Description
Technical field
The utility model relates to valve manufacture field, specifically a kind of shale gas high pressure mining butterfly valve.
Background technique
At existing common butterfly valve, be mostly to rely on valve plate and valve base sealing fitting closure passage.But in the mining of shale gas, the fracturing unit truck that adopts carries out work more, and so-called pressure break utilizes hydraulic action exactly, makes oil reservoir form a kind of method in crack, also known as oil formation hydraulic fracturing.Fracturing unit truck is just used to do formation fracturing technique, liquid high-pressure large-displacement with certain viscosity clamp-ons oil reservoir, after oil reservoir is extruded many cracks, add proppant (as silica sand etc.) filling and enter crack, improve the penetrating power of oil reservoir, to increase water injection rate (water injection well) or oil output (oil well).Common butterfly valve is under high pressure and full-bodied fluid matasomatism, and the life-span obviously shortens, and brings a large amount of economic losses.
Model utility content
The utility model aims to provide a kind of shale gas high pressure mining butterfly valve, by new structural design, improves butterfly valve working life, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of shale gas high pressure mining butterfly valve, is characterized in that: comprise valve body, the valve plate be arranged in valve body; Be installed with fixed core in the middle part of described valve plate, there is upper rotating shaft fixed core upper end by pinned connection, and upper rotating shaft is connected with drive unit through valve body, is provided with packing groove, is provided with packing seal pad in packing groove between upper rotating shaft and valve body; There is lower rotary shaft described fixed core lower end by pinned connection, and lower rotary shaft is arranged in the axis hole of valve body; Described valve plate designs for eccentric structure, and valve plate is convex conical plate near the side of flowing medium entry end, and valve plate is dull and stereotyped near flowing medium outlet section side; Be provided with reinforcing ribs in described convex conical plate, and middle part is provided with relief hole, fixed core is provided with the through hole with relief hole size adaptation.
Further, described valve body is provided with docking through hole.
Further, the inner peripheral surface that described valve body contacts with valve plate has seal groove, is provided with sealing rubber ring in seal groove.
The beneficial effects of the utility model are: valve plate of the present utility model adopts eccentric design, valve plate is convex conical plate near the side of flowing medium entry end, valve plate is dull and stereotyped near flowing medium outlet section side, when medium fluid acts on valve plate, according to taper to lateral flow, the intensity of pressure at valve plate center can be reduced.And middle part is provided with relief hole, fixed core is provided with the through hole with relief hole size adaptation, when opened butterfly valve, because pressure effect is excessive, may cause and cannot normally open and close, now rotate fixed core slowly to rotate, through hole on fixed core slowly aligns with relief hole, and pressure reduces gradually, carries out butterfly valve keying smoothly, avoid butterfly valve in the flimsy problem of hyperbaric environment, effectively improve the working life of butterfly valve.
Accompanying drawing explanation
Fig. 1 is the shale gas high pressure mining butterfly valve structure schematic diagram that the utility model provides.
Mark in figure: 1 be valve body, 2 be valve plate, 3 be fixed core, 4 be reinforcing ribs, 5 for docking through hole, 6 be relief hole, 7 be bearing pin, 8 be lower rotary shaft, 9 for upper rotating shaft.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of shale gas high pressure mining butterfly valve, is characterized in that: comprise valve body 1, the valve plate 2 be arranged in valve body 1; Be installed with fixed core 3 in the middle part of described valve plate 2, fixed core 3 upper end is connected with upper rotating shaft 9 by bearing pin 7, and upper rotating shaft 9 is connected with drive unit through valve body 1, is provided with packing groove, is provided with packing seal pad in packing groove between upper rotating shaft 9 and valve body 1; Described fixed core 3 lower end is connected with lower rotary shaft 8 by bearing pin 7, and lower rotary shaft 8 is arranged in the axis hole of valve body 1; Described valve plate designs for eccentric structure, and valve plate 2 is convex conical plate near the side of flowing medium entry end, and valve plate 2 is dull and stereotyped near flowing medium outlet section side; Be provided with reinforcing ribs 4 in described convex conical plate, and middle part is provided with relief hole 6, fixed core 3 is provided with the through hole with relief hole 6 size adaptation.Described valve body 1 is provided with docking through hole 5.The inner peripheral surface that described valve body 1 contacts with valve plate 2 has seal groove, is provided with sealing rubber ring in seal groove.
In use, valve plate 2 of the present utility model adopts eccentric design, valve plate 2 is convex conical plate near the side of flowing medium entry end, valve plate 2 is dull and stereotyped near flowing medium outlet section side, when medium fluid acts on valve plate 2, according to taper to lateral flow, the intensity of pressure at valve plate 2 center can be reduced.And middle part is provided with relief hole 6, fixed core 3 is provided with the through hole with relief hole 6 size adaptation, when opened butterfly valve, because pressure effect is excessive, may cause and cannot normally open and close, now rotate fixed core 3 slowly to rotate, through hole on fixed core 3 slowly aligns with relief hole 6, and pressure reduces gradually, carries out butterfly valve keying smoothly, avoid butterfly valve in the flimsy problem of hyperbaric environment, effectively improve the working life of butterfly valve.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
