Abstract

The invention discloses a high-speed fuel gas injection electromagnetic valve for vehicles. In the invention, a part of the electromagnetic valve is sleeved in a fixed core of a magnetism conducting end cover, and one end of the outer end of the fixed core is fixedly provided with a shell of a connecting terminal, while the other end is provided with a valve seat; one end of the fixed core is connected with a gas inlet, while the other end is connected with a movable core; the interior of the fixed core is hollow, and two sides of the inner wall of the fixed core are adhered with copper pipes; an electromagnetic coil wrapped by a coil shell is wound on a coil framework fixed on the fixed core; a spring is arranged between an inner hole of the fixed core and a concave port of the movable core, and a sealing piece is fixed at the other end of the movable core; and the outer end of the movable core is provided with a valve seat, and the tail end of the valve seat is provided with a nozzle. The invention optimizes magnetic circuits, reduces the temperature raise, improves the response speed, prolongs the service life of the valve body and is easy to mass production.

Description

technical field [0001] The invention relates to a solenoid valve device for high-speed injection using LPG or CNG as fuel, in particular to a high-speed gas injection solenoid valve for vehicles. Background technique [0002] At present, the structure of the high-speed gas injection solenoid valve for vehicles is mainly composed of a fixed iron core, a moving iron core, an electromagnetic coil, a nozzle, a casing, and a valve seat. Quick break, realize high-speed operation, so as to control the high-speed injection of gaseous fuel. [0003] As in patent 200910112335.1, the solenoid valve described has a fixed iron core, the outer end of the fixed iron core is fixed with a shell, and the other end of the shell is an end cover; an electromagnetic coil is wound in the middle of the fixed iron core; The road inlet joint is fixed and connected, and the other end is sleeved with a sleeve and matched with the moving iron core. The other end of the moving iron core is fixed on the ...
