衛(wèi)生級隔膜閥 Diaphragm Valves
應(yīng)用 隔膜閥手動或氣動操作，專門應(yīng)用于制藥工業(yè)中的衛(wèi)生和無菌過程。
該閥門非常適用于流體控制和開/關(guān)的任務(wù)。
工作原理 膜片提供閥體密封和閥座密封。里面沒有路徑通到外部環(huán)境，所以該閥門適用于無菌過程。
當(dāng)閥門關(guān)閉時，支撐膜片的壓力墊朝閥體上的密封面移動。當(dāng)壓力板移動時,膜片彎曲，被迫推向閥體中心的閥座區(qū)域，因此關(guān)閉了通向閥體的流體路徑。
閥體和壓力板的相互關(guān)系，防止了膜片的擠壓。
該閥門可以手動也可以氣動操作，也可以通過控制器和電磁閥控制。

Diaphragm Valves
Applications
Diaphragmvalves，manually or pneumatic ally operated，are specifically designed for use on hygienic and aseptic processesin the pharmaceutical industries. The valve is excellent for flow control aswell as for open/close duties.
Operating PrinciplesThe diaphragm provides the body seal as well as the seat seal. There are nopaths to the outside environment and as such the valve is suitable for aseptic processes.
Asthe valve is closed a pressure pad which supports the diaphragm moves towardsthe sealing face on the body. As the pressure plate moves the diaphragm flexes andis forced down onto the seat area in the centre of the body thus closing offthe flow path through the body. The inter-relationship of body to the pressureplate prevents over compression of the diaphragm. The valve can be actuatedeither manually or pneumatically and controlled by control tops and solenoidvalves.
Technical specifications Max.pressure: 10 BAR(145PSl)
Workingtemperature:-10℃ to +120℃(EPDM)- 14°F to 248°F(+ 140℃(SIP,max.30 min) 284°F)
