ZZYM自力式压力调节阀 ZZYMSelf-OperatedPressureRegulatingValve

ZZYM系列调节阀采用外取压结构，能依靠介质自身压力变化达到自动调节和稳定压力的目的。该产品最大特点，能在无电、无气的场所工作，是一种节能产品。压力设定值可在运行中随意调整。常规产品采用快开流量特性，亦可采用线性、等百分比流量特性。动作灵敏，减压比一般情况下最大可达10，最小为1.25，广泛应用于石油、化工、电力、冶金、食品、轻纺、居民楼群等各种工业设备中清洁的气体、液体、蒸汽等介质，高压差 \triangle{P\ge1M{pa}} 和 {\bf D N}{<=}100 以及 {\bf D N}>100 工况下减压、稳压(用于控制阀后压力)的自动控制,调节精度优于ZZYN。

The ZZYM series of regulating valves utilize an extenal pressure-taking structure, enabling automatic adjustment and pressure stabilizationbased on changes in the medium's own pressure.A prominent feature of this product is its ability to operate in locations without electricity or pneumatic power, making it an energy-saving option The presure setpoint canbe adjusted freely during operation. Standard products incorporate aquick-opening flowcharacteristic, with options forlinear and equal percntage lowcharacteristics as wellThealves areresponsive, with a pressure reductin ratio that typically ranges from a minimum of 1.25 to a maximum of 10. They are widely used in various industrial equipment, inldin the thlem, hmical, pwer,metalrical fd, txtile an reientialuilin et for cleangas, lqids steam andoh ediaThar partiuarlyuitablefratatic conlfpresue retn and stabilization (to control the downstream pressure) under conditions of high pressure difference ( \mathbf{\triangleP\ge1Mpa)} and pipe diameters of DN<=100 as well as DN>100 The regulation accuracy of this series is superior to that of the ZZYN series.

该系列只有阀后式ZZYM-oB一种。

This series only includes one type: the downstream positioned ZZYM-B.
