What is the working principle of pneumatic aseptic sampling valve?
The pneumatic aseptic sampling valve is used for disinfection by opening the valve and closing the valve by cutting off air, keeping the channel between the hose open. Sterile sampling valves are mainly used for sample collection of materials inside tank equipment or pipes, and require sterilization before and after each sampling. Aseptic sampling can be performed continuously and at any time. Widely used in food, wine, beverage, dairy products, toothpaste, cosmetics, biopharmaceutical and other industries.
Pneumatic aseptic sampling valve working principle: the aseptic sampling valve is mainly divided into pneumatic components, valve body, diaphragm sealing ring these parts. When in the closed state, rely on the spring tension to push the spool, by the spool will seal the sealant head at the valve body material inlet to achieve the sealing effect
After the sampling is completed, close the air source, relax the spring, press the sealant head at the material inlet of the valve body again through the valve core; The residual liquid in the sample room is discharged through clean water (if the sample is a cleaner medium such as sterile water, this step can be omitted), and then the sterilization medium is injected to seal and retain until the next sample.
