液壓閥是一種用壓力油操作的自動(dòng)化元件，它受配壓閥壓力油的控制，通常與電磁配壓閥組合使用，可用于遠(yuǎn)距離控制水電站油、氣、水管路系統(tǒng)的通斷。常用于夾緊、控制、潤(rùn)滑等油路。有直動(dòng)型與先導(dǎo)型之分，多用先導(dǎo)型。

????液壓傳動(dòng)中用來(lái)控制液體壓力、流量和方向的元件。其中控制壓力的稱為壓力控制閥，控制流量的稱為流量控制閥，控制通、斷和流向的稱為方向控制閥。

????壓力控制閥

????按用途分為溢流閥、減壓閥和順序閥。(1)溢流閥：能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過(guò)載保護(hù)的溢流閥稱為安全閥。當(dāng)系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時(shí)，閥口會(huì)打開而溢流
