Abstract
The utility model relates to a plastic pneumatic ball valve which comprises a pneumatic actuator (1), a connecting bracket (2) and a valve body (3). The connecting bracket (2) is centrally and fixedly installed at the upper end of the pneumatic actuator (1). The valve body (3) is fixedly arranged at the upper end of the connecting bracket (2). The valve core is arranged in the middle of the valve body (3). The valve core is connected with the vertically-installed valve rod. A coupling rod is positioned in the connection bracket (2). One end of the coupling rod is connected with the upper end of the pneumatic actuator (1) of a rotation shaft (17), and the other end is connected to the lower end of the valve rod. The plastic pneumatic ball valve has the advantages of being simple in structure light in weight, strong in corrosion resistance and wear resistance, easy to install and disassemble. The valve body and the valve core are both made of high strength plastics. The plastic pneumatic ball valve can be applied to a plurality of fields of sewage pipe systems, salt water and sea water piping systems, potential of hydrogen and chemical solution system fields.
