[0005] Most crude oil delivery flow control devices include a body, in which a float is arranged and the liquid buoyancy of the float is used to control the oil output from the oil outlet pipe. However, the use of liquid buoyancy to control the output of the entire crude oil leads to poor control accuracy of the entire device due to the fluidity of the liquid itself.

[0006] In view of this, we propose a crude oil delivery flow control device. Utility Model Content

[0023] Most crude oil delivery flow control devices include a body, in which a float is arranged and the liquid buoyancy of the float is used to control the oil output from the oil outlet pipe. However, the use of liquid buoyancy to control the output of the entire crude oil leads to poor control accuracy of the entire device due to the fluidity of the liquid itself. The device can only be roughly controlled within a range and cannot be maintained within a precise range.

[0024] like Figure 1-Figure 3 As shown, this embodiment provides a crude oil delivery flow control device, including an oil pipe 100 and a control component 200. The control component 200 is arranged in the oil pipe 100. Considering the detection of oil speed, the control component 200 includes a closing block 201 and a pressure detector 204. The pressure detector 204 uses a ZCH204AA flat-plate pressure sensor. The closing block 201 is arranged in the oil pipe 100 and closes the oil pipe 100. When crude oil passes through the oil pipe 100, the closing block 201 is squeezed to move the closing block 201 upward. The pressure detector 204 is arranged above the closing block 201, so that the oil speed is judged according to the data of the pressure detector 204. A control rod 206 is provided above the closing block 201.

[0025] The improvement of this embodiment lies in that: by arranging a control component 200 in the oil pipe 100, when oil flows in the oil pipe 100, the oil squeezes the closing block 201 in the control component 200, causing the closing block 201 to rise, thereby opening the oil pipe 100; by arranging a pressure detector 204 in the oil pipe 100, when the closing block 201 rises, the pressure detector 204 detects the pressure of the closing block 201 on the pressure detector 204; when the oil supply remains stable, the position of the closing block 201 is fixed by fixing the control rod 206, thereby further limiting the speed at which the oil passes.

[0026] In order to limit the moving direction of the closing block 201 and facilitate fixing the control rod 206 , the second embodiment of the present utility model is shown.

[0027] The oil pipe 100 includes a pipe body 101, a mounting shell 102 is provided above the pipe body 101, a control component 200 is provided in the mounting shell 102, a pressure detector 204 is symmetrically arranged at the top of the inner cavity of the mounting shell 102, a spring 203 is provided between the pressure detector 204 and the closing block 201, a data display 205 is provided on the side of the pressure detector 204 away from the inner cavity of the mounting shell 102, when the closing block 201 rises, the pressure is transmitted to the pressure detector 204 through the deformation of the spring 203, a control rod 206 passes through the top center of the mounting shell 102, and the control rod 206 is symmetrically provided with a plurality of groups of equidistant jacks, when the oil supply remains stable, the position of the closing block 201 is fixed by fixing the plug rod in the jack of the control rod 206, and the flow rate of the oil is limited, a slide groove 103 is provided in the mounting shell 102, a slider 202 is provided on the top of the closing block 201, and the slider 202 is slidably connected in the slide groove 103 to limit the sliding direction of the closing block 201.

[0028] In summary, the working principle of this solution is as follows:

[0029] When oil is supplied into the tube body 101, the oil squeezes the closing block 201, causing the closing block 201 to slide and rise under pressure in the slide groove 103 of the mounting shell 102. When the closing block 201 rises, the spring 203 is compressed and transmits the pressure to the pressure detector 204 at one end of the spring 203. The pressure detector 204 senses the force of the spring 203 and transmits the signal to the display 205 for data display. When the oil supply remains stable but the oil flow rate needs to be changed, since the value of the pressure detector 204 is proportional to the oil flow rate, the position of the closing block 201 in the tube body 101 is controlled by moving the control rod 206, the value of the pressure detector 204 is observed, the oil flow rate is determined, and the plug rod is fixed in the plug hole of the control rod 206 to fix the position of the closing block 201 in the tube body 101.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
