Abstract
The utility model relates to an automotive liquified gas evaporating pressure regulator, which comprises a preheating pipe, a pressure regulator and a distributor vacuum valve. The utility model is characterized in that an evaporating plate is arranged between an evaporator shell and the interlayer of the evaporator, and the lower end of the evaporator shell is provided with a water inlet which is communicated with the waterway hole of the evaporator. One side is provided with the air supply valve of an inlet port which is communicated with the evaporating plate, and one side of the air supply valve is provided with a pressure regulating valve seat. A valve head assembly is arranged in vertical direction. A lever and the valve head assembly are connected by a pin, and a diaphragm assembly is arranged on the lever. The periphery of a pressure adjusting spring arranged on the diaphragm assembly is provided with a pressure regulator cover, on which is provided with a pressure regulating screw plug, and the outside is provided with a voltage regulation dust cover. Because the evaporative capacity is enlarged, the normal and stable working of the engine can be ensured. The utility model has the advantages of simple manufacturing process and high air tightness.
Description
The utility model relates to engine fuel supply device, is specially adapted to the water-cooled petrol engine.
The existing patent No.: 90206291.3, it is made up of vaporization chamber, step down transformer etc., and its shortcoming is that the preheating pipe preheating area in the vaporizer is little, connects with copper pipe, sebific duct between each assembly, and complex process is to adopt mechanical linkage when controlling the gas in the mixer.
The utility model is at above-mentioned shortcoming, and it is simple to propose a kind of technology, and amounts of preheat strengthens, and adopts the liquified gas automobile evaporation pressure regulator of the automatic air feed of vacuum.
Task of the present utility model is finished like this, it comprises economizer bank, pressure governor, the distributor vacuum valve, it is characterized in that in the interlayer of evaporator shell and vaporizer evaporation plate being arranged, the evaporator shell lower end is that water intake communicates with the water channel hole of vaporizer, evaporator shell one side is a suction port, what communicate with evaporation plate is steam supply valve, steam supply valve one side is a pressuring adjusting valve base, the pressuring adjusting valve base Vertical direction is the valve head assembly, is connected with pin between lever and the valve head assembly, is connected with diaphragm unit on the lever, it on the diaphragm unit pressure adjusting spring, the pressure adjusting spring periphery is the pressure governor lid, and the pressure governor face of covering is the pressure regulation plug screw, and the pressure regulation dust cover is arranged outside it.Evaporation plate is that circle has snakelike tank.
The utlity model has following effect; Owing to strengthened steam output, can guarantee the motor normal and stable operation, and it is simple to have technology, advantage such as tightness is good.
Accompanying drawing 1 is a front section view of the present utility model;
Accompanying drawing 2 is plan views of the present utility model;
Accompanying drawing 3 is sectional views of Fig. 2 A-A direction;
Accompanying drawing 4 is worm's eye views of the present utility model.
Describe embodiment in detail in conjunction with above accompanying drawing.The pressure governor dust cover has regulator bolts 2 for 1 li, be pressure governor lid 4 below, the below is a diaphragm unit 5, valve head assembly 6, lever 7 strings connect with pin in the following square hole of diaphragm unit 5, pressure governor shell 9 usefulness pressure governor bolts 8 link together with pressure governor lid 4, the outside is that evaporator shell 13 usefulness clamping bolts 17 are fastening with vaporiser body 11, evaporation plate 12 is arranged in it, what communicate with evaporation plate is steam supply valve 20, steam supply valve 20 1 sides are pressuring adjusting valve bases 19, and there are screw plug 18 sealings the opposite side outer end, is water supply connector 14 below evaporation plate, one side is an air input joint 15, the suction tude that vacuum switch 21 connects on the motor.During work, through the water channel hole 30 of water supply connector 14, cool off and preheating by water outlet joint 25 return engines and water tank circulation by evaporator shell 13 and vaporizer 11 by the preheating water in the motor.Air input joint 15 is connected with steel cylinder, and liquid state and gaseous state gas entered in the evaporation plate 12 by air input joint 15, at this moment evaporation plate 12 has been heated, two kinds of gases that advance the people are carried out forced evaporation, become high-pressure gaseous gas, by steam supply valve and the pressuring adjusting valve base 19 that is opened, enter the cavity of pressure regulation body 10, and promotion diaphragm unit 5, compression pressure adjusting spring 3 and pressure regulation plug screw 2, suffered gas spring 3 reaction forces drive lever 7, promote valve head assembly 6 and open and close valve seat 19 repeatedly, guarantee the normal operation that has normal pressure and enough gas to supply vacuum switch 21 at any time.Air in when work pressure governor lid 4 comes its pressure of balance according to the fluctuation of diaphragm unit 5 by the vent of pressure regulation plug screw 2 and pressure governor dust cover 1.Joint on the vacuum switch 21 is according to the size of the throttle opening of Carburetor, the variation of degree of vacuum moves up and down the diaphragm in the vacuum switch 21, drive vacuum valve rod 29 and promote air feed and dial vent in the sides of a garment 28, change the gap of air feed valve head 26 and air feed valve seat 27, adjusting tolerance is connected with Carburetor by air connector 23, idling pipe joint 24 connects motor, adjusts the idling screw, makes motor proper functioning under the idling situation.In order to guarantee vaporizer, establish cock of water drain 16 use that discharges water winter at low temperatures not by bursting by freezing.
