      The air source ball valve opening and closing member (sphere) is driven by the valve stem and rotates around the axis of the air source ball valve. It can also be used for conditioning and handling of fluids. The hard-sealed V-type air source ball valve has a strong shear force between the V-shaped core and the metal seat of the hardfacing alloy, which is especially suitable for fiber-containing, A medium such as fine solid particles. The multi-ventilation source air source ball valve not only can flexibly control the confluence, splitting, and flow direction switching of the medium, but also can close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. According to the driving method, the air source air source ball valve is divided into: a pneumatic air source air source ball valve, an electric air source air source ball valve, and a manual air source air source ball valve. Characteristics of the air source air source ball valve: 1. Wear resistance; because the valve core of the hard seal air source air source ball valve is alloy steel spray welding, the sealing ring is alloy steel surfacing, Therefore, the hard seal air source ball valve does not wear too much when it is switched. (It has a hardness coefficient of 65-70): 2. Secondly, the sealing performance is good; because the sealing of the hard-sealed gas source ball valve is manual grinding, until the valve core and the sealing ring are completely compatible. So his sealing performance is solid. Third, the switch is light; because the bottom of the sealing ring of the hard-sealed gas source ball valve uses a spring to make the sealing ring and the valve core tightly hold together, so the switch is very strong when the external force exceeds the preload of the spring. light. 4. Long service life: It has been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people's daily life. Pneumatic air source air source ball valve structure is simple and compact, the seal is firm, the repair is convenient, the sealing surface and the spherical surface are often closed, not easily eroded by the medium, easy to operate and repair, suitable for water, solvent, acid and natural gas, etc. The general working medium is mainly used to cut off or connect the medium in the pipeline, and can also be used for conditioning and manipulation of the fluid.
