Researchist finds, prior art is low relative to blue gas cost, cost is low, conveniently moving, and range of use is large, saves cost over half than blue gas.
Concrete scheme of the present utility model is:
A kind of Small Civil CNG regulator, comprise the CNG compression bottle that the capacity be connected by pipeline is 10 ~ 25 cubes successively, the automobile-used pressure reducer of CNG and civilian reducing valve, the pipeline between described CNG compression bottle and automobile regulator is made up of vapour vehicle CNG pipe.
Also comprise gas meter, described gas meter is placed in described civilian reducing valve rear end.
Described outer diameter tube is less than 2cm.
The bottle neck of described CNG compression bottle is provided with air valve, and described air valve is three-way air valve.
Described pipeline is provided with pressure display meter.
A kind of mobile fuel gas bottle transportation device, for laying Small Civil CNG regulator, comprise walking dolly, dolly is provided with CNG compression bottle support.
Further in use, dolly is also installed the car cover of the automobile-used pressure reducer of CNG, car cover is iron and steel cover, and its purposes mainly protects the automobile-used pressure reducer of CNG, and civilian reducing valve is placed in outside car cover.
The beneficial effects of the utility model are:
(1) compared to blue gas and common natural fuels, cost is low;
(2) and walking dolly combine, realize quick detach fast-assembling, be convenient to isolated user to the civilian use of CNG technology and the replacing of equipment;
(3) reorganize and outfit structure relatively simple, do not have complicated connection in series-parallel structure, little, the shared space of overall volume is little.

Detailed description of the invention
Embodiment: a kind of Small Civil CNG regulator, see Fig. 1 to Fig. 6, comprising the capacity be connected by pipeline is successively that the automobile-used pressure reducer of CNG compression bottle 1, CNG 2 of 10 ~ 25 cubes and the pipeline between civilian reducing valve 10, CNG compression bottle 1 and the automobile-used pressure reducer 2 of CNG are made up of vapour vehicle CNG pipe.
Also comprise gas meter, gas meter is placed in civilian reducing valve rear end, Real-Time Monitoring flow.By liaison of penstock gas metering table, the quantity that user uses can be tested out.
In the present embodiment, outer diameter tube is 1cm.Bear about 1.5 times that pressure is 230Kg.
The bottle neck of CNG compression bottle is provided with air valve 3, air valve 3 is three-way air valve.During use, can inflate, also can exit.Three-way valve, can be directly related on steel cylinder, and after can charging gas again, threeway is removed by quick coupling forever.
Road is provided with pressure display meter 11, can Real-Time Monitoring pipeline pressure, ensures safety.
A kind of mobile fuel gas bottle transportation device, for laying Small Civil CNG regulator, comprise walking dolly, dolly is provided with CNG compression bottle support.
Further in use, dolly vehicle body 7 is also installed the car cover of the automobile-used pressure reducer of CNG, car cover is iron and steel cover, and its purposes mainly protects the automobile-used pressure reducer of CNG, and civilian reducing valve is placed in outside car cover.
