力士乐电磁阀DZ20-1-52/50X产品的中英文介绍：

阀类型DZ是先导操作的压力顺序阀。

它用于第二系统的压力相关的连接。

压力顺序阀基本上包括具有主阀芯插入件（7）的主阀（1）和具有调节类型和可选止回阀（3）的先导控制阀（2）。

根据先导油供给和返回以及相应的功能，进行以下区分：

预装阀类型DZ。 。 -.-5X / ...（控制线4.1,12和13断开;控制线4.2,14和15闭合）

通道A中施加的压力通过控制管路（4.1）作用在先导控制阀（2）中的先导阀芯（5）上。同时，通道A中的压力通过喷嘴（6）作用在主阀芯（7）的弹簧加载侧上。如果通道P中的压力超过在弹簧（8）处设定的值，则先导阀芯（5）抵抗弹簧（8）移动。在主阀芯（7）的弹簧加载侧上的液压流体现在经由喷嘴（9），控制边缘（10）以及控制线（11）和（12）流入通道B.由此，在主滑阀（7）处发生压降。主阀芯（7）向上移动，并打开通道A至B的连接。通道A中的压力超过通道B中的值，超过弹簧（8）设置的值。在先导阀芯（5）处发生的泄漏通过先导控制阀的弹簧室（17）和控制管线（13）在内部导向通道B.如果次级回路（通道B）中的压力超过压力在通道A中，可以可选地安装止回阀（3）用于自由回流。

原则上，该阀的功能对应于DZ型的功能。 。 -.- 5X / ...。然而，对于版本“X”，打开信号经由控制线X（4.2）从外部接收。

原则上，该阀的功能对应于DZ型的功能。 。 -.- 5X / ...。然而，在版本“Y”处，在引导阀芯（5）处发生的泄漏必须通过管线（14）或（15）通过减压连接引导到罐。先导油通过管线（11）和（12）引入通道B中。

DZ型循环阀。 。 -.- 5X / .XY ...（控制线路4.2,14或15断开;控制线路4.1,12和13闭合）

原则上，该阀的功能对应于DZ型的功能。 。 -.- 5X / ...。然而，对于版本“XY”，打开信号经由控制线X（4.2）从外部接收。先导阀芯（16）孔处的先导油和发生的泄漏必须通过管线（14）或（15）通过减压连接被引导到油箱。

The valve type DZ is a pilot-operated pressure sequence valve.

It is applied for pressure-dependent connection of a second system.

The pressure sequence valve basically consists of main valve (1) with main spool insert (7) and pilot control valve (2) with adjustment type and optional check valve (3). 

According to the pilot oil supply and return and the respective function, the following differentiation is made: 

Preload valve type DZ. . -.-5X/… (control lines 4.1, 12 and 13 open; control lines 4.2, 14 and 15 closed) 

The pressure applied in channel A acts via the control line (4.1) on the pilot spool (5) in the pilot control valve (2). Simultaneously, the pressure in channel A acts via the nozzle (6) on the spring-loaded side of the main spool (7). If the pressure in channel P exceeds the value set at the spring (8), the pilot spool (5) is moved against the spring (8). The hydraulic fluid on the spring-loaded side of the main spool (7) now flows via the nozzle (9), the control edge (10) and control lines (11) and (12) into channel B. Due to this, a pressure drop occurs at the main spool (7). The main spool (7) is moved upwards and opens the connections from channel A to B. The pressure in channel A exceeds the value in channel B by the value set at the spring (8). The leakage occurring at the pilot spool (5) is directed internally via the spring chamber (17) of the pilot control valve and the control line (13) into channel B. If the pressure in the secondary circuit (channel B) exceeds the pressure in channel A, a check valve (3) may be optionally installed for free return flow. 

Preload valve type DZ. . -.-5X/.X… (control lines 4.2, 12 and 13 open; control lines 4.1, 14 and 15 closed) 

In principle, the function of this valve corresponds to the function of type DZ. . -.-5X/…. With version "X", however, the opening signal is received externally via control line X (4.2). 

Sequence valve type DZ. . -.-5X/.Y… (control lines 4.1, 12 and 14 or 15 open; control lines 4.2 and 13 closed) 

In principle, the function of this valve corresponds to the function of type DZ. . -.-5X/…. At version "Y", however, the leakage occurring at the pilot spool (5) has to be directed via line (14) or (15) to the tank by means of a depressurized connection. The pilot oil is directed via line (11) and (12) into channel B. 

Circulation valve type DZ. . -.-5X/.XY… (control lines 4.2, 14 or 15 open; control lines 4.1, 12 and 13 closed) 

In principle, the function of this valve corresponds to the function of type DZ. . -.-5X/…. With version "XY", however, the opening signal is received externally via control line X (4.2). The pilot oil at the pilot spool (16) bore and occurring leakage have to be directed via line (14) or (15) to the tank by means of a depressurized connection.
