An electromagnetic actuator installed in a high-pressure gas integrated bottle valve

Abstract

The invention relates to an electromagnetic actuator mounted on a high-pressure gas integrated cylinder valve. The electromagnetic actuator comprises a shell assembly, a pilot head assembly (1), an electromagnetic coil (4), an armature assembly (6) and an end cover (8). A gas flow channel is formed in the axial direction of the pilot head assembly (1). One end of the pilot head assembly (1) is used for being connected with the integrated cylinder valve in a butt joint mode, and the other end of the pilot head assembly (1) is movably connected with one end of the armature assembly (6). The other end of the armature assembly (6) is connected with one end of the end cover (8) through an elastic structure, and the other end of the end cover (8) is fixedly connected with the shell assembly. The electromagnetic coil (4) is wound outside the armature assembly (6) and the end cover (8), and the shell assembly wraps the pilot head assembly (1) and the electromagnetic coil (4). Compared with the prior art, the electromagnetic actuator has the advantages of being good in airtightness, controllability and stability, high in reliability and long in service life.

Description

technical field [0001] The invention relates to an electromagnetic actuator, in particular to an electromagnetic actuator installed on a high-pressure gas integration bottle valve. Background technique [0002] With the development of fuel cell vehicles in the world, more and more companies have developed or are developing high-pressure gas storage and filling technology. Due to the successful development of the 70MPa vehicle-mounted gas storage cylinder by the Canadian company Dynetek and the launch of the 70MPa gas filling gun by the German company WEH, the It is possible to apply the storage and filling technology of 70MPa gas to fuel cell vehicles. [0003] Due to the requirements of the working conditions of fuel cell vehicles, the high-pressure gas storage cylinder valve as the fuel tank output controller needs to have more functions and needs to be connected to the control system of the vehicle, so the traditional manual control cylinder valve is no longer It can mee...

Problems solved by technology

[0003] Due to the requirements of the working conditions of fuel cell vehicles, the high-pressure gas storage cylinder valve as the fuel tank output controller needs to have more functions and needs to be connected to the control system of the vehicle, so the traditional manual control cylinder valve is no longer It can meet the requirements of automobiles, and the integrated integrated bottle valve has become the mainstream bottle valve for gas storage cylinders of fuel cell vehicles. This bottle valve is a multifunctional integrated bottle valve that integrates electromagnetic actuators, filters, combined Safety pressure relief device, pressure sensor, temperature sensor, overvoltage protector, etc.
