Description
Technical field
The utility model relates to natural gas equipment technical field, refers to a kind of filling sequence control cabinet especially.
Background technique
CNG Filling Station (i.e. CNG gas station) or L-CNG (i.e. liquified natural gas) build station jointly all to be needed to distribute air cylinder group pressure, to improve aerating efficiency, energy-saving and emission-reduction.But at present mainly by manual allocation air cylinder group pressure, automatically cannot distribute air cylinder group pressure, therefore a kind of device of automatic distribution air cylinder group pressure is problem demanding prompt solution.
Model utility content
The utility model proposes a kind of filling sequence control cabinet, solve the problem automatically cannot distributing air cylinder group pressure in prior art.
Filling sequence control cabinet of the present utility model, comprise: cabinet and be positioned at the suction tude of cabinet, the first gas tube, the second gas tube and the 3rd gas tube, every bar pipeline is provided with switch valve, 3rd gas tube is communicated with described suction tude, and described first gas tube is communicated with described suction tude with the second sequence valve respectively by the first sequence valve with the second gas tube.
Wherein, described cabinet is also provided with the first pressure gauge, the second pressure gauge and the 3rd pressure gauge, described first pressure gauge, the second pressure gauge are connected described first gas tube, the second gas tube and the 3rd gas tube with the 3rd pressure gauge respectively by the first arm, the second arm and the 3rd arm.
Wherein, described first gas tube, the second gas tube and the 3rd gas tube are provided with one-way valve.
Wherein, cabinet is also provided with fixed support, described suction tude, the first gas tube, the second gas tube and the 3rd gas tube are fixed on described cabinet by described fixed support.
Filling sequence control cabinet of the present utility model by arranging sequence valve respectively on the first gas tube and the second gas tube, the pressure of sequence valve is regulated when inflating, thus achieve distribution air cylinder pressure automatically, the function of sequential inflation is carried out by senior middle school's low pressure air cylinder.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

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 the utility model part embodiment, 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.
The filling sequence control cabinet of the present embodiment as shown in Figures 1 to 3, comprising: cabinet 1 and be arranged in suction tude 2, first gas tube 31 (low inflation pipe) of cabinet 1, the second gas tube 32 (pressure gas tube) and the 3rd gas tube 33 (high-pressure aerated pipe).Every bar pipeline is provided with switch valve 4, and the 3rd gas tube 33 is communicated with described suction tude 2.First gas tube 31 is communicated with suction tude 2 with the second sequence valve 52 respectively by the first sequence valve 51 with the second gas tube 32.
The filling sequence control cabinet of the present embodiment by arranging sequence valve respectively on the first gas tube 31 and the second gas tube 32, the pressure of sequence valve is regulated when inflating, thus achieve distribution air cylinder pressure automatically, the function of sequential inflation is carried out by senior middle school's low pressure air cylinder.
Cabinet 1 is also provided with the first pressure gauge 61, second pressure gauge 62 and the 3rd pressure gauge 63.First pressure gauge 61, second pressure gauge 62 and the 3rd pressure 63 are shown to be connected the first gas tube 31, second gas tube 32 and the 3rd gas tube 33 with the 3rd arm 73, for monitoring the inflation pressure of three gas tubes respectively respectively by the first arm 71, second arm 72.
First gas tube 31, second gas tube 32 and the 3rd gas tube 33 are provided with one-way valve 10, and air-flow one-way flow when ensureing to inflate to air cylinder, to prevent gas backstreaming.
Cabinet 1 is also provided with fixed support 11, and suction tude 2, first gas tube 31, second gas tube 32 and the 3rd gas tube 33 are fixed on cabinet 1 by fixed support 11.
This sequence control cabinet regulates by the preferential aerating of high pressure group (i.e. the 3rd gas tube 33), middle pressure group sequence valve is set to 18MPa, low pressure group sequence valve is set to 20MPa pressure.When starting to inflate, on operation cabinet 1, switch valve control knob c, h, m and l are to open so switch valve 4 on each pipeline, and air-flow is entered from the suction port 8 of suction tude 2 and directly automatically preferentially inflated bomb group by the air outlet 9 of the 3rd gas tube 33.When bomb group pressure reaches 18MPa, during the pressure namely arranged more than the second sequence valve 52, the second sequence valve 52 is opened, and just fills middle pressure bottle group by the air outlet 9 of the second gas tube 32.When high, middle bottle group all reach 20MPa, during the pressure namely arranged more than the first sequence valve 51, the first sequence valve 51 is opened, and just fills low pressure bottle group by the air outlet 9 of the first gas tube 31.During as above inflation pressure value will be changed, the locking nut of sequence valve can being unclamped gently, for increasing force value during inside precession screw rod, outwards screwing out screw rod for reducing force value, regulate the complete locking nut should locking sequence valve, to ensure pressure stability and production safety.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
