Description

Technical Field

[0001] This utility model belongs to the field of hydraulic valve technology, specifically referring to an assembled hydraulic valve. Background Technology

[0002] Hydraulic valves are key components in hydraulic systems, used to control the flow direction, pressure, and flow rate of fluids. Check valves, a type of hydraulic valve, are primarily used to prevent backflow and ensure unidirectional flow within the system. Traditional check valves typically consist of a valve body, a valve core, and a spring; the valve core opens and closes under the action of the spring.

[0003] The valve core and spring of a check valve will wear out after long-term use, but the valve core and spring of a traditional check valve are inconvenient to assemble and disassemble, which increases maintenance costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that the valve core and spring of traditional one-way valves are inconvenient to assemble and disassemble, which increases maintenance costs.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: an assembled hydraulic valve, including a valve body and a valve core, a limiting ring is provided at one end of the inner sidewall of the valve body, a stop seat is detachably provided at the other end of the inner sidewall of the valve body, the valve core is slidably disposed in the valve body and between the limiting ring and the stop seat, a drain port is provided at the center of the stop seat, a through hole is provided on the valve core, a spring is provided between the stop seat and the valve core, and the valve core blocks the limiting ring under the elastic force of the spring.

[0006] Preferably, the side wall of the stop is provided with an extension sleeve, the end of the extension sleeve is provided with a gasket, the end of the valve body near the gasket is provided with a connecting ring, and both the gasket and the connecting ring are provided with through holes.

[0007] Preferably, the end of the valve core near the limiting ring is configured as a frustum, the end of the valve core away from the limiting ring is configured as an open hollow cavity, and the end of the spring is located on the side wall inside the valve core.

[0008] Preferably, the inner wall of the valve core is slidably tangential to the valve body, the inner wall of the valve body is provided with a groove, and the through hole on the valve core moves within the length of the groove.

[0009] Preferably, the valve body has a bent ring at the end near the limiting ring, and the bent ring has a positioning hole.

[0010] The beneficial effects achieved by adopting the above-described structure are as follows:

[0011] 1. The stop seat of this assembled hydraulic valve adopts a detachable design and is fixed by through holes on the washer and connecting ring. When the valve core, spring and other internal components malfunction, the stop seat can be easily removed by simply removing the fixing parts of the connecting washer and connecting ring, and then the internal components (valve core and spring) can be repaired or replaced. Disassembly is convenient and maintenance efficiency is improved.

[0012] 2. The end of the valve core near the limit ring is designed as a frustum structure, which can fit tightly with the limit ring. Under the elastic force of the spring, it can effectively seal the limit ring, forming a good sealing effect and reducing oil leakage. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, this utility model proposes an assembled hydraulic valve, including a valve body 1 and a valve core 2. One end of the inner wall of the valve body 1 is provided with a limiting ring 3, and the end of the valve body 1 near the limiting ring 3 is provided with a bending ring 13. The bending ring 13 is provided with a positioning hole 14. The other end of the inner wall of the valve body 1 is detachably provided with a stop seat 4. The valve core 2 is slidably disposed in the valve body 1 and is located between the limiting ring 3 and the stop seat 4. The center of the stop seat 4 is provided with a drain port 5. The valve core 2 is provided with a through hole 6. A spring 7 is provided between the stop seat 4 and the valve core 2. The valve core 2 blocks the limiting ring 3 under the elastic force of the spring 7 and is fixed by a washer 9 and a connecting ring 10 through a through hole 11. When the internal components such as the valve core 2 and the spring 7 malfunction, the stop seat 4 can be easily removed by simply removing the fixing parts of the connecting washer 9 and the connecting ring 10, so that the valve core 2 and the spring 7 can be repaired or replaced. Disassembly is convenient and maintenance efficiency is improved.

[0021] like Figure 3 As shown, the side wall of the stop seat 4 is provided with an extension sleeve 8, the end of the extension sleeve 8 is provided with a washer 9, and the end of the valve body 1 near the washer 9 is provided with a connecting ring 10. Both the washer 9 and the connecting ring 10 are provided with through holes 11. The washer 9 and the connecting ring 10 are fixed together through the through holes 11 to position the stop seat 4.

[0022] like Figure 2 As shown, the end of the valve core 2 near the limiting ring 3 is configured as a frustum, and the end of the valve core 2 away from the limiting ring 3 is configured as an open hollow cavity. The end of the spring 7 is located on the side wall inside the valve core 2.

[0023] like Figure 2 As shown, the inner wall of the valve core 2 is slidably tangential to the valve body 1. The inner wall of the valve body 1 is provided with a groove 12. The through hole 6 on the valve core 2 moves within the length of the groove 12. This design makes the liquid inlet smoother. Furthermore, during the movement of the valve core 2, the cooperation between the through hole 6 and the groove 12 can precisely control the flow rate and timing of the liquid inlet, thereby improving the control accuracy of the hydraulic valve.

[0024] In practical use, first, place the valve core 2 into the valve body 1, ensuring that the valve core 2 is located between the limit ring 3 and the stop seat 4, and that the inner wall of the valve core 2 is tangentially sliding with the valve body 1. Then, place one end of the spring 7 into the inner wall of the valve core 2, and the other end of the spring 7 abuts against the stop seat 4. Next, align the extension sleeve 8 of the stop seat 4 with the end of the valve body 1, so that the washer 9 fits against the connecting ring 10. Use bolts to fix the washer 9 and the connecting ring 10 together through the through hole 11, thereby completing the installation of the stop seat 4. Finally, according to the actual installation requirements, using the positioning hole 14 on the bending ring 13, the through hole 11 on the washer 9 and the connecting ring 10, and the external flange, the hydraulic valve can be installed in the designated position, and the inlet and outlet pipelines can be connected.

[0025] When hydraulic fluid enters the valve body 1 through the inlet, the fluid pressure acts on the valve core 2. If the fluid pressure is sufficient to overcome the spring force of the spring 7, the valve core 2 will move away from the limit ring 3. At this time, the through hole 6 on the valve core 2 is aligned with the groove 12 on the inner wall of the valve body 1. The fluid enters the cavity between the valve core 2 and the stop seat 4 through the through hole 6 and the groove 12, and flows out from the drain port 5 at the center of the stop seat 4, thus achieving forward conduction. When the fluid attempts to flow in the reverse direction, the reverse fluid pressure and the spring force work together to make the valve core 2 tightly seal the limit ring 3, preventing the fluid from flowing in the reverse direction, thereby realizing the function of a check valve.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
