Description

Technical Field

[0001] The utility model relates to the technical field of pipeline gas valves, and more specifically to a pipeline gas self-closing valve. Background Art

[0002] The pipeline gas self-closing valve is generally installed upstream of the indoor stove to cut off the gas when the pressure and flow of the gas system are abnormal. The gas supply will be restored manually after the cause of the fault is found and eliminated. The self-closing valve has three protection modes: overcurrent, overpressure and underpressure. Its overcurrent automatic closing can effectively solve the rapid gas leakage accidents caused by the detachment and rupture of the indoor rubber hose. The overpressure automatic closing of the self-closing valve can prevent the damage of gas equipment or gas leakage accidents caused by the sudden increase of indoor pipeline pressure. The underpressure automatic closing of the self-closing valve can prevent the emptying of the user's branch pipe caused by the reduction of gas pressure or gas outage maintenance.

[0003] The pipeline gas self-closing valve itself can automatically close without electricity or other external power when the gas pipeline supply pressure is overcurrent, underpressure, or overpressure, and must be manually restored to reopen. The actual working state of the pipeline gas self-closing valve can only be known through manual inspection. Therefore, the special working mode of the pipeline gas self-closing valve makes it very difficult to digitize the status information of the pipeline gas overcurrent, underpressure, and overpressure and upload it to the cloud to realize remote perception of the working state of the pipeline gas self-closing valve. Therefore, it is impossible for the gas company to grasp the gas operation status in real time and notify users in time that the pipeline gas abnormality requires inspection and maintenance, which seriously hinders the improvement of gas safety and service quality.
