特點∶ Performance characteristics
1.氣密性優異 Excellent air tightness
驅動部通過隔膜隔離,因此無球閥、蝶閥之類的填料壓蓋部,無外部泄漏或外界空氣進入污染流體 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.閥座零泄漏 Zero leakage of valve seat
可撓性隔膜將流體隔斷,因此閥座無泄漏 The flexible diaphragm blocks the fluid, so the valve seat has no leakage
采用橡膠隔膜時,即使流體內有些異物夾雜也能完全切斷 When using rubber diaphragm, even if there are some foreign matters in the fluid, it can be completely cut off
3.耐蝕性?耐化學性優異 Excellent corrosion resistance and chemical resistance
閥體形狀簡單,適合襯里加工 Simple shape of valve body, suitable for lining processing
通過橡膠、氟樹脂等各種襯里閥體和豐富的隔膜材料相組合,可制造適合各種流 Through the combination of rubber, fluororesin and other lining valve bodies and rich diaphragm materials, it can be manufactured to be suitable for various flows
體規格的閥,性價比優于特殊合金類材料 Body size valve, cost-effective than special alloy materials
4.清洗性優異
流體通路部采用流線型,不存在閥套部,因此可將積液降至最低,保持自凈性
5.保養性優異 Excellent maintenance
采用“驅動部”、“隔膜”、“閥體”的三單元方式,拆解和裝配方便 The three unit mode of "drive part", "diaphragm" and "valve body" is adopted, which makes disassembly and assembly convenient
采用頂部入口結構,因此無需將閥從管道上拆下,只要將閥體和閥蓋的緊固螺栓和螺母卸下即可更換隔膜 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
各單元具有兼容性,手動閥也能方便地改為自動化等方式 Each unit has compatibility, and manual valves can be easily changed to automation
