[0002] The hydraulic control system of a conventional hydraulic diaphragm pump is mainly controlled by the linkage of three valves: a safety valve, an oil replenishing valve, and a limit valve. In particular, in the process of exhausting and replenishing oil at the initial stage of pump startup, a more traditional operation method is usually adopted. When the pump starts, the exhaust valve and the oil replenishing valve will be activated at the same time to exhaust the air accumulated in the pump cavity and replenish the necessary oil. In this process, the exhaust valve is responsible for gradually exhausting the air in the pump cavity, while the oil replenishing valve is responsible for replenishing oil into the pump cavity to ensure that the pump can smoothly enter the normal operating state. Although the existing oil tank adjustment control system will start the exhaust valve and the oil replenishing valve for exhaust and oil replenishment at the initial stage of pump startup, in actual operation, the efficiency and effect of this process are not ideal.

DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] See also Figure 1-9 , the present invention provides a technical solution: An integrated regulating and controlling oil tank comprises a diaphragm pump 1 and a safety valve 6 arranged inside the diaphragm pump 1; the inner cavity of the diaphragm pump 1 is provided with a quick exhaust valve 2 for quick exhaust of gas and a quick oil replenishing valve 3 for quick replenishment of oil; the inner cavity of the diaphragm pump 1 is also provided with an exhaust valve for uniform exhaust of gas and an oil replenishing valve for uniform replenishment of oil; a manual valve 4 for controlling the opening or closing of the quick exhaust valve 2 and the quick oil replenishing valve 3 is also provided on one side of the quick exhaust valve 2; a pressure device 5 is provided at the bottom of the inner cavity of the diaphragm pump 1, and the pressure device 5 is used to provide positive pressure or negative pressure to the inner cavities of the quick exhaust valve 2 and the quick oil replenishing valve 3; An air intake end 23 is provided at the top end of the quick exhaust valve 2, and an air exhaust end 21 is provided at the bottom end of the quick exhaust valve 2. A speed regulating mechanism 22 is provided at one end of the air exhaust end 21. The speed regulating mechanism 22 is used to adjust the speed at which the gas is discharged to the outside through the quick exhaust valve 2. An air intake hole 231 is provided on the outside of the air intake end 23. When sufficient negative pressure is generated inside the air intake end 23, the air intake hole 231 opens, and when positive pressure is generated inside the air intake end 23, the air intake hole 231 closes.

[0019] In this embodiment, please refer to Figure 4 The pressure device 5 includes a pressure seat 51, which is provided with two pressure chambers, and a plunger 52 is arranged inside the pressure chamber. When the plunger 52 moves, the pressure in the inner cavity of the pressure seat 51 changes. A connecting valve 53 is arranged on both sides of the pressure seat 51, and a connecting pipe 54 is arranged on both sides of the connecting valve 53. The pressure seat 51 is connected to the inner cavity of the quick exhaust valve 2 and the quick oil replenishment valve 3 through the connecting valve 53 and the connecting pipe 54. In this embodiment, the movement of the plunger 52 is controlled by rotating the driving disk 41. When the plunger When 52 moves, the space in the inner cavity of the pressure seat 51 changes, and the plunger 52 moves backward, so that the space in the inner cavity of the pressure seat 51 becomes larger. Therefore, under the action of negative pressure, the air inside the quick exhaust valve 2 and the quick oil replenishing valve 3 is absorbed through the connecting valve 53 and the connecting pipe 54, so that negative pressure is generated inside the quick exhaust valve 2 and the quick oil replenishing valve 3. Therefore, under the action of negative pressure, the discharge speed of the air hidden in the inner cavity of the diaphragm pump 1 through the quick exhaust valve 2 can be further increased, and negative pressure can be generated through the quick oil replenishing valve 3 to increase the oil replenishing speed.

