Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 2, a kind of spiral buck channel structure of flow controller, including valve body 11, the valve sheet
Body 11 is provided with fluid passage 12, and one end of the fluid passage 12 is provided with fluid intake, the fluid passage 12 it is another
End is provided with fluid issuing, and the fluid intake is provided with valve element 13, and the valve element 13 is provided with what is communicated with fluid passage 12
Pressure reducing mechanism 15 is provided with input pipe 14, the fluid passage 12, the pressure reducing mechanism 15 is more including what is be cascading
Individual decompression part 16；The operation principle of this buck channel structure is：Fluid (including liquids and gases) is in the feelings with larger pressure
Enter valve element 13 from input pipe 14 under condition, fluid enters in fluid passage 12 after the output of valve element 13, due to this structure setting
Pressure reducing mechanism 15, by setting pressure reducing mechanism 15, after fluid is exported from valve element 13, is connected between multiple decompression parts 16
Flowing, so that input pressure of the fluid in flow controller is reduced, to allow fluid issuing to realize more accurate control
System.
Structure for being depressured part 16, specifically, the decompression part 16 include lamellar body 161 and are arranged at lamellar body 161 1
Side is used to slowing down the helical duct 162 of Fluid pressure, and the lamellar body 161 is provided centrally with through hole 163.The through hole 163 is not only
Be conducive to carrying out multiple decompression parts 16 assembling contraposition, but also can be exported with the formation of helical duct 162, due to multiple decompressions
Part 16 is to stack gradually, so, when fluid enters first decompression part 16, now, the helical duct of first decompression part 16
162 can not substantially play antihypertensive effect, but the through hole 163 of fluid from the first decompression part 16 enters next decompression part 16,
Flowed in the helical duct 162 of the decompression part 16, and be output to from one end of helical duct 162 relative next drop
In casting die 16, circulate successively, so that fluid realizes decompression, when fluid is exported from last decompression part 16, relative to defeated
The pressure entered has been greatly reduced, and the experiment proved that, when input pressure is 1Mpa, the negative booster constituted using 10 decompression parts 16
Structure 15,0.1Mpa pressure can be detected in output end, so, and flow control can be controlled normally, will not be because of
Fluid pressure is excessive and can not accurately control.
In the technical program, one end of the helical duct 162 is communicated with through hole 163, the helical duct 162 it is another
One end is opening.Through hole 163 and opening can input for fluid, can also be exported for fluid part, and it is according to decompression part 16
Depending on actual interval order.
In the technical program, the lamellar body 161 is circular, hexagon or square.Certainly, in general, using circle
Shape piece has preferably assembling effect, and hexagon and square can also realize the purpose of decompression.
In order that the connection of valve element 13 is simpler, the valve element 13 is provided with screw thread, and valve element 13 passes through screw thread and fluid
Entrance is spirally connected.
Scheme as a further improvement, the one end of the valve element 13 stretches into formation extension 131 in fluid passage 12,
The extension 131 is provided with several sideway diversion holes 132, and the fluid of the input pipe 14 is exported from sideway diversion hole 132.
By sideway diversion hole 132, fluid can be made when entering fluid passage 12, do not impacted with the decompression formation of part 16 directly, fluid
There is larger pressure when being exported from sideway diversion hole 132, due to for sideway diversion body, so the inwall of fluid and valve body 11
Directly contact refracts to decompression part 16 again, so as to avoid first decompression part 16 of fluid damage of larger pressure.
In the technical program, the extension 131 is isosceles trapezoid, and the valve body 11 is provided with and tap hole 132
Corresponding buffer groove 121.Isosceles trapezoid formation allows bit space, when the fluid is exported from sideway diversion hole 132, with larger
Space, and the effect of buffer groove 121 be buffering and dampening fluid pressure.
In order to improve the sealing property of valve element 13 and valve body 11, the outside of the valve element 13 is additionally provided with the He of outer nut 17
O-ring seals 18, the outer nut 17 is spirally connected with valve element 13, and the O-ring seals 18 are sheathed on valve element 13 and positioned at outer spiral shell
Between mother 17 and valve body 11.O-ring seals 18 are compressed by outer nut 17, make O-ring seals 18 by valve element 13 and valve body
Sealing is realized in threaded connection between 11.
Certainly, in order that in the situation that outer nut 17 is compressed outer deformation does not occur for O-ring seals 18, the valve body
11 are provided with the accommodating position 111 for housing O-ring seals 18.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, it will change in specific embodiments and applications, this specification content should not be construed as
