Lined fluorine ball valve installation work is not a simple matter, but also do a good job before the installation of preparatory work, there is a saying goes, in order to use the valve for a long time we must do a good job of installation. First, to confirm the preparation of the ball valve before installation 1, to ensure that the fluorine-fluorine ball valve installation position of the pipeline in the coaxial position, the pipeline should be kept parallel to the two flanges to confirm that the pipeline can withstand the weight of the valve itself, if it is found that the pipeline can not withstand the ball valve weight , The pipeline is equipped with appropriate support before installation. 2, confirm whether there are impurities in the pipeline, welding slag, etc., must purge the pipeline clean. 3, check the nameplate lined fluorocarbon valve, and the valve fully open all closed several times to confirm the valve to work properly, and then a comprehensive inspection of the valve details, to ensure that the valve intact. 4, remove the protective cover at both ends of the valve, check the valve body is clean, clean the body cavity, as the fluorine-filled ball valve sealing surface is spherical, even tiny debris may also cause sealing surface damage. Second, the ball valve installation 1, the flange bolts on the need for symmetry, one after another, even tighten. 2, if the valve to pneumatic, electric and other actuators, according to the instructions to complete the gas source, power supply installation. 3. Any section of the lined ball valve can be installed on the upstream side. The handle ball valve can be installed at any position of the pipeline. If the ball valve of the actuator (such as gear box, electric-pneumatic actuator) is configured, the valve must be installed vertically. Exit in a horizontal position. 4, the ball valve flange and pipe flange according to the pipeline design requirements installed gaskets. Third, check the ball valve installation 1, according to the pipeline pressure design requirements, pressure testing after the ball valve and pipe flange surface sealing performance. 2, After installation, start the ball valve open, close several times, should be flexible action, uniform force, the ball valve is working properly. The above describes the ball valve installation before and after the installation and the specific work to do the above work, the ball valve can be used normally, but also on the life of the fluorine-loaded ball valve play a role, in addition we have in the future The use of regular valve maintenance.
