Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a mechanism for controlling the flow rate of a hydraulic valve. Background Technique

[0002] A hydraulic valve is an automated component operated by pressure oil. It is controlled by the pressure oil of a distributing valve and is usually used in combination with an electromagnetic distributing valve, and is commonly used in the field of construction machinery.

[0003] During the use of existing hydraulic valves, they are generally connected to the pipelines at both ends through threaded connections. Although the threaded connection method has strong stability, since most of the connection fittings of hydraulic valves are metal fittings with poor plasticity, when connecting to external pipelines through threads, when the external pipelines are also made of metal materials, a strong stability will be generated between the two, and there is a risk of thread slipping, making the process of disassembly or installation more cumbersome and taking up a certain amount of time cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mechanism for controlling the flow rate of a hydraulic valve to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A mechanism for controlling the flow rate of a hydraulic valve, including a hydraulic valve body. Both ends of the hydraulic valve body are threadedly connected with a first mounting member through pipelines. At both the upper and lower ends inside the first mounting member, a T-shaped slider is installed. One end of the first mounting member away from the hydraulic valve body is installed with an adjusting pipeline. The other end of the adjusting pipeline is slidably connected with a second mounting member. The other end of the second mounting member is installed with an external pipeline. Two longitudinal T-shaped chutes are symmetrically opened at one end of the adjusting pipeline close to the first mounting member. The upper end opening of the T-shaped chute extends to the outside of the adjusting pipeline. At the position where the end of the T-shaped chute is located inside the adjusting pipeline, a transverse extension slot is opened. The sizes of the extension slot and the T-shaped chute are both adapted to the size of the T-shaped slider. A triangular clamping block is telescopically installed on the side wall of the extension slot.

[0006] Preferably, a cavity communicating with the extension slot is opened inside the adjusting pipeline. A rack plate is slidably connected inside the cavity. One end of the rack plate is connected to the triangular clamping block.

[0007] Preferably, a driving nut is rotatably connected at the position on the surface of the adjusting pipeline on one side of the T-shaped chute. The lower end of the driving nut is connected with a driven gear through a rotating shaft. One end of the driven gear is meshed with the rack plate.

[0008] Preferably, one end of the adjusting pipe close to the first mounting member is provided with a sealed annular clamping groove, and a sealing gasket is arranged inside the sealed annular clamping groove.

[0009] Preferably, an installation ring plate is installed inside the first mounting member, and a sealed annular clamping block is installed at one end of the installation ring plate close to the adjusting pipe. The sizes of the sealed annular clamping block and the sealed annular clamping groove are adapted to each other.

[0010] Preferably, a limiting bin is opened at one end of the first mounting member close to the adjusting pipe, a limiting ring plate is installed at the other end of the limiting bin, an extension pipe is installed at one end of the adjusting pipe close to the first mounting member, the extension pipe passes through the limiting ring plate and enters the inside of the limiting bin, a limiting plate is installed at one end of the extension pipe located inside the limiting bin, and the limiting plate is slidably connected with the limiting bin.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. For the mechanism capable of controlling the flow rate of the hydraulic valve proposed by the utility model, the adjusting pipe is slidably installed into the inside of the second mounting member. At this time, the external pipeline is communicated with the adjusting pipe through the second mounting member. Then, the first mounting member is threadedly connected to both ends of the hydraulic valve body. After aligning the two T-shaped sliders inside the first mounting member with the two T-shaped sliding grooves on the surface of the adjusting pipe, the T-shaped sliders are slidably inserted into the inside of the T-shaped sliding grooves. When the T-shaped sliders move to the end of the T-shaped sliding grooves, the adjusting pipe is rotated to make the T-shaped sliders move into the inside of the extension clamping grooves, and the triangular clamping blocks are driven into the inside of the cavity by the active nuts. When the T-shaped sliders move to the end of the extension clamping grooves, the triangular clamping blocks are driven into the extension clamping grooves by the active nuts again. The T-shaped sliders are restricted by the triangular clamping blocks. By setting the detachable connection relationship between the adjusting pipe and the first mounting member, during disassembly, only the position of the triangular clamping blocks needs to be adjusted through the active nuts to make the triangular clamping blocks enter the inside of the cavity. At this time, by rotating the adjusting pipe, the T-shaped clamping blocks can be separated from the extension clamping grooves, and then the first mounting member is pulled outwards to complete the separation of the adjusting pipe and the first mounting member. The installation and disassembly processes are simple and convenient, saving the user's time cost to a certain extent.

