Emergency explosion-proof power-off reset electric gate valve overview and function

First, the product overview:

 

The explosion-proof power-off reset actuator has the active defense function in the emergency situation, which is the power-off self-reset function and the temperature sensing function. It can realize the opening and closing of the self-run control valve in the case of sudden emergency, which satisfies Protection requirements for opening or closing of a valve in an emergency.

Second, two special features:

 

1, power off reset function

 

In normal use, if an emergency occurs, the external power supply must be cut off! When the emergency occurs in dangerous goods storage tanks, oil pipelines, etc., the valve is closed!

 

The explosion-proof power-off reset actuator automatically runs the shut-off valve when the external power is disconnected (power off, power off). The factory setting is optional.

 

2, ambient temperature sensing function

 

In the event of a fire, when the power supply is too late, the explosion-proof electric reset actuator detects that the ambient temperature around the storage tank or pipe exceeds the safe value for 10 seconds (the excess value can be set, the factory default temperature is 90 degrees, the time is 10 seconds). Immediately perform the valve closing action to achieve the active defense function (select different temperature levels according to the site conditions, fully meet the site temperature standards for valve opening and pipe).
