Air pressure when sending natural gas in appendix is maintained at an equilibrium valve with buoy and the air pressure in movable plate, when going out in appendix
Existing gas leak phenomenon, the air pressure in appendix reduces, therefore the air pressure among mounting base internal float and movable plate is more than appendix
In air pressure so that buoy down moves, movable plate up moves, therefore can pull or break sensing line, and senses
When line is pulled or breaks so that alarm is powered, and alarm sounds the alarm after being powered, and work people is reminded so as to reach
Member, while controlling switch closes so that electrically operated valve closes appendix, so that prevent natural gas from leaking outside, the apparatus structure
Simply, it is powerful, appendix that section can be detected there are gas leakage, and can be sounded the alarm by alarm, so as to notify work
Make personnel and rush to repair pipeline as early as possible, while appendix can be automatically closed by motor-driven valve, so as to prevent combustion gas from leaking outside, therefore avoid
The wasting of resources and environmental pollution.
