Description

Technical Field

[0001] The present application relates to the field of speed control valves, and particularly to a speed control valve that is convenient for disassembly and assembly. Background Art

[0002] The speed control valve directly adjusts the fluid flow by changing the size of the throttle orifice, and then controls the movement speed of the actuating element (such as a hydraulic cylinder, a pneumatic motor). This adjustment can achieve constant speed or variable speed control, and is widely used in construction machinery and automation equipment.

[0003] However, one end of the traditional speed control valve is threadedly connected to the hydraulic cylinder. Therefore, a large amount of time is required to twist the speed control valve each time for disassembly and assembly. This process is time-consuming and laborious, making it inconvenient for the quick disassembly and assembly of the speed control valve. Moreover, there will be gaps during threaded connection. Therefore, in order to ensure the sealing performance after threaded connection, sealing tape needs to be wound around the outside of the thread each time for disassembly and assembly. Before winding the new sealing tape, it is also necessary to clean the old sealing tape remaining inside the thread, which wastes a lot of time and is not convenient for the quick disassembly and assembly of the speed control valve. In addition, when the sealing tape is wound less, it is also easy to cause fluid leakage, which will affect the sealing performance after installation. Generally, the speed control valve adjusts the size of the throttle orifice by rotating the adjustment knob at its top. Since the adjustment knob is directly exposed outside after adjustment, it is easily accidentally touched and rotated, which will cause the size of the throttle orifice to change, resulting in poor stability during use. Moreover, a quick connector is generally installed at the other end of the speed control valve for the quick connection of the fluid conveying pipeline. When it is necessary to pull out the fluid conveying pipeline, it is necessary to press the end of the quick connector. Since the area of its end is small, the contact area with the finger during pressing is small. It is not only difficult to apply force, but also the small contact area will make the finger feel uncomfortable, resulting in poor convenience and comfort during operation. At the same time, when pressing, it may be pressed unilaterally, so that the quick connector is unevenly stressed, which is likely to have an adverse effect on the sealing performance of the quick connector. Summary of the Invention

[0004] In order to enable the quick disassembly and assembly of the speed control valve, improve the convenience of disassembly and assembly operations, and be able to avoid the adjustment knob from being accidentally touched and rotated when the throttle orifice size does not need to be adjusted, and at the same time be able to facilitate the pressing of the end of the quick connector when pulling out the fluid conveying pipeline, the present application provides a speed control valve that is convenient for disassembly and assembly.

[0005] A speed control valve that is convenient for disassembly and assembly provided by the present application adopts the following technical solutions:

[0006] A speed control valve that is convenient for disassembly and assembly, including a speed control valve body. The bottom end of the speed control valve body is engaged with a base. A fixing structure is provided on the speed control valve body. The fixing structure includes a pressing sleeve and a first spring. The bottom end of the speed control valve body is slidably connected with the pressing sleeve. The bottom end of the pressing sleeve abuts against the speed control valve body. A first spring is provided inside the pressing sleeve. One end of the first spring abuts against the pressing sleeve and the other end abuts against the speed control valve body. Two pressing blocks are fixedly connected to the pressing sleeve. A slider is slidably connected to the pressing block. A clamping block is fixedly connected to the bottom end of the slider. An annular groove is provided on the base. The two clamping blocks are engaged with the annular groove. A second spring abuts between the clamping block and the pressing block.

[0007] By adopting the above technical solution, after the installation is completed, under the action of the elastic force of the first spring, the speed control valve body and the base can be tightly abutted, thereby improving the sealing performance between the speed control valve body and the base. When it is necessary to disassemble the speed control valve body, the slider can be pushed reversely. The slider will drive the clamping block to move away from the annular groove. When the clamping block is not engaged with the annular groove, the first spring will elongate and drive the pressing sleeve to reset. Then, the speed control valve body can be directly taken out from the inside of the base. When installing again, only need to engage the speed control valve body with the base again. Therefore, it can effectively shorten the subsequent disassembly and assembly time of the speed control valve body, improve the convenience of disassembly and assembly operations, and thus improve the overhaul and maintenance efficiency of the speed control valve body.

[0008] Optionally, the cross-section of the end of the clamping block close to the annular groove is in a trapezoidal structure, and the overall cross-section of the slider is in an L-shaped structure.

