[0002] A compensation valve is a valve that can automatically adjust its opening according to changes in fluid pressure, flow and temperature. By adjusting the opening of the valve, the pressure and flow in the system are compensated, thereby ensuring the safety and stability of the system operation. Compensation valves are widely used in the field of vehicle shock absorption. Compensation valves are usually installed inside the vehicle shock absorber. When the vehicle is driving on a bumpy road, the compensation valve can respond quickly and adjust the damping force and buffer the impact force to achieve the purpose of vehicle shock absorption. This allows the vehicle to adapt to different road conditions and provide passengers with a comfortable ride experience. The compensation valve includes a valve plate unit and a valve column unit. During the installation of the compensation valve, the valve plate unit needs to be sleeved on the valve column unit.

[0043] The compensation valve 01 is a valve that can automatically adjust its opening by sensing pressure changes. It is widely used in vehicle fuel systems, hydraulic systems, etc. It mainly includes a valve plate unit 11 and a valve column unit 12. When the pressure changes, the pressure acting on the valve plate unit 11 will also change accordingly. This part of the pressure is converted into a mechanical action, changing the opening size of the valve, thereby controlling the flow and pressure of the medium. During the assembly process of the compensation valve 01, the valve plate unit 11 needs to be sleeved on the valve column unit 12. However, the assembly of the compensation valve 01 is still generally carried out by manual installation, which makes the assembly efficiency of the compensation valve 01 low, which is not conducive to the mass production of the compensation valve 01. The present embodiment provides a compensation valve assembly system, such as Figure 1As shown, the compensation valve assembly system may include a compensation valve 01, a second positioning assembly 03 and a pressing assembly 04. The compensation valve 01 may include a valve plate unit 11 and a valve column unit 12. The valve plate unit 11 may play a role in regulating flow during the operation of the compensation valve 01. Figure 7 As shown, the valve plate unit 11 may include a ring plate 111 and three spring plates 112. One end of the spring plate 112 may be fixedly connected to the inner circumferential surface of the ring plate 111, and the other end may extend toward the direction close to the central axis of the ring plate 111. The three spring plates 112 may be evenly spaced along the circumference of the ring plate 111. The valve column unit 12 may include a first column tube 121, a second column tube 122, and a third column tube 123. The first column tube 121, the second column tube 122, and the third column tube 123 are fixedly connected in sequence. 3 / 4T1<D2<T1<D1<min(D3,T2),D1 is the outer diameter of the first column tube 121, D2 is the outer diameter of the second column tube 122, D3 is the outer diameter of the third column tube 123, T1 is the minimum inscribed circle diameter formed by the contours of the three spring plates 112, and T2 is the maximum circumscribed circle diameter formed by the contours of the three spring plates 112. The minimum inscribed circle diameter formed by the contours of the three spring pieces 112 is slightly larger than the outer diameter of the second column tube 122, so that the valve unit 11 can move along the central axis of the second column tube 122 after being sleeved on the second column tube 122, thereby playing a role in regulating the flow. The minimum inscribed circle diameter formed by the contours of the three spring pieces 112 is smaller than the outer diameter of the first column tube 121, thereby preventing the valve unit 11 from falling off from the valve column unit 12.

[0044] The second positioning assembly 03 may include a second seat unit 31 and a lifting unit 33. The second seat unit 31 may include a third tilting platform 311 and a third guide hole 313. The third guide hole 313 may penetrate the positioning surface of the third tilting platform 311, so that the lifting unit 33 can extend from the third guide hole 313. During the assembly of the compensation valve, the spring 112 is lifted by the lifting unit 33. The minimum angle β between the setting plane and the positioning surface of the third tilting platform 311 is set as a setting range value. The setting plane may be a horizontal plane. The lifting unit 33 may include a lift rod 331 and a third driving part 332. The third driving part 332 may drive the lift rod 331 to slide in the third guide hole 313.

