Description
Technical field
The utility model relates to a kind of built up thin wall nozzle for gas kitchen ranges.
Background technology
Nozzle is one of gas kitchen ranges strength member, one end adopt be threaded, by conduit or be directly connected with range valve, the other end stretches into injector, Main Function comprises control gas kitchen ranges load, and together with the parts such as injector, fire cover, form combustion gas ejection system.
The existing nozzle of gas kitchen ranges, the general regular hexagon brass shape extrusion that adopts forms, and two ends are bellmouth, and middle combustion gas ejection circular hole wall thickness and aperture are generally in close level, have time gas access aperture in the nozzle side after gas injection portals.
Under the effect of gaseous-pressure, combustion gas sprays from nozzle bore; Combustion gas is after nozzle bore injection, and the space after nozzle bore forms negative pressure, is sucked by air from nozzle lateral opening hole; Combustion gas mixes with the air of suction, finally injects gas-cooker injector from nozzle front openings, again forms negative pressure, sucks air.
Household gas utensils generally adopt atmospheric burning type mode, after combustion gas mixes with primary air, spray from furnace end of gas cooker fire hole, after igniting, chemical reaction occurs, form intermediate material, these intermediate materials mix with around auxiliary air again, generate carbon dioxide and water, release amount of heat simultaneously.For gas kitchen ranges, can the negative pressure formed around after being penetrated by combustion gas, a large amount of primary air is sucked injector, be the key factor of gas utensil performance.
From injection theory analysis, the fire hole gross area and nozzle bore area ratio, have material impact to combustion gas injection air, this ratio is larger, then the air of injection is more.
For plain nozzle, after nozzle bore is left in combustion gas, fuel gas flow spreads immediately at a certain angle, the negative pressure formed and the pressure differential of air access holes little, cause the suction velocity of air and soakage little, when air with when combustion gas mixing is insufficient or ratio is not enough, the efficiency of combustion of reduction combustion gas.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of built up thin wall nozzle for gas kitchen ranges.
The utility model solves the technical scheme that its technical problem adopts:
A kind of built up thin wall nozzle for gas kitchen ranges, comprise nozzle body, described nozzle body includes a small nozzle, the air duct being provided with blast tube, mixed gas passage in described nozzle body and being arranged on mixed gas passage sidewall, described small nozzle is a tubular structure and is arranged in nozzle body, be provided with a thin-walled in this small nozzle, described thin-walled offer a gas injection and portal, described gas injection portals and is communicated with blast tube and mixed gas passage.
Described gas injection portal place wall thickness be less than 0.3 with the ratio in aperture.
Described small nozzle is arranged in blast tube, described small nozzle one end open towards blast tube, described thin-walled is arranged on the other end in small nozzle.
Described small nozzle is arranged in blast tube by threaded engagement.
Also fluid sealant is provided with between described small nozzle and blast tube.
Described small nozzle openings end offers breach.
The beneficial effects of the utility model are: a kind of built up thin wall nozzle for gas kitchen ranges, comprise nozzle body, the mode such as to be threaded connection in described nozzle body is provided with a small nozzle, a thin-walled is provided with in described small nozzle, described thin-walled offers a gas injection to portal, when gas injection portal wall thickness be set to be less than 0.3 with the ratio in aperture time, then produce thin-wall effect, combustion gas is left after gas injection portals, first be shrunk to and portal more small bore than gas injection, and then there is the diffusion of certain angle, its effect is equivalent to the fuel gas flow of more hand line nozzle ejection, thus compared with plain nozzle, when other conditions are constant, thin walled nozzle possesses stronger injection ability of air, and small nozzle of the present utility model and nozzle body are fabricated structure, make nozzle, thin-walled, the processing that gas injection portals is more simple and easy convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model;
Fig. 2 is the generalized section of small nozzle of the present utility model;
Fig. 3 is the side schematic view of small nozzle of the present utility model.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of the utility model specific embodiment, as shown in the figure, a kind of built up thin wall nozzle for gas kitchen ranges, comprise nozzle body 1, described nozzle body 1 includes a small nozzle 6, blast tube 3 is provided with in described nozzle body 1, mixed gas passage 4 and the air duct 5 be arranged on mixed gas passage 4 sidewall, described small nozzle 6 is a tubular structure and is arranged in nozzle body 1, a thin-walled 61 is provided with in this small nozzle 6, described thin-walled 61 offers a gas injection and portals 62, described thin-walled 61 is between blast tube 3 and mixed gas passage 4, described gas injection portals 62 connection blast tubes 3 and mixed gas passage 4, when gas injection portal the wall thickness at 62 places be set to be less than 0.3 with the ratio in aperture time, then produce thin-wall effect, combustion gas is left gas injection and is portalled after 62, first be shrunk to and portal 62 more small bores than gas injection, and then there is the diffusion of certain angle, its effect is equivalent to the fuel gas flow of more hand line nozzle ejection, thus compared with plain nozzle, when other conditions are constant, thin walled nozzle possesses stronger injection ability of air, and small nozzle 6 of the present utility model is fabricated structure with nozzle body 1, make nozzle, thin-walled, the processing that gas injection portals is more simple and easy convenient.
As preferably, described small nozzle 6 is arranged in blast tube 3 by threaded engagement fluid sealant, and by sealant sealing, improves sealing property; As preferably, in the present embodiment, described small nozzle 6 one end open towards blast tube 3, described thin-walled 61 is arranged on the other end in small nozzle 6, between blast tube 3 and mixed gas passage 4.
