Abstract
Relate to the two-way V-type adjustable sealing butterfly valve of butterfly valve, butterfly plate connects on valve body by valve shaft, valve seals is connected on valve body, butterfly plate seal ring is connected on butterfly plate, described V-shaped seal ring is connected between valve seals and butterfly plate seal ring, described trim ring is connected on valve body by set screw, and described body circle tuned plate is connected on valve body by adjusting screw, and valve seals and V-shaped seal ring are respectively on the otch of body circle tuned plate.V-shaped seal ring of the present utility model can float adjustment in valve body, and have good rigidity and flexibility, when making valve bear medium forward and reverse pressure, sealability is reliable.
Description
Technical field
The utility model relates to butterfly valve.
Background technique
At present, the metal hard-sealing butterfly valve used in each engineering, its butterfly plate seal ring all adopts eccentric structure, and valve seals is H type seal ring or L-type seal ring, the seal ring of L-type withstands on seal ring, and the adjusting screw on the trim ring of its L-type is for regulating the pressure of seal ring.After adjusting screw is tightened, pressure is excessive, makes seal ring not have floatability.After adjusting screw is unscrewed, make pressure diminish, easily occur leaking.And H type seal ring rigidity is strong, flexible poor, L-type seal ring is flexible, poor rigidity.
Summary of the invention
The purpose of this utility model is to provide: two-way V-type is floated adjustable sealing butterfly valve, and it is that a kind of floatability is good, the reliable butterfly valve of sealability.
For achieving the above object, the technical solution of the utility model is:
The utility model comprises transmission device, valve shaft, valve body, butterfly plate, valve seals, butterfly plate seal ring, V-shaped seal ring, set screw, adjusting screw, trim ring, body circle tuned plate, be connected with the top of valve shaft in transmission device, and transmission device is positioned at the top of valve body, butterfly plate connects on valve body by valve shaft, valve seals is connected on valve body, butterfly plate seal ring is connected on butterfly plate, described V-shaped seal ring is connected between valve seals and butterfly plate seal ring, described trim ring is connected on valve body by set screw, described body circle tuned plate is connected on valve body by adjusting screw, valve seals and V-shaped seal ring are respectively on the otch of body circle tuned plate.
Advantage of the present utility model is:
1, because V-shaped seal ring of the present utility model can float adjustment in valve body, valve bear medium forward and backpressure reliable for effect;
2, V-shaped seal ring of the present utility model has the advantage of H type seal ring and L-type seal ring, makes sealability reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged view of Fig. 1.
Embodiment
See accompanying drawing embodiment, the utility model is described in further detail.
In Fig. 1-2: be connected with the top of valve shaft 2 in transmission device 1, transmission device 1 is at the top of valve body 7, butterfly plate 8 is connected on valve body 7 by valve shaft 2, valve seals 9 is connected on valve body 7, butterfly plate seal ring 10 is connected on butterfly plate 8, V-shaped seal ring 11 is connected to the centre of valve seals 9 and butterfly plate seal ring 10, trim ring 5 is connected on valve body 7 by set screw 3, adjusting screw 4 is connected with body circle tuned plate 6 through valve body 7, and valve seals 9 and V-shaped seal ring 11 are respectively on the otch of body circle tuned plate 6.
When valve opening, medium positive pressure, V-shaped seal ring 11 can float adjustment in valve body 7, by tightening adjusting screw 4, can arrive reliable sealing effect.Due to the otch of body circle tuned plate 6 and the restriction of spacing seam, ensure that the domain of walker of V-shaped seal ring 11, also prevent the upset of V-shaped seal ring 11 simultaneously.
When the valve is closed, V-shaped seal ring 11 moves down by pressure medium and is adjacent to butterfly plate seal ring 10, and meanwhile, V-shaped seal ring 11 inwardly shrinks by medium power, makes sealing effect reliable.
