High platform ball valve installation

發(fā)布時間:2022-01-04瀏覽量:577

In recent years, the ball valve is a new type of valve that has been widely used. A high platform ball valve is a valve with a spherical closure that can change the flow direction of the medium. It needs to be installed correctly at the time of use, otherwise it will not work well. The installation operation of the high platform ball valve is as follows:


In the first step, remove the protective cover of the ball valve and let it be cleaned in an open state to keep it clean. The second step is to check according to the prescribed pre-warning gas or electricity before installation, and only after passing the line can the installation work. The third step is to clean the remaining impurities in the pipeline. The fourth step is to install the high platform ball valve in the horizontal or vertical direction of the pipeline, and some supports can be used to eliminate the deviation of the pipeline. The fifth step, after connecting and fixing the high platform ball valve and the pipeline, please use a specific standard torque to cross and tightly lock the flange connection bolts so that they cannot be offset or rotated.
