Abstract

When the device works, as long as a hand valve operating line 9 is pulled, a pull handle 7, a valve shaft 5 and a choke plate 6 rotate clockwise, a closing tension spring 8 is stretched at the same time, the choke plate 6 is opened, tail gas enters an evaporator body 2, otherwise, the hand valve operating line 9 is loosened, the closing tension spring 8 is contracted, the pull handle 7, the valve shaft 5 and the choke plate 6 are pulled to rotate anticlockwise so as to reduce the throughput of the tail gas until the tail gas is completely in a closed state, so that the evaporation pressure of the automobile gas storage tank is controlled, and the requirement of driving is met.

Description

Automobile liquid gas evaporating pressure regulating controller

The utility model is the evaporating pressure regulating controller of a kind of liquefied petroleum gas automobile gas holder special use, is applicable to the regulation and control of various types of liquefied petroleum gas automobile gas holder evaporating pressures.

At present many from the external relevant apparatus of introducing, mostly can only use with the liquid gas of carbon 3 as the automobile specified of main component, and be the civil liquefied gas of main component with carbon 4 to China, because its evaporativity is lower, particularly work as low temperature season, its evaporation rate is more apparent slowly, can not satisfy the needs of galloping, and the universal of liquified gas automobile is restricted.

In view of this, the purpose of this utility model provides a kind of automobile liquid gas evaporating pressure regulating controller, and it can not only use with the automobile specified liquid gas of carbon 3 as main component, and can use again with the civil liquefied gas of carbon 4 as main component.

Achieve the above object, the utility model is realized by following proposal.This automobile liquid gas evaporating pressure regulating controller, comprise liquefied petroleum gas automobile gas holder, angle valve and pressure gauge part, it is characterized in that: the waste heat that utilizes automobile self, tail gas or circulating water are made thermal source by realizing with lower device, and this device is controlled valve, closed that spring and luck door operation line form by vaporizer, air inlet.Below the liquefied petroleum gas (LPG) gas holder, install the vaporizer body of a hollow additional, and its upper surface is contacted with the lower surface of automobile liquid gas gas holder, between the suction port of this vaporizer body and the outlet pipe of vehicle exhaust, air inlet control valve is housed, with pipeline the three is communicated with, like this, the high-temperature tail gas that automobile is discharged enters vaporizer body through air inlet control valve, because the conduction of heat, liquefied petroleum gas (LPG) in the liquid gas gas holder is heated, thereby improve its evaporating pressure and accelerate evaporation,, discharge from the relief opening of the vaporizer body the other end through the tail gas of vaporizer body.In vehicle driving, according to the needs and the manometric indicated pressure of liquid gas gas holder of driving,, adjust the aperture of air inlet control valve at any time by luck door operation line, with the evaporating pressure and the evaporation rate of control liquefied petroleum gas (LPG), guarantee the needs of driving.

Owing to adopt such scheme, the utlity model has following advantage:

1. simple in structure, easy to operate.

2. make thermal source with the tail gas or the circulating water of vehicle self, its waste heat is fully utilized.

3. according to different arbitrarily the adjusting of region with the temperature difference in season, vaporizer air inlet control valve can be by full cut-off to standard-sized sheet, and the source of the gas of liquefied petroleum gas automobile can get everywhere like this, thereby has created condition for popularizing liquefied petroleum gas automobile at the town and country wide geographic area.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1. be general illustration of the present utility model.

Fig. 2. be the vaporizer schematic top plan view.

Fig. 3. be vaporizer side-looking schematic representation.

Fig. 4. be air inlet control valve schematic top plan view.

Fig. 5. be air inlet control valve schematic side view.

In the accompanying drawing: 1. suction port 2. vaporizer body 3. relief openings 4. valve main bodys 5. curtain shafts

6. anti-aeration plate 7. pull handles 8. are closed extension spring 9. luck door operation lines 10. twisted points 11. fulcrums.

Fig. 2, Fig. 3 provide the concrete structure of vaporizer, and vaporizer body 2 is casings of hollow, have the outlet side of suction port 1 and air inlet control valve main body 4 to join on it, and its other end has relief opening 3 to communicate with atmosphere.

Fig. 4, Fig. 5 provide the concrete structure of the air inlet control valve of vaporizer, the outlet side of its valve main body 4 links to each other with the suction port of vaporizer 1, wherein there is anti-aeration plate 6 to be fixed on the curtain shaft 5, in the upper end of curtain shaft 5 pull handle 7 is arranged, in the outer end of pull handle 7 twisted point 10 is arranged, the inlet end of valve main body 4 is communicated with exhaust pipe.

Provide general structure of the present utility model among Fig. 1, behind car engine, spur an end and be loaded on the luck door operation line 9 that the operator cabin the other end is connected with twisted point 10, affect twisted point 10, make pull handle 7, curtain shaft 5 and anti-aeration plate 6 clockwise directions rotate, making an end be connected the extension spring 8 of closing that the other end is connected with twisted point 10 with fulcrum 11 simultaneously is elongated, and often anti-aeration plate 6 in the closed position is opened, part tail gas in the vehicle exhaust outlet pipe, enter valve main body 4 through connecting pipeline, and by cracking between anti-aeration plate 6 and the valve main body 4, enter the cavity of vaporizer body 2 from valve main body 4 the other ends, because the conduction of heat, liquefied petroleum gas (LPG) in the liquid gas gas holder is heated, and accelerate to evaporate, the aperture of anti-aeration plate 6 is big more, then jar interior steam output of liquefied petroleum gas (LPG) in the unit time is also big more, otherwise when loosening luck door operation line 9, the extension spring 8 of closing that then has been elongated is shunk, and affect twisted point 10, make pull handle 7, curtain shaft 5 and anti-aeration plate 6 rotate to counterclockwise direction, thereby the aperture of anti-aeration plate 6 reduces, to reduce the throughput of high-temperature tail gas, until being in closed condition fully, stop the liquefied petroleum gas (LPG) heating in jar.So just can be according to the needs of driving, regulation and control at any time enter the tail gas amount in the vaporizer body 2, reach the evaporating pressure of control liquid gas gas holder, to guarantee the needs of normal driving.
