Abstract
The utility model discloses an on -vehicle gas cylinder of filling return -air integrated form LNG especially relates to the improvement of a LNG gas cylinder. The utility model discloses a liquid feeding return -air mouth, the tee bend pipe fitting of being connected with liquid feeding return -air mouth to and respectively with tee bend pipe connections's return -air hose, liquid feeding hose, the return -air hose is provided with the return -air valve with the middle part that the on -vehicle gas cylinder of LNG is connected, the return -air hose is equipped with the topping up check valve with the middle part that the on -vehicle gas cylinder of LNG is connected. The utility model discloses from structural the change, integrate filler, return -air mouth through the tee bend pipe fitting on the on -vehicle gas cylinder of LNG, make when the natural gas fills the dress limit fill dress natural gas limit return -air, the on -vehicle gas cylinder of messenger LNG can not crossed and fill, prevents that the manual operation from resulting in filling, and the potential safety hazard that leads to the fact makes cost reduction because of saving return -air mouth part.
Description
Technical field
The utility model relates to a kind of improvement of LNG gas cylinder, particularly relates to a kind of filling return-air integrated form LNG mounted gas cylinder.
Background technique
At present, air filling gun, in natural gas charging process, is first connected with filler by LNG mounted gas cylinder, then be connected with gas returning port by return-air rifle, then start to fill rock gas, this aerating mode is to fill LNG fast, but can exist and overcharge, cause the waste of LNG, also can there is potential safety hazard.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of novel, anti-overcharge, and structure is simple, avoids the filling return-air integrated form LNG mounted gas cylinder of potential safety hazard.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of filling return-air integrated form LNG mounted gas cylinder, is characterized in that: comprise liquid feeding gas returning port, the tee pipe fitting be connected with liquid feeding gas returning port, and the return-air flexible pipe be connected with tee pipe fitting respectively, liquid feeding flexible pipe; The middle part that described return-air flexible pipe is connected with LNG mounted gas cylinder is provided with return-air valve, and the middle part that described return-air flexible pipe is connected with LNG mounted gas cylinder is provided with topping up one-way valve.
The beneficial effect adopting technique scheme to produce is: the utility model is pinpointed the problems from natural gas charging process, and through professional workforce's analysis, research, change from structure, filler, gas returning port are undertaken integrated by tee pipe fitting by LNG mounted gas cylinder, make the limit when natural gas charging fill rock gas limit return-air, LNG mounted gas cylinder can not be overcharged, prevent manual operation from causing overcharging, the potential safety hazard caused, makes cost reduce because saving gas returning port part.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model filling return-air integrated morphology schematic diagram;
Wherein: 1, liquid feeding gas returning port; 2, tee pipe fitting; 3, return-air flexible pipe; 4, liquid feeding flexible pipe; 5, topping up one-way valve 6, return-air valve; 7, LNG mounted gas cylinder.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in the figure, the utility model is that return-air of annotating on LNG mounted gas cylinder 7 is integrated, comprises liquid feeding gas returning port 1, the tee pipe fitting 2 be connected with liquid feeding gas returning port 1, and the return-air flexible pipe 3, the liquid feeding flexible pipe 4 that are connected with tee pipe fitting 2 respectively; The middle part that described return-air flexible pipe 3 is connected with LNG mounted gas cylinder 7 is provided with return-air valve 6, and the middle part that described return-air flexible pipe 3 is connected with LNG mounted gas cylinder 7 is provided with topping up one-way valve 5.
The utility model is pinpointed the problems from natural gas charging process: original aerating mode is in order to fill LNG fast, can exist and overcharge phenomenon, cause the waste of LNG, also potential safety hazard can be there is, analyze through professional workforce, study, change from structure, filler, gas returning port are undertaken integrated by tee pipe fitting by LNG mounted gas cylinder, the limit when natural gas charging is made to fill rock gas limit return-air, LNG mounted gas cylinder can not be overcharged, preventing manual operation from causing overcharging the potential safety hazard caused, because saving gas returning port part, cost being reduced.
