Precautions for installation and maintenance of fluorine-lined globe valve

The fluorine-lined globe valve operated by handwheel and handle can be installed in any position of the pipeline. The handwheel, handle and Weidong mechanism are not allowed to be used for lifting. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body. The fluorine-lined globe valve, also known as the cut-off valve, is the most widely used valve. The reason why it is popular is that the friction between the sealing surfaces is small during the opening and closing process, it is more durable, the opening height is not large, and it is easy to manufacture. , easy maintenance, not only suitable for medium and low pressure, but also suitable for high pressure. Its closing principle is that relying on the pressure of the valve stem, the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the medium from flowing. The fluorine-lined globe valve only allows the medium to flow in one direction, and has directionality during installation. Its structural length is longer than that of the gate valve, and at the same time, the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
