Specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figures 1 to 4, this water yield servomechanism includes：
Valve body 1, for the housing of whole tapses, which is provided with water inlet 11 and outlet 12, 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 above outlet 12 on the inwall of valve body 1, 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), drives the by the driving of servomotor
One valve element 21 moves 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；And, 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 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 changing the position of the second valve element 22
To adjust the size of the discharge via current stabilization hole 14；It includes the spacing grid 221 on the spacing inwall in 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, the wall of valve pocket 222 is interval with multiple
Connection internal ring cavity 42 and the conduction hole 224 of water chamber 45；The lower ora terminalis of valve pocket 222 has 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, thus adjusting
Aperture 14 elastic component 223 in current stabilization hole is conflicted between valve pocket 222 and the first valve element 21, and in the present embodiment, elastic component 223 is bullet
Spring, is set on valve rod 2；Form water chamber 45 between valve pocket 222 and valve rod 2.
Under no external force operative condition, valve pocket 222, in the presence of elastic component 223, is conflicted on spacing grid 221, is turned over
Side 225 and the distance between 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 moves 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
Enter internal ring cavity, then enter water chamber 45 via each conduction hole, flow out from outlet.
When hydraulic pressure increases, valve pocket is extruded by hydraulic pressure, moves downward extruding elastic component, and valve pocket moves down, and current stabilization hole is opened
Degree reduces, accordingly even when pressure increases but flow area reduces, and flow keeps constant, thus 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, and promotes and moves on valve pocket, current stabilization hole is opened
Degree increases, accordingly even when pressure is little, but flow area is big, and flow keeps constant.
