How to select materials for double flange pneumatic ball valves When using double flange pneumatic ball valves, they can be divided into single flange double flange pneumatic ball valves and double flange double flange pneumatic ball valves. When purchasing, we should first understand the knowledge of double flange pneumatic ball valves, and then after purchasing, we can improve the working efficiency when using them. Our company will introduce the industry knowledge of double flange pneumatic ball valve to you. The production of single flange double flange pneumatic ball valve is strictly made of high-strength carbon steel or stainless steel, and high-quality valves are used. The valve is sealed under the action of the gland and bolts by using the principle of compression elastic deformation of the valve.
The sealing ring shall be selected in strict accordance with the performance and user requirements. The single flange double flange pneumatic 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 pneumatic ball valve is used in water supply and drainage, sewage treatment and other industries, mainly 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 play a certain role in protecting the pipeline, especially providing great convenience for pipeline installation and maintenance. However, the double flange pneumatic ball valve shall be used at the pump outlet and the pipe corner, because the double flange pneumatic 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 caused by the thrust concentrated on the pipeline or the near end of the pump.
