Description
Technical field
The present invention relates to a kind of link, particularly relate to pressurized container high strength stud.
Background technique
Pressurized container refers to filling gas or liquid, the Sealing Arrangement of carrying certain pressure.In order to more effectively implement scientific management and supervise inspection safely, according to working pressure, medium harmfulness and effect aborning thereof, pressurized container is divided three classes in China's " safety-supervision regulation of pressure vessel ".And to the pressurized container of each classification in design, manufacture process, and Interventions Requested, contents and mode have made different regulations.Pressurized container has implemented import safe mass licensing system, and import prohibited not obtain the commodity of import safety license certificate.Should divide according in up-to-date TSG R0004-2009 " fixed safe technology of pressure vessel Supervision Code ", first be divided into first group of medium and second group of medium by medium, and then divide classification I class according to pressure and volume, II class, III class, the so-called first kind of old content regulation, Equations of The Second Kind, the 3rd class are inapplicable.Pressurized container will carry out pressure test (generally carrying out the hydrostatic test).Nondestructive inspection selective examination or all welding inspections are carried out to principal weld.But, non-flammable very low to pressure or container that is nontoxic, non-corrosiveness medium, if do not find defect, after obtaining certain use experience, can not make nondestructive flaw detection examination.In the complete examination cycle of container, be generally every 6 years and at least carry out once.To the manufacture accepted container of splendid attire air and inert gas, obtain use experience and twice inside and outside inspection confirm corrosion-free after, the complete examination cycle can proper extension.So the stud that pressurized container uses is necessary for high strength stud, the stud of existing market all can not meet the usage requirement of pressurized container, so there is deficiency.
In sum, for the defect of prior art, need pressurized container high strength stud especially, to solve the deficiencies in the prior art.
Summary of the invention
For in prior art to the deficiency that the stud of pressurized container in use exists, and bringing very large inconvenience in the work of reality, the present invention proposes pressurized container high strength stud, novel in design, can be used in above pressurized container, address the deficiencies of the prior art.
To achieve these goals, the present invention realizes by the following technical solutions:
Pressurized container high strength stud, comprise stud body, this material of stopping employing of stud is alloyed steel, the diameter of stud body is 100mm, the inside of stud body is hollow structure, the outer surface of stud body is provided with outside thread, and the internal surface of stud body is provided with internal thread, and the top of stud body is provided with tapping scaffold.
Further, the centre of described tapping scaffold is provided with sleeve, and the diameter of sleeve is identical with the diameter of stud body.
Further, detachable connection is adopted between described tapping scaffold and stud body.
Further, the length of described stud body is 600mm.
The invention has the beneficial effects as follows: this product structure is simple, easy to make, stud is high strength, can be applied to above pressurized container, and guarantees pressurized container safety in use, ensure that pressurized container safety in use, and be convenient to assembling, practicability is excellent, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is pressurized container high strength bolt structure schematic diagram of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
See Fig. 1, pressurized container high strength stud, comprise stud body 100, it is alloyed steel that stud 100 stops the material adopted, the diameter of stud body 100 is 100mm, the inside of stud body 100 is hollow structure, the outer surface of stud body 100 is provided with outside thread 110, the internal surface of stud body 100 is provided with internal thread 120, the top of stud body 100 is provided with tapping scaffold 130, the centre of tapping scaffold 130 is provided with sleeve 140, the diameter of sleeve 140 is identical with the diameter of stud body 100, detachable connection is adopted between tapping scaffold 130 and stud body 100.The length of stud body 100 is 600mm.
The present invention is effective is: structure is simple, easy to make, stud is high strength, can be applied to above pressurized container, and guarantees pressurized container safety in use, ensure that pressurized container safety in use, and be convenient to assembling, practicability is excellent, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
