Description
Technical field
The utility model relates to a kind of gas mixer that is used for combustion gas and air mixing, belongs to the gas engine technology.
Background technique
The gas mixer that the utility model relates to is to be used to comprise the inflammable gas of coal gas, liquefied petroleum gas (LPG), rock gas and biogas and the gas mixture of air mixing.It provides source of the gas for the gas engine firing chamber by suction tude.And, can or claim that accelerator is connected by voltage stabilizing air storage bag and air volume regulator in they the place aheads.Its function is air and inflammable gas are mixed into combustion gas and Air mixing gas in suitable ratio, then by negative pressure that said engine chamber produced and be inhaled into firing chamber internal combustion work done.
The existing gas mixer that is used for combustion gas and air mixing all is a leather cup formula or diaphragm type elasticity input gas mixer.This existing gas mixer, structure more complicated not only, maintaining is cumbersome; And long meeting distortion service time or damage; Especially the ratio of its air and combustion gas mixing is to be regulated by the air valve linkage of itself and air valve interlock.Under operating mode, its adjusting is not only cumbersome, and is subjected to the human factor influence easily, and directly has influence on the output power of motor.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, maintaining is convenient, not fragile and long service life, operation is simple and easy under the operating mode, the gas mixer that is used for combustion gas and air mixing with automatic adjusting air and combustion gas mixing ratio is to solve the existing problem and shortage of prior art.
The technological scheme that realizes the purpose of this utility model is, a kind of gas mixer that is used for combustion gas and air mixing, its improvement is: comprise the housing that is provided with the gas mixing chamber, be arranged in the I air flue and with air flue the friction tight the 1st unidirectional vent valve, be arranged in the II air flue and with air flue the friction tight the 2nd unidirectional vent valve, be arranged in the III air flue and with air flue the friction tight the 3rd unidirectional vent valve be provided with the trunnion of 1 air outlet hole at least; Put on the inwall that is held in the gas mixing chamber at the two ends of trunnion; One end of I air flue can be connected with gas inlet pipe and its other end is connected via the 1st air outlet hole and trunnion by the 1st unidirectional vent valve; One end of II air flue is connected by the 1st through hole and I air flue; And its other end is connected via the 2nd air outlet hole and gas mixing chamber by the 2nd unidirectional vent valve; One end of III air flue is connected by the 2nd through hole and II air flue, and its other end is communicated with the 2nd air outlet hole by the 3rd unidirectional vent valve via outlet passageway and the gas mixing chamber is connected.
Can understand by above given technological scheme, when by the combustion gas in the voltage stabilizing air storage bag with certain pressure, enter the I air flue by gas inlet pipe and enter trunnion via the 1st unidirectional vent valve and through the 1st air outlet hole, again via the air outlet hole that is located on the trunnion, after the air mixing that enters with gas mixing chamber by housing, enter said engine chamber burning work done, this moment, said motor was promptly with the running of platform speed.Regulate the air demand of accelerator (being air volume regulating valve) subsequently, meanwhile, under said engine chamber suction function, even if the 2nd unidirectional vent valve of II air flue is opened, combustion gas is promptly by the 1st through hole, after entering the gas mixing chamber and air mixing of housing via the 2nd unidirectional vent valve through the 2nd air outlet hole,, be inhaled into the combustion chambers burn work done of said motor together simultaneously with combustion gas that is entered by the I air flue and Air mixing gas.The running because the increase that enters the gas quantity of said engine chamber, said motor are promptly raised speed.You continue, regulate the air demand of accelerator (being air volume regulator) again, meanwhile, under the condition that the negative pressure of said engine chamber is further strengthened, the 3rd unidirectional vent valve that is located in the III air flue is opened immediately, combustion gas promptly by the 1st through hole and the 2nd through hole, through outlet passageway and the 2nd air outlet hole, enters the gas mixing chamber of housing via the 3rd unidirectional through hole valve.At this moment, because combustion gas is entered the combustion chambers burn work done that is inhaled into said motor after the gas mixing chamber of said housing and the air mixing simultaneously by I, II, III air flue.Because the gas quantity that supplies increases once again, said motor is accelerated service.By the adjusting of said accelerator tolerance, can realize the adjusting of said engine speed.Thereby realized the purpose of this utility model of automatic adjusting air and combustion gas mixing ratio.Simultaneously can understand that by its structure what the utility model had is simple in structure, not fragile, easy to maintenance, characteristics such as long service life all are fairly obvious.
Further improvement of the utility model point also is:
The 1st unidirectional vent valve, the 2nd unidirectional vent valve and the 3rd unidirectional vent valve are formed by shell, spool, spring and end cap; The included spring of the 1st unidirectional vent valve is that steel wire diameter is that φ 0.2～0.3mm, external diameter are the cylindrical spring of φ 1.5～2mm, and the 2nd unidirectional vent valve and the included spring of the 3rd unidirectional vent valve all are that steel wire diameter is that φ 0.45～0.55mm, external diameter are the cylindrical spring of φ 3.5～4mm.Structure by above given unidirectional vent valve can be understood, said unidirectional vent valve is common simple in structure, the unidirectional vent valve of service-strong that adopts, thereby further simplified overall structure of the present utility model, and because the shell of said unidirectional vent valve is cylindric, this just can realize that with said air flue the sealed type drive fit connects easily and effectively.And the specification of the included cylindric spring of the unidirectional vent valve that provides, it is the optimum specifications that the applicant sets by repetition test, it can satisfy the gas engine that is repacked into by medium and small power diesel engine fully, the requirement of opening said three kinds of different unidirectional vent valves automatically under platform speed, three kinds of different conditions of speed-raising and acceleration.
