Abstract
The utility model relates to a liquid level driving float which is provided with a guiding cylinder arranged below a fixing body, driving float locating holes respectively arranged on the two sides above the fixing body, a driving float arranged on the outer diameter of the fixing body, a hitch pin arranged above the driving float, a driving float location block arranged below the guiding cylinder, a guiding location block arranged in the guiding cylinder, a push rod arranged in the centre of the guiding cylinder, a control float arranged below the push rod, and a locking plate union body corresponding to the driving float locating holes arranged above the push rod. Two reverse eight-shaped localization locking plates are hinged on the locking plate union body. The utility model is suitable for driving devices which need displacement and reversing of liquid level control like electric directional control valve, air-operated directional control valve, hydraulically operated direction control valve, switches, etc.
Description
The invention belongs to the actuating float.
The existing float that activates as the actuating float of running water switch, is made up of fixed body, float, bolt rope, lever, and float moves up and down with the lifting drive lever of liquid level, drives closing and opening of running water switch.This liquid level activates float, can only slowly drive the unlatching of driven device or closes.
The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of can be instantaneous the liquid level of driving driven device displacement commutation activate float.
For achieving the above object, feature of the present invention is that the fixed body below is provided with guide cylinder, both sides, guide cylinder top are respectively equipped with the driving float positioning hole of break-through, the guide cylinder external diameter is provided with the driving float that slides up and down, drive the float top and be provided with hitching post, the guide cylinder below is provided with and drives the float positioning block, be provided with the guide-localization piece in the guide cylinder, guide-localization piece center is provided with the push rod that slides up and down, the push rod below is provided with the control float, the push rod top is provided with the locking plate union body, and the float positioning hole is corresponding with driving, two location locking plates that are down " eight " word shape of hinge connection on the locking plate union body.
The center hole that the driving float is inserted in guide cylinder is a cone shape hole.
Two location are provided with stage clip between the locking plate top.
The present invention has certain distance owing to drive float with liquid level, can instantaneous driving driven device during landing, be applicable to the drive unit of need that liquid level control displacement commutates electric, pneumatic, hydraulicchange-over valve, switch etc.
Description of drawings
Accompanying drawing is a kind of schematic representation of the present invention, also is a kind of embodiment's schematic representation.
Provide embodiment below in conjunction with accompanying drawing, the invention will be further described.
Embodiment: liquid level as shown in the figure activates float, and fixed body 11 belows are provided with guide cylinder 5, and convenient for fabrication and installation, guide cylinder 5 is divided into two-part up and down, is linked together by guide-localization piece 6.Both sides, guide cylinder 5 top are respectively equipped with the driving float positioning hole 10 of break-through.Guide cylinder 5 external diameters are provided with the driving float 3 that can slide up and down, and drive float 3 tops and are provided with hitching post 4.Guide cylinder 5 belows are provided with and drive float positioning block 2, to prevent that driving float 3 deviates from, also can be push rod 7 guiding simultaneously.The center of the guide-localization piece 6 that is provided with in the guide cylinder 5 is provided with the push rod 7 that can slide up and down, and guide-localization piece 6 can prevent that push rod 7 from skidding off for push rod 7 guiding and location.Push rod 7 belows are provided with control float 1, and push rod 7 tops are provided with locking plate union body 8.Positioning hole 10 is corresponding with driving, two location locking plates 9 that are down " eight " word shape of hinge connection on the locking plate union body 8, because location locking plate 9 is down " eight " word shape, can under the effect of self gravitation, open voluntarily, top is stretched out drive locking plate hole, float location 10, support drive float 3 also can be provided with stage clip 12 above between two location locking plates 9, promote two location locking plates 9 and open, can also below two location locking plates 9, be respectively equipped with extension spring.The center hole that driving float 3 is inserted in guide cylinder 5 is a cone shape hole, can cross open locking plate 9 at an easy rate.During use, hitching post 4 by bolt rope bolt on the operating mechanism of driven device.When liquid level rises, control float 1 and drive float 3 and rise with liquid level.Control float 1 promotes push rod 7 and moves upward, and when locking plate 9 rose to driving float positioning hole 10 places, locking plate 9 opened under the effect of self gravitation, stretches out to drive float positioning hole 10.Driving float 3 also floats simultaneously upward, when rising to driving float positioning hole 10, under the effect of liquid buoyancy, overcome the buoyancy of locking plate 9 self gravitations and control float 1, make locking plate 9 closures, cross locking plate 9, locking plate 9 promptly opens under the effect of self gravitation, support drive float 3, driven device displacement commutation.When liquid descends, drive float 3 and under the support of open locking plate 9, continue to remain on original position.When liquid level dropped to certain position, control float 1 drove push rod 7 and descends, and drives locking plate 9 closures, enters in the guide cylinder 5, limits the position by guide-localization piece 6.Drive float 3 and lose support decline rapidly, through the instantaneous drive driven device displacement of bolt rope commutation.
