In order to better use the American standard flanged ball valve and give full play to its performance, we need to check it in daily use. The inspection method will be introduced below.
The method of checking the American standard flanged ball valve is as follows:
1. When the valve seat and flanged ball valve are in operation, due to the infiltration of the medium, the inner and outer surfaces of the thread used for fixing the valve seat are easily eroded and the valve seat is loosened. Special attention should be paid during inspection. For valves operating under high pressure difference, it is also necessary to check whether the sealing surface of the valve seat is washed out.
2. The valve core, the valve core is the movable part of the pneumatic flanged ball valve during operation. It will be corroded by the medium, and the corrosion will be more serious. Therefore, it is necessary to carefully check whether the various parts of the valve core are eroded and worn, especially the high pressure. Under poor working conditions, the wear of the valve core is more serious, so pay more attention.
3. The inner wall of the valve body, for the American standard flanged ball valve used in high pressure difference and corrosive medium places, the inner wall of the valve body will often be impacted and eroded by the medium, so it is necessary to focus on checking its pressure resistance and corrosion resistance.
The above is the inspection method of the American standard flanged ball valve. You can learn about it. If you need a friend, you can consult our Changyi Valve Co., Ltd.
