To 90 ° come realize closing, unlatching and adjust flow valve, have it is simple in structure, it is small, it is easy to operate the advantages of, in work
Using very extensive in industry field.Butterfly valve in use, relies primarily on the periphery of valve plate and fitting closely for valve interior wall
It is sealed to realize, most of manually-operated butterfly valve, is all to realize the opening and closing of butterfly valve, e.g., hand by manually at present
Turn runner disc or valve rod, relatively elaborate gas are especially plugged or when runner is very sticky when encountering dish valve port, the power needed
Gas bigger, and also it is very easy to overexertion this when, cause one under shed of butterfly valve excessive, occur unexpected.
Therefore, the utility model is further studied on the basis of above.
Utility model content
Deficiency in for the above-mentioned prior art, the utility model provide a kind of laborsaving butterfly valve, can be stepped on by foot come
Realize the unlatching of butterfly valve, it is easy to operate and more laborsaving than with hand.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals.
A kind of laborsaving butterfly valve, including valve body, one end of the valve body is equipped with the first attachment, and the other end of valve body is equipped with second
Attachment, valve rod enter after sequentially passing through the first attachment and valve body in the second attachment, and the part that the valve rod is located in valve body is equipped with
For the dish plate of opening and closing, the valve rod is laterally set, one end of valve rod is equipped with annular gear wheel, the annular gear wheel and is vertically arranged
Liftable rack-plate mutually leans on, and annular gear wheel is engaged with the rack on rack-plate；The rack-plate is connected with one end of lever,
The lever rotation is set on support element, and the other end of lever is connected with pushing component, and the pushing component includes stepping on down for foot
Pressing plate, the lower compression leg set on lower platen lower end, the lower compression leg are set in lower pressing sleeve, and both ends are equipped in the lower pressing sleeve and are distinguished
The compressed spring of connecting bottom board and lower compression leg.
In this technology, in the lifting process of rack-plate, the rotation of the annular gear wheel engaged with rack can be driven, and then make
Valve rod rotates, and realizes unlatching and the closure of dish plate.Rack-plate is realized by lever construction and lifted, when people's foot is stepped down on lower platen
It waits, lower compression leg declines rack-plate simultaneously and rises；After foot unclamps lower platen, lower compression leg rises under compressed spring effect, tooth
Batten declines, and by way of placing weight on lower platen, can realize the holding of lower platen pressed status.
Preferably, the lower end of the rack-plate is equipped with connecting plate, which is movably arranged in lifting set, the lifting
The extension spring of both ends difference connecting bottom board and connecting plate is equipped in set.After pressure is removed on lower platen, extension spring can
To provide the power for pulling down connecting plate, coordinate with compressed spring, convenient for resetting.
Preferably, the back fixation of the rack-plate has support plate, it is lateral for being provided in rack-plate lifting process
Support force, rack-plate, will not deflection as between annular gear wheel and support plate at this time.
Compared with prior art, the utility model has the advantages that：One kind is provided to step on and can facilitate by foot
The butterfly valve of unlatching is operated compared to hand, and foot, which steps on operation, can provide the strength of bigger, makes whole operation more laborsaving controllable.
Description of the drawings
Fig. 1 is the schematic diagram that the rack-plate of the utility model rises.
Fig. 2 is the schematic diagram that the rack-plate of the utility model is fallen.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1 to Fig. 2, a kind of laborsaving butterfly valve, including valve body 3, one end of the valve body 3 is equipped with the first attachment 1, valve
The other end of body 3 is equipped with the second attachment 5, and the first attachment 1 and the second attachment 5 are equipped with pilot hole 11, and valve rod 2 sequentially passes through first
Enter in the second attachment 5 after attachment 1 and valve body 3, and can rotate；The part that the valve rod 2 is located in valve body 3 is equipped with to open
The dish plate 22 closed, the valve rod 2 laterally setting, one end of valve rod 2 are equipped with annular gear wheel 21, and the annular gear wheel 21 is with being vertically arranged
7 phase of liftable rack-plate lean on, and annular gear wheel 21 is engaged with the rack 71 on rack-plate 7；The rack-plate 7 and lever 6
One end be connected, the lever 6 rotation is set on support element 61, and the other end of lever 6 is connected with pushing component, the pushing component
Including lower platen 93, the lower compression leg 9 set on 93 lower end of lower platen stepped on for foot, the lower compression leg 9 is set in lower pressing sleeve 91, and institute
State the compressed spring 92 that both ends difference connecting bottom board 4 and lower compression leg 9 are equipped in lower pressing sleeve 91.
In present embodiment, the lower end of the rack-plate 7 is equipped with connecting plate 8, which is movably arranged at lifting set 81
