Description

Technical Field

[0001] This application belongs to the field of hydraulic valve assembly technology, specifically relating to a shock wave discrete rotary valve. Background Technology

[0002] Regarding discrete flow transmission and control technology, existing experts have proposed that high-speed pulse flow can be transmitted in pipelines using a quasi-rigid frequency of 20 MPa oil. However, there is little discussion on how to specifically control or eliminate the impact of pulses on hydraulic actuators.

[0003] Among the existing patented technologies, for example, application number 201810627308.7, entitled "Design Method and Device for Eliminating Hydraulic Pulsation," discloses a device specifically designed to eliminate hydraulic pulsation. It discloses a gear pump device, a vane pump device, and a plunger pump device for eliminating hydraulic pulsation. In one of the vane pump devices, several individual vane pumps are connected in series. Each vane pump includes a stator and a rotor. The stator's inner cavity within the pumping angle range is a perfect circle. When the vanes are within the pumping angle range, the through-holes and channels are offset, preventing communication between the channels and the vane cavity. When the vanes are outside the pumping angle range, they retract into the vane cavity, and the through-holes and channels connect, keeping the rotor's inner cavity connected. This ensures that the volume change of the cavity between the rotor and stator is equal per unit time, thereby achieving stable oil supply when eliminating hydraulic pulsation. However, this method requires at least two individual vane pumps connected in series, and it demands high precision in controlling the pump angle. This means that when the displacement of one individual vane pump decreases, the displacement of another must increase precisely to eliminate pulsation. If the pump angle distribution or displacement curve is improperly designed, residual superimposed pulsation may still occur. Furthermore, the vanes require through-holes, which can lead to leakage during operation due to machining precision issues, negatively impacting the volumetric efficiency within the pump angle. Therefore, developing a device or pulsation suppressor to eliminate shock waves and smooth pulsation impacts, as well as a method for calculating discrete pulse flow rate, remains a challenging problem. Utility Model Content

[0004] This application provides a shock wave discrete rotary valve to solve at least one of the above-mentioned technical problems.

[0005] The technical solution adopted in this application is as follows:

[0006] A shock wave discrete rotary valve includes a valve body, a valve core, a shock wave damper, and a sensor; the valve body includes a valve cover and a valve seat symmetrically connected; the valve cover and valve seat have a support groove, a cavity, an oil inlet channel, a recovery channel, and an oil outlet channel formed therein, and a bearing is installed in the support groove;

[0007] The valve core includes a rotating shaft, a rotary disk, and multiple rotating cups disposed within a cavity; both ends of the rotating shaft are connected to bearings in a support groove; the rotary disk is fixedly connected to the middle of the rotating shaft with the rotating shaft as its axis, and multiple rotating cups are equally spaced and connected to the outer periphery of the rotary disk; the sensor is disposed outside the valve cover and / or valve seat that enclose the rotating cup cavity of the valve body;

[0008] The centerlines of the inlet and outlet flow channels are collinear and tangent to the movement trajectory of the center of the rotating cup; the opening of the rotating cup at the tangent point faces the inlet flow channel, and a recovery channel is opened at the tangent point along the radial direction of the valve core, with a shock wave buffer installed at the bottom of the recovery channel.

[0009] Oil containing shock waves impacts the rotating cup through the inlet channel, causing the rotating cup to drive the valve core to rotate around the rotating shaft. The shock waves expand rapidly inside the rotating cup and splash out. The splashed oil enters the recovery channel through the centrifugal force of the rotating cup, and the shock wave energy of this part of the oil is absorbed by the shock wave buffer at the bottom of the recovery channel. The remaining oil in the rotating cup is partly thrown into the outlet channel by the impact rotation and centrifugal force of the rotating cup, and partly enters the next impact cycle with the rotation of the rotating cup.

[0010] The recovery channel has an initial section connected to the shock wave buffer. The rotation axis of the initial section is perpendicular to or at an angle of no more than 120° with the rotation axis of the oil inlet channel. This allows the rotating cup to rotate after being impacted by the shock wave liquid and be thrown into the initial section of the recovery channel. Alternatively, when the rotating cup rotates to a range where the angle between it and the rotation axis of the oil inlet channel is 120°, the shock wave liquid reflected by the rotating cup can still be thrown into or splashed out to the initial section of the recovery channel. This allows the shock wave energy of the shock wave liquid to be absorbed by the shock wave buffer at the bottom of the initial section of the recovery channel. After being buffered and delayed, the shock wave liquid can return to the area between the rotating cups through the initial section of the recovery channel and flow into the oil outlet channel as the rotating cup rotates.

