Which quota is recommended for electric angle ball valve? Before installation, Zibo electric ball valve needs to detect pipeline equipment, which is an important industrial branch of the national industrial system. The electric ball valve is an important product of the system, and is the most powerful support and guarantee for aerospace, automobile, road, bridge, chemical industry and other industries. At present, China's pipeline equipment is in a period of rapid development and improvement, and has made great progress in basic technology, design and manufacturing processes, high-end technology and new function development. The development of electric ball valve benefits from this. Therefore, the key to grasp the trend of electric ball valve in the future is to closely follow the development pace of automation technology. Automation is also the focus of the development of electric ball valve in the future. Specific inspection requirements before installation of electric ball valve guided by experts
1. The materials, finished products, semi-finished products, accessories, appliances and equipment used for water supply of electric ball valves must have Chinese quality certification documents, and the specifications, models and performance test reports should comply with national technical standards or design requirements. Inspection and acceptance shall be carried out when entering the site, which shall be verified and confirmed by the engineer.
2. The electric ball valve must be used for the water supply pipeline passing through the foundation of the building, the outer wall of the basement, and the building with strict waterproof requirements.
3. The electric ball valve water supply pipeline shall not pass through expansion joints, seismic joints and settlement joints.
4: Before construction, pipe fittings and valves shall be tested, and the pressure rating shall not be less than 1.5 times of the working pressure of the pipeline. After materials enter the site and before pipe laying, the pipes and accessories shall be inspected, including written certificates and physical inspection.
5: It is strictly prohibited to throw or collide the electric ball valve pipes during transportation, loading, unloading and stacking. The laying of pipes can be carried out only after the groove inspection is qualified. Before laying pipes, pipes, fittings, etc., a visual inspection shall be carried out again. The electric ball valve of drainage pipes shall be supplied first, and the pipes and fittings found to have problems shall not be used.
