A pressure reducing valve control circuit and its control method

Abstract

The invention discloses a pressure reducing valve control circuit and a control method thereof. The control circuit comprises an operating switch, a rectifier bridge, a valve change-over switch and a charge coil, wherein the charge coil is connected with a storage battery through the rectifier bridge; the operating switch is separately connected with a relay of a starting motor, an electromagnetic valve of a carburetor, the valve change-over switch and a flameout end of a high-voltage set; the relay of the starting motor and the electromagnetic valve of the carburetor are connected with an anode of the storage battery; and the valve change-over switch is in linkage connection with a microswitch of a pressure reducing valve. According to the control method of the pressure reducing valve control circuit, corresponding fuels are selected through the valve change-over switch, when the valve change-over switch rotates to a corresponding position, the corresponding microswitch is triggered, switch-on and switch-off of the electromagnetic valve connected with the microswitch are controlled, then switch-on and switch-off of an oil line of the carburetor can be controlled, and the circumstance that fuel oil in the carburetor combusts to cause unstable running of an engine is avoided; and by switching of different states of the operating switch, three states including starting, flameout and working of a generator are realized.

Description

technical field [0001] The invention relates to a pressure reducing valve control circuit and a control method thereof, belonging to the technical field of generators. Background technique [0002] The carburetor is a mechanical device that mixes gasoline with air in a certain proportion under the vacuum generated by the engine. As a precise mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to realize the atomization of gasoline. . The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to keep the outlet pressure automatically stable. At present, the carburetor is generally directly connected to the pressure reducing valve through the breather pipe, and the passage of oil and gas is switched manually. In the actual operation process, the user is prone to misoperation, and the mixture of oil and gas is supplied to the engine,...

Problems solved by technology

At present, the carburetor is generally directly connected to the pressure reducing valve through the breather pipe, and the passage of oil and gas is switched manually. In the actual operation process, the user is prone to misoperation, and the mixture of oil and gas is supplied to the engine, resulting in poor engine performance. Stable; in addition, because there is no corresponding control circuit, the fuel inside the carburetor will participate in the combustion, which will also cause the engine to run unstable