[0009] By adopting the above technical solution, since the cross-section of the end of the clamping block close to the annular groove is in a trapezoidal structure, during the process of the clamping block moving towards the base, the base will abut against the clamping block and move automatically, avoiding the need to push the slider by hand, thereby improving the convenience of operation. Since the overall cross-section of the slider is in an L-shaped structure, it is possible to apply force to the slider better when pushing the slider.

[0010] Optionally, a sealing ring is engaged at the bottom end of the speed control valve body, and the bottom end of the sealing ring abuts against the base.

[0011] By adopting the above technical solution, when the bottom end of the speed control valve body abuts tightly against the base, the sealing ring will undergo elastic deformation and be in a compressed state, thereby effectively improving the sealing performance between the base and the speed control valve body.

[0012] Optionally, a protrusion is provided on the base. The protrusion and the base are of an integral structure, and the cross-section of the protrusion is in a hexagonal structure.

[0013] By adopting the above technical solution, when the rotating base is rotated, the open-ended wrench can be stuck outside the protrusion, so as to facilitate the rotation of the base and make the connection between the base and the hydraulic cylinder more firm.

[0014] Optionally, an adjustment knob is installed on the speed control valve body. There is a rotating structure on the speed control valve body. The rotating structure includes a connecting seat and a moving sleeve. The top end of the speed control valve body is fixedly connected with the connecting seat. The outside of the connecting seat is movably connected with the moving sleeve. A fourth spring is abutted between the moving sleeve and the speed control valve body. A rotating sleeve is rotatably connected to the moving sleeve. Four guide sleeves are fixedly connected to the inside of the rotating sleeve. An insertion block is slidably connected to the inside of the guide sleeve. Multiple slots are provided at the top end of the adjustment knob.

[0015] By adopting the above technical solution, after the insertion block and the slot are engaged, the rotating sleeve can be rotated. The rotation of the rotating sleeve will drive the movement of multiple insertion blocks. The movement of multiple insertion blocks will drive the rotation of the adjustment knob, so as to realize the adjustment of the throttle opening size. After the adjustment is completed, the rotating sleeve can be released. At this time, the fourth spring will elongate and drive the movement of the moving sleeve. The moving sleeve drives the movement of the rotating sleeve. The rotation drives the movement of multiple insertion blocks until they are not engaged with the slot. Since the insertion block and the slot are not engaged at this time, when the rotating sleeve is accidentally touched, the rotating sleeve will not drive the adjustment knob to rotate together. Therefore, it is avoided that the adjustment knob is exposed outside and accidentally touched and rotated after the adjustment is completed, thus effectively improving the stability of use.

[0016] Optionally, the cross-section of the bottom end of the insertion block is in a trapezoidal structure. A third spring is abutted between the insertion block and the guide sleeve. During the process of the rotating sleeve moving towards the adjustment knob, the bottom end of the insertion block may not be directly opposite to the slot. At this time, the bottom end of the insertion block will abut against the top end of the adjustment knob during the movement and then slide inside the guide sleeve. The third spring contracts. As the rotating sleeve rotates, the end of the insertion block will be located at the top of the slot. Then the third spring will elongate and drive the insertion block to engage with the slot. Then continue to rotate the rotating sleeve. The rotating sleeve will drive the adjustment knob to rotate through the insertion block. Since the cross-section of the bottom end of the insertion block is in a trapezoidal structure, it can play a guiding role when engaging with the slot.

[0017] Optionally, a plurality of convex blocks are fixedly connected to the outside of the rotating sleeve. The plurality of convex blocks are circumferentially arrayed about the middle of the rotating sleeve.

[0018] By adopting the above technical solution, when rotating the rotating sleeve, the hand can be prevented from slipping through the plurality of convex blocks, thereby improving the stability when rotating the rotating sleeve.

[0019] Optionally, a guiding structure is provided on the connecting seat. The guiding structure includes a guiding shaft and a guiding groove. Two guiding shafts are fixedly connected to the outside of the connecting seat. Two guiding grooves are provided on the moving sleeve. The guiding shafts extend into the adjacent guiding grooves and are slidably connected with the moving sleeve.

