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 generally utilized in most fields. And there exists one type of the particular valves, which is called as the crisis 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 gadget within 0.2-1 second. Thus, it is also called the fast 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 crisis action gadget under the disability of the electric actuator. Referring to the appropriate valve body, it differs because of the various and specified specifications and actual working conditions. Commonly, people can make an appropriate decision out of the ten major alternatives, such as the speedy action butterfly valve, fast action and full-function ultra-light valve and the speedy action single valve.
Once the signal of the requirement of the fast action van bướm điều khiển bằng điện 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 speedy action valve is broken, leading the switch from the exhaust state to the ventilation status. Thus, the adjustable stream rate of the air would endeavor to open or close the gadget 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 work on the speed of movement. Then, it is not wise to operate it too fast. Otherwise, it is easily to cause damage out of the fast 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 utilized 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 guaranteed.
