Automatic inspection and intelligent remote control petroleum and natural gas wellhead valve and method

Abstract

The invention provides an automatic inspection and intelligent remote control petroleum and natural gas wellhead valve and method. The automatic inspection and intelligent remote control petroleum andnatural gas wellhead valve comprises a valve body and a power supply module, wherein an annular steel ring is arranged at the joint of the valve body and a pipeline, pressure sensors are evenly arranged on the annular steel ring, the pressure sensors are connected with a node controller, the node controller controls a brake device of the valve through a relay, and the node controller is connectedwith a control terminal through a network or a satellite signal. According to the valve, equipment operation monitoring can be performed in real time, once leakage of oil, gas or other liquid and gasoccurs, a leakage signal is immediately captured, the leakage signal is transmitted to an upstream control end at the first time to be intelligently turned off, a warning lamp is turned on, and meanwhile leakage information and the position of a leakage source are sent to a far-end management end; and all-weather real-time monitoring is adopted to replace daily manual timing and fixed-point inspection, so that troubleshooting negligence is avoided, and the working pressure of troubleshooting personnel is reduced.

Description

Technical field: [0001] The invention relates to an oil and gas wellhead valve and method for automatic inspection and intelligent remote control, belonging to the technical field of pipeline transportation. Background technique: [0002] With the continuous expansion of oil, natural gas and other liquefied gas mining scale, the currently used oil and natural gas and other liquefied gas mining and transportation devices are basically relatively traditional, requiring manpower to regularly search for potential leaks and on-site manual switch valves . [0003] First: The pressure of oil, natural gas and other liquefied gas mining and transportation devices in on-site operations is very high. Once leakage or other failures cause accidents, the consequences will be very serious, especially for on-site operators. . [0004] Second: With the continuous increase of resource demand, the number of oil production wellheads, gas production wellheads and other liquid and gas transmiss...

[0002] With the continuous expansion of oil, natural gas and other liquefied gas mining scale, the currently used oil and natural gas and other liquefied gas mining and transportation devices are basically relatively traditional, requiring manpower to regularly search for potential leaks and on-site manual switch valves

[0003] First: The pressure of oil, natural gas and other liquefied gas mining and transportation devices in on-site operations is very high. Once leakage or other failures cause accidents, the consequences will be very serious, especially for on-site operators.

[0004] Second: With the increasing demand for resources, the number of oil production wellheads, gas production wellheads, and other liquid and gas transmission pipelines is increasing, and the workload of manual well inspection is increasing, and the labor cost is getting higher and higher.
