The invention relates to an isolating valve, a control method for the isolating valve and a braking system, and relates to the technical field of valve switches, the isolating valve comprises a guide sleeve, the guide sleeve is provided with a movable cavity and a valve hole communicated with the movable cavity, an armature and static iron used for limiting the armature are movably arranged in the movable cavity, and a first elastic piece is arranged between the armature and the static iron; the valve element is elastically connected with the armature through a second elastic piece; the magnet assembly is fixed to the guide sleeve, and the magnet assembly is configured to generate a magnetic field in a power-on state to promote the valve element to move in the direction away from the valve hole so as to open the valve hole; the valve core is configured to move towards the direction close to the valve hole in a power-off state so as to close the valve hole; the pressing ring and the magnet assembly are arranged on the guide sleeve in a separated mode, and the pressing ring is provided with a part at least used for extending a magnetic field magnetic line closed loop in the direction of the valve hole. The problem that in the prior art, a magnetic field generated after a valve coil is powered on is low in coverage rate in the whole moving process of an armature is solved.
本发明涉及一种隔离阀、用于该隔离阀的控制方法以及制动系统,涉及阀开关的技术领域,包括:导套,其具有活动腔以及与活动腔相连通的阀孔,活动腔内可移动地布置有衔铁,以及用于对衔铁限位的静铁,衔铁与静铁之间设有第一弹性件;阀芯,其配置为通过第二弹性件与衔铁弹性连接;磁体组件,其固定在导套上,磁体组件配置为在通电状态下,产生磁场促使阀芯朝远离阀孔方向移动,以打开阀孔;阀芯配置为在断电状态下,朝靠近阀孔方向移动,以关闭阀孔;以及压圈,其与磁体组件分离式的配置于导套上,压圈具有至少用以朝阀孔方向延伸磁场磁力线闭合回路的部分。本发明解决了现有技术中阀线圈通电后产生的磁场在衔铁整个运动过程中覆盖率较低的问题。
