Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery monitoring technology, specifically to an online monitoring device for oil and gas recovery at gas stations. Background Technology

[0002] Monitoring of oil and gas recovery at gas stations is a key step in controlling oil and gas volatilization, reducing air pollution, and ensuring safety. It needs to cover core indicators such as the sealing performance, gas-liquid ratio, and adsorption efficiency of the oil and gas recovery system.

[0003] Common oil and gas recovery monitoring equipment has a relatively dispersed layout of its various functional detection devices, which cannot monitor two different flow rates within the same time interval, reducing data synchronization and detection accuracy. In addition, the equipment is large in size, making it inconvenient to move and operate. Protecting each detection device would greatly increase operating costs.

[0004] Now, an online monitoring device for oil and gas recovery at gas stations is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an online monitoring device for oil and gas recovery at gas stations, in order to solve the problem mentioned in the background art that the detection devices are scattered and cannot monitor two types of flow within the same time interval.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring device for oil and gas recovery at a gas station, comprising a housing, a mounting base fixedly connected to the bottom of the housing, a controller fixedly connected to the top of the housing, a first connecting pipe fixedly connected to the bottom of the housing, a first liquid inlet on the left side of the housing, a first liquid outlet on the right side of the housing, a gas flow meter and a liquid flow meter installed inside the first connecting pipe, a first connecting rod fixedly connected between the gas flow meter and the controller, a second connecting rod fixedly connected between the liquid flow meter and the controller, a display screen on the upper side of the front end of the housing, an operation button on the lower side of the front end of the housing, and an indicator light fixedly connected to the top of the housing.

[0007] As a further technical solution of this utility model, the first connecting pipe, the first liquid inlet, and the first liquid outlet are internally connected, the size of the gas flow meter matches the size of the first connecting pipe, and the size of the liquid flow meter matches the size of the first connecting pipe.

[0008] As a further technical solution of this utility model, the gas flow meter is electrically connected to the controller, and the liquid flow meter is electrically connected to the controller.

[0009] As a further technical solution of this utility model, a second connecting pipe is fixedly connected to the left side of the first liquid inlet, an insulation sleeve is sleeved on the outside of the second connecting pipe, a temperature bulb capillary tube is fixedly connected inside the insulation sleeve, a second liquid inlet is opened on the left side of the top of the insulation sleeve, and a second liquid outlet is opened on the right side of the top of the insulation sleeve.

[0010] As a further technical solution of this utility model, the second connecting pipe is internally connected to the first connecting pipe, and the left side of the second connecting pipe is connected to the oil outlet pipe of the oil gun.

[0011] As a further technical solution of this utility model, the second liquid inlet, the temperature bulb capillary tube, and the second liquid outlet are internally connected, and the inner side of the temperature bulb capillary tube is tightly fitted with the second connecting tube.

[0012] As a further technical solution of this utility model, a third connecting pipe is fixedly connected to the right side of the first liquid outlet, and a solenoid valve is installed inside the third connecting pipe.

[0013] As a further technical solution of this utility model, the right side of the third connecting pipe is connected to the oil pipe, and the solenoid valve is electrically connected to the controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the online monitoring equipment for oil and gas recovery at gas stations not only improves the synchronization and detection accuracy of data, but also ensures the stability and accuracy of detection results, and can immediately shut off the oil and gas entry channel when the detection results are abnormal;

[0015] (1) By setting up a first connecting pipe, a first liquid inlet, a first liquid outlet, a gas flow meter, a first connecting rod, a liquid flow meter, and a second connecting rod, when in use, oil and gas flow into the first connecting pipe through the recovery port of the refueling gun. The gas flow meter and the liquid flow meter are installed adjacent to each other inside the first connecting pipe. The gas flow meter and the liquid flow meter feed back the detection results to the controller. The controller processes the detection data in a timely manner and feeds it back through the display screen. The gas flow meter and the liquid flow meter are arranged adjacent to each other, thereby improving the synchronization of data and detection accuracy. When abnormal data occurs, the indicator light will give the staff a prompt.

[0016] (2) By setting a second connecting pipe, a heat insulation sleeve, a temperature bulb capillary tube, a second liquid inlet and a second liquid outlet, the temperature will affect the physical state of the oil and gas. In use, the second connecting pipe is fixedly connected to the left side of the first liquid inlet. By setting a temperature bulb capillary tube on the outside of the second connecting pipe, a temperature control medium is injected into the second liquid inlet. The temperature control medium passes through the temperature bulb capillary tube and is discharged from the second liquid outlet. The temperature bulb capillary tube is tightly attached to the second connecting pipe, thereby achieving effective control of the oil and gas temperature inside the second connecting pipe, thus ensuring the stability and accuracy of the detection results.

[0017] (3) By setting a third connecting pipe and a solenoid valve, when in use, the third connecting pipe is fixedly connected to the right side of the first liquid outlet. The right side of the third connecting pipe is connected to the recovery oil tank. When the detection result is abnormal, the controller starts the solenoid valve, thereby closing the oil and gas entry channel immediately to avoid safety risks. At the same time, gas station detection usually needs to be carried out during the refueling interval. If the abnormal detection is not terminated in time, it will occupy the refueling gun usage time. The detection personnel need to repeatedly check the data and troubleshoot the problem, which reduces the overall detection efficiency. Attached Figure Description

At the same time, a third connecting pipe 19 is fixedly connected to the right side of the first outlet 6. The right side of the third connecting pipe 19 is connected to the recovery oil tank. When the test results are abnormal, the controller 3 activates the solenoid valve 20, thereby immediately closing the oil and gas entry channel to avoid safety risks. In addition, gas station tests usually need to be carried out during refueling intervals. If abnormal tests are not terminated in time, it will occupy the refueling nozzle usage time, and the testing personnel will need to repeatedly check the data and troubleshoot the problem, reducing the overall testing efficiency.
