Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: control valve, comprise valve body 10, this valve body 10 has inner chamber 11, and the left side wall of this inner chamber 11 is provided with that water outlet 12, right side wall are provided with water intake 13, upper side wall is provided with valve rod 20.
Concretely, this inner chamber 11 is cuboid or cube-shaped, and the left side of this inner chamber 11 is provided with the left chute 111, the right side that are up and down trend and is provided with and is the right rail 112 of trend up and down.The interior slip of this left chute 111 is provided with left sealing plate 31, the interior slip of this right rail 112 is provided with right sealing plate 32., 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, right flank and this water intake 13 of this right sealing plate 32 match., 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 left surface that the right flank of this left sealing plate 31 is provided with upper left fixture block 311 and lower-left fixture block 312, 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 and have 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 be equipped with elastic insert 41 between the left side of this connecting plate 40 and this upper left fixture block 311, lower-left fixture block 312 and between He Gai upper right, the right side fixture block 321 of this connecting plate 40, 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 that is positioned at this inner chamber 11 on this valve rod 20 is provided with limiting stopper 21.That is, this limiting stopper 21 makes this valve rod 20 suitable height that only can rise, so as not to this valve rod 20 while being subject to larger upwards tractive force this valve rod 20 and this connecting plate 40 depart from.The outside part that this valve rod 20 is positioned at this inner chamber 11 is provided with outside thread 22, on this outside thread 22, is arranged with nut 23, and these nut 23 outer rims have 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.On this valve body 10, be fixed with actuating motor 50, this actuating motor 50 is connected with retarder 60, is fixed with gear 70 on the output shaft of this retarder 60, and this gear 70 and this straight-tooth 231 engage.
Course of action of the present invention and working principle: after this actuating motor rotation, this retarder work, this gear rotarily drives this nut rotation.After this nut rotation, drive this valve rod to rise or decline.In the time that this valve rod rises, first the right side of this connecting plate drives this right sealing plate to rise, thus this water intake open in advance, water enters in the gap between this left sealing plate and this right sealing plate in and keeps in.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 then this water outlet is opened, and the water being temporary in this gap passes through this water outlet, and this control valve is opened.Otherwise in the time deserving this valve rod decline, first the right side of this connecting plate drives this right sealing plate to decline, thereby 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 this water outlet is closed to this control valve cut-off.That is to say, this water intake always opens and closes prior to this water outlet, thereby 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 actuating motor drives after nut rotation, utilize the principle of screw-nut body, make this left sealing plate and this right sealing plate action, also further reduce the difficulty of opening and ending.
It should be noted that, through lot of experiments, select L1 >=3(D+H), the parameters relationship of L2=D+H, can make this left sealing plate and right sealing plate have very appropriate unlatching opportunity, be conducive to reduce the design difficulty of this control valve.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; 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.
