What factors are related to the sealing performance of automatic butterfly valve

In fluid control systems, the sealing performance of automatic butterfly valves directly affects the stability and safety of the pipeline system. In order to ensure the normal operation of the system, we need to pay attention to the following aspects.
First of all, the contact surface between the valve seat and the butterfly plate is a key factor affecting the sealing performance. In order to ensure that the two can fit closely and form an effective sealing structure, we use wear-resistant and corrosion-resistant materials to make the valve seat and butterfly plate, and perform precision machining and surface treatment. In addition, the size and shape of the contact surfaces are carefully designed to accommodate different operating pressures and fluid media.
Secondly, the selection of sealing materials is crucial to the sealing performance of automatic butterfly valves. We choose materials with good elasticity and wear resistance to maintain a stable sealing effect during the rotation of the butterfly plate. Common sealing materials include rubber, polytetrafluoroethylene, etc., which have excellent sealing performance and chemical stability and can meet the needs of different working environments.
In addition, the sealing performance of automatic butterfly valves is also affected by the working environment. In harsh environments such as high temperature, high pressure, and corrosive media, sealing materials are prone to aging, deformation, and other problems, resulting in a decrease in sealing performance. Therefore, when selecting an automatic butterfly valve, we need to fully consider its working environment and medium characteristics, and choose products and sealing materials with excellent weather resistance and corrosion resistance.
In addition to the above factors, the sealing performance of automatic butterfly valves is also closely related to the operation and maintenance methods. Correct operation methods include avoiding excessive opening or closing of the butterfly valve, maintaining stable system pressure, etc., which helps to reduce wear and deformation of the sealing surface. At the same time, regular maintenance inspections are also key to maintaining sealing performance, including cleaning the valve seat and butterfly plate, replacing worn sealing materials, etc.
