Description

The rule of interlayer vaccum sealing stopper based on low temperature insulation container fill in composite construction
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.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 a are the schematic diagram of sealing-plug;Fig. 2 b are the schematic diagram of sealing material;Fig. 2 c are the schematic diagram of vacuum gauge;Figure 2d is the schematic diagram of tamponade;Fig. 2 e are the schematic diagram of plug;
In figure:Sealing-plug 1, vacuum gauge 2, the first O-ring 3, pressure release buffering ring 4, the second O-ring 5, tamponade 6, sealing tree Lipid layer 7, plug 8, third O-ring 9, the 4th O-ring 10.
Specific implementation mode
As shown in Figure 1 and Figure 2, include in the present embodiment:Sealing-plug 1, tamponade 6 and vacuum gauge 2, wherein:Vacuum gauge 2 Lower end embedding sealing plug 1 in, tamponade 6 is set between vacuum gauge 2 and sealing-plug 1.
The sealing-plug 1 is three-stage hollow structure, wherein including from bottom to top what three radiuses were sequentially increased successively Cavity.
The outside of the sealing-plug 1 is equipped with two groups of grooves and its corresponding O-ring 9,10.
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 It rises, is Δ P=Q/V=0.217Pa.Above-mentioned calculating is the result of calculation premised on helium, and Cryo Heat Insulation inner pressurd vessel is big It is used in gas, the main component of air is nitrogen and oxygen, their percent of pass by O-ring is less than helium, therefore presses and rise Above-mentioned calculated value will be less than.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the utility model principle and objective with Different modes carries out it local directed complete set, and the scope of protection of the utility model is subject to claims and not by above-mentioned specific Implementation is limited, and each implementation within its scope is by the constraint of the utility model.
