Abstract

一种永磁电磁阀，它包括阀体，阀体内阀芯，阀芯端部的永磁体，阀体与阀芯间的弹簧，密封圈连接于阀体与接头间，阀体上绕有线圈；当线圈通电时，螺旋线圈产生磁力与永磁体相作用，使永磁体左移动，推动阀芯并压缩弹簧使左边阀体阀口闭合，右边接头阀口打开；当断开线圈电源时，线圈磁力消失，阀芯在弹簧力作用下向右移动封住接头阀口，同时左边阀体阀口打开。本发明去除了常用电磁阀的铁芯与软磁性接头结构，利用永磁体强磁性特性，使电磁阀结构简单，稳定，可靠。

Description

永磁电磁阀
技术领域
本发明涉及一种阀门，具体说是一种电磁阀。
背景技术
电磁阀是利用通电线圈激励产生电磁力，驱动阀芯运动，以开启或关闭阀门，改变流体的流动方向。电磁阀在流体的自动控制及远程控制当中的应用十分广泛。在普通的电磁阀中，通常设置有铁芯与端部软磁体。其结构比较复杂，作用力小，稳定性差，使用中容易发生故障。
发明内容
为了从根本上克服传统电磁阀的结构复杂，稳定性差，作用力小等缺点，本发明提供一种结构简单，稳定可靠，应用更广的新型电磁阀。
本发明为实现上述目的所采用的技术方案是：一种永磁电磁阀，它包括阀体，阀体内阀芯，阀芯端部的永磁体，阀体与阀芯间的弹簧，密封圈连接于阀体与接头间，阀体上绕有线圈；当线圈通电时，螺旋线圈产生磁力与永磁体相作用，使永磁体左移动，推动阀芯并压缩弹簧使左边阀体阀口闭合，右边接头阀口打开；当断开线圈电源时，线圈磁力消失，阀芯在弹簧力作用下向右移动封住接头阀口，同时左边阀体阀口打开。
所述永磁体采用永磁材料做成；阀体，阀芯，密封圈，接头采用非磁性材料做成。
所述阀芯在磁力作用下可密封阀体阀口；阀芯在弹簧力作用下可密封接头阀口。
所述密封圈连接于阀体与接头间，起加强密封作用。
本发明利用永磁体对电磁力相作用的特性，通过开关电源，使线圈通电与不通电，使电磁力产生或消失，在弹簧力的作用下实现阀芯的往复移动，从而实现对电磁阀口的封闭与打开，实现电磁阀门的开合功能。本发明去除了传统电磁阀的铁芯与软磁体结构，利用永磁体强磁力性特征，从而提高了作用力的效率，提高了可靠性，简化结构，节约了成本。
附图说明
图1是本发明的永磁电磁阀的剖面图。
具体实施方式
本发明的永磁电磁阀的结构如图1所示，一种永磁电磁阀，它包括阀体1，阀体1内阀芯2，阀芯2端部的永磁体3，阀体1与阀芯2间的弹簧4，密封圈5连接于阀体1与接头6间，阀体1上绕有线圈7；当线圈7通电时，螺旋线圈7产生磁力与永磁体3相作用，使永磁体3左移动，推动阀芯2并压缩弹簧4使左边阀体1阀口闭合，右边接头6阀口打开；当断开线圈7电源时，线圈7磁力消失，阀芯2在弹簧4力作用下向右移动封住接头6阀口，同时左边阀体1阀口打开。本发明利用永磁体对电磁力相作用的特性，通过开关电源，使线圈7通电与不通电，使电磁力产生或消失，在弹簧4力的作用下实现阀芯2的往复移动，从而实现对电磁阀口的封闭与打开，实现电磁阀门的开合功能。本发明去除了传统电磁阀的铁芯与软磁体结构，利用永磁体强磁力性特征，从而提高了作用力的效率，提高了可靠性，简化结构，节约了成本。
