[0016] Embodiments of the present utility model:

[0017] The utility model provides a portable control device for a single electric high-pressure throttle valve. Figure 1 and Figure 2, including a box body 1 and an electric high-pressure throttle valve 2, an analog controller 3 is provided in the box body 1, an analog setting key 4 is provided on the analog controller 3, a load switch 5, an opening increase button 6, an opening decrease button 7, a power interface 8 and a control interface 9 are provided on the box body 1, the load switch 5, the opening increase button 6, the opening decrease button 7, the power interface 8 are respectively connected to the control interface 9 signal, the power interface 8 is connected to the external power supply to power the analog controller 3 and the electric high-pressure throttle valve 2, the box body 1 is provided with A rotatable cable spool 10 is provided, on which an armored cable 11 is wound. The length of the armored cable 11 can reach 50 meters or even longer, and can be remotely connected to the electric high-pressure throttle valve 2. The electric high-pressure throttle valve 2 is provided with an electric actuator 12, and the electric actuator 12 is provided with an actuator control interface 13. One end of the armored cable 11 is connected to the control interface 9, and the other end of the armored cable 11 is connected to the actuator control interface 13. The control interface 9 is connected to the analog controller 3 by signal.

[0018] Preferably, the cable spool 10 is arranged at the lower part of the box 1.

[0019] Preferably, the armored cable 11 has both conductive and signal transmission functions, and only one cable is needed to achieve the conductive and signal transmission functions. The armored cable 11 conducts electricity to the electric high-voltage throttle valve 2 and realizes signal transmission between the control interface 9 and the electric high-voltage throttle valve 2.

[0020] Preferably, a power indicator light 14 is provided on the box body 1 .

[0021] Preferably, a valve position signal indicator light 15 is provided on the box body 1 , and the valve position signal indicator light 15 is in signal communication with the control interface 9 .

[0022] Preferably, a carrying handle 16 is provided on the top of the box 1 to facilitate lifting and moving the box 1. An operator can manually lift it to the work site, quickly insert the explosion-proof plugs at both ends of an armored cable into the control interface 9 and the actuator control interface 13, and then turn on the power to use it, thereby reducing the number of personnel configuration and reducing installation time. It is safe, reliable, easy to move, and convenient for later maintenance.

[0023] When the portable control device for a single electric high-pressure throttle valve of the present invention is in use, the operator operates the remote control device in a safe area 50 meters away to control the electric high-pressure throttle valve 2 to open or close proportionally. The set value can be added or subtracted by pressing the analog setting key 4 on the analog controller 3. The valve position signal indicator light 15 displays the valve position signal accordingly. The analog controller 3 sets the analog value, which is converted into a current 4-20mA signal internally and given to the electric actuator 12 on the electric high-pressure throttle valve 2, corresponding to the 0-100% proportional opening of the electric high-pressure throttle valve 2. The electric actuator 12 feeds back the 4-20mA current signal in real time, and the analog signal is then fed back to the analog controller 3.

[0024] Specifically, when the analog controller 3 and the electric high-pressure throttle valve 2 are energized, the load switch 5 is turned on, the power indicator light 14 illuminates, and the opening increase button 6 or the opening decrease button 7 is pressed to open and close the electric high-pressure throttle valve 2. The analog controller 3 can be used to set the output analog 4-20mA current value by pressing the analog setting key 4 to control the electric high-pressure throttle valve 2 to the corresponding valve opening. When the opening is completed, the actual opening value is fed back to the analog controller 3, such as 100% open or 0% closed, and the corresponding indicator light of the valve position signal indicator 15 illuminates as a prompt.
