[0001] This utility model relates to the field of multi-way valve technology, and in particular to a hydraulic multi-way valve assembly. Background Technology
[0002] A hydraulic multi-way valve assembly is a device that controls the direction and flow rate of hydraulic fluid through multiple valves. Hydraulic multi-way valve assemblies typically have functions such as reversing, regulating flow and pressure, and can be flexibly configured according to requirements. They are widely used in hydraulic systems to achieve independent control and coordinated operation of multiple actuators.
[0003] However, existing hydraulic multi-way valve assemblies have shortcomings. First, existing hydraulic multi-way valve assemblies are often installed and fixed using fasteners such as bolts, which requires tools for disassembly, making operation cumbersome and inconvenient for maintenance and replacement. Second, existing hydraulic multi-way valves lack auxiliary cooling structures for hydraulic oil, resulting in high hydraulic oil temperatures during return flow, which leads to a decline in oil performance. Therefore, a new hydraulic multi-way valve assembly is proposed to solve the above problems. Utility Model Content

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.
[0030] Reference Figures 1-3 This utility model provides an embodiment of a hydraulic multi-way valve assembly, including a multi-way valve body 1 and a cartridge seat 3. A cartridge block 2 is fixedly connected to the bottom end of the multi-way valve body 1, and the cartridge block 2 is inserted into the inner wall of the cartridge seat 3, allowing the multi-way valve body 1 to be mounted on the cartridge seat 3. Connecting grooves 4 are provided on both sides of the inner wall of the cartridge seat 3. Spring pieces 5 are fixedly connected to one side of the inner wall of each of the two connecting grooves 4. A retaining plate 6 is fixedly connected to one end of each of the two spring pieces 5. Under the action of elastic force, the spring pieces 5 can push the retaining plate 6 out of the groove. A sloping groove 8 is provided on the front side of the retaining plate 6 to facilitate pressing the retaining plate 6. The cartridge block 2 is movable, and slots 7 are provided on both sides. A through hole 10 is provided on one side of the inner wall of the two connecting slots 4. A pusher 9 is inserted and connected to the inner wall of the two through holes 10. The cartridge block 2 is unlocked by pushing the pusher 9. A locking component is installed on one side of the pusher 9 to lock the position of the pusher 9. A strip plate 14 is fixedly connected to one end of the front side of the multi-way valve body 1. A heat dissipation component is installed on one side of the cartridge seat 3 to assist in the heat dissipation of the hydraulic oil and avoid the performance degradation caused by excessive oil temperature. A return oil hole 19 is provided on one side inside the cartridge seat 3 for the return of hydraulic oil.
[0031] Reference Figure 2A lock hole 15 is provided at one end of the strip 14. The locking assembly includes a groove 11, a spring 12 and a locking block 13. The groove 11 is provided on one side of the pusher 9. The inner wall of the groove 11 is fixedly connected to the spring 12. One end of the spring 12 is fixedly connected to the locking block 13. Under the action of the spring force of the spring 12, the locking block 13 will be pushed out of the groove 11.
[0032] Reference Figure 2 One end of the locking block 13 engages with the inner wall of the lock hole 15, which can lock the position of the pusher 9 so that it cannot be pressed and prevents accidental operation.
[0033] Reference Figure 2 One end of the card plate 6 engages with the inner wall of the card slot 7, which can lock the position of the insert block 2, thereby fixing the position of the multi-way valve body 1 above.
[0034] Reference Figure 3 and Figure 4 The heat dissipation component includes a bracket 17, a fan 18, and a temperature control switch 20. The bracket 17 is fixedly connected to the top of one side of the multi-way valve body 1. The fan 18 is fixedly installed on the top of the inner wall of the bracket 17. The bottom of the fan 18 is directly facing the return oil pipe connected to the hydraulic multi-way valve. After starting, it blows air into the return oil pipe connected below, which can play an auxiliary role in heat dissipation of the hydraulic oil in the pipe. The temperature control switch 20 is fixedly embedded in the inner wall of the return oil hole 19 and can detect the temperature of the hydraulic oil flowing through it.
[0035] Reference Figure 3 and Figure 4 The fan 18 is electrically connected to an external power supply via a temperature control switch 20. When the temperature control switch 20 detects that the temperature of the hydraulic oil during the return flow is higher than the set value, it will automatically control the fan 18 to start for auxiliary heat dissipation.
[0036] Reference Figure 1 and Figure 4 The top of the bracket 17 is made open to the input end of the fan 18, so that the input end of the fan 18 can guide the air above to the output end and blow it out to assist in cooling the hydraulic oil.
[0037] Reference Figure 1 Lugs 16 are fixedly connected to the bottom of both sides of the multi-way valve body 1. Fasteners can be used at the lugs 16 to fix the hydraulic multi-way valve in a designated position.
[0038] Working principle: The hydraulic multi-way valve assembly is fixed by fasteners at the lug 16 of the insert 3. By pressing the locking block 13 at the end of the strip 14, the spring force of the spring 12 is overcome and it is pressed back into the groove 11. At this time, the lock is released and the pusher 9 can be pressed again. With the cooperation of the inclined groove 8, the two side plates 6 can be squeezed back into the connecting groove 4, thereby releasing the lock on the insert 2 and removing the multi-way valve body 1. No tools are needed, which is convenient and quick, and facilitates the maintenance and replacement of the multi-way valve body 1. The blower 18 is directly below the return oil pipe connected to the hydraulic multi-way valve. A temperature control switch 20, model KSD301, is installed in the return oil hole 19 of the hydraulic multi-way valve. When it detects that the temperature of the hydraulic oil during the return flow is higher than the set value, it will automatically control the blower 18 to start blowing air into the return oil pipe connected below, which can play a role in heat dissipation of the hydraulic oil in the pipe and prevent the performance from being reduced due to high oil temperature.
