Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipelines, in particular to a natural gas safety valve opening state detection device. Background Art

[0002] In the natural gas supply system, the safety valve is one of the key components to ensure the safe operation of the system. Its main function is to automatically open to release excess pressure when the internal pressure of the system exceeds the set value, thereby preventing the system from malfunctioning or exploding due to overpressure. However, with the long-term operation of the natural gas supply system, the safety valve will also experience continuous wear and aging. These changes may cause the opening and closing performance of the safety valve to deteriorate, or even cause abnormal opening and closing.

[0003] This abnormal opening and closing state is often difficult to be discovered by staff in time, because traditional safety valves are not equipped with an effective state detection mechanism. Therefore, when the safety valve is in an abnormal state, once a natural gas leak occurs, it will pose a great threat to people's lives and property safety. The existing safety valve state detection methods usually rely on manual inspections or regular maintenance. The disadvantage of this method is that it is not only inefficient, but also difficult to ensure the accuracy and reliability of the detection results. At the same time, due to the subjectivity and uncertainty of manual inspections, it is difficult to detect and deal with the abnormal opening and closing of the safety valve in time.

[0004] In order to solve the above problems, without affecting the normal use of the natural gas safety valve, the opening and closing status of the natural gas safety valve can be detected, so that the staff can promptly discover and deal with the abnormal opening and closing problems of the safety valve, thereby ensuring the safe operation of the natural gas supply system. For this purpose, we propose a natural gas safety valve opening status detection device. Utility Model Content

[0036] Instructions

[0037] When the pressure inside the natural gas pipeline 1 is too high and the safety valve 4 is opened, part of the natural gas will be discharged along with the opening of the safety valve 4, and then spread inside the pressure relief pipe 2, and discharged through the valve hole 3 on the side of the pressure relief pipe 2.
