Description
Technical field
The present invention is a kind of electric orifice valve, is particularly suited for air-transport system and other occasion that seal request is high.
Background technology
At present, the flashboard of regular knife gate valve is solid slab, and when valve is opened, channel cross-section has sudden change, easy dust stratification in passage.Adopt the machinerys such as alignment pin to be connected between flashboard with driving mechanism, transmission process cannot ensure flashboard rectilinear motion, cause the shortcomings such as transmission is unstable, transmission efficiency is low；Flashboard is pressed to valve seat by wedge briquetting by the sealing of valve by force, and owing to inevitably there will be the situation of the abrasion of wedge briquetting and wedge briquetting and the blocking of valve seat gap in running, its sealing reliability is low, poor sealing performance.
Summary of the invention
The present invention provides a kind of electric orifice valve, and when this electric orifice valve is in the open position, inner passage is smooth without sudden change, not dust stratification；Time in the closed position, good sealing effect；Having rack structure bottom its valve plate, tooth bar engages with travelling gear and realizes valve plate linear running, and stable drive, efficiency are high, and valve plate is break-make part and driving member.This electric orifice valve adopts mechanical spring type hold down gag to ensure its sealing effectiveness, and it compresses degree scalable, thoroughly solves the defect that conventional seals exists.
What the present invention adopted technical scheme is: a kind of electric orifice valve, is mainly made up of upper valve body, lower valve body, valve plate, hold down gag, actuating device, control device and drive motor.Described upper valve body is provided with inlet tube；Described lower valve body is provided with outlet and two valve plate guide rail；Described valve plate is break-make part and driving member, and its plane has through hole, and transverse section is " inverted concave ", and two bottom sides is rack structure；Described hold down gag is mechanical spring type version；Described actuating device includes one group of worm and gear, little a pair gear and a power transmission shaft horizontal through lower valve body and guide rail, worm gear and little gear and is installed on power transmission shaft, little gear separation guide rail both sides；Described control device comprises proximity switch and limit induction block；The axle of described drive motor is combined as a whole by key and worm screw.
During valve event, motor direct-drive worm screw, driving force is delivered on valve plate tooth bar drives valve plate to do rectilinear motion via worm screw, worm gear, power transmission shaft, little gear.When import and export pipe and valve plate through hole completely through time, proximity switch receives action after the signal that the transmission of limit induction block comes, and motor stalls, valve plate stop motion, valve is in " reaching position " state, now, smooth without sudden change in whole transfer passage；When valve plate inverted running to valve plate through hole misplaces completely with import and export pipe, proximity switch receives signalizing activity, motor stalling, valve is in " pass puts in place " state, now, valve plate is fastened on outlet by hold down gag, it is ensured that valve has good sealing effectiveness.
The invention has the beneficial effects as follows, overcoming the shortcoming such as the inner passage abrupt change of cross-section, easy dust stratification when regular knife gate valve is opened, it is possible to properly functioning for a long time, good sealing effect, drive mechanism stable drive, transmission efficiency are high.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of electric orifice valve, mainly it is made up of upper valve body 1, lower valve body 2, valve plate 3, hold down gag 4, actuating device, control device and drive motor 5；
Upper valve body 1, lower valve body 2 connect as a whole by bolt assembly, and the sealing of valve body is added sealing gasket by between upper and lower valve body, is realized by clamping screw.
Valve plate 3 is break-make part and driving member, and its plane has through hole, and clear size of opening and upper valve body inlet tube 6, lower valve outlet pipe 7 are equivalently-sized.Valve plate 3 transverse section is " inverted concave ", and two bottom sides is rack structure, and valve plate 3 lower surface contacts firmly with outlet 7 upper surface.
Actuating device includes one group of worm gear 9 worm screw 10, little a pair gear 11 and a power transmission shaft 12.Worm gear 9 and little a pair gear 11 are installed on power transmission shaft 12, and power transmission shaft 12 is horizontal through lower valve body 2 and guide rail 8, and little gear 11 is lived apart guide rail 8 both sides, engages with valve plate 3 both sides tooth bar.Worm screw 10 is installed vertically on lower valve body 2, engages with worm gear 9.
Control device and comprise proximity switch 13 and limit induction block 14.
Drive motor 5 is arranged on upper valve body 1, and motor shaft is combined as a whole by key and worm screw 10.Drive motor 5 drives worm screw 10 to rotate, and worm screw 10 drives two little gear 11 synchronous axial system by worm gear 9, power transmission shaft 12, thus driving tooth-like valve plate 3 advance on guide rail 8 or retreat, valve plate 3 becomes driving member and participates in transmission.
In the embodiment shown in fig. 1, when valve plate 3 inverted running to valve plate through hole misplaces completely with inlet tube 6, outlet 7, proximity switch 13 obtains signal, motor 5 shuts down, valve plate 3 is out of service, and valve is in " pass puts in place " state, now, valve plate 3 is fastened on outlet 7 by hold down gag 4, it is ensured that valve has good sealing property.
In the embodiment depicted in figure 2, when valve plate 3 run to through hole and inlet tube 6, outlet 7 completely through time, the proximity switch 13 being arranged on lower valve body 2 obtains the signal that the limit induction block 14 on valve plate 3 sends, motor 5 shuts down, valve plate 3 is out of service, and valve is in " reaching position " state, now, smooth nothing sudden change, not easily dust stratification in whole transfer passage.
As shown in Figure 4, hold down gag 4 is mechanical type compressing device, is formed by regulating pressure cap 15, spring base 16, compression spring 17, locking nut 18 and pressure head 19；Spring base 16 is " T " shape, is installed in upper valve body 1 through hole, and it is outside is screw thread, and centre is step through-hole；Compression spring 17 and pressure head 19 are placed in spring base intermediate throughholes, it is ensured that pressure head 19 is pressed onto the upper surface of valve plate 3；Regulating pressure cap 15 is I.S.S, is threaded onto on spring base 16, and for regulating the compression degree of compression spring 17, whole spring base 16 is locked by locking nut 18.This design ensures no matter when valve plate 3 all closely fastens with outlet 7, and valve has good sealing effectiveness；Valve plate 3 lower surface and outlet 7 upper surface are polished surface, and when therefore valve plate 3 and outlet 7 fasten operation, frictional resistance is less, and drive motor 5 is low-power machine.
