Abstract
The utility model discloses an LPG relief valve for a vehicle, which comprises a main body; a gas outlet of the main body is mounted with a three-way connection, and a gas outlet of the three-way connection is mounted with a set of pressure display device and the other gas outlet of the three-way connection is connected with an engine. The utility model has a simple, compact and reasonable structure, can conveniently, rapidly and effectively perform matching and adjustment with a constant pressure and a quantitative mode to the fuel gas according to the different power and the different displacement of the engine, supplies LPG fuel gas with stable pressure and good gasification to the engine, so as to improve the combustion efficiency of the engine, reduce the fuel gas consumption, and reduce the exhaust pollution.
Description
Technical field
The utility model relates to reduction valve, more particularly, relates to a kind of automotive LPG reduction valve that is used for providing to gasoline/LPG dual-fuel automobile motor pressure stability, the good LPG combustion gas of gasification.
Background technique
At present, in prior art, one two pass joint only is housed on the main body of automotive LPG (liquefied petroleum gas (LPG)) reduction valve (vaporizer) directly leads to motor.Adopt the reduction valve (vaporizer) of this kind structure can not observe pressure and stability thereof intuitively, can only by virtue of experience carry out unordered adjustment to reduction valve (vaporizer), influenced the power character and the Economy of motor with sensation to the motor air feed.
The model utility content
Technical problem to be solved in the utility model provides a kind of automotive LPG reduction valve, this structure of relief pressure valve is simple, compact, reasonable, can be easily and fast, according to the different capacity and the different displacements of motor the quantitative coupling adjustment of level pressure is carried out in combustion gas effectively, provide pressure stability, the good LPG combustion gas of gasification to motor, to improve the combustion efficiency of motor, reduce gas consumption, reduce exhaust pollution.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of automotive LPG reduction valve comprises main body; Place, air outlet at described main body is equipped with a tee union, and another air outlet that a cover pressure display unit and this tee union are installed on an air outlet of tee union is connected with motor.
Described pressure-display device is the mechanical compression display unit.
Described pressure-display device is the digital display type pressure-display device.
The utility model is owing to adopted said structure, two air outlets by tee union cooperate with pressure-display device and motor respectively, so the utility model can be by the supervisory function bit of pressure-display device, can be easily and fast, according to the different capacity of motor and different displacements the air feed of reduction valve (vaporizer) is carried out level pressure and quantitative coupling adjustment effectively, avoid causing combustion gas overrich or rare excessively because of unordered adjustment, thereby improve the combustion efficiency of motor, reduce gas consumption, further reduce exhaust pollution; The utility model is simple in structure, compact, reasonable; The utility model can be observed pressure and the stability thereof to the motor air feed very intuitively, has solved the unordered adjustment of can only be by rule of thumb reduction valve (vaporizer) being carried out with sensation, thereby has guaranteed the power character and the Economy of motor.
After the detailed description of reading mode of execution of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.
Description of drawings
Fig. 1 is embodiment's one an of the present utility model structural representation; And
Fig. 2 is embodiment's two an of the present utility model structural representation.
Among the figure: 1 is that adjusting screw, 2 is that pressure adjusting spring, 3 is that diaphragm, 4 is that valve rod, 5 is that valve, 6 is that return spring, 7 is that main body, 8 is that primary valve, 9 is that air input joint, 10 is that pressure-display device, 11 is that tee union, 12 is a loam cake.
Embodiment
With a mode of execution the utility model is described in further detail below, but should illustrates, protection domain of the present utility model is not limited only to this.
Embodiment one:
Consult Fig. 1, a kind of automotive LPG reduction valve, it comprises adjusting screw 1, pressure adjusting spring 2, diaphragm 3, valve rod 4, valve 5, return spring 6, main body 7, air input joint 9, pressure-display device 10, tee union 11, loam cake 12; Place, air outlet at main body 7 is equipped with a tee union 11, another air outlet that one cover pressure display unit 10 and this tee union 11 are installed on an air outlet of tee union 11 is connected with motor, wherein, pressure-display device 10 is the mechanical compression display unit.
The working principle of present embodiment and working procedure:
When LPG gas cylinder and present embodiment connection, pressurized gas are with pressure P
0Enter by air input joint 9 in the chamber A of main body 7.When rotation adjusting screw 1, the pressure that acts on the pressure adjusting spring 2 overcomes the active force of return spring 6 and forces diaphragm 3 descending, and promotion valve rod 4 is opened valve 5, pressurized gas enter relief chamber B by primary valve 8 from chamber A, relief chamber B pressure is increased, produce simultaneously thrust upwards on diaphragm 3, this thrust (be called not only feedback force) but also conversely valve 5 is turned down makes outlet pressure P
1Reduce.When the active force of the feedback force on acting on diaphragm 3 and two springs balanced each other, reduction valve just provided the pressure stable output of a certain setting to motor.When the output load of reduction valve changed, the transient equiliblium of its internal feedback power and acting force of the spring guaranteed that all the time reduction valve has pressure stable output.Because the power of motor car engine is different with discharge capacity, require the delivery pressure of reduction valve also just different with output flow, present embodiment adopts in the outlet port of main body 7 tee union 11 is installed, setting pressure display unit 10 on tee union 11, thereby can observe pressure and stability thereof very intuitively to the motor air feed, solve the unordered adjustment of can only be by rule of thumb reduction valve (vaporizer) being carried out with sensation, thereby guaranteed the power character and the Economy of motor.
Embodiment two:
Present embodiment and embodiment's one difference is: in the present embodiment, pressure-display device 10 is the digital display type pressure-display device, sees Fig. 2.
Though described mode of execution of the present utility model in conjunction with the accompanying drawings; but those skilled in the art can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present utility model, all should be within protection domain of the present utility model.
