Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 4, the water yield servomechanism includes：
Valve body 1, is the housing of whole tapses, which is provided with water inlet 11 and outlet 12, and water inlet 11 is arranged on valve
On the side wall of body, outlet 12 is the port of valve body；Flange 13 is provided with the top of outlet 12 on the inwall of valve body 1, it is convex
The middle part of edge 13 is provided with current stabilization hole 14；The present embodiment flange 13 is near outlet 12.
Valve rod 2, is arranged in valve body 1, connects servomotor (not shown), and by the driving of servomotor the is driven
One valve element 21 is moved up and down.
Sleeve 4, is arranged in valve body 1 and is set in outside valve rod 2, the inner chamber of valve body 1 is divided into and is connected with water inlet 11
Logical outer ring cavity 43 and the internal ring cavity 42 being connected with outlet 12；Multiple connection internal ring cavitys are interval with sleeve 4
42 and the water hole 44 of outer ring cavity 43；Also, each water hole 44 is respectively positioned on the top of water inlet 11.
First valve element 21, is arranged on the lower end part of valve rod 2, for closing outlet 12；First valve element 21 can basis
Need from it is of the prior art any one.
Second valve element 22, is connected on valve rod 2, positioned at the top of the first valve element, by the position for changing the second valve element 22
To adjust the size of the discharge via current stabilization hole 14；It includes the spacing spacing grid 221 on the inwall of sleeve 4, spacing
The lower section of grid 221 is provided with valve pocket 222, valve pocket 222 is slidably located on valve rod 2, is interval with the wall of valve pocket 222 multiple
The conduction hole 224 of connection internal ring cavity 42 and water chamber 45；The lower ora terminalis of valve pocket 222 is with the evagination being adapted with flange 13
Flange 225.In the presence of hydraulic pressure and elastic component 223, the distance between flange 225 and flange 13 change, so as to adjust
The aperture elastic component 223 in current stabilization hole 14 is contradicted between the valve element 21 of valve pocket 222 and first, and elastic component 223 is bullet in the present embodiment
Spring, is set on valve rod 2；Water chamber 45 is formed between valve pocket 222 and valve rod 2.
Under without external force operative condition, valve pocket 222 is contradicted on spacing grid 221 in the presence of elastic component 223, is turned over
The distance between side 225 and flange 13 maximum, in other words, the aperture in current stabilization hole 14 is maximum.
During work, servomotor drives valve rod to rotate forward, and drives and moved on the first valve element, opens outlet；Move on first valve element,
Elastic component is squeezed, and current stabilization hole remains in maximum opening state；Current enter outer ring cavity from water inlet, via each water hole
Into internal ring cavity, then water chamber 45 is entered via each conduction hole, flowed out from outlet.
When hydraulic pressure increases, valve pocket is extruded by hydraulic pressure, moves downward extruding elastic component, and valve pocket is moved down, and current stabilization hole is opened
Degree reduces, accordingly even when pressure is increased but flow area is reduced, and flow keeps constant, so as to the water outlet of constant outlet
Flow；Conversely, when hydraulic pressure reduces, the power being applied on valve pocket reduces, and elastic component is upheld, promote and moved on valve pocket, current stabilization hole is opened
Degree increase, accordingly even when pressure is little, but flow area is big, and flow keeps constant.