[0011] The rotation space of the rotating cup and the rotary table is enveloped by the cavity, and the envelopment gap is no more than 1mm, so as to ensure that the excess oil after the shock wave is expanded by the spherical rotating cup is absorbed by the recovery channel opened in the radial direction of the valve core. The remaining oil is partially thrown into the oil outlet channel by the centrifugal force of the rotating cup, and partially enters the next impact cycle with the rotation of the rotating cup.

[0012] The recovery channel also includes a subsequent section, which is connected to the starting section; the subsequent section includes a first subsequent section and a second subsequent section that are perpendicularly connected; the first subsequent section is connected to the starting section, and the second subsequent section is connected to the oil outlet channel.

[0013] The initial section is equipped with a first one-way valve so that the shock wave buffer can unidirectionally recover the high-density shock wave in the oil without backflowing into the valve core; the oil that has been released by the shock wave buffer and whose density is dispersed and stabilized passes through the first and second subsequent sections and is returned to the oil outlet channel, so that the oil shock wave carried in the oil inlet channel is eliminated in the oil outlet channel.

[0014] A first control valve is installed in the oil outlet channel. The first control valve is located in the upstream section of the oil outlet channel and is not connected to the second downstream section.

[0015] The recycling channel also includes a tail section, which is connected to the starting section; the tail section includes a first tail section and a second tail section that are perpendicularly connected; the first tail section is connected to the starting section, and the second tail section is connected to the valve core.

[0016] A second one-way valve is installed in the initial section so that the shock wave buffer can unidirectionally recover the high-density shock wave in the oil without backflowing into the valve core. The oil that has been released and stabilized by the shock wave buffer is returned to the valve core through the first and second end sections. The energy released and recovered by the shock wave buffer continues to rotate with the valve core, and after the next round of shock wave impact, it is thrown out by the rotating cup into the oil outlet channel.

[0017] A sealing structure connects the valve seat and the valve cover, and the valve seat and valve cover are connected by bolts to form the valve body structure.

[0018] The inside of the rotor cup mouth adopts a hemispherical or semi-ellipsoidal structure; when the rotor cup adopts a hemispherical structure, the inner radius of the rotor cup mouth is not less than the hydraulic diameter of the oil inlet channel; when the rotor cup adopts a semi-ellipsoidal structure, the inner minor axis of the rotor cup mouth is not less than the hydraulic diameter of the oil inlet channel.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] This application involves passing oil containing shock waves through the inlet channel to impact the rotating cup, causing the rotating cup to drive the valve core to rotate around the rotating shaft. The shock waves expand rapidly inside the rotating cup and splash out. The splashed oil enters the recovery channel through the centrifugal force of the rotating cup, and the shock wave energy of this part of the oil is absorbed by the shock wave buffer at the bottom of the recovery channel. Part of the remaining oil in the rotating cup is thrown into the outlet channel by the impact rotation and centrifugal force of the rotating cup, and part of it enters the next impact cycle with the rotation of the rotating cup.

[0021] This application includes three design schemes for the recovery channel. The first scheme includes an initial section connected to a shock wave buffer. The shock wave energy is absorbed by the shock wave buffer at the bottom of the initial section, allowing the buffered shock wave liquid to return to the rotating space of the valve core through the initial section. As the valve core rotates, the shock wave energy is thrown into the oil outlet channel, further eliminating shock wave pulses and achieving a more stable output pressure. The second scheme connects the initial section of the recovery channel to a subsequent section, which is also connected to the initial section. Upon entering the initial section, the shock wave buffer can unidirectionally recover the high-density shock wave in the oil without it flowing back into the valve core. Instead, the high-density shock wave is released through the shock wave buffer. After the oil is dispersed and stabilized, it enters the subsequent section from the initial section and is then returned to the outlet channel, thus eliminating the oil shock wave carried in the inlet channel. In the third scheme, the initial section of the recovery channel is also connected to the end section. Similar to the second scheme, the shock wave buffer can unidirectionally recover the high-density shock wave in the oil without it flowing back into the valve core. Instead, the oil, after being dispersed and stabilized by the shock wave buffer, flows from the initial section through the end section and is returned to the valve core. The energy released and recovered by the shock wave buffer continues to rotate with the valve core, undergoing the next round of shock wave impact before being thrown out by the rotor into the outlet channel. This not only eliminates the shock wave pulse but also further increases the output pressure, achieving high-pressure stable flow output. Attached Figure Description

