Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: control valve, comprises valve body 10, and this valve body 10 has inner chamber 11, and the left side wall of this inner chamber 11 is provided with water outlet 12, right side wall is provided with water intake 13, upper side wall is provided with valve rod 20.
Concretely, this inner chamber 11 is in cuboid or cube-shaped, and the left side of this inner chamber 11 is provided with in the left chute 111 moved towards up and down, right side is provided with right rail 112 in moving towards up and down.Sliding in this left chute 111, being provided with in left sealing plate 31, this right rail 112 slides is provided with right sealing plate 32.That is, this left sealing plate 31 and this right sealing plate 32 all can move up and down.The left surface of this left sealing plate 31 and this water outlet 12 match, the right flank of this right sealing plate 32 and this water intake 13 match.That is, this left sealing plate 31 can seal or open this water outlet 12 after moving up and down, this right sealing plate 32 can seal or open this water intake 13 after moving up and down.
The right flank of this left sealing plate 31 is provided with upper left fixture block 311 and lower-left fixture block 312, the left surface of this right sealing plate 32 is provided with upper right fixture block 321 and bottom right fixture block 322, and this upper left fixture block 311 and lower-left fixture block 312 have spacing, this upper right fixture block 321 and the bottom right fixture block 322 that length is L1 has the spacing that length is L2.Meanwhile, between this left sealing plate 31 and this right sealing plate 32, there is gap.
The lower end of this valve rod 20 is fixed with horizontal square connecting plate 40, and this connecting plate 40 has thickness D.The left side of this connecting plate 40 is stuck between this upper left fixture block 311 and lower-left fixture block 312, right side is stuck between this upper right fixture block 321 and bottom right fixture block 322, and the left side of this connecting plate 40 and this upper left fixture block 311, between lower-left the fixture block 312 and right side of this connecting plate 40 and this upper right fixture block 321, be equipped with elastic insert 41 between bottom right fixture block 322, this elastic insert 41 comprises rubber spacer 411 and is fixed on the spring steel flaggy 412 of these rubber spacer 411 both sides, and this elastic insert 41 has thickness H.And, L1 >=3 (D+H), L2=D+H.
Meanwhile, the part this valve rod 20 being positioned at this inner chamber 11 is provided with limiting stopper 21.That is, this limiting stopper 21 makes this valve rod 20 only can rise suitable height, in order to avoid this valve rod 20 and this connecting plate 40 depart from when this valve rod 20 is subject to larger upwards tractive force.The part that this valve rod 20 is positioned at the outside of this inner chamber 11 is provided with outside thread 22, and this outside thread 22 is arranged with nut 23, and this nut 23 outer rim has straight-tooth 231, and this nut 23 is stuck in the draw-in groove 24 of right openings, and this draw-in groove 24 is fixed on this valve body 10.That is, this nut 23 is that an axle center place establishes female gear, and this nut 23 is only rotatable and cannot move up and down.This valve body 10 is fixed with actuating motor 50, and this actuating motor 50 is connected with retarder 60, the output shaft of this retarder 60 is fixed with gear 70, and this gear 70 and this straight-tooth 231 engage.
Course of action of the present invention and working principle: after this actuating motor rotates, this retarder works, and this gear rotarily drives this nut and rotates.After this nut rotates, drive this valve rod to rise or decline.When this valve rod rises, first the right side of this connecting plate drives this right sealing plate to rise, thus this water intake is opened in advance, and water enters in the gap between this left sealing plate and this right sealing plate temporary.Along with the further rising of this valve rod, the left side of this connecting plate touches this upper left fixture block and then drives this left sealing plate to rise, and is then opened by this water outlet, and be temporary in water in this gap by this water outlet, this control valve is opened.Otherwise when deserving this valve rod and declining, first the right side of this connecting plate drives this right sealing plate to decline, thus this water intake is closed in advance.Along with the further decline of this valve rod, the left side of this connecting plate touches this lower-left fixture block and then drives this left sealing plate to decline, and then closed by this water outlet, this control valve ends.That is, this water intake always opens and closes prior to this water outlet, thus makes opening or ending of this control valve formation stages formula, and for directly opening or ending, the movement of this valve rod is comparatively laborsaving.And after actuating motor drive nut rotation, utilize the principle of screw-nut body, make this left sealing plate and this right sealing plate action, also reduce further the difficulty of opening and ending.
It should be noted that, through lot of experiments, select the parameters relationship of L1 >=3 (D+H), L2=D+H, this left sealing plate and right sealing plate can be made to have very appropriate unlatching opportunity, be conducive to the design difficulty reducing this control valve.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
