Coal gasification process, the process characteristics of the medium three-phase flow of high temperature and high pressure, high flow rate of the valve body and valve parts erosion, cavitation and corrosion is more serious, leading to Blackwater of valve fault, short cycle, maintenance difficulties, become one of the coal chemical industry has been plagued by difficulties of user pain points. The rotary cylinder type angle Blackwater valve using a new design concept and patented technology, thoroughly break the traditional straight trip of Blackwater angle valve palliatives, the occurrence of the above problems to avoid from the structure, process and material on the. In 2016, the product was awarded the title of "good instrument in China" by China Instrument and meter Institute, and it was granted the national invention patent license on 2017, 05, 03 (patent number: ZL 2015 2 0203481.6).
