Abstract

The invention discloses a two-position two-way normally closed type miniature high-flow fuel electromagnetic valve which is characterized by comprising a valve body assembly. The valve body assembly comprises an inner valve body, an outer valve body is arranged on the outer side of the inner valve body, a movable door mounting chamber is arranged between the two valve bodies, a movable door is arranged in the movable door mounting chamber, the inside of the movable door and the inside of the inner valve body are of hollow structures, an inlet is formed in the head of the outer valve body, a first hole is formed in the rear of the inlet, directly faces the movable door and is communicated with a control cavity, the control cavity is formed inside the movable door and the inner valve body, and is communicated with an ejector rod mounting chamber via a second hole formed in the inner valve body, the head of the ejector rod mounting chamber is communicated with a fourth hole in the outer valve body via a third hole in the inner valve body, the movable door mounting chamber is arranged between the inner valve body and the outer valve body, a fifth hole is formed in the outer valve bodyand is particularly formed in a position next to the movable door mounting chamber, and the inner valve body, the movable door and the outer valve body are in clearance fit with one another. The two-position two-way normally closed type miniature high-flow fuel electromagnetic valve has the advantages of small volume, light weight, high-voltage resistance, high flow and reliability, low starting energy consumption and the like.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to a two-position, two-position, normally-closed miniature large-flow fuel electromagnetic valve. Background technique [0002] The fuel adjustment system in the hydraulic system has the advantages of simple structure, high reliability, and good environmental adaptability. Especially in harsh environments such as flammable, explosive, radiation, and vibration, in aviation, ships, and some special fields, fuel oil Regulation systems are widely used. As an important control element of the fuel regulating system, the reliability requirements of the solenoid valve are continuously improved with the development and improvement of the fuel system, and are developing in the direction of high reliability, miniaturization and light weight. However, the large-flow solenoid valves currently on the market under high-pressure conditions generally have problems such as large volume, heavy weight, and ...
