BI-DIRECTIONAL SEALING VALVE TECHNOLOGY SEMINAR FOR WATER SYSTEM

The bi-direction sealing valve technical seminar for water system, hosted by HENAN QUANSHUN FLOW CONTROL SCIENCE & TECHNOLOGY CO., LTD, assisted by LANZHOU UNIVERSITY OF TECHNOLOGY, was hold at Luoyang city From 28^th to 30^th October, 2016.  Luoyang city ,as ancient capital for thirteen dynasties, is an international place of interest .More than forty experts from many famous design institutes took part in the technical seminar .  Such as Northwest Electric Power Design Institute Co., Ltd, East China Engineering Science and Technology Co., Ltd, Beijing Huafu Engineering Co., Ltd, China Petroleum Langfang Pipeline Bureau, Liaoning Electric Power Survey and Design Institute, China Chengda Engineering Co., Ltd, Luoyang Ruize Petrochemical Design Institute, Shanxi Yanchang Petroleum Xinghua Chemical Co., Ltd, Shandong Haicheng Design Institute, Anhui Chemical Design Institute, Anhui Electric Power Design Institute, Changling Refining and Chemical Yueyang Engineering Design Co., Ltd, Nanjing Jinling Petrochemical engineering Design Institute, Shandong Electric Power Engineering Consultation Co., Ltd, Hebei Electric Power Design Institute, Heilongjiang Electric Power Survey and Design Institute, Henan Town and Country Planning Design Institute, CINF Engineering Corporation Limited and so on .

On 28th, October, the seminar prelude was pull open, all participants singed in and all conference staff took their place to welcome the experts coming from all over the country.

In the morning of 29th, October, the technical seminar of bi-direction sealing valve for water system was began in due form. Firstly, Mr Hong Mouqu, as vice –president of Henan Qunahun Flow Control Science & Technology Co., Ltd , made an opening speech, congratulated beforehand on the meeting .

Mr Ma Xinwei, the marketing director of Henan Quanshun Flow Control Science &Technology Co., Ltd, introduced QUANSHUN GROUP’s comprehensive strength to experts on site. Especially, HENAN QUANSHUN FLOW CONTROL SCIENCE &TECHNOLOGY CO., LTD, as the host for this seminar, has A1 grade pressure piping production certificate issued by nation, and international certificates of API, CE, ISO, etc. No matter the qualification or the strength, high awareness is enjoyed by the industrial valve line .

Mr Wang Fujun, the technical director of HENAN QUANSHUN FLOW CONTROL SCIENCE &TECHNOLOGY CO., LTD, introduced the R&D back ground , structural features and application status analysis for water system of bi-direction sealing rotating ball valve and double eccentric semi-ball valve to all experts on the conference.

Zhang Xiheng , as professor in Petroleum Chemical Engineering Institute of Lanzhou University of Technology, has abundant teaching experiences and senior attainments on the field of valve theoretical research.

Professor Zhang xiheng analyzed the structural features of semi-ball valve and rotating ball valve. He use calculus to calculate the semi-ball valve’s flow area, and employ flow dynamic field three-dimensional finite element software ANSYS to analyze the rotating ball valve’s flow field, body strength and deformation analysis; He prove the rotating ball valve’s peculiarity of structural design in principle and theory, the technical problem for bi-directional sealing in the field of this valve is overcame.

Professor Zhang brought profound academic theory and wonderful valve structure explaining, all attendees listened attentively and immersed in the place of knowledge.

Subsequently, it is time to tea break .All people took group photo to mark the occasion. Brilliant smile on every one’s face looked like the sunshine out of the window, and lighted their heart.

Mr Wei Yongping, as engineer of Shanxi Yanchang Petroleum Xinghua Chemical Co., Ltd, has decades of working experiences about chemical plant, he shared the problem during the process of valve’s application at plant. In the past, for circulating water system and heat supply network system, corrosion and crystalline polamer very serious because of the flow with particle. Even if triple eccentric valve is used, but valve inside leakage happened and be serious, which take trouble for maintenance. Recently, bi-directional sealing rotating ball valve was adopted by design institute’s recommendation, up to now, more than forties valves from DN250-DN2200 have been used, less trouble happened, which greatly reduced the enterprise’s cost.  Good service from QUANSHUN VALVE CORP took everyone strong impression, so the words “ good service is the guarantee of cooperation” has been put forwarded .

After that , experts participate in the conference begun warmly discussion about the valve application and problems. The communicating contents not only  included material selection, valve installation size, valve structure, performance analysis, field installation, but also competitive advantage with other valves and so on.  All the discussed questions have been recorded by the related conference staff .

Lastly, Mr Meng Jianwei, as deputy general manager of Henan Quanshun Flow Control Science& Technology Co., Ltd, made detailed answer and professional explaining for all problems gathered.

On the morning of 30th, October, all experts came to HENAN QUANSHUN FLOW CONTROL SCIENCE & TECHNOLOGY CO., LTD.  Mr Wu Shuilin, the deputy director of QUANSHUN GROUP, welcomed everyone at the gate.

All experts came to our shop for visiting by the guiding of Mr Meng Jianwei, deputy general manager of QUANSHUN FLOW CONTROL, the raw material control of semi-ball valve, rotating ball valve, machining process, assembling procedure, pressure test and so one all aroused strong interesting from the experts on site, they listened to Mr Meng Jianwei’s detailed explaining, discussed the valve and their processing technic, meanwhile took photos time and again.

Via this seminar, all experts show high appreciation for QUANSHUN FLOW CONTROL COMPANY’s technical innovation, and show keen interest and high-level endorsement for the excellent performance of eccentric semi-ball valve and bi-directional sealing rotating ball valve, as well as showed that they will recommend and select QUANSHUN valve in the project designing process.
