Abstract
The utility model provides a valve body hard seal build-up welding structure comprising a left valve body, a right valve body and a bolt, wherein the right valve body is opposite to the left valve body, the bolt is used for assembling the left valve body and the right valve body together, and the left valve body and the right valve body form a cavity after being assembled together. The valve body hard seal build-up welding structure of the utility model is realized by directly forming the hard seal on the valve body via the build-up welding technology, and the conception of sealing a valve seat in the conventional sense is omitted.
Description
Technical field
The utility model relates to the sealed valve technology, relates in particular to the hard sealed reactor welding structure of a kind of novel valve body.
Background technique
The major function of ball valve is to cut off or connect ducted fluid passage.The working principle of ball valve is to apply certain torque by drive unit in the valve rod upper end to pass to spheroid, makes its half-twist, accomplishes the action of unlatching or throttle down.The sealing principle of ball seat is according to its structure and different, and valve seat construction commonly used can be divided into fixed valve base fixedly spheroid two class greatly of spheroid and floating valve seat of floating.When valve seat when fixedly spheroid floats; Produce displacement at the fluid pressure action lower sphere at fluid flow direction; It is more closely contacted with the sealing of valve rear valve base, and promptly the specific pressure on the sealing face increases, and forms the single face sealing; Corresponding the reducing of specific pressure on the sealing surface of seat before the valve often do not guarantee sealing simultaneously.
More and more become the main flow in market along with the manufacturing continuous development hard seal ball valve of valve.It can be operated in than under the more harsh operating mode of general soft seal valve.The development of keyed floating ball valve has also progressively got into the hard sealing epoch.As existing floating ball hard seal ball valve in the market basically all is to lean on valve seat built-up welding hard sealing configuration to form.
The model utility content
The creator of the utility model has developed a kind of novel hard sealing floating ball valve after having analyzed above-mentioned reason.Particularly, the hard sealed reactor welding structure of the valve body of the utility model directly on valve body built-up welding hard sealing realize, saved the notion of conventional meaning upper sealing valve seat.In addition, the utility model also is applied to assembling with bolt arrangement, has so both solved an assembling difficult problem, has guaranteed the sealing effect that valve is good again.
Particularly, the utility model provides a kind of valve body hard sealed reactor welding structure, comprising:
Left side body valve body;
Right body valve body is relative with said left body valve body; And
Bolt is assembled together said left body valve body and said right body valve body,
Wherein, said left body valve body and said right body valve body form a cavity after assembling.
According to a preferred embodiment of the utility model, in the hard sealed reactor welding structure of above-mentioned valve body, the sealing surface place built-up welding of the inboard of said left body valve body has hard alloy piece.
According to a preferred embodiment of the utility model, in the hard sealed reactor welding structure of above-mentioned valve body, also comprise:
Ball valve is arranged in said left body valve body and the formed cavity of said right body valve body.
According to a preferred embodiment of the utility model, in the hard sealed reactor welding structure of above-mentioned valve body, also comprise:
Right body spring valve seat is installed in the said right body valve body.
According to a preferred embodiment of the utility model, in the hard sealed reactor welding structure of above-mentioned valve body, said right body spring valve seat contacts with said ball valve and said ball valve is pushed to the hard alloy piece of said left body valve body.
Should be appreciated that the above generality of the utility model is described and following detailed description all is exemplary and illustrative, and be intended to further explanation is provided for as claimed in claim the utility model.
Description of drawings
Accompanying drawing mainly is to be used to provide the utility model is further understood.Accompanying drawing shows the embodiment of the utility model, and plays the effect of explaining the utility model principle with this specification.In the accompanying drawing:
Fig. 1 schematically shows the structural drawing according to the hard sealed reactor welding structure of valve body of the utility model.
Embodiment
Describe the technological scheme of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 schematically shows the structural drawing according to the hard sealed reactor welding structure of valve body of the utility model.In the embodiment shown in fig. 1, the hard sealed reactor welding structure 100 of the valve body of the utility model mainly comprises: left body valve body 101, right body valve body 102 and bolt 103.
Wherein, right body valve body 102 is relative with said left body valve body 101.Bolt 103 is assembled together said left body valve body 101 with said right body valve body 102, so that said left body valve body 101 forms a cavity with said right body valve body 102 after assembling.This cavity can be used for holding the spheroid of ball valve.Therefore, this cavity need cooperate with the face seal of this spheroid.
Particularly, according to a preferred embodiment of the utility model, in the hard sealed reactor welding structure 100 of above-mentioned valve body, the sealing surface place built-up welding of the inboard of said left body valve body 101 has hard alloy piece 104.
As stated, ball valve 105 will be set in said left body valve body 101 and the said right body valve body 102 formed cavitys.This cavity cooperates with the face seal of the spheroid of this ball valve 105.
In addition, according to a preferred embodiment of the utility model, in the hard sealed reactor welding structure 101 of above-mentioned valve body, can also comprise a right body spring valve seat 106.This right side body spring valve seat 106 can be installed in the said right body valve body 102.According to another optional embodiment of the utility model, also a left body spring valve seat can be set in left body valve body 101 in a similar fashion, to realize the similar techniques effect.
In the assembly process of the product of the utility model,, and grind with the spheroid of ball valve at first at the above-mentioned hard alloy piece 104 of sealing surface place built-up welding of the inboard of left body valve body 101.After the completion, with the right body spring valve seat 106 right body valve body 102 of packing into, and the spheroid of the ball valve of packing into, at last left body valve body 101 and the right body valve body of right body 102 bolts are linked and packed, and then accomplish the sealing assembling work of valve.
The hard sealed reactor welding structure 100 of the valve body of the utility model is when work; Valve can be pushed the spheroid of ball valve 105 to the hard alloy piece 104 of sealing surface of the inboard of above-mentioned left body valve body 101 tightly through right body spring valve seat 106, thereby forms the one-way sealing effect.
To sum up, the directly built-up welding hard sealing realization on valve body of the hard sealed reactor welding structure of the valve body of the utility model, thereby can save conventional meaning upper sealing valve seat.On the other hand, the utility model also is applied to assembling with bolt arrangement, has so both solved an assembling difficult problem, has guaranteed the sealing effect that valve is good again.
The foregoing description provides to those of ordinary skills and realizes or use the utility model; Those of ordinary skills can be under the situation of the model utility thought that does not break away from the utility model; The foregoing description is made various modifications or variation; Thereby the protection domain of the utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
