Abstract
The utility model provides a sealing plug for an air suction and exhaust port of an automobile air-conditioning compressor. The sealing plug comprises a pressing plate, an air suction and exhaust port plug and a screw thread protection plug, wherein the air suction and exhaust port plug and a screw thread protection plug are respectively arranged at the two ends of the pressing plate. Compared with the prior art, the sealing plug for the air suction and exhaust port has good sealing effect, low cost and the like.
Description
Technical field
The utility model relates to compressor, relates in particular to a kind of automobile air conditioner compressor suction and exhaust ports sealing plug.
Background technique
When automobile air conditioner compressor (hereinafter to be referred as compressor) when dispatching from the factory; in order to make compressor when transporting for long-distance and place for a long time; compressor inside is not subjected to external environment (humid air or etchant gas) intrusion effect; to charging into shielding gas in the compressor, generally when dispatching from the factory, rotor-type compressor charges into nitrogen.The sealing plug of compressor air suction mouth and relief opening requires the shielding gas that fills certain pressure in the compressor is sealed, to avoid gas leakage.
Shown in Fig. 1～2, the intakeport sealing plug 1 and the relief opening sealing plug 2 of existing automobile air conditioner compressor generally are made up of two-part structure, rubber plug 11 and pressing plate 12, pressing plate 12 is provided with two holes, one of them installs rubber plug 11, insert by bolt, another hole 13 is fixed on sealing plug on the compressor, as shown in Figure 1, its sealing principle is the radially slight interference amount and the pretightening force realization sealing of tightening pressing plate by rubber plug, avoids the compressor internal pressure to cause rubber plug to jump out.Intakeport sealing plug 1 and relief opening sealing plug 2 are installed in the structural representation on the compressor, as shown in Figure 3.
Patent rubber seal plug (the patent No.: ZL98208816.7) be labyrinth shape rubber stopper (on footpath at the bottom of the rubber stopper, increasing by 3～4 circle seal rings 3), as shown in Figure 4 that the claimant is early stage.The rubber stopper that seal ring arranged can avoid with respect to the rubber stopper of no seal ring because the potential leakage hidden danger that the defective of rubber parts or suction and exhaust ports itself causes, and more near the protective action of the outer ring seal ring of flange edge more by force.
According to the actual use condition of vehicular compressed machine intakeport and relief opening sealing plug, above-mentioned sealing plug is to the not protection of tapped hole of intakeport and exhaust ports, and the impurity foreign matter easily enters tapped hole double thread tooth and causes damage in carrying or transportation process.
The main function of sealing plug promptly guarantees the sealing to compressor internal protection gas and lubricant oil.Not only safety but also realize that simply above-mentioned functions is exactly the design concept of sealing plug is how cut down some unnecessary parts and the cost of sealing plug is reduced and simplify assembling process also is good.
Summary of the invention
The purpose of this utility model is exactly in order to provide a kind of good sealing effect, automobile air conditioner compressor suction and exhaust ports sealing plug that cost is low.
In order to achieve the above object; the utility model has adopted following technological scheme: a kind of automobile air conditioner compressor suction and exhaust ports sealing plug; comprise pressing plate, suction and exhaust ports plug; it is characterized in that; also comprise the screw thread protection plug, described suction and exhaust ports plug and screw thread protection plug are separately positioned on the pressing plate two ends.
Be provided with the cambered outwards seal ring of multiple tracks on the outer surface of described suction and exhaust ports plug integratedly, the suction and exhaust ports aperture interference fit of sealing ring and compressor.
Described seal ring is provided with at least 3 circles.
Described suction and exhaust ports plug and screw thread protection plug and pressing plate integrated setting.
Described suction and exhaust ports plug and screw thread protection plug are rubber plug.
Described screw thread protection plug cooperates with suction and exhaust ports end-face helical interporal lacuna.
Compared with prior art, the utility model is by design new automobile air conditioner compressor intakeport and relief opening sealing plug, by the reasonable control of rubber stopper radial interference amount and the sealing of seal ring, can be good at realizing seal action to compressor internal protection gas and lubricant oil; Increase the tapped hole rubber plug, realize the protection to compressor air suction mouth and relief opening tapped hole, minimizing enters the damage that tapped hole double thread tooth causes because of compressor foreign matter in transportation process.Simultaneously, the be more convenient for dismounting of intakeport and relief opening rubber plug of incorporate design, integrated rubber stopper can also reduce the cost of sealing plug.

Embodiment
Shown in Fig. 5-8, a kind of automobile air conditioner compressor suction and exhaust ports sealing plug comprises pressing plate 4, suction and exhaust ports plug 5, also comprises screw thread protection plug 6, and described suction and exhaust ports plug 5 and screw thread protection plug 6 integrated setting are at pressing plate 4 two ends.Be provided with the cambered outwards seal ring 7 in three roads on the outer surface of suction and exhaust ports plug 5 integratedly, the suction and exhaust ports aperture interference fit of sealing ring 7 and compressor.Screw thread protection plug 6 cooperates with suction and exhaust ports end-face helical interporal lacuna.Suction and exhaust ports plug 5 and screw thread protection plug 6 are rubber plug.
Actual use condition according to vehicular compressed machine intakeport and relief opening sealing plug; increase the protection that screw thread protection plug 6 is realized vehicular compressed machine intakeport and relief opening tapped hole, minimizing impurity foreign matter in carrying or transportation process enters the probability that tapped hole double thread tooth causes damage.Screw thread protection plug 6 is a Spielpassung with tapped hole, can pack into easily, and Spielpassung can make the handle of tapped hole flange edge as dismounting intakeport and relief opening rubber plug, and being convenient to sealing plug must dismantle.The integrated rubber seal plug of intakeport and relief opening as shown in Figure 5.
This time the intakeport of design and relief opening sealing plug are used for the BWC series automobiles air condition compressor of Rili Electric Appliance Co Ltd, Shanghai's exploitation; be used to guarantee the shielding gas of compressor inside and completely cutting off of lubricant oil and space outerpace; avoid because water in air vapour, impurity enter compressor inside the infringement that compressor is caused.The scheme of installation of suction and exhaust ports sealing plug and screw thread protection plug is shown in Fig. 7～8.
Shown in Fig. 5-8, seal ring can according to the difference of seal length and sealing load, be provided with quantity at least 3 circles of seal ring according to the actual use condition of vehicular compressed machine intakeport and relief opening sealing plug.All the other are with embodiment 1.
