Row finishing causes processing cost higher.
Utility model content
To solve the above problems, the utility model provides the low Nuclear piping of a kind of good sealing effect, processing cost with not
Become rusty steel flange, and concrete technical scheme is：
Nuclear piping steel flange, including public law is blue, mother law is blue and sealing ring, the public law is blue to close with mother law orchid
Together, it is blue between mother law orchid to be located at public law for the sealing ring；The public law is blue to be provided with hold-down column with the blue relative end face of mother law
And sealing column, the hold-down column are located at the blue center of public law, hold-down column and sealing column are higher by the blue end face of public law, hold-down column
Center is provided with through hole；The blue center of the mother law is provided with through hole, mother law it is blue with the blue relative end face of public law provided with cone shaped countersink and
Hold-down ring, the cone shaped countersink and through hole are concentric, and the hold-down ring is higher by the blue end face of mother law, and hold-down ring is provided with sealing
Groove, the seal groove is built with sealing ring；One end of the sealing ring is provided with the conical surface, and seal ring set is in the blue hold-down column of public law
On, the conical surface is combined with cone shaped countersink, and the sealing column is pressed on hold-down ring, and sealing column compresses sealing ring.
Preferably, the blue end face of the public law is provided with delta seal ring, and the delta seal ring is inserted into sealing ring.
Preferably, the end face of the sealing column is provided with V-shaped groove.
Sealing ring is using the softer brass of material, and public law is blue and mother law orchid uses stainless steel, and public law is blue, mother law is blue and close
The complete use of seal ring.
Cone shaped countersink is engaged with the conical surface of sealing ring, good airproof performance, and mother law orchid cone shaped countersink can be reduced using brass
Machining accuracy, brass material is soft, yielding, blue and mother law is blue mutually compresses by public law, makes the conical surface and the taper of sealing ring
Counterbore is fitted close.Delta seal ring on public law orchid squeezes into sealing ring in the presence of thrust, makes public law orchid and sealing ring
It is fitted close.
Hold-down column cooperates with hold-down ring and compresses sealing ring, further prevents from revealing.Hold-down column contacts with sealing ring
Face be provided with V-shaped groove, V-shaped groove can further improve the contact area of hold-down column and sealing ring, improve sealing effectiveness.Hold-down column and
The time finished is reduced in the end face that hold-down ring is higher by flange body, reduces processing cost.
The utility model has the advantages that compared with prior art：
Nuclear piping provided by the utility model steel flange good airproof performance, easy to process, processing cost is low.
Brief description of the drawings
Fig. 1 is assembling section of the present utility model；
Fig. 2 is the blue cross-sectional view of public law；
Fig. 3 is the cross-sectional view of sealing ring.
Embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, Nuclear piping steel flange, including public law orchid 1, mother law orchid 2 and sealing ring 4, it is described
Together with public law orchid 1 is 2-in-1 with mother law orchid, the sealing ring 4 is located between public law orchid 1 and mother law orchid 2.The public law orchid 1 and mother
