Abstract
The utility model provides a kind of bush type ammonia butterfly valve, including valve body, valve rod and butterfly plate, and the valve rod is arranged in valve body, and the butterfly plate is arranged on the valve rod, is rotated around valve rod；Bushing is set on the valve body, protrusion is set on the bushing, is provided with gasket on the butterfly plate with protrusion corresponding position, the bushing is metal lining.The utility model overcomes deficiency in the prior art, and good seal performance, service life is long, disclosure satisfy that complex working condition demand.
Description
Technical field
The utility model is related to valve field more particularly to a kind of bush type ammonia butterfly valves.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in structure, can be used for the switch control of low pressure pipeline medium,
Closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation.In industrial fluids pipeline
In system, butterfly valve is commonly used as the equipment for adjusting fluid flow.With butterfly valve, its bushing is plastics to existing ammonia, sealing effect
Fruit is poor, and the pressure born is low, and life of valve is shorter, cannot meet complex working condition demand.
Utility model content
In view of this, the utility model provides a kind of bush type ammonia butterfly valve, deficiency in the prior art is overcome, it can
Meet complex working condition demand.
The utility model uses following technical scheme：
A kind of bush type ammonia butterfly valve, including valve body, valve rod and butterfly plate, the valve rod are arranged in valve body, the butterfly plate
It is arranged on the valve rod, is rotated around valve rod；Wherein, bushing is set on the valve body, protrusion is set on the bushing, it is described
Gasket is provided on butterfly plate with protrusion corresponding position, the bushing is metal lining.
Preferably, the gasket is fixed on through bolt on the butterfly plate.
Preferably, pressure spiral shell, the first sealing ring, axle sleeve and the second sealing ring, the pressure spiral shell are disposed in the valve body
It is set on valve rod, is connect with valve body screw thread；The axle sleeve is set on valve rod, and the first sealing ring setting is in pressure spiral shell and axis
Between set, second sealing ring is arranged between axle sleeve and bushing.
Preferably, first sealing ring and the second sealing ring are O-ring.
Preferably, the bushing is welded on the valve body.
The beneficial effects of the utility model are：
The bushing of the utility model uses metal lining, and the bushing of different metal materials can be welded according to dielectric property, from
And meet complex working condition demand, while the pressure that metal lining can be born is high, is hardly damaged, extends the service life of valve, drops
Low use cost.Protrusion is arranged in the utility model on bushing, and gasket is arranged with protrusion corresponding position on butterfly plate, improves
The sealing effect of valve；It is close using the first sealing ring and the second sealing ring twice in order to avoid medium is revealed and around butterfly plate
Envelope, further lift-off seal performance.

Specific implementation mode
As shown in Figure 1, the utility model provides a kind of bush type ammonia butterfly valve, including valve body 1, valve rod 2 and butterfly plate 7, valve
Bar 2 is arranged in valve body 1, and butterfly plate 7 is arranged on the valve rod 2 in valve body 1, is rotated around valve rod 2.Bushing 3 is set on valve body 1,
Bushing 3 is welded on valve body 1.Protrusion 4 is set on bushing 3,4 corresponding position of protrusion is provided with gasket 5 on butterfly plate 7, it is close
Packing 5 is fixed on through bolt 6 on butterfly plate 7.In the present embodiment, bushing 3 is metal lining, can weld different gold according to dielectric property
The bushing for belonging to material, to meet complex working condition demand, while the pressure that metal lining can be born is high, is hardly damaged, the valve longevity
Life length, reduces use cost.Protrusion 4 is arranged in the utility model on bushing 3, and is set with 4 corresponding position of protrusion on butterfly plate 7
Gasket 5 is set, avoids medium from being revealed between bushing 3 and butterfly plate 7, improves the sealing effect of valve.
Pressure spiral shell 9, the first sealing ring 11, axle sleeve 10 and the second sealing ring 8 are disposed in valve body 1, pressure spiral shell 9 is set in valve
On bar 2, it is threadedly coupled with valve body 1；Axle sleeve 10 is set on valve rod 2, the setting of the first sealing ring 11 pressure spiral shell 9 and axle sleeve 10 it
Between, the second sealing ring 8 is arranged between axle sleeve 10 and bushing 3.First sealing ring and the second sealing ring are O-ring, and first is close
Seal and the second sealing ring are rubber ring.The utility model is revealed in order to avoid medium, increases the first sealing ring and second close
Seal two seals compress the first sealing ring 11 and the second sealing ring 8, further lift-off seal using pressure spiral shell 9 and axle sleeve 10
Energy.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