[0013] 2. The mechanism for controlling the flow of the hydraulic valve proposed in the utility model sets a limit bin inside the second mounting part, and the regulating pipe is slidably connected with the limit bin through the limit plate, so that the regulating pipe can move horizontally within a certain range inside the second mounting part. Since the position of the external pipe is fixed, when installing the hydraulic valve body, the user can first move the regulating pipes on both sides toward the direction of the second mounting part, and then put the hydraulic valve body into the two regulating pipes. By changing the position of the regulating pipes, the regulating pipes and the hydraulic valve body can be connected. The regulating pipes with adjustable positions can greatly facilitate the user to install and disassemble the hydraulic valve body inside the two regulating pipes. BRIEF DESCRIPTION OF THE DRAWINGS

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] As Figures 1 to 6 shown, the mechanism for controlling the flow rate of the hydraulic valve in this embodiment includes a hydraulic valve body 1. A first mounting member 2 is threadedly connected to both ends of the hydraulic valve body 1 through pipes. The first mounting member 2 is in the shape of an annular pipe and is threadedly connected between one end and the hydraulic valve body 1. A T-shaped slider 15 is installed at both the upper and lower ends inside the first mounting member 2. The T-shaped sliders 15 have the same shape, opposite directions, and are symmetrically arranged. A regulating pipe 3 is installed at the end of the first mounting member 2 away from the hydraulic valve body 1. The other end of the regulating pipe 3 is slidably connected to a second mounting member 4. The other end of the second mounting member 4 is installed with an external connecting pipe 5. The external connecting pipe 5, the second mounting member 4, and the regulating pipe 3 are communicated with each other. Two longitudinal T-shaped chutes 7 are symmetrically opened at one end of the regulating pipe 3 close to the first mounting member 2. The two T-shaped chutes 7 have the same size and opposite directions, and are symmetrically arranged with each other. The upper end opening of the T-shaped chute 7 extends to the outside of the regulating pipe 3. The two T-shaped sliders 15 are respectively slidably connected to a T-shaped chute 7. A transverse extension slot 10 is opened at the position of the end of the T-shaped chute 7 inside the regulating pipe 3. It should be noted that the extension slots 10 provided on one side of the two T-shaped chutes 7 are in opposite directions to each other. For example, an extension slot 10 is opened at the left end of the upper T-shaped chute 7, and an extension slot 10 is opened at the right end of the lower T-shaped chute 7. The two extension slots 10 cannot be located on the same side of the T-shaped chute 7. The directions of the T-shaped chute 7 and the extension slot 10 are perpendicular to each other. The sizes of the extension slot 10 and the T-shaped chute 7 are both adapted to the size of the T-shaped slider 15. A triangular clamping block 9 is telescopically installed on the side wall of the extension slot 10. The triangular clamping block 9 can be telescoped on the side wall of the extension slot 10. When the T-shaped slider 15 moves to the end of the T-shaped chute 7, the regulating pipe 3 is rotated so that the T-shaped slider 15 moves into the extension slot 10, and the triangular clamping block 9 is operated to enter the cavity. When the T-shaped slider 15 moves to the end of the extension slot 10, the triangular clamping block 9 is further operated to move into the extension slot 10, and the T-shaped slider 15 is restricted by the triangular clamping block 9.

