Description
Technical field
The utility model belongs to valve field, is specifically related to the full welded ball valve of a kind of directly buried type.
Technical background
Welding ball valve uses all widely in every field, its superior quality and high performance stability are that Normal Steel Casting ball valve is beyond one's reach, welding ball valve is far longer than cast steel ball valve working life, and all-welded ball valve is widely used on the various pipes equipment such as gas, city heat supply, petrochemical industry, shipbuilding, iron and steel, voltage regulating station, power station.
And modern city vehicle and pedestrian intensive, road conditions is complicated, safety requirement for gas is more and more higher, construction and when safeguarding fuel gas supply conduit and heat supply supply line, the requirement of pipe-line system safety is also improved thereupon, otherwise pipeline network of fuel gas in city produce leakage can bring major safety risks.
Model utility content
It is better that the utility model has aimed to provide a kind of sealability, the practical safer full welded ball valve of directly buried type.
For achieving the above object, the technical solution of the utility model is as follows:
The full welded ball valve of directly buried type, comprises left valve barrel, right valve barrel, base, valve body connector, valve rod, valve stem connection and spheroid, it is characterized in that: left and right valve body, connects into an overall valve body with valve body connector by full weld; Described valve rod is divided into upper valve rod and lower valve rod, is connected respectively to valve body by valve stem connection; Described spherome surface is provided with abrasion-resistance glass steel layer, is placed in valve body; Described base is arranged on below valve body; Be provided with between described base and valve body connector inwall and seal O shape and enclose, between valve stem connection and valve rod, be provided with sealing O shape circle; The described upper valve rod place of being rotationally connected is provided with removable seal filler portion.
Described sealing O shape circle is nitrile rubber.
Sliding bearing is provided with between described valve rod and valve body.
The beneficial effects of the utility model are:
One, left and right valve body to be linked into an integrated entity valve body by full weld, avoids and occurs that ball valve exposes the generation of phenomenon;
Two, be provided with between base and valve body connector inwall and seal O shape and enclose, sealing O shape circle is provided with between valve stem connection and valve rod, the valve rod upper end place of being rotationally connected is provided with removable seal filler portion, form multi-stage sealed protection, even if primary seal lost efficacy, still there is secondary seal to work on, effectively ensure that combustion gas is not revealed;
Three, spherome surface is provided with abrasion-resistance glass steel layer, reduces the rate of wear of ball valve, improves the working life of ball valve, reduces the frequency of part exchanging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 for base, 2 for sliding bearing, 3 for spheroid, 4 for left valve barrel, 5 for valve body connector, 6 for O shape circle, 8 for thrust bearing, 9 for right valve barrel, 10 for valve rod, 11 for valve stem connection, 12 for fixing bolt, 13 be stuffing box packing portion.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1, the full welded ball valve of directly buried type, it is characterized in that: comprise the valve body, base 1, valve body connector 5, valve rod 10, valve stem connection 11 and the spheroid 3 that are formed by connecting by left valve barrel 4 and right valve barrel 9, it is characterized in that: left and right valve body, an overall valve body is connected into by full weld with valve body connector 5, integrally-built valve body, effectively reduces the risk that combustion gas is revealed from gap, improves general safety performance.Valve rod is divided into upper valve rod and lower valve rod two parts, and upper valve body upper end is connected with switch, and lower end was communicated with valve stem connection and receives valve body, and the upper end place of being rotationally connected is provided with removable seal filler portion 13, is fixed by fixing bolt 12.Even if stuffing box packing portion 13 can ensure that gas sealing is not revealed when switch turns.Lower valve body upper end is connected to valve body by valve stem connection, and lower end connects base 1.Described spherome surface is provided with abrasion-resistance glass steel layer, is placed in valve body, and the rate of wear of ball valve can be reduced in wearing coat, improves the working life of ball valve, reduces the frequency of part exchanging, saves the cost of labor needed for renewal part.Be provided with between described base and valve body connector inwall and seal O shape and enclose, be provided with sealing O shape circle between valve stem connection and valve rod, many places arrange sealing O shape circle and can be formed multi-stage sealed, even if primary seal lost efficacy, secondary seal continuous firing, ensures that combustion gas can not be revealed.Be provided with sliding bearing 2 between valve rod and valve body, reduce valve rod and rotate the wearing and tearing produced.
Claims (3)
