Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: seeing Fig. 1, a kind of liquefied natural gas sampler, including sampling tube 1, carburator, sampling container 3 and
Delivery pipe 4.Described carburator includes that gasifying pot 21, injection apparatus 22 and heater, described injection apparatus 22 are installed on vaporization
Tank 21 top, can be atomized liquefied natural gas by this injection apparatus 22.Described heater is for heating gasifying pot 21；
When being embodied as, described heater includes that one adds heat container, has at heating container content and adds deep fat, the submergence of described gasifying pot 21
Within adding deep fat, thus by the way of oil bath, liquefied natural gas is heated, it is possible to preferably gasifying pot 21 is heated.?
Gasifying pot 21 is provided with thermometer, can detect the temperature in gasifying pot 21 by this thermometer, in order to control heating-up temperature,
Thus quickly by liquefied natural gas gasifying.
The outlet of described sampling tube 1 is connected with the import of a three-way valve 5, and an outlet of this three-way valve 5 is by pipeline and spray
Injection device 22 is connected, and another outlet is connected with delivery pipe 4 by pipeline；By regulating three-way valve 5, it is possible to make sampling tube 1 with
Injection apparatus 22 turns on, or turns on delivery pipe 4.Pressurizer 10 it is provided with between three-way valve 5 and this injection apparatus 22；Logical
Cross pressurizer 10 and carry out supercharging, then by injection apparatus 22, the liquefied natural gas after supercharging is ejected in gasifying pot 21,
Efficiency and the speed of liquefied natural gas gasifying can be effectively increased.Quantitatively dress it is provided with between pressurizer 10 and injection apparatus 22
Put 11, with the volume of liquefied natural gas in control entrance gasifying pot 21, so that it is guaranteed that enter the liquefied natural gas energy of gasifying pot 21
Enough it is gasified totally.
The outlet of described gasifying pot 21 also is located at gasifying pot 21 top, and, the outlet of gasifying pot 21 is by pipeline simultaneously
Import and the import of sampling container 3 with delivery pipe 4 are connected, outlet the entering by pipeline and delivery pipe 4 of this sampling container 3
Mouthful being connected, wherein, the inlet and outlet of sampling container 3 lays respectively at the two ends of sampling container 3, being preferably exhausted and
