Description

Technical Field

[0001] The utility model relates to the technical field of oil pressure transmission valves, and specifically relates to an oil pressure transmission valve with an anti-dropping structure. Background Technique

[0002] An oil pressure transmission valve is a device for controlling the flow and pressure of oil. Its working principle is to control the flow and pressure of oil by adjusting the position of the valve core and the force of the spring. When the oil pressure valve is in the closed state, the valve core is completely attached to the valve seat, preventing the oil from passing through the valve body. When the oil needs to flow through the valve body, the position of the valve core can be changed by an external force to separate it from the valve seat by a certain distance, forming a flow-through channel, thereby allowing the oil to pass through. After long-term use of the existing oil pressure transmission valve, due to the influence of the spring force, the valve core falls off from the oil inlet sealing port, affecting the sealing effect, and the fluid oil directly enters the valve body of the oil pressure transmission valve, and the impurities in the oil are adsorbed on the internal components, which is not convenient for later cleaning.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: an oil pressure transmission valve with an anti-detachment structure, as Figure 1 , Figure 2 and Figure 4 shown, including a transmission valve structure 1. The transmission valve structure 1 includes a first valve cover 11. The first valve cover 11 and the second valve cover 12 are threadedly and sealedly connected to the hydraulic transmission valve body 13. The position of the piston 14 is adjusted by telescopic means in the hydraulic transmission valve body 13. A push rod 15 is fixed on the piston 14. A push plate 16 is threadedly connected to the push rod 15. A partition plate 17 is fixed on the inner wall of the hydraulic transmission valve body 13. A valve core 18 is snap-fitted on the partition plate 17;

[0022] Among them, the first valve cover 11, the second valve cover 12 and the hydraulic transmission valve body 13 are detachably installed, which is convenient for replacing the spring body 22 in the hydraulic transmission valve body 13 later;

[0023] Specifically, the telescopic means in this application is a hydraulic cylinder. The hydraulic cylinder is a prior art. The hydraulic cylinder on the second valve cover 12 drives the piston 14 to adjust its position through a hydraulic rod. The push plate 16 is arc-shaped to ensure that the push plate 16 fits the valve core 18;

[0024] In the above solution, the hydraulic cylinder on the second valve cover 12 drives the piston 14 to move through a hydraulic rod. The movement of the piston 14 drives the push plate 16 to push the valve core 18 on the partition plate 17 out of the sealing port through the push rod 15, so as to ensure the connection between the inlet pipe 3 and the outlet pipe 5.

[0025] As Figure 1 andFigure 2 As shown, a telescopic support assembly 2 is disassembled and installed inside the transmission valve structure 1. The telescopic support assembly 2 includes a first fixing plate 21. A spring body 22 is threadedly connected between the first fixing plate 21 and the second fixing plate 23. The first fixing plate 21 is threadedly disassembled and installed with a first valve cover 11. The second fixing plate 23 is threadedly disassembled and installed with a valve core 18. A connecting rod 24 is fixed on the valve core 18, and a slider 25 is fixed on the connecting rod 24. The slider 25 is slidably connected in a chute 26. There are two groups of chutes 26, and the two groups of chutes 26 are symmetrically arranged about the central axis of the oil pressure transmission valve body 13;

[0026] Among them, the first fixing plate 21 and the second fixing plate 23 are disassembled and installed with the first valve cover 11 and the valve core 18 through bolts, which is convenient for later replacement. The first fixing plate 21, the spring body 22 and the second fixing plate 23 are threadedly disassembled and installed, which is also convenient for later regular replacement;

[0027] In the above solution, with the auxiliary action of the self-elastic force of the spring body 22 on the first fixing plate 21, it is ensured that the valve core 18 seals the oil inlet on the partition plate 17. The push plate 16 pushes the valve core 18 to move away, and the slider 25 on the connecting rod 24 on the upper side of the valve core 18 slides in the chute 26 opened on the oil pressure transmission valve body 13, so as to prevent the valve core 18 from falling off the oil inlet on the partition plate 17 when the elastic force of the spring body 22 is insufficient, affecting the seal.

[0028] As Figure 1 and Figure 3 shown, the lower side of the transmission valve structure 1 penetrates through an oil inlet pipe 3 and an oil outlet pipe 5. The oil outlet pipe 5 is located on the left side of the oil inlet pipe 3. The lower side of the oil inlet pipe 3 is connected to a filtering assembly 4. The filtering assembly 4 includes a first oil delivery pipe 41. The first oil delivery pipe 41 is disassembled and installed with a first sealing plate 43 through a first hollow threaded connector 42. The first sealing plate 43 is threadedly sealed and connected to a filter pipe 44. A filter screen 45 is threadedly connected inside the filter pipe 44. The upper side of the filter pipe 44 is threadedly connected to a second sealing plate 46. The upper side of the second sealing plate 46 is communicated with the oil inlet pipe 3 through a second hollow threaded connector 47. There are two groups of filter screens 45, and the mesh densities of the two groups of filter screens 45 are different;

[0029] Among them, the first oil delivery pipe 41 is arranged in a T shape. The lower side of the first oil delivery pipe 41 is threadedly connected to a slag collecting pipe through a first hollow threaded connector 42. Protrusions are fixed on the filter screen 45, and the protrusions on the filter screen 45 are convenient for later rotation and disassembly;

[0030] In the above solution, the fluid oil enters the interior of the filter tube 44 through the first oil pipeline 41 and the first hollow threaded connector 42, and is filtered with the assistance of two groups of filter meshes 45 in the filter tube 44. The filtered fluid oil enters the right cavity of the oil pressure transmission valve body 13 through the second sealing plate 46 and the second hollow threaded connector 47. The fluid oil enters the left cavity of the oil pressure transmission valve body 13 through the oil inlet on the partition plate 17, and finally is discharged through the oil outlet pipe 5. When it is necessary to clean the impurities, manually rotate the first hollow threaded connector 42 at the lower side of the first oil pipeline 41, separate the slag collecting pipe from the first oil pipeline 41, and directly process the impurities. Manually rotate the first hollow threaded connector 42, the first sealing plate 43, the second sealing plate 46 and the second hollow threaded connector 47 to directly disassemble the filter tube 44. Manually rotate the filter mesh 45, and the filter mesh 45 is separated from the filter tube 44, so as to facilitate the replacement or cleaning of the filter mesh 45 in the later stage.

[0031] Working principle: When using the oil pressure transmission valve with an anti-dropping structure, connect the external power supply, filter the fluid with the assistance of the filtering component 4, and ensure that the valve core 18 always fits the oil inlet on the partition plate 17 with the assistance of the telescopic support component 2 to ensure the sealing effect.
