由阜新矿务局兴隆煤矿和开滦煤炭科学研究所自动化研究室共同研制并试验成功的“电—气调节阀”从1971年6月开始在阜新矿务局兴隆煤矿主井1×4×2.5矸石绞车上进行了五个多月的工业性试验和八个多月的正式运转,从1972年1月至7月累计运行26240次。“电—气调节阀”已在8月21日—22日召开的提升机制动系统“电—气调节阀”初步(钅监)定座谈会上作了初步(钅监)定。
By the Fuxin Mining Bureau Xinglong Coal Mine and Kailuan Coal Research Institute of Automation Laboratory jointly developed and tested successfully “electric - gas control valve” from 1971 June began in Fuxin Mining Bureau Xinglong coal mine main shaft 1 × 4 × 2.5 The gangue winch was tested for more than five months in industrial production and formally operated for more than eight months. From January to July 1972, a total of 26,240 operations were carried out. The “electro-pneumatic control valve” has been preliminary (supervised) at a forum for preliminary discussion on the “electro-pneumatic control valve” of the brake system of lift hoists held from August 21 to August 22.
