Description
Technical field
The utility model relates to a kind of seal arrangement, particularly relates to a kind of pneumatic-typed rubber swelling sealing.
Background technique
Seal arrangement is a kind of main part that generally uses in the mechanical industry, its application is very extensive, the normal seal arrangement that uses has mechanical seal, packing seal, sub-propeller sealing etc., and these seal arrangements are applied to the sealing position of distinct device, and good sealing effect is all arranged.Mechanical seal is used for seal fluid better effects, but it is not long to have liquid life-span of particle for sealing, and effect is relatively poor and price is more expensive, and manufacture cost is higher, during maintenance generally is to change a whole set of machine envelope, wastes also bigger.Though the packing seal cost is low, effect is bad, and maintenance is frequent, and the life-span is short.Sub-propeller is longer sealing life, but reliability is low, and sealing is the leak of liquid of the higher equipment of pressure incessantly, and it has increased the volume and weight of equipment, also want other auxiliary seal shared, and it is higher to consume energy.
The model utility content
The purpose of this utility model just be to provide a kind of simple in structure, economical and practical, use reliable, the life-span is long, purposes is wide, installation and maintenance pneumatic-typed rubber swelling sealing easily.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of pneumatic-typed rubber swelling sealing, comprised the rubber swelling gas-tight silo in seal casinghousing and the seal casinghousing, the rubber swelling gas-tight silo is set on the axle sleeve, it is characterized in that: described rubber swelling gas-tight silo has comprised rubber swelling gas-tight silo courage, steel ring and air intake valve, rubber swelling gas-tight silo courage is set on the steel ring, steel ring is fixed in the seal casinghousing, be installed on the air intake valve that communicates with the rubber swelling gas-tight silo on the seal casinghousing, seal casinghousing is interior to being provided with the cooling sump.
As further improvement of the utility model, be provided with 1 and above rubber swelling gas-tight silo in the utility model seal casinghousing as the backup seal storehouse, after the gas-tight silo wearing and tearing badly of work, can continue to use standby rubber swelling gas-tight silo, do not need hard stop to keep in repair and change part, improved working efficiency; Owing to enabled the backup seal storehouse, sealing station changes simultaneously, and the life-span of axle sleeve also obtains corresponding raising.
Compared with prior art, advantage of the present utility model is: the rubber swelling gas-tight silo adopts in the utility model pneumatic-typed rubber swelling sealing is wear-resisting or corrosion resistant and the rubber that can bear uniform temperature are made, by air intake valve gas-tight silo is inflated body or liquid, making gas-tight silo expand under the effect of pressure closely contacts with axle sleeve, reach the effect of sealing, it is simple in structure, economical and practical, use reliable, installation and maintenance are convenient, can be used for the sealing of distinct device, inflatable body or liquid in the gas-tight silo, purposes is in extensive range, be provided with the cooling sump in the seal casinghousing simultaneously, can the contact position of axle sleeve and gas-tight silo be cooled off and lubricate, reduce frictional loss, improved the life-span of part.
Description of drawings
Fig. 1 is the structural representation of rubber swelling gas-tight silo of the present utility model;
Fig. 2 is an embodiment's of the present utility model structural representation.
Marginal data:
1, seal casinghousing; 2, rubber swelling gas-tight silo; 3, air intake valve; 4, steel ring; 5, water inlet valve; 6, cooling sump; 7, axle; 8, rubber swelling gas-tight silo courage; 9, axle sleeve.
Embodiment
The utility model is described in further detail with concrete enforcement below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, the technical solution adopted in the utility model is: a kind of pneumatic-typed rubber swelling sealing, comprised the rubber swelling gas-tight silo 2 in seal casinghousing 1 and the seal casinghousing 1, rubber swelling gas-tight silo 2 is set on the axle sleeve 9, axle sleeve 9 is set on the axle 7, described rubber swelling gas-tight silo 2 has comprised rubber swelling gas-tight silo courage 8, steel ring 4 and air intake valve 3, rubber swelling gas-tight silo courage 8 is set on the steel ring 4, steel ring 4 is fixed in the seal casinghousing 1, be installed on the air intake valve 3 that communicates with rubber swelling gas-tight silo 2 on the seal casinghousing 1, the water inlet valve 5 that is provided with cooling sump 6 in the seal casinghousing 1 and communicates with it.Whole apparatus structure is simple, and is easy to use and reliable, and installation and maintenance are convenient.Rubber swelling gas-tight silo courage 8 or rubber swelling gas-tight silo courage 8 adopt the rubber of wear-resistant temperature-resistant or corrosion resistant to make with the contact position of axle 7, not only price economy, and the working life of having improved device.
In order further to improve the working life of device, reduce the maintenance user cost, be provided with rubber swelling gas-tight silo 2 more than 1 in the seal casinghousing 1 as the backup seal storehouse.After the gas-tight silo wearing and tearing of work are bad, can inflate body or liquid continues to use to standby rubber swelling gas-tight silo, reduce maintenance and changed part, it is fixed that what of backup seal storehouse can come according to the environment of main frame.After enabling the backup seal storehouse, because sealing station changes, axle sleeve contacts in new position again with the backup seal storehouse, so also corresponding being improved of the life-span of axle sleeve.
During use, the rubber swelling gas-tight silo 2 of unaerated body or liquid is contained on the axle sleeve 9, axle sleeve 9 is enclosed within on the axle 7, integral body is packed in the seal casinghousing 1, open air intake valve 3, gas or liquid to rubber swelling gas-tight silo 2 adding certain pressures make its slowly dilatancy, up to tightly waling axle sleeve 9, reach the effect of sealing.When work, the axle sleeve 9 of rotation can produce heat with the friction of rubber swelling gas-tight silo 2 banding positions, open water inlet valve 5, the cooling sump 6 that is arranged in the seal casinghousing and is close to rubber swelling gas-tight silo 2 is started working, the axle sleeve 9 and the banding position of rubber swelling gas-tight silo 2 are cooled off and lubricated, reduce frictional loss, improve part life.Though when work, rubber swelling gas-tight silo 2 had wearing and tearing with the banding position of axle sleeve 9, remaining pressure owing in the rubber swelling gas-tight silo 2, be always no gap between rubber swelling gas-tight silo 2 and the axle sleeve 9 and contact, sealing effect is good.
The sealing of the utility model pneumatic-typed rubber swelling can change according to the size of axle sleeve diameter, simultaneously can standardization, seriation, adapt to the diameter of axle requirement of different machines, simultaneously this device heat-resistant, wear-resistant corrosion resistant, can be applied to the machine sealing of different field, purposes haves a wide reach.
