CLOSING SPRING ASSEMBLY FOR PIVOTED-FLAP SLAMSHUT GATE |
摘要 |
<p>A slam-shut valve provides overpressure protection in a pipeline in the event of regulator failure. The slam-shut valve is normally held latched in the open position. Overpressure or failure of the regulator will automatically trigger operation of the slam-shut valve to close the same and prevent further passage of the gas through the pipeline. The slam-shut valve is manually reset to the open position once it has been triggered closed.</p> |