[0045] The pressing assembly 04 may include a pressing rod 41 and a fourth driving unit 42. The fourth driving unit 42 may drive the pressing rod 41 to move in a direction parallel to the axis of the third guide hole 313.

[0046] The compensation valve assembly system may include a first positioning state and a pressing state. The first positioning state may include the ring sheet 111 abutting against the positioning surface of the third tilting platform 311, so that the valve sheet unit 11 can be tilted to facilitate the assembly of the valve sheet unit 11. A spring sheet 112 is close to the third guide hole 313 and is arranged corresponding to the third guide hole 313, so that the push rod 331 can extend from the third guide hole 313, so that the spring sheet 112 is lifted by the push rod 331. Part of the first column tube 121 passes through the minimum inscribed circle formed by the contours of the three spring sheets 112, and the two spring sheets 112 away from the third guide hole 313 can be located in the area between the first column tube 121 and the third column tube 123, and the spring sheet 112 close to the third guide hole 313 is located on the side of the first column tube 121 away from the third column tube 123. The pressed state may include the push rod 331 abutting against the valve plate unit 11 to deform a spring sheet 112 near the third guide hole 313, and the push rod 331 lifts the spring sheet 112 on the side of the first column tube 121 away from the third column tube 123, so that the spring sheet 112 near the third guide hole 313 can move from one side of the first column tube 121 to the other side of the first column tube 121. Through the compensation valve assembly system, the compensation valve 01 can be assembled through the compensation valve assembly system, reducing manual intervention, greatly improving the assembly efficiency of the compensation valve 01, and facilitating mass production of the compensation valve 01.

[0047] In this embodiment, if Figure 5 As shown, the third tilting platform 311 may include a first tilting portion 3111 and a second tilting portion 3112. The first tilting portion 3111 and the second tilting portion 3112 may be fixedly connected along a set direction. The third guide hole 313 may penetrate the positioning surface of the second tilting portion 3112. The height of the positioning surface of the first tilting portion 3111 may gradually decrease along the set direction. The height of the positioning surface of the second tilting portion 3112 may gradually decrease along the set direction. The set direction may be a horizontal rightward direction, and the set plane may be a horizontal plane. Figure 6 As shown, the minimum angle β between the setting plane and the positioning surface of the second inclined portion 3112 can be greater than the minimum angle γ between the setting plane and the positioning surface of the first inclined portion 3111. This allows a certain gap to exist between the first inclined portion 3111 and the valve plate unit 11. During the press-fitting process, when a spring sheet 112 of the valve plate unit 11 close to the third guide hole 313 is lifted up, one end of the valve plate unit 11 close to the first inclined portion 3111 can be offset toward the gap to abut against the first inclined portion 3111. The overall deflection of the valve plate unit 11 can reduce the amount of local deformation when the spring sheet 112 close to the third guide hole 313 is lifted up by the push rod 331 during the press-fitting process, thereby preventing the valve plate unit 11 from deforming and affecting the performance of the compensation valve 01.

[0048] In this embodiment, β=α*K; wherein the calculation formula of α is:

[0049] .

[0050] h is the axial dimension close to the first column tube 121; K is the inclination coefficient, K>1, preferably, K is 1.05~1.2. The minimum angle β between the setting plane and the positioning surface of the second inclined portion 3112 is determined by this formula, so that the valve column unit 12 can enter the valve plate unit 11, and the degree of upward bending of the ring plate 111 during the assembly process can be reduced, so as to prevent the valve plate unit 11 from deforming, thereby affecting the performance of the compensation valve 01.

[0051] In this embodiment, the positioning surface area of ​​the first inclined portion 3111 can be smaller than the positioning surface area of ​​the second inclined portion 3112. The larger positioning surface area of ​​the second inclined portion 3112 makes the abutment surface between the valve plate unit 11 and the second inclined portion 3112 larger before pressing, and no additional equipment is required to prevent the relative movement between the valve plate unit 11 and the second inclined portion 3112 before pressing, thereby ensuring the accuracy of the pressing position of the valve plate unit 11.