[0020] In this embodiment, please refer to Figure 5 The connecting valve 53 includes a tube body 531, and both sides of the tube body 531 are provided with flow holes 534 connected to the connecting pipe 54. The inner cavity of the tube body 531 is provided with two blocking rings 532, and a second spring 533 is provided between the two blocking rings 532, wherein one blocking ring 532 is used to block the flow hole 534. In this embodiment, when negative pressure is generated in the inner cavity of the pressure seat 51, the blocking ring 532 can be pushed to move away from the flow hole 534 under the action of the negative pressure, and the second spring 533 can be squeezed and deformed. At this time, the gas can be transmitted through the flow hole 534, and the quick exhaust valve 2 is absorbed by the pressure seat 51. , the gas in the inner cavity of the quick exhaust valve 2 and the quick oil replenishing valve 3 causes negative pressure to be generated in the inner cavity of the quick exhaust valve 2 and the quick oil replenishing valve 3. After the gas enters the pressure seat 51, the pressure in the inner cavity of the pressure seat 51 returns to normal, so that the second spring 533 loses pressure rebound, and the blocking ring 532 returns to its original position and blocks the flow hole 534 again. After the pressure seat 51 absorbs the gas in the inner cavity of the quick exhaust valve 2 and the quick oil replenishing valve 3, the gas in the pressure seat 51 is prevented from flowing back into the inner cavity of the quick exhaust valve 2 and the quick oil replenishing valve 3 through the connecting valve 53 and the connecting pipe 54, so that the quick exhaust valve 2 and the quick oil replenishing valve 3 generate sufficient negative pressure for quick oil replenishment and quick exhaust.

[0021] In this embodiment, please refer to Figure 1The inner cavity of the suction end 23 is provided with a moving ring 232, and an installation groove 233 is opened on the outer side of the moving ring 232. The inner cavity of the installation groove 233 is provided with a sealing plug 235, and the sealing plug 235 is arranged in the inner cavity of the suction hole 231. In this embodiment, when the inner cavity of the quick exhaust valve 2 generates negative pressure, the inner cavity of the quick exhaust valve 2 generates suction, and the moving ring 232 moves backward under the action of the suction force, and drives the sealing plug 235 to move backward, so that the suction hole 231 is no longer blocked, so that the valve of the quick exhaust valve 2 is opened, and the gas hidden in the diaphragm pump 1 can enter the quick exhaust valve 2 through the suction hole 231, and then be discharged to the outside through the quick exhaust valve 2. When the inner cavity of the quick exhaust valve 2 generates positive pressure, the moving ring 232 is pushed to move forward, so that the sealing plug 235 blocks the suction hole 231 again, so that the quick exhaust valve 2 is closed.

[0022] In this embodiment, please refer to Figure 1 , the inner cavity of the mounting groove 233 is provided with a first spring 234, one end of the first spring 234 is connected to the sealing plug 235, and the end of the sealing plug 235 in contact with the suction hole 231 is set to a rounded corner. In this embodiment, since one end of the sealing plug 235 is set to a rounded corner, when the suction force is large enough, the sealing plug 235 moves toward the mounting groove 233 under the interaction force with the inner wall of the suction hole 231, and squeezes the first spring 234 to cause it to deform. Therefore, the valve of the quick exhaust valve 2 will only be opened when sufficient negative pressure is generated in the inner cavity of the quick exhaust valve 2, thereby preventing the negative pressure generated during the backward movement of the plunger 52 from absorbing the oil into the inner cavity of the pressure seat 51.

[0023] In this embodiment, please refer to Figure 1 The speed regulating mechanism 22 includes a driven sprocket 221 and a fixed sleeve 222. The driven sprocket 221 is arranged on the outside of the fixed sleeve 222. The inner wall of the fixed sleeve 222 is respectively provided with a positioning plate 224 fixed to the inner wall of the fixed sleeve 222 and a speed regulating plate 223 that can rotate along the inner wall of the fixed sleeve 222. The positioning plate 224 and the corresponding surface of the speed regulating plate 223 are transitionally matched. The inner sides of the speed regulating plate 223 and the positioning plate 224 are both provided with the same number of sieve plates 225. In this embodiment, by controlling the rotation of the speed regulating plate 223, the speed regulating plate 223 can be made to rotate. The position of the sieve plate 225 arranged on the inner side thereof moves. Since the positioning plate 224 remains fixed, the overlapping area of ​​the two groups of sieve plates 225 changes. Since the corresponding surfaces of the speed regulating plate 223 and the positioning plate 224 are transitionally matched, by controlling the overlapping area of ​​the two groups of sieve plates 225, the speed at which the liquid and fluid pass through the speed regulating mechanism 22 can be controlled. Therefore, when the diaphragm pump 1 is performing rapid exhaust and oil replenishment, the circulation speed of the gas and fluid can still be further adjusted through the speed regulating mechanism 22, thereby further improving the flexibility and adaptability of the device.

