[0022] The following is combined with Figure 1-4 The utility model is further described in detail.

[0023] Example 1, refer to Figure 1-4In order to solve the problems of the prior art in that it is inconvenient to clean, the direction of the liquid outlet cannot be adjusted according to actual needs, and the liquid flow rate of the liquid outlet cannot be controlled, this embodiment is provided. The utility model discloses an adjustable hydraulic valve, including a main valve body 3, the top of the main valve body 3 is connected to the adjusting column 1, the upper end of the adjusting column 1 is a control structure 12, a control ring 11 is fixed between the two, the control ring 11 is connected to the valve core 17 inside the adjusting column 1, the left side of the main valve body 3 is connected to the second side valve body 2 through the second fixing ring 6, a fourth side valve body 13 is fixedly installed above the second fixing ring 6, the right side of the main valve body 3 is connected to the first side valve body 4 through the first fixing ring 5, a third side valve body 9 is fixedly installed above the first fixing ring 5, and a push plate 15 is installed on the outer side of the third side valve body 9 and the fourth side valve body 13, the push plate 15 is liftable and adapted to the rubber blocks on the inner sides of the first fixing ring 5 and the second fixing ring 6, the first fixing ring 5 and the second fixing ring 6 are detachable, and the first fixing ring 5 and the second fixing ring 6 are spirally connected to the first side valve body 4, the second side valve body 2 and the main valve body 3 through an internal rubber spiral ring 20.

[0024] The internal liquid is diverted or intercepted by raising and lowering the push plate 15, thereby controlling the flow rate of the liquid at different liquid outlets. The first fixing ring 5 and the second fixing ring 6 are detachable, that is, the third side valve body 9 and the fourth side valve body 13 can change the flow direction by the installation position of the fixing ring, thereby meeting the liquid outlet requirements in different directions. Moreover, because the device is detachable, it is more convenient to clean.

[0025] There is a fixing block 19 above the push plate 15, which is adapted to the fixing grooves on the outer sides of the third side valve body 9 and the fourth side valve body 13. There is a sealing plate 21 at the bottom of the push plate 15, which is adapted to the inside of the first fixing ring 5, the second fixing ring 6 and the openings of the third side valve body 9 and the fourth side valve body 13.

[0026] The position of the push plate 15 is controlled by the position of the fixed block 19 and the fixed groove to ensure that the push plate 15 will not fall due to the flow of liquid inside the liquid. The setting of the blocking plate 21 can control whether the third side valve body 9 and the fourth side valve body 13 are enabled through the push plate 15.

[0027] The first side valve body 4 , the second side valve body 2 , the third side valve body 9 and the fourth side valve body 13 are respectively connected to the first connecting port 8 , the second connecting port 7 , the third connecting port 10 and the fourth connecting port 14 with filter screens installed thereon.

[0028] The first connection port 8, the second connection port 7, the third connection port 10 and the fourth connection port 14 provided with a filter screen prevent impurities from entering the liquid of the adjustable hydraulic valve, which may affect the service life of the device, and the accumulation of impurities is also inconvenient for subsequent cleaning.

[0029] The outer ring of the control structure 12 is a telescopic structure with scale lines on the side. The inside is a non-retractable spiral rod 16, which is connected to the valve core 17. A blocking block 18 is provided on one side of the bottom of the valve core 17. A telescopic column 22 is provided inside the main valve body 3. The telescopic column 22 and the valve core 17 are on the same vertical line. A chassis 28 is provided above the telescopic column 22. The chassis 28 is respectively provided with a first fixed block 23, a second fixed block 25, and a third fixed block 29. There is a third notch 27 between the third fixed block 29 and the second fixed block 25, and a second notch 26 between the third fixed block 29 and the second fixed block 25. There is a first notch 24 between the first fixed block 23 and the second fixed block 25. The first notch 24, the second notch 26 and the third notch 27 are adapted to the blocking block 18. The first notch 24, the second notch 26 and the third notch 27 are interconnected. The first fixed block 23, the second fixed block 25, and the third fixed block 29 are telescopic blocks connected to the top of the main valve body 3.

[0030] By controlling the extension and retraction of the structure 12 , the spiral rod 16 drives the valve core 17 to move up and down, and the gap where the blocking block 18 is located can be adjusted according to demand to regulate the flow direction of the liquid inside the liquid valve.

[0031] Specific implementation principle: When using the present invention, first select the liquid inlet and liquid outlet according to needs. If the liquid inlet and liquid outlet are on the left and right sides, rotate the control ring 11 so that the valve core 17 drives the blocking block 18 to rotate. When the blocking block 18 is above the first notch 24, the control structure 12 is compressed, the spiral rod 16 drives the valve core 17, the valve core 17 drives the blocking block 18, the blocking block 18 drives the chassis 28, and the chassis 28 drives the telescopic column 22 to be compressed downward. By observing the scale lines on the side of the control structure 12, the size of the left and right openings can be known, and the flow rate can be controlled. If liquid needs to be passed from the top or bottom, the distance between the push plate 15 and the third side valve body 9 or the fourth side valve body 13 can be adjusted. The position of the last circle of rubber spiral ring 20 can be controlled to adapt to more usage scenarios according to actual needs. If left and right liquid circulation is not required, the blocking block 18 can be placed in the second notch 26, the third notch 27, or the push plate 15 is completely placed at the bottom to perform interception and reversing processing.

[0032] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
