| Product Operate Guide
Preparation before operation
Check appearance: Carefully inspect the appearance of the valve to ensure that there are no obvious defects such as damage, deformation, cracks, etc. Especially in critical areas such as the sealing surface, valve body, and valve stem, any abnormalities may result in poor sealing or malfunction of the valve.
Confirm medium: Verify whether the medium applicable to the valve matches the actual working medium. Different media have different requirements for the material and sealing performance of valves. If the media does not meet the requirements, it may cause corrosion or damage to the valve, affecting its normal operation.
Check the gas source: Ensure that the pressure, flow rate, and other parameters of the gas source meet the requirements of the valve. Excessive or insufficient pressure of the gas source may cause the valve to fail to open or close properly, and even damage the pneumatic actuator. At the same time, check the cleanliness of the gas source to avoid impurities entering the pneumatic system, which may affect the sensitivity and reliability of the valve.
Check connection: Check whether the connection between the valve and the pipeline is firm and the seal is reliable. For sanitary butterfly valves, sanitary connection methods such as clamps and welding are usually used to ensure that the connection parts are not loose or leaking, in order to ensure the sealing and hygiene of the system.
Check electrical connections (if any): If the valve is equipped with an electrical signal feedback device or other electrical components, check whether its electrical connections are correct and secure, ensure normal signal transmission, and avoid valve misoperation or inability to monitor its working status due to electrical faults.
Operation steps
Open the valve
Manual operation (if any): If the valve is equipped with a manual operating mechanism, the butterfly valve can be opened through a manual device when the pneumatic system is not started. Manual operation is usually achieved through a handle or handwheel, rotating in the direction indicated on the handle or handwheel to fully open the butterfly plate. When operating manually, pay attention to applying even force to avoid damaging valve components due to excessive force.
Pneumatic operation: Connect the air source to the air inlet of the pneumatic actuator, open the air source valve, and allow compressed air to enter the cylinder. Under the action of air pressure, the piston or diaphragm inside the cylinder pushes the valve stem, drives the butterfly plate to rotate, and thus opens the valve. During the opening process, observe the opening of the valve to ensure that the butterfly plate can rotate smoothly and smoothly to the fully open position. If abnormal resistance or jamming is found during the opening process, the operation should be stopped immediately, the cause should be checked, and the fault should be eliminated.
Close the valve
Manual operation (if any): In contrast to opening the valve, close the butterfly valve through a manual device. Rotate the butterfly plate in the opposite direction as indicated on the handle or handwheel to the fully closed position. During the closing process, attention should be paid to controlling the force to avoid excessive force that may cause violent collision between the butterfly plate and the sealing surface, thereby damaging the sealing surface.
Pneumatic operation: Close the gas source valve and cut off the gas source. At this point, the air pressure inside the cylinder gradually decreases, and the butterfly plate gradually closes under the action of spring force or other reset devices. If the valve is equipped with a pneumatic positioner or other devices, the closing speed and accuracy of the valve can be controlled by adjusting the positioner. During the closing process, it is also necessary to observe the closing condition of the valve to ensure that the butterfly plate can tightly fit the sealing surface and achieve a good sealing effect. If it is found that the valve is not tightly closed, there may be problems such as damage to the sealing surface and blockage of impurities, which need to be checked and dealt with in a timely manner.
Check after operation
Check sealing performance: After the valve is closed, check its sealing performance. It can be checked by observing changes in the pipeline pressure gauge, using leak detection instruments to detect leakage points, or applying soapy water on the outlet side of the valve. If any leakage is found, the cause should be immediately investigated, which may be caused by damage to the sealing surface, aging or deformation of the sealing ring, poor sealing of the valve stem, etc. Relevant components need to be repaired or replaced in a timely manner.
Check valve status: Check whether all components of the valve are in normal condition, including whether the valve stem is flexible, whether the butterfly plate is in the correct position, and whether the pneumatic actuator is reset normally. If any abnormal situation is found, it should be adjusted or repaired in a timely manner to ensure that the valve can work normally during the next operation.
Cleaning valves: For sanitary butterfly valves, appropriate cleaning should be carried out after use. Select appropriate cleaning agents and methods based on the properties and hygiene requirements of the medium, clean the inner and outer surfaces of the valve, remove residual media, impurities, etc., and prevent microbial growth and contamination. After cleaning, ensure that the valve is dry to avoid residual moisture that may cause rusting or bacterial growth.
Record operation status: Record the operation status and inspection results of the valve in the equipment operation log. This helps to track and analyze the operating status of valves, facilitate the timely detection of potential problems, develop reasonable maintenance plans, extend the service life of valves, and ensure the safe and stable operation of the system.
