The flow to the high pressure water chamber 4 is discharged through the water outlet 53 of the upper cover 50. The flow of water from the water inlets 65 of each zone will continuously enter the drains of the zones on the drain seat 61 in the wheel, and the blades on the pad 70. Also, as the upper jaw opens the dream alternately, and the effect of opening or closing the zones is indeed achieved, the loss of the water leakage pressure can be achieved, and the service life of the reverse diaphragm pad 70. The above-mentioned piston valve body 60 and the anti-reverse rubber pad 7 〇^ After the actual mold opening test, although the effect of “reducing the amount of water added and discharged” was achieved, the inventor Therefore, under the same horsepower output condition, it still has a full-scale pressure without any loss of pressure, and it is considered that after 5 membrane booster pump 1, the arrow in the twelve water taps enters the reciprocating shaft of the lower 13 Tap water W, 升压 升压 升压 升压 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 70 "Focus pressure" and "increased by 1 to satisfy, the total has not reached the improvement space of 10 201007015 overall supercharging efficiency. [Inventive content] The main object of the present invention is to provide a "diaphragm type supercharger · f The piston valve ϋ structure is improved. The raft is attached to the drain seat of the piston valve body. The top surface is set with the boring position: the hole core is the lowest point: it has a concave arc surface, and the water inlets are The contact surface of each piston piece is also the lowest point of the center of the positioning hole, and is also provided with a concave curved surface in the direction of Φ. When the positioning post of the anti-reverse pad is embedded in the positioning hole of the drainage seat, , the bottom surface of the anti-reverse pad and the concave curved surface of the top surface of the drainage seat A gap is formed therebetween, and the positioning posts of the piston pieces are respectively embedded in the positioning holes of the water inlet seat, and a gap is formed between the bottom surface of each piston piece and the concave arc surface of the water inlet hole. By the action of each of the gaps described above, the anti-reverse pad and the piston piece can generate a stronger Φ adsorption force under the action of the piston push block, thereby further improving the overall supercharging efficiency. Another object of the invention is to provide an "improvement of the structure of a piston valve body of a diaphragm type booster pump", in which the anti-reverse pad and each piston piece are designed to have a thick central portion but a thin edge, so that The force strength will be more durable than the conventional flat structure with the same thickness from the center to the edge, and each blade and each piston piece on the anti-reverse pad can be activated under each interactive opening and closing operation. It is more effective to achieve the effect of closely closing the drainage hole and the water inlet hole 201007015. Therefore, the present invention can completely eliminate the "pressure loss" problem of the piston valve body in the conventional diaphragm type booster pump. Another object of the present invention is to provide an "improvement of the structure of a piston valve body of a diaphragm type supercharged chest", because the anti-reverse rubber pad in the piston valve body is a single component integrally formed, so it will be more in the process of assembly.

[Embodiment] Referring to the thirteenth to sixteenth drawings, the "the structure of the piston valve body of the diaphragm type booster pump is improved" is the top surface of the center drain seat 101 of the piston valve body 1 A concave curved surface 107 (shown in FIG. 14 and FIG. 15) with an inwardly facing concave arc surface 107 as the lowest point of the center of the positioning hole 102, and a piston piece 300 corresponding to each of the water inlet seats 104 is attached The contact surface is also provided with an inward concave concave surface 1〇8 (as shown in FIG. 15) with the center of the positioning hole 1〇5 as the lowest point, and the plug is placed in the center of the piston valve body 100. The anti-reverse pad 200 and the positioning post 2G1 in the drain seat ι〇ι are made of the same soft elastic material and integrally formed into a single-element (as shown in FIG. 14-a); The top surface of the crucible is provided with a convex circle (four), and the bottom surface 2〇3 is provided with a plane such that the thickness u between the central position of the top surface 202 and the bottom surface 2〇3 is higher than that of 201007015 The thickness η between the outer peripheral top surface 202 and the bottom surface 203 is large (as shown in the fifteenth figure), X the top stomach of each piston piece 3〇〇 It is provided with a convex arc surface, and its bottom surface 3〇3 is disposed in a plane such that the thickness between the central position of the top surface 302 and the bottom surface 3〇3 is also larger than the outer peripheral top surface 3〇2 and the bottom surface. The thickness t4 between 3 and 3 is large (as shown in Fig. 14b and Fig. 15). Continuing with the sixteenth to eighteenth illustrations, when the positioning post 2〇1 of the anti-reverse pad 2〇〇 is embedded in the positioning hole 1〇2 of the drain seat 1〇1, the anti-reverse capsule A bottom surface 2〇3 of 200 and a concave curved surface 1〇7# of the top surface of the drain seat 1〇1 may be formed with a $胄(1) (as shown in the sixteenth figure), and the respective piston pieces 3〇〇 After the positioning posts 3〇1 are respectively embedded in the positioning holes 1〇5 of the water inlets 1〇4, the bottom surface 303 of the piston piece 3〇〇 and the concave arc surface 1〇8 of the water inlet hole 1〇6 are both A gap G2 is also formed (as shown in Fig. 16); by the action of the gap G1 and the gap G2, the thrust pad 2〇〇 and the piston piece 3 can be smashed by the piston push block 23 Under the action, f produces a stronger adsorption force', and then the diaphragm press type increases the amount of money in the middle and low M water chamber 3, the second pressurization action and the second pressurization operation in the high pressure water chamber 4 after the overall pressurization The efficiency will have a greater improvement, so the purpose of improving the supercharging efficiency can be achieved. At the same time, because the anti-reverse pad 200 and each of the piston plates 300 are structurally thick at the center but thin at the edges, the strength of the 201007015 is therefore strong. meeting It is conventional that the center-to-edge is a flat structure of the same thickness with better durability, and each of the blades on the anti-reverse pad 2 and each piston can be activated by each interaction opening and closing operation. The sheet 300 can more reliably achieve the effect of closely closing on the drainage hole 〇3 and the water inlet hole 106 (as shown in the seventeenth and eighteenth drawings), because the present invention can use the conventional diaphragm The "pressure loss" problem of the piston valve body 30 in the booster pump ι is completely eliminated; further, since the anti-reverse rubber pad 200 is a single-component formed in the present invention, it will be more in the assembly process. The conventional diaphragm type booster pump is faster and more time-saving, which can greatly reduce the labor cost of production. For the diaphragm-type booster pump products that are mass-produced, the commercial competitiveness of economical mass production benefits is higher. According to another embodiment of the present invention, in another embodiment of the present invention, the bottom surface of the anti-reverse pad 2 更 is further provided with an inward concave concave surface 204 ′ and The bottom surface of the piston piece 300 is also provided with an inward concave curved surface 304 (such as the nineteenth figure). The gap G3 formed between the concave curved surface 204 of the check rubber 200 and the concave curved surface 107 of the top surface of the drain seat 1〇1 is larger, and the concave curved surface 304 of the piston piece 300 is shown. The gap G4 formed between the concave arc surface ι 8 of the water inlet hole 106 is also larger (as shown in the twentieth diagram), so that the anti-reverse capsule 200 and the piston piece 3 are subjected to the piston. Under the action of push block 201007015 23, the generated adsorption force is more powerful, and the overall boosting efficiency will also achieve a greater improvement effect.
