In order to achieve the above purposes, the technical solution adopted by the utility model is: it is a kind of switch light Hand-operated butterfly valve, including
Valve body, valve rod, valve plate and the handwheel being fixedly connected with valve stem tip, the valve plate are arranged in valve body, and the valve rod is from valve body
Side passes radially through valve body and valve plate, and valve rod is fixed with valve plate；The valve rod upper end and valve body junction are provided with axis
Seat is held, is provided with single-row radial ball bearing between the valve rod and top chock；The valve rod lower end is set with valve body junction
It is equipped with step, between the valve rod and step, is coaxially arranged with single-row tapered roller bearing and unidirectional from top to bottom
Thrust ball bearing；It is provided with sealing ring between the top chock and valve rod, is provided between the step and valve rod close
Seal.
Further, the sealing ring is polytetrafluoroethylene (PTFE) J-type sealing ring, polytetrafluoroethylene material acid and alkali-resistance.
Further, it is provided between spindle nose on the top chock and valve plate above the single-row radial ball bearing close together
Seal prevents outside liquid from entering upper end bearing along spindle nose on valve plate.
Further, two seals are provided between the top chock and valve rod below the single-row radial ball bearing,
Prevent pipeline corrosion liquid from entering bearing.
Further, to be provided with two pass between the step and valve rod above the single-row tapered roller bearing close
Seal.
Further, the valve body inner periphery lining one encloses polyfluortetraethylene plate, can prevent valves leakage and valve body
Sealing surface corrosion.
Further, the valve body bottom end is completely enclosed by valve body lower end lid.
The utility model is a kind of, and to switch light Hand-operated butterfly valve simple and reasonable for structure, have compared with prior art with
Lower advantage:
1) the utility model switchs light Hand-operated butterfly valve and is able to satisfy subdrainage large aperture Pipe installing, convenient for installing
In narrow space, and switch light and flexible.Diameter is more than the Hand-operated butterfly valve of 300mm at present, will configure machine driving
The volume of structure, this transmission mechanism is even more than the volume of valve body.The utility model is added in valve plate spindle nose turned position
Rolling bearing switchs light and flexible without being equipped with bulk mechanical drive mechanism.
2) utility model switchs light Hand-operated butterfly valve good airproof performance, adds above spindle nose bearing one poly- four on valve plate
Fluorine sealing ring, prevents environmental liquids from entering in valve, and the position that spindle nose is contacted with liquid in pipeline above and below valve plate respectively adds twice
Polytetrafluoro sealing ring, in order to avoid corrosive liquid corrosion valve plate spindle nose and bearing.
3) utility model switchs light Hand-operated butterfly valve relative to traditional similar product, and rationally, structure is simple, cost for design
It is cheap.Rolling bearing is applied directly in the shaft of valve by the utility model.And eliminate biography that is more heavy and involving great expense
Motivation structure, total cost reduce very much.
