Z1S型单向阀是叠加式结构的单向阀。此型阀主要包括阀体（1）和单向阀插装件（2）Z1S one-way valve is a one-way valve with a superimposed structure. This type of valve mainly includes valve body (1) and one-way valve insert (2)

单向阀在一个方向上无泄漏地封闭.而在另一个方向上则允许自由流通 The check valve is sealed without leakage in one direction and allows free flow in the other direction

内孔中锥阀（3）的行程受到弹簧座（4）的限制。内装弹簧（5）使锥阀（3）闭合并使其保持在闭合的位置上 The travel of the poppet (3) in the bore is limited by the spring seat (4). The built-in spring (5) closes the conical valve (3) and keeps it in the closed position

Z2S10型单向阀是叠加式液控单向阀。它可以用于关闭一个或二个工作油口，无泄漏持续时间长，稳定性好。油液可以由A1至A2或B1至B2自由流动.而反方向则封闭 Z2S10 one-way valve is a superimposed hydraulic control one-way valve. It can be used to close one or two working oil ports, with long leak free duration and good stability. Fluid can flow freely from A1 to A2 or B1 to B2. The opposite direction is closed

当油液由A1至A2.压力油作用在阀芯（1）上.阀芯则向右运动并推动钢球（2）离开阀座。单向阀（3）被控制油打开时 油液可以从B2流向B1 压力油在B2腔卸荷 单向阀（3）全部打开 When the fluid is from A1 to A2, the pressure oil acts on the valve element (1) The valve core moves to the right and pushes the steel ball (2) away from the valve seat. When the check valve (3) is opened by the control oil, the oil can flow from B2 to B1. The pressure oil unloads the check valve (3) in the B2 chamber

为保证两个单向阀在换向中位时可靠的关闭，阀的A1 B1口与回油路连接 In order to ensure that the two check valves can be reliably closed when they are in the reverse position, the A1 B1 port of the valve is connected with the return oil circuit
