Recently, the world's highest solar thermal power station, the Tibet Zabuye Source-Grid-Load-Storage Integrated Energy Supply Project, was successfully connected to the grid for power generation, marking another solid step in the field of plateau clean energy in China. Located in Zabuye, Tibet, in the hinterland of the Qinghai-Tibet Plateau, with an altitude of 4,500 meters, the project is the world's first power station to achieve clean energy operation at such a high altitude and at the end of the grid. After the project is officially put into operation, it will provide safe, stable and green electricity for the local area and contribute to the sustainable development of the regional economy and society.
ReadIn the field of high-end equipment manufacturing, the safety and reliability of valves are directly related to the stability and efficiency of the project. As a pioneer in China's valve industry, Lianggu Valve Group has always taken "making good valves for the world" as its mission, continued to innovate and keep improving. This time, Lianggu pneumatic high-temperature and high-pressure control valve was successfully applied to the 100,000-kilowatt molten salt tower solar thermal power generation project of Hainan Qingyu DC Phase II of Qinghai Company. When the Gobi sunshine turns into thousands of lights, Lianggu's products guard the "temperature of light" at the national CSP station at an altitude of 3,000 meters and contribute to the cause of clean energy.
Spring is deep and warm, and everything is competing. On the occasion of the International Labor Day, Lianggu Valve Group would like to extend holiday greetings and high respect to the colleagues who are fighting in various positions!
With the development of China's coal chemical industry and natural gas liquefaction industry, the localization of key equipment required is gradually deepening. Although the 100,000 cubic meter air separation unit was successfully used in Shenhua Ning Coal, a large number of large-scale air separation units and LNG-equipped cryogenic pump valves have been imported for a long time. To this end, the China General Machinery Industry Association held a seminar in Beijing on November 17, inviting relevant leaders and experts from Hangzhou Oxygen Group and Sichuan Air Separation Group to introduce the market of air separation units and natural gas liquefaction units for pump valves. Requirements and technical requirements, and discuss with the technical leaders of the pump and valve companies present at the meeting.

Wenzhou City, Zhejiang Province encourages industry associations to participate in quality co-governance to promote industrial quality improvement
Just in November, Zhejiang Quality Supervision Bureau successively held two quality comparison conferences. In these two quality comparisons, the relevant industry associations in Wenzhou were active organizers. The Longwan District Electrical Appliances Association assisted in organizing and implementing the quality comparison activities of indoor lighting switches, and the Yueqing Circuit Breaker Association assisted in organizing and implementing the quality comparison activities of small circuit breakers. The relevant person in charge of the Supervision Department of the Zhejiang Provincial Quality Supervision Bureau said that because of the active participation of industry associations, the number of companies participating in the comparison was greater than before, and the results of the comparison in the industry were more efficient than before.
On November 30th, the “Valve Certification Testing Seminar” co-organized by Zhejiang Pump and Valve Industry Association and jointly sponsored by Zhejiang Xinhai Testing Co., Ltd., Jiangsu Rongda Material Corrosion Testing Co., Ltd., and TüV SüD Nande Certification Testing China Co., Ltd. Herman Hotel successfully held! Chen Wenrong, Secretary General of Zhejiang Pump and Valve Industry Association, Secretary General of Zhejiang Valve Standardization Committee, Zhang Xiaozhong, Executive Vice President of Zhejiang Pump and Valve Industry Association, Professor Wu Baizhong, Deputy Secretary-General of Wenzhou Mechanical Engineering Society, Director of the Valve Department of Wen Vocational College, Dong Jinxin, and Yongjia Pump and Valve Technology Center Director Chen Guoshun attended the seminar.
ReadOn November 29, the Global Excellence Conference and the 17th National Pursuit of Excellence Conference, jointly organized by the China Quality Association and the European Quality Management Foundation, were held in Beijing. At the meeting, China Quality Association announced the evaluation results of the 17th National Quality Award, and 39 organizations and projects won awards. 3 companies and 1 project in the petroleum and chemical industry won awards.
Ball valve (ball valve), a valve that is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal valve seat of the hardfacing. It is especially suitable for fibers and small solid particles And other media. The multi-port ball valve can not only flexibly control the confluence, divergence, and flow direction of the medium on the pipeline, but also can close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.
The gate valve is a gate of the opening and closing piece. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel and so on. The gate has rigid gate and elastic gate. According to the different gates, the gate valve is divided into rigid gate valve and elastic gate valve.
