Electric butterfly valve common fault analysis and release method

We always find this type of failure or failure when using an electric butterfly valve. It is very important to know the correct method of elimination. Being able to perform repairs in time when a product failure occurs or to avoid the possibility of failure. For example, before we install, we should consider and observe that the performance of the product used is consistent with the direction of the fluid in the working environment, and it must meet the conditions of the sports condition.
Before we use it, we should clean the inner cavity of the product. We can't leave any dirt on the sealing ring and on the board surface. If there is no cleaning, we absolutely can not close the disc, otherwise it will cause serious damage to the sealing ring! And before we install the product is best to use the valve flange, such as socket steel flange parts of. The best electric butterfly valve installation method is the vertical installation method. Do not use the flip-chip mounting method. This requires our staff to pay more attention to the correct position of the product installed in the pipeline when installing the product. Normative. When in use, the flow needs to be adjusted. If there is a turbine box, we should also exercise proper control.
For some electric butterfly valves with relatively frequent opening and closing times, the lid is opened after two months of use. To see whether the butter inside the product is normal, if the amount is relatively small, it should be Add butter, otherwise it will adversely affect the quality of its work. If it is found that the position of the valve stem is not flexible or that its sealability is not so good, our maintenance personnel should focus on checking whether some of its parts are compressed. Without compression, it should be compressed again to ensure its tightness and its flexibility of rotation.
In the event of over-positioning and overstocking of the product's seals, we should check if there are any problems with the ends of the tubes. Using the outlet flange can help us solve the problem. For some repetitive valve stem electric butterfly valves, we should check the valve regularly, which can also facilitate us to timely check whether the product is faulty or not, and faults can be eliminated promptly.
