A first steel wire ring 4 and a second steel wire ring 7 are respectively disposed at the left and right ends of the lower side of the vacuum membrane upper pressure plate 3. The lower sides of the first steel wire ring 4 and the second steel wire ring 7 are in contact with the upper surface of the vacuum membrane body 10. The first steel wire ring 4 and the second steel wire ring 7 are circular metal parts used to fasten the vacuum membrane body 10 within the vacuum membrane upper pressure plate 3 and the vacuum membrane lower pressure plate 9, preventing vacuum... When working, the outer end of the membrane body 10 is separated from the upper vacuum membrane pressure plate 3 and the vacuum membrane body 10. The upper vacuum membrane pressure plate 3 and the lower vacuum membrane pressure plate 9 are threadedly connected to a double P-type sealing strip fixing bolt 5. The double P-type sealing strip fixing bolt 5 is used to fix the upper vacuum membrane pressure plate 3, the lower vacuum membrane pressure plate 9 and the double P-type sealing strip body 8 together. The bottom outer side of the double P-type sealing strip fixing bolt 5 is threadedly connected to a sealing strip pressure ring 6.

The cavity formed between the vacuum valve seat 1 and the vacuum membrane body 10, the double P-type sealing strip body 8 seals the connection between the lower vacuum membrane pressure plate 9 and the vacuum valve seat 1.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7As shown, the vacuum membrane body 10 and the driving membrane body 11 are attached together at their middle parts. A lower membrane center clamping plate 12 is provided on the lower side of the middle part of the vacuum membrane body 10, and an upper membrane center clamping plate 18 is provided on the upper side of the middle part of the driving membrane body 11.

The function of the fourth steel wire ring 15 and the fifth steel wire ring 16 is to firmly fix the middle parts of the vacuum membrane body 10 and the driving membrane body 11 together by pressure. When the vacuum diaphragm flushing valve is running, the middle parts of the vacuum membrane body 10 and the driving membrane body 11 will move up and down inside the flushing valve. Therefore, the lower membrane center clamping plate 12 and the upper membrane center clamping plate 18 are used to fix the middle parts of the vacuum membrane body 10 and the driving membrane body 11 together. A vacuum suction tube 14 is provided through the middle of the lower membrane center clamping plate 12 and the upper membrane center clamping plate 18. The bottom of the vacuum suction tube 14 is located in the cavity formed by the vacuum valve seat 1 and the vacuum membrane body 10, and the outer end of the driving membrane body 11 is located in the cavity formed by the vacuum valve seat 1 and the vacuum membrane body 10.

A circular metal part is provided in the contact surface between the lower outer end of the drive membrane bracket 21 and the drive membrane body 11 to prevent the outer end of the drive membrane body 11 from detaching from the drive membrane fixing bolt 2 and the drive membrane bracket 21.

[0026] like Figure 1 , Figure 2 , Figure 8As shown, a pressure gauge 20 is fixedly connected to the outer end of the upper surface of the vacuum valve seat 1. The pressure gauge 20 is used to monitor the internal air pressure of the vacuum diaphragm flushing valve. The right end of the drive diaphragm support 21 is connected through to the bottom of the first steel wire hose 23. The upper end of the first steel wire hose 23 is provided with a hose clamp 22 for controlling the inlet and outlet. The upper side of the vacuum suction tube 14 is fixedly connected to the lower side of the second steel wire hose 24. A sliding bearing body 26 is provided through to the outer side of the upper end of the vacuum suction tube 14. The bottom surface of the sliding bearing body 26 is fixedly connected to the drive diaphragm support 21. A sliding bearing fixing bolt 25 is threaded on the upper end of the sliding bearing body 26. The sliding bearing fixing bolt 25 fixes the sliding bearing body 26 to the drive diaphragm support 21. A mountain-shaped sealing ring 27 is provided on the outer side of the bottom of the sliding bearing body 26. The mountain-shaped sealing ring 27 seals the sliding bearing body 26. An O-ring 28 is provided on the lower side of the drive diaphragm support 21. The O-ring 28 seals the connection between the sliding bearing body 26 and the drive diaphragm support 21.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cover 29 is bolted to the top of the vacuum valve seat 1. The drive diaphragm support 21 is located above the vacuum valve seat 1, so the cover 29 is fixed to the drive diaphragm support 21. The cover 29 protects the hose clamp 22, the second steel wire hose 24, and the sliding bearing body 26. The vacuum valve seat 1 is composed of a base plate and several sets of connecting plates on the side. The connecting plates on the side of the vacuum valve seat 1 fix the vacuum valve seat 1 to the cover 29. The grid at the bottom of the side of the vacuum valve seat 1 is an air inlet mesh. A valve body protective cover 30 is provided on the lower side of the vacuum valve seat 1. The valve body protective cover 30 protects the vacuum diaphragm flushing valve.

[0028] It should be noted that, in use, this vacuum diaphragm flushing valve for flushing sediment in a storage tank, when the pressure in the driving membrane chamber and the water storage chamber is equal, the driving membrane body 11, the lower membrane center clamping plate 12, the third steel wire ring 13, the vacuum suction tube 14, the fourth steel wire ring 15, the fifth steel wire ring 16, the membrane center clamping bolt 17, and the membrane center upper clamping plate 18 droop under their own weight, causing the double P-type sealing strip body 8 to be in close contact with the bottom plate of the vacuum valve seat 1. When the storage tank is filled with water and the vacuum flushing system is satisfied... When the system starts, the vacuum flushing system is activated. At this time, when the external vacuum source and vacuum pump system evacuate the vacuum suction tube 14, negative pressure is generated in the water storage chamber. At this time, the external atmospheric pressure plays a role in pressing the vacuum membrane body 10 firmly against the base plate of the vacuum valve seat 1. The base plate of the vacuum valve seat 1 is sealed with sealant to the concrete installation surface. The air in the water storage chamber is extracted. At this time, the water in the water storage chamber rises as the air above it is discharged until the set water level is reached, and the external vacuum source and vacuum pump stop working.

[0029] When the storage tank is emptied, and the sediment at the bottom of the storage tank needs to be flushed, the vacuum flushing system is restarted. The vacuum pump evacuates the membrane cavity formed by the driving membrane body 11 in the vacuum valve seat 1. When the negative pressure in the driving membrane cavity formed by the driving membrane body 11 in the vacuum valve seat 1 is equal to the negative pressure in the water storage chamber, the driving membrane body 11 drives the lower clamping plate 12, the third steel wire ring 13, the vacuum suction tube 14, the fourth steel wire ring 15, the fifth steel wire ring 16, the clamping bolt 17 of the membrane center clamping plate, and the upper clamping plate 18 of the membrane center to move upward until the double P-type sealing strip body 8 is forced to separate from the bottom plate at the bottom of the vacuum valve seat 1. This causes a large amount of external air to quickly fill the water storage chamber. At this time, the water in the water storage chamber suddenly loses its upward suction and falls freely. A very strong jet is generated at the drain outlet at the bottom of the water storage chamber that connects to the flushing corridor in the storage tank, which strongly and effectively flushes the sediment at the bottom of the storage tank corridor. The jet can travel up to 500 meters.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
