[ China Instrument Network Instrument Development ] On November 16, 2018, Gansu Provincial Industrial and Commercial Committee organized the “Desulfurization and Denitration Knife Type Gate Valve, Internal Heating Type Liquefied Detachable Ball Valve, and Two-Way Sealed Nickel Base Specially Developed by Lanzhou High Pressure Valve Co., Ltd. Alloy special cut-off valve" identification meeting. Song Yinli, Secretary General of China Valve Association, Yu Shurong of Lanzhou University of Technology, Lanzhou Petrochemical, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Provincial Machinery Science Research Institute, Gansu Yinguang Chemical Group and other experts attended the appraisal meeting.
At the appraisal meeting, the technical director of Langao Valve, Yao Yaogui, reported to the experts on the technology, functions and applications of the three new products one by one:
The desulfurization and denitration knife type gate valve is used in pipelines containing dust, slurry and other working conditions such as petroleum, chemical, electric power, etc., and is designed with innovative structures such as immovable gaskets, flushing angles, and push rods that can adjust the sealing ability online. It has the characteristics of strict sealing and corrosion resistance. After industrial operation, the effect is outstanding, which has made significant contributions to the realization of the national blue sky project.
The internal heating type liquefied gas special cutting ball valve is a valve developed by Lanzhou High Pressure Valve Co., Ltd. for Maoming Petrochemical liquefied gas pipeline. It is used in pairs upstream and downstream of the liquefaction pump. It is designed with a unique sealing structure and uses a heat source capable of circulating flow. The hidden danger of icing on the sealing surface is solved, and the liquefaction pump is repaired quickly, conveniently and safely.
The two-way sealing nickel-based special alloy special cut-off valve is used in a chemical company phenyl phosphorus chemical project. The high temperature, high corrosion, high erosion and solid particles are the typical environment for the service of this valve. The ordinary valve has a short life and serious. Affects production efficiency. In response to this harsh working condition, the company organized a research team to conduct in-depth exploration from materials and structures, and formed a suitable technical solution. After industrial application, it exceeded expectations. After disintegration inspection, the structure was intact, and there were no signs of corrosion or erosion. , won the trust of users.
For the three new products, the participating experts carefully questioned the working conditions of the products, structural plans, materials selection, process, enterprise standard formulation of new products and industrial operation of the products. After careful deliberation, the experts at the meeting agreed that Lanzhou High Pressure Valve Co., Ltd. independently developed the "two-way sealing nickel-based special alloy special shut-off valve, desulfurization and denitration knife type gate valve, and internal heating type liquefaction special cutting ball valve", which is innovative in filling the structure design. The domestic gap has reached the domestic leading level.
During the meeting, the leaders of Gansu Provincial Industry and Information Technology Committee and the experts fully affirmed the achievements of Lanco Valve in technological innovation and the successful development of the three products. It is recommended to speed up the promotion and application. Praising the Lanco valve from Chinese manufacturing to Chinese creation is a model of innovation-driven development.

1. Double beam bridge crane is the first to create honeycomb beam design, which is characterized by light deadweight, large load, strong wind resistance, etc.
2. The unique steel pin connection is not only firm and reliable, but also short in assembly time.
3. Flexible rod outrigger, which can be disassembled into single pieces when turning on site, and is convenient for transportation.
4. The minimum installed capacity solves the difficulty of field construction electricity
