Description

Technical Field

[0001] This utility model relates to the field of detachable hydraulic valve technology, and in particular to a detachable hydraulic valve that is easy to maintain. Background Technology

[0002] Hydraulic valves are automated components operated by pressurized oil. They control the flow rate and direction of the fluid to open and close pipeline systems. They are typically used in combination with solenoid valves to achieve remote control of the clamping, control, and lubrication of oil, gas, and water pipeline systems in hydropower stations. Their core functions are categorized into three main types: pressure control valves, flow control valves, and directional control valves. Based on control methods, they can be classified as manual valves, electric valves, and hydraulic valves. Based on structure, they can be classified as plate valves, pipe valves, and stack valves. These components employ both direct-acting and pilot-operated principles. Electro-hydraulic proportional control valves can continuously adjust output parameters via electrical signals. Valve body design requires simplified oil circuit integration, ensuring a compact structure through the rational layout of oblique holes and process holes.

[0003] While the above technologies achieve the switching on and off of the pipeline system, the hydraulic valve design does not fully consider maintenance, and the internal pistons are mostly non-removable, leading to inconvenience in later maintenance. Therefore, a removable hydraulic valve that is easy to maintain is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a detachable hydraulic valve that is easy to maintain. It aims to solve the problem that the hydraulic valve design in the prior art does not fully consider maintenance and the internal piston is mostly non-detachable, which leads to inconvenience in later maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable hydraulic valve that is easy to maintain, comprising a housing, an outer wall element provided on the outer wall of the housing, a detachable assembly provided on the outer wall of the housing, a piston element detachably connected inside the housing, and a limit assembly provided on the outer wall of the piston element; The disassembly assembly includes a first mounting plate, the outer wall of which is fixedly connected to a second mounting plate by bolts, and the outer wall of the outer shell is fixedly connected to a mounting disc by screws.

[0006] As a further description of the above technical solution: The front wall of the No. 1 mounting plate is fixedly connected to the rear wall of the outer wall component.

[0007] As a further description of the above technical solution: The rear wall of the second mounting plate is fixedly connected to the front wall of the outer casing, and the rear wall of the mounting disc is fixedly connected to the front wall of the piston element.

[0008] As a further description of the above technical solution: The outer wall elements are provided in two sets, and the two sets of outer wall elements are distributed in a mirror image along the central axis of the outer shell.

[0009] As a further description of the above technical solution: The limiting component includes a retaining ring, and a hemispherical retaining block is elastically connected inside the retaining ring by a spring.

[0010] As a further description of the above technical solution: The outer casing has a slot inside, and the outer wall of the hemispherical block is engaged inside the slot.

[0011] As a further description of the above technical solution: One end of the spring is fixedly connected to the inside of the retaining ring, and the other end of the spring is fixedly connected to the rear wall of the hemispherical block.

[0012] As a further description of the above technical solution: The inner wall of the retaining ring is fixedly connected to the outer wall of the piston element.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting a mounting plate, bolts, and mounting disc, when maintenance is required, the outer wall components can be separated from the outer shell simply by unscrewing the bolts and removing the screws, thus releasing the fixed constraints on the piston components.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 The present invention provides an embodiment of a detachable hydraulic valve that is easy to maintain, comprising a housing 1, an outer wall element 2 provided on the outer wall of the housing 1, the outer wall element 2 being an important component of the hydraulic valve, capable of cooperating with the housing 1 to form a complete hydraulic passage, assisting the housing 1 in achieving precise control of hydraulic oil, a detachable assembly 3 provided on the outer wall of the housing 1, a piston element 5 detachably connected inside the housing 1, and a limit assembly 4 provided on the outer wall of the piston element 5; The disassembly assembly 3 includes a first mounting plate 31. The outer wall of the first mounting plate 31 is fixedly connected to a second mounting plate 34 by bolts 32. The bolts 32 are made of high-strength metal material and have good fastening performance, which can tightly fix the first mounting plate 31 and the second mounting plate 34 together to ensure the stability of the connection. The outer wall of the outer shell 1 is fixedly connected to a mounting disc 33 by screws. The front wall of the first mounting plate 31 is fixedly connected to the rear wall of the outer wall element 2. This connection method makes the first mounting plate 31 and the outer wall element 2 form an integral structure, which enhances the stability of the connection between the two and ensures that there will be no relative displacement during the operation of the hydraulic valve. The rear wall of the second mounting plate 34 is fixedly connected to the front wall of the outer shell 1, and the rear wall of the mounting disc 33 is fixedly connected to the front wall of the piston element 5. When maintenance or repair is required, quick disassembly and assembly can be achieved through the disassembly assembly 3. During disassembly, unscrew the bolts 32 connecting mounting plate 31 and mounting plate 34 to separate the outer wall component 2 from the outer casing 1. Simultaneously, remove the screws securing the mounting disc 33 to the outer casing 1, releasing the mounting disc 33 from its constraint on the piston component 5. Then, pull the piston component 5 outwards. The groove on the inner wall of the outer casing 1 will compress the hemispherical locking block 43, causing the spring 42 to contract. The hemispherical locking block 43 will then disengage from the groove, allowing the piston component 5 to be easily removed from the outer casing 1, completing the disassembly process and facilitating maintenance or replacement of internal components.

