自力式压力调节阀产品介绍
ZYYP型自力式压力调节阀无需外加能源,利用被调介质自身能量为动力源引入执行机构控制阀芯位置,改变两端的压差和流量,使阀前(或阀后)压力稳定。具有动作灵敏,密封性好,压力设定点波动力小等优点,广泛应用于气体、液体及蒸汽介质减压稳压或泄压稳压的自动控制。
本系列产品有单座(ZZYP)、套筒(ZZYM)、双(ZZYN)、三种结构;执行机构有薄膜式、活塞式二种;作用型式有减压用阀后压力调节(B型)和泄压用阀前压力调节(K型)。产品公称压力等级有PN16、40、64;阀体口径范围DN20~300;泄漏量等级有II级、IV级和VI级三档;流量特性为快开;压力分段调节从15~2500Kpa。可按需要组合满足用户工况要求。
自力式压力调节阀产品特点
自力式压力调节阀无需外加能源,能在无电无气的场所工作,既方便又节约了能源。
压力分段范围细且互相交叉,调节精度高。
压力设定值在运行期间可连续设定。
对阀后压力调节,阀前压力与阀后压力之比可为10:1~10:8。
橡胶膜片式检测,执行机构测精度高、动作灵敏。
采用压力平衡机构,使调节阀反应灵敏、控制精确。
