Z2S10-1-3X REXROTH单向阀

单向阀是气流只能一个方向流动而不能反向流动的方向控制阀。其工作原理与液压单向阀一样。压缩空气从P口进入，克服弹簧力和摩擦力使单向阀阀口开启，压缩空气从P流至A；当P口无压缩空气时，在弹簧力和A口(腔)余气力作用下；阀口处于关闭状态，使从A至P气流不通。单向阀应用于不允许气流反向流动的场合，如空压机向气罐充气时，在空压机与气罐之间设置一单向阀，当空压机停止工作时，可防止气罐中的压缩空气回流到空压机。单向阀还常与节流阀、顺序阀等组合成单向节流阀、单向顺序阀使用。

(单向阀)止回阀用途广泛，有很多种类，下面说的是供水和热力常用的止回阀：

1、弹簧式：液体由下而上，依靠压力顶起弹簧控制的阀瓣，压力消失后，弹簧力将阀瓣压下，封闭液体倒流。常用于通径较小的止回阀。

2、重力式：和弹簧式相似，依靠阀瓣的自身重力封闭，防止倒流。

3、旋启式：液体在阀体内直通，依靠压力顶开一侧的旋转阀瓣，压力失去后，阀瓣依靠自重回位，反向的液体压力封闭阀瓣。

4.塑料隔膜式: 外壳和隔膜均为塑料.一般外壳为ABS,PE,PP,NYLON, PC.隔膜有硅树脂,氟树脂等。

其它的单向阀（止回阀），如排污的止回阀，人防的防爆阀和液体使用的止回阀的原理是大同小异。

节流阀和单向节流阀是简易的流量控制阀，它们在定量泵液压系统中的主要作用是与溢流阀配合，组成三种节流调速系统：即进油节流调速系统、回油节流调速系统和旁路节流调速系统。对于执行元件要求往返节流调速的系统可使用两个单向节流阀。节流阀也在容积节流调速回路中使用。这种阀没有压力及温度补偿装置，不能自动补偿载荷及油液粘度变化时造成的速度不稳定，但其结构简单，制造和维护方便。所以在载荷变化不大或对速度稳定性要求不高的一般液压系统中得到广泛应用。

锻压机床

锻压机床是金属和机械冷加工用的设备，他只改变金属的外形状。锻压机床包括卷板机，剪板机，冲床，压力机，液压机，油压机，折弯机等。

液压机是一种以液体为工作介质，根据帕斯卡原理制成的用于传递能量以实现各种工艺的机器。液压机一般由本机（主机）、动力系统及液压控制系统三部分组成。液压机分类有阀门液压机，液体液压机，工程液压机。

液压机（又名：油压机）液压机是一种利用液体静压力来加工金属、塑料、橡胶、木材、粉末等制品的机械。它常用于压制工艺和压制成形工艺，如：锻压、冲压、冷挤、校直、弯曲、翻边、薄板拉深、粉末冶金、压装等等。

它的原理是利用帕斯卡定律制成的利用液体压强传动的机械，种类很多。当然，用途也根据需要是多种多样的。如按传递压强的液体种类来分，有油压机和水压机两大类。

Z2FS...型双单向节流阀

1.结构分析

Z2FS16型阀是叠加式设计的双路单向节流阀。该阀用于限制来自一个或两个工作油口的主流量或控制流量。

两个对称设置的单向节流阀在一个方向上限定流量,(通过调整节流阀芯),在相反方向上允许自由流通。用于进口节流控制时, 油液从油口A流经节流口( 1 )到达工作油口。节流阀芯( 4.1 )可借助于调节螺钉( 5 )进行轴向调整,从而可以设定节流口(1 )同时,油口A中的油液通经道( 2 )到节流阀芯( 4.1 )的弹簧加载侧(3 )产生的压力与弹簧

共同作用,使节流阀芯( 4.1 )保持在节流位置,

油液从执行器回流推动节流阀芯( 4.2 ),允许油液自由流过。此时阀作为单向阀工作。根据型号(S或S2 ),节流口可以起进口或出口节流的控制作用。限制主流量为了改变执行器的速度(主流量限制),双路单向节流阀是而安装于方向控制阀和底板之间。限制控制流量对液控方向阀,双路单向节流阀用作控制阻尼调节,在此情况下,它被安装于主阀和控制阀之间。

液压油箱在液压系统中的主要作用为储油、散热、分离油中所含空气及泡沫。选用油箱首先要考虑其容

量，一般移动式设备取泵大流量的2～3倍，固定式设备取3～4倍；其次考虑油箱油位，当系统全部液压油缸伸出后油箱油面不得低于低油位，当油缸回缩以后油面不得高于高油位；后考虑油箱结构，传统油箱内的隔板并不能起沉淀脏物的作用，应沿油箱纵轴线安装一个垂直隔板。此隔板一端和油箱端板之间留有空位使隔板两边空间连通，液压泵的进出油口布置在不连通的一端隔板两侧，使进油和回油之间的距离远，液压油箱多起一些散热作用。
