An air-controlled two-way solenoid valve

Abstract

The invention discloses a pneumatic two-way solenoid valve. The pneumatic two-way solenoid valve comprises a valve body, valve core assemblies, pistons, buffer pads, valve seats, springs, a gland, filters, screw caps and an electromagnetic pilot valve; by controlling the electromagnetic pilot valve to be opened, air is controlled to enter the pistons to drive the valve core assemblies to be opened, and a liquid medium flows out from valve seats; and by controlling the electromagnetic pilot valve to be closed, the air is controlled to flow out from the pistons, the springs drive the valve coreassemblies to be closed, and the liquid medium stops flowing out from the valve seats. The pneumatic two-way solenoid valve has the characteristics of being compact in structure, capable of achievingthe double driving effect through one electromagnetic pilot valve, quick in response, capable of conducting cooling positively and the like, can be widely applied to solenoid valves, industrial control and other industries, is suitable for solenoid valves for strong oxidizing agents and strong corrosion fuel, and is especially suitable for supplying of oxidizing agents and fuel of liquid engines in the national defense field.

Description

technical field [0001] The invention relates to the technical field of solenoid valves, in particular to an air-controlled two-way solenoid valve suitable for media such as strong oxidizers and strongly corrosive fuels of liquid engines. Background technique [0002] In the solenoid valve industry for liquid engines, the solenoid valve has a complex structure and cannot be disassembled for repair; at the same time, the solenoid valves in the prior art have technical problems that cannot meet the technical problems of compact structure, one electric double action, fast response, and active cooling. Contents of the invention [0003] In view of the deficiencies in the above problems, the present invention provides an air-controlled two-way solenoid valve. [0004] In order to achieve the above object, the present invention provides an air-controlled two-way solenoid valve, including a valve body, a valve core assembly, a piston, a valve seat, a spring, a gland, a filter, a s...
