Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic valve maintenance equipment, and more specifically, to a hydraulic logic valve disassembly device. Background Technology

[0002] A logic valve, also known as a cone valve, is a valve with two pipe connection ports A and B and a control port C. It is connected to a pilot control valve via control port C, and uses pressure changes in the control oil circuit to control the opening and closing of the cone valve, thereby controlling the flow of oil at ports A and B. Logic valves can achieve multiple functions, such as directional control, pressure control, and flow control, depending on the control method, such as single-guided, multi-guided, flow control, and electromagnetic control. They offer advantages such as low noise, low vibration, stable mechanical operation, multi-functionality, and easy installation. They are widely used in high-pressure, high-flow, or ultra-high-flow hydraulic systems, such as large machine tools, bending machines, die-casting machines, plastic injection molding machines, copper rolling mills, and various heavy industrial machinery, vehicles, and ships.

[0003] In existing technologies, hydraulic logic valves need to be maintained regularly. While workers can easily remove the hydraulic logic valves from the equipment, the lack of specialized tools makes disassembly difficult when performing internal maintenance. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model embodiment provides a hydraulic logic valve disassembly device, including an operating handle 100 and a clamping assembly 200; the clamping assembly 200 includes a clamping seat 210 and clamping clamping members 220. The clamping seat 210 is disposed on the operating handle 100, and a receiving groove 211 is formed in the clamping seat 210. The clamping clamping members 220 are adjustablely disposed on the clamping seat 210 so that multiple clamping clamping members 220 can adjust the receiving space of the receiving groove 211; the number of clamping clamping members 220 is not less than four.

[0038] Specifically, when disassembling the hydraulic logic valve for maintenance, the operator places the clamping seat 210 on the hydraulic logic valve and then adjusts the position of the clamping clamps 220 on the clamping seat 210 so that multiple clamping clamps 220 can abut against the outer wall of the hydraulic logic valve. At this time, the operator can turn the operating handle 100 to complete the disassembly of the hydraulic logic valve body, thereby maintaining the valve core and other components. The number of clamping clamps 220 is not less than four. This setting improves the stability of disassembly, and the four clamping clamps 220 can effectively disperse the mechanical stress generated during disassembly, reduce the risk of damage to the valve body, protect the finished equipment, and improve work efficiency.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the optional embodiment, the clamping seat 210 is annular.

[0040] Specifically, the clamping seat 210 is designed in a circular shape. This design allows the clamping seat 210 to accommodate different hydraulic logic valves, enabling hydraulic logic valves of different sizes to be inserted into the clamping seat 210.

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, the clamping seat 210 is fixedly mounted on the side wall of the operating handle 100, and the operating handle 100 covers one side of the receiving groove 211.

[0042] Specifically, the clamping seat 210 is welded to the side wall of the operating handle 100. The operating handle 100 and the clamping seat 210 have at least two connection points, which improves the stability of the connection between the operating handle 100 and the clamping seat 210, thereby ensuring that it can withstand greater torque in subsequent operations.

[0043] When the clamping seat 210 is welded to the side wall of the operating handle 100, multiple adapter seats 500 are provided on the side of the clamping seat 210 away from the operating handle 100. The adapter seats 500 and the clamping seat 210 are integral structures. Each adapter seat 500 is provided with a clamping and pressing member 220, thereby increasing the depth of the receiving groove 211 on the clamping seat 210, so that the clamping seat 210 can adapt to hydraulic logic valves of different sizes.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, the operating handle 100 is connected to the outer wall of the clamping seat 210.

[0045] Specifically, one end of the operating handle 100 is welded to the outer wall of the clamping seat 210, and a reinforcing rib 300 is provided between the operating handle 100 and the outer wall of the clamping seat 210. Through the welding method and the setting of the reinforcing rib 300, the connection stability between the operating handle 100 and the clamping seat 210 can be improved.

[0046] Furthermore, one end of the operating handle 100 is welded to the outer wall of the clamping seat 210, so that the operation of the watch will not obstruct the receiving groove 211 of the clamping seat 210, allowing different types of hydraulic logic valves to be inserted into the clamping seat 210, and allowing multiple clamping clamping members 220 to be clamped at any position of the hydraulic logic valve, thus improving applicability.

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the optional solution of this embodiment, the clamping seat 210 is provided with a plurality of threaded holes 212, and the threaded holes 212 correspond one-to-one with the clamping and pressing members 220, and the clamping and pressing members 220 are installed in the threaded holes 212.

[0048] Multiple threaded holes 212 are evenly distributed on the clamping seat 210.

[0049] Specifically, the clamping seat 210 has multiple threaded holes 212, each of which is equipped with a clamping and pressing element 220. The multiple threaded holes 212 are evenly distributed on the clamping seat 210, so that the multiple clamping and pressing elements 220 are evenly distributed around the hydraulic logic valve. During disassembly, this can reduce the risk of valve body damage, protect the finished equipment, and improve work efficiency.

[0050] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, a spring 400 is provided between the clamping and pressing member 220 and the outer wall of the clamping seat 210, and the spring 400 is sleeved on the clamping and pressing member 220.

[0051] The clamping and pressing component 220 uses a clamping bolt.

[0052] Specifically, a spring 400 is fitted on the clamping and pressing member 220. The spring 400 is compressed between the clamping bolt and the outer wall of the clamping seat 210. The stability of the clamping and pressing member 220 is improved by the setting of the bolt.

[0053] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, the front end of the clamping bolt is provided with a groove for fitting the outer wall of the logic valve body.

[0054] Specifically, a groove is provided at the front end of the clamping bolt. Different groove structures allow different clamping bolts to correspond to different models of hydraulic logic valves, thereby enabling the clamping bolts to better adapt to different models of hydraulic logic valves and reducing damage to the hydraulic logic valves.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
