Block diagram of control QK-
-A/B
BLOCK DIAGRAM OF TYPE QK
-C
Positioner of pneumatic valve functions subject to the principle of balance between torques. When
the signal pressure entered corrugated pipe (1) is increased enough, it causes the major lever (2) to
turn round the fulcrum (15) and so retainer (13) aproaches the spray nozzle (14) to produce a back
pressure. After amplified by two-way amplifier (16) the back pressure is put into gas chamber of
piston mechanism (8) and causes the piston to produce a displacement to push the pork connected
rigidly to push rod of operating mechanism to turn a rotation of 90º and to drive the feedback cam
(5) to rotate counterclockwise as to draw the feedback spring(11). When the force of feedback
spring is equivalent by torgue to the force of signal pressure acting on corrugated pipe, the lever
system reaches balance. Then certain signal pressure is corresponding to certain angular motion of
valve. Spring (12) is used for zero Regulation

BLOCK DIAGRAM OF TYPE QK
-D/E
When the current signal from the electric regulator
enters the coil of torque motor assembly(1),a magnetic
field is formed in the gap of torque motor. Acting
together with the permanent magnetic field, the gap
magnetic field causes the armature(2) to produce a
force towards left and make the major lever amature
(2) turn round the fulcrum (15) so that the retainer (13)
approaches the spray nozzle (14) to produce a back
pressure. Amplified by the amplifier (16), the back
pressure is put into gas chamber of piston mechanism
and causes the piston to produce a displacement to
push the pork connected rigidly to push rod of operating
mechanism to turn a rotation of 90º and to drive the
feedback cam (5) to rotate counter-clockwise as to draw
the feedback spring(11).When the feedback spring is
equivalent by torque to the force of torque motor acting
on major lever, the lever system reaches balance. Then
certain signal current is corresponding to certain
position of valve. Spring (12) is used for zero regulation
SPECIAL APPLICATION
1.Two-style pneumatic cut-off control: This is a special product of
pneumatic actuator and can carry out two-phase opening or two-phase
closing, i.e. one-phase opening and two-phase closing, two-phase
opening and two-phase closing, Two-phase opening and one-phase
closing according to flow performance. It is mainly used for ball valve
and can prevent the valve from leakage and failing of opening and
closing. It can slow the speed during opening and one-phase closing
and can make the fluid vary smoothly to avoid the explosion caused by
water hammer in inflammable liquid. It can also prevent measuring
instrument in system from damage caused by shock. So it suitable for
petrochemical works and biological product manufacturers
2. COMBINATION OF TYPE QKX CONTROL BOX AND TYPE QKPNEUMATIC VALVE ACTUATOR
-A
As the control box is a out door sealed device designed specially for
the users, the combination can be used to control the opening and
closing of valves, such as pneumatic butterfly valve, pneumatic ball
valve etc. used in adverse circumstances and service condition to carry
out local operation, remote and centralized control
