Technical field
The utility model relates to butterfly valve technical field more particularly to a kind of anti-jamming outboard bearing butterfly valves.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation.Butterfly valve opens
Closing member is a discoidal butterfly plate, is rotated in valve body around the axis of its own, to achieve the purpose that opening and closing or adjusting.With
The fast development of China's industrial manufacturing industry, it is also higher and higher for the demand of butterfly valve.But butterfly valve used at present, in height
Temperature, easily crystallization, under dirty medium in use, since material expansion unevenly makes valve shaft and axle sleeve is easily-deformable or foreign matter enters axis
It holds, causes to block, so that butterfly valve reduced service life.Based on this, the utility model devises a kind of anti-jamming outboard bearing butterfly
Valve, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of anti-jamming outboard bearing butterfly valves, to solve to mention in above-mentioned background technique
Existing apparatus out not can effectively prevent the problem of bite.To realize above-mentioned technical purpose and the technique effect, this is practical
It is novel to be achieved through the following technical solutions.
A kind of anti-jamming outboard bearing butterfly valve, including valve body, through being equipped between the top and bottom center of the valve body
Valve rod, the outer wall center rotation of the valve rod are socketed with valve plate, and the valve plate is located at the inner cavity center of valve body, the top of the valve rod
Portion and bottom are socketed with outboard bearing, are welded with support column at left and right sides of the top and bottom of the valve body, described external
Bearing is fixed by support column, the interior side contacts valve rod of the outboard bearing, and the contact position of the valve rod and valve body is equipped with adjustable
The filler assembly of pressing force, the bottom of the valve rod are connected with metal coating lid.
Preferably, in a kind of anti-jamming outboard bearing butterfly valve, the inner cavity of the filler assembly is equipped with filler-changeable.
Preferably, in a kind of anti-jamming outboard bearing butterfly valve, the bearing is mounted on the outside of filler assembly.
Preferably, in a kind of anti-jamming outboard bearing butterfly valve, the valve rod is equipped with nitriding hardened layer and chrome layer.
Preferably, in a kind of anti-jamming outboard bearing butterfly valve, the end of the filler assembly is equipped with gland, and gland and valve
Rod set connects.
The beneficial effects of the utility model are:
The structure design of the utility model is reasonable, and compared with prior art, the utility model by valve body, first fill out up and down by installation
Material seals at valve rod to realize, then the support column by being welded on valve body upper and lower part fixes outboard bearing, the length of support column
It can be reasonably selected according to the temperature of medium, achieve the purpose that reduce bearing temperature, outboard bearing can arbitrarily fill lubricating oil, lead to
After crossing cooling, bearing avoids local expansion deformation, while so that foreign matter is cannot be introduced into bearing by the sealing function of filler, effectively
Friction is reduced, it is efficiently anti-jamming, prolong the service life.
