Description

Technical Field

[0001] This utility model relates to the technical field of valve devices, and more specifically, to a separate intake regulating valve. Background Technology

[0002] A variable frequency (VFD) air compressor is a type of air compressor that can operate at adjustable speed. Its working principle involves adjusting the voltage frequency of the motor via a frequency converter, thereby changing the motor's speed. A VFD air compressor can adjust its operating speed according to actual needs, thus achieving flexible control over pressure and flow. It can adjust its operating speed in real time according to load changes, providing constant output pressure while maintaining high energy efficiency. VFD air compressors have a wide range of applications and can adapt to the needs of various working conditions.

[0003] In oil-injected screw air compressors, the oil-gas separation system is a crucial component. Its main function is to reduce oil consumption and ensure the oil content of the compressed air remains within a certain range. The oil-gas separation system generally includes two steps: coarse separation and fine separation. Currently, air compressor manufacturers focus primarily on the effectiveness of fine separation while neglecting the role of coarse separation. While manufacturers continuously improve their technology to reduce the oil content of compressed air, and users select high-quality oil-gas separators to ensure the compressed air meets predetermined performance standards, in practical applications, excessive oil content or pressure differentials in the exhaust can still occur. In severe cases, this can even lead to oil-gas separator combustion and explosion. Therefore, the lack of coarse separation or its ineffectiveness can result in a bottleneck effect in fine separation.

[0004] Existing variable frequency air compressors suffer from variations in exhaust volume due to different operating conditions, while the intake passage generally remains unchanged. This results in an intake velocity that is not the ideal velocity for coarse separation, leading to extremely poor separation performance. Furthermore, the use of different pressure range settings means that even with the same displacement and intake passage, varying intake pressures cause continuous changes in intake air velocity, further deviating from the optimal coarse separation velocity.

[0034] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in still another embodiment,” all of which may refer to one or more of the same or different embodiments according to this disclosure.

[0035] This utility model provides a separation intake regulating valve, which can be installed on the side of a barrel-shaped device, such as on the side of a gas storage tank, or on a tubular device, such as on a gas transmission pipeline. This embodiment is used in the coarse separation stage of an oil-gas separation system. By controlling the intake port diameter, the intake air velocity and flow rate are adjusted, so that the coarse separation speed remains at a suitable value when the displacement or pressure changes due to operating conditions.

[0036] like Figures 1-6 As shown, the separate intake regulating valve in this embodiment includes a valve seat 10 and a controller. The valve seat 10 includes a valve seat body 1 and a base 2. The valve seat 10 is mounted on the side of, for example, a gas storage tank 20 via the base 2, or it can be mounted on the pipeline via the base 2. Here, the base 2 is matched and installed with the through hole on the side of the gas storage tank 2 so that gas can enter the gas storage tank 2 through the separate gas regulating valve.

[0037] Specifically, the valve seat body 1 includes an upper connecting plate 11, a lower connecting plate 12, and a housing. The upper connecting plate 11 is used to connect with an external gas pipeline, the lower connecting plate 12 is connected to the base 2, and the housing is connected to the upper connecting plate 11 and the lower connecting plate 12. A driving device is provided on the outside of the housing, and the housing has an opening 1. An adjustment device connected to the driving device is provided on the inside of the opening to adjust the opening degree.

[0038] Specifically, the housing includes a first housing 13 and a second housing 14. The first housing 13 is disposed between the upper connecting plate 11 and the lower connecting plate 12, and the second housing 14 is disposed below the lower connecting plate 12. The first housing 13 and the second housing 14 are connected to form the housing. The second housing 14 has an opening 141. Gas from the external gas pipeline enters the first housing 13 through the upper connecting plate 11 and enters the second housing 14 through the lower connecting plate 12. Finally, the gas is discharged into the gas storage tank 20 from the opening 141 of the second housing 14.

[0039] Furthermore, a drive device 15 is provided on the outer surface of the first housing 11, and the drive device 15 may be, for example, a servo motor; a worm gear 16 is provided inside the first housing 13, and the extension direction of the worm gear 16 is perpendicular to the length direction of the first housing 13. The first end of the worm gear 16 passes through one side surface of the first housing 11 and is connected to the drive device 15, and its second end protrudes from the other side surface of the first housing 11. The drive device 15 can drive the worm gear 16 to reciprocate in its extension direction.

[0040] Furthermore, a valve plate 17 is provided inside the second housing 14. The first end of the valve plate 17 is rotatably connected to the inner surface of the second housing 14, and the opening 141 can be opened or closed by rotating the valve plate 17. Specifically, a rotating shaft 18 is provided on the inner surface of the second housing 14, and the first end of the valve plate 17 is sleeved on the rotating shaft 18, thereby allowing the valve plate 17 to rotate around the rotating shaft 18. Preferably, a return spring 19 is provided on the rotating shaft 18, which facilitates the return of the valve plate 17 to the closed state of the opening 141. In this embodiment, the air intake is adjustable as the valve plate 17 rotates. For example, the valve plate 17 can be adjusted to the required opening degree by the drive device 15, realizing the function of a variable air intake passage.

[0041] In this embodiment, a plurality of first connecting seats 171 are provided on the side of the valve plate 17. The first connecting seats 171 are sleeved on the rotating shaft 18, so that the valve plate 17 can rotate relative to the rotating shaft 18 through the first connecting seats 171.

[0042] The drive device 15 in this embodiment is controlled by the controller. By calculating the intake air velocity required based on the current displacement and intake pressure, the opening of the valve plate 17 is adjusted so that the intake air velocity reaches the optimal intake air velocity, thereby achieving the best coarse separation effect.

[0043] Furthermore, the second end of the valve plate 17 is connected to the worm gear 16 via a connecting rod 21. Specifically, the first end of the connecting rod 21 is connected to the middle of the worm gear 16, and its second end is connected to the second end of the valve plate 17, so that the reciprocating motion of the worm gear 16 can drive the movement of the connecting rod 21. When the worm gear 16 moves along its extension direction, the connecting rod 21 can drive the second end of the valve plate 17 to rotate relative to the second housing 14, thereby opening or closing the opening 141.

[0044] Specifically, a through hole 161 is provided in the middle of the worm gear 16, and the first end of the connecting rod 21 extends into the through hole 161 and is rotatably disposed in the through hole 161 through a first connecting shaft 162. Here, the first end of the connecting rod 21 is rotatably connected to the middle of the worm gear 16 through the first connecting shaft 162.

[0045] Furthermore, a second connecting seat 172 is provided on the surface of the valve plate 17, and a second connecting shaft 173 is provided on the second connecting seat 172. The second end of the connecting rod 21 is rotatably connected to the second connecting seat 172 through the second connecting shaft 173.

[0046] Furthermore, the second housing 14 passes through the base 2, and the orientation of the opening 141 forms a predetermined angle with the lower connecting plate 12. For example, the second housing has a bottom plate 142, which is inclined relative to the lower connecting plate 12 and has a predetermined angle with the lower connecting plate 12. The predetermined angle can be, for example, 3°-8°, preferably 5°. The opening 141 is located on the side of the second housing 14. After the gas enters the second housing 14 from the first housing 13, it impacts the bottom plate 142 and is then input into the gas storage tank 20 through the side opening 141, thus achieving the effect of tangential air intake.

[0047] In addition, the base 2 is provided with a sloping part 22, which has the same degree of inclination as the base plate 142, and the sloping part 22 cooperates with the opening 141 on the second housing 14.

[0048] This invention uses a variable intake passage to ensure optimal intake airflow rate under different displacement and pressure variations, thus ensuring the coarse separation process reaches its best state.
