Three kinds of valve products developed by Jiangsu Su Salt Valve passed the national appraisal

In the afternoon of December 2nd, China General Machinery Industry Association organized the LZ943WF-900LB-24 "Adjustable plate gate valve, 24" FLJ941H900LB high pressure throttling developed by Jiangsu Suyan Valve Machinery Co., Ltd. in Binhai, Jiangsu. Three kinds of new product prototype meeting for air vent valve and wellhead with dark-rod flat gate valve were identified. Experts of the appraisal committee heard the report of the development summary, the expert witnessed the report, and consulted relevant design, manufacturing, testing, inspection and other documents, and examined At the scene of manufacturing and testing, the three nationally-produced valves were approved by the state-level new product. All three new products have filled domestic gaps and reached advanced levels at home and abroad. For this reason, new product certifications have been unanimously approved, and they can be put into batch production. The future market prospects are broad.

The appraisal meeting was presided over by Huang Jin, President of China General Machinery Industry Association, Yan Yongbin, honorary president of China General Machinery Industry Association, Song Yinli, deputy secretary-general of China General Machinery Industry Association and general secretary of valve branch, executive vice secretary general of Jiangsu Valve Industry Association, Sheng Genlin, and PetroChina. , Sinopec, Hefei Valve Research Institute, Jianghan Valve Research Institute, PetroChina Pipeline Company, West-East Gas Pipeline Engineering Co., Ltd., Lanzhou University of Technology, Daqing Oilfield Valve Inspection Center and other top industry experts, professors, leaders, etc. gathered to participate in the appraisal meeting.

The expert committee of the appraisal was chaired by Chief Expert Wang Jinfu of Sinopec Luoyang Engineering Co., Ltd., Zhang Baojiang Jiao Gao of Sinopec Engineering Construction Co., Ltd. Liu Hongfu Jiao Gao of PetroChina Huadong Design Institute Co., Ltd., Chen Zhongxi of Daqing Oilfield Design Institute, and West China Gas East China Petroleum Pipeline company Peng Rensha Jiao Gao, Lanzhou University of Technology Special Valve Technology Research Institute Professor Li Shuxun, Jianghan Machinery Institute Wen Zhixiong Director, Sinopec Ningbo Engineering Company Wang Lanxi Gao Gong, Daqing Oil Field Testing Center Zhu Bin, Hefei General Machinery Research Institute Hu Jun Gao Gong etc. Composition expert committee.

The innovation of the LZ943WF-900LB-24" modulating plate gate valve developed consistently by the expert appraisal committee for the development of the Suyan Salt Valve is mainly due to the development of a non-guiding ram plate structure, which has a scratch with the entire diversion gate plate in the closing process. The sealing surface, followed by the development of a two-way sealing surface structure for the valve seat and the gate seal, with reliable sealing and zero leakage, and a fully floating positioning gate for the gate, with accurate closing position. The innovations of the well-headed flat-plate gate valve developed mainly include the development of a new type of dark-rod gate structure, the absence of a valve stem through the hole on the gate plate, and the reduction in the thickness of the gate; a two-way spring-type universal plug seal ring was developed and used as a metal. With the soft seal method, the seal is reliable and the service life is long; the double valve seat seal structure is adopted, and on-line maintenance and replacement of the shutter are realized.
