Abstract
The invention relates to a two-stage controlled Venturi inlet gas mixer. The mixer can ensure that the concentration of mixed gas of different fuel gases, such as LPG, CNG, and pipeline gas, is changed with the reasonable required variation of engine variable working conditions through gas inlet negative pressure and engine rotating speed two-stage control. By adopting the mixer, the contradiction between the dynamic property and the economy of engine speed adjustment is solved, and the contradiction between the dynamic property and the economy of engine rapid speed regulation response and high-low rotating speed is solved. The mixer can meet the use requirement for rapid speed regulation response of different gas sources, such as LPG, CNG, and pipeline gas, through a two-stage controlled Venturi gas inlet device.
Description
Technical field
The present invention relates to a kind of venturi air inlet mixer of two-step evolution.
Background technique
Existing venturi type mixer, the ratio of air jet and combustion gas metering-orifice remains constant, because its difference such as composition, calorific value of combustion gas of different geographical is comparatively large, the mixture strength of existing venturi type mixer cannot change with reasonable need change, and speed of response can not conservative control in Up and down speeding for motor, power character and Economy particularly thorny, cause lifting speed operating mode incomplete combustion, less economical, discharge bad, even difficulty in starting, unstable idle.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art, a kind of venturi air inlet system of two-step evolution is provided.
A venturi air inlet system for Two-stage control, comprises gas-entered passageway and mixing chamber, and described gas-entered passageway comprises gas inlet, and suction port place is provided with mitre velve, and the push rod of mitre velve is provided with adjustment spring, and mixing chamber rear end is provided with air supply opening; Also comprise the gas compensation passage being communicated with gas-entered passageway and mixing chamber, described gas compensation passage is equipped with adjustment air throttle, regulate air throttle to be connected with rotation flyball formula speed regulator by coupling shaft.
Preferably, by the rotation flyball formula speed regulator be connected with engine interior, the centrifugal force that rotation speed change produces is produced relative displacement by coupling shaft.
Preferably, described gas-entered passageway and mitre velve form annular channel jointly.
Preferably, described air supply opening is detachable gas inlet interface.
Preferably, described spray orifice is arranged ringwise.
Preferably, the position realizing adjusting screw rod by locking limit stoper is fixed or can only towards the movement in a direction.
Patent of the present invention is a kind of venturi type mixer by air-intake negative-pressure and engine speed two-step evolution, and mixer is by the change of gas inlet mouth pressure, and the opening degree one-level realizing mitre velve controls; The rotation flyball formula speed regulator of mixer by being connected with engine interior, the centrifugal force that rotation speed change produces is produced relative displacement by coupling shaft, and then realize the control of exchanging joint joint air valve, and then realize compensation channel changes of section, and then realize Two-stage control compensation air inlet; And then realize the ratio change of air jet and combustion gas metering-orifice, realize mixture strength and change with the reasonable need change of the various operating mode of motor.
The present invention's beneficial effect is compared with prior art: mixer is by air-intake negative-pressure and engine speed two-step evolution, and the mixture strength that can meet the different combustion gas such as LPG, CNG, piped gas changes with the reasonable need change of motor variable working condition.Solve the power character of motor lifting speed and the contradiction of Economy.Solve the quick speed governing response of motor and the power character of high and low rotating speed and the contradiction of Economy.By the venturi air inlet system of two-step evolution, the quick speed governing response usage requirement of the different sources of the gas such as LPG, CNG, piped gas can be met.

Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is further described, but the present invention is not limited to these embodiments.
Venturi air inlet mixer of the present invention, with reference to shown in Fig. 1, pipe type combustion gas enters gas-entered passageway 8 through gas inlet 9, gas-entered passageway 8 tail end is cone structure, jointly annular channel is formed with mitre velve 6, mitre velve 6, by regulating the pretightening force adjustment of adjustment spring 7, forms Venturi tube structure jointly by mitre velve 6 and gas-entered passageway 8, realizes one-level and controls; Compensation channel 4 is communicated with gas-entered passageway and mixing chamber.Rotate flyball formula speed regulator 1 regulates air throttle 3 aperture by coupling shaft 2, realize combustion gas and enter mixing chamber from compensation channel 4.(can at mixer 8 housing place circumferentially 4/6 air inflow openings) realizes meeting the mixer working concentration requirements of different source of the gas under lifting speed operating mode such as LPG, CNG, piped gas.The mixed gas formed enters dissimilar motor through detachable gas inlet interface 5.
Wherein by adjustment taper adjusting screw rod 6 and adjustment spring 7, and then form corresponding Venturi tube structure according to different internal pressures, and then realize mixture strength change requirement.
The position that wherein can realize adjusting screw rod 6 by locking limit stoper is fixed or can only towards the movement in a direction, and then it is consistent with air concentration ratio to realize mixed gas, and then realizes the invariablenes turning speed of motor.
Venturi air inlet mixer of the present invention, the ratio change of the air jet realized and combustion gas metering-orifice, can realize mixture strength and change with the reasonable need change of the various operating mode of motor.
It should be noted that above-mentioned specific embodiment is exemplary, under above-mentioned instruction of the present invention, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion drops in scope.
