0811402616 REXROTH比例流量閥，德國力士樂REXROTH全新原裝進口品牌備件，質量保證，現貨庫存，價格優勢供應；

定流量閥和恒流量調節閥不同的是：
1、定流量閥只有一個閥瓣，由這個閥瓣直接感受閥門的前后差壓，執行改變閥門阻力的動作，可成為“直動式變阻力閥”，它不能在線調節流量，因此使用定流量閥無法實施改變總流量的節能運行，只有在一些中央空調系統中見到。
2、恒流量調節閥是以補償方式時行變阻力的動作，它有倆個閥瓣，一個是調節閥瓣，用于補償節流孔前后的差壓，因此可成為“補償式變阻力調節閥”其原理是：利用節流孔前后的差壓，作為補償動作的驅動力，補償并保持節流孔前后差壓的穩定，從而保持流量的恒定，調節節流孔的大小就可獲得不同的流量。因此，它既可以調節流量。也可以在系統水利工況變化時保持流量恒定，在系統中它既可恒定各個支路的流量，實現流量的均衡輸配，也可以隨時改變和調節各支路的流量，實現動態平衡。如果每年在初寒到嚴寒和嚴寒到末寒是進行倆次流量調節，即可實現“分階段改變流量的質調節”的節能運行方式。恒流量調節閥的調節簡單方便，但對于較大的系統來說，每年進行倆次調節仍然是個負擔，而且恒流量調節閥的價格高，雖然當年可以收回，但對用戶仍有較大的心理壓力。

0811402616 REXROTH比例流量閥

流量閥的作用是在閥的進出口壓差變化的情況下，利用調節閥芯和閥體間的節流口面積和它所產生的局部阻力對流量進行調節，從而控制執行元件的運動速度。維持通過的流量恒定，從而維持與之串聯的被控對象(如一個環路、一個用戶、一臺設備等，下同)的流量恒定。管網中應用流量閥，可直接根據設計來設定流量，閥門可在水壓作用下，自動xc管線的剩余壓頭及壓力波動所引起的流量偏差。流量閥的名稱較多，如自力式流量平衡閥、定流量閥、動態平衡閥等。各種類型的流量閥，結構各有不同，但工作原理相似。
