Abstract
The utility model provides a gas cutoff and flow valve of car heater, comprising a main body, a cutoff magnetic valve and a flow regulating magnetic valve. The main body is provided with a gas inlet, a gas inlet valve base, a gas on-off jet, a gas flow jet valve base and a gas outlet. The gas inlet is communicated with the gas inlet valve base through a gas jet, the gas inlet valve base is communicated with the gas flow jet valve base through the gas on-off jet, and the gas flow jet valve base is communicated with the gas outlet via a gas compensating jet and a gas main jet. The gas main jet, the gas on-off jet and the gas outlet are on normally open states. The gas inlet valve base is provided with the cutoff magnetic valve, and the gas flow jet valve base is provided with the flow regulating magnetic valve. The flow regulating magnetic valve and the cutoff magnetic valve are arranged on the same main body, and deliver gas to the gas outlet at close range, thus the gas cutoff and flux valve of car heater is characterized by small size and compact structure.
Description
Technical field
The utility model relates to a kind of combustion gas that is used for automobile-used heater and ends and flow valve, belongs to automobile-used heater control valve technical field.
Background technology
Serious day by day along with the in short supply day by day and atmosphere pollution of fuel oil, many automobiles are used economy and the better gaseous fuel of discharge performance instead.It is also imperative that the fuel oil for vehicles heater is used gaseous fuel instead as the independent heat supply device of usefulness such as automobile warming, defrost and cold start-up, but automobile-used heater use gaseous fuel need a kind of can be to the valve of combustion gas keying and Flow-rate adjustment, present gas control valve door all is not suitable for automobile-used heater on volume still is function.
Summary of the invention
The utility model provides a kind of volume little at having the needs that automobile-used heater uses gaseous fuel now, and compact conformation is applicable to that the automobile-used heater of automobile-used heater ends and flow valve with combustion gas.
Automobile-used heater of the present utility model with combustion gas by with flow valve by the following technical solutions:
By comprising body, cut-off electromagnetic valve and Flow-rate adjustment magnetic valve with flow valve, body is provided with fuel gas inlet, combustion gas air admission hole valve seat, combustion gas keying hole, gas flow ports valve seat and gas outlet to this automobile-used heater with combustion gas; Be provided with fuel gas hole in the combustion gas air admission hole valve seat, be provided with combustion gas compensating jet and combustion gas main jet in the gas flow ports valve seat; Fuel gas inlet communicates with combustion gas air admission hole valve seat by fuel gas hole, combustion gas air admission hole valve seat opens and closes the hole by combustion gas and communicates with gas flow ports valve seat, gas flow ports valve seat communicates with gas outlet by combustion gas compensating jet and combustion gas main jet, and combustion gas main jet and combustion gas open and close the hole and gas outlet is in normal open state; On the combustion gas air admission hole valve seat cut-off electromagnetic valve is installed, on the gas flow ports valve seat Flow-rate adjustment magnetic valve is installed.
The utility model designs Flow-rate adjustment magnetic valve and cut-off electromagnetic valve on same body, and low coverage is liftoff makes combustion gas go to gas outlet through cut-off electromagnetic valve and Flow-rate adjustment magnetic valve, have concurrently and end and flow control function, overall structure is simplified greatly, it is little to have volume, the characteristics of compact conformation are applicable to automobile-used heater.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, fuel gas inlet, 2, install and fix the hole, 3, gas flow ports valve seat, 4, the Flow-rate adjustment magnetic valve, 5, combustion gas compensating jet, 6, the combustion gas main jet, 7, gas outlet, 8, body, 9, combustion gas opens and closes the hole, and 10, cut-off electromagnetic valve, 11, combustion gas air admission hole valve seat, 12, fuel gas hole.
The specific embodiment
As shown in drawings, the utility model mainly comprises body 8, cut-off electromagnetic valve 10 and Flow-rate adjustment magnetic valve 4.Body 8 adopts powder art metallurgy or die casting monolithic molding, and body 8 is provided with fuel gas inlet 1, combustion gas air admission hole valve seat 11, gas flow ports valve seat 3 and gas outlet 7.Also be provided with two on the body 1 and install and fix hole 2.Be provided with fuel gas hole 12 in the combustion gas air admission hole valve seat 11.Be provided with combustion gas compensating jet 5 and combustion gas main jet 6 in the gas flow ports valve seat 3.On the combustion gas air admission hole valve seat 11 cut-off electromagnetic valve 10 is installed, on the gas flow ports valve seat 3 Flow-rate adjustment magnetic valve 4 is installed.Fuel gas inlet 1 communicates with combustion gas air admission hole valve seat 11 by fuel gas hole 12, combustion gas air admission hole valve seat 11 opens and closes hole 9 by combustion gas and communicates with gas flow ports valve seat 3, metering orifice valve seat 3 communicates with gas outlet 7 by combustion gas compensating jet 5 and combustion gas main jet 6, be provided with one in the metering orifice valve seat 3 and open and close the unimpeded annular groove in hole with combustion gas, open and close hole 9 by this annular groove combustion gas main jet 6 and combustion gas and be in normal open state, the main jet 6 of combustion gas simultaneously also is in normal open state with gas outlet 7.Cut-off electromagnetic valve 10 control combustion gas open and close the keying in hole 9, and gas flow ports valve seat 3 is led in the control combustion gas.The keying of 4 control of Flow-rate adjustment magnetic valve combustion gas compensating jet 5, Flow-rate adjustment magnetic valve 4 can make automobile-used heater be in full load or sub-load duty by opening and closing combustion gas compensating jet 5.
The course of work of the present utility model is:
By the hole 2 usefulness bolts that install and fix on the body 1 the utility model is fixed on position suitable in the car, is connected with fuel gas inlet 1 through Gas Pipe, gas outlet 7 and combustion heater are connected with Gas Pipe from the combustion gas of gas supply system.During automobile-used heater starting, its controller control cut-off electromagnetic valve 10 and Flow-rate adjustment magnetic valve 4 are opened simultaneously, and combustion gas this moment opens and closes hole 9, combustion gas main jet 6 and combustion gas compensating jet 5 by fuel gas inlet 1 through fuel gas hole 12, combustion gas and gives automobile-used heater air feed through gas outlet 7.Reach the temperature of heat supply when automobile-used heater after, controller control Flow-rate adjustment magnetic valve 4 cuts out combustion gas compensating jet 5, has only this moment combustion gas main jet 6 to give the heater fed combustion gas.Because of the combustion gas total flow reduces, so heater is with the portion of hot heat supply of loading.After the temperature of heated body was reduced to design temperature, controller control Flow-rate adjustment magnetic valve 4 was opened, and combustion gas this moment compensating jet 5 is given the heater fed combustion gas in the lump with combustion gas main jet 6, and combustion heater is with the full load heat supply, and the above course of work is gone round and begun again.When automobile-used heater was shut down, its controller cut out Flow-rate adjustment magnetic valve 4 and combustion gas cut-off electromagnetic valve 10 simultaneously, cut off the source of the gas of combustion heater, and heater quits work.
