Description
Technical field
The utility model relates to a kind of butterfly valve more particularly to a kind of dust-proof butterfly valves of semifixed axis.
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.Valve can
For controlling the various types such as empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium
The flowing of fluid.Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Axis around its own rotates, to achieve the purpose that opening and closing or adjusting.Existing butterfly plate lower end is equipped with lower valve rod, valve interior wall
It is equipped with fixing seat, lower valve rod is placed in rotation in fixing seat, and long long afterwards using the time, lower valve rod can be generated with fixing seat inner wall
Crystallization, accumulation for a long time will cause lower valve rod rotation painstakingly, stuck, influence working efficiency.
Utility model content
In view of the foregoing drawbacks, quick and easy for installation the purpose of this utility model is to provide a kind of structure is simple, avoid valve
Crystallization is generated between bar and axle sleeve, is prevented dust from accumulating in axle sleeve and is caused a kind of stuck semifixed dust-proof butterfly valve of axis.
Thus the technical scheme adopted by the utility model is
Including valve body, valve rod and butterfly plate, the butterfly plate is built in valve body, is equipped in the valve body and is placed in butterfly plate side
Valve seat, valve rod lower end are fixedly connected with butterfly plate upper end, and pressure ring is fixedly connected on the butterfly plate, is set between the pressure ring and butterfly plate
There is the sealing ring with valve seat cooperation, the bearing valve shaft being located on valve interior wall is equipped with below the butterfly plate, butterfly plate lower end is equipped with solid
Determine hole, Lower shaft sleeve is installed in the fixation hole, Upper shaft sleeve is cased on the valve rod, the Upper shaft sleeve is mounted on body wall
On, helicla flute is offered on the inner wall of the Upper shaft sleeve and Lower shaft sleeve, the Lower shaft sleeve is socketed on bearing valve shaft, the bearing
The centerline of valve shaft is equipped with the gas hole through valve body, the shaft centre line of the bearing valve shaft and the shaft centre line weight of valve rod
It closes.
As a further improvement of the above technical scheme, the sealing ring is ceramic-seal ring.
As a further improvement of the above technical scheme, gasket seal is equipped between the sealing ring and butterfly plate.
As a further improvement of the above technical scheme, the outer end of the gas hole is equipped with capping.
The utility model has the advantages that:
The utility model structure is simple, quick and easy for installation, using the utility model structure, generates between valve rod and axle sleeve
Impurity can be moved down and fall by helicla flute, prevent dust from accumulating in axle sleeve and cause valve rod stuck, while can also keep away
Exempt to generate crystallization, stable and reliable working performance between valve rod and axle sleeve.
