Double-loop electromagnetic intelligent conversion heater

Abstract

The invention discloses a double-loop electromagnetic intelligent conversion heater, and relates to a diesel tank electromagnetic valve automatic conversion device in the field of engines, the double-loop electromagnetic intelligent conversion heater comprises an electromagnetic valve main body, a heater main body heating part is fixedly connected below the electromagnetic valve main body, and a smooth oil duct is arranged in the electromagnetic valve main body; a first valve element and a second valve element are slidably connected into the smooth oil way. The oil tank conversion electromagnetic valve and the oil tank heater are combined into a whole, the problem that when an original electromagnetic valve is below-20 DEG C in winter, diesel oil is crystallized and waxed to cause opening failure of the electromagnetic valve is mainly solved, the space occupied by the oil tank conversion electromagnetic valve is reduced, installation is fast, the electromagnetic conversion valve of the heater is purchased, and the installation cost is saved; the device is controlled through an electronic element, high-grade fuel oil is manually switched through a button, 0 # diesel oil is automatically controlled to be switched through a temperature sensor, seamless connection is achieved in the switching process, and a guarantee is added for vast drivers in cold winter through perfect maneuverability and flexibility of the device.

Description

technical field [0001] The invention relates to an automatic switching device for a solenoid valve of a diesel tank in the field of engines, in particular to a dual-circuit electromagnetic intelligent switching heater. Background technique [0002] Some trucks are equipped with two fuel tanks, the main fuel tank and the auxiliary fuel tank, or one fuel tank is divided into the main chamber and the auxiliary chamber. The main fuel tank should be filled with 0# diesel oil, and the auxiliary fuel tank should be filled with high-grade diesel oil. These two fuel tanks are connected to the engine through the oil circuit. , the main fuel tank meets the manual switching valve through the heater and the auxiliary fuel tank. When starting the vehicle, use high-grade diesel oil and the vehicle is running normally. Wait for the water temperature in the heater to rise above 60°C. You need to stop and manually switch the switching valve to switch the high-grade oil. To run the vehicle wit...

[0002] Some trucks are equipped with two fuel tanks, the main fuel tank and the auxiliary fuel tank, or one fuel tank is divided into the main chamber and the auxiliary chamber. The main fuel tank should be filled with 0# diesel oil, and the auxiliary fuel tank should be filled with high-grade diesel oil. These two fuel tanks are connected to the engine through the oil circuit. , the main fuel tank meets the manual switching valve through the heater and the auxiliary fuel tank. When starting the vehicle, use high-grade diesel oil and the vehicle is running normally. Wait for the water temperature in the heater to rise above 60°C. You need to stop and manually switch the switching valve to switch the high-grade oil. To run the vehicle with 0# diesel oil, it is necessary to manually switch to high-grade oil to run for more than 1 minute before the vehicle stops working, and then stop the engine, which is very cumbersome to use

[0003] In the later period, a single fuel tank switching solenoid valve was invented to switch between the main fuel tank and the auxiliary fuel tank. The single fuel tank switching solenoid valve can be switched manually without parking. It only needs to press the switching button in the cab, but due to its large size , takes up a lot of space, and is usually installed at a distance between the frame and the fuel tank heater. When the ambient temperature is too low, the low-grade oil will circulate in the oil circuit and lose temperature, which will easily cause the fuel tank switching solenoid valve to hang wax and get stuck. Unable to switch the fuel of the main and auxiliary fuel tanks normally