[0033] Existing methods for calculating discrete pulse flow rates typically employ flow measurement instruments, with traditional instruments primarily including non-contact Hall sensors. Hall sensors are magnetic field sensors based on the Hall effect. The Hall effect is a type of magnetoelectric effect; the Hall voltage changes with the strength of the magnetic field—the stronger the magnetic field, the higher the voltage, and vice versa. The Hall voltage is very small, typically only a few millivolts, but it can be amplified by an amplifier in an integrated circuit to produce a strong output signal. For the Hall integrated circuit to function as a sensor, a mechanical method is needed to change the magnetic field strength. Current methods use a rotating impeller as a switch to control the magnetic flux. When the impeller blades are in the air gap between the magnet and the Hall integrated circuit, the magnetic field deviates from the integrated circuit, and the Hall voltage disappears.

[0034] With this configuration, changes in the output voltage of the Hall integrated circuit can correspond to a specific position of the impeller drive shaft. Hall effect sensors are passive sensors, requiring an external power supply to operate, a characteristic that allows them to detect low-speed operation. Utilizing this working principle, the main function of the Hall effect sensor is to identify the phase position information of the motor windings and convert it into an electrical signal. The driver obtains the rotor's position information by reading the output level signal of the Hall element. The logic switch completes the correct commutation based on the motor's rotor position information, supplying current to the corresponding winding and forming a rotating magnetic field in the air gap, causing the motor to run continuously. Because the flow rate of hydraulic fluid is comparable to the current of a motor, there is an urgent need for a device to eliminate shock waves and smooth pulsating impacts. Based on this, this application proposes a shock wave discrete rotary valve.

[0035] This application relates to a shock wave discrete rotary valve, such as Figures 1-3 As shown, it includes a valve body 1, a valve core 2, a shock wave buffer 3, and a sensor; the valve body 1 includes a valve cover and a valve seat that are symmetrically connected; the valve cover and valve seat have a support groove, a cavity, an oil inlet channel 4, a recovery channel 5, and an oil outlet channel 6 formed therein, and a bearing is installed in the support groove;

[0036] The valve core 2 includes a rotating shaft 7, a rotary disk 8, and multiple rotating cups 9 disposed in a cavity; the two ends of the rotating shaft 7 are connected to bearings in the support groove; the rotary disk 8 is fixedly connected to the middle of the rotating shaft 7 with the rotating shaft 7 as the axis, and the multiple rotating cups 9 are equally spaced on the outer periphery of the rotary disk 8; the sensor is disposed outside the valve cover and / or valve seat outside the rotating cavity of the rotating cups 9 of the valve body 1;

[0037] The center lines of the oil inlet channel 4 and the oil outlet channel 6 are collinear and tangent to the movement trajectory of the center of the rotating cup 9; the opening direction of the rotating cup 9 at the tangent point is towards the oil inlet channel 4, and a recovery channel 5 is opened at the tangent point along the radial direction of the valve core 2, and a shock wave buffer 3 is set at the bottom of the recovery channel 5.

[0038] The oil containing shock waves impacts the rotating cup 9 through the oil inlet channel 4, causing the rotating cup 9 to drive the valve core 2 to rotate around the rotating shaft 7. The shock waves expand rapidly inside the rotating cup 9 and splash out. The splashed oil enters the recovery channel 5 through the centrifugal force of the rotating cup 9, and the shock wave energy of this part of the oil is absorbed by the shock wave buffer 3 at the bottom of the recovery channel 5. Part of the remaining oil in the rotating cup 9 is thrown into the oil outlet channel 6 by the impact rotation and centrifugal force of the rotating cup 9, and part of it enters the next impact cycle with the rotation of the rotating cup 9.

[0039] Specifically, a Hall sensor is preferred. The number of rotations and the time taken by the sensor are used to determine the flow rate of the oil entering the oil inlet channel 4 of the valve core 2. The valve core 2 is equipped with a Hall element and other measuring devices to measure the rotation speed or angle of the valve core 2. After tabulating the relationship between rotation speed and flow rate, the relationship between rotation speed, duration and flow rate is calculated by looking up the table using a computer.

