Technical Field

The invention relates to the technical field of solar water tanks, in particular to an integrated dustproof sealing sleeve.

Background

As is well known, the foaming of a solar water tank or header is to foam an outer barrel-inner barrel assembly formed by assembling an outer barrel and an inner barrel and accessory assemblies thereof. Before foaming, the foaming plugs are plugged into the pipe openings of the outer barrel and the inner container.

After the foaming operation is finished, the foaming plug needs to be pulled out, parts such as a sealing ring and the like installed at the opening of the inner pipe are cleaned, the subsequent installation operation is facilitated, however, the cleaning of the foamed solar water tank or the header is very inconvenient, the labor intensity of workers is high, the efficiency is low, and the efficient production of the solar water tank or the header is not facilitated. Therefore, the integral dustproof sealing sleeve is necessary to be convenient for the extraction of the foaming plug, avoid the cleaning of the opening of the inner liner tube and the foaming plug and reduce the labor intensity of workers.

Disclosure of Invention

The invention aims to provide an integrated dustproof sealing sleeve which is convenient for the extraction of a foaming plug, avoids the cleaning of an inner bile duct opening and the foaming plug and reduces the labor intensity of workers.

The invention is realized in such a way that the integrated dustproof sealing sleeve comprises a dustproof cover and a sealing ring, wherein an isolation sleeve is arranged between the dustproof cover and the sealing ring;

the front end of the isolation sleeve is connected with the rear end of the sealing ring in a sealing mode, and the rear end of the isolation sleeve is connected with the front end of the dust cover in a sealing mode.

As an improved scheme, the isolation sleeve is an elastic isolation sleeve.

As an improved scheme, the isolation sleeve is a thin-wall elastic sleeve.

As an improvement, the spacer sleeve is provided with a plurality of annular folds along the axial direction thereof.

As an improved scheme, the cross section of the annular pleat is of a V-shaped structure.

As an improved scheme, the isolation sleeve is in a conical sleeve structure with a small front part and a large rear part.

As an improved scheme, the inner wall of the isolation sleeve is a smooth wall surface, and the outer wall of the isolation sleeve is a rough wall surface.

As an improved scheme, the inner diameter of the front end of the isolation sleeve is larger than the inner diameter of the rear end of the sealing ring, and a chamfer is formed at the junction of the rear end face of the sealing ring and the inner wall of the sealing ring.

As an improved scheme, the isolation sleeve is made of silica gel.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

according to the integrated dustproof sealing sleeve provided by the invention, the isolation sleeve is arranged between the dustproof cover and the sealing ring, the front end of the isolation sleeve is hermetically connected with the rear end of the sealing ring, and the rear end of the isolation sleeve is hermetically connected with the front end of the dustproof cover, so that a foaming plug can be conveniently taken out after foaming operation, the cleaning is avoided, the integrated dustproof sealing sleeve is directly used, and the integrated dustproof sealing sleeve is convenient and quick and can effectively prevent dust.

The isolation sleeve is arranged to be an elastic isolation sleeve, and the elastic structure of the isolation sleeve facilitates the installation and use of the integrated dustproof sealing sleeve;

the isolation sleeve is arranged to be of a thin-wall structure, so that the isolation sleeve has good compression and tension performance and is convenient for installation of the integrated dustproof sealing sleeve;

the isolating sleeve is provided with a plurality of annular folds along the axial distribution thereof, the cross section of the annular folds is of a V-shaped structure, so that the isolating sleeve has good flexibility, the integrated dustproof sealing sleeve is convenient to install, a certain air separation cavity can be formed on the isolating sleeve after foaming, and the foaming plug can be further conveniently plugged and taken out.

The isolation sleeve is arranged to be a conical sleeve structure with a small front part and a large rear part, and the foaming plug can be conveniently taken out after the foaming work is finished.

Because the inner wall of the separation sleeve is set to be a smooth wall surface, and the outer wall of the separation sleeve is set to be a rough wall surface, the effective bonding of the polyurethane foaming glue and the outer wall of the separation sleeve can be effectively ensured, and meanwhile, the smooth inner wall is convenient for the filling in and the taking out of the foaming plug.

After adopting above-mentioned structure, this integral type dustproof sealing cover is convenient for install, use, during the use, fills in integral type dustproof sealing cover between inner bag and the outer bucket, makes things convenient for filling in of foaming stopper, carries out foaming work, then can swiftly take out the foaming stopper, need not to clear up sealing washer, dust cover and foaming stopper.

The inner diameter of the front end of the isolation sleeve is larger than that of the rear end of the sealing ring, so that the foaming plug can be effectively limited and can be conveniently plugged and taken out; the chamfer angle is arranged at the junction of the rear end face of the sealing ring and the inner wall of the sealing ring, so that the foaming plug can be effectively and conveniently taken out.

Because the isolating sleeve made of the silica gel material is adopted, the heat dissipation in the foaming process of the polyurethane foaming glue can be effectively ensured without influencing the isolating sleeve.

The integrated dustproof sealing sleeve provided by the invention is effective in dust prevention, is convenient for the foaming plug to be plugged and pulled out, avoids the cleaning of the inner bile duct opening and the foaming plug, reduces the labor intensity of workers, improves the working efficiency and reduces the production cost.
