Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve groups, and specifically relates to a combined hydraulic valve group. Background Technique

[0002] A hydraulic valve is an automated component operated by pressure oil. It is controlled by the pressure oil of a distribution valve and is usually used in combination with an electromagnetic distribution valve. It can be used to remotely control the on / off of the oil, gas, and water pipeline systems of a hydropower station. Most hydraulic valve groups are directly installed on a hydraulic pump station, but there are still some problems.

[0003] For example, the patent document with the publication number CN213145845U discloses: "A hydraulic valve group control system, including an installation frame. There are two installation frames, both of which are in a U-shaped structure. Installation holes are opened at the four corners of the upper ends of the two installation frames. The left and right parts of the upper ends of the two installation frames are respectively inserted and fixedly connected with adjusting devices. A connecting plate is fixedly connected between the upper ends of the four adjusting devices. Shock-absorbing devices are fixedly connected to the four corners of the upper end of the connecting plate. A fixing device is fixedly connected between the upper ends of the four shock-absorbing devices. A valve group body is fixedly connected to the upper end of the fixing device. A pressure gauge is fixedly connected to the left part of the upper end of the valve group body. In the hydraulic valve group control system of the present utility model, by setting the adjusting device, the height adjustment of the hydraulic valve group is realized. By setting the shock-absorbing device, the shock-absorbing effect is improved, and the service life of the valve group is prolonged. By setting the fixing device, hydraulic valve groups of different specifications can be fixed". By rotating the adjusting handle, the height of the installed hydraulic valve group can be adjusted, which is convenient for the connection operation between the hydraulic valve group and other devices. Through the cooperation of the elasticity of the shock-absorbing spring and the telescoping of the telescopic cylinder, the vibration generated during the operation of the hydraulic valve group can be effectively reduced, the shock-absorbing effect is improved, and thus the service life of the hydraulic valve group is prolonged.

[0004] However, when the two sets of clamping plates of the above device fix the hydraulic valve body, since the shock-absorbing spring vibrates and shakes during operation, under the influence of the linkage of the shock-absorbing spring, it will drive the fixing device at the top to shake together with the hydraulic valve, resulting in a risk of detachment at the connection end between the hydraulic valve and the external pipeline, and the consequence that the hydraulic valve cannot work properly. Therefore, a hydraulic valve group with better fixing effect is needed to solve the above problems. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a combined hydraulic valve group to solve the problem of poor fixing effect caused by the vibration of the shock-absorbing spring during operation as mentioned in the above background technique.

[0026] It includes: a combined rack 1, a support rack 2 is fixedly connected to the top of the combined rack 1, a connecting bottom rack 3 is fixedly connected to the top of the support rack 2, connecting bottom plates 4 are fixedly connected to both the left and right sides of the connecting bottom rack 3, connecting rods 5 are fixedly connected to both the front and rear ends of the top of the connecting bottom plate 4, a limiting plate 6 is fixedly connected to the top end of the connecting rod 5, a connecting top plate 7 is slidably connected to the surface of the connecting rod 5, a connecting top rack 8 is fixedly connected to the middle of the connecting top plate 7, a fixing block 9 is slidably connected to the surface of the connecting rod 5, and the bottom of the fixing block 9 is fixedly connected to the top of the connecting top plate 7. A screw rod 10 is threadedly connected to the inner wall of the fixing block 9, a clamping block 11 is rotatably connected to the front end of the screw rod 10, and the surface of the clamping block 11 is slidably connected to the inner wall of the fixing block 9. A rotating disk 12 is fixedly connected to the tail end of the screw rod 10. Clamping rings 13 are fixedly connected to both the front and rear sides of the connecting top rack 8 and the connecting bottom rack 3. An anti-slip pad 14 is fixedly connected to one side of the connecting rod 5.

[0027] When fixing the hydraulic valve with this device, pull the connecting top rack 8 upward, so that the connecting top rack 8 drives the connecting top plate 7 to slide and move upward on the surface of the connecting rod 5. Then place the hydraulic valve on the top of the connecting bottom rack 3, and insert the clamping ring 13 into the annular grooves on both the front and rear sides of the hydraulic valve, so that the hydraulic valve cannot move back and forth. Then press the connecting top rack 8 downward, so that the bottom of the connecting top rack 8 contacts the hydraulic valve, and the top clamping ring 13 is inserted into the annular groove of the hydraulic valve. At this time, the hydraulic valve is restricted and cannot move back and forth. At the same time, the connecting top rack 8 drives the left and right connecting top plates 7 to move downward on the surface of the connecting rod 5, and the connecting top plate 7 drives the fixing block 9 to move downward. Then rotate the rotating disk 12, so that the rotating disk 12 drives the screw rod 10 at the back to rotate, and the screw rod 10 drives the clamping block 11 at the front to move forward and contact the anti-slip pad 14, thereby fixing the connecting rod 5, and then completing the fixing of the hydraulic valve.

[0028] Please refer to Figure 2 and Figure 6 , T-shaped sliders 15 are fixedly connected to both the front and rear sides of the top of the combined rack 1. A protective rack 16 is slidably connected to the surface of the T-shaped slider 15. A grip 17 is fixedly connected to the top of the protective rack 16. Anti-slip lines are provided on the surface of the grip 17. Protective plates 18 are slidably connected to the inner walls of both the front and rear sides of the protective rack 16.

A connecting plate 20 is fixedly connected to the tail of the support rod 19. A plugging rod 21 is inserted through the inner wall of the connecting plate 20, and the bottom end of the plugging rod 21 is inserted into the inner wall of the protective rack 16.

[0029] When protecting the fixing device with this device, after the hydraulic valve is fixed, slide the protective frame 16 from the left and right ends of the T-shaped slider 15, so that the T-shaped slider 15 slides towards the middle. At this time, the front and rear ends of the hydraulic valve abut against and squeeze the protective plate 18, so that the inclined grooves on both sides of the protective plate 18 are squeezed to push the inner wall of the protective frame 16, and then the protective frame 16 can be continuously slid to the top of the combined frame 1. Then rotate the support rod 19 so that the support rod 19 rotates perpendicular to the protective frame 16, and then insert the insertion rod 21 downward so that the insertion rod 21 is inserted into the inner wall of the protective frame 16, so that the support rod 19 can support the front end of the protective frame 16, thus completing the installation of the protective frame 16.

[0030] Working principle: Pull the connecting top frame 8 upward, then place the hydraulic valve on the top of the connecting bottom frame 3, and make the clamping ring 13 insert into the arc grooves on the front and rear sides of the hydraulic valve. Then press the connecting top frame 8 downward so that the bottom of the connecting top frame 8 fits with the hydraulic valve. Then rotate the rotating disc 12 so that it drives the clamping block 11 to move forward and fit with the anti-slip pad 14, so that the anti-slip lines in front of the clamping block 11 have a large friction with the anti-slip pad 14, thus fixing the connecting rod 5, and then completing the connection and fixing of the hydraulic valve. Then slide the protective frame 16 onto the surface of the T-shaped slider 15, and make the hydraulic valve squeeze the protective plate 18. At this time, the inclined sides on the left and right sides of the protective plate 18 are squeezed, so that the protective plate 18 is pushed upward to the inner wall of the protective frame 16, thus completing the installation of the protective frame 16. Then rotate the support rod 19 so that the bottom end of the support rod 19 touches the protective frame 16, and then insert the insertion rod 21 downward so that the insertion rod 21 is inserted into the inner wall of the protective frame 16, and then complete the support of the protective frame 16, so that the protective frame 16 is at the top of the fixing device to facilitate the protection of the device.
