The 3rd China International Fluid Machinery Exhibition and China International Valve Expo, which is recognized by China's valve industry as the most professional, largest and highest level in China, is held in Beijing Exhibition Hall for three days. More than 500 famous manufacturers at home and abroad. Participated in the event, dozens of well-known foreign companies from the United States, Germany, Japan, South Korea, Italy and other groups participated in the exhibition. In recent years, a large number of private enterprises that have played an important role in the field of fluid machinery manufacturing have also shown their new development in the exhibition.
Hundreds of valve users, design institutes and engineering company leaders and experts, representatives of the Japan Valve Association and the Korea Valve Association, the United States, and European exhibitors visited the exhibition.
Zhejiang Chaoda Valve Co., Ltd. has demonstrated the development history and latest scientific research achievements and achievements of more than 20 years, and has been recognized by many visitors. Chaoda's latest key new products - (QT341Y, QT347Y) special metal hard seal ball valve for medium, grey water, cinder and other media, (TX41Y, TX61Y) metal hard seal lift plug valve, (Z23Y, ZF63Y, ZF64Y, T68Y , T67Y, HQ62Y) Oilfield special high pressure valves were awarded gold, gold and silver medals by China General Machinery Industry Association and China General Machinery Industry Association Valve Branch.
The special metal hard sealing ball valve for mortar, gray water, cinder and other media can be well applied to high temperature, high pressure, hard solid particle working medium, and is suitable for medium which is easy to coke and easy to bond. At the same time, the surface spraying technology, high-efficiency grinding technology and industrial mass production technology of high-pressure large-diameter spheres are well solved. After the technology is inspected, a number of technologies have filled the domestic gap. Applied to China's largest coal-carbon energy enterprise - Shenhua Group's "key coal liquefaction key technology" national "863 Program" project (currently the world's largest demonstration plant for coal-to-liquids), Sinopec Nanjing Chemical Industry Co., Ltd., Shandong Hua Luhengsheng Chemical Co., Ltd. and Sinopec Jinan Branch and other large-scale complete projects and national key projects have stable quality and good results, and are well received by users.
When the metal hard seal lift plug valve is opened and closed, the cock is lifted first, the cock is separated from the seat sealing surface, and then the cock is rotated by 90° to open or close the valve. Since the cock is separated from the valve seat during the opening and closing process, the opening and closing of the valve is very easy, and the sealing surface is protected during the opening and closing process, and is not washed by the medium, the two-way sealing is tight and reliable, and the valve has a long service life. The lift plug valve has been widely used in petrochemical, metallurgical, electric power and other industries, and has achieved good results and passed the provincial scientific and technological achievements appraisal.
There are defects in the mud valve of traditional oilfield drilling: when the drilling platform moves, the mud begins to solidify, so that when the valve is closed, the ram blocks the mud in the groove of the valve body, so that the closing is not strict, causing mud leakage like a grinding wheel to wear the ram, generally Only used in two or three months, the oil mud valve developed by the company is not easy to damage within 3 years. The special regulating valve of the oil field makes the sealing surface with a pressure of only about 1 MPa when the valve is closed by high pressure, which solves the problem of leakage damage adjustment head and leaking medium leakage when the high pressure is closed, and improves the stability and safety of the valve opening and closing. The welding slag and other substances generated during the welding operation of the traditional gate valve are easy to pinch the sealing surface and the gate is not tight, resulting in leakage of the valve. The oilfield water injection/polymer special gate valve developed by the company solves this phenomenon, and the high hardness anti-pinch is selected. The damaged metal material guarantees the stability of the product and has been appreciated by users for many years. The traditional check valve has failed to seal after a period of use. The double-ball anti-scaling check valve developed by the company solves the problem of medium fouling and ensures the safety of the wellhead device of the high-pressure pumping station. The company's oilfield-specific high-pressure valve series is applied to projects such as Daqing and Shengli Oilfields with good results and is well received by users.
