Abstract

The invention provides a straight-through type variable flow electromagnetic control valve. The straight-through type variable flow electromagnetic control valve comprises an outer shell, a main valve body, a valve element assembly and a coil assembly. A left valve seat is arranged at the middle portion of the main valve body and made of magnetism isolation materials and divides the main valve body into a left part and a right part. A right valve seat is arranged at the medium outlet end of the main valve body. The valve element assembly comprises a left valve element, a left valve element spring, a right valve element and a right valve element spring. The coil assembly comprises a left coil used for controlling the left valve element and a right coil used for controlling the right valve element. The left valve seat, the right valve seat, the left valve element and the right valve element are provided with medium circulation holes. The right valve seat is provided with a throttling hole, one end of the throttling hole communicates with a medium cavity between the right valve seat and the right valve element, and the other end of the throttling hole communicates with the medium circulation hole in the right valve seat. By means of the straight-through type variable flow electromagnetic control valve, flow can be adjusted, and switching of two flow points is achieved.

Description

technical field [0001] The invention relates to a variable flow electromagnetic control valve, in particular to a discontinuous flow electromagnetic control valve, which can be used as a medium flow control valve in equipment such as two-stage variable thrust engines. Background technique [0002] A typical solenoid valve is usually used as a medium on-off control valve, which has the characteristics of simple structure, easy control, and high reliability, but it cannot achieve flow regulation. [0003] Existing flow regulating valves can regulate the flow, but their structures are relatively complex, their reliability is low, and they cannot meet the design requirements in some applications. For example, a variable thrust engine in a power system needs to be equipped with a control valve that can adjust the flow rate. It is required that the fuel flow rate can be switched between two specified flow points under the working pressure, and the control valve is required to be c...
