Abstract
The utility model provides a filler sealing device which comprises a filler gland (2), a rotating shaft (7), a filler box (9) sleeving on the rotating shaft, and a filler end cap (1) arranged on the filler box (9). A filler cavity formed by surrounding of the filler box (9), the rotating shaft (7), the filler end cap (1) and the filler gland (2) is filled with sealing filler (8), the filler end cap (1) and the filler gland (2) are connected through a bolt structure which comprises a bolt (4) and a nut (5), the bolt (4) sequentially penetrates the filler gland (2) and the filler end cap (1), an elastic pressing plate (6) is arranged on the bolt between the nut (5) and the filler gland (2) in a sleeved manner, and a spring (3) is arranged between the elastic pressing plate (6) and the filler gland (2). The spring and an elastic gland are additionally arranged between the filler gland and the nut of the connecting bolt, so that the filler is automatically compressed under action of the elastic gland.
Description
Technical field
The utility model relates to technical field of chemical, particularly a kind of stuffing seal.
Background technique
Packing seal is widely used in the shaft sealing design of transmission device.Filler is a kind of for sealing the contact Sealing of slidingsurface, thereby he compresses soft packing in closed chamber by means of axial force the requirement that filler is compressed produce side pressure (radial pressure) to seal leak fluid to reach sealing.In prior art, the friction power loss on filler and axle surface is large, heavier the closer to the place wearing and tearing of gland, cause mechanical efficiency low, need artificial cycle to compress or change filler in equipment running process, later stage leakage rate is large, change frequently, inconvenient maintenance, operating cost is high.
Model utility content
For solving the problem existing in background technique, the purpose of this utility model is achieved through the following technical solutions:
A kind of stuffing seal, comprise Gland (2), rotating shaft (7), be enclosed within the Stuffing box (9) in rotating shaft, be arranged on the filler end cap (1) on Stuffing box (9), described Stuffing box ((9), rotating shaft (7), in the packing cavity that filler end cap (1) and Gland (2) surround, be filled with stuffing box packing (8), between filler end cap (1) and Gland (2), connect by bolt arrangement, described bolt arrangement comprises bolt (4) and nut (5), described bolt (4) is successively through Gland (2) and filler end cap (1), on bolt between nut (5) and Gland (2), cover is provided with elastic force pressing plate (6), between elastic force pressing plate (6) and Gland (2), be provided with spring (3).
Between Stuffing box and rotating shaft, be filled with soft-filler layer, filler is by Gland compacting, and Gland regulates the elasticity of Gland by elastic force pressing plate under the elastic force effect of spring, thereby reaches the effect of sealing.
Owing to having used spring body structure, the pressure of rotating shaft pressure-bearing surface is even, and rotating shaft wearing and tearing are little and even, and elastic force has the tight ability of mending, leakage that can effective sealing fluid.
Working procedure of the present utility model is summarized as follows:
Axle does along axle center and rotates, and filler side is full of by liquid, and liquid produces radial pressure around to filler and rotating shaft thereof, and filler produces backpressure under the effect of filler end cap, and this backpressure is greater than liquid to filler applied pressure.Gland, under the elastic force effect of spring, is adjusted the active force that Gland applies filler, keeps filler to have enough lubricated and elastic force, and the pressure that maintains rotating shaft aspect is even, and rotating shaft is effectively being turned round under sealed environment.
The utility model is compared with prior art, and its effect is actively with obvious.Spring and elastic force gland are set up in packing seal of the present utility model between filler friction top and the nut of connecting bolt, and filler is automatic impaction under the effect of elastic force gland.
Brief description of the drawings
Fig. 1 is the utility model gland sealed cross-sectional view.
In Fig. 1, filler end cap 1, Gland 2, spring 3, bolt 4, nut 5, elastic force gland 6, rotating shaft 7, filler 8, Stuffing box 9.
Embodiment
The utility model is described in further details by embodiment below in conjunction with accompanying drawing.
A kind of stuffing seal, comprise Gland (2), rotating shaft (7), be enclosed within the Stuffing box (9) in rotating shaft, be arranged on the filler end cap (1) on Stuffing box (9), described Stuffing box ((9), rotating shaft (7), in the packing cavity that filler end cap (1) and Gland (2) surround, be filled with stuffing box packing (8), between filler end cap (1) and Gland (2), connect by bolt arrangement, described bolt arrangement comprises bolt (4) and nut (5), described bolt (4) is successively through Gland (2) and filler end cap (1), on bolt between nut (5) and Gland (2), cover is provided with elastic force pressing plate (6), between elastic force pressing plate (6) and Gland (2), be provided with spring (3).
Between Stuffing box and rotating shaft, be filled with soft-filler layer, filler is by Gland compacting, and Gland regulates the elasticity of Gland by elastic force pressing plate under the elastic force effect of spring, thereby reaches the effect of sealing.
Owing to having used spring body structure, the pressure of rotating shaft pressure-bearing surface is even, and rotating shaft wearing and tearing are little and even, and elastic force has the tight ability of mending, leakage that can effective sealing fluid.
Working procedure of the present utility model is summarized as follows:
Axle does along axle center and rotates, and filler side is full of by liquid, and liquid produces radial pressure around to filler and rotating shaft thereof, and filler produces backpressure under the effect of filler end cap, and this backpressure is greater than liquid to filler applied pressure.Gland, under the elastic force effect of spring, is adjusted the active force that Gland applies filler, keeps filler to have enough lubricated and elastic force, and the pressure that maintains rotating shaft aspect is even, and rotating shaft is effectively being turned round under sealed environment.
Claims (1)
