Abstract
The utility model provides a kind of LNG mounted gas cylinder anti-overfilling control gear, in LNG gas bottle outside lining, inner bag is housed, liquid inlet pipe runs through LNG gas bottle outside lining and enters inner bag, and the liquid inlet pipe place in inner bag is provided with horizontal fixing rod, and laterally on fixing rod, corresponding feed liquor mouth of pipe place is movably equipped with valve block; Laterally the other end of fixing rod is vertically provided with the axis of guide, and in the fixing inner bag of the axis of guide, on the axis of guide, cover has annular float, between annular float and valve block, connects by crankshaft-link rod; Be provided with upper and lower spacing plate at the upper/lower terminal of the axis of guide.The utility model utilize annular float by liquid level moving up and down on guide rod, drive simultaneously crankshaft-link rod make valve block can set scope in liquid inlet pipe is closed and be opened, thereby realize to the anti-overfilling control of LNG mounted gas cylinder.Whether midway can strictly control liquid level, not limited by liquid feeding, effectively stop the danger that overfilling brings, mechanicalness structure, does not damage simultaneously, there is no later maintenance suffering.
Description
Technical field
The utility model relates to LNG mounted gas cylinder, specifically the anti-overfilling control gear of a kind of LNG mounted gas cylinder.
Background technique
Existing LNG mounted gas cylinder for safety, generally will leave 10% safe gasification space.The one, in the time filling LNG gas, control its safe gasification space by weight method, but this method is very inconvenient, gas station is difficult to accurate control.Another kind of solution is to install an air chamber additional at inner barrel axle center place, an aperture is arranged at air chamber bottom, and while filling, because aerating process is very fast, it is very slow that aperture enters liquid speed, in the time that air chamber enters a small amount of liquid, gas cylinder is just filled, prevents overfilling with this principle; But this anti-overfilling device is along with LNG gasification is CNG after having filled, and in bottle, pressure increases, and the liquid that enters this air chamber also can increase until be completely full of.As liquid feeding again midway, this device cannot ensure 10% safety space, and role is very micro-or work not again.
Also have a kind of device that LNG gas cylinder is accurately inflated, but this inflator uses outside LNG gas cylinder, also needs artificial calculating and control, but have no idea to control and realize for the safety setting of gas cylinder internal.
Summary of the invention
The utility model, in order to solve anti-excessive persistency and the conformity of inflation, solves the potential danger of LNG gas cylinder at all, the special anti-overfilling control gear of a kind of LNG mounted gas cylinder that proposes.
For this reason, the technical solution of the utility model is, the anti-overfilling control gear of a kind of LNG mounted gas cylinder,
Comprise LNG gas bottle outside lining and liquid inlet pipe, in LNG gas bottle outside lining, inner bag is housed, liquid inlet pipe runs through LNG gas bottle outside lining and enters inner bag, it is characterized in that: the liquid inlet pipe place in inner bag is provided with horizontal fixing rod, and laterally on fixing rod, corresponding feed liquor mouth of pipe place is movably equipped with valve block; Laterally the other end of fixing rod is vertically provided with the axis of guide, and in the fixing inner bag of the axis of guide, on the axis of guide, cover has annular float, between annular float and valve block, connects by crankshaft-link rod.
Improvement to such scheme is: be provided with upper and lower spacing plate at the upper/lower terminal of the axis of guide.
Beneficial effect:
The utility model utilize annular float by liquid level moving up and down on guide rod, drive simultaneously crankshaft-link rod make valve block can set scope in liquid inlet pipe is closed and be opened, thereby realize to the anti-overfilling control of LNG mounted gas cylinder.
The setting of upper and lower spacing plate reflects the height of liquid level, is convenient to adjust and control liquid level; Not only ensure the lower limit of lower limit, also ensured the highest setting of upper limit, anti-overfilling device after improvement can strictly be controlled liquid level, not limited by whether midway liquid feeding, effectively stopped the danger that overfilling brings, mechanicalness structure, does not damage simultaneously, there is no later maintenance suffering, the safety of this device in inner bag has played the effect ensureing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 A to movement locus enlarged diagram.
In figure, 1 is valve block, the 2nd, and crankshaft-link rod, the 3rd, annular float, the 4th, the axis of guide, the 5th, upper limit plate, the 6th, lower limiting board, the 7th, horizontal fixing rod, the 8th, the feed liquor mouth of pipe, the 9th, LNG gas bottle outside lining, the 10th, inner bag, the 11st, liquid inlet pipe.
Embodiment
The utility model as shown in Figure 1, 2.
The anti-overfilling control gear of a kind of LNG mounted gas cylinder, comprise LNG gas bottle outside lining 9 and liquid inlet pipe 11, in LNG gas bottle outside lining 9, inner bag 10 is housed, liquid inlet pipe 11 runs through LNG gas bottle outside lining 9 and enters inner bag 10, liquid inlet pipe 11 places in inner bag 10 are provided with horizontal fixing rod 7, and laterally on fixing rod 7, the corresponding feed liquor mouth of pipe 8 places are movably equipped with valve block 1; Laterally the other end of fixing rod 7 is vertically provided with the axis of guide 4,10 li of the fixing inner bags of the axis of guide 4, and on the axis of guide 4, cover has annular float 3, between annular float 3 and valve block 1, connects by crankshaft-link rod 2.
Be provided with upper and lower spacing plate 5,6 at the upper/lower terminal of the axis of guide 4.
Valve block 1 is axially connected with the feed liquor mouth of pipe 8 in use, crankshaft-link rod 2 is flexibly connected with valve block 1 and annular float 3, when liquid level is during lower than upper limit plate 6, annular float 3 is because of self gravitation whereabouts, band moving valve plate 1 rotates, and opens the feed liquor mouth of pipe 8, when annular float 3 drops to lower limiting board 6, valve block 1 rotates the point to C by B point, and the feed liquor mouth of pipe 8 is completely opened and got final product topping up.On the contrary, rise with liquid level, annular float 3 rises, and band moving valve plate 1 rotates the point to A by C point, until topping up is to specified value, now valve block 1 is by the feed liquor mouth of pipe 8 closure completely, and now liquid feeding rifle is because of the excessive automatic cutting-off liquid of resistance source.
Upper limit plate 5 on the axis of guide 4 and lower limiting board 6 reflect the height of liquid level, are convenient to adjust and control liquid level.Whether midway anti-overfilling device after improvement can strictly be controlled liquid level, not limited by liquid feeding, has effectively stopped the danger that overfilling brings, and mechanicalness structure, does not damage simultaneously, there is no later maintenance suffering.