[0024] Specifically, a cavity communicating with the extension slot 10 is provided inside the adjusting pipe 3, and a rack plate 11 is slidably connected inside the cavity, and one end of the rack plate 11 is connected to the triangular block 9. An active nut 8 is rotatably connected to the surface of the adjusting pipe 3 at one side of the T-shaped slot 7, and the lower end of the active nut 8 is connected to a driven gear 12 through a rotating shaft, and one end of the driven gear 12 is meshed with the rack plate 11. The driven gear 12 is rotated by rotating the active nut 8, and the driven gear 12 and the rack plate 11 are meshed. When the driven gear 12 rotates, the rack plate 11 will move horizontally, thereby driving the triangular block 9 to move horizontally, so that the triangular block 9 can be telescopically moved inside the extension slot 10.

[0025] Furthermore, a sealing annular groove 6 is opened at one end of the adjusting pipe 3 close to the first mounting member 2, a sealing gasket is arranged inside the sealing annular groove 6, a mounting ring plate 13 is installed inside the first mounting member 2, a sealing annular block 14 is installed at one end of the mounting ring plate 13 close to the adjusting pipe 3, the size of the sealing annular block 14 and the sealing annular groove 6 are matched, when the adjusting pipe 3 and the first mounting member 2 are connected, the sealing annular block 14 will enter the sealing annular groove 6, it should be noted that the sealing annular block 14 can rotate inside the sealing annular groove 6, and the sealing between the adjusting pipe 3 and the first mounting member 2 can be enhanced by setting the sealing gasket.

[0026] Furthermore, a limiting bin 19 is provided at one end of the first mounting member 2 close to the regulating pipe 3, and a limiting ring plate 16 is installed at the other end of the limiting bin 19. An extension pipe 17 is installed at one end of the regulating pipe 3 close to the first mounting member 2, and the extension pipe 17 passes through the limiting ring plate 16 and enters the interior of the limiting bin 19. A limiting plate 18 is installed at one end of the extension pipe 17 located inside the limiting bin 19, and the limiting plate 18 and the limiting bin 19 are slidably connected. By arranging the limiting bin 19 inside the second mounting member 4, the regulating pipe 3 is slidably connected to the limiting bin 19 through the limiting plate 18. The second mounting member 4 is connected so that the regulating pipe 3 can move horizontally within a certain range inside the second mounting member 4. Since the position of the external pipe 5 is fixed, when installing the hydraulic valve body 1, the user can first move the regulating pipes 3 on both sides toward the second mounting member 4, and then put the hydraulic valve body 1 into the two regulating pipes 3. By changing the position of the regulating pipes 3, the regulating pipes 3 and the hydraulic valve body 1 can be connected. The regulating pipes 3 with adjustable position can greatly facilitate the user to install and disassemble the hydraulic valve body 1 inside the two regulating pipes 3.

[0027] The usage method of this embodiment is as follows: By sliding the adjustment pipe 3 into the interior of the second mounting member 4, at this time, the external pipe 5 communicates with the adjustment pipe 3 through the second mounting member 4. Then, thread the first mounting member 2 onto both ends of the hydraulic valve body 1. After aligning the two T-shaped sliders 15 inside the first mounting member 2 with the two T-shaped chutes 7 on the surface of the adjustment pipe 3, slide the T-shaped sliders 15 into the interior of the T-shaped chutes 7. When the T-shaped sliders 15 move to the end of the T-shaped chutes 7, rotate the adjustment pipe 3 so that the T-shaped sliders 15 move into the interior of the extended card slots 10, and drive the triangular latch 9 into the interior of the cavity through the active nut 8. When the T-shaped sliders 15 move to the end of the extended card slots 10, drive the triangular latch 9 to move into the extended card slots 10 through the active nut 8, and restrict the T-shaped sliders 15 through the triangular latch 9. By setting the detachable connection relationship between the adjustment pipe 3 and the first mounting member 2, during disassembly, only need to adjust the position of the triangular latch 9 through the active nut 8 so that the triangular latch 9 enters the interior of the cavity. At this time, rotate the adjustment pipe 3, then the T-shaped blocks can be disengaged from the extended card slots 10, and then pull out the first mounting member 2 outward to complete the separation of the adjustment pipe 3 and the first mounting member 2. The installation and disassembly processes are simple and convenient, saving the user's time cost to a certain extent.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
