Abstract
The invention discloses a fireproofing ball valve. The fireproofing ball valve comprises a valve body, a valve seat and a ball body, wherein a spring and a first O-shaped sealing ring are arranged between the valve body and the valve seat; the valve seat is provided with a socket; the socket is internally provided with a plug-in component; a graphite block is arranged at the inner side of the first O-shaped sealing ring on the valve seat; and a second O-shaped sealing ring is further arranged between the valve seat and the valve body. With the adoption of the fireproofing ball valve, the graphite block is arranged at the inner side of the first O-shaped sealing ring on the valve seat; and the second O-shaped sealing ring is further arranged near the inner side of the graphite block on the valve seat, so that the use demands of the ball valve in different occasions can be satisfied and fire protection can be realized.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of fire prevention ball valve.
Background technique
Ball valve is used one of valve comparatively widely, and its working principle is the same with stopcock, all is to make valve opening and closing by rotary spool, but lighter than stopcock switch, relative volume is little, can make the heavy caliber ball valve.Ball valve sealing is reliable, and is simple in structure, easy to maintenance, and sealing surface and the spheroid closed state of being everlasting is difficult for by the medium erosion, thereby is widely used in industries such as oil, chemical industry, metallurgy.
The spheroid 3 that existing ball valve generally comprises valve body 1, valve seat 2 and seals is provided with spring 4 and O-ring seals 5 between valve body 1 and the valve seat 2, offer slot on the valve seat; Be provided with a nonmetallic plug-in unit 6 in the slot, the spheroid of ball valve is fixed, and does not produce mobile behind the pressurized; After valve seat receives hydrodynamic pressure, produce and move, make plug-in unit can be pressed on the spheroid; To guarantee sealing, on valve seat, also be provided with a graphite block 7, be used for fire prevention.Ball valve generally comprises single piston effect and double-piston effect ball valve, and referring to Fig. 1, shown in 2, single piston effect has only inlet seal or exit seal; The double-piston effect is the inlet-outlet bidirectional sealing; Necessarily also need have safe pressure relief device, because single piston effect ball valve is different fully with the valve seat construction of double-piston effect ball valve, therefore if will be when different occasions is used; Different ball valves certainly will be needed, cost will be increased like this.
Summary of the invention
The object of the invention provides a kind of fire prevention ball valve, through the improvement to structure, makes ball valve can satisfy the use needs of different occasions, and can prevent fires.
Technological scheme of the present invention is: a kind of fire prevention ball valve; Comprise valve body, valve seat and spheroid; Said valve body and valve base chamber are provided with the spring and first O-ring seals, offer slot on the said valve seat, are provided with plug-in unit in the said slot; Be positioned at the said first O-ring seals inboard on the said valve seat and be provided with graphite block, also be provided with second O-ring seals on the said valve seat and between said valve body.
Further technological scheme, said second O-ring seals are arranged at nearly said graphite block inboard on the said valve seat.
In the technique scheme, this ball valve is made up of valve body, valve seat and spheroid, and valve body and valve base chamber are provided with the spring and first O-ring seals, offer slot on the valve seat, are provided with nonmetallic plug-in unit in the slot, and nonmetal plug-in unit contacts with spheroid realizes sealing.Ball valve of the present invention is through being provided with graphite block in the first O-ring seals inboard; The structure that had so both kept double-piston effect ball valve; Also can prevent fires, and can be provided with second O-ring seals, so just can be used as single piston effect ball valve and use through the place, inboard of nearly graphite block on valve seat; Second O-ring seals is not set, then can continues to use as double-piston effect ball valve.
Advantage of the present invention is:
1. the present invention is provided with graphite block through the first O-ring seals inboard on valve seat; And nearly graphite block inboard is provided with second O-ring seals on valve seat; Making ball valve both can be used as double-piston effect ball valve uses; Also can be used as single piston effect ball valve and use, satisfied different user demands, and had fire-proof function;
2. the present invention is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is single piston effect ball-valve structure schematic representation in the existing technology;
Fig. 2 is a double-piston effect ball-valve structure schematic representation in the existing technology;
Fig. 3 is the structural representation of the embodiment of the invention one.
Wherein: 1, valve body; 2, valve seat; 3, spheroid; 4, spring; 5, O-ring seals; 6, plug-in unit; 7, graphite block; 8, valve body; 9, valve seat; 10, spheroid; 11, spring; 12, first O-ring seals; 13, plug-in unit; 14, graphite block; 15, second O-ring seals.
Embodiment
Embodiment one: referring to shown in Figure 3; A kind of fire prevention ball valve; Comprise valve body 8, valve seat 9 and spheroid 10,9 of said valve body 8 and valve seats are provided with the spring 11 and first O-ring seals 12, offer slot on the said valve seat 9; Be provided with plug-in unit 13 in the said slot; Be positioned at said first O-ring seals 12 inboards on the said valve seat 9 and be provided with graphite block 14, on the said valve seat 9 and 8 of said valve bodies also be provided with second O-ring seals 15, said second O-ring seals 15 is arranged at nearly said graphite block 14 inboards on the said valve seat 9.
Ball valve in use; Inboard at first O-ring seals is provided with graphite block; Ball valve promptly can be used as the use of double-piston effect ball valve like this; When the place, inboard of nearly graphite block on valve seat was provided with second O-ring seals, ball valve just can be used as single piston effect ball valve and uses, thereby satisfies different use needs.Because the cross section of graphite block generally is 3 * 3,4 * 4,5 * 5, so change of the present invention is very convenient.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
