Description
Technical field
The utility model relates to a kind of diaphragm valve, is specifically related to a kind of throttle control diaphragm valve of gas engine.
Background technique
General gasoline engines is due to tail gas pollution environment, its market substitute by gas engine, current gas valve adopts dead-beat diaphragm valve, this valve due to gas be straight, therefore, although compared with petrol engine, discharge reduces to some extent, but still can pollution of atmosphere be caused, adopt throttle control diaphragm valve, it is the progress in this field, the valve of existing gas engine, general employing single-iris dead-beat, gas directly inhales people by the action of negative pressure diaphragm, the size of air inflow cannot control according to the working state of motor, the consequence brought is, during startup, because gas concentration is too high, main air door must be opened start, when ambient temperature lower than-5 degree below time, meeting difficulty in starting, little load, during semi-load, unnecessary inflammable gas cannot after-flame, directly air can be entered with exhaust, namely gas consumption is added, befouling environment again.
Summary of the invention
It is high that the purpose of this utility model is to provide a kind of combustion efficiency, the throttle control diaphragm valve of the simple a kind of gas engine of structure.
The technical solution of the utility model is: a kind of throttle control diaphragm valve of gas engine, be provided with valve body, described valve body is provided with sky gas mixing chamber, combustion gas diaphragm chamber is respectively equipped with under empty gas mixing chamber, vacuum cavitations room, described combustion gas diaphragm chamber provides corresponding combustion gas to motor for the aperture according to closure, described vacuum cavitations room is provided with diaphragm, and according to the negative pressure that the different rotating speed of motor and power stage produce, control the operation rhythm of diaphragm, to combustion gas, diaphragm chamber provides combustion gas, combustion gas diaphragm chamber is connected by central aeration pipe with vacuum cavitations room.
Described empty gas mixing chamber is by combustion gas diaphragm chamber by the main steam line under mixing chamber, provides combustion gas respectively by main jet and idle metering jet to empty gas mixing chamber.
Be provided with throttle plate pin in described valve body, described throttle plate pin is provided with air guide valve pin, and the inclination angle of 18 degree is arranged at described air guide valve pin bottom, and the sphere of activities of described guiding valve pin is 10 °-70 ° air inflows controlling motor.
Air flue is provided with in described valve body, described air flue is provided with flow control element, described air flue and engine chamber are interconnected, and described flow control element can regulate and control the ratio of liquid gas and air, and described liquid gas and the ratio of air are between 1:0.15-1:0.2.
The utility model has the advantages that: diaphragm is arranged on and separates between pressure chamber and can carry out pressure adjustment at any time, negative pressure diaphragm drives diaphragm according to motor negative pressure, and the negative pressure required for air feed diaphragm of automatic regulating valve body, air feed diaphragm carries out aperture adjustment according to the change of valve internal negative pressure and provides corresponding inflammable gas to use to motor, guarantee under the state of different rotating speeds and output power, suitable inflammable gas can be provided, throttle plate pin increases air guide valve pin, aperture according to closure changes, carry out the adjustment of gas flow, like this, when can guarantee engine running, along with the change of rotating speed and load, synchronous adjustment gas supply flow, ensure stability and the power stage of engine running, startability, for the sufficient combustion of inflammable gas provides guarantee, more be conducive to improving exhaust index.
