0811402616 REXROTH比例流量阀，德国力士乐REXROTH全新原装进口品牌备件，质量保证，现货库存，价格优势供应；

定流量阀和恒流量调节阀不同的是：
1、定流量阀只有一个阀瓣，由这个阀瓣直接感受阀门的前后差压，执行改变阀门阻力的动作，可成为“直动式变阻力阀”，它不能在线调节流量，因此使用定流量阀无法实施改变总流量的节能运行，只有在一些中央空调系统中见到。
2、恒流量调节阀是以补偿方式时行变阻力的动作，它有俩个阀瓣，一个是调节阀瓣，用于补偿节流孔前后的差压，因此可成为“补偿式变阻力调节阀”其原理是：利用节流孔前后的差压，作为补偿动作的驱动力，补偿并保持节流孔前后差压的稳定，从而保持流量的恒定，调节节流孔的大小就可获得不同的流量。因此，它既可以调节流量。也可以在系统水利工况变化时保持流量恒定，在系统中它既可恒定各个支路的流量，实现流量的均衡输配，也可以随时改变和调节各支路的流量，实现动态平衡。如果每年在初寒到严寒和严寒到末寒是进行俩次流量调节，即可实现“分阶段改变流量的质调节”的节能运行方式。恒流量调节阀的调节简单方便，但对于较大的系统来说，每年进行俩次调节仍然是个负担，而且恒流量调节阀的价格高，虽然当年可以收回，但对用户仍有较大的心理压力。

0811402616 REXROTH比例流量阀

流量阀的作用是在阀的进出口压差变化的情况下，利用调节阀芯和阀体间的节流口面积和它所产生的局部阻力对流量进行调节，从而控制执行元件的运动速度。维持通过的流量恒定，从而维持与之串联的被控对象(如一个环路、一个用户、一台设备等，下同)的流量恒定。管网中应用流量阀，可直接根据设计来设定流量，阀门可在水压作用下，自动xc管线的剩余压头及压力波动所引起的流量偏差。流量阀的名称较多，如自力式流量平衡阀、定流量阀、动态平衡阀等。各种类型的流量阀，结构各有不同，但工作原理相似。
