By using the part 13a of the valve to block the vent hole to achieve the minimum area necessary to maintain the valve action, the valve can be easily opened and closed. That is, the valve can be opened and closed even by simply increasing or decreasing the pressure in the pump chamber, so it can be used even in a smaller diaphragm pump. 23A-I, FIG. 23A-II, FIG. 23B-I, and FIG. 23B-II, similarly, a part of the shape of the valve is made as shown in FIGS. 23D-I and 23D-II. Like 13a, it can be used in smaller pumps. The discharge valve used in the diaphragm pump of the present invention is shown in Figs. 23A-I, 23A-II, 23B-I, 23B-II, 23C-I, 23C-II, 23D-I, and 23D-II As shown in FIGS. 23E-I and 23E-II, each has a flange 13c. However, the discharge valve does not necessarily have to be provided with the flange 1 3 c. In this case, a valve pressing portion is provided in the gas collecting member, and the discharge valve can be pressed and fixed by using a portion other than the valve portion 13a functioning as a valve.

Description of the invention (9) The discharge valve is formed by fitting the concave portion 1 3 i with the ^ formed on the valve cover with a convex portion After the configuration is completed together, the valve is pressed and held by the 'door mounting portion of the air collector. Furthermore, by using the air-collecting member = the door pressing portion ', a portion other than the vent hole (a position corresponding to the intermediate door pressing edge 1 3 c in FIG. 2) is pressed to make the protrusion in the bottom temple of the valve at this portion. Tightly combined and used. -The front and middle door covers are tight. The concave surface of the discharge valve shown in Figure 2 3 F-I and Figure 2 3 F-I I. However, 疋 does not limit the concave surface to a spherical surface. For example, other shapes such as a curved surface or a conical surface may be used. In other words, the $ approximate sphere may be a curve or a triangle shape other than the arc. The surface shape is the one. When the valve is pressed by the valve pressing part, the valve cover is. At least, the valve is tightly connected with the vent hole, and the vent hole is at least radiated.... Σ is placed on the door, and each vent hole is cut off from other vent holes. In addition, when the valve is compressed in the early manner, if the entire periphery of the valve is integrated with the valve cover 9 for 13 hours, the concave shape of the valve and the valve compression / blanket can be used. The shape of ′, ° 丨 is the valve shown in FIGS. 23G-I and 23G-II, and the convex portion l3j is provided at the center portion of the concave surface g of the valve 13 as in FIG. 23B! The discharge valve in the picture is different. 1 That is, the valves of FIGS. 23G-I and 23G-II are arranged in the valve cover so that the convex portion 13 is fitted into the concave portion provided at the corresponding position on the valve cover. 1 Here, by using the valve pressing portion to press the valve 3 into the valve cover, the concave surface 13g of the door 13 is tightly bonded to the surface of the valve cover.

Therefore, it is possible to completely close the valve in the same manner as the valves of Figs. 23F-1 and 23F-II. ’Even at low pressure

Each of the doors in Figure 23H-I is shown in Figure 23HM 1. The valve shown in Figure 23HM1 has a knot with a flange 13k between the parts to play the role of the valve. = Cover cow

Screen Γ: Second, the door reader shown in Figs. 23H-n has a structure using a wide door n and a flange 13k, so the opposite side of the flange 13k is often clever ::, knife blade, etc. on the valve cover. And 'Even if the flow from the vent hole ΔΜ_ Asian deforms the valve part and opens the peripheral part 1 j 31 of the valve part, it can always ensure a tight gas seal. Therefore, between the Tongtai hole and the vent hole The space is often tightly attached, and each vent hole is separated in the state of being sealed. Figures 23H-I and 23H-II show the valve 13. Because the phase side of the flange 13k is usually closely attached to Valve covers, etc., so it is best not to place the vent hole in or near it. Therefore, for the valve, the position determination is necessary.

The valve I shown in FIGS. 23H-I and 23H-II is an example of a discharge valve having a three-valve part for a diaphragm pump having three diaphragm parts (chest chamber). 1 3e Make a triangle (equilateral triangle) to determine the position. Further, a triangular convex portion is provided on the valve cover, and the triangular concave portion i3e of the partition door 13 is moved together with this convex portion to determine the position. The valves shown in Figs. 23I-I and 231-2 are similar to the valves shown in Figs. 23H-I and 23H-II, and have a flange 13k shape. However, the valve's

Description of the invention (11) It is characterized in that its concave surface 13 is also provided with a flange 13m ° Although the flange 13m of the valve is in the same position as the flange 13k, the height of the flange is relatively small. When the flange 13m is provided on the inner concave surface 'when the valve is pressed by the valve pressing portion, the inner side at least the flange 13m and the surface of the valve cover are tightly coupled together. In addition, by pressing the flange 13k, the concave surface 13g does not come into contact with the surface of the valve cover, and the peripheral portion 13h of the valve 13 is brought into close contact, so that the valve 13 operates at a low pressure. In this way, for the valve in Fig. 231, "丨 ~ II, in the squeezing of the * | port, j i j 5 ′ -lx m” passes; one of the peripheral parts 13h needs to have a close-fitting structure. For this reason, the surface (thickness) of the flange 13 m is best, and the peripheral part of the valve when the valve is squeezed should not be too large. In addition, for the structure, as shown in Figs. 23 I to 23 and Figs. 23 I to I I, the length is closer to the inner side than the junction edge 13h which is in close contact with the diaphragm portion. It is separated by the flange 1 3ιn Nu Jia Weigu and the vent hole by the flange 13m. When the wide door is squeezed, the passage / circle 13h as a whole is closely attached to the valve cover. When the pressure of the peripheral air holes of the flange 1 3m does not increase, the valve is closed. Therefore, the pressure from the pump chamber becomes larger, and the pressure of the pump chamber is opened to the body side for 13 hours by the pressure of the pump chamber, and the pressure of the fluid flowing to the vent hole that discharges D ... is attached to the valve cover. On the 9th, it communicates with other d: Because of the flange c, it will not affect other pump rooms. They are tightly spaced apart from each other as described above, although the valves shown in Figure 23G-I, Figure 2 ° Saki'-II, Figure 23I-I, Figure 23I-II, G, n, and Figure 23H] The concave portion 13g has a spherical shape, as shown in FIG.
