德国力士乐插装阀R930055371 04020204854000A

插装阀工作原理
插装阀和其阀孔的设计通用性的重要性在于大批量生产。就某一种规格的插装阀为例,为了批量生产,其阀口的
尺寸是统一的。此外,不同功能的阀可采用同一规格阀腔,例如:单向阀、锥阀、流量调节阀、节流阀、两位电
磁阀等等。如果同一规格、不同功能的阀无法采用不同阀体,那么阀块的加工成本势必增加,插装阀的优势就不
复存在。插装阀在流体控制功能的领域的使用种类比较广泛,已应用的元件有是电磁换向阀,单向阀,溢流阀,
减压阀,流量控制阀和顺序阀。通用性在流体动力回路设计和机械实用性的延伸,充分展示了插装阀对系统设计
者和应用者的重要性。由于其装配过程的通用性、阀孔规格的通用性、互换性的特点,使用插装阀完全可以实现
完善的设计配置,也使插装阀广泛地应用于各种液压机械。

插装阀的用途
(1) 截断阀:截断阀又称闭路阀,其作用是接通或截断管路中的介质。截断阀类包括闸阀、截止阀、旋塞阀、球阀
、蝶阀和隔膜等。
(2) 止回阀:止回阀又称单向阀或逆止阀,其作用是防止管路中的介质倒流。水泵吸水关的底阀也属于止回阀类。
(3) 安全阀:安全阀类的作用是防止管路或装置中的介质压力超过规定数值,从而达到安全保护的目的
(4) 调节阀:调节阀类包括调节阀、节流阀和减压阀,其作用是调节介质的压力、流量等叁数
(5) 分流阀:分流阀类包括各种分配阀和疏水阀等,其作用是分配、分离或混合管路中的介质。

插装阀选用与应用发展
近二十年来正在迅速发展及更广泛应用的第五代液压阀种--螺纹插装阀的发展与应用。这一阀种有更明显的特色,
符合当前液压应用的发展要求,即体积小、成本低、零泄漏,插装阀的种类与功能能通过组合形式形成,开发的周期
短,因此在小于3001/min流量的应用中获得越来越广泛的应用。在选用螺纹插装阀时,应根据系统所需的流量,
大于或等于200l/min时选用二通插装阀,小于20l/min则选用螺纹插装阀。插装组件的阀芯有带尾部和不带尾部
形式,带尾部的有缓冲和节流等作用。阀芯还有多种面积比可供选择,弹簧也有多种刚度可供选择,从而实现多
种开启压力 。国内有的插装组件在阀芯和阀套之间装有O形圈,这样能确保密封,但反应速度慢。控制盖板和阀
芯中的阻尼孔有多种直径,阻尼孔大反应速度快,但冲击大,阻尼孔小则反之。如果逻辑阀的动作有先后会影响
系统的功能时,在选择阻尼孔的直径时,应特别慎重。控制盖板的型号很多,应根据系统情况仔细选择。设计阀
块时应画上盖板的定位孔,并标明各个油口的代号,以便装配和维修。应根据系统的流量和压力及其流量-压力曲
线选型,过小往往会造成系统压力损失太大,使系统发热,若选型过大,则会使系统庞大,造成经济上的浪费。
螺纹插装阀有二种密封材料可选,氟橡胶密封适用于磷酸脂介质,丁腈橡胶密封适用于矿物油介质。
螺纹插装阀由于其高压大流量的特点特别适用于阀门快速液压驱动装置,在国内外都有成熟的逻辑阀产品,其在
阀门快速液压驱动装置的应用前景是广阔的。
