The end where the end cover 8 is located is defined as the outlet end of the check valve, and the open end is the inlet end of the check valve, and fluid (oil, gas and the like) flows in from the inlet end and flows out from the outlet end.
The valve cavity of the valve body 1 is internally provided with a valve core 4 which axially penetrates through, one end of the valve core 4 is fixed at the center of the end cover 8, and the other end of the valve core 4 extends to the port of the opening end of the valve body 1. The valve core 4 is sleeved with a valve plate 6 which moves along the valve core 4. A spring 7 is arranged between the valve plate 6 and the end cover 8. The center department of the opposite face at valve block 6 or/and end cover 8 has seted up the recess, can wholly arrange the recess in after the spring 7 compression to guarantee that valve block 6 can remove 8 departments of end cover and laminate with it, and shelter from the normal through-hole 9 on the end cover 8 after the laminating.

Simultaneously, after the valve plate 6 is attached to the check ring 2, the check ring 2 seals the circumference of the valve plate 6, and the reverse circulation of fluid is avoided.
With reference to fig. 2 to 3, a circulation groove 3 and a throttling groove 5 are formed in the inner wall of the valve body 1, the circulation groove 3 and the throttling groove 5 are both formed along the axial direction of the valve body 1, the circulation groove 3 is located on one side of an inlet of the valve body 1, and the throttling groove 5 is located on one side of an outlet of the valve body 1. The circulation groove 3 is annularly arranged along the circumference of the inner wall of the valve body 1, a plurality of throttling grooves 5 are uniformly arranged on the valve body 1 at intervals, the circulation groove 3 is communicated with the throttling grooves 5 end to end, and the joint of the circulation groove 3 and the throttling grooves 5 is positioned in the middle of the valve cavity.
The specific working process and working principle are as follows:
The valve with adjustable throttling amount of fluid is arranged in a pipeline where the fluid flows, and in a normal state or when the fluid flows reversely, the valve plate 6 is attached to the retainer ring 2 to seal the inlet end of the one-way valve, so that the one-way valve is sealed, as shown in fig. 8.
When the fluid has a forward flow, the pressure of the fluid acts on the valve plate 6 and pushes the valve plate 6 away from the retainer ring 2, and the flow rate of the fluid is gradually increased in the process that the valve plate 6 gradually leaves the retainer ring 2, see section S1 in fig. 9, when the valve plate 6 and the valve plate 2 are located between the retainer ring 2 and the end cover 8, the fluid is in the maximum flow state, see section S2 in fig. 9, if the pressure of the fluid is not continuously increased, the valve plate 6 will be always located between the retainer ring 2 and the end cover 8, and at this time, the maximum flow state of the fluid is maintained, as shown in fig. 4. In the maximum flow state, fluid passes through the valve plate 6 through the flow groove 3 after entering the valve cavity and then flows out of the valve cavity through the normal through hole 9 and the throttling groove 5 on the outer ring of the end cover 8, the flow capacities of the fluid at the flow groove 3 and the fluid at the end cover 8 (including the sum of the normal through hole 9 and the throttling groove 5 on the outer ring of the end cover 8) are respectively larger than the flow capacity of the fluid at the inlet end, and therefore the flow groove 3 and the end cover 8 cannot generate throttling effects in the maximum flow state of the fluid.
As shown in fig. 5 to 6, when the pressure of the fluid continues to increase, the valve plate 6 gradually moves to the joint of the flow groove 3 and the throttle groove 5, at this time, the fluid entering the valve cavity can only pass through the valve plate 6 through the throttle groove 5 on the outer ring of the valve plate 6 and flows out through the end cover 8, and with the increasing of the fluid pressure, the valve plate 6 gradually enters the range of the throttle groove 5, with the continuous entering of the valve plate 6 into the range of the throttle groove 5, the overlapping length of the outer ring of the valve plate 6 and the throttle groove 5 continuously increases, so that the length of the throttle groove 5 through which the fluid needs to pass through the valve plate 6 continuously increases, the flow rate of the fluid continuously decreases, see section S3 in fig. 9, after the whole valve plate 6 enters the range of the throttle groove 5, the valve plate 6 realizes the first throttling of the fluid, and if the pressure of the fluid is not continuously increasing, the whole valve plate 6 is located between the, at this time, the flow rate of the fluid is stabilized at a certain value, see section S4 in fig. 9. From the above, by setting the thickness of the valve sheet 6, the length of the flow passage throttled for the first time by the valve sheet 6 can be set.
As shown in fig. 7, when the pressure of the fluid continues to increase, the valve sheet 6 moves to the end cover 8 and is attached to the end cover 8, and the valve sheet 6 shields the normally through hole 9 in the end cover 8 after being attached to the end cover 8. At this time, the length of the throttling channel is the superposition of the thicknesses of the valve plate 6 and the end cover 8, so that the valve plate 6 and the end cover 8 are combined to realize secondary throttling of the fluid, the degree of throttling realizes superposition, and at this time, the minimum flow state of the check valve is shown in the section S5 of fig. 9.
In the check valve, the setting of primary throttling of the fluid can be accurately obtained by designing the flow passing through the valve plate 6 and the flow passing through the end cover 8 in unit time, and the setting of the length of the throttling channel in secondary throttling can be realized by designing the thicknesses of the valve plate 6 and the end cover 8, so that the accurate control of the fluid flow is realized.

This example differs from example 1 in that: in the present embodiment, the spring 7 is implemented by a tower spring or other elastic mechanism, such as a plurality of spring sleeves with different elastic coefficients.
The present valve with adjustable restriction of the fluid may be any combination of the above embodiments.
Example 4:
This example differs from example 1 in that: in the present embodiment, the circulation groove 3 and the throttle groove 5 are both provided in the valve body 4.
Example 5:
this example differs from example 1 in that: as shown in fig. 11, in the present embodiment, the valve plate 6 is also provided with a constant through hole, so that the valve in the present embodiment can realize fluid flow in reverse direction, but cannot realize throttling effect when the fluid flows in reverse direction.
example 6:
This example differs from example 1 in that: as shown in fig. 12, in the present embodiment, two valve cavities are respectively disposed on two sides of the end cover 8, and the two valve cavities, the flow groove 3 and the throttle groove 5 disposed in the valve cavities are symmetrically formed, so that the valve of the present embodiment can realize the flow of fluid in two directions, and realize the superposition of the throttling effects in two directions.
