Working principle of the present invention is following:
The inlet hole air inlet of source of the gas from the valve core housing, gas enters into the center annular chamber, and then, the air hole of gas from the spool of center enters into air-inlet cavity.Because this moment, poppet shaft can not be in the state of equilibrium of forces fully, so gas can promote poppet shaft to a side shifting.
Suppose that gas promotes poppet shaft earlier and moves to the left, at this moment, the central channel on the poppet shaft can constantly be shifted to air distribution cavity position, left side and constantly communicate with it, so gas can be from the air distribution cavity that constantly fills into the left side along the slit between central channel and the left side air distribution cavity.Along with the air pressure in the air distribution cavity of left side constantly increases, the center spool can constantly move to right along poppet shaft under the effect of air pressure.Then, the right side air distribution cavity constantly is communicated with the sidepiece annular chamber on right side.
The center spool moves to right in the process; Air outlet hole on the left end spool opens wide gradually and is communicated between left side sidepiece annular chamber and the left side outlet chamber; And this moment; Because poppet shaft moves to the left, so the gas in the sidepiece annular chamber of left side gets into the left side outlet chamber through air hole, finally outside air outlet hole is discharged the pump housing of membrane pump with pneumatic drive; Meanwhile, the right side air vent constantly opens wide and is communicated with air-inlet cavity, and the part gas in the air-inlet cavity can constantly transfer to the cavity between right side diaphragm and the intermediate from air vent.
Spool moves to low order end when the center, and the left side air distribution cavity is full of by gas, and this moment, gas became one the tunnel, only along the air vent cavity between diaphragm and the intermediate to the right.Along with the air pressure of this cavity increases gradually, air pressure promotes the right side diaphragm and moves to the right, and the right side diaphragm drives central shaft and moves to right simultaneously, and central shaft drives the left side diaphragm and moves to right, and the left side diaphragm promotes poppet shaft and moves to right.
Along with constantly moving to right of poppet shaft, the central channel on the poppet shaft can constantly be shifted to air distribution cavity position, right side and communicate with it gradually, so gas constantly fills in the air distribution cavity on right side along the slit between central channel and the right side air distribution cavity again.Simultaneously, sidepiece annular chamber in left side is communicated with the left side air distribution cavity.
Along with the air pressure in the air distribution cavity of right side constantly increases, the center spool moves to left, and the left side air vent constantly opens wide and is communicated with air-inlet cavity, and at this moment, the part gas in the air-inlet cavity can constantly transfer to the cavity between left side diaphragm and the intermediate from air vent.With its simultaneously, the gas in the air distribution cavity of left side enters into the left side outlet chamber and enters into outlet chamber from the air outlet hole in left side again and finally discharge from exhaust port.
So to-and-fro motion has realized the purpose of the left and right swing of central shaft.
When the right side diaphragm moved to right, the liquid in the liquid container of right side was extruded, and sucked liquid in the liquid container of left side simultaneously.When the left side diaphragm moved to left, the liquid in the liquid container of left side was extruded, and simultaneously, sucked liquid in the liquid container of right side.So, working in reciprocating mode, the purpose of liquid is got in realization.
