Description
Technical field
This utility model is related to liquefied petroleum gas cylinder experimental technique field, more particularly, to a kind of intelligent rotating disc type liquefaction
Petroleum gas steel bottle water pressure test quick detection line.
Background technology
The iso4706-1-2008 " repeatable fill welding steel cylinder " that International Organization for Standardization formulates, the Chinese government formulates
Gb5842-2006 " liquefied petroleum gas steel cylinder ", gb8334-2011 " liquefied petroleum gas steel cylinder periodic inspection and evaluation ", gb/
T9251-2011 " gas cylinder by hydrostatic pressure test method ", and special safety equipment technical specification tsg r0006-2014 " gas cylinder safely
Technology Supervision Code " etc. standard all specify that the either exfactory inspection of liquefied petroleum gas steel cylinder or periodic inspection all must do water
" by only detecting " of pressure test, but in production practices, these standards are not executed.
Studying carefully its topmost reason is mostly current international, domestic production water pressure test testing equipment is single device, real
Now not continuous detecting it is impossible to be adapted with steel cylinder production status.As China at present medium scale steel cylinder manufacturer one
The class's yield of bar production line is in 2000 bottles about/per tour, and mostly existing hydraulic pressure testing equipment is single device, every steel cylinder
Checkout procedure include bottle, water filling, pressurization, aerofluxuss, repressurization, observation, judgement, record, discharge water, the action such as lower bottle, the time is extremely
Few 5 minutes, at most check 12 steel cylinders per hour, calculated by 8 hours, per tour can only detect 96 steel cylinders, much meet not
The requirement of " by only checking ".
Although domestic and international relevant enterprise, industry specialists and scholar have carried out substantial amounts of research and discovery, up to the present,
Existing water pressure test testing equipment all fails to reach the requirement of steel cylinder production line actual production, is mainly manifested in following side
Face:
1) detection speed does not reach requirement.As it was previously stated, mostly existing hydraulic pressure testing equipment is single device, every steel cylinder
About 5 minutes Check-Out Times, at most check 12 steel cylinders per hour, calculated by 8 hours, per tour can only detect 96 steel
Bottle, much can not meet steel cylinder manufacturer a production line class's yield 2000 bottles about/per tour requirement.
2) accuracy of detection is difficult to ensure that.The indicator that current detection method relies primarily on human eye observation's pointer pressure becomes
Whether qualified change amount is to differentiate steel cylinder, due to the impact of human-body fatigue degree, and the restriction of naked eyes diversity, 1500- to be met
The requirement of 2000 bottles/per tour production yields, and remain that accurate observation is difficult to accomplish.
3) bottle extra stress during the water pressure test.During the water pressure test at present, the seal form of steel cylinder is all close using bottleneck pressure
Envelope mode, this pressure inevitably acts on bottle that is to say, that bottle is in addition to by test pressure during the water pressure test
Also receive extra active force, therefore test data can not correctly reflect the actual pressure situation of steel cylinder.
Based on above reason, the water pressure test " by only detecting " that steel cylinder manufacturer has to national standard to require is flexible
Do not detect for " sampling Detection " or, cause a large amount of not social through the steel cylinder inflow of the water pressure test, this is just blast thing
Therefore leave great hidden danger.
