2, the utility model realizes weighs automatically, and controllability is strong, precision is high, cut-out is timely.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model implementation is further described below in conjunction with attached drawing, following embodiment is descriptive, is not
Limited, protection scope of this utility model cannot be limited by this.
A kind of LNG steel cylinders automatic charging device, as shown in Figure 1, including LNG steel cylinders 10 and filling station 1, at the bottom of filling station
Pound 11 of weighing is installed under portion's support plate, the innovative point of the utility model is that control module 2 is equipped in the top of filling station,
Discharge duct 8 for emptying BOG (flash gas) gas in LNG steel cylinders is sequentially connected in series low temperature operated pneumatic valve c6 and shut-off valve b9
Connect afterwards with the exhaust nozzle of LNG steel cylinders, for for the liquid phase pipeline 7 of LNG cylinder fillings be sequentially connected in series low temperature operated pneumatic valve a4 and
It connect with the mouth that fills of LNG steel cylinders after shut-off valve a3, leads between the upstream and the downstream pipe of shut-off valve b of shut-off valve a
It crosses connecting pipe and low temperature operated pneumatic valve b5, the low temperature operated pneumatic valve a, low temperature operated pneumatic valve b and low temperature operated pneumatic valve c is installed
Control terminal connect with control module, its folding condition is controlled by control module, the pound of weighing is digital pound of weighing, and is claimed
The output end of weight pound is connect with control module, and module offer in order to control acts benchmark.
In the specific implementation of the utility model, in order to adapt to the deviation of numerous LNG steel cylinders placement positions in filling station,
Pipeline connection is effectively carried out, one section of rubber is mounted on the entrance pipe of shut-off valve a and on the export pipeline of shut-off valve b
Glue hose 12.
Operation principle
The LNG steel cylinders automatic charging device is made of gas phase pipeline, liquid phase pipeline and automatic charging device.This is filled automatically
The measuring principle of assembling device is that LNG steel cylinders are placed in filling station, is cylinder filling by liquid phase header road, is filling beforehand control
Module opens low temperature operated pneumatic valve c, and opens shut-off valve b manually, and the BOG gases being discharged in LNG steel cylinders are discharged into discharge duct,
LNG is just carried out after the completion of this process fills work.When starting to fill open shut-off valve a, while control module automatically open it is low
Wet movable valve a4, carries out cylinder filling at this time, and control module is filled according to the judgement of the output data of the pound of weighing constantly received
Dress state, when reaching setting weight or filling full, control module gives low temperature operated pneumatic valve one signal, closes low temperature at this time
Operated pneumatic valve a4, and shut-off valve a3 is turned off manually, low temperature operated pneumatic valve b is then opened by remaining residual liquid discharge in pipeline to exhaust
Pipeline, this process are completed to fill.
