First of all, the chemical stability of the fluorine valve makes the non electric ball valve have excellent performance. Some foreign non electric ball valve manufacturers even clearly pointed out in the data of the non electric ball valve that the fluorine valve can only be used to make the expansion joint of the non electric ball valve when the medium of the power plant contains S02., S03, etc. We provide a large number of non electric ball valves for the power industry. Practice has proved that the expansion joint of non electric ball valves is suitable for the use of fluorine valves in power plants.
The electric ball valve will encounter different installation environments during installation. These external factors have certain requirements for the layout and laying of the electric ball valve. In order to reduce unnecessary troubles in the layout and laying of the electric ball valve, the following explains the aspects that should be paid attention to in the layout and laying of the electric ball valve.
(1) As soil is a good thermal insulation material, the deeper the buried pipe is, the higher the shell temperature and soil temperature field will be. Therefore, shallow burial is favorable for direct burial of steam pipes.
(2) In order to ensure the reliability of the compensation link, the design span should not be more than 100m, and the compensation amount should not be more than 200m, but the design span should not be too small to avoid increasing the pipeline investment. In addition, the fixed support and the electric ball valve are weak links, and poor treatment will affect the service life of the entire pipeline. In addition, electric ball valve or fixed support shall be set at the change of diameter and pipe wall thickness, and the fixed support shall be set at the side with larger pipe wall thickness.
