(Summary description)Before 1965, China had no valve electric device products, let alone professional manufacturers. At that time, China's main valve users: electric power, petroleum, chemical industry, metallurgy, water supply and drainage and other industries. Due to the small scale of enterprises, low operating parameters and low automation level, most of them used manual valves, so only some large factories such as Liaoning Tieling valve factory, Shenyang high and medium pressure valve factory, Shanghai Valve Factory and Harbin boiler factory produced large valves, It is equipped with a simple device for opening and closing the valve driven by an ordinary motor to drive the worm gear box, so as to solve the difficulty that the valve cannot be pulled by manpower.   In the field of valve use, in order to open and close the large valve, people tied a long lever on the handwheel, which was lined up by several or more young men to push the valve to open or close like a push mill.     In October 1964, with the development of China's national economy, valve users continued to develop in the direction of high parameters, large-scale and automation. They had higher and higher requirements for valve product varieties, specifications, parameters and automation level, and the demand was increasing day by day. In this situation, in order to meet the needs of the development of China's valve industry, the first machinery department decided to establish a valve research office in the general machinery industry centralized Institute - General Machinery Research Institute to uniformly plan, design and study the development of China's valve industry.     After the establishment of the valve research office of the General Institute, it attached great importance to the research and development of valve electric device products. In January 1965, the valve Office of the General Institute appointed comrades Hong Miancheng and Li Wangshun to Tianjin for investigation and research, and decided to designate Tianjin No. 2 general machinery factory, which originally produced small autoclaves, as the first professional manufacturer of valve electric device in China. At the same time, it was decided to establish a joint design group for valve electric devices to carry out design work in Tianjin (History: joint design of valve electric devices for * * times in China). The joint design team is headed by Li Wangshun of General Machinery Research Institute, attended by Xu Yuxia and Yao Dingxiang of Beijing Design Institute of Ministry of chemical industry, Zhu Xiaoxian of Beijing Design Institute of Ministry of petroleum, Zhao Zhende of Fushun Design Institute of Ministry of petroleum, Xiang Meigen of General Machinery Research Institute, etc.     In the first half of 1965, the joint design group designed and completed the design task of valve electric device of type B, type C and type D with maximum operating torque of 1200nm. In December 1965, Tianjin No. 2 general machinery factory completed the trial production of valve electric devices of these three models.

Where is the ball valve applicable
Where
The ball valve has been washed by materials for a long time, resulting in friction, resulting in serious impact wear, which can not meet the normal production, and shorten the service life of the equipment. At present, wear-resistant materials, such as ceramic materials and polymer composites, are mostly used for ball valve wear, and meijiahua technology system is widely used. Polymer materials have superior adhesion and super wear resistance, which can safely solve the disadvantages of frequent wear of metals and ensure the normal production of enterprise equipment. Moreover, the unique ceramic materials and special surface enhancers in the materials make their wear resistance and physical impact resistance superior to any steel or even more than ceramic tiles in the worst dry grinding environment. The incompatibility between products and coal is an ideal material to prevent coal accumulation.
