Technical Field
The utility model relates to a carburetor, concretely relates to dual-purpose carburetor of oil gas of idle speed stability.
Background
When the dual-purpose carburetor of oil gas is connecting the fuel and is using, because the better fuel and air mixture stability under idle state of the stability of fuel for the idle speed is reliable, and when connecting the natural gas and using, need connect the intake pipe and get into the choke, the engine needs the natural gas input that the natural gas is comparatively suitable and stable when low-speed or idle, otherwise can the idle speed unstable, because the concentration of natural gas is not too stable, and the air input can not adjust and lead to the unstable or even flame-out of engine idle speed.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide a stable dual-purpose carburetor for oil and gas with adjustable air input when using natural gas, so as to ensure the stability of the engine under low speed or idling state.
In order to achieve the above purpose, the utility model provides a following technical scheme: an oil-gas dual-purpose carburetor with stable idling comprises a carburetor body, wherein a choke is arranged on the carburetor body, a throttle valve is arranged in the choke, an air inlet pipe is arranged on the carburetor body, the outlet of the air inlet pipe penetrates through the inner wall of the throat pipe and is close to the throttle valve, a hole is drilled on the end surface of the carburetor body to form an adjusting hole, the adjusting hole is close to the throat pipe and penetrates into the inner hole of the air inlet pipe, the port of the adjusting hole on the end surface of the carburetor body is sealed by a plug body, an adjusting screw is connected on the carburetor body in a threaded manner, a plug rod is arranged at the end part of the adjusting screw, the plug rod penetrates through the adjusting hole and blocks the adjusting hole, more than one air outlet hole is arranged on the inner wall of the throat pipe, the air outlet is communicated with the adjusting hole, and the inlet end of the air outlet is arranged on the wall of the adjusting hole between the plug body and the plug rod.
The wall of the adjusting hole is provided with a butt joint groove for matching the end part of the plug rod, and the air inlet port of one air outlet hole is arranged on the butt joint groove.
The air outlet hole, the adjusting screw and the central axis between the air inlet pipes are aligned with each other.
The end face of the air inlet pipe, which is positioned in the throat pipe, is an inclined plane, and the inclined plane faces the direction of the throttle valve.
A seal ring is disposed on a circumferential surface of the adjusting screw.
The utility model discloses a this kind of structure, intake-tube connection natural gas input, the air input of regulation hole is adjusted to accessible adjusting screw's regulation, and the air inlet of regulation hole comes out from the venthole and gets into the air throttle position, like this alright adjust the entering volume of natural gas to guarantee that the engine has appropriate air input under low-speed or idle, guarantee the stability of engine operation.
The invention is further described with reference to the accompanying drawings and the detailed description.

FIG. 1 is a block diagram of an embodiment of the present invention;
fig. 2 is an enlarged view of a in fig. 1.
Detailed Description
The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1 and fig. 2, the present embodiment discloses an idling-stable dual-purpose carburetor for oil and gas, which comprises a carburetor body 1, a throat 11 is arranged on the carburetor body 1, a throttle 2 is arranged in the throat 11, an intake pipe 3 is arranged on the carburetor body 1, an outlet of the intake pipe 3 passes through the inner wall of the throat 11 and is close to the throttle 2, an adjusting hole 4 is drilled on the end surface of the carburetor body 1, the adjusting hole 4 is close to the throat 11 and penetrates into the inner hole of the intake pipe 3, so that the adjusting hole 4 is communicated with the intake pipe 3, a plug body 5 is arranged at the end of the adjusting hole 4 on the end surface of the carburetor body 1 for sealing, an adjusting screw 6 is connected to the carburetor body 1 by screw thread, a plug rod 61 is arranged at the end of the adjusting screw 6, the plug rod 61 passes through the adjusting hole 4 and seals the adjusting hole 4, two air outlets 7 are arranged on the inner wall of the throat, the inlet end of the air outlet hole 7 is arranged on the wall of the regulating hole 4 between the plug body 5 and the plug rod 61.
The hole wall of the adjusting hole 4 is provided with an abutting groove 8 for matching the end part of the plug rod 61, and an air inlet port of one air outlet hole 7 is arranged on the abutting groove 8. Such structure can make adjusting screw can not get through all ventholes 7 simultaneously in accommodation process, carries out more accurate control to 7 flow in adjacent venthole moreover to the air output of more accurate control whole natural gas.
The central axes of the air outlet hole 7, the adjusting hole 4, the adjusting screw 6 and the air inlet pipe 3 are aligned with each other. Such a structure can make the structure more reliable, has packed the stability of natural gas circulation.
The end surface of the intake pipe 3 located inside the throat 11 is an inclined surface 31, and the inclined surface 31 faces the throttle valve 2.
