Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic valves, and in particular to a multifunctional hydraulic valve assembly. Background Art

[0002] ‌Hydraulic valves control the pressure, flow and direction in hydraulic systems by regulating the passage of fluids. Hydraulic valves are mainly composed of valve cores, valve bodies, control elements and springs. When the hydraulic valve is in a closed state, the valve core will fit tightly against the valve seat to prevent the passage of fluid. When it needs to be opened, the control element applies force to move the valve core, thereby opening the passage in the valve body and allowing the pressurized oil to flow from the inlet to the outlet. The position of the valve core determines the pressure and flow of the fluid. The hydraulic valve can also change the position of the valve core according to the signal of the control element, thereby controlling the direction and pressure of the hydraulic system.

[0003] Hydraulic valves play a vital role in hydraulic systems. They meet the needs of actuators by controlling the direction, pressure and flow of liquids. There are many types of hydraulic valves, including directional control valves, pressure control valves and flow control valves. Directional control valves are further divided into one-way valves and reversing valves. However, existing reversing valves still have the following defects when used: The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is usually composed of a valve body, a valve core, a sealing component, a drive mechanism, etc. There are multiple recessed grooves on the valve body, which are connected to the outside through channels. There are multiple steps on the valve core. By changing the connection relationship between the steps on the valve core and the recessed grooves on the valve body, oil circuit switching can be achieved. The main function of the reversing valve is to control the flow direction of the fluid, but it does not have the ability to regulate the flow and cannot accurately control the flow through the valve, which may cause system pressure fluctuations and unstable flow, thereby affecting the stability and performance of the entire hydraulic system; moreover, in situations where precise flow control is required, if the reversing valve cannot regulate the flow, the system may need to add additional throttling devices or adjust the output pressure of the pump to achieve the required flow control, which not only increases the complexity of the system but also may lead to increased energy consumption; in addition, in some complex hydraulic systems, it may be necessary to control the direction and flow of the fluid at the same time. If the reversing valve does not have the flow regulation function, then additional flow control elements are required to achieve this function, thereby increasing the cost of using the system; in addition, for different workloads and working conditions, different flow rates may be required to meet the needs of the system. If the reversing valve cannot regulate the flow, then the system may not be able to flexibly adapt to these changes, thereby affecting its performance and efficiency. Summary of the invention

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] Example 1, reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a multifunctional hydraulic valve assembly, including a housing 1, a liquid inlet pipe 11 installed on the housing 1, a top cover 12 installed on the top of the housing 1, and a plurality of liquid outlet pipes 13 installed on the housing 1 and distributed symmetrically in the center, and also includes a control unit installed on the housing 1; the control unit includes an opening and closing control component installed on the housing 1, a first locking component installed on the housing 1, and a second locking component installed on the top of the housing 1, the opening and closing control component includes an opening and closing control component 2 installed on the liquid outlet pipe 13, a telescopic component 3 installed on the opening and closing control component 2, and a pushing component 4 installed on the housing 1; the opening and closing control component 2 includes a tapered groove 22 opened on the inner side of the liquid outlet pipe 13, a threaded rod 23 rotatably connected to the liquid outlet pipe 13, a sealing plate 21 threadedly sleeved on the outer side of the threaded rod 23, the sealing plate 21 is slidably connected to the inner side of the tapered groove 22, a limit rod 24 fixedly connected to the inner side of the tapered groove 22, and the sealing plate 21 is slidably connected to the outer side of the limit rod 24.

