Vacuum Box Air Sealing Ring

Vacuum Box Air Sealing Ring - Shanghai Qingtu Rubber Technology Co., Ltd.

Inflatable sealing ringsCritical sealed components for vacuum drying chambersThe vacuum drying oven is widely used in research applications such as biochemical, chemical, medical health, agricultural research, and environmental protection. It is utilized for rapid drying processes of powders, baking, and drying heat-sensitive, easily decomposable, and oxidizable substances as well as complex composition items.This inflatable silicone rubber seal and its sealing structure feature simple structure, easy installation, excellent sealing performance, and the ability to achieve self-sealing in both axial and radial directions.The inflatable seal has guide positioning rings on its outer edge. When the upper and lower lips on the inner edge are clamped together, they form a complete hollow circular ring. After filling the high-pressure gas (or liquid) into the hollow circular ring within the pressure vessel, it expands outward, generating self-tightening properties in both axial and radial directions. The greater the internal pressure of the pressure vessel, the stronger the self-tightening effect, resulting in better sealing.

Qingtu Rubber specializes in inflatable sealing rings for pressure vessels. Over the years of production and operation, we have accumulated rich experience in the development and production of inflatable sealing rings. We have assisted numerous manufacturers in solving the sealing issues of open pressure vessels. When it comes to inflatable sealing, we are the experts.