[0040] The shock wave discrete rotary valve of this application has the following several implementation methods regarding the structure of the recovery channel 5:

[0041] Implementation Method 1:

[0042] The recovery channel 5 has a starting section 10 connected to the shock wave buffer 3. The rotation axis of the starting section 10 is perpendicular to the rotation axis of the oil inlet channel 4 or the angle between them is no more than 120°. This allows the rotating cup 9 to rotate after being impacted by the shock wave liquid and be thrown into the starting section 10 of the recovery channel 5. Alternatively, when the rotating cup 9 rotates to a range where the angle between it and the rotation axis of the oil inlet channel 4 is 120°, the shock wave liquid reflected by the rotating cup 9 can still be thrown into or splashed out to the starting section 10 of the recovery channel 5. This allows the shock wave energy of the shock wave liquid to be absorbed by the shock wave buffer 3 at the bottom of the starting section 10 of the recovery channel 5. After being buffered and delayed, the shock wave liquid can return to the rotating cup 9 through the starting section 10 of the recovery channel 5 and flow into the oil outlet channel 6 as the rotating cup 9 rotates.

[0043] Specifically, the recovery channel 5 includes an initial section 10 connected to the shock wave buffer 3; both the initial section 10 and the oil inlet channel 4 of the recovery channel 5 are designed to rotate, and the rotation axes of the initial section 10 and the oil inlet channel 4 are on the split surface between the valve cover and the valve seat of the valve body 1. The rotation axis of the initial section 10 of the recovery channel 5 is perpendicular to the rotation axis of the oil inlet channel 4 or the included angle is no greater than 120°, so that when the rotating cup 9 on the valve core 2 is impacted by the shock wave to a range of 120° with the rotation axis of the oil inlet channel 4, the rotating cup 9, whose size is not less than the hydraulic diameter of the oil inlet channel 4, can still throw or splash the shock wave in the cup into or out of the initial section 10 of the recovery channel 5, and its shock wave energy is absorbed by the shock wave buffer 3 at the bottom of the initial section 10 of the recovery channel 5. Therefore, through the design of the recovery channel 5 in the first implementation method, the shock wave liquid after buffering and hysteresis can be returned to the rotating space of the rotating cup 9 of the valve core 2 through the starting section 10 of the recovery channel 5, and thrown into the oil outlet channel 6 as the rotating cup 9 rotates.

[0044] Furthermore, the rotation space of the rotating cup 9 and the rotary disk 8 is enveloped by the cavity, and the envelopment gap is no more than 1mm, so as to ensure that the excess oil after the shock wave is expanded by the spherical rotating cup 9 is absorbed by the recovery channel 5 opened in the radial direction of the valve core 2. The remaining oil is centrifugally thrown into the oil outlet channel 6 with the rotating cup 9, and part of it enters the next impact cycle with the rotation of the rotating cup 9.

[0045] Implementation Method Two:

[0046] The recovery channel 5 also includes a subsequent section 11, which is connected to the starting section 10. The subsequent section 11 includes a first subsequent section 111 and a second subsequent section 112 that are perpendicularly connected. The first subsequent section 111 is connected to the starting section 10, and the second subsequent section 112 is connected to the oil outlet channel. A first one-way valve 14 is provided in the starting section 10 so that the shock wave buffer 3 can recover the high-density shock wave in the oil in one direction without backflowing into the valve core 2. The oil that has been released by the shock wave buffer 3 and whose density is dispersed and stabilized passes through the first subsequent section 111 and the second subsequent section 112 in sequence and is returned to the oil outlet channel 6, so that the oil shock wave carried in the oil inlet channel 4 is eliminated in the oil outlet channel 6.

[0047] If the recovery channel 5 has other subsequent sections 11 besides the initial section 10, and the subsequent sections 11 are connected to the oil outlet channel 6, then a first one-way valve 14 is set between the initial section 10 of the recovery channel 5 and the shock wave buffer 3, so that the shock wave buffer 3 can unidirectionally recover the high-density shock wave in the oil without backflowing into the valve core 2; the subsequent section 11 of the recovery channel 5 will return the oil that has been released by the shock wave buffer 3 and whose density has been dispersed and stabilized to the oil outlet channel 6, so that the oil shock wave carried in the oil inlet channel 4 is eliminated in the oil outlet channel 6.