[0021] Specifically, when in use, liquid can enter the shell 1 from the liquid inlet pipe 11, and the liquid in the shell 1 can flow out from the liquid outlet pipe 13 through the liquid outlet pipe 13, and there are multiple liquid outlet pipes 13 distributed symmetrically around the center, so that the liquid in the shell 1 can flow out from the liquid outlet pipes 13 at different positions, which plays a role in reversing the flow of the liquid. The opening and closing of the liquid outlet pipe 13 can be controlled by the opening and closing control component, and the flow rate of the liquid outflowing from the liquid outlet pipe 13 can also be controlled. The opening and closing control component 2 allows the liquid outlet pipe 13 to discharge or prevent the liquid from being discharged, and can also control the flow rate of the outflowing liquid, so that the device can not only control the flow direction of the liquid, but also control the flow rate of the liquid, thereby increasing the The versatility of the device reduces the complexity of the system, reduces energy consumption, and improves the efficiency of the device. By pushing the component 4, the telescopic component 3 is driven to rotate, the opening and closing control component 2 is driven to rotate, and then the threaded rod 23 is driven to rotate. Under the action of the limit rod 24, the sealing plate 21 is driven to slide on the outside of the threaded rod 23, so that the sealing plate 21 slides on the inside of the conical groove 22, and the conical groove 22 is opened or closed, so that the liquid outlet pipe 13 is opened or closed, and then the opening and closing of the liquid outlet pipe 13 can be controlled. The sealing plate 21 slides on the inside of the conical groove 22, so that the distance between the side of the sealing plate 21 and the inner wall of the conical groove 22 becomes farther or closer, so that the cross-sectional area of ​​the liquid outlet of the liquid outlet pipe 13 gradually increases or decreases, so that the flow rate of the liquid outlet pipe 13 can be controlled, and the function of the hydraulic valve is increased.

[0022] Reference Figure 5 The telescopic assembly 3 includes an active cavity 31 opened on the threaded rod 23 , an inner rod 32 limitedly slidably connected in the active cavity 31 , and a first spring 33 fixedly connected between the inner rod 32 and the inner wall of the active cavity 31 .

[0023] Specifically, in order to realize the opening and closing control of multiple liquid outlet pipes 13, the threaded rods 23 are located at different positions on the sealing plate 21 and are arranged in sequence from high to low. When one of the liquid outlet pipes 13 is controlled, the other inner rods 32 are pushed to move into the active cavity 31, squeezing the first spring 33. When the inner rod 32 is no longer pushed, under the action of the first spring 33, the inner rod 32 moves to the outside of the active cavity 31 and resets.

[0024] Reference Figure 6 The pushing assembly 4 includes a bevel gear 42 fixedly connected to the inner rod 32, a rotating shaft 43 movably connected to the housing 1, the rotating shaft 43 is movably connected to the top cover 12, and an end face gear 41 fixedly sleeved on the outer side of the rotating shaft 43, and the bevel gear 42 is meshedly connected with the end face gear 41.

[0025] Specifically, rotating the rotating shaft 43 drives the end face gear 41 to rotate, drives the bevel gear 42 to rotate, drives the inner rod 32 to rotate, and the inner rod 32 is connected to the movable chamber 31 in a limited sliding connection, thereby driving the threaded rod 23 to rotate, and one of the liquid outlet pipes 13 is opened and closed and the flow rate is controlled. When it is necessary to open and close the other liquid outlet pipe 13 and control the flow rate, the rotating shaft 43 is pushed upward or downward to move, thereby driving the end face gear 41 to move upward or downward, so that the end face gear 41 slides on the bevel gear 42, and under the action of the telescopic component 3, the bevel gear 42 moves to one side of the threaded rod 23. After the end face gear 41 leaves the bevel gear 42, under the action of the first spring 33, the bevel gear 42 moves away from the threaded rod 23 and resets. When the end face gear 41 moves, it can re-engage with the other bevel gear 42. When the end face gear 41 rotates, it drives the bevel gear 42 to rotate, and then the opening and closing and flow rate of multiple liquid outlet pipes 13 can be controlled.

[0026] Example 2, reference Figure 7 and Figure 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the first locking component includes a first locking assembly 5 installed at the bottom of the rotating shaft 43, a moving assembly 6 installed on the first locking assembly 5, and a reset assembly 7 installed on the rotating shaft 43; the first locking assembly 5 includes a circular plate 51 rotatably connected to the bottom of the rotating shaft 43, a slider 52 fixedly connected to the circular plate 51, a slide groove 56 provided on the inner side of the housing 1, the slider 52 is slidably connected to the inner side of the slide groove 56, a plurality of locking grooves 57 equidistantly distributed on the inner side of the slide groove 56, a locking cavity 54 provided on the circular plate 51, a locking rod 53 limitedly slidably connected to the inner side of the locking cavity 54, an end of the locking rod 53 away from the locking cavity 54 passes through the slider 52 and is plugged into the inner side of the locking groove 57, and a second spring 55 fixedly connected between the locking rod 53 and the inner wall of the locking cavity 54.

