Description
Technical field
The utility model relates to a kind of butterfly valves, more particularly to a kind of butterfly valve that can prevent valve rod card resistance.
Background technique
Butterfly valve is to develop a kind of faster valve in the past 20 years, and structure is that have a circular valve plate in valve body, is passed through
The support of valve rod can rotate in valve body, and valve rod is mounted on valve body by axle sleeve, keep butterfly valve fast with it by its design feature
Speed opening and closing, the easy to operate and equipment generally selected when becoming pipeline liquid, but under special environment condition, as conveying contains
When the big liquid of sediment concentration, often the butterfly valve of ordinary construction generates card resistance since impurity enters between valve rod and axle sleeve, makes valve
The leakproofness of door is unreliable or valve rod rotates not flexible, even stuck phenomenon is caused often using common butterfly valve opening and closing difficulty
Repair or scrap phenomenon.
Summary of the invention
The utility model can prevent silt, dust from entering valve rod and shaft room to solve the above problems, providing one kind
Anti- valve rod card resistance butterfly valve.
Technical solution adopted in the utility model:
A kind of butterfly valve of anti-valve rod card resistance, including valve body, valve rod, butterfly plate, bracket and transmission device, valve body are right above and below
An axis hole should be offered, valve rod passes through axis hole and is fixedly connected with butterfly plate by straight pin, and valve body and butterfly plate cooperatively form opening and closing
The upper/lower terminal of access, valve rod is arranged disk spring in the gap of butterfly plate and valve body, and valve rod both ends are in the axis hole position of valve body point
Not She Zhi Upper shaft sleeve and Lower shaft sleeve, valve rod fills filler, filling out on valve rod in the gap between the top and axis hole of Upper shaft sleeve
Material top is arranged pressing plate, and the top of valve rod and transmission device are affixed, and the top of valve body is fixed by bolt, nut and frame bottom
Connection, the top of bracket is fixedly connected by bolt, nut with the bottom of transmission device.
Lower cover plate sealing is bolted in the body base.
The valve rod bottom end is against on lower cover plate, and stem lower portion is in Lower shaft sleeve lower end corresponding position open loop connected in star, ring
The split annulus of setting in connected in star, split annulus are blocked in the lower end surface of Lower shaft sleeve.
The utility model has the beneficial effects that the utility model is covered in the upper/lower terminal of valve rod in the gap of butterfly plate and valve body
If disk spring, prevent dust, particle from entering between valve rod and axis hole, the soft filler filled between valve rod and axis hole, filler and valve
Very close to each other between bar, impurity cannot be introduced between valve rod and filler, even if when dust, the particle in pipeline enter axis hole and valve rod
Between when can also be contained by soft filler, card resistance will not be caused.

Specific embodiment
A kind of butterfly valve of anti-valve rod card resistance, including valve body 2, valve rod 5, butterfly plate 4, bracket 8 and transmission device 7, on valve body 2,
Under it is corresponding offer an axis hole, valve rod 5 passes through axis hole and is fixedly connected with butterfly plate 4 by straight pin 6, valve body 2 and the cooperation of butterfly plate 4
The access of opening and closing is formed, the upper/lower terminal of valve rod 5 is arranged disk spring 3 in the gap of butterfly plate 4 and valve body 2, and 5 both ends of valve rod exist
Upper shaft sleeve 13 and Lower shaft sleeve 14 is respectively set in the axis hole position of valve body 2, between valve rod 5 is between the top and axis hole of Upper shaft sleeve 13
Filler 12 is filled in gap, pressing plate 11 is arranged above filler 12 on valve rod 5, the top of valve rod 5 and transmission device 7 are affixed, valve body 2
Top be fixedly connected by bolt 10, nut 9 with 8 bottom of bracket, the top of bracket 8 is filled by bolt 10, nut 9 and transmission
7 bottom is set to be fixedly connected.
2 bottom of valve body connects 1 sealing of lower cover plate by bolt 10.
5 bottom end of valve rod is against on lower cover plate 1, and 5 lower part of valve rod is recessed in 14 lower end corresponding position open loop shape of Lower shaft sleeve
Slot, the interior split annulus 15 of setting of annular groove, split annulus 15 are blocked in the lower end surface of Lower shaft sleeve 14.
In application, the filler 12 filled between valve rod 5 and axis hole can be used for containing the impurity in pipeline medium, valve rod 5 it is upper,
Lower both ends are arranged disk spring 3 in the gap of butterfly plate 4 and valve body 2, prevent dust, particle from entering the axis hole on valve rod 5 and valve body 2
