電動(dòng)調(diào)節(jié)閥產(chǎn)品及廠家
流量閥的作用是在閥的進(jìn)出口壓差變化的情況下，利用調(diào)節(jié)閥芯和閥體間的節(jié)流口面積和它所產(chǎn)生的局部阻力對(duì)流量進(jìn)行調(diào)節(jié)，從而控制執(zhí)行元件的運(yùn)動(dòng)速度。維持通過(guò)的流量恒定，從而維持與之串聯(lián)的被控對(duì)象(如一個(gè)環(huán)路、一個(gè)用戶、一臺(tái)設(shè)備等，下同)的流量恒定。管網(wǎng)中應(yīng)用流量閥，可直接根據(jù)設(shè)計(jì)來(lái)設(shè)定流量，閥門可在水壓作用下，自動(dòng)消除管線的剩余壓頭及壓力波動(dòng)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
