Embodiment 1
[0023] Such as Figure 1-3 As shown, a pressure reducing valve intelligent regulator, it includes a pressure reducing valve pilot valve 9, the top of the pressure reducing valve pilot valve 9 is installed with a mounting bracket 3, and the top of the mounting bracket 3 is equipped with a planetary gear reduction machine 2, the input shaft of the planetary gear reducer 2 is connected with the output shaft of the stepper motor 1, and transmits torque; the stepper motor 1 is connected with the stepper motor driver 8 through a control signal line, and the stepper motor The driver 8 is connected to the intelligent control module 4, and the signal input end of the intelligent control module 4 is respectively connected to the pressure reducing valve inlet pressure sensor 5 and the pressure reducing valve outlet pressure sensor 10 through signal lines. The output shaft of the planetary gear reducer 2 is connected with the pressure adjusting bolt 7 of the pressure reducing valve pilot ...
Embodiment 2
[0030] Such as Figure 4 , any control method of pressure reducing valve intelligent regulating device. When the device is working, the power supply module supplies power to the single chip microcomputer, stepper motor driver, pressure reducing valve inlet pressure sensor and pressure reducing valve outlet pressure sensor; the two pressure sensors are respectively Detect the pressure value of the inlet and outlet of the pressure reducing valve and convert the data into binary data through the AD module; the single-chip microcomputer reads the preset pressure value data stored in the EPROM, and detects whether the user needs to reset the pressure ; Then read the inlet and outlet pressure value data in the AD module, and then display the inlet and outlet pressure values and the set pressure value through the LCD screen; finally drive the stepping motor to move, and drive the pressure-reducing valve pilot valve pressure adjustment bolt to rotate and adjust Pressure relief valve...
