Abstract
The utility model discloses a flexible shock-resistance mechanical sealing device, which comprises a shaft sleeve, a sealing seat, a spring seat, a spring, a pull ring, a static ring, a static ring sealing ring, a movable ring and a movable ring sealing ring, wherein the shaft sleeve is arranged on a rotating shaft, and the static ring is arranged in the sealing seat. The flexible shock-resistance mechanical sealing device is characterized in that the movable ring is connected with the shaft sleeve through more than two driving pins, the inner side wall of the movable ring is provided with more than two arc-shaped grooves, one end of each driving pin is arranged in the shaft sleeve, and the other end of each driving pin is arc-shaped and is positioned in the respective corresponding arc-shaped groove in the inner side wall of the movable ring. The flexible shock-resistance mechanical sealing device disclosed by the utility model has the capabilities of reducing the impact suffered by the movable ring and reducing the deformation and damage of the sealing surface of the movable ring, thereby prolonging the service life.
Description
Technical field
The utility model relates to a kind of mechanical seal device.
Background technique
Be used at present the mechanical seal device on all kinds of pumps, comprise the axle sleeve, sealing seat, spring seat, spring, the throw-out collar that are loaded in the rotating shaft, be loaded on stationary ring, stationary ring seal ring, rotating ring and seal ring of moving ring in the sealing seat, wherein set firmly rotating seat at axle sleeve, rotating seat links to each other with rotating ring by driving pin, but the end of the pin-and-hole on the rotating ring and driving pin certainly exists the gap, at pump startup with when stopping, can produce rotating ring and impact, time one is long, and rotating ring is fragile, affects the working life of equipment; Simultaneously existing seal ring of moving ring all is located in the annular seal groove of rotating seat, and rotating ring can't be adjusted in axial position, in case rotating ring is subjected to axial force, its sealing surface is yielding and damage, and also affects working life.
The model utility content
The purpose of this utility model is the above-mentioned deficiency for prior art, and a kind of flexible shock resistance mechanical seal device is provided, and it can reduce impact, minimizing rotating ring Deformation of Face Seal and the damage that rotating ring bears, thus the working life of extension device.
For achieving the above object, flexible shock resistance mechanical seal device of the present utility model, comprise the axle sleeve, sealing seat, spring seat, spring, the throw-out collar that are loaded in the rotating shaft, be loaded on stationary ring, stationary ring seal ring, rotating ring and seal ring of moving ring in the sealing seat, it is characterized in that rotating ring links to each other by plural driving pin with axle sleeve, be provided with plural curve bath at the rotating ring madial wall, one end of driving pin is loaded in the axle sleeve, and the other end of driving pin is arc and is arranged in the curve bath of each self-corresponding rotating ring madial wall.
Because the end of driving pin is cambered surface with the curve bath of rotating ring madial wall and contact, at pump startup with all can be to rotating ring generation impact when stopping, rotating ring be not fragile, the working life of extension device;
As further improvement of the utility model, rotating ring and axle sleeve are provided with adjacent shoulder, and a described seal ring of moving ring is between two shoulders; Axle sleeve in the rotating ring inboard is provided with seal groove, is provided with seal ring of moving ring in seal groove; The radial error of this two seal ring of moving ring when rotating ring is installed in Deformation of Face Seal, damage and compensation when bearing axial force so that rotating ring at axial and radial floating, can reduce respectively rotating ring;
As further improvement of the utility model, outside rotating ring, also be provided with protective metal shell; Can reduce hard particles in the medium to impact, the wearing and tearing of rotating ring;
In sum, the utility model can reduce impact, minimizing rotating ring Deformation of Face Seal and the damage that rotating ring bears, thus the working life of extension device.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Extremely shown in Figure 4 by Fig. 1, this flexibility shock resistance mechanical seal device, comprise the axle sleeve 2, sealing seat 3, spring seat 4, spring 5, the throw-out collar 6 that are loaded in the rotating shaft 1, be loaded on stationary ring 7, stationary ring seal ring 8, rotating ring 9 and two seal ring of moving ring 10,11 in the sealing seat 3, rotating ring 9 links to each other by two driving pins 12 with axle sleeve 2, be provided with two curve baths 13 at the rotating ring madial wall, one end of driving pin 12 is loaded in the axle sleeve 2, and the other end of driving pin 12 is arc and is arranged in the curve bath 13 of each self-corresponding rotating ring madial wall; Rotating ring 9 is provided with adjacent shoulder with axle sleeve 2, and described seal ring of moving ring 10 is between two shoulders; Axle sleeve 2 in rotating ring 9 inboards is provided with seal groove, is provided with seal ring of moving ring 11 in seal groove; Outside rotating ring 9, also be provided with protective metal shell 14;
The utility model is because the end of driving pin 12 is cambered surface with the curve bath 13 of rotating ring madial wall and contact, and at pump startup with all can be to rotating ring 9 generation impacts when stopping, rotating ring 9 be not fragile, but the working life of extension device; The radial error of two seal ring of moving ring 10,11 when rotating ring is installed in Deformation of Face Seal, damage and compensation when bearing axial force so that rotating ring 9, can reduce respectively rotating ring 9 at axial and radial floating; Protective metal shell 14 can reduce hard particles in the medium to impact, the wearing and tearing of rotating ring 9, further increases the service life.
