博士力士乐清洗与溢流阀块的工作油口 A 与 B 都可按用户的要求,连接高压或低压油液。由高压控制的清洗滑阀,可确保在进行高-低油压端的切换时,使清洗阀可靠地与低压油口相连。 由于博士力士乐SDVB型阀块为双向作用式溢流阀采用先导控制功能,因而只需很小的操纵力就能设置油路两个高压端所需要的压力值。这些设定值的设置,可以相互独立地进行。对于规格 30 和 50 阀块,还可通过外部先导油口(X 和 Y)实现远程控制功能。一旦启动了溢流阀,高压端的液压油就可以流向低压端。设定的压力值,对应于高、低压之间的压降值。与这种阀的通流 能力相比,其结构极为紧凑。 博士力士乐SDVB型清洗与溢流阀块还可用作一种双向作用式溢流阀。在用作溢流阀 时,清洗阀的供油管路应当处于封闭状态。 采用单独或直接安装的卸载阀之后,既可以通过外部将先导阀与 油箱相连,也可以在内部与低压端相连。利用这一项功能,就可 以将 SDVB 30 和 50 用作旁通阀。对于采用SDVB 型冲洗与溢流 阀块的高动态运行,在改变了高压端之后油口A 和 B 之间仍会有 短时间的自由流动。这种应用适合使用直动式阀块;为此,我们 可根据用户要求提供 16和 30 两种规格的产品。 博士力士乐SDVB16型清洗与溢流阀块的型号说明,规格30和50见选型说明: SDVB16N1/A30A1 SDVB16N1/A30A2

设计:组合了清洗阀与溢流阀的结构设计,并由工作压力进 行控制。 安装:法兰安装,配 O 形密封圈(机罩上设有四个安装孔) 管路接口和规格:参见元件尺寸 重量(kg) 规格 16 30 50 不带底板 6,5 23 61 带底板 30 68 安装位置:可选 液流方向: 分别从 A 到 B(对应于从 B 到 A)、以及从 A 到 K 1(对应于从 B 到 K1 ) 工作压力范围: pN = 0…400 bar 只要溢流阀尚未启动,油口 XA/B 测得的压力就仅仅为工作管 路中的压力而已。而一旦先导阀开始打开阀块,主油路中的 工作压力就会上升约 15%。因此,我们建议在MA 或 MB(分 别对应于A 或 B)直接测量工作压力。 压力设定范围: 工作压力: pv min…pv max = 50…400 bar SDVB 16、30 和 50 在公称流量 qNSp 时的清洗压力:均为 无限可调。订购时,请注明要求的工作压力和清洗压力设置 值。更多详情请参见 RC 92100。 油液的温度范围: ϑm min…ϑm max = –20° C…+80° C 粘度范围: νmin…νmax = 10…1000 mm2 /s 切换压力——为了在两个方向上实现清洗阀回路 A 和 B的切换,就必须在高压 和低压端之间建立起一个压差。 这一压差、以及由此在高压端形成的切换压力,与低压端的设定 值有关。而对于 SDVB 30 和 50,还必须考虑弹簧力的作用,因 为这种作用相当于还需再上升约 9 bar 的压力,才能使阀口* 打开(参见左图)。 先导油液的zui大流量 QSt max (taken from main circuit) 规格 16 30 50 QSt max (L/min) ≈4 ≈5 ≈6 远程控制——为了能设置溢流阀的不同压力值,提供了远程控制所需要的外部先导油口"X"和"Y"。 功能型式——SDVB 16 至 50 的阀,还可作为双向作用的溢流阀使用。 如果仅仅需要双向作用的溢流阀功能, 就可以封闭清洗阀上的供 油管路, 或者将清洗阀的压力设为高于低压端的相应值即可。 博士力士乐SDVB型清洗与溢流阀块为A4VSG和A2P柱塞泵的控制元件。Rexroth清洗与溢流阀块的作用是:保持输送压力并排出多余的油液,以限制闭式液压回路中的工作压力。 博士力士乐SDVB清洗与溢流阀块还可用作一种双向作用式溢流阀。在用作溢流阀时,清洗阀的供油管路应当处于封闭状态。我公司在为您提供力士乐轴向柱塞泵的情况下,我们还为您提供该产品的控制元件——SDVB型清洗与溢流阀块。
