NDQF-1 Series Electrically Oil System Fast Valve
1.Summarize
The NDQF-1 series electrically operated quick pass ball valve mainly uses in each industry oil quality, the gas or the steam pipeline. Its characteristic are: Thermo stable, the structure compact, opens shuts, the fluid to choke slightly rapidly, the leak-proof quality good, safe reliable. And the use maintenance is convenient, long life, has the accurate switch position feedback signal, and realizes the remote control and the automatic control ideal functional element as the industrial system, widespread application in domains, such as electric power, petrochemical, metallurgy.
2.Mail technology parameter
NDQF-1-15 NDQF-1-25 NDQF-1-32 NDQF-1-50 Nominal Size(mm) Φ15 Φ25 Φ32 Φ50 Nominal pressure(MPa) 6.4 Actuating medium temperature (℃) ≤350 Suitable Medium Oil, water, combustible air Open & shut time (s) ≤2 Control supply AC220V 50Hz Ambient humidity (℃) -30℃-60℃ Relative humidity ≤90%(25℃) other The environment does not contain the strong corrosive medium, not sharp shock.
3.Main structure and theory
Main structure: NDQF-1 series electrically operated quick pass ball valve mainly by electrically operated carries out the structure, the signal feedback system, to connect parts and so on frame, ball valve body to be composed. Carries out the structure including the top head, to decelerate the electric motor, the base plate, the micro-active switch/micro move switch/sensitive switch, the cam electrically operated and so on, has the structure to be compact, the position is accurate, contour artistic and so on characteristics. The diagram of mechanism sees Figure one; its relative position underwent the accurate adjustment before leaving the plant.
