Description
Technical field
The utility model belongs to a kind of motor car engine parts, particularly a kind of fuel for motor vehicle conversion equipment.
Background technique
Raising along with high speed development of national economy and living standards of the people, the improvement of city environmental pollution has become the major issue that people pay close attention to, especially the excessive emissions of vehicle exhaust has become the keypoint treatment content of municipal pollution, and adopting simply, effectively and efficiently in the process of administering, one of method just is to use clean automobile fuel rock gas or liquefied petroleum gas (LPG).But after being to use clean automobile fuel the high-pressure gas in the air cylinder must be carried out reduction vaporization through conversion equipment, just can offer the firing chamber work of motor.For adapting to the needs of existing market, develop relevant product technology successively, a kind of electric heating type automobile LP gas fuel conversion equipment is for example arranged, underpressure chamber and vaporization chamber are set in housing, air inlet control mouth and outlet nozzle are set on housing, and pass through the rubber cushion sealing of two fork one ends respectively.There is following deficiency in this kind structure, and air inlet control mouth and outlet nozzle then need whole replacing housing in use as being damaged, and maintenance cost strengthens, and causes bigger waste.In assembling to the matching requirements of fork than higher, otherwise poorly sealed, and the end that fork is assembled with seal rubber pad is planar to air inlet control mouth, in the use as car body produce and jolt, the microdisplacement of fork can make the seal rubber pad place produce and leak gas.These all can influence its usability.
The model utility content
The purpose of this utility model provides a kind of fuel for motor vehicle conversion equipment, and reasonable in design is assembled easy to usely, improves usability, significantly reduces maintenance cost.
The purpose of this utility model is achieved by the following technical solution: underpressure chamber and vaporization chamber are set in housing, the air inlet control mouth that leads to the underpressure chamber is set on housing, the little flexible sheet of assembling in the underpressure chamber, little flexible sheet one side is provided with spring and adjusts screw, and opposite side is assembled with small lever; The ventilation control mouth that is led to vaporization chamber by the underpressure chamber is set on housing, the big flexible sheet of assembling in vaporization chamber, big flexible sheet one side is assembled with big lever, it is characterized in that: small lever one end connects little flexible sheet, and the other end is positioned at air inlet control mouth place recessed holder is set, and connects the air inlet nozzle lining at air inlet control mouth internal thread, assemble control valve on the air inlet control mouth, the top of control valve is for inserting the guide rod of air inlet control mouth, and the bottom is the oblate spheroid shape, and the bottom of control valve installs elastic sealing gasket; Big lever one end connects big flexible sheet, and the other end is provided with spring and adjusts screw, connects ventilation mouth lining at ventilation control mouth internal thread, on the outer circumferential face of ventilation mouth lining the idling vent is set, and it is stifled that big lever is positioned at the place's assembling sealing of ventilation control mouth.
The utility model has the advantages that: reasonable in design, assemble easy to usely, improve usability, significantly reduce maintenance cost.
