Abstract
The utility model relates to a mechanical sealing device of a corrugated pipe, which has the characteristics of good sealing effect, long service life and automatic compensation. The mechanical sealing device of a corrugated pipe is composed of the main piece of a corrugated pipe, a press cover pad, a press cover, a stationary ring, a sealing ring, a shaft seal, etc. A corrugated pipe component (5) and a movable ring (15) are fixed, and the stationary ring (7) is fixed on the press cover (11). The movable ring (15) contacts the stationary ring (7), and the movable ring (15) and the stationary ring (7) are both arranged on a shaft. The utility model has the advantages of simple structure and easy realization and is suitable for the fields of petroleum, chemical industry, medicine, etc.
Description
The utility model relates to seal arrangement manufacturing technology field in the industries such as oil, chemical industry, medicine, and exactly it is a kind of mechanical seal device for rubber bellows.
At present, in fields such as oil, chemical industry, medicine, refrigeration, seal arrangement often uses graphite packing, asbestos rope to seal, and this kind sealing means is easily revealed, and the life-span is short, changes frequent.And the medium in the above-mentioned field has temperature and pressure mostly, also contains corrosive liquids (gas) such as soda acid simultaneously.Thereby if a kind of good sealing effect is arranged, the life-span is long, the seal arrangement of acid resistant alkali will be subjected to oil, chemical industry, the welcome of medicine and other fields.
The purpose of this utility model provides a kind of for oil, chemical industry, medicine, refrigeration, the mechanical seal device for rubber bellows that use in fields such as power station.It not only is difficult for revealing, and long service life.
The purpose of this utility model is achieved by the following scheme, it is by the bellows main part, compositions such as gland pad, gland, stationary ring, seal ring, axle envelope, it is characterized in that: bellows component (5) fixes with rotating ring (15), stationary ring (7) is fixed on the gland (11), rotating ring (15) contacts with stationary ring (7), and they all are contained on the axle.Bellows component (5) is made up of axle sleeve (1), bellows (16) and rotating ring (15), is connected with bolt (2) between bellows (16) and the axle sleeve (1), at bellows (16) and axle sleeve (1) connecting place sealing gasket (4) is housed.Be with O type circle (9) and seal ring (10) on the stationary ring.Axle sleeve (1) end and gland (11) end are equipped with axle envelope (13) and (14) respectively.
The utility model has the advantages that: good sealing effect, long service life, acid resistant alkali also has automatic compensation function, and Applicable scope is extensive.
Below in conjunction with drawings and Examples the utility model is done further detailed description.
Fig. 1 is the utility model structural representation.
1 is axle sleeve among the figure, and 2 is screw, and 3 is packing ring, and 4 is sealing gasket, and 5 is bellows component, and 6 is the gland pad, 7 is stationary ring, and 8 is stop pin, and 9 is O type circle, and 10 is seal ring, and 11 is gland, and 12 is water jacket, 13 is the axle envelope, and 14 is the axle envelope, and 15 is rotating ring, and 16 is bellows, and 17 is axle.
O type circle, seal ring, screw are outsourcing piece in the utility model, and the factory that all the other component possess general machining equipment all can make.Get all the shown in the accompanying drawing that assembling gets final product with reference to accompanying drawing behind the component ready.According to employed pump the axle diameter, processing seal arrangement size.Axle sleeve (1) and coupled bellows (16) are contained on the axle (17), stationary ring (7) is fixed on (welding) on gland (11), assemble with reference to accompanying drawing.During running, oil can be sealed at dynamic and static ring junction plane place, and the machining accuracy of dynamic and static ring is very high, and by the tension force of bellows, the dynamic and static ring junction plane can be pressed to such an extent that root is tight, thereby can not reveal.During running, the dynamic and static ring place can generate heat, and can lower the temperature by the cooling bath on the gland.After operation after a while, dynamic and static ring can be worn, but can compensate automatically by the tension force of bellows.
