Emergency action working principle of pneumatic valve and matters needing attention

failure cases, in order to ensure the safety of system often need pneumatic valve in. Emergency ~ seconds on or off, have the function of regulating pneumatic valve pneumatic valve called quick action. Current of electric actuators are also unable to meet this requirement, can only adopt the way of pneumatic pneumatic valve and emergency action device, the pneumatic valve body part adopts form should be according to actual working condition into consideration, can choose in ten categories of regulating pneumatic valve, such as rapid movement butterfly pneumatic valve, quick action fully functional ultra light regulating pneumatic valve, quick action single-seat pneumatic valve, etc. A working principle,

in the pneumatic valve, after receiving emergency action signal moen da solenoid pneumatic valve change by air to exhaust, break fast dynamic pressure balance of the pneumatic valve, pneumatic valve by ventilation state switch for the quick action exhaust state, because the air is discharged into the atmosphere by the quick action of pneumatic valve ( Exhaust speed can be controlled by pneumatic valve current limiting, fastest. Within seconds, to slow the adjustable actuator compression spring fast restoration, the pneumatic valve opened or closed.
2, application note
( Pneumatic valve stroke shoulds not be too big, in order to improve the action speed.
( Movement speed shoulds not be too fast, too fast will impact breakage. Therefore, we should reduce speed, can be used. You don't have to. Seconds; In seconds. Seconds.
　　( Emergency cut-off pneumatic valve movement speed more shoulds not be too fast.
　　( Because of the low frequency, to improve the safety and reliability, should choose high reliability of electromagnetic pneumatic valve accessories, etc.
　　( Electric fast cutting pneumatic valve normally just walk completely trip ~ seconds ( °) 。
