The compression strength and soft sealing performance of the project supporting single and double flange pneumatic ball valve. The supporting single and double flange pneumatic ball valve of the project is composed of loose sleeve pneumatic ball valve, short pipe flange, power transmission screw and other components, which can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. It is mainly used for loose sleeve connection of pump, valve, pipeline and other accessories. The single and double flange pneumatic ball valve for the project is made of high-strength carbon steel or stainless steel, high-quality valves, and sealed under the action of the gland and bolts based on the principle of compression elastic deformation of the valve. The sealing ring is selected in strict accordance with the use performance and user requirements.
The supporting single and double flange pneumatic ball valve of the project 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 supporting single and double flange pneumatic ball valve of the project 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, play a certain role in protecting pipelines, especially for the installation and maintenance of pipelines.
However, pneumatic ball valves should be used at the pump outlet and the pipe corner, because the 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 force transfer bolts (i.e. full screw bolts), so as to avoid the impact force damage of the thrust concentrated on the pipeline or the near end of the pump. Because this series of products are metal products, which have high tensile and compressive strength, superior soft sealing performance, convenient loading and unloading and other functions, they are frequently used in industries such as monthly power, metallurgical water supply and drainage, sewage treatment and so on. They are mainly used for the connection between pumps, valves and pipelines. They have a certain multi-directional displacement effect in pipeline operation, It can alleviate the thrust of blind plate during pipeline operation, and play a certain role in protecting the pipeline, especially providing great convenience for pipeline installation and maintenance. The production of single and double flange pneumatic ball valves for the project produced by Shanghai Luoying strictly uses high-strength carbon steel or stainless steel as the material selection, high-quality valves, the principle of compression elastic deformation of valves, the sealing under the action of the gland and bolts, and the sealing ring is selected in strict accordance with the use performance and user requirements.
