Fully welded ball valve
Welded ball valves are widely used in various fields. Their superior quality and performance stability can not be achieved by ordinary cast steel ball valves. The service life of all welded ball valves is much longer than that of cast steel ball valves. All welded ball valves are widely used in urban gas, urban heating, petrochemical industry, shipbuilding, steel, pressure regulating station, power plant and other pipeline equipment.The welded ball valve adopts elastic sealing structure, with reliable sealing and easy opening and closing. The valve rod adopts a bottom mounted structure with inverted seal. When the valve chamber is abnormally pressurized, the valve rod will not be rushed out. Ball valves are widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions requiring strict cut-off. Driving mode: 90 ° switch positioning mechanism can be set manually, electrically and pneumatically, and locked as required to prevent misoperation.
All welded ball valve, no external leakage and other phenomena. The machining process of the sphere is tracked and detected by advanced computer detector, so the machining accuracy of the sphere is high. As the material of the valve body is the same as that of the pipeline, there will be no uneven stress, no deformation due to earthquake and vehicles passing through the ground, and the pipeline is resistant to aging. The seal ring body is made of rptfe with 25% carbon to ensure no leakage (0%). The directly buried welded ball valve can be directly buried underground without building a high and large valve well. It only needs to set a small shallow well on the ground, which greatly saves the construction cost and engineering time. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline. The machining accuracy of the sphere is very precise, the operation is light, and there is no bad interference. The use of advanced raw materials can ensure the pressure above PN25. Compared with products of the same specification in similar industries, the valve body is small and beautiful. Under the condition of ensuring the normal operation and use of the valve, the service life is more than 20 years.
