Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve groups, in particular to a hydraulic valve group which is easy to clean and has a long service life. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure-matching valve and is usually used in combination with a solenoid pressure-matching valve. After long-term use, the hydraulic valve is prone to internal blockage due to severe oil accumulation, affecting the normal use of the device. Therefore, it needs to be cleaned during use.

[0003] As shown in the application document with the prior art publication number CN218266572U, it includes a hydraulic valve body, the top of which is rotatably connected to a turning handle, the top of which is fixedly connected to a rubber pad, and the bottom of which passes through the interior of the hydraulic valve body and is fixedly connected to a turning rod. This technical solution achieves the effect of cleaning the inside of the device through the coordinated use of the turning handle, rubber pad, turning rod, connecting rod and cleaning brush, and avoids the risk of clogging the inside of the device due to long-term use. When turning the turning handle, the rubber pad is used to increase the friction between the palm, so as to avoid the risk of falling off the turning handle during rotation. At the same time, it also avoids the risk of affecting the service life of the device due to the inside of the device to a certain extent, and improves the service life of the device as much as possible, thereby improving the practicality of the device.

[0004] However, the handlebar in the above technical solution is exposed to the outside world, which may cause deformation and damage to the handlebar due to collision and impact, affecting the convenience of the staff in operating the handlebar. At the same time, accidental touch may cause the cleaning brush to rotate and affect the operating stability of the hydraulic valve group. Utility Model Content

[0026] Refer to the instruction manual Figure 1-6 The utility model provides a long-life hydraulic valve group that is easy to clean, including a hydraulic valve body 1, wherein a maintenance component for convenient cleaning is provided inside the hydraulic valve body 1;

[0027] like Figure 2 As shown, the maintenance component includes a fixed shaft 11, which is arranged inside the hydraulic valve body 1, and the top and bottom ends of the fixed shaft 11 are movably connected to the inner wall of the hydraulic valve body 1 through bearings; two fixed plates 12 are installed at intervals on both sides of the fixed shaft 11, and a cleaning brush 13 is installed on the side of the fixed plate 12 away from the fixed shaft 11. The cleaning brush 13 on the fixed plate 12 is driven to rotate by the fixed shaft 11, so that the cleaning brush 13 can clean and maintain the inside of the hydraulic valve body 1.

[0028] like Figure 3 As shown, a knob 14 is provided on the top of the hydraulic valve body 1, and the bottom end of the knob 14 passes through the hydraulic valve body 1 and is fixed to the top of the fixed shaft 11; two spaced-apart embedding grooves 15 are provided on the top of the knob 14, and the positions of the embedding grooves 15 and the embedding block 3 correspond to each other up and down, and the support ring 5, the movable ring 6 and the movable column 2 are all arranged outside the knob 14. Through the connection between the knob 14 and the fixed shaft 11, the staff can operate the knob 14 to drive the fixed shaft 11 to rotate, and the embedding groove 15 can cooperate with the embedding block 3, so that the staff can operate the movable column 2 to drive the knob 14 to rotate.

[0029] In order to ensure the stability of the operation and maintenance components, the hydraulic valve body 1 is provided with a protective component outside to prevent collision, impact and accidental touching of the maintenance components;

[0030] like Figure 1-6As shown, the protective assembly includes a movable column 2, which is arranged on the top of the hydraulic valve body 1, and two spaced-apart inserts 3 are installed at the bottom end of the movable column 2, and a positioning ring 4 is sleeved on the outside of the movable column 2; a support ring 5 is sleeved on the outside of the movable column 2, and the bottom end of the support ring 5 is fixed to the top of the hydraulic valve body 1, and a movable ring 6 is arranged inside the top of the support ring 5, and the movable ring 6 is sleeved on the outside of the movable column 2, and a positioning groove 7 is opened on the side of the movable ring 6 close to the positioning ring 4, and the positioning ring 4 is arranged inside the positioning groove 7; a fixing ring 8 is provided at the bottom of the movable ring 6, and two spaced-apart telescopic rods 9 are provided at the bottom of the fixing ring 8, and the bottom end of the telescopic rod 9 is fixed to the top of the hydraulic valve body 1, and a spring 10 is sleeved on the outside of the top of the telescopic rod 9, and the top of the telescopic rod 9 is fixed to the bottom of the fixing ring 8.
