Each of the grooves 272a and 272b defines a communication tube 273a, and the connecting pipes 273a and 273b respectively and the two side covers 27a. The first and second air outlets 274a and 274b that are laterally opened in 27b are connected to each other. In this way, the compressed air entering from the main intake 7 M418202 hole 211 enters the air guide branch 212, and is connected to the annular grooves 272a, 27 of the two side covers 27a' 27b at both ends of each air guide branch 212. After the tubes 273a and 273b are 'received' by the first and second air outlets 27, the discharge is measured. The first and second air outlets 274a and 274b are interposed between the first and second air intake holes 181a and 18a, and the first and second air outlets f 275a and 275b are connected to each other so that the air source is continuously The second air outlet holes 273a and 273b are discharged, and pass through the first and second air outlet pipes 275a and 275b to enter the first and second air intake holes 181a and 18b. The outer surfaces of the flanges 271a, 271b of the two side covers 27a, 27b are sleeved one by one, the airtight ring 23, and the first and second air holes 274a, 274b of the flanges 271a, 271b are axially opened. The valve rod 26 is sleeved, and a second positioning groove 276a, 276b is disposed on the inner wall, and an inner airtight ring is disposed in each of the second positioning grooves 276a and (10), and then the sleeve is further adjusted by the pair of wear materials. For example, a wear ring made of Teflon is used to increase the wear resistance of the valve stem 26. Referring to Figures 3a and 3b, the air source enters the valve body 21 of the pneumatic control valve 20 from the main air inlet 211. At this time, the valve stem 26 is located at the first position on the left side of the fixed sleeve 22 and the side cover 27b. The retaining ring 261 is located below the second spacing rib 221, and the third and fourth air holes 222c, 222d are opened by the two air guiding grooves 263, and the compressed air is the third and fourth air holes 222C, 222d and the second leading The air vent 215 enters the first air guide 218 and passes through the second main passage hole 182b in the direction of the arrow c to enter the second air chamber 12a of the second pump chamber 12. At this time, the diaphragm piece 17b on the right side is pressed to the left to form a pressure feed stroke, so that the liquid in the first liquid chamber 12b is pressed and passed through the check valve 142b' which is opened by the liquid outlet passage 4 The nozzle 141 flows out. Since the two diaphragm pieces i7a, 17b are connected by a main shaft 16, when the diaphragm piece 17b of one side (right side) is pushed out to the left and the liquid is pumped, the diaphragm piece 17a of the other side (left side) is displaced by the spindle 16 displacement. The first liquid chamber 11b is filled by contracting to the left and performing the opposite liquid suction stroke so that the first body chamber 11b is sucked into the liquid ' from the water inlet 151 of the liquid inlet passage 15 and passes through the check valve 152a which is opened. liquid. 8 M418202, while the aforementioned pressure feeding and liquid suction strokes, the air guiding branch pipe 212 communicating with the main air inlet 211 passes part of the compressed air through the communicating tubes 273a, 273b of the side covers 27a, 27b, and is first, The second air outlets 274a, 274b enter the first and second air outlet pipes 275a, 275b, respectively, and then enter the first and second air inlet holes 181a, 181b in the directions of arrows A, B, respectively; The second switching valves 183a and 183b are closed, so that the first and second air outlet holes 274a and 274b are in an equal pressure state with the first and second air intake holes 181a and 181b. When the left diaphragm piece 17a is displaced to the left by the main shaft 16, and the first switching valve 183a is touched and opened, 'the compressed air in the first intake hole 181a is passed along the arrow a side toward the first switching valve 183a, and The air in the first air chamber 11a is pushed by the left diaphragm piece 17a, and is discharged by the first main vent hole 182a, and passes through the first air guiding tube 217, the first main air hole 213, the second, in the direction of the arrow D. The first air hole 222b: 222a is discharged by the first exhaust hole 214 in the direction of the arrow e. In this way, y causes an instantaneous pressure drop between the first air outlet 274a and the first air inlet hole 181a, so that the air pressure is smaller than the air pressure between the second air outlet hole 274b and the second air inlet hole, and the valve stem 26 is shifted to the right. The second position is shown in Figure 4b. Referring to FIG. 4a and FIG. 4b, the valve stem 26 has been displaced to the second position of the fixed sleeve 22 and the right side of the first side cover 27, and the retaining ring 261 is moved to the third spacing rib 221, and the second The third air holes 222b and 222c are opened, so that the compressed air passes through the third air holes 222c, the first air guiding groove 262, the second air hole 222b, and the first main air hole 213 into the first air guiding pipe 217' and passes through the arrow d direction. The first main passage hole 182a enters the first air chamber 11a of the first pump chamber. At this time, the left diaphragm piece 17a is pressed to the right to form a pressure feed stroke, so that the liquid in the first liquid chamber i1b is pressurized, and is opened 142a through the liquid outlet passage 14, and then flows out from the water outlet 141. While the diaphragm on the other side (right side) is still contracting rightward, the opposite liquid suction stroke is performed, so that the second liquid chamber must suck the liquid from the water inlet 151 of the liquid passage 15, and pass through the check valve 152b which is opened. The second liquid chamber 12b is filled with liquid. 9 M418202 When the right diaphragm piece 17b is moved to the right by the spindle 彳6, and the second switching valve 183b is touched and opened, the compressed air in the second intake hole 181b is passed through the second switching valve 183b in the direction of the arrow B, and And the second air chamber 12a (10) air is pushed by the right partition 17b' * is discharged by the second main vent 182b, and passes through the second air duct 218, the second main air hole 215, the fourth, fifth air hole 222 along the arrow c. (j, 222e, (4) The second exhaust hole 216 is discharged in the direction of the arrow F. This can be: an instantaneous pressure drop occurs between the f hole 274b and the second intake hole lion, so that the air pressure J, the = air outlet 274a The air pressure between the first air intake hole 181a and the rightward position to the first position as shown in FIG. 3b; therefore, the dry door motion control valve 2 〇 repeats the above action, so that the chest chambers on both sides ^, 12 , = current delivery, pressure delivery and aspiration movement, to complete the work of liquid delivery in the county. Therefore: through the implementation of this case, the effect of the gain is that the external valve is recorded and separated, and between the two Connect the air tube with two domain tubes. If the diaphragm in the millet ruptures, there is liquid remaining: the liquid does not flow. In the external pneumatic control valve, the inner casing of the special control valve and the locating groove in the hood can be increased, and the wear-resisting effect can increase the pneumatic control, which is a great structure that has never been seen before. The person disclosed in the case of the present invention is a kind of decoration of the preferred embodiment and is derived from the technical idea of the case, and is more suitable for those who are familiar with the skill. _ The person who is easy to infer, Figure 1 is a simplified view of the separation of the case _ Qiangian County Puzhi. Figure 2 is an exploded perspective view of the external pneumatic control side of the case. Figure 3a and Figure 3b show the separation of the pneumatic double rod in the first position Sectional view. / When tilting, the spindle and valve diagram 乜 and Figure 4b are the cross-sectional view of the split pneumatic rod in the second position.
