[0002] A one-way valve is a valve that allows fluid to flow only along the inlet, but the medium at the outlet cannot flow back. It is commonly known as a one-way valve. A one-way valve is also called a check valve or a non-return valve. It is used in hydraulic systems to prevent oil from flowing in the opposite direction, or in pneumatic systems to prevent compressed air from flowing in the opposite direction. There are two types of one-way valves: straight-through and right-angle. Straight-through one-way valves are installed on the pipeline with threaded connections, and right-angle one-way valves are available in three forms: threaded connection, plate connection, and flange connection.

[0003] However, the existing one-way valves have the following problems during use: usually one-way valves cannot adjust the flow rate, they can only achieve one-way flow and prevent fluid backflow, and some one-way valves are equipped with adjustment mechanisms, but the adjustment operation method is relatively complicated and inconvenient to adjust under high pressure and large flow conditions. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2The utility model provides a technical solution: an adjustable high-pressure and large-flow one-way valve, comprising a one-way valve body and a liquid infusion tube 1 symmetrically installed at both ends of the one-way valve body, the one-way valve body comprising a valve body 2, a guide plate 3, a guide column 4, a reset spring 5, a valve core 6 and an adjustment component, the two ends of the valve body 2 are processed and formed with two groups of cavities 7 and a cavity 2 8 is formed in the middle, the cavity 2 8 and the two groups of cavities 7 are separated by two groups of guide plates 3, the guide plate 3 is provided with a guide port 9 and A through hole 10 is opened in the middle, and the guide column 4 is horizontally inserted into the two groups of through holes 10. The reset spring 5 is embedded in the guide column 4. One end of the reset spring 5 is in contact with the right guide plate 3 and the other end is in contact with the valve core 6. The valve core 6 is fixed on the guide column 4. A liquid guiding notch 11 is formed between the valve core 6 and the inner wall of the cavity 8. The adjustment component is composed of four groups of adjustment rods 12. The four groups of adjustment rods 12 are respectively threaded on the valve body 2, and the inner ends of the adjustment rods 12 are used in conjunction with the valve core 6.

[0018] Further improvement, such as Figure 1 As shown, the valve core 6 is a disc-shaped structure as a whole and includes an inner disc 13 and a deformable outer ring 14 fixed to the outer side of the inner disc 13 . The deformable outer ring 14 is located at the liquid guiding notch 11 , and the valve core 6 is used to block the liquid guiding notch 11 .

[0019] Further improvement, such as Figure 1 As shown: the thickness of the left end of the deformable outer ring 14 is greater than that of the right end, and the surface of the deformable outer ring 14 is processed to have several groups of annular deformation grooves 15, which are distributed in a stacked manner. This design method facilitates the deformation adjustment of the deformable outer ring 14.

[0020] Further improvement, such as Figure 2 As shown: the adjustment rod 12 includes a handle 16 and a screw 17 fixed to the inner end of the handle 16, a contact ball 18 is fixed to the inner end of the screw 17, and the contact ball 18 is in contact with the deformable outer ring 14. The staff can hold the handle 16 and turn the screw 17, and the screw 17 can act on the deformable outer ring 15 through the contact ball 18 during the movement.

[0021] Specifically, four groups of adjusting rods 12 are evenly distributed on the outside of the valve body 2, and the angle between two adjacent groups of adjusting rods 12 is 90 degrees. This design method is convenient for adjusting the four groups of adjusting rods 12 and adjusting the deformation of the deformable outer ring 14, and then adjusting the specifications of the liquid guiding notch 11, so as to adjust the flow rate.

[0022] When in use: the fluid of the utility model enters the guide port 9 through the left cavity 17 of the valve body 2. Since the pressure of the fluid resists the valve core 6, the valve core 6 moves to the right side under the pressure, so that the guide notch 11 opens. At this time, the fluid enters the cavity 2 8 through the guide notch 11 and is guided out through the right cavity 17, thereby achieving the purpose of one-way guidance of the fluid. When the flow rate needs to be increased, the staff can turn the adjusting rod 12 inward, and the adjusting rod 12 moves inward and makes the contact ball 18 act on the deformed outer ring 15, so that the deformed outer ring 15 is compressed and its diameter becomes smaller. At this time, the specification of the guide notch 11 becomes larger during the movement of the valve core 6 to the right, thereby achieving the purpose of expanding the flow rate of the fluid. The operation is simple and easy to use.
