The diaphragm pump assembly (A) according to the present invention further relates to a pump for sucking and discharging a fluid by flowing the packing member (20)

A diaphragm 30 is provided between the upper body 11 and the lower body 13 for the flow of the packing member 20.

The diaphragm 30 is formed in the shape of a triangle having the same shape as that of the housing 10 and has a structure divided into three zones so as to correspond to the zones of the upper body 11, respectively.

At this time, protruding protrusions 31 are formed between the respective zones so that the zones are not invaded, and each zone has the same structure, and one zone will be described as an embodiment.

First, an air hole 33 is formed in each region of the diaphragm 30, and a seating portion 35 is formed on the air hole 33.

A moving part 37 is formed around the air hole 33. The moving part 37 is made of a soft material and can move up and down to move up and down according to the operation of the pump.

Each of the sections of the diaphragm 30 is configured to correspond to each section of the upper body 11 so that the seating section 35 and the moving section 37 are connected to one of the upper bodies 11 And the suction part 115 and the discharge part 117 provided in the area of the discharge space.

The diaphragm pump assembly A according to the present invention is provided with a triangular frame 30 for raising and lowering the diaphragm 30 and more specifically for lifting and lowering the moving part 37 provided on the diaphragm 30, (40).

More specifically, the triangular frame 40 is inserted into the insertion portion 131 of the lower main body 13 and has a circular body portion 41 and a triangular shape formed on the body portion 41 And a push portion 43 composed of three pieces.

The push portion 43 is inserted into the insertion hole 131A of the lower main body 13 so as to be closely attached to the moving portions 37 of the respective regions of the diaphragm 30.

At this time, the push portion 43 is formed with a pressing surface 431 capable of pushing the moving portion 37 of the diaphragm 30, and an insertion portion 433 is formed at the center of the pressing surface 431 .

The pressing surface 431 of the push portion 43 penetrates through the insertion hole 131A of the lower main body 13 and is inserted into the diaphragm 30 when the triangular frame 40 is moved up and down by the driving means. When the triangular frame 40 is lowered, the fluid portion 37 of the diaphragm 30 can be lowered naturally by the pressure of the fluid.

Further, by moving up and down the moving part 37 of the diaphragm 30, the pressure direction in the channel 111 is changed to cause the packing member 20 to flow. In order to more effectively control the pressure direction, 30 are provided with an upper partition plate 39 at the upper portion of each of them.

More specifically, the upper partition plate 39 is provided in a seating portion 35 of each zone of the diaphragm 30 and includes a planar pressing portion 391, And a bolt engaging portion 393 protruding from the lower portion of the pressing portion 391 and inserted into the hole 33 of the diaphragm 30 is formed.

More specifically, the upper partition plate 39 is provided on the upper portion of the diaphragm 30 so that the pressing portion 391 is positioned on the seating portion 35. When the fluid portion 37 rises, The pressure portion 391 of the upper partition plate 39 rises and the pressure direction in the closed pipeline 111 is upward so that when the fluid portion 37 descends, 39 are lowered to descend the pressure direction in the pipeline 111 and the suction packing 21 or the discharge packing 23 is caused to flow in accordance with the change in the pressure direction so that the suction hole 115A and the discharge hole 117A. This operation will be described in more detail below with reference to FIG.

The bolt coupling portion 393 of the upper partition plate 39 sequentially passes through the hole 33 and the insertion hole 131A of the diaphragm 30 and is inserted into the push portion 43 of the triangular frame 40 And is coupled to the provided interpolation section 433,

A tapping bolt 45 is provided at a lower portion of the triangular frame 40 so that the tapping bolt 45 penetrates the inner part 433 and is inserted into the bolt coupling part 393 of the upper partition plate 39 The upper partition plate 39, the diaphragm 30, the lower main body 13 and the triangular frame 40 are fixed by being fastened to the bolt coupling holes 393A.

As a result, the flow portion 37 and the upper partition plate 39 of the diaphragm 30 are moved up and down by the upward and downward movement of the triangular frame 40 to change the pressure direction in the channel 111, So that the pump can be operated.

A bearing 47 and a bearing bolt 471 for fixing the bearing 47 are provided inside the lower portion of the triangular frame 40 so that the triangular frame 40 can be moved up and down smoothly by a driving means It is preferable to allow the user to proceed to the next step.

The bolt engagement portion 393 of the upper partition plate 39 and the inner hole 33 of the diaphragm 30 and the inner insertion portion 433 of the triangular frame 40 are moved upward and downward, There is a problem that the upper partition plate 39 idles or is unable to transmit the pressing force properly when it is moved up and down.

Therefore, in the diaphragm pump assembly (A) according to the present invention, the bolt coupling portion 393 is formed into a D-cut non-circular shape having a straight portion 393B, and the bolt coupling portion 393 is inserted And the inner hole 33 and the inner portion 433 are formed in the same D-cut non-circular shape as the bolt coupling portion 393 to prevent idle rotation of the upper partition plate 39, It is preferable that the information is transmitted so as to be accurately transmitted.

3 shows an embodiment of the diaphragm pump assembly A according to the present invention. As shown in FIG. 3A, when the triangular frame 40 is lowered, The moving part 37 descends so that the upper partition plate 39 descends and the pressing force in the pipeline 111 above the upper partition plate 39 faces downward. The suction opening and closing part 211 of the suction packing 21 provided at the lower part of the upper body 11 is pressed down by the pressure and the suction hole 115A is opened so that the fluid flows into the pipeline 111 .

3 (B), when the triangular frame 40 is lifted up, the diaphragm 30 is lifted up to the upper portion of the upper main body 11 through the discharge hole 117A. The upper partition plate 39 rises and the pressing force in the pipeline 111 is changed to the upper direction. The discharge opening 231 of the discharge packing 23 coupled to the upper surface of the upper main body 11 rises and the discharge opening 231 of the discharge seal 23 is lifted up, So that the fluid can be discharged through the discharge hole 117A by opening the discharge port 117A.

As the operation repeatedly occurs, the diaphragm pump assembly 30 operates according to the present invention. As described above, as the suction hole 115A and the discharge hole 117A are formed in a circular shape, The durability of the packing member 20 can be improved because the wear of the packing member 20 is less than that of the prior art using the pump.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Changes and substitutions are to be construed as falling within the scope of protection of the present invention.