[0052] In this embodiment, the valve plate unit 11 may further include an elastic unit 13. The outer diameter of the elastic unit 13 may gradually increase along the height direction of the elastic unit 13. D4<D3. D4<D1. D5≥T1. D4 is the minimum inner diameter of the elastic unit 13. D5 is the maximum outer diameter of the elastic unit 13. Prevent the elastic unit 13 from falling off the valve column unit 12. When the elastic unit 13 is subjected to external force, the height dimension of the elastic unit 13 may change. By setting the elastic unit 13, the distance between the valve plate unit 11 and the first column tube 121 may change with the change of pressure, so as to facilitate the compensation valve 01 to control the flow and pressure of the medium. At the same time, the design of the elastic unit 13 can prevent the third column tube 123 from being too close to the valve plate unit 11, thereby affecting the normal use of the compensation valve 01.

[0053] In this embodiment, the compensation valve assembly system may further include a first positioning component 02. The first positioning component 02 may include a first seat unit 21 and a connection unit 22. The first seat unit 21 may include a seat platform 211 and a first avoidance groove 213. One end of the connection unit 22 may be fixedly connected to one end of the third tilting platform 311 close to the third guide hole 313, and the other end may be detachably connected to the seat platform 211. The first avoidance groove 213 may be recessed from the positioning surface of the seat platform 211 along the axis of the third guide hole 313 toward the other side. In other embodiments, such as Figure 4As shown, the connection unit 22 may include two first inclined platforms 221 and a second inclined platform 222. The two first inclined platforms 221 may be arranged at intervals on both sides of the first avoidance groove 213 along the width direction of the seat 211. One end of the two first inclined platforms 221 may be fixedly connected to the seat, and the other end may extend obliquely toward the third inclined platform 311. One end of the second inclined platform 222 may be fixedly connected to one end of the two first inclined platforms 221 close to the third inclined platform 311, and the other end may be fixedly connected to one end of the third inclined platform 311 close to the third guide hole 313. The minimum angle between the top surface of the first inclined portion 3111 and the positioning surface of the second inclined platform 222 may be smaller than the minimum angle between the top surface of the second inclined portion 3112 and the second inclined platform 222 and the third inclined platform 311. The two-stage inclined platform design gradually reduces the difference in the degree of inclination between the valve column unit 12 and the third inclined platform 311 during the movement of the valve column unit 12, and reduces the vibration and noise impact of the valve column unit 12 during the assembly process.

[0054] The compensation valve assembly system may also include a second positioning state and a third positioning state. The second positioning state may include the elastic unit 13 abutting against the positioning surface of the seat 211, and the elastic unit 13 may abut against one end of the first column tube 121 away from the third column tube 123, so as to facilitate the subsequent assembly of the elastic component. The third positioning state may include the pressure rod 41 abutting against the valve column unit 12 so that at least part of the valve column unit 12 is located in the space surrounded by the first avoidance groove 213, so that the pressure rod 41 can drive the valve column unit 12 and the elastic unit 13 to move. Part of the elastic unit 13 can be sleeved on the outer peripheral side of the second column tube 122, so that the valve column unit 12 can drive the elastic unit 13 to move. Part of the elastic unit 13 can abut against the positioning surface of the seat 211, so that when the elastic unit 13 is under pressure, it can provide the valve column assembly with elastic force in the upward direction of the seat 211, thereby reducing the friction between the valve column unit 12 and the seat 211 when it moves, and preventing the valve column unit 12 from wearing when it moves. When the valve column unit 12 and the elastic unit 13 are placed on the seat 211, since the minimum inner diameter of the elastic unit 13 is smaller than the outer diameter of the first column tube 121, the elastic unit 13 cannot directly abut against the second column tube 122, and the elastic unit 13 can be pressed down by the pressure rod 41 to make it abut against the second column tube 122.

