How to maintain a two-way sealed butterfly valve
Bidirectional sealed butterfly valve is a fluid control device commonly used in pipeline systems, which has the characteristics of simple structure, small volume, light weight, and flexible operation. Regular maintenance is crucial to ensure the normal operation and extend the service life of a two-way sealed butterfly valve. The manufacturer of bidirectional hard sealed butterfly valves will provide a detailed introduction to the maintenance content and steps of bidirectional sealed butterfly valves.
1. Daily maintenance: (1) Regularly inspect the appearance of bidirectional sealed butterfly valves, including the valve body, valve cover, valve stem, blades, etc. for damage or corrosion. If necessary, clean and paint them. (2) Check the sealing performance of the bidirectional sealing butterfly valve, including the sealing condition of the valve seat, valve plate, and butterfly plate. If leakage or damage is found, the sealing components need to be replaced or repaired in a timely manner. (3) Check the operational performance of the bidirectional sealing butterfly valve, including manual and electric operation, to ensure that the valve can be opened and closed flexibly and smoothly. (4) For two-way sealed butterfly valves exposed outdoors, it is necessary to regularly clean the debris and dirt around the valve to avoid the erosion of harmful substances.

2. Regular maintenance: (1) Regularly check the lubrication of the bidirectional sealing butterfly valve, ensure that the connection between the valve stem and valve cover is filled with sufficient lubricating oil, and regularly add lubricating oil. (2) Regularly inspect the fasteners of the bidirectional sealing butterfly valve, including bolts, nuts, etc., to ensure that they are firmly connected. If there is any looseness or detachment, repair it in a timely manner. (3) Regularly inspect the anti-corrosion condition of the two-way sealed butterfly valve, and if necessary, perform rust removal and repainting to extend the service life of the valve. (4) Regularly check the sealing performance of the bidirectional sealing butterfly valve, including the sealing condition of the valve seat and butterfly plate. If leakage is found, the sealing components should be replaced in a timely manner.
3. Irregular maintenance: (1) When the two-way sealed butterfly valve is not in use for a long time, it should be inspected and maintained, including lubrication and sealing performance checks, to ensure that the valve can still be used normally after being out of service for a long time. (2) When there is a problem with the sealing performance of a bidirectional sealing butterfly valve, timely maintenance should be carried out, including replacing sealing parts, grinding valve seats, valve plates, etc., to ensure the normal operation of the valve.
In summary, the maintenance work of bidirectional sealed butterfly valves includes daily maintenance, regular maintenance, and irregular maintenance. By regularly inspecting the appearance, operational performance, and sealing performance of the valve, identifying and repairing problems in a timely manner, the normal operation and extended service life of the two-way sealed butterfly valve can be ensured. In addition, based on the actual situation and usage requirements, develop a reasonable maintenance plan, and equip corresponding tools and materials according to maintenance needs to ensure the smooth progress of maintenance work.
