WWM6..6X型手动换向阀

该阀由阀体（1）、手柄（2）、阀芯（3）、一个或两个复位弹簧（4）和推杆（5）组成 The valve is composed of valve body (1), handle (2), valve element (3), one or two return springs (4) and push rod (5）

在非操作状态时，阀芯（3）被复位弹簧保持在中位或初始位置上。当向右或向左推动手柄（2）时，手柄（2）通过铰链推动推杆（5）并直接控制阀芯（3）.阀芯（3）便移动到要求位置，从而获得所需要的流动截面。当手柄回到零位时，控制阀芯借助复位弹簧回复到正常位置。这种阀的切换位置由手柄操纵确定 In the non operating state, the valve element (3) is held in the middle or initial position by the return spring. When the handle (2) is pushed to the right or left, the handle (2) pushes the push rod (5) through the hinge and directly controls the valve core (3). The valve core (3) moves to the required position to obtain the required flow section. When the handle returns to the zero position, the control valve core returns to the normal position with the help of the return spring. The switching position of the valve is determined by the handle operation.

WWM.../F型手动换向阀

原理与WMM…型基本相同。但这种形式的阀是有二个或三个切换位置和一个定位器的控制阀。因而所有切换位置都是固定的 The principle is basically the same as WMM... type. However, this type of valve is a control valve with two or three switching positions and a positioner. Therefore, all switching positions are fixed

插装阻尼器：由于工作条件限制切换过程中可能出现流量大于性能曲线上的数值需要采用插装阻尼器装在控制阀的P油路中 Plug in damper: due to the limitation of working conditions, the flow may be greater than the value on the performance curve, so it is necessary to install the plug in damper in the P oil circuit of the control valve

工作极限 Working limit

由于有阻塞，这类阀的工作性能与过滤精度有关。为了获得给定允许流量值  推荐采用25um的全流量过滤，阀内部的各种作用力也影响其工作极限。因此对于四通阀来说，所给出的流量数值都是两流量通道都工作的正常情形下的数值（例如由P到A并同时曲B 到T回油）Due to blockage, the working performance of this type of valve is related to the filtering accuracy. In order to obtain a given allowable flow value, it is recommended to use 25um full flow filtration, and various forces inside the valve also affect its working limit. Therefore, for four-way valve, the flow value given is the value under normal conditions when both flow channels are working (for example, oil return from P to A and simultaneously from B to T)

如果只要求一个方向流动、将四通阀的A口或B口堵塞而作为三通阀使用时．则在严重情况下其流量可能很小 If the four-way valve is used as a three-way valve with only one direction of flow and port A or port B blocked, the flow may be very small in severe cases

功能说明 Function description

WMM型阀是手柄操作方向滑阀  用以控制液流的开启、停止和换向。这种方向控制阀的组成主要包括阀体（1）、手柄（2）、控制滑阀芯（3）和1个或2个复位弹簧（4）WMM valve is a handle operated directional slide valve used to control the opening, stopping and reversing of liquid flow. The directional control valve mainly consists of a valve body (1), a handle (2), a control spool (3) and one or two return springs (4)

在非操作状态下．控制滑阀芯（3）由复位弹簧（4）保持在中位或初始位置。控制滑阀芯（3）由手柄（2）驱动。它经过一个铰接和一个销轴直接作用在控制滑阀芯（3）上。控制滑阀芯（3）因此从原始位置移动至需要的切换位置 In the non operating state, the control spool valve core (3) is held in the middle or initial position by the return spring (4). The control spool (3) is driven by the handle (2). It acts directly on the control spool (3) through a hinge and a pin. The control spool (3) therefore moves from the original position to the desired switching position

在手柄（2）回复到0切换位置后 控制滑阀芯（3）被复位弹簧（4）推回至中位。4WMM.../F...型（带定位机构），这类2个或3个切换位置和带1个定位机构的方向控制滑阀.可在所有的切换位置定位 After the handle (2) returns to the 0 switching position, the control spool valve core (3) is pushed back to the neutral position by the return spring (4). 4WMM.../F... type (with positioning mechanism), this type of directional control slide valve with 2 or 3 switching positions and 1 positioning mechanism can be positioned at all switching positions.

注意！be careful!

由于粘滞作用。该阀的切换功能取决于过滤。为了得到允许的流量数据 我们推荐过滤精度25μm全流量过滤。阀内液动力也会影响阀的性能极限 Due to adhesion. The switching function of the valve depends on filtering. In order to obtain the allowable flow data, we recommend a filtration precision of 25 μ M Full flow filtration. The hydraulic force in the valve will also affect the performance limit of the valve

对于4通阀，所示数据适用于2个方向正常流动的情况（如从P→A，同时B→T回流）◆→×见表）。如果只有单一方向流动，那么阀的性能极限会明显减小（如把4通方向阀用作3通方向阀时，油口A或B堵死）For 4-way valve, the data shown is applicable to normal flow in two directions (e.g. from P → A, while B → T returns) ◆ → × See Table). If there is only one direction of flow, the performance limit of the valve will be significantly reduced (for example, when a 4-way directional valve is used as a 3-way directional valve, port A or B is blocked)
