Description
Technical field
The utility model relates to a kind of technology in vaccum sealing stopper field, it is specifically a kind of for vehicle-mounted LNG bottle with
The rule plug of the interlayer vaccum sealing stopper based on low temperature insulation container of detection and the monitoring of the laminated vacuum of industrial Dewar bottle is multiple
Close structure.
Background technology
Vacuum insulation deep freeze refrigeration plant needs to measure the layer vacuum of low-temperature heat-insulation pressure container in production, and
And it needed to carry out periodic detection every 1 year or 3 years.Currently, as large-scale storage tank only reaches 0.001Tor equipped with highest vacuum range
Vacuum gauge, layer vacuum can be detected in real time, even if not reaching the vacuum level requirements of professional standard, in practical applications
The reference that whether can still fail as laminated vacuum.And vehicle-mounted LNG gas cylinders and industrial Dewar bottle are then not equipped with vacuum gauge
Pipe, when factory testing, can only measure the dynamic vacuum degree for the evacuation pipeline that interlayer evacuates outside mouth, due to pipeline outgassing rate with
The reason of outgassing rate is compared inside interlayer, and size be can not ignore, so permanent vacuum in true interlayer can not be detected
Degree.
Utility model content
The utility model is directed to deficiencies of the prior art, proposes that a kind of interlayer based on low temperature insulation container is taken out
The rule of empty sealing-plug fill in composite construction, can reach extremely low glomus mosseae, convenient to monitor vacuum degree in bottle intraformational bed at any time.
The utility model is achieved through the following technical solutions:
The utility model includes:Sealing-plug, tamponade and the vacuum gauge being socketed successively from outside to inside, wherein:Vacuum gauge
Lower end embedding sealing plug in, be tightly connected between tamponade and sealing-plug.
The sealing-plug is three-stage hollow structure, wherein including from bottom to top the sky that three radiuses are sequentially increased successively
The probe of chamber, the vacuum gauge is located in middle cavity.
At least one set of sealing mechanism is equipped between the vacuum gauge and tamponade, which includes that a pressure release is slow
Rush ring and a pair of of O-ring positioned at its both sides.
The outside of the sealing-plug is equipped at least one set of groove and its corresponding O-ring.
Technique effect
Compared with prior art, the utility model is compound by vacuum gauge in the case where not changing original gas cylinder structure
To the center of the interlayer vaccum sealing stopper of low temperature insulation container, the rule plug composite construction of the utility model is formed, can be supervised at any time
Depending on the vacuum degree in interlayer, the cost of layer vacuum periodic detection is saved, improves industry operational efficiency.

6 outside of tamponade is equipped with screw thread.
The upper end of the vacuum gauge 2 is equipped with plug 8, which is embedded in tamponade 6 and its input terminal and vacuum gauge
2 output end is connected.
Sealing resin layer 7 is equipped between the tamponade 6 and vacuum gauge 2;Between the sealing-plug 1 and tamponade 6
Equipped with sealing resin layer 7.
There are one being set from top to down between the position and tamponade 6 of the middle cavity of the 2 embedding sealing plug 1 of vacuum gauge
The first pressure release buffering ring 4 of O-ring 3, one and second O-ring 5.
The present apparatus be completed after using helium mass spectrometer leak detector carry out leak rate detection, leak rate calculation be Qt=
5.5*10-11Pa·m3/ s, when wherein time T=157680000 seconds after 5 years, then total air leakage Q=Qt× T=
0.0867Pa·m3,
When interlayer volume is 40L, i.e. V=0.04m3, then the pressure value added of layer vacuum is properly termed as pressing after 5 years
