Description
Technical field
The utility model relates to pressure vessel more particularly to a kind of ozzles of the pressure vessel for oil vapor treatment.Belong to
Petrochemical industry.
Background technique
Currently, for oil vapor treatment pressure vessel manufacturing after, the water pressure test need to be carried out, to verify its pressure-containing parts
Intensity and sealing performance reliability.When test, reserved ozzle is generally first blocked.In general, first using pressure testing pipe cap and ozzle
Ozzle is blocked by the mode welded.After the completion of pressure testing, then pipe cap cut down.But the mode of this closure
It has the following deficiencies:
One, when welding due to ozzle and pressure testing pipe cap, it is not only easy to produce deformation and stress, moreover, welding heat affected
The chemical component in area also has burning phenomenon；
Two, when due to cutting pipe cap operation, it is also possible to ozzle can be damaged.
In order to solve above-mentioned these problems, in general, using the form for reinforcing forging or increasing the method for ozzle wall thickness, from whole
Reinforcement ozzle on body, when offsetting welding and cutting operation, to the adverse effect of ozzle.But due to forging and tubing
There are biggish differences for price, and larger due to material utilization amount, considerably increase the manufacturing cost of pressure vessel.Therefore, right
In the ozzle operating condition that large scale, particularly caliber are more than 100mm, the above method is very uneconomical practical.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide a kind of for oil gas
The ozzle of the pressure vessel of processing, it is easily manufactured, welding or cutting operation can not only be made to ozzle in the water pressure test
Ontology solves the strength problem of ozzle without directly affecting；It can also enough making pressure testing pipe cap in place in pressure vessel installation
Afterwards, then carry out live excision, greatly reduce technical difficulty, solve ozzle weld bond transport, be easy in installation process by
The problem of damage.
The purpose of this utility model is realized by the following technical solutions:
A kind of ozzle of the pressure vessel for oil vapor treatment, it is characterised in that: include: the pipe being reserved on pressure vessel
Mouth, the reinforcing ring being arranged on ozzle outer wall, the pressure testing pipe cap being fixed on reinforcing ring outer wall, wherein reinforcing ring is equipped with row
Stomata.
The diameter of the ozzle is the seamless steel pipe pipeline section greater than 100mm, and ozzle is equipped with weld bond.
The reinforcing ring is monolithic molding；The length of reinforcing ring is the seamless steel pipe pipeline section of 50mm, the thickness of reinforcing ring≤
1.05 times of ozzle wall thickness, and it is not more than 20mm；Clearance requirement≤1mm is bonded between reinforcing ring and ozzle outer wall；Reinforcing ring
Weld pitch ozzle weld bond distance be not less than 30mm.
The pressure testing pipe cap is oval butt-welded pipe cap, and the standard and wall thickness grade of pressure testing pipe cap are consistent with ozzle；And it tries
The overlapping length of the inner wall and reinforcing ring outer wall of pressure pipe cap is 10mm.
The diameter of the gas vent is in 6~10mm range；And one far from ozzle weld bond is arranged in reinforcing ring in gas vent
End, at 10~15mm of reinforcing ring edge.
The utility model has the beneficial effects that the utility model is due to the adoption of the above technical scheme, and it is easily manufactured, it can not only
Enough in the water pressure test, makes welding or cutting operation to nozzle body without directly affecting, solve the strength problem of ozzle；And
And, additionally it is possible to make pressure testing pipe cap after pressure vessel installation is in place, then carry out live excision, greatly reduce technical difficulty, solves
Ozzle weld bond of having determined is easy the problem of being damaged in transport, installation process.
Detailed description of the invention
