There installs each diaphragm in both aligned working cavities(A)
&(B),which can be connected tonether with a central coupling
lever.The compression air enters the air distribution valve from
the air entrance of the pump,draw the compression air into one
cavity through the air distibution mechanism,push out the diaphragm
movement in the cavity.
The gas in another cavity will be drained.Once reaching the stroke
terminal,the air distribution mechanism will automatically draw the
compression air into another working cavity,push out the diaphragm
to move towards the opposite direction,so as to let the both
diaphragms continuously reciprocate motion in synchronism.
The compression air enters the air distribution valve from(E)shown
as the diagram,let the diaphragm piece move towards the right
direction.And the suction force in(A)chamber lets the medium flow
into from(C)entrance,push out the ball valve(2)to
enter(A)chamber,the ball valve(4)will be locked due to the suction
force;The medium in(B)chamber will be pressed,push out the ball
valve(3)to flow out from the exit(D).
Meanwhile,let the ball valve(1)close,prevent backflow.Such movement
in circles will let the medium uninterruptedly suck from(C)entrance
and drain feom(D)exit.
