Description

The system that transports and the air entraining substation system of compressed natural gas storage steel bottle and formation thereof
One, technical field
The utility model relates to a kind of rock gas utilization equipment, and more particularly, the compressed natural gas that relates to a kind of natural gas automobile secondary gas filling station system and formation air entraining substation system transports system and constitutes the steel cylinder that compressed natural gas transports system.
Two background techniquies
The patent No. a kind of compressed natural gas (CNG) air entraining substation proprietary system that has been 5884675 U.S. Patent Publication, this system mainly transports the operating control device formation that natural gas injection was annotated back and added to automobile to system, hydraulic station system, refueling system and control hydraulic oil by compressed natural gas (CNG).Wherein compressed natural gas transports system and is made up of many groups steel cylinder of store compressed rock gas again, the steel cylinder of each store compressed rock gas all designs one in its bottle can be along the piston of its axial-movement, the steel cylinder bottleneck disposes end plug, design has three import and export on the end plug, one for compressed natural gas import and export, one be gas inlet and outlet in the accumulator, one is the high-voltage oil liquid import and export.The steel cylinder group is transported to gas station after the female station of natural gas fills CNG, in gas station, high-voltage oil liquid promotes circulating piston motion, CNG in the steel cylinder is pressurized under the impetus of piston, and be squeezed out bottle by the outlet that is located at the steel cylinder the other end, be injected into by flexible pipe in the fuel cylinder of automobile.Every group of steel cylinder all is furnished with an accumulator, and when the CNG in the steel cylinder discharged fully, moving under the promotion of the pressed gas of piston in accumulator resetted, and makes hydraulic oil liquid discharge steel cylinder and gets back in the liquid storage fuel tank.The place of this compressed natural gas air entraining substation proprietary system deficiency is that one is because each steel cylinder all has a piston, piston and the piston cylinder that matches with it all must carry out fine finishing, so manufacture cost is very high, the shuttling movement that piston is frequent, the kinematic pair quick abrasion, working life is shorter; Its two, the oil cylinder of circulating piston is made condition restriction, discharge capacity is little, commutation is frequent, exhaust gas pressure pulse is bigger, so safety coefficient is lower.Publication number is that the patent application of CN1486409A discloses another kind of compressed natural gas (CNG) air entraining substation proprietary system, compressed natural gas storage steel bottle in this natural gas supply sub-station proprietary system is vertical steel cylinder, the steel cylinder volume is little, and only be provided with bottleneck, constitute the vertical steel cylinder One's name is legion that compressed natural gas transports system in the upper end of steel cylinder.Because the steel cylinder volume is little, and only be provided with bottleneck in the upper end of steel cylinder, therefore the compressed natural gas access way of steel cylinder is less, flow is restricted, and constitute the steel cylinder One's name is legion that compressed natural gas transports system, so operational system is coordinated complexity, operating cost height, the rate of fault height, it is applied and is very limited.
Three summary of the invention
At the deficiency that exists by the compressed natural gas storage steel bottle of prior art, the purpose one of this practical choosing provides a kind of compressed natural gas storage steel bottle of new structure, two compressed natural gass that provide the new structure that the compressed natural gas storage steel bottle by the disclosed new structure of model utility constitutes transport system, three compressed natural gass that provide by the disclosed new structure of model utility transport the natural gas automobile secondary gas filling station system that system forms, the manufacture cost that exists with the natural gas automobile secondary gas filling station system that overcomes prior art is very high, working life is short, exhaust gas pressure pulse is big, safety coefficient is low, operational system is coordinated complicated, the high deficiency of operating cost and rate of fault.
The technological scheme of compressed natural gas storage steel bottle that realizes above-mentioned model utility purpose is as follows:
