Something Related to the Emergency Action Valve
The prosperity of the valve has been shown on all aspects of our daily life indeed. Actually, there are many specified types of the valve which are widely employed in mos elektrische uitlaatklep t fields. And there exists one type of the particular valves, which is called as the emergency action valve. According to the literary meaning, this kind of valve is expected to get the serious and emergent situation out.
It is important to take immediate action to ensure the security of the system under the unexpected failure moments. Generally speaking, the valve is required to open or close the device within 0.2-1 second. Thus, it is also called the quick action valve, belonging to the control valve. At present, the available way to achieve this function is just to combine the pneumatic valve with the emergency action device under the disability of the electric actuator. Referring to the proper valve body, it differs due to the various and specified specifications and actual working conditions. Commonly, people can make a proper decision out of the ten major alternatives, such as the quick action butterfly valve, quick action and full-function ultra-light valve and the quick action single valve.
Once the signal of the requirement of the quick action has been received, the solenoid valve would switch the ventilation status to the exhaust state. As a result, the balance of the pressure in the quick action valve is broken, leading the switch from the exhaust state to the ventilation status. Thus, the adjustable flow rate of the air would endeavor to open or close the device through the reset of the compressed spring.
As the effects taken by this kind of valve are increasingly greater, there are some points which need attention in order to make full use of it. Firstly, the travel of the valve should not be too long in order to improve the speed of movement. Then, it is not wise to operate it too quick. Otherwise, it is easily to cause damage out of the quick crash and is not able to meet the requirement timely. It is suggested to operate the valve according to its own specifications. What else, as the employed frequency of the valve is low, it is better to select the matching components with high reliability in order that the security and reliability of the whole system would be .
