Problems solved by technology

When the inlet pressure of the pressure reducing valve or the flow rate of the outlet of the pressure reducing valve and the smoothness of the control system pipeline change, the outlet pressure of the pressure reducing valve will also change accordingly. The pressure reducing valve cannot maintain a constant outlet pressure and needs to be manually readjusted pressure

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...

Abstract

The invention discloses an intelligent adjusting device and method for the pressure of a reducing valve. The intelligent adjusting device comprises a reducing valve pilot valve. A mounting bracket ismounted on the top of the reducing valve pilot valve, a planetary gear reducer is mounted on the top of the mounting bracket, and an input shaft of the planetary gear reducer is connected with an output shaft of a stepping motor and transmits torque; the stepping motor is connected with a stepping motor driver through a control signal line, the stepping motor driver is connected with an intelligent control module, and the signal input end of the intelligent control module is connected with a reducing valve inlet pressure sensor and a reducing valve outlet pressure sensor through signal lines.The device is installed on the pilot valve of the traditional reducing valve through the bracket; by detecting the inlet pressure and the outlet pressure of the reducing valve and comparing the inletpressure and the outlet pressure with set pressure values, the stepping motor is driven to act to rotate a pressure adjusting bolt of the pilot valve, and thus automatic adjustment of the outlet pressure of the reducing valve can be intelligently achieved.

Description

technical field [0001] The invention belongs to the technical field of valve devices, in particular to a device and method for intelligently adjusting the pressure of a pressure reducing valve. Background technique [0002] The pilot-operated pressure reducing valve usually uses a pilot valve to control the outlet pressure of the pressure reducing valve, and the pressure is adjusted by manually rotating the pressure adjusting bolt of the pilot valve. When the inlet pressure of the pressure reducing valve or the flow rate of the outlet of the pressure reducing valve and the smoothness of the control system pipeline change, the outlet pressure of the pressure reducing valve will also change accordingly. The pressure reducing valve cannot maintain a constant outlet pressure and needs to be manually readjusted pressure. Contents of the invention [0003] The purpose of the present invention is to provide a pressure reducing valve intelligent pressure adjustment device and met...
