調(diào)壓閥AP71S MV4-FV6-FV4 FV4原裝供應(yīng)
APTECH調(diào)壓閥是通過調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。
