According to an advantageous embodiment, in the low-temperature test platform of the utility model, height adjustment be it is controllable, especially
It is adjustable.
One Advantageous embodiments of the low-temperature test platform of the utility model are characterized in that the height adjustment is in storage container
It is so controllable or adjustable when decline, 1 meter is reduced within liquid level about 1 hour in the inspection container, wherein from container is examined
The time of middle decant(-ation) nitrogen is advantageously shortened, but the amount of the nitrogen evaporated suddenly is restricted to safe coefficient.
Another Advantageous embodiments of the low-temperature test platform of the utility model are characterized in that height adjustment is in storage container
It is so controllable or adjustable when rise, increase 1 meter within liquid level about 5 minutes in the inspection container, it is advantageously anti-herein
Only nitrogen filling examine container when splash so that not only the valve chest of regulating valve, there are also regulating valve driving mechanism and especially use
Cooled in the plug sleeve of supporting valve rod, this is undesirable.
According to an advantageous embodiment, processing is equipped on examining container in the low-temperature test platform of the utility model
Device heats the regulating valve after liquid nitrogen outflow by processing unit.One or more hair driers (Foen) or one
Or multiple heating flow sources may be used as processing unit.Twice thus the time between checkout procedure is shortened.
When the low-temperature test platform of the utility model is worked with liquid nitrogen, flexible steel in flat section tubing is preferably the soft of the super isolation of vacuum
Property transfer tube, as bought from Cryotherm GmbH&Co.KG Ji Xihaimu/Xi Ge company.
It is further advantageous that the connecting tube not only examine container on, also on storage container near bottom surface or the bottom of at
It is attached thereto in face, ensure that nitrogen is full of herein.
Also advantageously the inspection container and storage container are open containers in pressure seal meaning at this time.

Specific embodiment
Fig. 1 shows the low-temperature test mesa-shaped state for executing the inspection of regulating valve 2 herein, wherein regulating valve 2 is submerged into inspection
In liquid nitrogen in container 4, it is raised in this storage container 8 and is higher than the bottom surface for examining container 4.Examine container 4 and storage container 8
It is open container in pressure seal meaning.
Fig. 2 shows test ending and liquid nitrogen from examine container 4 flow out to storage container 8 after low-temperature test mesa-shaped state,
Wherein the storage container 8, which drops below, examines 4 bottom surface of container.
Figures 1 and 2 show that the low-temperature test platform of the utility model, here, liquid nitrogen is used as cooling medium.For adjusting
The low-temperature test platform of the low temperature functional ability test of valve 2 includes liquid nitrogen to be filled, fixed and has for regulating valve 2
Engaging mechanism 6 inspection container 4, engaging mechanism is located at below the liquid level examined in container 4, and low-temperature test platform further includes
Storage container 8 is connected to by flexible steel in flat section tubing 10 and examines container 4.Connecting tube 10 is not only storing on examining container, also
It is connected near bottom surface or in bottom surface on container.Flexible steel in flat section tubing 10 is the super isolation flexibility transfer of so-called vacuum
Pipe.
Storage container 8 is relative to inspection container 4 lower than the storage location for examining 4 bottom surface of container and higher than inspection container 4
Adjusted in a manner of height-adjustable between the filling position of bottom surface, wherein the height adjustment of storage container 8 by lifting platform or
Scissor-type lifting mechanism 12 is realized.
It is equipped with processing unit 14 on examining container 4, removes be attached to regulating valve 2 after the decline of storage container 8 whereby
On residual cryogenic liquid.One or more hair driers or one or more heating flow sources can be used as processing unit 14.
For low-temperature test platform operation, storage container 8 is placed into filling position first, so as to when inspection 4 quilt of container
The nitrogen will not flow out storage container 8 when filling nitrogen.Then, container is examined to be filled nitrogen by filling mechanism, until to be checked
The valve chest 16 for the regulating valve 2 tested is surrounded by nitrogen.When the valve chest 16 of regulating valve 2 is cooled and test ending, storage is held
Device 8 is placed into storage location, it is placed into the lower section for examining 4 bottom surface of container by elevating mechanism 12 on the position.When nitrogen from
When container 4 being examined to flow out to storage container 8 and execute primary new checkout procedure, storage container 8 is risen up by elevating mechanism 12
Higher than the filling position for examining 4 bottom surface of container, container 4 is examined thus to be filled automatically the nitrogen from storage container 8 and storage
Container 8 is drained.After checkout procedure terminates, the liquid nitrogen in container 4 is being examined to be discharged in storage container 8 again, way
It is that storage container 8 drops to the lower section for examining 4 bottom surface of container again.
Because examining container 4 should be rapidly again available as far as possible after a checkout procedure, therefore the height of storage container 8
Degree adjust be it is controllable, especially can so adjust, examine container in liquid level about 1 hour decline 1 meter.
In order to avoid regulating valve 2 and especially valve activator 18 and the plug sleeve of regulating valve 2 due to filling examine
Nitrogen when container 4 splash and caused by uncontrollable cooling, which can be controlled such or adjust when storage container 8 rises
It is whole, examining increase 1 meter within liquid level about 5 minutes in container.
The utility model be not limited to shown in embodiment.For example, low-temperature test platform is also suitble to following application, at this time
Low Temperature Liquid used should be replaced in the case where not having to dedicated pump after a checkout procedure in a manner of timesaving.
