The concave ring groove (313) (314) is internally nested with a sealing ring (315) (316); the piston rod (32) is made of a metal material, and the two wide diameter flat ends (321) (322) are just Closely inserted in the seal ring (315) (316) of the cylinder chamber A (311) and the cylinder chamber B (312), so that the piston rod (32) does not accumulate carbon scale under long-term reciprocating operation, and is effective. Play more practical and durable life. U The above is the structural improvement of the creation of the pneumatic double diaphragm fruit (1), and its components are related to the structure and location. 7 M336999 Secondly, the principle of the structure improvement (1) of the pneumatic double diaphragm pump of the present invention is explained as follows: As shown in the third to sixth and eighth figures, the air from the pump body (20) When the inlet port (211) is filled with high-pressure air, it will sequentially fill the runner (212), the guide runner (213), the lower right runner (214), the right chamber (215), and the lower left runner ( 216), left chamber (217) in each air source flow channel; action 1. The south air of the guide channel (213) will be controlled upwards via a reversing valve (3〇), and then from the left channel (221 And the left air outlet (222) pushes the left diaphragm (2Ό, which is moved by the main shaft (28) to pull the other end diaphragm (29) to contract inward, resulting in the right diaphragm (29) The valve needle (262) of the washer (291) touch control valve (26) moves inwardly to open the passage (2623); when the right diaphragm (29) contracts inward as described above, the high pressure air passes through the right air outlet. (242), the right drain (241) enters the reversing valve (30), and is vented downwards to discharge from the exhaust vent (233) to the outside; ® as for the right chamber (215) The open path (2623) enters the control valve (26), and then turns from the radial through hole A (2613) of the seat body (261) to the upper right turn flow path (231) into the reversing valve (30) to convert the high voltage. The air direction; and the high-pressure air in the upper left runner (251) is discharged from the left exhaust port (252); action 2: as shown in the third to sixth and ninth, The high pressure air of the deflector (213) is controlled upward via the reversing valve (30), and the right diaphragm (29) is pushed outward from the right drain (241) and the right air outlet (242) by the main shaft. (28) Move the other 8 M336999 end left diaphragm (27) to contract inward, causing the valve (262) of the left diaphragm (27) to press the valve needle (262) of the pressure control valve (26) to contract inward. Open the passage (2623); - When the left diaphragm (27) contracts inward as described above, the high-pressure air passes through the left air outlet (222) and the left intake passage (221) into the reversing valve (3〇)辗 Turning down from the exhaust vent (233) to release the air to the outside; as for the left chamber (217), the air source is from the open passage (2623) into the control valve (26), and then from the seat (261) The radial through hole a (2613) turns upward from the #upper turn channel (251) into the reversing valve (30) to switch the direction of the high pressure air; and the high pressure air in the upper right turn channel (231) The pressure is discharged from the right exhaust port (232); according to the above-mentioned action 1 and action 2, the left diaphragm piece (27) and the right diaphragm piece (29) are alternately pushed and pulled in an instant, and the liquid is sucked, The mouth p is pressed out. In summary, it can be understood that the creation of the "Pneumatic Double Diaphragm Pump Structure Improvement (1)" is a creative new creation, and in the same technical field, there is no product or similar product. The creation or public use of the product has (1) tightly assembled and controlled paste in the right and left chambers of the county body, and the practical efficiency of stabilizing the quality; (2) the flat end of the piston rod of the reversing valve is designed to make the piston Under the long-term reciprocating action, the rod will not accumulate carbon scale, and the effect of using the higher practical value and the durability of the life will be enhanced, and the value of the industrial use will be improved. On the whole, it is an excellent design and the dog should be designed. The various requirements of the new patent law, 提出 patent application. 9 M336999 [Simple description of the diagram] The first picture is a combination of the conventional plan view.
