The liquid of phase pipeline is filtered.It has the following disadvantages: that (1) filter hole is easily clogged with impurities using filter mantle filtering, is easy
It causes liquidometer display inaccuracy or without display, filter hole has been opened greatly and filter effect is not achieved；(2) after long-time use,
Impurity can be accumulated in filter mantle, influence the use of liquidometer；(3) liner is when doing hydraulic pressure test, not into the water in filter mantle
It is easy to be discharged, is easy for that ice is caused to block up phenomenon so in actual use, so that liquidometer be made not to be available.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of vacuum that differential pressure levelmeter thereon can be used reliably will be provided
It is insulated deep cooling pressure vessel.
To solve the above-mentioned problems, the technical scheme adopted by the invention is as follows: a kind of vacuum insulation deep cooling pressure vessel, packet

Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of vacuum insulation deep cooling pressure vessel of the present invention.
Specific embodiment
The present invention is described in further detail with attached drawing combined with specific embodiments below.
As shown in Figure 1, a kind of vacuum insulation deep cooling pressure vessel, comprising: liner 2 and shell 1, liner 2 are installed on shell 1
In, it is provided with vacuum heat-insulating layer between liner 2 and shell 1, the difference for detecting liquid level in liner 2 is provided on the outside of shell 1
Liquidometer 3 is pressed, the liquid phase entrance 31 of differential pressure levelmeter 3 passes through shell 1 by liquid phase pipeline 32 and is connected with the bottom of liner 2,
The gas phase entrance 33 of differential pressure levelmeter 3 passes through shell 1 by gas phase pipeline 34 and is connected with the top of liner 2, in liner 2
It is provided with a U-bend 4, U-bend 4 is arranged in the form of entrance and exit is directed downwardly, the outlet and liquid phase of U-bend 4
Pipeline 32 is connected with the entrance of 2 connectivity part of liner, and the inlet of U-bend 4 is provided with 45 degree of oblique angles, and U-bend is arranged
Impurity after pipe 4 in liner 2 can be because the relationship of self weight just can not cross the top of U-bend 4 and enter liquid phase pipeline 32
