Aseptic Diaphragm Valves Have Been Used In Many Fields Due To Their Special Performance And Advantages.
Sanitary Diaphragm Valve uses a diaphragm made of soft materials such as rubber or plastic as a start-and-stop part. The diaphragm moves up and down to close or open the flow channel, thereby cutting off or allowing the fluid to pass. The diaphragm separates the inner cavity of the valve body and the inner cavity of the valve cover to ensure that the medium will not contact the valve stem, valve disc and other components, thereby avoiding corrosion and leakage of the medium.
Structure and characteristics of aseptic diaphragm valve:
Structural composition: It is mainly composed of valve body, diaphragm, driver (such as manual, pneumatic, electric, etc.) and possible automatic control devices.
Features:
High sealing: The material and structure of the diaphragm ensure the high sealing of the valve and effectively prevent medium leakage.
Corrosion resistance: Since the diaphragm and valve body can be made of a variety of corrosion-resistant materials, it is suitable for a variety of corrosive media.
Easy to clean and maintain: The structure is simple, easy to disassemble and clean, and the maintenance cost is reduced.
Aseptic diaphragm valves have been widely used in many fields due to their special performance and advantages:
Pharmaceutical industry: used for material transportation in aseptic production lines, inlet and outlet of reactors, etc., to ensure the sterility and safety of products.
Biotechnology: In cell culture, fermentation, extraction and other processes, krypton is used to control the flow of media to prevent contamination.
Food processing: In beverage, dairy, brewing and other industries, it is used to process fluid food to ensure the hygiene and quality of products.
Microelectronics and chemical industry: It also plays an important role in the transportation of ultrapure water and the treatment of chemicals.
Selection and precautions of aseptic diaphragm valves:
Selection: When selecting, factors such as the properties of the medium (such as corrosiveness, viscosity, temperature, etc.), working pressure, flow requirements and installation environment need to be considered. In addition, it is necessary to select the appropriate driver and control method according to the specific application scenario.
Precautions:
Regularly check the wear of the diaphragm and replace the damaged diaphragm in time.
Ensure that the installation position of the valve meets the design requirements to avoid excessive stress and torque.
During use, pay attention to monitoring the sealing performance and flow characteristics of the valve, and identify and handle problems in a timely manner.
