Sanitary diaphragm valve is a type of valve commonly used in industries such as food, pharmaceuticals, and beverages. The material of the diaphragm is stainless steel or polytetrafluoroethylene, which can prevent fluid contamination, ensure operational reliability and hygiene level. Today, the editor will take you to understand the operating steps of sanitary diaphragm valves.
1. Opening and closing of valves
When operating a sanitary diaphragm valve, the first step is to confirm the valve's open and closed status. Generally speaking, there will be corresponding markings on the operating handle of the diaphragm valve to indicate the position of the valve. When the operating handle is lowered, the valve is in the open state; When it is up, it is in the closed state. To ensure reliable opening and closing of the valve, the operating handle must be in the fully open or closed position and cannot be in a half open or half closed state.
2. Cleaning and disinfection
The cleaning and disinfection of sanitary diaphragm valves are important steps in ensuring production safety and quality. Before use and after material replacement, the diaphragm valve must be thoroughly cleaned and disinfected. The cleaning methods generally include mechanical cleaning, chemical cleaning, water washing, steam cleaning, etc. If serious impurities block or cannot be cleaned during use, appropriate cleaning media can be used for cleaning.
Disinfection methods include hot water disinfection, steam disinfection, hydrogen peroxide disinfection, etc. When disinfecting, it is important to note that the disinfectant should achieve the required disinfection effect. The disinfection time and temperature should be determined to meet the minimum requirements of hygiene regulations.
3. Replace the diaphragm
The material of the diaphragm directly affects the application range and performance of the diaphragm valve. Therefore, when replacing the diaphragm, it is necessary to strictly select materials that meet the application requirements. When replacing the diaphragm, the first step is to close the valve and remove the flange.
4. Protect the valve
One of the common causes of malfunctions in sanitary diaphragm valves is due to a lack of protection. During use, hard objects should be avoided from contacting valves, limiters, and other parts as much as possible; Do not overload or impact the valve; The gas consumption, pressure, and medium shall not exceed the set value of the valve.
