Pipeline ball valve maintenance and management techniques
1. Maintenance and management of the construction period
During the construction period of the ball scientific management and maintenance is very important in the construction of the equipment management in place, maintain science, not only can ensure safety, and can greatly reduce the construction and operational management of costs. Major should note the following aspects: ① to the correct method of handling the valve, the valve to avoid mechanical damage. When the valve lifting, lifting belt can not be tied to the stem or actuators lifting, otherwise it will cause the stem bending diameter valve seal failure and gearbox destruction; Continue reading “Maintenance and Troubleshooting for natural gas pipeline ball valves”
Application of advanced technology in the domestic large pipeline valve:all welded ball valve
Application of advanced technology in the domestic large pipeline valve
Overview
All rely on imports in the year 2000 China’s large-scale all-welded pipeline ball valves. Localization process of digestion, absorption and innovation through the use of modern advanced design techniques, such as reverse engineering, screening engineering, numerical analysis of finite element method, anti-breaking design, the design of anti-corrosion, low torque design and advanced manufacturing technology and technology and equipment, was a success.
Reverse engineering technology and its applications
The key technology of all-welded body pipeline ball valves (Figure 1) is the body welding, welding ball valve assembly is the last step, not heat-treated. Therefore, the development of free weld heat treatment after welding technology research, anti-Sum learn the foreign pipeline valve welding process with technology product localization shortcut.
