Pipe sets measuring control valve and the second check valve, and air source control valve and measuring control valve are connected with controller, and this passes through gas
Source control valve and measuring control valve carry out corresponding break-make control to each pipeline respectively, so as to avoid because of one of magnetic valve
(i.e. air source control valve or measuring control valve) damages and overcharges or measure the failure such as inaccurate, the event of system in real work
Barrier rate can decline more than 33.3%.
2nd, this reduced form CNG filling machines only set air source control valve and the first check valve in aerating by-pass tube, and in aerating
Gun barrel sets measuring control valve and the second check valve, and this need not company of the tradition between each aerating by-pass tube and each aerating gun barrel
Connect and be respectively provided with magnetic valve, therefore the quantity that can reduce magnetic valve and check valve is used, so that simplify control device is to each magnetic valve (i.e. gas
Source control valve or measuring control valve) control.
3rd, this reduced form CNG filling machines set air source control valve and the first check valve in aerating by-pass tube, and in air filling gun
Pipe sets measuring control valve and the second check valve, so that each function is specially distinguished in filling machine, then staff couple event
The analysis of barrier problem solves to provide the foundation for becoming apparent from sentencing.
4th, the setting of air source control valve and measuring control valve can add using each type CNG in this reduced form CNG filling machines
Mechanism of qi, such as three line rush-harvesting and rush-planting types (i.e. three aerating by-pass tubes and two aerating gun barrels), (i.e. two aeratings point of two-wire rush-harvesting and rush-planting type
Manage and two aerating gun barrels on road), the gunlock type of three line four (i.e. three aerating by-pass tubes and four aerating gun barrels), the rifle of two-wire four (i.e.
