Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of ball valve.
Background technique
Ball valve, is defined as in standard GB/T21465-2008 " valve term ": open-shut device (spheroid) is driven by valve rod, and the valve rotating around square work ball valve axis.Also can be used for adjusting and the control of fluid, be specially adapted to the medium of fibre-bearing, small solid particle etc.
The topmost valve base sealing loop material of ball valve is teflon, it has to nearly all chemical substance the inertia of being, and have that friction factor is little, stable performance, be difficult for comprehensive feature aging, that temperature applicable range is wide and sealability is good, but the physical property of teflon, comprise higher expansion coefficient, receptance to cold flow and bad thermal conductivity, require the design of valve base sealing to carry out around these characteristics.
In prior art, a kind of high-pressure ball valve is disclosed in the Chinese invention patent that is CN201410025465.2 at application number, its main points are: on the fitting surface of spherical installation cavity and spheroid, be provided with two annular caulking grooves, in annular caulking groove, valve seals is installed, valve seals and spheroid outer circumferential face are sealed and matched, the center line of valve seals and the center line of inlet channel; Between the inwall of each annular caulking groove and corresponding valve seals, be provided with spring, on valve seals, be also provided with seal ring mounting groove, in sealing circle mounting groove, the auxiliary seal ring coordinating with the inwall of annular caulking groove is installed, high-pressure ball valve in this invention can reduce the extruding force between spheroid and seal ring, reduce the unlatching moment of torsion of high-pressure ball valve, and increase the equilibrant force to seal ring, avoid seal ring to occur because elastic failure causes the phenomenon that sealability declines.
The sealability of ball lining is strengthened in this invention by be embedded all parts on valve base inner wall, but this structure is that the change of valve base inner wall is caused in ball valve processing, more complicated is installed, easily there is displacement in the liner that both sides valve body closes up inside while fixing, coming off causes its sealing to lose efficacy, and is unfavorable for producing and promotes.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of ball valve of simple in structure, easy for installation, long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of ball valve, comprise valve body, side valve body and spool, one end of described valve body is connected with one end of side valve body and is formed with valve pocket, described spool is encapsulated in described valve pocket, in described valve pocket, be equipped with valve rod, described valve rod one end is connected with spool, the other end extends in valve pocket outside, between described valve pocket and spool, be provided with seal ring, wherein: described spool circumferentially offer the first annular slot, described seal ring one side is embedded in described the first annular slot, the inwall of opposite side and valve pocket is conflicted, the side end face that described seal ring is embedded in the first annular slot offers the second annular slot, in described the second annular slot, be provided with elastic component, conflict with the sidewall of the second annular slot respectively in the two ends of described elastic component.
By adopting technique scheme, described seal ring is embedded the area of contact that has increased seal ring and spool in the mode of the first annular slot, thereby increase the sealability of described ball valve, and described the first annular slot provides deformation space for described seal ring, described seal ring under high pressure can not be extruded cracking when expanded by heating, extend the working life of described seal ring, the elastic component being simultaneously embedded in described the second annular slot no matter at described seal ring expanded by heating, when the cold contraction of hand, can afford redress, the sealability of described ball valve can not reduced because of temperature variation, in the time of assembling, described seal ring in advance inlay card in described the first annular slot, being communicated with spool packs in valve pocket together again, simplify the installation process of described ball valve.
The utility model is further set to: in described valve pocket with on the just right inwall of described seal ring, be provided with spine.
By adopting technique scheme, described spine thrusts in described seal ring, play fixation, prevent in the time opening, close spool, prevent that described seal ring and valve pocket from producing relative sliding, ensure one end that the side that contacts with spool of seal ring is relative movement, ensure the water-proof performance of described ball valve.
The utility model is further set to: the V-shaped setting in cross section of described elastic component, and the spring steel that is formed in one of described elastic component.
By adopting technique scheme, described elastic component simple in structure, convenient when mounted.
Compared with prior art, the utility model has the advantage of: be embedded in spool by seal ring, and the straight key of described seal ring and spool is provided with the technological scheme that elastic component is the distortion raising compensation of seal ring, when simplification ball valve internal structure makes ball valve be convenient to install, ensure that described ball valve can keep good sealability under different temperatures, has extended the working life of described ball valve simultaneously.
