Description

It is a kind of to switch light Hand-operated butterfly valve
Technical field
The utility model relates to valve body technology more particularly to a kind of switch light Hand-operated butterfly valve.
Background technique
Butterfly valve has the features such as structure is simple, switch is rapid, 90 ° of reciprocating rotatings, and driving moment is small, for being truncated, connecting, The medium in pipeline is adjusted, there are good fluid handling properties and closes sealing performance.As environmentally friendly emergency lagoon butterfly valve, usually It is mounted on subsoil drain, and this drainage pipeline is generally arranged among road or road two sides, thus heavy caliber butterfly The outer dimension of valve seems additional important.Heavy caliber Hand-operated butterfly valve generally used now is all made of the driving of handwheel mechanical transmission mechanism, And this transmission mechanism volume is big, weight weight, cost is high, and leakproofness is poor.
Therefore, can satisfy narrow space, switch light and flexible and tight-closed Hand-operated butterfly valve will be one urgently It solves the problems, such as.
Utility model content
The purpose of this utility model is that driven for current heavy caliber Hand-operated butterfly valve using handwheel mechanical transmission mechanism, And this transmission mechanism volume is big, weight weight, cost is high, leakproofness difference problem, propose it is a kind of switch light Hand-operated butterfly valve, should Hand-operated butterfly valve is suitable for small space, switchs light and flexible, tight-closed.
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.

Fig. 1 is the schematic diagram of internal structure that the utility model switchs light Hand-operated butterfly valve;
Fig. 2 is upper bearing support structure schematic diagram;
Fig. 3 is lower bearing seat structure schematic diagram;
Fig. 4 is the valve body structure schematic diagram that the utility model switchs light Hand-operated butterfly valve.
Specific embodiment
The present invention will be further described with reference to embodiments:
Embodiment 1
Light Hand-operated butterfly valve is switched present embodiment discloses a kind of, as shown in Figs 1-4, including valve body 9, valve rod are (also referred to as Valve shaft), valve plate 5 and the handle 8 being fixedly connected with valve stem tip, the valve plate 5 be rotatably provided in valve body 9, pass through rotary valve Plate 5 can block or open 9 fluid passage of valve body;The valve rod is radially connected with valve body 9 and valve plate 5 from 9 two sides of valve body, valve Bar and valve plate 5 are fixed, and 5 outer diameter of valve plate is matched with 9 internal diameter of valve body.9 bottom end of valve body is sealed completely by valve body lower end lid 1 It closes.
