OVERVIEW: ¡¡¡¡DPF-1
2000pulse electronic expansion valve is a kind
of speed-down style valve, which includes all
good peculiarities that motor-driven electronic
expansion valve has. It's pulse electricity
driver transfers power through speeddown gear
group and adjusts the rising process of valve
pin with bellows. The function of gear's slowing
down increases largely output torque so that the
small electromagnetic power could obtain the
plenty output moment. Its full open pulse is
2000. Its adjustment is more accurate and the
performance is better. The pulse electricity
driver and gear group can be easily split from
valves with different diameter orifice. It can
meet the needs of controlling flux in different
range, provided the valve is changed.
WORKING PRINCIPLE: ¡¡¡¡When the input
voltage pulse from controlling circuit are
applied to each coils in electricity driver, the
rotor in the driver is rotated by the magnetic
torque, making the valve pin rectilinear move
through the transmitting structure, and to
change the mass flow area of valve. In this way,
the mass flow can be adjusted automatically to
ensure that the system is kept in the best
state.
