Y-63溢流閥減壓閥是一種低壓液壓系統(tǒng)中的壓力控制元件，具有調(diào)壓靈敏、安裝便捷的特點。該產(chǎn)品采用管式連接結構，主要由閥體、閥芯、彈簧等部件組成，適用于工業(yè)液壓系統(tǒng)中需要壓力調(diào)節(jié)的場合。作為安全閥使用時，閥處于常閉狀態(tài)，當系統(tǒng)壓力超過設定值時自動開啟泄壓；作為溢流閥使用時，閥處于常開狀態(tài)，可保持系統(tǒng)壓力恒定。產(chǎn)品具有遠程調(diào)壓功能，可通過外接控制閥實現(xiàn)多級壓力調(diào)節(jié)。1 10

Product Introduction of Y-63 Pressure Relief Valve

The Y-63 pressure relief valve is a pressure control component commonly used in low-pressure hydraulic systems. With sensitive pressure adjustment and convenient installation features, it adopts a threaded connection structure and consists of valve body, spool, spring and other components. When functioning as a safety valve, it remains normally closed and opens automatically when system pressure exceeds the set value. As a relief valve, it stays normally open to maintain constant system pressure. The product supports remote pressure adjustment and multi-stage pressure control through external valves.1 5

產(chǎn)品功能特點

該閥具有多種實用功能：可作安全閥防止系統(tǒng)過載；作為溢流閥與節(jié)流元件并聯(lián)使用時可保持系統(tǒng)壓力穩(wěn)定；支持遠程調(diào)壓和多級壓力控制；還可作為卸荷閥使用，通過換向閥連接油箱實現(xiàn)油路卸荷。產(chǎn)品進出口設計合理，管式結構帶有測量壓力接口，便于系統(tǒng)監(jiān)測和維護。適用于冶金、石化、機械制造等行業(yè)的液壓系統(tǒng)。1 3 9

Y-63 溢流閥減壓閥

一、用途

1．作安全閥時閥常閉。當閥前壓力小于某調(diào)定極限值時，閥不溢流。當閥前壓力超過此極限值時，閥立即打開，油液即流回油箱（或低壓回路），因此能防U：液壓系統(tǒng)過載，保護油泵和油壓系統(tǒng)的安全。

2．作溢流閥時閥常開常溢流。該閥與節(jié)流元件及負載并聯(lián)，隨著工作機構需油量的不同，閥的溢油量時大時小，以調(diào)節(jié)及平衡進人液壓系統(tǒng)中的流量，使液壓系統(tǒng)中的壓力保持恒定。板式中壓溢流閥有進出口各一個，但管式中壓溢淹閥有兩進口及一出口。管式。板式中壓溢流閥都帶有一卸荷口，平時關閉，亦只有在關閉時起溢流作用。

3．遠程調(diào)壓。將遠程調(diào)壓閥進油口和溢流閥遙控口連接，在主溢流閥設定壓力范圍內(nèi)實現(xiàn)遠程調(diào)壓。

4．高低壓多級控制。用換向閥將濫流閥遙控口和幾個遠程調(diào)壓閥連接，能在主溢流閥設定壓力范圍內(nèi)實現(xiàn)高低壓多級控制。

5．作卸荷閥。用換向閥將溢流閥卸荷口和油箱連接，可使油路卸荷。

6．在液壓元件試驗時，溢流閥也可當節(jié)流閥進行加載。

P為進油，O為同油，L為卸荷，k為遠程調(diào)壓，p為測量壓力接口。
7．低壓溢流閥用途與中壓溢流閥相同，但由于無卸荷口，故不能用於遠程調(diào)壓與卸荷。
