The liquid outlet folding control principle of proportional valve is as shown in figure 8, liquid outlet control motor 3 is fixed on the outside of valve body 1
The rectangular output shaft of lower part, liquid outlet control motor 3 stretches to the inside of valve body 1, when electric telescopic rod 4 extends completely, valve
Groove on bar 74 is just worked good with the rectangular output shaft on liquid outlet control motor 3, and liquid outlet controls motor 3 at this time
The on and off of butterfly valve is controlled, realizes the folding of proportional valve liquid outlet.
Specific work process is as follows: under original state, 24 closure of active semicircle sealing 23 and the sealing of driven semicircle, i.e. valve body
1 valve body liquid outlet 12 is in close state, and the butterfly valve built in spool 7 is in close state, and electric telescopic rod 4 is in contraction-like
State, spool 7 are located at the inner upper of valve body 1, and the valve body inlet 11 of valve body 1 connects inlet pipe, valve bottom 5 by flange-interface
Valve bottom liquid outlet 51 pass through flange-interface connect outlet tube road.It is driven firstly, inlet controls motor 2 by series of gears
Active semicircle sealing 23 and driven semicircle sealing 24 are transformed into opening state by closed state, at this point, liquid flows through valve body 1
Valve body inlet 11, valve body liquid outlet 12 enter inside proportional valve.Then, active semicircle sealing 23 and driven semicircle sealing 24 are protected
Opening state is held, electric telescopic rod 4 starts to extend, and drives coupled spool 7 to move down, as electric telescopic rod 4 is stretched
Long, spool 7 constantly moves down, and when electric telescopic rod 4 extends completely, the stem groove on valve rod 74 just controls electricity with liquid outlet
The rectangular output shaft cooperation of machine 3 is blocked, and the square groove 83 at the spool liquid outlet 72 of spool 7 is just and at valve bottom inlet 52
Bumping square 82 cooperation be sealed, at this time inlet control motor 2 control active semicircle sealing 23 and driven semicircle sealing 24
Closed state is gone to by opening state.The liquid volume that proportional valve is quantitatively discharged is exactly active semicircle sealing 23 and driven semicircle envelope
The liquid volume that this block space is contained between the top of butterfly valve built in the lower section of mouth 24 and spool 7.It is logical that liquid outlet controls motor 3
Crossing the rectangular output shaft control rotation of valve rod 74 opens butterfly valve, and the intracorporal liquid of valve can be discharged.After liquid in valve empties,
Liquid outlet controls motor 3 and controls butterfly valve closure, and electric telescopic rod 4 is shunk, and spool 7 playbacks, and restPoses.In valve body 1
Top is provided with air valve 6, is conducive to proportional valve discharge liquid and spool 7 rises playback.
Purpose for proportional valve beauty and in order to protect motor, electric pushrod not vulnerable to external world, can be by valve bottom 5