[0020] By adopting the above technical solution, when the guide shaft moves at the inclined position in the middle of the guide groove, the moving sleeve will drive the rotating sleeve to move towards the adjusting knob. When the guide shaft moves to one end of the guide groove, the moving sleeve can be released. At this time, the moving sleeve can be limited by the cooperation of the guide shaft and the guide groove, avoiding the reset of the moving sleeve driven by the elongation of the fourth spring after the moving sleeve is released. Thus, when rotating the rotating sleeve, it is not necessary to keep pressing the rotating sleeve by hand all the time, effectively improving the operation convenience.

[0021] Optionally, a quick connector is installed on the speed control valve body, and a pressing structure is provided on the speed control valve body.

[0022] By adopting the above technical solution, the quick connection of the fluid conveying pipeline can be realized through the quick connector.

[0023] Optionally, the pressing structure includes a guide seat and a pressing rod. Two guide seats are fixedly connected to the speed control valve body. The pressing rod is slidably connected to the guide seat. One ends of the two pressing rods are in contact with the end of the quick connector. A connecting shaft is rotatably connected to the guide seat. An eccentric wheel is fixedly connected to the connecting shaft. The eccentric wheel is in contact with the other end of the pressing rod. The two connecting shafts are fixedly connected to the same handle.

[0024] By adopting the above technical solution, since the two pressing rods are respectively located on both sides of the quick connector, a relatively uniform pressure can be applied to the quick connector, avoiding damage to the quick connector due to uneven force when pressed by fingers, thus improving the operation safety. Also, it avoids the contact of fingers with the small-volume parts at the end of the quick connector, avoiding discomfort of fingers caused by the large reverse force during pressing, thus improving the operation comfort. And according to the lever principle, driving the eccentric wheel to rotate by the handle has a labor-saving effect, which can further improve the operation comfort.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the speed regulating valve body needs to be installed, the speed regulating valve body can be moved so that its bottom end is engaged with the base, and then the two pressing blocks are pressed by both hands. When the bottom end of the pressing sleeve contacts the speed regulating valve body, the block will be engaged with the ring groove. At this time, the installation of the speed regulating valve body is realized. After the installation is completed, the speed regulating valve body and the base can be pressed tightly under the action of the elastic force of the first spring. At this time, the sealing gasket is squeezed and deformed, thereby improving the sealing between the speed regulating valve body and the base. When the speed regulating valve body needs to be disassembled, it is only necessary to push the two sliders in the opposite direction at the same time so that the two blocks are not engaged with the ring groove, and then directly take the speed regulating valve body out of the base. This can effectively shorten the time for disassembly and assembly of the speed regulating valve body, improve the convenience of disassembly and assembly operations, and thus improve the efficiency of inspection and maintenance of the speed regulating valve body.

[0027] 2. When the adjustment knob is adjusted, the movable sleeve can be pressed downward first, and then the movable sleeve can be rotated in the opposite direction. During the process of rotating the movable sleeve in the opposite direction, the guide shaft will move inside the guide groove, and the rotation of the rotating sleeve will drive multiple plug-in blocks to move away from the slots. When the guide shaft moves to the horizontal position at the other end of the guide groove, the movable sleeve can be released. Since the plug-in blocks are not engaged with the slots at this time, the rotating sleeve will not drive the adjustment knob to rotate when the rotating sleeve is accidentally touched. Therefore, the adjustment knob is prevented from being exposed to the outside and accidentally touched and rotated after the adjustment is completed, thereby effectively improving the stability of use;

[0028] 3. When it is necessary to press the quick connector to pull out the fluid delivery pipeline, you only need to hold the handle and turn it to apply a relatively uniform pressure to the quick connector, avoiding damage to the quick connector due to uneven force when pressing with fingers, thereby improving the safety of operation, and avoiding contact between fingers and the smaller area at the end of the quick connector, avoiding discomfort to fingers caused by a large reverse force when pressing, thereby improving the comfort of operation, and according to the principle of leverage, driving the eccentric wheel to rotate through the handle has a labor-saving effect, which can further improve the comfort of operation.

