Abstract
The utility model relates to an engine, particularly a dense fog type carburetor for a jet engine. The rear of the oil outlet of the pin valve of the gasoline throttle of the carburetor is provided with a tangential gas-jetting hole which is tightly near to the oil outlet of the gasoline throttle, the opening of the tangential gas-jetting hole faces towards the direction of a combustion chamber, and an active mode tangential straight jetting gasoline throttle is formed. When the engine is started and operated, a gas pump and a fuel gas feedback tube are manually started to respectively supply compressed gas for the tangential gas-jetting hole, and fuel oil accompanied with the compressed gas is jetted to expand and atomize into the dense fog state. Because the dense fog type carburetor and the compressed gas are used, the method of active mode tangential expansion, atomization and oil supply for the overall process of the work of the jet engine is realized, and the jet engine is convenient for starting, and is stable and reliable for operation.
Description
The utility model relates to a kind of jet engine, specifically belongs to a kind of jet engine dense fog formula Carburetor.
Jet engine is applied to smoke machines, atomizing sprayer, is one of agricultural plant protection dispenser facility.Form by firing chamber, Carburetor, oil supply system, electronic ignitin system, pneumatic starting device and cooling system etc. by a kind of known jet engine.Carburetor is the critical component of jet engine, in use still needs the effective Carburetor of a kind of carburetion so far, satisfies the needs of jet engine starting and operation.
The purpose of this utility model just provides a kind of jet engine dense fog formula Carburetor.It should be able to make the fuel oil high atomisation, and favourable electrical spark point fuel vapor is effectively improved the starting performance and the working stability of jet engine.
The scheme of its solution is: at the rear of Carburetor throttle needle-valve oil outlet, be provided with near its throttle oil outlet, opening is formed active tangential straight oil spout door towards the tangential fumarole of firing chamber direction.Allow gas circuit lead to this tangential fumarole, make the pressurized gas of ejection act on the throttle oil outlet, and do tangential motion, make oil circuit produce negative pressure along the throttle oil outlet with initial velocity, make the fuel oil of ejection change into the dense fog shape, spray to engine chamber with the pressurized gas expansion fog.
Further improvement of the present invention is: pull out in jet engine the combustion gas feedback pipe of opening towards the firing chamber is set on the tracheae, and connect with conduit and one-way valve, after the starting gas circuit is in parallel, realize that tangential fumarole and combustion gas feedback pipe links.Pressurized gas during the jet engine starting is provided by the manual starting air pump; Pressurized gas after the starting feeds back pipe in jet engine work overall process by the combustion gas of pulling out in the tracheae, take high-pressure gas to supply with tangential fumarole, make expand continuously atomizing and the fresh air that sucks in of intake valve of fuel oil spray into jet engine combustion chambers burn together.
Major advantage of the present invention is: use this dense fog formula Carburetor and adopt pressurized gas, realization is to the method for the active tangential expansion atomizing fuel feeding of jet engine work overall process, the mist of oil that obtains can reach height dense fog state, help electrical spark point fuel vapor, thereby solved the difficult old problem of jet engine starting, improved the stability and the reliability of the normal operation of jet engine.
Accompanying drawing has been described one embodiment of the present of invention.
Fig. 1 bears the cold jet engine plan view of type vapour.
Fig. 2 is equipped with the cold jet engine main body of vapour and the supplying oil and gas schematic diagram of dense fog formula Carburetor.
Fig. 3 dense fog formula carburetor structure figure.
Fig. 1 has described and has born the cold jet engine of type vapour, forms by bearing part and pivotable parts.Bearing part is made up of cooling water tank (1), medicine-chest (2), fuel tank (3), manual starting air pump (4), electronic ignition device critical pieces such as (5).Pivotable parts is made up of jet engine firing chamber (6), dense fog formula Carburetor (7), spark plug (8), vapour cold shut hot jacket critical pieces such as (9).Oil pipe, tracheae, high-tension busbar with the metallic hose protection between two-part are connected.This machine can be directly used in farmland high temperature smoked kill and weed a garden; On puff prot, load onto spraying annex or smog annex, just can be used for agricultural, forestry plant protection spraying pesticide.
Fig. 2 has described cold jet engine main body of vapour and supplying oil and gas situation.Pull out at motor and opening to be set on the tracheae (10), connect, after the starting gas circuit is in parallel, lead to the tangential fumarole (18) of dense fog formula Carburetor (7) simultaneously with conduit and one-way valve (17) towards the combustion gas of firing chamber feedback pipe (11).During starting, manual priming pump (4) is beaten sufficient starting air, the throttle needle-valve of dense fog formula Carburetor (7) is opened to the starting position, press, gas integral switch (19), in electronic ignition device (5) igniting, starting air one tunnel enters fuel tank (3), fuel delivery is arrived dense fog formula Carburetor (7) lining, another road directly enters the tangential fumarole (18) of dense fog formula Carburetor (7), fuel oil forms the mist of oil of high atomisation for jet engine firing chamber (6) ignition under the effect of starting air, after the engine start, back pressure air collecting pipe (20) takes the negative-pressure gas of return-air hole (27) lining on the dense fog formula Carburetor (7) to replace starting air to continue oil dropping apparatus (3) supercharging fuel feeding; The tangential fumarole (18) of dense fog formula Carburetor (7) imported high-pressure gas by combustion gas feedback pipe (11), replace starting air to continue the fuel oil atomizing of expanding is carried out the active tangential fuel feeding that directly sprays to jet engine firing chamber (6) work overall process.Connect one-way valve (15), (17) at the supply air line first line of a couplet, stop compressed air hose and high-pressure gas pipe to collaborate mutually, leak gas; Oil pipe and tracheae connect one-way valve (14), (15), (16), (17) prevention engine gas to pipeline leakage, make and start function to start smoothly; One-way valve (12), (13) stop starting air road and back pressure air collecting pipe (20) to collaborate mutually, leak gas, and make fuel tank (3) keep certain air pressure, give dense fog formula Carburetor (7) with fuel delivery.
Fig. 3 has described the structure of dense fog formula Carburetor (7).The throttle needle-valve that throttle pintle valve seat (23) and throttle needle-valve needle body (22) are formed is housed on the carbureter body (21), and throttle pintle valve seat (23) is fastened on the carbureter body (21) with nut (24), and oil inlet hole connects oil pipe.The tangential fumarole (18) of this example is arranged on the rear of throttle pintle valve seat (23) oil outlet, and near its throttle oil outlet, opening is formed active tangential straight oil spout door together towards firing chamber direction and throttle needle-valve.Tangential fumarole (18) joins with compression ring joint (25), is fastened on the throttle pintle valve seat (23) the hole trachea of compression ring joint (25) with nut (26).The pressurized gas of tangential fumarole (18) lining ejection can act on the oil outlet of throttle needle-valve exactly with initial velocity, and do tangential motion along oil outlet, make oil circuit produce certain negative pressure, make the fuel oil of ejection change into the dense fog state with the pressurized gas expansion fog.
Fig. 3 has also described the intake valve of dense fog formula Carburetor, and intake valve is made up of valve cap (28), breathing sheet (29), valve moving plate (30), tightens together with through hole screw (31) and nut (32).Through hole screw (31) inserts the pressurized air gas circuit by one-way valve (14), replenishes starting air for Carburetor is auxiliary, and after the jet engine starting, this hole is in closed condition.
Use above-mentioned dense fog formula Carburetor and adopt pressurized gas, realize making the jet engine starting convenient, stable and reliable operation the method for the active tangential expansion atomizing fuel feeding of jet engine work overall process.