[0048] Furthermore, a first control valve 12 is provided in the oil outlet channel 6. The first control valve 12 is located in the upstream section of the oil outlet channel 6 and is not connected to the second subsequent section 112.

[0049] Implementation Method 3:

[0050] The recovery channel 5 also includes a tail section 13, which is connected to the starting section 10. The tail section 13 includes a first tail section 131 and a second tail section 132 that are perpendicularly connected. The first tail section 131 is connected to the starting section 10, and the second tail section 132 is connected to the valve core 2. A second one-way valve 15 is provided in the starting section 10 so that the shock wave buffer 3 can recover the high-density shock wave in the oil in one direction without backflowing into the valve core 2. The oil that has been released and dispersed by the shock wave buffer 3 is returned to the valve core 2 through the first tail section 131 and the second tail section 132. The energy released and recovered by the shock wave buffer 3 continues to rotate with the valve core 2 and is thrown out by the rotating cup 9 into the oil outlet channel 6 after the next round of shock wave impact.

[0051] If the subsequent section 11 of the recovery channel 5 is connected to the valve core 2, a second one-way valve 15 is set between the initial section 10 of the recovery channel 5 and the shock wave buffer 3, so that the shock wave buffer 3 can unidirectionally recover the high-density shock wave in the oil without backflowing into the valve core 2; the subsequent section 11 of the recovery channel 5 receives the oil that has been released by the shock wave buffer 3 and has been dispersed and stabilized, and returns it to the valve core 2 on the opposite side of the initial section 10 of the recovery channel 5, so that the energy released and recovered by the shock wave buffer 3 continues to rotate with the valve core 2 in the rotating cup 9 on the opposite side of the recovery channel 5, and then is thrown out by the rotating cup 9 into the oil outlet channel 6 after being impacted by the next round of shock waves, so that the oil in the oil outlet channel 6 is more stable.

[0052] A second control valve 16 is provided in the oil outlet channel 6. The second control valve 16 is preferably a one-way valve, which allows the oil to be output from the oil outlet channel 6 to the outside.

[0053] In a preferred embodiment, since the valve seat and valve cover are symmetrically connected to form the valve body 1, a sealing structure is connected between the valve seat and the valve cover. The valve seat and valve cover are connected by bolts to form the valve body 1 structure, thereby enhancing the sealing strength of the valve body 1.

[0054] As a preferred embodiment, the inside of the cup mouth of the rotating cup 9 adopts a hemispherical structure or a semi-ellipsoidal structure; when the rotating cup 9 adopts a hemispherical structure, the inner radius of the cup mouth of the rotating cup 9 is not less than the hydraulic diameter of the oil inlet channel 4; when the rotating cup 9 adopts a semi-ellipsoidal structure, the inner minor axis of the cup mouth of the rotating cup 9 is not less than the hydraulic diameter of the oil inlet channel 4.

[0055] The hydraulic diameter is defined as the characteristic length that is four times the cross-sectional area of ​​the flow path to the wetted perimeter, and is used for calculating the Reynolds number in non-circular pipe flow.

[0056] When the rotating cup 9 adopts a hemispherical structure, the inner radius of the cup opening of the rotating cup 9 is not less than the hydraulic diameter of the oil inlet channel 4. Alternatively, when the rotating cup 9 adopts a semi-ellipsoidal structure, the inner minor axis of the cup opening of the rotating cup 9 is not less than the hydraulic diameter of the oil inlet channel 4, thereby enabling the oil in the cup opening of the rotating cup 9 to be thrown out into the oil inlet channel 4.

9. A shock wave dispersing rotary valve as claimed in claim 1, characterized in that A sealing structure is connected between the valve seat and the valve cover, and the valve seat and the valve cover are connected by bolts to form a valve body structure.

10. A shock wave dispersing rotary valve as claimed in claim 1, characterized in that The cup opening of the rotating cup is internally provided with a hemispherical structure or a semi-ellipsoidal structure; when the rotating cup is provided with a hemispherical structure, the internal radius of the cup opening of the rotating cup is not less than the hydraulic diameter of the oil inlet flow channel; when the rotating cup is provided with a semi-ellipsoidal structure, the short axis of the cup opening of the rotating cup is not less than the hydraulic diameter of the oil inlet flow channel.
