Description
Technical field
The utility model relates to the technology of gasoline engine field, particularly a kind of gasoline engine carburetor.
Background technique
Gasoline engine carburetor structure of the prior art, comprise float, float-controlled valve, the float valve seat, the float-controlled valve spring, float is connected with carburetor main body through the float pin, wherein float prolongs in float-controlled valve one side and radially is provided with opening slot, the upper end conical surface of float-controlled valve forms with the hole of float valve seat and cooperates, the lower end periphery of float-controlled valve has circular groove, the float-controlled valve spring is located in the circular groove, and the upper end of float-controlled valve spring contacts with the last section of float-controlled valve circular groove, and the last section of the opening slot on the lower end of float-controlled valve spring and the float contacts, the lower end surface of float-controlled valve circular groove contacts with the lower end surface of float opening slot, be that circular groove is stuck in the opening slot that float offers, thereby just make spring the deform gap length and the sealing of control float-controlled valve and float valve seat, make the interior oil level of float chamber maintain the scope of regulation by the float chamber Oil Level.The float-controlled valve of this structure, because the spring sky is enclosed within the float-controlled valve circular groove, the spring thread diameter is tiny, the elongated rigidity deficiency of spring, both ends of the surface contact with other part respectively and produce friction, the effect that adds frictional force makes spring be not easy return, the crooked dumb even center line of float-controlled valve action that causes takes place easily to be produced crooked, the center line of float-controlled valve does not overlap with the center line of float valve seat, make the surface of float-controlled valve and float valve seat can not form intact sealing, behind the height of oil level overshoot scope, can not complete closed because of the conical surface of float-controlled valve and float valve seat, gasoline flows out wasting problem from the nozzle of Carburetor.
The model utility content
The purpose of this utility model is to provide a kind of float-controlled valve sealing and opens that flexibility is good, reliability is high, can effectively prevent the gasoline engine carburetor that gasoline leaks from carburetor float valve, to solve gasoline waste and the environmental pollution problem that causes because of the Carburetor leakage of oil.
The technological scheme of technical solution problem is: comprise carburetor main body, float, float-controlled valve, the float valve seat, float forms flexible connection through float pin and carburetor main body, the upper end conical surface of float-controlled valve forms with the hole of float valve seat and cooperates, described float-controlled valve is provided with the interior circular hole concentric with cylindrical, the end of circular hole is provided with plug in described, be provided with the spring stationary axle in the circular hole in described, described spring stationary axle is thin ends and thick middle multidiameter shaft, the end of described spring stationary axle in interior circular hole established spring, and described spring is arranged on close plug position on the spring stationary axle, and the other end of described spring stationary axle stretches out outside the plug from the plug endoporus, the bottom periphery of described float-controlled valve is provided with circular groove, described circular groove is provided with Connection Card, and Connection Card can relatively rotate with circular groove and connect, and described float radially is provided with opening slot in float-controlled valve one side, the top of described opening slot is provided with the Connection Card fixed base, and Connection Card connects for movable with fixed base.
Described float is provided with the thin-walled projection in the edge of float-controlled valve one side.
Beneficial effect: float-controlled valve of the present utility model is provided with the interior circular hole concentric with cylindrical, the end of interior circular hole is provided with plug, be provided with thin ends and thick middle multidiameter shaft spring stationary axle in the interior circular hole, establish spring near the plug position on the spring stationary axle, the other end of spring stationary axle stretches out outside the plug from the plug endoporus, the bottom periphery of float-controlled valve is provided with circular groove, circular groove is provided with Connection Card, Connection Card can relatively rotate with circular groove and connect, float radially is provided with opening slot in float-controlled valve one side, the top of opening slot is provided with the Connection Card fixed base, and Connection Card connects for movable with fixed base.Owing to have above structural feature, fuel tank is in float chamber during oiling, after the gasoline level in the float chamber reach a certain height, thereby the gasoline floating function makes, and float rises, the fixed base on the float contact with the spring stationary axle back promote float-controlled valve move upward make that float-controlled valve contacts gradually with the sealing surface of float valve seat, gasoline continues to inject the rear spring stationary axle and overcomes spring force and make length of spring compressed and then seal the interior gasoline of rear fuel tank fully and stop to flow into float chamber, the lasting reliable sealing of the conical seal (contact) face of assurance float-controlled valve and float valve seat; When the indoor gasoline level of carburettor float is lower than limit oil level because of consumption, spring force at first makes float rotate around the float pin, fixed base on the float drives Connection Card, Connection Card drives float-controlled valve and moves downward, fixed base and spring stationary axle disengage, and the gasoline of the conical seal (contact) face of float-controlled valve and float valve seat is disengaged, fuel tank is interior flows into float chamber.This structure make float-controlled valve in sealing and opening procedure flexibility and good reliability, can effectively prevent gasoline from the gasoline engine carburetor that carburetor float valve leaks, having solved because of sealing the unreliable gasoline that causes gasoline to leak to cause wastes and environmental pollution problem.Owing to being provided with raised structures, the float rotation makes projection contact, prevent that oil level from excessively reducing to guarantee that Carburetor is to the enough fuel oils of firing chamber supply with carburetor main body after in a single day oil level is lower than a limit.
