The specific embodiment
Specify the utility model below in conjunction with accompanying drawing, it is as the part of this specification, through embodiment the principle of the utility model is described, other aspects of the utility model, and characteristic and advantage thereof will become very clear through this detailed description.
The cutaway view of a kind of gas regulator that Fig. 1 provides for the utility model; Fig. 2 is the vertical view of a kind of gas regulator shown in Figure 1.Shown in Fig. 1-2; A kind of gas regulator 100 that the utility model provides; This gas regulator 100 comprises a lengthwise type regulator body 101; Wherein this regulator body 101 end along its length is provided with air inlet 1, and its other end is provided with fuel gas gas outlet 3, is provided with gas inlet 2 between the two ends along its length of this regulator body; Above-mentioned regulator body 101 inside set gradually between air inlet 1 and fuel gas gas outlet 3 and are useful on the air speed-raising chamber 4 that is communicated with air guide, hybrid chamber 6 and hybrid chamber 7 for the second time for the first time; Wherein this gas inlet 1 negative pressure chamber 5 inner with being arranged on regulator body 101 are connected, this air speed-raising chamber 5 be provided with one the first time between the hybrid chamber 6 and be used to be connected negative pressure chamber 5 and lead the annulus 8 of transporting combustion gas.
Air gets into air speed-raising chamber 4 through air inlet 1 (direction of arrow A) and accelerates flowing velocity; Combustion gas is sucked by negative pressure chamber 5 through gas inlet 2 (direction of arrow B); Air meets in annulus 8 with combustion gas and mixes; Get into hybrid chamber 6 for the first time, process hybrid chamber 7 second time is accomplished evenly at pressure releasing process and is mixed again, passes through the suitable high-quality fuel gas of fuel gas gas outlet 3 (direction of arrow C) output performance unanimity air pressure at last.
A kind of gas regulator 100 that the utility model provides; Its air speed-raising chamber 4 comprises conical air speed-raising chamber 41 and cylindrical shape air speed-raising chamber 42; The outer end in wherein said conical air speed-raising chamber 41 is connected with air inlet 1; Its other end is connected with an end in cylindrical shape air speed-raising chamber 42, and the other end in this cylindrical shape air speed-raising chamber 42 is connected with annulus 8.
Be set to conical air speed-raising chamber 41 and cylindrical shape air speed-raising chamber 42 through chamber 4 that air is raised speed, make it have the Venturi tube structure, can make air in this canalis spinalis, shrink supercharging and quicken to flow, improve the flow velocity of air.
Preferably, along on regulator body 101 length directions, this taper shape air speed-raising chamber 41 is 23: 8 with the length ratio in cylindrical shape air speed-raising chamber 42.
A kind of gas regulator 100 that the utility model provides, its for the first time hybrid chamber 6 be cylindrical shape, the one of which end is connected with annulus 8, its other end with the second time hybrid chamber 7 be connected.After air and combustion gas converge through annulus 8, realize that air fuel gas tentatively mixes in the hybrid chamber 6 in this first time.
The hybrid chamber 7 second time of gas regulator 100 is conical; The one of which end is connected with hybrid chamber 6 for the first time; Its other end is connected with fuel gas gas outlet 3, wherein for the second time the radius of the end that is connected with first hybrid chamber 6 of hybrid chamber 7 less than the radius of its end that is connected with fuel gas gas outlet 3.That is, the less end of hybrid chamber 7 its radiuses second time of this taper is connected with first hybrid chamber 6, and the end that its radius is bigger is connected with fuel gas gas outlet 3, forms reverse taper.Thus; Through hybrid chamber 6 premixed combustion gas and the air first time; Pass through taper in order for the second time hybrid chamber 7 time; Decompression reduction of speed in this specially designed taper hybrid chamber 7 (reverse taper) internal channel second time is accomplished evenly mixing at pressure releasing process simultaneously, passes through the suitable high-quality fuel gas of the consistent air pressure of fuel gas gas outlet 3 output performances at last.
In order to reduce the size of this gas regulator 100, preferably, this annulus 8 is 2-3mm along the wide of said regulator body length direction.The wide 2-3mm of being set to of this annulus 8 can be made things convenient for installation realizing further reducing the adjuster size on combustion gas and the basis that air mixes.
Preferably, the center line of the center line of this air inlet 1 and gas inlet 2 is perpendicular.Be the end that air inlet 1 is arranged on gas regulator main body 101, gas inlet 2 is arranged on the gas regulator main body 101, and perpendicular with this air inlet 1, can make appearance looks elegant thus, and makes things convenient for air, combustion gas transportation.
Preferably, this gas inlet 2 is arranged on the regulator body 101 end near air inlet 1.So design can further facilitate air, combustion gas mixing transportation.
The diameter in the cylindrical shape air speed-raising chamber 42 in the above-mentioned air speed-raising chamber 4 is 13: 160 with its length ratio.
In order to control the combustion gas charge flow rate, gas inlet 2 is provided with the combustion gas metering pin valve 9 that is used to regulate gas flow.When gas flow is excessive or too small, can select to close or open this combustion gas metering pin valve 9, realize that in order to the air fuel gas flow air cooperates with the combustion gas optimised quantity.
Consider the air centralizedly supply, its flow is much larger than gas flow, and gas quantity is regulated and more need be stablized with accurate, so arrange air to keep straight on along trunk line, combustion gas gets into from the side and independent combustion gas metering pin valve 9 is regulated.The about 3.5-4kPa of combustion air pressure; Get into from air inlet 1, utilize a fine taper air speed-raising chamber 4 to improve flow velocity, make gas inlet 2 place negative pressure chamber 5 form negative pressure; Mix with high-speed air through a 2-3mm annulus 8 subsequently; Get into mixed once chamber 6 and stablize flow velocity, then get into secondary mixing relief chamber 7 and improve mixed effect, what see off at last is exactly the high-quality fuel gas that mixes.The supply of combustion gas is regulated with combustion gas metering pin valve 9 as required, and the supply size of air is the control of dress ball valve on supporting in addition pipeline.
This shows that a kind of gas regulator that the utility model provides can make that combustion gas mixing is effective; Combustion gas kind and pressure are applied widely, and easy to adjust simple in structure, hermetically-sealed construction is reliable; Taken into account light and handy and durability double requirements after the whole integrated design, be easy to the production of mold casting volume, processing cost is lower; Good looking appearance has good economic benefit.
The above preferred embodiment that is merely the utility model that discloses can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