[0019] Reference Figures 2-4 The outer wall element 2 is provided in two sets, which are distributed in a mirror image along the central axis of the outer shell 1. The limiting component 4 includes a fixed retaining ring 41 with an annular structure and its inner wall adapted to the outer wall of the piston element 5. The inside of the fixed retaining ring 41 is elastically connected to a hemispherical retaining block 43 by a spring 42. The inside of the outer shell 1 is provided with a retaining groove, the shape of which matches the outer wall of the hemispherical retaining block 43, and the outer wall of the hemispherical retaining block 43 is engaged in the retaining groove. The spring 42 has good elastic deformation capability. When the hemispherical retaining block 43 is subjected to external force, the spring 42 can undergo corresponding expansion and contraction deformation, thereby providing elastic force to the hemispherical retaining block 43, so that the hemispherical retaining block 43 can flexibly engage or disengage from the retaining groove. One end of the spring 42 is fixedly connected to the inside of the fixed retaining ring 41, and the other end of the spring 42 is fixedly connected to the rear wall of the hemispherical retaining block 43. The inner wall of the fixed retaining ring 41 is fixedly connected to the outer wall of the piston element 5. In use, the piston element 5 is securely installed inside the outer shell 1 by the limiting component 4. Under the elastic force of the spring 42, the hemispherical locking block 43 in the limiting component 4 is tightly locked in the slot on the inner wall of the outer shell 1, forming a reliable limiting fixation, ensuring that the piston element 5 will not be displaced under hydraulic action, and ensuring the normal operation of the hydraulic valve.

[0020] Working principle: During use, the piston element 5 is securely installed inside the housing 1 by the limiting assembly 4. The hemispherical locking block 43 in the limiting assembly 4 is tightly engaged in the groove on the inner wall of the housing 1 under the elastic force of the spring 42, forming a reliable limiting fixation. This ensures that the piston element 5 will not shift under hydraulic pressure, guaranteeing the normal operation of the hydraulic valve. When maintenance or repair is required, quick disassembly and assembly can be achieved by removing the assembly 3. During disassembly, unscrew the bolts 32 connecting the first mounting plate 31 and the second mounting plate 34 to separate the outer wall element 2 from the housing 1; simultaneously, remove the screws securing the mounting disc 33 to the housing 1, releasing the mounting disc 33 from the piston element 5. At this time, pulling the piston element 5 outward will cause the groove on the inner wall of the outer casing 1 to compress the hemispherical locking block 43, causing the spring 42 to contract and the hemispherical locking block 43 to disengage from the groove, thus easily removing the piston element 5 from the outer casing 1 and completing the disassembly process. This facilitates the maintenance or replacement of internal components. After maintenance, simply reinsert the piston element 5 into the outer casing 1, and the hemispherical locking block 43 will automatically engage in the groove under the action of the spring 42 to achieve the limit. Then, by using bolts 32 and screws to re-fix each part of the disassembled assembly 3, the assembly of the hydraulic valve can be completed and its normal working state restored.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
