Embodiment 5
Referring to Fig. 3, Fig. 4, Fig. 5, the control valve of the present embodiment, unlike foregoing embodiments：Valve performs machine
Structure includes Electronic control part, and the Electronic control part is by 2 motors（Not shown in figure）, sector gear 6, rack 7 and cone
Shape individual gears 8 form；Motor is fixedly connected with valve body 1, and rack 7 is fixedly connected with spool；One motor and sector gear 6 are driven
Connection, the sector gear 6 and rack 7 coordinate linkage, another motor and taper individual gears 8 are sequentially connected, the taper list
Gear 8 and rack 7 coordinate linkage；The motor connects power supply by controlling switch.
The effect of sector gear is mainly by pinion rack come Open valve；The effect of taper individual gears mainly works as valve
When door needs to close, circular card groove body is caught on by hook, it is necessary to taper individual gears down " are stirred " at this time, can just decontrol hook
Circular card groove body, and under the pulling force of tensioning spring, realize that valve closes（Reset）.
The control valve of the present embodiment forms for mechanical control part and Electronic control part two parts, wherein mechanical part
Can complete independently valve opening and closing action, powered part complete valve opening and closing action need mechanical part to participate in
Coordinate, could complete.Mechanical part forms：Valve body handle, spool, spring, circulation card slot, hook, fixed rack and reducing gear
Wheel group.Wherein spool, spring, circulation card slot and hook are the main device of valve mechanical control part, fixed rack and deceleration
Gear set is the slave part of mechanical control part, plays the role of reducing friction and deceleration buffer.
The utility model control valve is manually operated principles illustrated：
Valve reset condition is closing（Spring is in contraction state, is subject to the pulling force of spring, spool closing valve at this time）.
When operation handle 11 is depressed, spool moves down, and drives circular card groove body to move down, spring elongation, at this time hook
It is mobile along " sliding rail " in circulation card slot（Sliding trace is shown in that Fig. 6 circulates card slot sliding trace figure）." sliding rail " table
Face is as needed, is designed as scraggly height, to control being slided along sliding trace circulating repetition for hook（A → B
→ C → D → E → F → A）.
When hook is moved to card slot peak H, limited be subject to card slot, operation handle 11 can not be pressed down, operation
Personnel decontrol operation handle 11, and hook, which is taken advantage of a situation, at this time catches on G points, controls spool to remain stationary as, and valve is opened.It is hooked in groove
Slided according to track：A → B → C → D → H → G；
When operation handle 11 is " again " depressed, circular card groove body moves down, and is hooked in circulation card slot along " slip
Track " moves up a bit, is limited be subject to card slot I points, and operation handle 11 can not be pressed down, and operating personnel unclamp manipulator
Handle 11, circular card groove body are subject to spring tension, move up, and hook is along straight channel sliding on the right side of " sliding rail ", and spool is on the whole
Move, block valve, valve is closed, sliding trace：G → E → F → A.
The utility model control valve electric operating principles illustrated：
When controlling " opening " valve signal, motor drives sector gear rotation（360 degree）And it is intermeshed with rack, valve
Core/piston moves down, and drives circulation card slot to move down, and when sector gear and rack are not engaged mutually, hook is just moved at this time
Card slot peak H, circulation card slot move up a bit, and hook, which is taken advantage of a situation, catches on G points, controls spool to remain stationary as, and valve is opened at this time.
When controlling " closing " valve signal, the taper individual gears installed in valve body lower portion rotate, and are engaged with spool rack, immediately phase
Mutually disengage, circulation card slot moves down a bit of（Pressed equivalent to human hand）, it is subject to spring tension, circulation card slot moves up,
Hook is integrally moved up along straight channel sliding on the right side of " sliding rail ", spool, blocks valve, sliding trace：G → E → F →
A。
The fan-shaped arc length of sector gear reference circle is approximately equal to the length of rack, sector gear 6 and taper individual gears
Reference circle and 7 reticule of rack are tangent.When sector gear and taper individual gears rotate, 360 degree are rotated clockwise every time once.
To ensure that sector gear and taper individual gears return to home position, sector gear and the toothless part of taper individual gears are opposite at this time
Rack, such design ensures sector gear and the discord rack engagement of taper individual gears toothed portion, when avoiding mechanically actuated
Sector gear and taper monodentate wheel and rack intermeshing interference problem.It is specifically shown in Fig. 4, Fig. 5 control valve closure, open mode knot
Structure schematic diagram（The left side is mechanical part epidemic situation comparison）
When sector gear 6 rotates clockwise simultaneously and rack 7 is intermeshed, spool/piston moves down, mechanical control part
Hook catches on circular card groove body, and valve is opened.When needing electronic closing valve, taper individual gears 8 are used.Beaten since valve is in
Open state, at this time spool be located at valve body lower portion, taper individual gears are rotated by 360 °, with spool rack engaged transmission, Mechanical course portion
The hook divided, which is taken advantage of a situation, is rocked to the circular card groove body rightmost side, and spool/piston is subject to the spring tension of mechanical control part, and is subtracting
Moved upwards under the action of fast gear set, realize that valve is closed.
Due to reasons such as power-off or manual operations, when using Electromechanical Control, valve sealed condition may be indefinite.Therefore
In routine use, taper individual gears can be as the Reset device of valve spool of valve.I.e. in each start, control program is equal
Taper individual gears are made to rotate clockwise 360 degree, to ensure that valve is closed.Concrete principle is as follows：Start front valve core has
Two states, when valve is closed, 7, spool tooth is located at valve body top, the rotation emptying of taper individual gears at this time；When valve is opened,
Spool rack is located at valve body lower portion at this time, and taper individual gears 8 rotate, and with the engaged transmission of spool rack 7, realize that valve is closed.
