Summary of the invention
Purpose of utility model: purpose of the utility model is to solve deficiencies in the prior art, provide one kind and are convenient for
Different flow size is adjusted, maximum stream flow can be locked and reduces a kind of novel manual butterfly valve of torsional forces.
Technical solution: a kind of novel manual butterfly valve of the utility model, including valve body, valve body is interior to be equipped with valve plate, valve plate and valve
Bar is connected, and the top of valve rod is equipped with first gear, and the first gear on valve rod is meshed with the second gear on connecting column, connects
The end of column is equipped with rotating disk, and the valve rod below first gear is equipped with limiting device, and valve body inward flange is equipped with sealing ring, valve plate
Front and back two sides be all provided with it is fluted.
Further improvement of the utility model is that the groove on valve plate two sides is multiple groups, the spacing phase between multiple groups groove
Groove Deng, valve plate two sides is symmetrical arranged.
Further improvement of the utility model is that groove is equipped with curved cover plate, and the diameter of cover board is less than the straight of valve plate
Diameter.
Further improvement of the utility model is, sliding slot is equipped at the top of limiting device, and sliding slot is equipped with a pair of symmetrical
Limit plate, valve rod are equipped with a pair of slide, and a pair of slide is respectively provided in the sliding slot that limit plate is separated out.
Further improvement of the utility model is that slide plate two sides are arc, and limit plate two sides are also arc, limit plate two
The arc of side and the radian of slide plate two sides match.
Further improvement of the utility model is that valve rod runs through valve plate centre bore.
The utility model has the advantages that
1. the first gear on valve rod is meshed with the second gear on connecting column, the number of gears be it is fixed, rotate
An adjustable angle, realizes the adjusting of uninterrupted.
2. the groove of two sides setting before and after valve plate, reduces the torsional forces of valve plate opening and closing, meanwhile, also play extension valve
The effect in plate service life.
3. the setting of limiting device limits the 360 degree rotation of valve plate.
4. when slide plate is bonded with sliding slot, maximum flow plays the role of pinpoint.
5. valve rod runs through valve plate centre bore, and the unconventional side that valve rod is fixed on to valve plate avoids radial disbalance
Adverse effect.
6. curved cover plate plays the role of protection, avoids direct impact of the water to valve plate, prolong when valve plate is closed
Service life is grown.

Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the utility model easily.
Such as Fig. 1-3, a kind of novel manual butterfly valve, including valve body 1, valve body 1 is interior to be equipped with valve plate 2, and valve plate 2 is connected with valve rod 3,
The top of valve rod 3 is equipped with first gear 11, and the first gear 11 on valve rod 3 is meshed with the second gear 12 on connecting column 4, the
One gear 11, second gear 12 are meshed for umbrella shape, and the end of connecting column 4 is equipped with rotating disk 5, the valve rod of 11 lower section of first gear
3 are equipped with limiting device 6, and 1 inward flange of valve body is equipped with sealing ring 7, and the front and back two sides of valve plate 2 is all provided with fluted 9.
Further, the groove 9 on 2 two sides of valve plate is multiple groups, and the spacing between multiple groups groove 9 is equal, 2 two sides of valve plate it is recessed
Slot 9 is symmetrical arranged.
Further, groove 9 is equipped with curved cover plate 14, and the diameter of cover board 14 is less than the diameter of valve plate 2.
Further, it is equipped with sliding slot 8 at the top of limiting device 6, sliding slot 8 is equipped with a pair of symmetrical limit plate 10, on valve rod 3
Equipped with a pair of slide 13, a pair of slide 13 is respectively provided in the sliding slot 8 that limit plate 10 is separated out.
Further, 13 two sides of slide plate are arc, and 10 two sides of limit plate are also arc, the arc and cunning of 10 two sides of limit plate
