Abstract
The utility model relates to a kind of device, particularly a kind of gas cylinder vacuum-pumping density seal apparatus.It is characterized in that: vacuumizing to draw in valve has vacuum-pumping density blocking, and vacuum-pumping density blocking is connected with O type circle, vacuumizes and draws valve to be connected with vacuumizing joint by support, Quick Release Hoop, vacuumize and draw valve to be connected with vacuum-pumping tube.Owing to adopting technique scheme, the advantage that the utility model has and good effect are: be convenient to and the connection vacuumizing unit, can greatly enhance productivity, and sealing when can ensure shutoff, reduce because loading and unloading the leakage caused, the performance of product is significantly improved, and smaller and more exquisite uniqueness in shape.
Description
Technical field
The utility model relates to a kind of device, particularly a kind of gas cylinder vacuum-pumping density seal apparatus.
Background technique
At present, cryogenic insulated cylinder, also known as welded insulated gas cylinder, is the special welding gas cylinder for storing the low-temperature liquefaction natural-gas such as liquid oxygen, liquid nitrogen, liquid argon, LNG Liquefied natural gas.Cryogenic insulated cylinder formally can be designed to vertical and horizontal.Cryogenic insulated cylinder has the features such as safe and reliable, easy to use, charging ratio is high and can repeatedly fill, and has been used to alternative traditional Dewar vessel and high pressure steel gas bottle.Day by day increase along with to the demand of cryogenic insulated cylinder, more and more higher to the requirement of cryogenic insulated cylinder in heat-insulating property, loading technique and lossless storage, Daily boil-off-rate is low, and adding amount is large, and the cryogenic insulated cylinder grown memory time is more and more subject to the favor in market.Static evaporation rate is the important indicator weighing cryogenic insulated cylinder heat-insulating property, and the degree of vacuum of gas cylinder is directly connected to the static evaporation rate of gas cylinder.It is good again that the degree of vacuum of gas cylinder is taken out, if vacuum orifice shutoff poor sealing performance, so the retention time of degree of vacuum will shorten, and degree of vacuum is lost will be increased.And gas cylinder Ze Xufan factory vacuumizes again, this is both increasing the economic burden of user and enterprise virtually.The shortcoming one that prior art exists is that existing vacuum pumping device is connected complexity with unit of finding time, and sealing is poor, and productivity is low; Two is when dismantling shutoff without seal approach, leaks and cause degree of vacuum to reduce in dismounting shutoff process; Three is because being individual layer O shape coil structures after shutoff, and the probability that degree of vacuum is leaked is comparatively large, all brings a no small difficult problem to production process or later maintenance; Four is when repeating to vacuumize, and O shape circle is easy to wear.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of gas cylinder vacuum-pumping density seal apparatus, can improve to leak seriously existing evacuator is connected inconvenient, shutoff with unit of finding time time and degree of vacuum is held time the shortcoming such as short.
The utility model solves the technological scheme that its technical problem adopts: evacuator is designed to pinching quick disconnect connecter anatomical connectivity mouth, reduce the connection difficulty with unit of finding time, the sealability of whole cargo handling process is ensured by the position of drawing the pull bar of valve to move axially blocking, and sealing plug adopts double layer O-shaped coil structures, substantially increase vacuum-packed reliability, reduce the quality problems caused due to seal leakage, O shape circle groove design formula in the arc-shaped, reduce the wearing and tearing to O shape circle in pull bar drawing process, the last PVC＝polyvinyl chloride protective cover designing a kind of flange forms at evacuator mouth, proofing dust and protecting is carried out to evacuator.The utility model draws valve, vacuum-pumping density blocking, support, O type circle, vacuumizing joint, Quick Release Hoop, vacuum-pumping tube and capping to form by vacuumizing, it is characterized in that: vacuumizing to draw in valve has vacuum-pumping density blocking, vacuum-pumping density blocking is connected with O type circle, vacuumize and draw valve to be connected with vacuumizing joint by support, Quick Release Hoop, vacuumize and draw valve to be connected with vacuum-pumping tube.
Owing to adopting technique scheme, the advantage that the utility model has and good effect are: be convenient to and the connection vacuumizing unit, can greatly enhance productivity, and sealing when can ensure shutoff, reduce because loading and unloading the leakage caused, the performance of product is significantly improved, and smaller and more exquisite uniqueness in shape.
