Description
Technical field
The present invention relates to gas injection rails, in particular to gas flow to adjust valve.
Background technique
With the rapid growth of car ownership, environmental pollution and petroleum resources shortage problem are on the rise.For this purpose, the world
Actively develop the R&D work of new-energy automobile in various countries.Wherein, natural gas vehicle is low with its discharge, inhibits greenhouse effects and gets rid of
Three big characteristics are relied on to petroleum, is just worldwide popularized and is promoted.In China, many city bus and taxi
There is great amount of fuel oil vehicle to use or used instead compressed natural gas (CNG) or liquefied petroleum gas (LPG) instead.With China
Increasing rapidly for gas combustion automobile ownership, it is also imperative to develop matched combustion heater.
In the electronic controlled gas injection system of gaseous propellant engine, the device of most critical first is that gas ejector, its property
Energy superiority and inferiority directly affects the jet quality of fuel.However, structure is complicated for spray rail spool in the prior art, the stabilization of nozzle flow
Property it is insufficient, the adjusting of gas flow is more lagged in adjustment process, for example when increasing or reducing flow output by spraying
The gas flow variation that mouth ejects is slower.
Summary of the invention
The purpose of the present invention is to provide gas flows to adjust valve, increases the rate of change of fuel gas supply amount in spray rail, into
And the purpose of gas flow flexible modulation.
The purpose of the invention is achieved by the following technical solution:
Gas flow adjust valve, the solenoid valve seat including being provided with electromagnetic coil on inner wall, in the solenoid valve seat by
It is disposed with moving valve, shell from inside to outside, the shell upper end extends outwardly, and is provided in inside in the shell lower end
Empty connector, there are gaps between connector upper end and moving valve lower end, are threaded with valve nozzle in the elongated end of shell, institute
The air flue for being provided with inside moving valve and being connected in the middle part of connector is stated, spring is arranged in air flue, and on the moving valve side wall
It opens there are two the through-hole that be connected to air flue, moving valve upper end and valve nozzle inside are connected to, and are provided on the circumference on valve nozzle top more
A fumarole further includes the straight tube that axis is overlapped with the axis of valve nozzle, and the straight tube is made of tube body and connecting tube, described
Bottom of the pipe is connect with the open end at the top of moving valve, and upper end of connecting tube runs through the top of valve nozzle, and connecting tube lower end is through pipe
It the end face of body and extends downwardly, in connecting tube lower end, outer rim is provided with to protrude outward forms seal chamber between inboard wall of tube body,
And the oil liquid of 1/2 volume is marked in seal chamber；When adjusting gas flow exports, by the changes of magnetic field of electromagnetic coil, make
Valve body moves in a straight line in the vertical direction, to adjust the contact area size of through-hole and inner walls.
In the prior art, the supply of combustion gas is directly transmitted often through fuel gas pipeline, up to not in terms of the adjustment of air demand
To the requirement of precise fine-adjustment, so that gas supply is unable to satisfy actual demand；When the invention works, for supplying normal discharge,
The corresponding end surface of moving valve and connector contacts with each other, and through-hole is blocked by inner walls completely, and combustion gas passes through in connector
Portion enters in air flue, is flowed into straight tube by the open end at the top of air flue, finally flows out by straight tube upper end；And work as
When needing to increase gas supply amount, the magnetic field around moving valve is changed by electromagnetic coil in solenoid valve seat, so that moving valve
Be detached between connector, i.e., moving valve moves up, at this point, the through-hole being connected to air flue gradually with connect inside valve nozzle
It is logical, i.e., it can be entered in valve nozzle by the open end at the top of through-hole and moving valve by the combustion gas exported inside connector, only need to increase
Combustion gas input quantity at big connector then can increase the final combustion gas output quantity of valve nozzle, compared with prior art, equally increase
Under the premise of combustion gas input quantity, the output quantity of single gas distribution channel and then realizes spray well below the output quantity of double gas distribution channels
The rate of change of fuel gas supply amount in rail, achievees the purpose that gas flow flexible modulation.Also, on the excircle at the top of valve nozzle
Multiple fumaroles are set, is suitable for combustion gas when gas quantity in air flue increases or reduces and stablizes output, wherein valve nozzle and shell
Elongated end be threadedly coupled, quick-replaceable can be carried out to it when valve nozzle is damaged, and then avoid to spool and solenoid valve seat etc.
The integral replacing of component reduces use cost.
Also, the axis of straight tube is overlapped with the axis of valve nozzle, while improving the stability sprayed outside combustion gas, guarantees valve nozzle
The flow ejection efficiency at place；And straight tube is made of tube body and connecting tube, connecting tube is fixed when gas supply, and tube body is in servo-actuated valve body one
When playing movement, the coupling part between tube body and connecting tube is fully sealed using the oil liquid in seal chamber, prevents gas to reach
The purpose leaked.
Cushion is installed in the gap.To reduce the impact between moving valve and connector end, in gap location
Cushion is installed, on the one hand can guarantee that moving valve keeps moving back and forth on stable vertical direction, on the other hand can also will subtract
The abrasion of small moving valve end face, extends the service life of moving valve.
O-ring is installed in the junction of the valve nozzle outer wall and shell elongated end inner wall.Since valve nozzle and shell extend
End is is threadedly coupled, and to further strengthen the connection sealing between valve nozzle and shell, it is close that setting O-ring is not only able to achieve enhancing
The purpose of sealing property, moreover it is possible to buffer combustion gas when spraying to the impact dynamics between shell and valve nozzle junction, to guarantee to fill
Set whole stability.
Compared with prior art, the present invention having the following advantages and benefits:
1, multiple fumaroles are arranged in the present invention on the excircle at the top of valve nozzle, be suitable in air flue gas quantity increase or
Output is stablized in combustion gas when reduction, and wherein valve nozzle is threadedly coupled with the elongated end of shell, can be carried out fastly when valve nozzle is damaged to it
Speed replacement, and then the integral replacing to components such as spool and solenoid valve seats is avoided, reduce use cost；
2, the present invention installs cushion in gap location, on the one hand to reduce the impact between moving valve and connector end
It can guarantee that moving valve keeps moving back and forth on stable vertical direction, on the other hand can also will reduce the mill of moving valve end face
Damage, extends the service life of moving valve；
3, the present invention setting O-ring be not only able to achieve enhancing sealing performance purpose, moreover it is possible to buffer combustion gas spray when pair
Impact dynamics between shell and valve nozzle junction, to guarantee the stability of device entirety.
