Description
Technical field
The utility model relates to the production field of liquefied natural gas bottle, is specifically related to a kind of liquefied natural gas bottle inner bag detection cubing.
Background technology
Liquefied natural gas (LNG) (LNG) gas cylinder carries out carrying for splendid attire liquefied natural gas (LNG) or directly provides the gas cylinder of fuel for vehicle.Liquefied natural gas bottle is made up of inside and outside courage and other annexes, needs after mounting to detect the bearing capacity of gas cylinder and sealing.During traditional detection, that employing one soft rubber band is around on the sidewall of divider, then by fixture, soft rubber band is gripped, thus shutoff is carried out to the aperture that distributor side wall is offered, then in gas cylinder, pass into pressure gas from the aperture distributor tip end surface or it is vacuumized, checking sealing and the bearing capacity of gas cylinder with this.But when adopting such scheme to implement, be difficult to ensure that soft rubber band can carry out reliable shutoff to the aperture in distributor side wall, when particularly vacuumizing sucking-off gas detect gas cylinder sealing property outside gas cylinder.
Utility model content
The purpose of this utility model is to provide a kind of liquefied natural gas bottle inner bag detection cubing, and it can ensure to detect reliably cylinder liner sealing, improves the reliability of cylinder liner sealing propertytest.
For achieving the above object, the utility model have employed following technical scheme and operates:
A kind of liquefied natural gas bottle inner bag detection cubing, it is characterized in that: comprise a seal closure and sealing shroud, the cover top of seal closure arranges the pipe adapter for connecting leak detection assembly, sealing shroud is set in the periphery of seal closure and forms the cooperation that is threaded between the two, divider is plugged in seal closure and sealing shroud is inner, sealing shroud is by first, two pipeline sections are formed and the internal diameter of the first pipeline section is greater than the internal diameter of the second pipeline section, seal closure is plugged in the first pipeline section, first, the table top inner ring at the two pipeline section places of joining is provided with elastic seal ring, seal closure end end face compresses elastic seal ring generation deformation to the sealing gap between distributor side wall and the second pipeline section inwall.
Concrete scheme is: the table top of sealing shroud is provided with the O-ring seal installing ring being set in divider periphery, and O-ring seal installing ring arranges the annular vacancy portion for installing elastic seal ring near the inner ring place of the end end face of seal closure side.The internal diameter of seal closure, O-ring seal installing ring, the second pipeline section three is consistent.Elastic seal ring is O-ring seals.Seal closure is that 304 steel are made, and O-ring seal installing ring, sealing shroud are that brass is made.
The liquefied natural gas bottle inner bag detection cubing that technique scheme provides, it effectively can solve traditional cubing to problem poorly sealed during cylinder liner air-leakage test, improves Detection results and precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model using state schematic diagram.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with example, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technical scheme that the utility model is taked is as Fig. 1, shown in 2, a kind of liquefied natural gas bottle inner bag detection cubing, comprise a seal closure 11 and sealing shroud 12, the cover top of seal closure 11 arranges the pipe adapter 111 for connecting air-blowing assembly, sealing shroud 12 is set in the periphery of seal closure 11 and forms the cooperation that is threaded between the two, divider 20 is plugged in seal closure 11 and sealing shroud 12 is inner, sealing shroud 12 is by first, two pipeline sections are formed and the internal diameter of the first pipeline section 12a is greater than the internal diameter of the second pipeline section 12b, seal closure 11 is plugged in the first pipeline section 12a, first, the table top 12c inner ring at the two pipeline section places of joining is provided with elastic seal ring 13, seal closure 11 end end face compresses elastic seal ring 13 and deformation occurs to the sealing gap between divider 20 sidewall and the second pipeline section 12b inwall.In use, make in the inner chamber all between the first pipeline section 12a and seal closure 11 of aperture on divider 20 sidewall, deformation is there is thus to the sealing gap between divider 20 sidewall and the second pipeline section 12b inwall like this by seal closure 11 end end face compressing elastic seal ring 13, thus sealing when ensureing inflation, the sealing of cylinder liner is detected reliably.The periphery that sealing shroud 12 is set in seal closure 11 forms and to be threaded cooperation, that is arranges external thread on the outer peripheral face of seal closure 11, and the inwall of the first pipeline section 12a arranges internal thread, forms detachablely to be connected cooperation between seal closure with sealing shroud.
When concrete operations, can arrange the O-ring seal installing ring 14 that is set in divider 20 periphery on the table top 12c of sealing shroud 12, O-ring seal installing ring 14 arranges the annular vacancy portion for installing elastic seal ring 13 near the inner ring place of the end end face of seal closure 11 side.So more be conducive to the installation of elastic seal ring 13 on sealing shroud 12.What preferably arranged by the internal diameter of seal closure 11, O-ring seal installing ring 14, second pipeline section 12b three during concrete operations is consistent, ensures that elastic seal ring 13 can effectively seal after being out of shape.During practical operation, the external diameter of divider 20 is 75mm, and the internal diameter of seal closure 11, O-ring seal installing ring 14, second pipeline section 12b three is all set to 75.5mm.Elastic seal ring 13 can be O-ring seals, and seal closure 11 is that 304 steel are made, and O-ring seal installing ring 14, sealing shroud 12 are made for brass, ensures the reliability of sealing and extends the serviceable life of cubing.
In a word, the liquefied natural gas bottle inner bag detection cubing that the utility model provides, it effectively can solve traditional cubing to problem poorly sealed during cylinder liner air-leakage test, improves Detection results and the precision of cylinder liner.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
