| REXROTH力士乐液压顺序阀工作原理DBDS6P18/400价格 | |
| 根据液压顺序阀工作原理： 按工作原理和结构，顺序阀分直动式和先导式两类； 按压力控制方式，顺序阀有内控和外控之分。 在顺序阀中装有单向阀，能通过反向液流的复合阀称为单向顺序阀。一般说来，这种阀使用较多。 功能及应用：顺序阀的基本功能是控制多个执行元件的顺序动作，根据其功能的不同，分别称为顺序阀、背压阀、卸荷阀和平衡阀。 顺序阀的性能与溢流阀基本相同，但由于功能的不同，对顺序阀还有其特殊的要求： a.为了使执行元件准确实现顺序动作，要求顺序阀的调压精度高，偏差小； b.为了顺序动作的准确性，要求阀关闭时内泄漏量小； c.对于单向顺序阀，要求反向压力损失及正向压力损失值均应较小。 顺序阀的主要作用有： a.控制多个元件的顺序动作； b.用于保压回路； c.防止因自重引起油缸活塞自由下落而做平衡阀用； d.用外控顺序阀做卸荷阀，使泵卸荷； e.用内控顺序阀作背压阀。 2、生产顺序阀产品厂家：国内主要是榆次液压集团有限公司、北京华德液压集团有限公司、上海立新液压件厂等。国外有美国Vickers、德国Rexroth等厂家。 3、顺序阀的选用：顺序阀根据装配结构的不同，可以实现不同的回路功能，如溢流阀、顺序阀和平衡阀的功能。 顺序阀的启闭特性如果太差，则流量较大时一次压力过高，回路效率降低。启闭特性带有滞环，开启压力低于闭合压力，负载流量变化时应予注意。开启压力过低的阀，再压力低于设定压力时发生前漏，引起执行器误动作。通过阀的流量远小于额定流量时，产生振动或其他不稳定现象。此时要再回路上采取措施。DBDS6P18/400价格 | |