[0037] The following further elaborates on the present application Figure 1-7 in further detail

[0038] An embodiment of the present application discloses a speed control valve that is convenient for disassembly and assembly. Referring to Figure 1 、 Figure 3 、 Figure 5 and Figure 7 , a speed control valve that is convenient for disassembly and assembly includes a speed control valve body 1. The bottom end of the speed control valve body 1 is engaged with a base 2. A protrusion 3 is provided on the base 2. A sealing ring 9 is engaged at the bottom end of the speed control valve body 1. The bottom end of the sealing ring 9 abuts against the base 2. A fixing structure 4 is provided on the speed control valve body 1

[0039] Since the cross-section of the locking block 406 near the annular groove 407 is in a trapezoidal structure, during the movement of the locking block 406 towards the base 2, the base 2 will abut against the locking block 406 and move automatically, avoiding the need to push the slider 404 by hand, thereby improving the convenience of operation. When the bottom end of the compression sleeve 401 abuts against the speed control valve body 1, the second spring 405 will elongate and drive the locking block 406 towards the annular groove 407 and engage with the annular groove 407. At this time, the pressing block 403 can be released, and the compression sleeve 401 will not reset under the action of the first spring 402, thus realizing the installation of the speed control valve body 1

[0040] Push the slider 404 in the reverse direction, the slider 404 will drive the block 406 to move away from the annular groove 407, and the second spring 405 will contract. When the block 406 and the annular groove 407 are not engaged, the first spring 402 will extend and drive the pressing sleeve 401 to reset. Then, the speed control valve body 1 can be directly taken out from the inside of the base 2. When installing it again, you only need to engage the speed control valve body 1 with the base 2 again.

[0041] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 An adjusting knob 10 is installed on the speed regulating valve body 1, a rotating structure 6 is provided on the speed regulating valve body 1, a guiding structure 5 is provided on the connecting seat 607, the guiding structure 5 includes a guiding shaft 501 and a guiding groove 502, two guiding shafts 501 are fixedly connected to the outer side of the connecting seat 607, two guiding grooves 502 are provided on the movable sleeve 608, and the guide shaft 501 extends to the inside of the adjacent guiding groove 502 and is slidably connected to the movable sleeve 608.

[0042] The movable sleeve 608 can be limited by the guide shaft 501 and the guide groove 502 to prevent the fourth spring 609 from extending and resetting the movable sleeve 608 after the movable sleeve 608 is released, thereby avoiding the need to press the rotating sleeve 601 with hands during the rotation of the rotating sleeve 601, thereby effectively improving the convenience of operation. At this time, when the plug block 604 is engaged with the slot 606, the rotating sleeve 601 can be rotated.

[0043] Reference Figure 1 and Figure 2 A quick connector 8 is installed on the speed regulating valve body 1 , and a pressing structure 7 is provided on the speed regulating valve body 1 . The pressing structure 7 includes a guide seat 701 and a pressing rod 702 .

[0044] The rotation of the eccentric wheel 704 will interfere with the sliding of the push rod 702 on the guide seat 701. The simultaneous movement of the two push rods 702 will press the quick connector 8. Since the two push rods 702 are respectively located on both sides of the quick connector 8, a relatively uniform pressure can be applied to the quick connector 8, avoiding damage to the quick connector 8 due to uneven force when pressed by fingers.

[0045] The implementation principle of a speed control valve that is easy to disassemble and assemble disclosed in the embodiments of the present application is as follows: During use, when the speed control valve body 1 is installed for the first time, the base 2 can be threadedly connected to the hydraulic cylinder first. After the base 2 is installed, the speed control valve body 1 can be moved so that its bottom end engages with the base 2. Then, by pressing two pressing blocks 403 with both hands, the movement of the two pressing blocks 403 will drive the compression sleeve 401 to move, and the first spring 402 will contract. At the same time, the movement of the pressing block 403 will drive the slider 404 to move, and the movement of the slider 404 will drive the latch 406 to move. When the bottom end of the compression sleeve 401 abuts against the speed control valve body 1, the second spring 405 will extend and drive the latch 406 to move towards the annular groove 407 and engage with the annular groove 407. At this time, the pressing block 403 can be released, and the compression sleeve 401 will not reset under the action of the first spring 402, thus realizing the installation of the speed control valve body 1. After the speed control valve body 1 is installed, under the action of the elastic force of the first spring 402, the speed control valve body 1 and the base 2 can be tightly abutted, and at the same time, the sealing ring 9 is squeezed and deformed, so as to improve the sealing performance between the speed control valve body 1 and the base 2. When the speed control valve body 1 needs to be disassembled, the slider 404 can be pushed reversely, and the slider 404 will drive the latch 406 to move away from the annular groove 407, and the second spring 405 will contract. When the latch 406 is not engaged with the annular groove 407, the first spring 402 will extend and drive the compression sleeve 401 to reset, and then the speed control valve body 1 can be directly taken out from the inside of the base 2. When installing again, only the speed control valve body 1 needs to be engaged with the base 2 again, so that the subsequent disassembly and assembly time of the speed control valve body 1 can be effectively shortened, the convenience of its disassembly and assembly operation can be improved, and thus the maintenance efficiency of the speed control valve body 1 can be improved;