[0055] In this embodiment, the first seat unit 21 may further include a first guide hole 212. The first guide hole 212 may penetrate the positioning surface of the seat platform 211, so that the first positioning column 231 may extend from the first guide hole 212 to fix the position of the valve column unit 12. The first guide hole 212 may be connected to the first avoidance groove 213. In other embodiments, the bottom of the first avoidance groove 213 may be higher than the right side of the third inclined platform 311, so that the pressure rod 41 can directly move along the direction of the first avoidance groove 213 after pressing down the elastic unit 13, without moving up and down, thereby reducing the movement steps of the pressure rod 41 during the assembly of the compensation valve and improving the assembly efficiency of the compensation valve 01. The pressing assembly 04 may further include a fifth driving part 43, which may drive the pressure rod 41 to move along the direction of the first avoidance groove 213.

[0056] The first positioning assembly 02 may further include a first positioning unit 23. The first positioning unit 23 may include a first positioning column 231 and a first driving portion 232. The first positioning column 231 is drivingly connected to the first driving portion 232. The first guide hole 212 sleeve may be provided on the outer peripheral side of the first positioning column 231. The first driving portion 232 may be drivingly connected to the first positioning column 231 to drive the first positioning column 231 to move along the axis of the first guide hole 212, so that when the first positioning column 231 rises, the first positioning column 231 may play a certain positioning role on the valve column unit 12.

[0057] The second positioning state may also include that part of the first positioning column 231 is located on the side of the seat 211 away from the first guide hole 212, the inner circumference of the valve column unit 12 may abut against the outer circumference of the first positioning column 231, and the inner circumference of the elastic unit 13 may abut against the outer circumference of the first positioning column 231, and the auxiliary valve column unit 12 plays a certain positioning role on the elastic unit 13, which is convenient for the pressing between the elastic unit 13 and the valve column unit 12. The third positioning state may also include that the first positioning column 231 and the space surrounded by the first avoidance groove 213 are arranged at intervals, the first positioning column 231 and the valve column unit 12 are arranged at intervals, and the first positioning column 231 and the elastic unit 13 are arranged at intervals, so that the valve column unit 12 and the elastic unit 13 can move relative to the first positioning column 231, which is convenient for the valve column unit 12 and the elastic unit 13 to move in the direction close to the second positioning assembly 03, and complete the subsequent assembly of the compensation valve 01.

[0058] In this embodiment, the second seat unit 31 may further include a second guide hole 312. The second guide hole 312 may penetrate the positioning surface of the third tilting platform 311. Figure 2 As shown, the second guide hole 312 may be spaced apart from the third guide hole 313 .

[0059] The second positioning assembly 03 also includes a second positioning unit 32. The second positioning unit 32 may include a second positioning column 321 and a second driving portion 322. The second guide hole 312 may be sleeved on the outer peripheral side of the second positioning column 321. The second positioning column 321 may be drivingly connected to the second driving portion 322 to drive the second positioning column 321 to move along the axis of the second guide hole 312. Thus, when the second positioning column 321 rises, the second positioning column 321 may play a certain positioning role on the valve plate unit 11.

[0060] The first positioning state may also include that the center of the ring sheet 111 coincides with the central axis of the second guide hole 312, part of the second positioning column 321 may be located on the side of the third tilting platform 311 away from the second guide hole 312, and the valve unit 11 may be sleeved on the outer peripheral side of the second positioning column 321, so that the valve unit 11 can adjust the position of the spring sheet 112 through the second positioning column 321 to ensure that the position of the spring sheet 112 conforms to the first installation state, which is convenient for the subsequent pressing of the valve unit 11. Figure 3 As shown, the pressed state may further include that the second positioning column 321 is spaced apart from the valve sheet unit 11 , so that the valve sheet unit 11 can move relative to the second positioning column 321 , thereby facilitating the pressing of the valve sheet unit 11 .

