I-valve ye-diaphragm
0102030405
I-Pneumatic Acutator Type Pneumatic Diaphragm Valve
Izici Zemikhiqizo
1) Impilo yomjikelezo ophezulu, ukusebenza okuhle kakhulu kokubeka uphawu.
2) Isisindo esincane kanye nokumelana nokugqwala okuhle kakhulu, okuvela ngenxa yokwakhiwa kwe-thermoplastic eyingqayizivele.
3) Zonke Izinsiza ozikhethela zingangezwa kalula noma zisuswe ensimini.
4) Ukumelana nokugeleza okuncane, umthamo wokugeleza okuphezulu, kanye nendawo yokubeka indawo ingafakwa ukuze kuzuzwe ukulawula ukugeleza.
5)Umshini wokumisa uhambo ovalayo olungisekayo uklanyelwe ukuthuthukisa impilo yesevisi ye-diaphragm nokwenza lula inqubo yokulungisa.
Iyini i-valve ye-pneumatic diaphragm?
Ivalvu ye-pneumatic diaphragm eyisisekelo isingeniso se-pneumatic diaphragm valve. iwuhlobo olukhethekile lwe-valve enqanyuliwe, eyavela ngawo-1920. Izingxenye zayo zokuvula nezokuvala ziwucezu lwezinto ezithambile ezenziwe nge-diaphragm, i-valve yomzimba kanye nembobo ye-valve kanye nezingxenye zokushayela ziyahlukaniswa, ngakho-ke kubizwa ngokuthi i-pneumatic diaphragm valve. I-valve ye-pneumatic diaphragm isici esivelele i-diaphragm eya endaweni engezansi yomzimba kanye ne-bonnet cavity ephezulu. Itholakala ku-diaphragm ngaphezu kwesiqu, i-flap nezinye izingxenye ze-medium kusuka ekugqwaleni, isusa isakhiwo sokupakisha sokuvala, futhi ngeke ikhiqize ukuvuza okuphakathi.
Yiziphi izinzuzo ze-pneumatic diaphragm valve?
I-pneumatic diaphragm valve inezinzuzo ezimbili eziyinhloko:
1) i-valve ayidingi i-stem ehlukile yokupakisha ukupakisha isakhiwo sokubekwa uphawu, i-diaphragm endaweni enqanyuliwe ngesikhathi esifanayo idlala indima ekubekweni uphawu kwesiqu.
I-2) Ukuguquguquka kokuvalwa kwe-diaphragm kunokwethenjelwa, futhi ngisho noketshezi olungcolile lungenza umsebenzi omuhle wokusika.
Ngakho-ke, indlela yokusebenza kanye nesiteshi esiphakathi sihlukaniswe ngokuphelele. I-valve ye-diaphragm ye-pneumatic ayikwazi ukusetshenziswa kuphela embonini yokudla kanye nemboni yezemithi, kodwa futhi kwabanye okunzima ukuthutha abezindaba kanye nemidiya eyingozi.
