Conversely, if the fluid flows reversely into the tesla valve, the fluid is divided into two paths at the first junction and is converged again at the second junction, except that the flow directions of the two paths of fluid are opposite, so that a great resistance is formed, and therefore, the tesla valve can only pass forward and is difficult to reverse flow.
The bypass flow passage in the Tesla valve is closely related to the reverse flow resistance, and no movable mechanical component exists in the Tesla valve, so that the opening and closing states and the opening and closing degree of the bypass flow passage cannot be adjusted, and further the resistance of fluid in the Tesla valve in the reverse flow cannot be adjusted, and therefore, if the Tesla valve is used in the use situation of needing to adjust the reverse flow resistance of the Tesla valve, the application of the Tesla valve is limited.

The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1: the utility model provides an adjustable tesla valve which comprises a valve body 1 and a valve core 2.
Wherein, the two ends of the valve body 1 are respectively an inlet end 3 and an outlet end 4, and the inlet end 3 and the outlet end 4 are communicated through a main channel runner 5 for inflow and outflow of fluid.
As shown in fig. 1, two sides of the main channel 5 are provided with a plurality of groups of branch channels 6 communicated with the main channel, and the branch channels 6 comprise straight line parts and arc parts connected with the straight line parts; the straight line part and the circular arc part are communicated with the main channel 5.
Specifically, the straight portion communicates with the main flow passage 5 near the outlet end 4, and the circular arc portion communicates with the main flow passage 5 near the inlet end 3.
The above structure is a one-way flow conduction valve, and in practical application, because the fluid has inertia, the resistance received by the valve is different when the fluid passes through the valve in different directions. For fluids, the wall of the tube is not smooth, which can create resistance to its flow. A tesla valve is a one-way valve that has a fluid path designed to a specific shape to achieve the effect of increasing resistance and reducing flow rate. When fluid reversely enters the tesla valve through the outlet end 4, the fluid is split, one part flows along the main channel flow passage 5, the other part flows into the branch flow passage 6, and finally the fluid is converged with the fluid in the main channel flow passage 5 again, in the process of fluid convergence, the fluid collides with each other in different directions, so that resistance is generated on the fluid in the main channel flow passage 5, the energy of the fluid is gradually reduced along with the more split passing, and if the direction is changed, the fluid does not have too great resistance when entering from the other end, and the fluid can easily pass.
The number of the groups of the branch flow passages 6 can be set according to the actual application scenario, and the utility model is not limited.
As shown in fig. 2 and 3, on the basis of the above structure, the present utility model is further provided with a valve core 2 which is a hollow tube with two open ends and screw threads on the outer surface; and simultaneously, the main channel 5 is internally provided with threads, the threads of the valve core 2 are matched with the threads in the main channel 5, and the structure ensures that the valve core 2 can be screwed in and out of the main channel 5 of the Tesla valve.
In the utility model, the end of the valve core 2 away from the main channel 5 is provided with a handle shell 7 which is convenient to hold.
The specific specification and material of the handle housing 7 can be set according to the actual application scenario, and the present utility model is not limited.
In the present utility model, the length of the valve element 2 is equal to or less than the length of the valve body 1. The longer the length of the valve element 2 is, the more branch passages 6 the valve element can close when the tesla valve is used to reduce the resistance in the reverse direction. However, the length of the valve element 2 is also related to the distribution width of the branch flow passages in the valve body 1, and the length of the valve element 2 may be equal to or less than the length of the valve body 1 for reasons such as cost.
When the tesla valve is used, the use method is as follows:
when the resistance of the Tesla valve in the reverse flow is required to be reduced, the valve core 2 is screwed in from the Tesla valve, the number of stages of resistance flow channels required to pass through when fluid passes through the Tesla valve in the reverse direction is reduced, and the resistance of the fluid is reduced.
Specifically, when the resistance of the tesla valve in the reverse flow needs to be reduced, the valve core 2 can be screwed in from the inlet end 3 of the tesla valve, the valve core 2 is closely attached to the main channel flow channel 5, and when the position of the valve core 2 screwed in passes through the branch channel flow channel 6, the outer wall of the hollow pipe with the valve core 2 as a whole can close the branch channel flow channel 6 at the corresponding position, so that the branch channel flow channel 6 stops to split, and the resistance caused by the fluid flow of the branch channel flow channel 6 is reduced. As the valve core 2 is screwed into more parts, the number of the branch flow passages 6 closed by the valve core 2 is more and more, and thus the resistance caused by the fluid flow of the branch flow passages 6 is smaller and smaller.
Or, the valve core 2 is screwed in from the outlet end 4 of the tesla valve, the valve core 2 is closely attached to the main channel flow channel 5, when the screwed position of the valve core 2 passes through the branch channel 6, the outer wall of the hollow pipe with the valve core 2 as a whole can seal the branch channel 6 at the corresponding position, so that the branch channel 6 stops to split, and the resistance caused by the fluid flow of the branch channel 6 is further reduced. As the valve core 2 is screwed into more parts, the number of the branch flow passages 6 closed by the valve core 2 is more and more, and thus the resistance caused by the fluid flow of the branch flow passages 6 is smaller and smaller.
Accordingly, when the resistance of the tesla valve in the reverse flow is required to be increased, the valve core 2 is screwed out of the tesla valve, the number of stages of resistance flow channels required to pass through when the fluid passes through the tesla valve in the reverse direction is increased, and the resistance of the fluid is increased.
Specifically, when the resistance of the tesla valve in the reverse flow needs to be increased, the valve core 2 can be screwed out from the inlet end 3 of the tesla valve, and as the part of the valve core 2 overlapped with the main channel 5 is smaller, the number of the branch channels 6 closed by the valve core 2 is smaller, so that the resistance caused by the fluid flow of the branch channels 6 is larger.
Alternatively, the valve core 2 is screwed out from the outlet end 4 of the tesla valve, and as the overlapping part of the valve core 2 and the main channel 5 is smaller, the number of branch channels 6 closed by the valve core 2 is smaller, so that the resistance caused by the fluid flow of the branch channels 6 is larger.
In practical application, the specification size of the tesla valve and the number of stages of the resistance flow channel can be adjusted according to the application scene and the resistance adjustment range in the reverse flow so as to be better suitable for the application environment.
In conclusion, when the adjustable Tesla valve is used, the resistance of the Tesla valve in the reverse flow process can be flexibly adjusted according to actual needs; meanwhile, the adjustable Tesla valve is simple and reliable in structure and convenient to operate.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