[0046] When it is necessary to rotate the adjustment knob 10, the movable sleeve 608 can be rotated. During the rotation of the movable sleeve 608, it will drive the two guide grooves 502 to move. When the guide grooves 502 move, the guide shaft 501 will move inside the guide grooves 502. When the guide shaft 501 moves at the inclined position in the middle of the guide groove 502, the movable sleeve 608 will drive the rotating sleeve 601 to move towards the adjustment knob 10, and the fourth spring 609 will contract. The movement of the rotating sleeve 601 will drive a plurality of guide sleeves 603 to move, and the insertion block 604 will move towards the insertion slot 606 together with the guide sleeve 603. When the guide shaft 501 moves to one end of the guide groove 502, the movable sleeve 608 can be released. At this time, the movable sleeve 608 can be limited by the cooperation of the guide shaft 501 and the guide groove 502, avoiding the fourth spring 609 from stretching and driving the movable sleeve 608 to reset after the movable sleeve 608 is released. Thus, when rotating the rotating sleeve 601, it is not necessary to always press the rotating sleeve 601 by hand, effectively improving the operation convenience. Since the insertion block 604 is engaged with the insertion slot 606 at this time, the rotating sleeve 601 can be rotated. The rotation of the rotating sleeve 601 will drive a plurality of insertion blocks 604 to move, and the movement of the plurality of insertion blocks 604 will drive the adjustment knob 10 to rotate. By rotating the adjustment knob 10, the adjustment of the throttle opening size can be realized. After the adjustment knob 10 is adjusted, the movable sleeve 608 can be first pressed downward, and then the movable sleeve 608 is rotated in the reverse direction. During the reverse rotation of the movable sleeve 608, the guide shaft 501 will move inside the guide groove 502. At the same time, the rotation of the rotating sleeve 601 drives a plurality of insertion blocks 604 to move away from the insertion slot 606. When the guide shaft 501 moves to the horizontal position at the other end of the guide groove 502, the movable sleeve 608 can be released. Since the insertion block 604 is not engaged with the insertion slot 606 at this time, when the rotating sleeve 601 is accidentally touched, the rotating sleeve 601 will not drive the adjustment knob 10 to rotate together. Therefore, it is avoided that the adjustment knob 10 is exposed outside and accidentally rotated after the adjustment is completed, effectively improving the use stability;

[0047] The quick connector 8 can realize a quick connection between the speed regulating valve body 1 and the fluid conveying pipeline. When the quick connector 8 needs to be pressed to pull out the fluid conveying pipeline, the handle 705 can be held and then rotated. The rotation of the handle 705 will drive the two connecting shafts 703 to rotate. The rotation of the connecting shaft 703 will drive the eccentric wheel 704 to rotate. The rotation of the eccentric wheel 704 will resist the sliding of the push rod 702 on the guide seat 701. The simultaneous movement of the two push rods 702 will realize the pressing of the quick connector 8. Since the two push rods 702 are respectively located on both sides of the quick connector 8, a relatively uniform pressure can be applied to the quick connector 8, which avoids the quick connector 8 being damaged due to uneven force when pressed by fingers, thereby improving the safety of operation, avoiding the contact between the fingers and the smaller part of the end of the quick connector 8, avoiding the discomfort of the fingers caused by the large reverse force when pressing, thereby improving the comfort of operation, and according to the principle of the lever, driving the eccentric wheel 704 to rotate by the handle 705 has a labor-saving effect, thereby further improving the comfort of operation.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