[0024] In this embodiment, please refer to Figure 1The manual valve 4 includes a driving disk 41 and a partition 43. The surface of the partition 43 is provided with a threaded groove. One end of the driving disk 41 is provided with a threaded rod 42 adapted to the threaded groove. One end of the threaded rod 42 passes through the active sprocket 44 and is connected to one side of the plunger 52. In this embodiment, the driving disk 41 is controlled to rotate by external force, so that the threaded rod 42 can move along the inner wall of the threaded groove, and by controlling the rotation direction of the driving disk 41, the threaded rod 42 can move backward to drive the plunger 52 to move backward, thereby generating a negative pressure in the inner cavity of the quick exhaust valve 2 and the quick oil replenishment valve 3. When the threaded rod 42 drives the plunger 52 to move forward, a positive pressure can be generated inside the quick exhaust valve 2 and the quick oil replenishment valve 3.

[0025] In this embodiment, please refer to Figure 1 A second magnetic circle 227 is provided on the outer side of the speed regulating plate 223, and a first magnetic circle 226 that attracts the speed regulating plate 223 is provided on the inner wall of the driven sprocket 221. In this embodiment, the position of the first magnetic circle 226 is changed by controlling the rotation of the driven sprocket 221, and the suction end 23 is rotated under the action of suction, thereby adjusting the circulation speed of the liquid and the gas.

[0026] In this embodiment, please refer to Figure 1 The threaded rod 42 can move through the driving sprocket 44 and can drive the driving sprocket 44 to rotate. Two chains 45 are meshed on the outer side of the driving sprocket 44, and one end of the inner wall of the chain 45 is meshed with a driven sprocket 221. In this embodiment, the driving sprocket 44 is slightly rotated by controlling the driving disk 41 to rotate slightly. Through the transmission of the chain 45, the two driven sprockets 221 are rotated at the same time, thereby simultaneously controlling the flow speed of the liquid and fluid in the quick exhaust valve 2 and the quick oil replenishment valve 3.

[0027] In this embodiment, please refer to Figure 1 The inner cavity of the exhaust end 21 is provided with a one-way valve 211, the top end of the quick oil replenishing valve 3 is the oil replenishing end, and the bottom end is the oil suction end, and the oil replenishing end is also provided with the same one-way valve 211. In this embodiment, by providing the one-way valve 211, when the inner cavity of the quick exhaust valve 2 generates a negative pressure, it is prevented from sucking the outside air into the inner cavity of the quick exhaust valve 2. By providing the one-way valve 211 at the oil replenishing end of the quick oil replenishing valve 3, it is prevented from absorbing the oil located inside the diaphragm pump 1 when the negative pressure is generated in the inner cavity of the quick exhaust valve 2.

