(L型)角式隔膜阀
简要描述：RETZ进口L型，角式隔膜阀在阀体和阀盖内装有一挠性隔膜或组合隔膜，其关闭件是与隔膜相连接的一种压缩装置。阀座是堰形，其操纵机构与介质通路隔开，不但保证了工作介质的纯净，同时也防止管路中介质冲击操纵机构工作部件的可能性
品牌：RETZ- 工况条件：开/关
- 温度/压力：P-T:16bar-80℃

(L型)进口角式隔膜阀特点∶ Performance characteristics 
1.气密性优异 Excellent air tightness
驱动部通过隔膜隔离，因此无球阀、蝶阀之类的填料压盖部，无外部泄漏或外界空气进入污染流体 The driving part is isolated by diaphragm, so there is no packing gland part such as ball valve and butterfly valve, and there is no external leakage or external air entering the polluted fluid
2.阀座零泄漏 Zero leakage of valve seat
可挠性隔膜将流体隔断，因此阀座无泄漏 The flexible diaphragm blocks the fluid, so the valve seat has no leakage
采用橡胶隔膜时，即使流体内有些异物夹杂也能完全切断 When using rubber diaphragm, even if there are some foreign matters in the fluid, it can be completely cut off
3.清洗性优异 Excellent cleaning performance
流体通路部采用流线型，不存在阀套部，因此可将积液降至最低，保持自净性 The fluid passage is streamlined and there is no valve sleeve, so the accumulation of liquid can be minimized and self purification can be maintained
4..保养性优异 Excellent maintenance
采用“驱动部”、“隔膜”、“阀体”的三单元方式，拆解和装配方便 The three unit mode of "drive part", "diaphragm" and "valve body" is adopted, which makes disassembly and assembly convenient
采用顶部入口结构，因此无需将阀从管道上拆下，只要将阀体和阀盖的紧固螺栓和螺母卸下即可更换隔膜 The top inlet structure is adopted, so it is unnecessary to remove the valve from the pipeline. The diaphragm can be replaced by removing the fastening bolts and nuts of the valve body and bonnet
各单元具有兼容性，手动阀也能方便地改为自动化等方式 Each unit has compatibility, and manual valves can be easily changed to automation
