Abstract
The invention discloses a dust-proof cover of a liquid storage drier. The dust-proof cover consists of a screwing convex body, a cover plate and a connection threaded column, wherein the screwing convex body is arranged on an outer end face of the cover plate; the connection threaded column is arranged on an inner end face of the cover plate; and the dust-proof cover is screwed in a detaching screw hole in an external surface of a piston type sealing cover through the connection threaded column. The liquid storage drier of an automotive air conditioner is designed to be in a split assembly type, so that the sealing performance of the whole liquid storage drier can be guaranteed, and the detachability of the sealing cover and a liquid storage cylinder can be realized. After a drying bag is unavailable, the sealing cover can be pulled out through the detaching screw hole, and then the drying bag can be normally used after replacement, so that the drying bag is convenient for replacement, the maintenance cost of the automotive air conditioner is reduced, the liquid storage drier of the automotive air conditioner becomes reusable, an automobile user gets a benefit, and a social benefit is more remarkable. By adoption of the dust-proof cover, dust can be prevented from entering the liquid storage cylinder from the sealing cover, and the detaching screw hole can be well protected.
Description
Technical field
The present invention relates to the liquid storage drier of air conditioning for automobiles, relate in particular to the dust cap of liquid storage drier.
Background technology
In automotive air-conditioning system, must be equipped with the liquid storage drier, the liquid storage drier on the automobile all is disposable use at present, must periodic replacement.Not only increased the operational maintenance maintenance cost of automobile, and the waste resource, do not meet current energy-conserving and environment-protective requirement.In order to change this present situation; The applicant has developed a kind of assembled auto air condition receiver drier; It can make auto air condition receiver drier and just can normally use as long as regularly change the molecular sieve drying bag; Can reduce the operational maintenance maintenance cost of automobile; Do not waste resource again, meet current energy-conserving and environment-protective requirement.Wherein dust cap is the dustproof part of liquid storage drier.
Summary of the invention
The dust cap that the purpose of this invention is to provide a kind of liquid storage drier; It can make auto air condition receiver drier and just can normally use as long as regularly change the molecular sieve drying bag; Can reduce the operational maintenance maintenance cost of automobile, not waste resource again, meet current energy-conserving and environment-protective requirement.
The technical scheme that the present invention takes is:
A kind of dust cap of liquid storage drier; It is characterized in that: form by screwing convex body, cover plate and connecting thread post; Screw on the outer face that convex body is arranged on cover plate; The connecting thread post is arranged on the inner face of cover plate, and dust cap is screwed on the piston type seal cover lateral surface through the connecting thread post and dismantles in the screw.
Further, the said convex body that screws is an outer-hexagonal.
Further, the said convex body that screws is to have interior hexagonal in the outer-hexagonal.
Because auto air condition receiver drier is designed to the split assembly type; Can guarantee the sealing property of whole auto air condition receiver drier; Can realize the detachability between seal cover and the liquid storage cylinder again; When dry bag uses the dismounting screw that can be provided with through the outer face of seal cover after the inefficacy seal cover is extracted; Changing dry bag can normally use; So both changed conveniently; Reduced the application maintenance cost of air conditioning for automobiles again; It is reusable that auto air condition receiver drier is become; Not only autoist income, and social benefit is more remarkable.The setting of dust cap can prevent that dust from getting in the liquid storage cylinder from seal cover, can also protect the dismounting screw.
