The Flanged Eccentric Butterfly Valve occupies a relatively important position in our production and life. The leakage of the Flanged Eccentric Butterfly Valve will have a significant impact on our production and life. The light will affect our production progress, and the serious will bring us immeasurable Loss. Therefore, the leakage of the Flanged Eccentric Butterfly Valve cannot be careless.

There are two reasons for the leakage of Flanged Eccentric Butterfly Valve. One is that the casting quality of the valve itself is not good enough, but this situation is very individual. As long as we choose to cooperate with high-quality butterfly valve manufacturers when purchasing, we can avoid it. The other is caused by the failure of the sealing pair. In our actual work, how to effectively prevent the leakage of the Flanged Eccentric Butterfly Valve?
1. Standardization of the design content of the Flanged Eccentric Butterfly Valve: When the design is selected, a valve specification including the design temperature, pressure, medium properties and state, as well as the valve type, valve body and main internal parts materials, and connection requirements are issued. This is not only It is conducive to the selection of design, and can also help purchasers in the selection of butterfly valves.
2. Use the correct method to operate the Flanged Eccentric Butterfly Valve: One-way butterfly valves cannot be used in pipelines with two-way flow. Operate correctly according to the drive form of the butterfly valve, and operate strictly in accordance with the operating instructions. The operation of the manual butterfly valve requires the operator to hold the handle or handwheel to operate it, and it cannot be opened and closed with the help of a lever or a long wrench. The operation of electric butterfly valve and pneumatic butterfly valve should follow the instructions and operate the actuator correctly. Wrong operation of the butterfly valve will not only damage the sealing surface of the valve, but also cause deformation of the valve stem.
3. Flanged Eccentric Butterfly Valve standard installation method: install the butterfly valve in strict accordance with the installation instructions of the butterfly valve, and keep the pipeline and the valve body clean before installation. If this is ignored, impurities will damage the sealing surface of the butterfly valve and affect the sealing performance of the butterfly valve. . There are no lifting points for horizontally installed electric valves and pneumatic valves; no matter it is a butterfly valve or other valves, do not install it upside down, so as not to build up debris on the valve cover and affect the sealing of the packing.
With the improvement of modern Flanged Eccentric Butterfly Valve production technology and the improvement of valve detection methods, as long as the above work is done well, leakage can be avoided to a certain extent. In addition, it is necessary to do a good job in the maintenance of the butterfly valve, and to repair and replace the valve that has problems in time, which can greatly reduce the frequency of leakage accidents.
