How to select materials for double flange electric ball valve in use? The double flange electric ball valve can be divided into single flange double flange electric ball valve and double flange double flange electric ball valve. When purchasing, we should first understand the knowledge of double flange electric ball valve, and then we can improve the working efficiency when using after purchasing. Our company will introduce the industry knowledge of double flange electric ball valve to you. The production of single flange double flange electric ball valve strictly uses high-strength carbon steel or stainless steel as the material selection, uses high-quality valves, uses the principle of valve compression elastic deformation, and seals under the action of the gland and bolts.
The sealing ring shall be selected in strict accordance with the performance and user requirements. The single flange double flange electric ball valve is suitable for connecting with the flange while welding with the pipeline. There is a certain gap between the body and the expansion pipe, so that it has a certain axial and radial displacement. It can effectively compensate and relieve the thrust of the pipeline and blind plate in the pipeline, and also facilitate the installation, maintenance and replacement of water pumps and valves, It is actually the most ideal supporting product in the pipeline installation and operation industry.
The single flange double flange electric ball valve is used in water supply and drainage, sewage treatment and other industries. It is mainly used for the connection between pumps, valves and pipelines. It has a certain multi-directional displacement effect in pipeline operation, can alleviate the thrust of blind plates in pipeline operation, and plays a certain role in protecting pipelines, especially providing great convenience for pipeline installation and maintenance. However, the double flange electric ball valve should be used at the pump outlet and the pipe corner, because the double flange electric ball valve can transmit the thrust of the blind plate when starting the pump to the pump and various parts of the pipeline through the valve bolt (i.e. the full screw bolt), so as to avoid the impact force damage to the equipment when the thrust is concentrated on the pipeline or the near end of the pump.
