Huaxia Valve Localization Project Awards

On October 25, the 2015 China Machinery Industry Science and Technology Award was announced. 366 scientific and technological achievements won the 2015 China Machinery Industry Science and Technology Award. The localization of the key valves of the ultra (super)critical thermal power unit jointly developed by Huaxia Valve and Chongqing Hechuan Power Generation Co., Ltd. won the third prize.

It is reported that the China Machinery Industry Science and Technology Award is the highest industry award set by the China Machinery Industry Federation and the China Mechanical Engineering Society and approved by the Ministry of Science and Technology. The award is judged by an expert meeting and reviewed once a year.

Chongqing Hechuan Electric Power Co., Ltd. No. 3 unit (660MW ultra-supercritical) is the first batch of localization projects for the key valves of ultra-supercritical thermal power units identified by the National Energy Administration, and has undertaken all types of valves 281 sets, Type II valves. 59 units of practical application. In this project, Huaxia Valve Chief Research Institute Chen Xuefeng, Chen Rongchang, Peng Bo, Fei Tianwen and others paid attention to the product development of the early involvement of the OEM. According to customer requirements, according to the international development process, the world advanced engineering design analysis and test validation By means of timely development of new products that fully meet the needs of power plants, a series of technological innovations have been achieved.

According to statistics, Huaxia Valve provided 66 sets of Class I valves for broken gate valves, globe valves, and check valves for its No. 3 unit boiler island; steam pump outlets for No. 3 and No. 4 units provide high-pressure water supply piping systems. Eight sets of Type I valves for electric gate valves, high-output electric gate valves, and boiler water gate valves; 2 sets of boiler island water tank water level regulating valves for Type 2 key control valves for Unit 3 are provided. After more than two years of actual operation, Chongqing Hechuan Electric Power Co., Ltd. has confirmed that the localized products used in Unit 3 and Unit 4 (660MW ultra-supercritical) have been put into operation. The operation is flexible, the operation is safe and reliable, and various technical indicators have been achieved. The advanced level of imported similar valve products can replace the use of imported valves.
