Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 5 , a new type of hydraulic valve:

[0024] It includes: a valve body 1, a connecting seat 2 is fixedly installed on one side of the valve body 1, a docking seat 3 is movably installed on one side of the connecting seat 2, a positioning seat 4 is movably clamped inside the docking seat 3, an elastic member is fixedly installed on one side of the positioning seat 4, a limiting cover 5 is sleeved on one side of the elastic member, a driving rod 6 is fixedly installed on one side of the limiting cover 5, a first plug 7 is fixedly installed at the front end of the driving rod 6, a second plug 8 is fixedly installed in the middle of the outer surface of the driving rod 6, a threaded docking pipe 9 is fixedly installed on one side of the docking seat 3, and the threaded docking pipe 9 is threadedly connected to the inside of the connecting seat 2. Positioning pins 10 penetrate through the four circumferences of the outer surface of the connecting seat 2, and the front ends of the positioning pins 10 are inserted into the inside of the threaded docking pipe 9. An oil groove 11 is opened at the front end inside the valve body 1, and two groups of dredging grooves 12 are opened in the middle of the valve body 1;

[0025] When the device is used as a valve structure, the valve body 1 serves as the main structure of the hydraulic valve. And when it is used for liquid transportation, through the opening of the two groups of dredging grooves 12 inside the valve body 1, the openings on both sides of the dredging grooves 12 can be respectively used for outputting and inputting rollers. After injecting hydraulic oil into the inside of the oil groove 11, it can push the first plug 7 on the driving rod 6, and then drive the activities of the driving rod 6 and the second plug 8, so that the limiting cover 5 on the driving rod 6 squeezes the elastic member. The resilience of the elastic member can also assist in the reset movement of the driving rod 6, and then make the positions of the first plug 7 and the second plug 8 after sliding adjustment correspond to the discharge opening in the dredging groove 12, thereby blocking the dredging property of the front and rear openings in the dredging groove 12. On the contrary, when the hydraulic oil in the oil groove 11 is pumped out, the first plug 7 and the second plug 8 are misaligned with the outlet in the dredging groove 12, so that the dredging groove 12 can output through the opening at the misaligned position, so as to achieve the hydraulic regulation effect when the valve body 1 structure is used.

[0026] An oil inlet interface 13 is fixedly installed on the other side of the valve body 1, and an oil change pipe 14 is fitted and installed on one side of the bottom of the valve body 1. Check valves 15 are provided inside both the oil inlet interface 13 and the oil change pipe 14;

[0027] Through the settings of the oil inlet interface 13 and the oil change pipe 14, the two can cooperate with the one-way conveying rollers of the internal check valves 15 to be used for injecting and outputting hydraulic oil after being connected to external input and output devices.

[0028] The elastic member includes: a damper 16 and a limiting spring 17. A damper 16 and a limiting spring 17 are fixedly installed on one side of the positioning seat 4, and the limiting spring 17 is sleeved on the outer surface of the damper 16. The front ends of the damper 16 and the limiting spring 17 are inserted into the inside of the limiting cover 5;

[0029] The elasticity of the damper 16 and the resilience of the limit spring 17 can assist the reset movement of the driving rod 6 and coordinate with the activity adjustment of the first blocking block 7 and the second blocking block 8 .

[0030] A groove structure sunken into the inner wall of the valve body 1 is provided in the dredging groove 12 at the corresponding positions of the inlet and outlet joints 19, and the positioning seat 4, the first blocking block 7 and the second blocking block 8 are tightly slid inside the dredging groove 12, and their widths are greater than the width of the groove structure;

[0031] The groove structure is provided so that it can cooperate with the sliding of the first blocking block 7 and the second blocking block 8, so that it can be better adjusted in dislocation with the inside of the dredging groove 12.

[0032] See also Figure 2 , Figure 3 and Figure 4 :

[0033] The front and back sides of the valve body 1 are both clamped and installed with output panels 18, and the outer surface of the output panel 18 is embedded with an inlet and outlet joint 19, and the inner wall of the inlet and outlet joint 19 is fixedly installed with a butt joint 20, and the butt joint 20 is inserted into the inside of the dredging groove 12, and the inlet and outlet joints 19 on the two sets of output panels 18 are staggered and correspondingly distributed;

[0034] The installation of the device output panel 18 can make the docking pipe 20 snap into the inside of the dredging groove 12, so that the inlet and outlet joints 19 can correspond to the output and input of the dredging groove 12, and be used for the external pipeline structure to assist the in-and-out transportation work of the device.

[0035] The four sides of one side of the docking seat 3 are all threadedly connected with reinforcing bolts 21, and the front end of the reinforcing bolts 21 is threadedly connected to the inside of the positioning seat 4;

[0036] The provision of the reinforcing bolts 21 can increase the fixation of the positioning seat 4 structure, and play a certain role in pushing and positioning the positioning seat 4, assist in adjusting the position of the positioning seat 4 and the elastic member structure, and facilitate loose adjustment.

[0037] The outer surface of the output panel 18 is threadedly connected with positioning bolts 22 all around, and the front end of the positioning bolts 22 is threadedly connected to the inside of the valve body 1;

[0038] The through connection of the positioning bolts 22 can increase the convenience of disassembly and replacement of the output panel 18 and increase the flexibility of the device structure.

[0039] Working principle: By injecting sealed oil into the interior of the oil tank 11, the positions of the drive rod 6, the first plug 7, and the second plug 8 can be adjusted, and then the fluidity in the dredging groove 12 can be regulated. The docking seat 3 is conveniently disassembled, making the elastic member structure also have the characteristic of convenient installation, enabling it to assist in the sliding reset of the first plug 7 and the second plug 8, as well as disassembling and replacing elastic member structures with different elastic strengths, and then adjusting the pressure required for the internal regulation of the valve body 1, assisting in the multi-faceted use of the device.
