Abstract
A low-flow natural gas filling system comprises a liquid storage tank. A gas balance pipe is arranged above the liquid storage tank, a gas balance valve is arranged on the gas balance pipe, the other end of the gas balance pipe is connected with the upper portion of a gas channel, a liquid outlet pipe is arranged below the liquid storage tank, a liquid outlet valve is arranged on the liquid outlet pipe, the other end of the liquid outlet pipe is connected with the top of a liquid level control valve, a gas outlet pipe is arranged above the liquid level control valve and connected with the gas balance pipe, a filling pipe is arranged below the liquid level control valve, a filling control valve is arranged on the filling pipe, a filling port is arranged in the middle of the gas channel, and the filling pipe is connected with the filling port. The internal pressure of the whole system is constantly stable, negative pressure generated by gas flow generates power to extract liquid, the system does not need to be electrified, safety in the gas transportation process is improved, explosion protection for electrical appliances is omitted, and cost is further reduced.
Description
Technical field
The utility model relates to rock gas filling field and especially relates to small flow rock gas loading system.
Background technique
Rock gas need add smelly or the filling Active agent before flowing to client's use, was filled with pump injection type at present, two kinds of instillation formulas, and these two kinds of dosing methods, all must there be power supply at the scene, in inflammable, explosive place, has power supply that potential danger is just arranged; Use power supply, just must carry out explosion-proof protection to electrical equipment, so the on-the-spot cost of installing also will increase flameproof apparatus, cost of equipment is corresponding just higher.
Summary of the invention
The utility model technical problem to be solved provides a kind of small flow rock gas loading system.
The utility model solves the technological scheme that its technical problem adopted: a kind of small flow rock gas loading system, comprise liquid container, and said liquid container top is provided with gas equalizing line; Said gas equalizing line is provided with the gas equilibrium valve, and the said gas equalizing line the other end links to each other with gas channel top, and said liquid container below is provided with drain pipe; Said drain pipe is provided with liquid valve; The said drain pipe the other end links to each other with the fluid level control valve top, and said fluid level control valve top is provided with steam outlet pipe, and said steam outlet pipe is connected with gas equalizing line; Said fluid level control valve below is provided with filler pipe; Said filler pipe is provided with the filling control valve, and said gas channel middle part is provided with filler, and said filler pipe is connected with filler.
After adopting said structure, be characterized in: after rock gas got into gas channel, the gas flow that utilization itself has produced negative pressure and forms a negative pressuren zone at filler; Thereby required filling liquid is extracted out from liquid container, adjustment filling control valve, the amount that makes required servicing fluids changes according to the size of gas stream momentum; Through the adjustment fluid level control valve servicing fluids is guaranteed on a liquid level; Be connected with gas equalizing line between gas channel and the liquid container, fluid level control valve is provided with steam outlet pipe and is connected with gas equalizing line, makes and all has a certain amount of gas in liquid container and the fluid level control valve; Thereby guaranteed that the pressure in liquid container and the fluid level control valve is stable; And can control the pressure size in liquid container and the fluid level control valve through the adjustments of gas equilibrium valve, entire equipment need not power-on servicing, makes gas transmission process safe property be improved; Saved explosion-proof protection, cost is further descended electrical equipment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Among the figure: 1. liquid container, 2. gas equalizing line, 3. gas equilibrium valve, 4. gas channel, 5. drain pipe, 6. liquid valve, 7. fluid level control valve, 8. steam outlet pipe, 9. filler pipe, 10. filling control valve, 11. fillers.
Embodiment
A kind of small flow rock gas loading system shown in Figure 1 comprises liquid container 1, and said liquid container 1 top is provided with gas equalizing line 2; Said gas equalizing line 2 is provided with gas equilibrium valve 3, and said gas equalizing line 2 the other ends link to each other with gas channel 4 tops, and said liquid container 1 below is provided with drain pipe 5; Said drain pipe 5 is provided with liquid valve 6; Said drain pipe 5 the other ends link to each other with fluid level control valve 7 tops, and said fluid level control valve 7 tops are provided with steam outlet pipe 8, and said steam outlet pipe 8 is connected with gas equalizing line 2; Said fluid level control valve 7 belows are provided with filler pipe 9; Said filler pipe 9 is provided with filling control valve 10, and said gas channel 4 middle parts are provided with filler 11, and said filler pipe 9 is connected with filler 11
After adopting said structure, be characterized in: when the user needs to use gas, open gas equilibrium valve 3; Because liquid container 1 is connected through gas equalizing line 2 with gas channel 4, fluid level control valve 7 is connected through steam outlet pipe 8 with gas equalizing line 3, makes liquid container 1 and gas channel 4 and fluid level control valve 7 form gas UNICOM; Thereby make liquid container 1 and fluid level control valve 7 internal pressure stabilises, open liquid valve 6 then, make liquid container 1 through drain pipe 5 liquid of in fluid level control valve 7, annotating; Adjustment fluid level control valve 7 guarantees on a liquid level fluid level control valve 7 internal liquids, adjustment filling control valve 10; Make required filling liquid change adding amount, in gas channel 4, import rock gas then, because gas flow makes filler 11 places form negative pressuren zone according to rock gas output size; Thereby the liquid in the fluid level control valve 7 is annotated in gas channel through filler pipe 9 entering fillers 11, because whole system internal pressure all-the-time stable, the negative pressure of utilizing gas flow to produce produces power extraction liquid; The system that makes need not power-on servicing; Improved gas transmission process safe property, saved explosion-proof protection, cost is further descended electrical equipment.
