Electric butterfly valve leaks five ways to help you solve the problem
When we use the electric butterfly valve, it is still relatively easy to cause leakage of the product. And the occurrence of this kind of situation is also sometimes unavoidable. So how can we solve this situation? Here is a detailed description of the solution. I believe they can give you some inspiration or help at a crucial moment.
Solution one: We can increase the use of sealed grease in our products. However, this situation is mostly directed to some electric butterfly valve bodies that have not used seal grease. If we use this product without using a sealed grease, it can increase the seal performance of the valve stem. Therefore, it is also a very necessary maintenance method and procedure for our staff to maintain the product at ordinary times.
Solution 2: Changing the flow direction can prevent the occurrence of leakage. We can set P2 at the end of the stem. If P is relatively large and P1 is relatively large, then if we want to seal P1, it will be significantly more than P2. So we need to make some changes to the flow. Place the P1 stem on the P2 end. If the pressure in the work environment is relatively large and the pressure difference is relatively large, this solution can be very effective. For example, using a bellows valve can consider the P2 seal.
Solution 3: We usually use the lens sealing method to solve the problem. The sealing between the cover of the upper and lower lids of the electric butterfly valve and the seal between the valve seats can be effectively solved by using a lens gasket sealing method. If we use a flat seal, in the high temperature state, the seal may be much worse and cause leakage, but using the lens pad can help us to achieve satisfactory results.
Solution 4: Add some double-layered and multi-layered mixed fillers. It can increase the number of gaskets in a sense. However, the use of this method is not very obvious. Therefore, it is not recommended here for everyone to use this method to solve the problem of leakage of the product.
In addition to the above several methods, we can replace the graphite filler. The use of graphite filler not only can increase the sealing performance of the electric butterfly valve, but also causes the leakage problem to occur, and its service life is longer. If other methods are useless, we can try to use this method.
