Abstract
A Energy saving type shut-off leakless seal device is characterized in that the utility model comprises a plurality of elastic mechanical sealing rings (1), a plurality of O-shaped static sealing rings (2), a sealed letter (3), a pressure part (4), wherein the inner sides of the elastic mechanical sealing rings is connected rotatably with a rotating shaft and the other sides of the elastic mechanical sealing rings is connected with the sealed letter (3) and the pressure part (4) to form a backsurge chamber (5), a pressure cooling chamber (6) and a lubricative dustproof chamber (7); O-shaped static sealing rings (2) are inserted between the sealed letter (3) and a shell (8); a water inlet (9), a water outlet (10) and a lubricating grease inlet (11) are arranged between the shell and the rotating shaft. The utility model has functions of shutting off water, blocking up leaks, washing and cooling and lubricating and dust resisting.
Description
The utility model relates to a kind of energy-saving shutoff type inclusion seal device, belongs to fluid machinery shaft sealing field.
Axle envelope for fluid machineries such as pump and blower fans generally adopts packing seal, sub-propeller dynamic seal and mechanical seal at present.Wherein packing seal structure is simple, and is cheap, but can not avoid leaking, and power consumption is bigger, and the filler life-span is short, changes frequently, and labor intensity is big; Though can accomplish zero leakage during sub-propeller dynamic seal work, complex structure, service condition is restricted, and parking sealing arrangement need be set, its power consumption maximum; Though mechanical seal can reach zero leakage, power consumption is little, and complex structure uses and installation conditions requires height, and price is expensive.Therefore the axle envelope problem of fluid machinery is that people need update, and upgrades and urgent hard nut to crack to be solved.
The purpose of this utility model is to provide a kind of energy-saving shutoff type inclusion seal device at the deficiencies in the prior art, be characterized in adopting the seal that contains a plurality of elasticity dynamic seal rings and a plurality of O type static seal circle composition, it has the leak stopping of damming, flushing cooling and lubricated dust-tight function.
The purpose of this utility model is realized by following technical measures
Energy-saving shutoff type inclusion seal device contains a plurality of elasticity dynamic seal rings (1), a plurality of O type static seal circles (2), sealed letter body (3) and compressing member (4), the inner side surface of elasticity dynamic seal ring and rotating shaft flexibly connect, the other end is connected with compressing member (4) with sealing letters (3), constitute backwash chamber (5), band is pressed cooling chamber (6) and lubricated dustproof room (7), O type static seal circle (2) is embedded between sealing letters (3) and housing (8), be provided with water intake (9) and water outlet (10) between housing (8) and the rotating shaft, also be provided with lubricating grease inlet (11) between housing and the rotating shaft.
Elasticity dynamic seal ring (1) is by root (12), and belly (13) and lip (14) are formed, elasticity dynamic seal ring inboard be provided with spiral chute to axial plane, lip can be held tightly in rotating shaft automatically behind the pressurized.
According to the difference of the character of escape of liquid medium, temperature, pressure, can adopt the seal that component such as a plurality of elasticity dynamic seal rings and a plurality of O type static seal circles form respectively or have only flushing and lubricated or cooling and lubricated part seal.
Look the difference of escape of liquid medium, the material of seal ring is heatproof, wear-resisting, oil resistant, water-fast and corrosion resisting elastic material, and this device is specially adapted to have the sewage medium of impurity such as silt.
The utlity model has following advantage:
1, type selecting is proper, uses rationally, can reach not have to leak.
2, dress folding, maintenance, replacing are than mechanical seal conveniently.
3, the friction power consumption is little, obvious energy conservation.
4, few easy workout part, the life-span is long, and price is more cheap, can be applicable in China, has remarkable economic efficiency and society to change benefit.
Concrete structure of the present utility model is provided by the following drawings and embodiment
Fig. 1 is a shutoff type inclusion seal apparatus structure schematic representation
1 elasticity dynamic seal ring, 2O type static seal circle, 3 sealing letters, 4 compressing members, 5 backwash chambers, 6 bands are pressed cooling chamber, 7 lubricated dustproof rooms, 8 housings, 9 water intakes, 10 water outlets, 11 lubricating grease inlet

Embodiment
With embodiment concrete structure of the present utility model is described below, and embodiment is not regarded as the restriction of the utility model protection domain, the person skilled in the art of related domain can make some nonessential improvement and adjustment to the utility model according to foregoing.
Energy-saving shutoff type inclusion seal device such as Fig. 1 are shown in Figure 2.It is by the elasticity dynamic seal ring 1 of a plurality of band self tightening lips, and a plurality of O type static seal circles 2 seal letters 3 and compressing member 4 is formed.The inner side surface and the rotating shaft of the elasticity dynamic seal ring of band self tightening lip flexibly connect, the other end is connected with compressing member 4 with sealing letters 3, constitute backwash chamber 5, band is pressed cooling chamber 6 and lubricated dustproof room 7, O type static seal circle 2 is embedded between sealing letters 3 and housing 8, be provided with water intake 9 and water outlet 10 between housing 8 and the rotating shaft, also be provided with lubricating grease inlet 11 between housing and the rotating shaft.Elasticity dynamic seal ring 1 is by root 12, and belly 13 and lip 14 are formed.Elasticity dynamic seal ring inboard be provided with spiral chute to axial plane, lip is a self tightening, has suitable magnitude of interference, can hold tightly on axle automatically behind the pressurized, but the friction of countershaft is less.According to the difference of the character of escape of liquid medium, temperature, pressure, can adopt the seal that component such as the elasticity dynamic seal ring of a plurality of band self tightening lips and a plurality of O type static seal circles form respectively or have only flushing and lubricated or cooling and lubricated part seal.Look the difference of escape of liquid medium, the material of seal ring is heatproof, wear-resisting, oil resistant, water-fast and corrosion resisting elastic material, and this device is specially adapted to have the sewage medium of impurity such as silt, and effect is very remarkable.
During work, the sealing letters are erected three defence lines, at first, have the external backwashing pressure water that exceeds leak pressure 0.1MPa and by backwash chamber leaking medium are carried out backwash, this is even more important to the medium that contains impurity, and leaking medium was dammed before backwash chamber.Simultaneously, outer tape splicing cooling water pressure enters cooling chamber, makes seal ring lip self-tightening, obtain cooling, constitute the defence line, second road of leaking medium, in lubricated dustproof room, regularly inject lubricating grease at last, seal lip is lubricated, prevent that air and foul from being entered in the Seal cage by the external world.
