Pneumatic pneumatic - valve The installation of pneumatic valve pneumatic control principle

pneumatic regulating pneumatic valve working principle: pneumatic control pneumatic valve is compressed air as power source, the cylinder as actuator, and with the aid of electric pneumatic valve positioner, converters, solenoid pneumatic valve, pneumatic valve for attachment to drive the pneumatic valve, realize the switch quantity or proportion type adjustment, industrial automation control system receives the control signal to complete conditioning pipeline medium: flow, pressure, temperature and other process parameters. Pneumatic control valve is to control the characteristics of simple, quick response, and intrinsically safe, do not need another explosion protection measures. Structure classification: according to the pneumatic valve action pattern can be divided into: straight stroke and stroke in two ways. The characteristics of the pneumatic control valve, control simple quick response intrinsically safe, do not need another explosion protection measures. Pneumatic regulating principle of pneumatic valve installation: ( Pneumatic control valve installation position, the request has the certain high pneumatic valve from ground up, down to have a certain space, degrees, and the upper and lower of pneumatic valve must be reserved space, pneumatic valve for disassembling and repairing. Disassembling and repairing. For equipped with pneumatic pneumatic valve positioner and regulating pneumatic valve handwheel, must ensure that the operation, observation and easy to adjust. ( Regulating pneumatic valve should be installed in horizontal pipe runs, and pipeline hang them up and down generally want to support under the pneumatic valve, to ensure stable and reliable. Straight, will make the pneumatic valve to support, to ensure stable and reliable. For special occasions, in special cases, need to adjust the level of pneumatic valve installed on the vertical pipe, also should adjust the pneumatic valve support ( Road, also should adjust the pneumatic valve support ( Small diameter except pneumatic valve adjustment. When installation, to avoid to bring additional stress to the regulating pneumatic valve,. ( Regulate the temperature of a pneumatic valve working environment in ( - ~ + regulating pneumatic valve working environment temperature in ( - ~ ( - relative humidity is no more than % %. ℃, relative humidity is no more than %. ( Regulation before and after pneumatic valve position should be straight pipe, pneumatic valve straight pipe before and after regulating pneumatic valve position should be straight pipe before and after, length is not smaller than the pipe diameter (The Times D, times the pipe diameter, to avoid length is not smaller than the pipe diameter (The Times D, in order to avoid pneumatic valve straight pipe is too short and affect the flow characteristic. ( Adjust the caliber of pneumatic valve and pipe is not at the same time, reducing pipe connection should be adopted. When small regulating pneumatic valve installed, available threaded connections. Pipe connection. When small regulating pneumatic valve installed, available threaded connections. Pneumatic fluid direction arrow on the valve body shall be consistent with the direction of flow. Pneumatic fluid direction arrow on the valve body shall be consistent with the direction of flow. To set up the by-pass pipe. ( To set up the by-pass pipe. Purpose is to facilitate switching or manual operation, can be adjusted without stopping the pneumatic valve for maintenance. Can be adjusted without stopping the pneumatic valve for maintenance. ( Adjust the pneumatic valve before installation to thoroughly remove foreign bodies in the piping, such as dirt, slag, etc.
