Abstract
The invention discloses a filling and air return integrated LNG vehicle-mounted gas cylinder, and particularly relates to an improvement of the LNG gas cylinder. The filling and air return integrated LNG vehicle-mounted gas cylinder comprises a liquid adding air return opening, a tee joint pipe connected with the liquid adding air return opening, an air return hose and a liquid adding hose, wherein the air return hose and the liquid adding hose are connected with the tee joint pipe; and an air return valve is arranged at the middle portion, connected with the LNG vehicle-mounted gas cylinder, of the air return hose, and a liquid filling one-way valve is arranged at the middle portion, connected with the LNG vehicle-mounted gas cylinder, of the liquid adding hose. The structure of the filling and air return integrated LNG vehicle-mounted gas cylinder is changed, and a filling opening and the air return opening in the LNG vehicle-mounted gas cylinder are integrated through the tee joint pipe, so that natural gas return is carried out while natural gas filling is carried out, over-filling of the LNG vehicle-mounted gas cylinder is avoided, potential safety hazards caused by over-filling caused by manual operation are prevented, and the cost is reduced due to the fact that the air return opening is omitted.
Description
Technical field
The present invention relates to a kind of improvement of LNG gas cylinders, more particularly to a kind of filling return-air integrated form
LNG mounted gas cylinders.
Background technology
At present, LNG mounted gas cylinders are during natural gas charging, first by air filling gun and filling
Then return-air rifle is connected with gas returning port, then starts to fill natural gas, this aerating by mouth connection
Mode be in order to quickly fill LNG, but can exist and overcharge, cause the waste of LNG, also can
There is potential safety hazard.
The content of the invention
The technical problem to be solved is to provide a kind of new, anti-overcharge, structure letter
It is single, it is to avoid the filling return-air integrated form LNG mounted gas cylinders of potential safety hazard.
To solve above-mentioned technical problem, the technical solution used in the present invention is：
A kind of filling return-air integrated form LNG mounted gas cylinders, it is characterised in that：Including liquid feeding return-air
Mouthful, the tee pipe fitting being connected with liquid feeding gas returning port, and the return-air being connected with tee pipe fitting respectively
Flexible pipe, liquid feeding flexible pipe；The middle part that the return-air flexible pipe is connected with LNG mounted gas cylinders is provided with back
Air valve, the middle part that the return-air flexible pipe is connected with LNG mounted gas cylinders are provided with topping up check valve.
Using the beneficial effect produced by above-mentioned technical proposal it is：The present invention is from natural gas charging
Process is pinpointed the problems, and through professional's analysis, research, is changed from structure,
Filler, gas returning port are carried out by tee pipe fitting on LNG mounted gas cylinders integrated, made natural
When gas is filled when natural gas is filled return-air, LNG mounted gas cylinders is not overcharged, prevent artificial
Operation causes the potential safety hazard for overcharging, causing, and reduces cost because saving gas returning port part.
Description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is present invention filling return-air integrated morphology schematic diagram；
Wherein:1st, liquid feeding gas returning port；2nd, tee pipe fitting；3rd, return-air flexible pipe；4th, liquid feeding is soft
Pipe；5th, topping up check valve 6, return-air valve；7th, LNG mounted gas cylinders.
Specific embodiment
With reference to the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described, it is clear that described embodiment is only of the present invention
Divide embodiment, rather than the embodiment of whole.Based on the embodiment in the present invention, this area is general
The every other embodiment obtained under the premise of creative work is not made by logical technical staff,
Belong to the scope of protection of the invention.
Many details are elaborated in the following description in order to fully understand the present invention, but
It is that the present invention can also be different from alternate manner described here to implement using other, this area
Technical staff can be similar popularization, therefore the present invention in the case of without prejudice to intension of the present invention
Do not limited by following public specific embodiment.
As illustrated, the present invention is that will to fill return-air on LNG mounted gas cylinders 7 integrated, including
Liquid feeding gas returning port 1, the tee pipe fitting 2 being connected with liquid feeding gas returning port 1, and respectively with threeway
The return-air flexible pipe 3 of the connection of pipe fitting 2, liquid feeding flexible pipe 4；The return-air flexible pipe 3 is vehicle-mounted with LNG
The middle part of the connection of gas cylinder 7 is provided with return-air valve 6, the return-air flexible pipe 3 and LNG mounted gas cylinders
The middle part of 7 connections is provided with topping up check valve 5.
The present invention pinpoints the problems from natural gas charging process：Original aerating mode is in order to quickly fill
LNG, can exist and overcharge phenomenon, cause the waste of LNG, can also there is potential safety hazard, pass through
Professional's analysis, research, are changed from structure, will filling on LNG mounted gas cylinders
Mouthful, gas returning port carried out integrated by tee pipe fitting, make the side in natural gas charging fill natural gas
Side return-air, makes LNG mounted gas cylinders not overcharge, and prevents manual operation from causing to overcharge the peace for causing
Full hidden danger, reduces cost because saving gas returning port part.