[0028] Working principle of the present invention: Step 1, rotate the drive disk 41 through external force, and drive the threaded rod 42 through the drive disk 41 to rotate along the threaded groove opened on the surface of the partition plate 43. Since the outer side of the threaded rod 42 is adapted to the threaded groove, the threaded rod 42 can be moved backward along the threaded groove by controlling the rotation direction of the drive disk 41, and the plunger 52 is driven to move backward by the threaded rod 42. When the plunger 52 moves backward, the space in the inner cavity of the pressure seat 51 becomes larger, so that negative pressure is generated in the inner cavity of the pressure seat 51, and under the action of negative pressure, the gas in the quick exhaust valve 2 and the quick oil replenishment valve 3 is extracted, so that negative pressure is generated inside the quick exhaust valve 2 and the quick oil replenishment valve 3. Under the action of negative pressure, suction is generated inside the quick exhaust valve 2. Under the action of suction, since the connection end of the sealing plug 235 and the suction hole 231 is set to a rounded corner, at the suction end 2 After the suction force is generated in the inner cavity of the air intake end 23, the movable ring 232 moves backward under the suction force of the inner cavity of the air intake end 23, and the sealing plug 235 slides out of the air intake hole 231, so that the passages of the quick exhaust valve 2 and the quick oil replenishing valve 3 are opened, and the gas and oil can flow through the quick exhaust valve 2 and the quick oil replenishing valve 3 respectively, which accelerates the discharge of air and the replenishment of oil in the pump cavity, and significantly shortens the pump adjustment time. When the pump enters normal operation, the plunger 52 moves forward and returns to its original position by rotating the driving disk 41 in the reverse direction, and the gas is injected into the inner cavity of the quick exhaust valve 2 and the quick oil replenishing valve 3 again, so that the inner cavity of the quick exhaust valve 2 and the quick oil replenishing valve 3 generates positive pressure, so that the movable ring 232 moves forward, and the sealing plug 235 blocks the air intake hole 231 again, and the quick exhaust valve 2 and the quick oil replenishing valve 3 are closed accordingly, and the pump enters normal operation state; Step 2, when the plunger 52 moves backward, the inner cavity of the pressure seat 51 generates negative pressure, and the blocking ring 532 moves backward under the action of the negative pressure, and the blocking ring 532 moves backward to squeeze the second spring 533 to cause it to deform, and the blocking ring 532 moves backward and leaves the flow hole 534. At this time, the air in the quick exhaust valve 2 and the quick oil replenishment valve 3 can be sucked into the inner cavity of the pressure seat 51 through the flow hole 534. As the gas enters the inner cavity of the pressure seat 51, the air pressure inside the pressure seat 51 returns to normal. At this time, the second spring 533 loses pressure and rebounds, thereby lifting the blocking ring 532 to make it return to its original position. When the blocking ring 532 returns to its original position, it will be re- Block the flow hole 534 to prevent the gas in the pressure seat 51 from flowing back into the inner cavity of the quick exhaust valve 2 and the quick oil replenishment valve 3, so that the inner cavity of the quick exhaust valve 2 and the quick oil replenishment valve 3 maintains sufficient air pressure. When the valve at the suction end 23 is opened, the gas inside the diaphragm pump 1 can enter the suction end 23 through the suction hole 231 under the action of air pressure, so that at the moment of opening the quick exhaust valve 2, the air hidden inside the diaphragm pump 1 can be quickly extracted. Similarly, at the moment of opening the valve of the quick oil replenishment valve 3, the external oil can be quickly sucked in through the oil suction end and discharged into the interior of 1 through the oil replenishment end, thereby further accelerating the discharge of air from the inner cavity of the diaphragm pump 1 and the replenishment of oil; Step three, after the quick exhaust valve 2 and the quick oil replenishment valve 3 are opened, the exhaust speed and the oil replenishment speed of the inner cavity of the diaphragm pump 1 are increased, at this time, the driving disc 41 is controlled to rotate slightly, and the driving disc 41 rotates to drive the active sprocket 44, and the active sprocket 44 drives the chain 45 to rotate, and the chain 45 drives the two driven sprockets 221 to rotate. Since the driven sprocket 221 is provided with a first magnetic ring 226 on the inner side, and the outer side of the speed regulating plate 223 is provided with a second magnetic ring 227 that attracts the first magnetic ring 226, the position of the first magnetic ring 226 is changed by the rotation of the driven sprocket 221, and the second magnetic ring 227 drives the speed regulating plate 223 to rotate under the action of suction. A plurality of sieve plates 225 are arranged on the inner side of the positioning plate 224. When the speed regulating plate 223 rotates, the position of the positioning plate 224 remains unchanged, thereby changing the overlapping area of ​​the two groups of sieve plates 225. When the overlapping area of ​​the two groups of sieve plates 225 gradually becomes smaller through the rotation of the speed regulating plate 223, the gap between the sieve plates 225 gradually becomes smaller, thereby slowing down the speed at which liquid or fluid passes through. When the overlapping area of ​​the two groups of sieve plates 225 increases, the gap between the sieve plates 225 becomes larger, thereby accelerating the flow speed of the liquid and fluid. Therefore, by controlling the rotation of the driving disk 41 in a small range, the exhaust speed and oil replenishment speed of the inner cavity of the diaphragm pump 1 can be further adjusted, so that the exhaust and oil replenishment of the diaphragm pump 1 can be more finely controlled.
