Emergency action and working principle of the pneumatic valve note 4)

failure cases, in order to guarantee the security of the system, often in. Pneumatic valve opened or closed to seconds in emergency action as quick pneumatic valve pneumatic control valve, and other functions. Electric actuators are at present unable to meet this requirement, but the use of the choice of the top ten categories of pneumatic valves and pneumatic equipment, emergency action, part of the body, its form is the actual working conditions of should be considered, pneumatic control valve pneumatic valve, etc. , as a quick action to act quickly ultralight pneumatic valve fully open function, rapid action, single-seat pneumatic valve. First of all, the working principle of the received signal after emergency operation of pneumatic valves, solenoid pneumatic valve switch to the exhaust ventilation state in the country, breaking the fast dynamic pressure balance of the pneumatic valve, pneumatic valve quickly switch from exhaust ventilation state in the state, because of the fast moving into the atmosphere, through the pneumatic valve ( Exhaust pneumatic valve by limiting to control speed, the fastest. Second, in order to slow variables) In a rapid reset spring air compressors, pneumatic valve opened or closed. Second, application instructions ( ） Pneumatic valve stroke shoulds not be too big, in order to improve movement speed. （ ） Movement speed cannot too fast, too fast will impact damage. Speed should be as low as possible, therefore, cannot have. Second to. Second, there can be no second to. Seconds. （ ） Emergency shutdown pneumatic valve should not move too fast, and more. （ ） Motion frequency is low, in order to improve the safety and reliability, high reliability should be used solenoid pneumatic valve etc. （ 5) Power quickly cut off the pneumatic valve is commonly to seconds, and the whole trip, °) 。 This site keywords: pneumatic ball valve pneumatic ball valve pneumatic pneumatic valve pneumatic pneumatic valve pneumatic butterfly valve pneumatic butterfly valve pneumatic actuator pneumatic actuators