[0027] Specifically, under the action of the slider 52 and the slide groove 56, the circular plate 51 can move in the shell 1, driving the rotating shaft 43 to move up and down. Under the action of the second spring 55, the locking rod 53 is plugged into the inner side of the locking groove 57, limiting the slider 52, and limiting the circular plate 51 and the rotating shaft 43, so that when the rotating shaft 43 rotates, the rotating shaft 43 will not move up and down. When the locking rod 53 moves into the locking cavity 54, the locking rod 53 is separated from the inner side of the locking groove 57, so that the slider 52 can slide up and down inside the slide groove 56, so that the circular plate 51 and the rotating shaft 43 can move up and down.

[0028] Reference Figure 7The moving assembly 6 includes a connecting rod 61 fixedly connected to the locking rod 53, one end of the connecting rod 61 away from the locking rod 53 passes through the locking cavity 54 and extends to the inner side of the circular plate 51, a semi-conical block 62 fixedly connected to the connecting rod 61, a pressure rod 64 limitedly slidably connected to the rotating shaft 43, a sliding groove 63 opened at the bottom of the pressure rod 64, and the semi-conical block 62 is slidably connected to the inner side of the sliding groove 63.

[0029] Specifically, in the initial state, the locking rod 53 is plugged into the inner side of the locking groove 57, and the pressing rod 64 is pressed, so that the pressing rod 64 moves downward on the inner side of the rotating shaft 43, so that the sliding groove 63 approaches the semi-conical block 62. When the pressing rod 64 is further pressed downward, the semi-conical block 62 slides on the inner side of the sliding groove 63. Under the action of the sliding groove 63, the semi-conical block 62 moves toward the mid-vertical line of the rotating shaft 43, driving the connecting rod 61 to move, driving the locking rod 53 to move, compressing the second spring 55, so that the locking rod 53 is separated from the inner side of the locking groove 57. At this time, the upper and lower Move the rotating shaft 43 to adjust the position of the end face gear 41. After the position of the end face gear 41 is adjusted, under the action of the reset assembly 7, the pressure rod 64 moves upward and resets, so that the sliding groove 63 is separated from the semi-conical block 62. Under the action of the second spring 55, the locking rod 53 moves to the outside of the locking cavity 54, so that the locking rod 53 and the inner side of the locking groove 57 are re-inserted, and then the rotating shaft 43 is rotated to drive the end face gear 41 to rotate, so that the rotating shaft 43 and the end face gear 41 will not move up and down, affecting the opening and closing of the liquid outlet pipe 13 and the regulation of the flow rate.

[0030] Reference Figure 7 and Figure 8 The reset assembly 7 includes a guide groove 73 provided in the rotating shaft 43, a guide rod 74 slidably connected to the inner side of the guide groove 73, the guide rod 74 is fixedly connected to the pressure rod 64, a reset ring 71 fixedly sleeved on the outer side of the pressure rod 64, a reset spring 72 fixedly connected between the reset ring 71 and the rotating shaft 43, and the reset spring 72 is sleeved on the outer side of the pressure rod 64.

[0031] Specifically, the pressing rod 64 is pressed to move downward, driving the reset ring 71 to move downward, stretching the reset spring 72, relaxing the pressing rod 64, and driving the reset ring 71 to move upward and reset under the action of the reset spring 72, and rotating the pressing rod 64, and driving the rotating shaft 43 to rotate under the action of the guide rod 74 and the guide groove 73. The rest of the structure is the same as that of the first embodiment.

[0032] Example 3, reference Fig. 9 and Fig.10, which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the second locking component includes a second locking assembly 8 installed on the top cover 12, and a rotating assembly 9 installed on the rotating shaft 43; the second locking assembly 8 includes a fixing ring 81 fixedly connected to the top cover 12, a slot 83 provided on the fixing ring 81, a connecting block 82 rotatably connected to the rotating shaft 43, and a block 84 fixedly connected to the connecting block 82, and the block 84 is plugged into the inner side of the slot 83.

