Stainless Steel Sanitary Normal Tank Cover Pressure Round Manhole
The design goal of the stainless steel sanitary normal pressure circular manhole is to provide a convenient and safe operation entrance while maintaining the normal pressure and high hygiene standards inside the equipment. It is specially designed to ensure that the staff can enter the container for necessary inspection, cleaning, maintenance or repair without destroying the sealing of the equipment. Its circular structure not only makes the manhole more secure and easy to seal, but also effectively reduces dead corners, avoids residual pollutants, ensures the sanitation and safety of the production environment, and meets strict hygiene requirements.
Working Principles
The working principle of the stainless steel sanitary normal pressure circular manhole is mainly achieved through its sealing structure and opening mechanism. During normal operation, the manhole remains sealed to ensure that the equipment maintains normal pressure and prevents external contaminants from entering. When inspection, cleaning or maintenance is required, the operator releases the seal manually or through a quick opening mechanism to enter the equipment. When opening, the handle or quick lock releases the manhole cover, and the cover can be opened safely without affecting the internal pressure of the equipment during this process. When closed, the sealing ring ensures re-sealing and no leakage during operation, ensuring the hygienic safety of the equipment.
The options for stainless steel sanitary normal pressure round manholes include:
Material selection: 304, 316L stainless steel.
Opening method: manual opening, quick opening.
Sight glass configuration: with sight glass, without sight glass.
Sealing method: rubber sealing ring, silicone sealing ring.
Cover type design: flat cover type, convex type.

Features
● The stainless steel sanitary normal pressure circular manhole is designed with an adjustable sealing pressure system. By adjusting the pressure of the sealing ring, it ensures that the manhole cover can maintain the best sealing effect under different operating environments.
● The stainless steel sanitary normal pressure circular manhole is equipped with a double sealing ring design, with a layer of high-pressure sealing ring and a layer of low-pressure sealing ring superimposed to enhance the sealing effect and prevent leakage.
● The stainless steel sanitary normal pressure circular manhole adopts a quick disassembly structure, which is convenient for quick opening and resealing, saving time and ensuring safe operation.
● The inner and outer surfaces of the stainless steel sanitary normal pressure circular manhole are precisely polished to reduce the accumulation of impurities and the difficulty of cleaning, and ensure hygiene requirements.
● The stainless steel sanitary normal pressure circular manhole is equipped with an explosion-proof device to prevent the risk of explosion caused by pressure fluctuations under extreme operating conditions.
● The stainless steel sanitary normal pressure circular manhole is designed with a variety of pipe interface forms, which can be compatible with pipes of different sizes and types, providing more adaptation options.
