Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas pipeline detection, in particular to an oil and gas pipeline anti-leakage detection device based on pressure induction. Background Technique

[0002] When oil and gas resources are transported over a long distance for a long time, pipelines are usually used for transportation. Due to the large transportation pressure inside the pipeline, the pipeline is prone to leakage during long-term use. Therefore, routine inspections of the pipeline are required.

[0003] However, the structure of the existing pressure detection device for oil and gas pipelines is too single, and it can only complete the detection of the pressure of the oil pipeline. When the detected pressure exceeds the specified range, it cannot timely handle the detected pressure problem of the oil pipeline. It needs to be handled by the staff on site, which is prone to safety hazards. Secondly, when the oil and gas pipeline is connected to the corresponding valve, it is only connected and fixed by the flange in cooperation with bolts and nuts, resulting in poor stability and sealing performance after the oil and gas pipeline is connected to the corresponding valve. Summary of the Utility Model

[0004] In order to solve the problem that the existing pressure detection device for oil and gas pipelines cannot timely handle the detected pressure problem of the oil pipeline and needs to be handled by the staff on site, which is prone to safety hazards; the purpose of the utility model is to provide an oil and gas pipeline anti-leakage detection device based on pressure induction.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: an oil and gas pipeline anti-leakage detection device based on pressure induction, including a connecting pipe, one end of the connecting pipe is installed with an automatic valve, one end of the automatic valve is installed with an oil pipeline, a mounting member is fixedly installed on one side above the surface of the oil pipeline, a pressure sensor is detachably installed on the top surface of the mounting member, the pressure sensor includes a sensor, a pressure monitoring device is installed on one side of the pressure sensor above the oil pipeline, the output end of the sensor is connected to the input end of the pressure monitoring device, an alarm is fixedly installed in the middle of the top surface of the pressure monitoring device, the output end of the alarm is connected to the input end of the automatic valve, and the pressure sensor, the pressure monitoring device, the alarm and the automatic valve cooperate with each other.

[0006] Preferably, the automatic valve includes a valve body, and first flanges are fixedly installed at both ends of the valve body. Second flanges are fixedly installed at one ends of the connecting pipe and the oil pipeline adjacent to the automatic valve.

Positioning pins are symmetrically installed on both sides of the bottom surface of the first sealing sleeve, and the positioning pins are slidably inserted into the top surface of the second sealing sleeve.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0009] 1. In the present utility model, the pressure in the oil pipeline during oil transportation is detected in real time through a pressure sensor. When the monitored pressure value exceeds the specified range, the sensor of the pressure sensor transmits the detected data to the pressure monitoring device.