[0061] This embodiment discloses a compensation valve assembly method, which can be applied to the compensation valve assembly system of any of the above embodiments, such as Figure 8 As shown, the compensation valve assembly method may include steps S11 to S14, and each step is described in detail as follows:

[0062] In step S11, based on the completion of the positioning of the compensation valve 01, the pressure rod 41 can drive the valve column unit 12 to move toward the valve sheet unit 11. The completion of the positioning can include the valve sheet unit 11 abutting against the positioning surface of the third tilting platform 311. The two springs 112 away from the third guide hole 313 can be located in the area between the first column tube 121 and the third column tube 123. In step S12, based on the movement of the valve column unit 12 to the compensation valve assembly system in the first positioning state, the pressure rod 41 can stop moving.

[0063] In step S13 , based on the stop of the pressing rod 41 , the push rod 331 can move toward the valve plate unit 11 by a first set distance.

[0064] In step S14, based on the push rod 331 moving a first set distance toward the valve sheet unit 11, the push rod 331 can stop moving, and the spring piece 112 on the side of the first column tube 121 away from the third column tube 123 is lifted by the push rod 331, so that a spring piece 112 close to the third guide hole 313 can be moved from one side of the first column tube 121 to the other side of the first column tube 121. The compensation valve assembly system can be used to assemble the compensation valve 01, which reduces manual intervention, greatly improves the assembly efficiency of the compensation valve 01, and is conducive to the mass production of the compensation valve 01.

[0065] In this embodiment, the positioning in step S11 can be completed by abutting the positioning surface of the second inclined portion 3112 of the third inclined platform 311 by part of the valve plate unit 11, and a spacing between the first inclined portion 3111 of the third inclined platform 311. During the press-fitting process, when a spring sheet 112 of the valve plate unit 11 close to the third guide hole 313 is lifted up, one end of the valve plate unit 11 close to the first inclined portion 3111 can be offset to the gap to abut against the first inclined portion 3111. The overall deflection of the valve plate unit 11 can reduce the local deformation of the spring sheet 112 close to the third guide hole 313 when it is lifted up by the push rod 331 during the press-fitting process, thereby preventing the valve plate unit 11 from deforming and affecting the performance of the compensation valve 01. The third inclined platform 311 can include a first inclined portion 3111 and a second inclined portion 3112. The first inclined portion 3111 and the second inclined portion 3112 can be fixedly connected along a set direction. The third guide hole 313 can penetrate the positioning surface of the first inclined portion 3111 and the positioning surface of the second inclined portion 3112, so that the lifting unit 33 can be extended from the third guide hole 313. During the assembly of the compensation valve, the elastic sheet 112 is lifted by the lifting unit 33. The positioning surface area of ​​the first inclined portion 3111 is smaller than the positioning surface area of ​​the second inclined portion 3112. The larger positioning surface area of ​​the second inclined portion 3112 makes the contact surface between the valve plate unit 11 and the second inclined portion 3112 larger before pressing. No additional equipment is required to prevent the relative movement of the valve plate unit 11 and the second inclined portion 3112 before pressing, thereby ensuring the accuracy of the pressing position of the valve plate unit 11. The minimum angle β between the setting plane and the positioning surface of the second inclined portion 3112 can be greater than the minimum angle γ between the setting plane and the positioning surface of the first inclined portion 3111, so that there is a certain gap between the first inclined portion 3111 and the valve plate unit 11. During the press-fitting process, when a spring piece 112 of the valve plate unit 11 close to the third guide hole 313 is lifted up, one end of the valve plate unit 11 close to the first inclined portion 3111 can be offset toward the gap to abut against the first inclined portion 3111. The overall deflection of the valve plate unit 11 can reduce the local deformation of the spring piece 112 close to the third guide hole 313 when it is lifted up by the push rod 331 during the press-fitting process, thereby preventing the valve plate unit 11 from deforming, which in turn affects the performance of the compensation valve 01.
