先导式顺序阀(切断型).PDFVIP

LSQDB 工作OPERATION 先导式顺序阀( 切断型) Kick-down sequence valves will kick completely open and remain open once the pressure at the inlet(port ① )exceeds the valve setting, creating an unrestricted flow path from ① to ② (sequence). The pressure setting at port ① is relative to the drain 说明DESCRIPTION (port ③ ). The valve remains open as long as the pressure at port ① exceeds the A cartridge-style kick-down pilot- pressure at port ②. To reset the valve, pressure at port ①must fall below the setting operated spool-type sequence of the valve, flow from ① to ② must cease; pressure at port ② must be equal to or valve with internal pilot and greater than the pressure at port ①． spring chamber drain 一旦进油口( 油口①) 的压力超过阀设定值，切断型顺序阀将会开启，并保持开启的状 内控内排，切断型先导式顺序阀 态，从而实现油口①到油口②自由流通。油口①的设定压力与外泄口( 油口③) 压力有 关。当油口①的压力超过油口②，阀门将一直处于开启状态。仅在油口① 的压力低于 阀的设定压力基础上，油口①到油口②无油液流动，或者油口②的压力大于等于油口 ①的压力，此阀才能复位。 特性FEATURES • Should not be used in load holding applications. 不应该在有保压要求工况中使用； • The main stage orifice is protected by a 150 micron stainless steel screen. 主油孔通过一个150 微米的不锈钢过滤器来保护； • Pressure at port ③ is directly additive to the valve setting at a 1:1 ratio and should SYMBOL not exceed 5000 psi (350 bar). 油口③的压力按1:1 叠加到阀的设定值上，且不应该超过5000 psi ； • Intended for use on the actuator side of the system as flow through the valve must cease for the v