[0033] Specifically, in the initial state, the connecting block 82 is attached to the fixing ring 81, and the clamping block 84 is clamped with the inner side of the clamping groove 83, thereby limiting the rotating shaft 43, so that the rotating shaft 43 cannot rotate, and the liquid outlet pipe 13 will not be opened and closed at will. When it is necessary to rotate the rotating shaft 43, under the action of the rotating component 9, the connecting block 82 is rotated and separated from the fixing ring 81, so that the clamping block 84 is separated from the inner side of the clamping groove 83, and then the rotating shaft 43 is no longer limited. At this time, the rotating shaft 43 can be rotated at will to open and close the liquid outlet pipe 13 and adjust the flow rate.

[0034] Reference Fig. 9 and Fig.10 The rotating assembly 9 includes a movable sleeve 91 that is limitedly slidably connected to the outside of the rotating shaft 43, the movable sleeve 91 is rotatably connected to the top cover 12, a threaded ring 92 that is threadedly connected to the top of the movable sleeve 91, a collar 93 that is fixedly connected to the bottom of the movable sleeve 91, a U-shaped seat 95 that is rotatably connected to the bottom of the threaded ring 92, a second rotating rod 97 that is rotatably connected to the inner side of the U-shaped seat 95, a through hole 94 opened on the collar 93, a first rotating rod 96 that is rotatably connected to the inner side of the through hole 94, the first rotating rod 96 is rotatably connected to the second rotating rod 97, and the connecting block 82 is fixedly connected to the first rotating rod 96.

[0035] Specifically, the threaded ring 92 is rotated to make the threaded ring 92 move up and down on the movable sleeve 91. Since the U-shaped seat 95 is rotatably connected to the threaded ring 92, the U-shaped seat 95 is driven to move up and down. When the threaded ring 92 moves downward on the movable sleeve 91, the U-shaped seat 95 is driven to move downward, so that the second rotating rod 97 rotates counterclockwise on the U-shaped seat 95, and then the first rotating rod 96 is squeezed, so that the first rotating rod 96 rotates inside the through hole 94, driving the connecting block 82 to rotate, so that the connecting block 82 is separated from the fixed ring 81, and the clamping block 84 is separated from the inner side of the clamping groove 83. At this time, the rotating shaft 43 can be rotated. When the threaded ring 92 moves upward on the movable sleeve 91, the U-shaped seat 95 is driven to move upward, so that the second rotating rod 97 rotates clockwise on the U-shaped seat 95, stretching the first rotating rod 96, so that the connecting block 82 approaches one side of the fixed ring 81, so that the clamping block 84 is plugged into the inner side of the clamping groove 83, and the rotating shaft 43 is limited. The remaining structure is the same as that of Example 2.

[0036] In summary, the working principle of the present invention is as follows: when it is necessary to open and close one of the liquid outlet pipes 13, the pressure rod 64 is pressed to make the sliding groove 63 approach the semi-conical block 62, and the semi-conical block 62 is squeezed and pushed to move the semi-conical block 62 to the inside of the sliding groove 63, so that the locking rod 53 is separated from the inner side of the locking groove 57. At this time, the rotating shaft 43 can be moved up and down, thereby driving the end face gear 41 to move up and down. Under the action of the telescopic component 3, the end face gear 41 can mesh with the corresponding bevel gear 42 on the liquid outlet pipe 13, and the pressure on the pressure rod 64 is stopped. Under the action of the reset component 7, the pressure rod 64 moves upward, and under the action of the second spring 55, the locking rod 53 is plugged into the inner side of the corresponding locking groove 57, and the rotating shaft 43 is limited so that the rotating shaft 43 will no longer move up. The second rotating rod 97 rotates counterclockwise on the U-shaped seat 95, and then squeezes the first rotating rod 96, so that the first rotating rod 96 rotates inside the through hole 94, drives the connecting block 82 to rotate, so that the connecting block 82 is separated from the fixed ring 81, and the rotating shaft 43 is rotated to drive the end gear 41 to rotate, which can drive the threaded rod 23 to rotate, so that the sealing plate 21 slides inside the tapered groove 22, and the opening and closing of the liquid outlet pipe 13 are controlled. When the flow rate of the liquid outlet pipe 13 needs to be controlled, it is only necessary to continue to rotate the rotating shaft 43 to move the sealing plate 21 inside the tapered groove 22, so that the cross-sectional area of ​​the liquid outlet of the liquid outlet pipe 13 changes, and the flow rate of the liquid outlet pipe 13 can be adjusted.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
