Y-63溢流阀减压阀/Y63_华东仪表网|上海双旭电子有限公司

Y-63溢流阀减压阀是一种低压液压系统中的压力控制元件，具有调压灵敏、安装便捷的特点。该产品采用管式连接结构，主要由阀体、阀芯、弹簧等部件组成，适用于工业液压系统中需要压力调节的场合。作为安全阀使用时，阀处于常闭状态，当系统压力超过设定值时自动开启泄压；作为溢流阀使用时，阀处于常开状态，可保持系统压力恒定。产品具有远程调压功能，可通过外接控制阀实现多级压力调节。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

产品功能特点

该阀具有多种实用功能：可作安全阀防止系统过载；作为溢流阀与节流元件并联使用时可保持系统压力稳定；支持远程调压和多级压力控制；还可作为卸荷阀使用，通过换向阀连接油箱实现油路卸荷。产品进出口设计合理，管式结构带有测量压力接口，便于系统监测和维护。适用于冶金、石化、机械制造等行业的液压系统。1 3 9

Y-63 溢流阀减压阀

一、用途

1．作安全阀时阀常闭。当阀前压力小于某调定极限值时，阀不溢流。当阀前压力超过此极限值时，阀立即打开，油液即流回油箱（或低压回路），因此能防U：液压系统过载，保护油泵和油压系统的安全。

2．作溢流阀时阀常开常溢流。该阀与节流元件及负载并联，随着工作机构需油量的不同，阀的溢油量时大时小，以调节及平衡进人液压系统中的流量，使液压系统中的压力保持恒定。板式中压溢流阀有进出口各一个，但管式中压溢淹阀有两进口及一出口。管式。板式中压溢流阀都带有一卸荷口，平时关闭，亦只有在关闭时起溢流作用。

3．远程调压。将远程调压阀进油口和溢流阀遥控口连接，在主溢流阀设定压力范围内实现远程调压。

4．高低压多级控制。用换向阀将滥流阀遥控口和几个远程调压阀连接，能在主溢流阀设定压力范围内实现高低压多级控制。

5．作卸荷阀。用换向阀将溢流阀卸荷口和油箱连接，可使油路卸荷。

6．在液压元件试验时，溢流阀也可当节流阀进行加载。

P为进油，O为同油，L为卸荷，k为远程调压，p为测量压力接口。
7．低压溢流阀用途与中压溢流阀相同，但由于无卸荷口，故不能用於远程调压与卸荷。
