Abstract
The utility model belongs to mechanical seal field, particularly relates to the effective rotating sealing device of folding big orifice.Comprise inner housing section and coat part.It is characterized in that: described inner sleeve and coat part, all for the connection with pipeline.Beneficial effect: the folding effective rotating sealing device perfect performance of big orifice, be applicable to the connection for aircraft suction port and on-board air conditioner pipeline in airdrome ground service facilities and equipment, adaptable, cost is low, safe and reliable.Because Aerobiz is for the strict demand of on-board air conditioner and aircraft suction port UNICOM, utilizes the folding effective rotating sealing device of big orifice, virgin rubber cloth pipeline poor thermal insulation property can be solved completely, easily the shortcoming such as damage.Facts have proved, this device may be used for the safe operation of Aerobiz, technically, economically with environmental protection is all feasible.
Description
Technical field
The invention belongs to mechanical seal field, particularly relate to big orifice and fold changes in temperature ventilation duct swivel joint seal device.
Background technique
Mechanical sealing element technology is widely used in the fields such as national defence, electric power, chemical industry, oil, metallurgy, communications and transportation, medicine, food, cosmetics, the application that big orifice folds changes in temperature ventilation duct swivel joint seal device is an importance in mechanical seal field, belongs to a kind of folded pipeline seal arrangement.Big orifice folds changes in temperature ventilation duct swivel joint seal device mainly for airdrome ground service equipment facility, take off front and landing these two periods rear, airplane engine cuts out unpowered output, air-conditioning equipment cannot operate, in order to ensure the preference temperature of passenger in cabin, regulated by the mode of on-board air conditioner pipeline and aircraft UNICOM transporting cold-air or heating installation, the distance of on-board air conditioner and aircraft suction port is about 20 meters, adopts pipeline to connect.Traditional pipeline sealing device adopts the cloth pipeline of kiss-coating, although light, thermal insulation property extreme difference, therefore energy consumption more greatly and easily damage, and can not meet the high request for insulation on aircraft ground service application.At present, external had company to adopt stainless steel folded pipeline to add the folded pipeline design of thermal insulation layer, and for the UNICOM of pipeline and aircraft suction port, what pipeline burst adopted is exactly a kind of swivel joint seal device, but, adopt this solution without any a company at home.So big orifice folds changes in temperature ventilation duct swivel joint seal device and solves the problems referred to above, has filled up domestic blank, has improve efficiency, provided cost savings, ensured the safety of airport installation, the development for Aerobiz provides facility and ensures.
Summary of the invention
Main purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides big orifice to fold changes in temperature ventilation duct swivel joint seal device.This device may be used for the connection for aircraft suction port and on-board air conditioner pipeline in airdrome ground service facilities and equipment, technically, economically with environmental protection is all feasible.
The present invention for achieving the above object, by the following technical solutions: big orifice folds changes in temperature ventilation duct swivel joint seal device, comprises inner housing section and coat part.It is characterized in that: described inner sleeve and coat part, all for the connection with pipeline.
Beneficial effect: big orifice folds changes in temperature ventilation duct swivel joint seal device perfect performance, be applicable to the connection for aircraft suction port and on-board air conditioner pipeline in airdrome ground service facilities and equipment, adaptable, cost is low, safe and reliable.Because Aerobiz is for the strict demand of on-board air conditioner and aircraft suction port UNICOM, utilizes big orifice to fold changes in temperature ventilation duct swivel joint seal device, virgin rubber cloth pipeline poor thermal insulation property can be solved completely, easily the shortcoming such as damage.Facts have proved, this device may be used for the safe operation of Aerobiz, technically, economically with environmental protection is all feasible.Have the following advantages:
1. design of the present invention, realizes airdrome ground service equipment cart and carries the quick position installation of air-conditioning duct and aircraft suction port and depart from, solve the problem that common adhesive plaster pipeline energy consumption is larger, highly effective and safe, save financial cost.
2. design of the present invention, adopts the structure of full ball and inner-outer sleeve precise match, and internal, overcoat realizes strong support, ensure that oscillating quantity and the shifting amount of inside and outside cover, improves the operating accuracy of sealing.
3. design of the present invention, adopting rubber o-ring location graphite annulus, reducing the probability that major diameter graphite annulus damages when vibrating.
4. design of the present invention, have employed the structure that compensated loop is arranged on inner sleeve, shortens the length of integral sealing, provide cost savings.
5. design of the present invention, be applicable to 10 degrees Celsius to 60 degrees Celsius, air-conditioning body medium, 0.2Mpa with upward pressure, rotating speed is maximum reaches 10r.p.m.
Accompanying drawing explanation
Accompanying drawing 1 is structural drawing of the present invention.
Accompanying drawing 2 is seal arrangement enlarged views of the present invention.
Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.Its structural drawing is as shown in Figure of description.Big orifice folds changes in temperature ventilation duct swivel joint seal device, comprises inner housing section and coat part.It is characterized in that: described inner sleeve and coat part, all for the connection with pipeline.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
