Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a hydraulic valve group. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). When hydraulic oil is introduced into the inlet port of the hydraulic cylinder, the hydraulic oil comes out from the outlet port of the hydraulic cylinder, thereby completing the extension action of the hydraulic cylinder. When hydraulic oil is introduced into the outlet port of the hydraulic cylinder, the hydraulic oil comes out from the inlet port of the hydraulic cylinder, thereby completing the retraction action of the hydraulic cylinder. When multiple hydraulic cylinders need to be extended or retracted, multiple groups of hydraulic valve groups are required to work corresponding to the multiple hydraulic cylinders respectively.

[0003] In order to facilitate the installation and disassembly of the hydraulic valve group, the prior art has made many improvements to the hydraulic valve group. For example, the patent with patent publication number CN220505466U discloses a hydraulic valve group that is easy to disassemble, including a bottom plate and a valve body, a fixed plate is fixedly installed on one side of the top of the bottom plate, the valve body cooperates with the fixed plate, a movable plate is slidably installed on the top of the bottom plate, two slide grooves are provided on one side of the top of the bottom plate, two sliders are fixedly installed on the bottom of the movable plate, the sliders are slidably connected with the slide grooves, hinge grooves are provided inside both sides of the fixed plate, and hinges are movably installed inside the hinge grooves. The beneficial effects of the utility model are as follows: through the cooperation of the fixed plate, the movable plate, the slide groove, the slider, the hinge groove, the hinge, the fixed rod, the connecting groove, the socket, the pin, the pull plate and the spring, when the valve body needs to be disassembled, it only needs to pull up the pin to make it withdrawn from the socket to release the limit with the fixed rod, and then the movable plate can be pulled to one side through the slide groove and the slider to remove the valve body, and the disassembly is convenient and quick.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, the valve body is fixed by a fixing rod through a pin cooperating with a fixing rod, while in the existing situation, it is necessary to install several valve bodies of the same model on the valve seat to form a hydraulic valve group. When multiple valve bodies need to be installed on the valve seat, they need to be installed one by one when installing through the above-mentioned comparative document structure, which makes it more troublesome to install several valve bodies. In addition, the existing valve body needs to be modified in the above-mentioned comparative document, which increases the cost of installing the hydraulic valve group. Therefore, there is an urgent need in this field to improve the hydraulic valve group to solve the defects of the prior art. Utility Model Content

When it is necessary to install several valve bodies 2 on the valve seat 1, several valve bodies 2 are placed on the upper side of the valve seat 1, and the valve body 2 is aligned with the hydraulic channel on the valve seat 1, and the two adjusting screw rods 7 are rotated at the same time. When the adjusting screw rod 7 rotates, it drives the fixed frame 6 to move downward, and the fixed frame 6 drives the movable seat 4 to move downward in the supporting frame 3. The movable seat 4 also drives several clamping frames 5 to move downward, and the clamping frames 5 are clamped on the sides of several valve bodies 2. Tighten the adjusting screw rod 7 and tighten the first limiting nut 8 threadedly connected to the side of the adjusting screw rod 7 to limit the position of the adjusting screw rod 7, so as to achieve the effect of fixing multiple valve bodies 2 at the same time, facilitate the installation of the hydraulic valve group, and do not need to make any improvements to the existing valve body 2, thereby reducing the cost of installing the hydraulic valve group.

[0032] Embodiment 2

[0033] See also Figure 2 , Figure 3 and Figure 4 The present embodiment includes the above-mentioned embodiment, which further includes: a first moving groove 9 is formed through the upper and lower sides of the moving seat 4, and second moving grooves 10 are formed in the opposite side walls of the first moving groove 9, and a plurality of moving blocks 11 are slidably connected in the second moving groove 10, and an adjusting bolt 12 is penetrated and threadedly connected on the moving block 11, and the lower end of the adjusting bolt 12 is rotatably connected to the upper side of the clamping frame 5, and a second limiting nut 13 is threadedly connected to the upper side of the adjusting bolt 12.
