adopt the structural type of this sealing to fix, nonadjustable, having many inconveniences in the using process perhaps can not be satisfactory.
The model utility content
The purpose of the utility model is, overcomes the deficiency of existing technology, and a kind of mechanical seal device is provided, and can guarantee in use easy to adjustly, controls the preload pressure of secondary seal effectively.
The described a kind of mechanical seal device of the utility model includes limited ring, Cock screw, setting sleeve, rotating ring secondary seal, moving ring assembly, static components, spring, little spring, gland, gland set screw and stationary ring secondary seal.Moving ring assembly and static components are the parts placed in the middle of the utility model; In the outer side of moving ring assembly, be provided with the rotating ring secondary seal, moving ring assembly compresses the rotating ring secondary seal; The arranged outside of rotating ring secondary seal has setting sleeve, and the outer end of setting sleeve is provided with limited ring through Cock screw.The outside in static components is provided with spring, and the outside of spring is a gland, and the arranged outside of gland has the stationary ring secondary seal, and gland is fastening and location through the gland set screw, and the nut of gland fastening screw trip bolt is arranged with little spring.
The described a kind of mechanical seal device of the utility model; The outside in moving ring assembly and static components; Clamp device is set respectively, has controlled the pre-pressing force of secondary seal effectively, avoided because the contradiction of the pre-pressing force of required spring force of mechanical seal end surface and secondary seal.The described a kind of mechanical seal device of the utility model, overall structure is simple, and is easy to install and use, good stability, reliability is high.
Description of drawings
Accompanying drawing 1 is the structural representation of the said a kind of mechanical seal device of the utility model.1-limited ring, 2-Cock screw, 3-setting sleeve, 4-rotating ring secondary seal, 5-moving ring assembly, 6-static components, 7-spring, 8-little spring, 9-gland, 10-gland fastening screw trip bolt, 11-stationary ring secondary seal.
Embodiment
Existing with reference to accompanying drawing 1; Explain as follows in conjunction with embodiment: the described a kind of mechanical seal device of the utility model includes limited ring 1, Cock screw 2, setting sleeve 3, rotating ring secondary seal 4, moving ring assembly 5, static components 6, spring 7, little spring 8, gland 9, gland set screw 10 and stationary ring secondary seal 11.Moving ring assembly 5 is parts placed in the middle of the utility model with static components 6; Outer side at moving ring assembly 5; Be provided with rotating ring secondary seal 4; Moving ring assembly 5 compresses rotating ring secondary seal 4, and the arranged outside of rotating ring secondary seal 4 has setting sleeve 3, and the outer end of setting sleeve 3 is provided with limited ring 1 through Cock screw 2.In the outside of static components 6, be provided with spring 7, the outside of spring 7 is glands 9, and the arranged outside of gland 9 has stationary ring secondary seal 11, and gland 9 is through gland set screw 10 fastening and location, and the nut of gland fastening screw trip bolt 10 is arranged with little spring 8.The described a kind of mechanical seal device of the utility model; The outside in moving ring assembly 5 and static components 6; Clamp device is set respectively, has controlled the pre-pressing force of secondary seal effectively, avoided because the contradiction of the pre-pressing force of required spring force of mechanical seal end surface and secondary seal.The described a kind of mechanical seal device of the utility model, overall structure is simple, and is easy to install and use, good stability, reliability is high.
