Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

The utility model discloses a governing valve for controlling transfusion system velocity of flow, this governing valve mainly includes from last first casing 10 to down, second casing 20 and third casing 30, as shown in fig. 2, 3 and 4, set up speed adjusting disk 21 on this second casing 20, set up circulation dish 31 on the third casing 30, wherein set up speed governing hole 22 on the speed adjusting disk 21, set up opening 32 on the circulation dish 31, second casing 20 can be relative first casing 10 and second casing 20 rotate, the relative rotation through control second casing 20 comes opening 32's flow, specifically be through the coincidence area between opening 32 on changing speed adjusting disk 21 on speed adjusting hole 22 and the circulation dish 31.

How to adjust the flow is further explained in detail: the speed regulation hole 22 and the flow hole 32 in this embodiment have the same structure, and are both elliptical, for example: when the speed adjusting hole 22 on the speed adjusting disk 21 and the flow hole 32 on the flow disc 31 are perpendicular to each other, the drop speed is 20 drops at the time, as shown in fig. 5, when the speed adjusting disk 21 is rotated to make the speed adjusting hole 22 and the flow hole 32 staggered at a certain included angle, as shown in fig. 6, the drop speed is 40 drops at the time, when the speed adjusting disk 21 is continuously rotated to further enlarge the included angle between the speed adjusting hole 22 and the flow hole 32, as shown in fig. 7, the drop speed is 60 drops at the time, when the speed adjusting disk 21 is continuously rotated to further enlarge the included angle between the speed adjusting hole 22 and the flow hole 32, as shown in fig. 8, the drop speed is 80 drops at the time, when the speed adjusting disk 21 is continuously rotated to make the speed adjusting hole 22 and the flow hole 32 completely coincide, at the time, the drop speed is unlimited, and is the maximum drop speed, as shown in fig. 9.
