I-Common Valve Knowledge I

一 Ivalve yovemvane I-disc ye-butterfly valve iyidiski, ezungeza i-eksisi esihlalweni. I-engeli yokujikeleza yizinga lokuvula nokuvala le-valve. Izinzuzo zayo ziyi-lightweight, isakhiwo esilula, ukonga impahla uma kuqhathaniswa namanye ama-valve, ukuvula nokuvala okusheshayo, ukusika nokudonsa kungasetshenziswa, ukumelana noketshezi kuncane, ukusebenza kusindisa abasebenzi, kungenziwa ibe yizinga elikhulu. Ama-valve ovemvane asetshenziswa kakhulu kumapayipi amanzi ashisayo. Lapho i-butterfly valve ingasetshenziswa khona, kungcono ukungasebenzisi ama-valve esango, ngoba ama-butterfly valves ayonga kakhulu kunama-valve esango futhi anesimiso esihle.二 I-valve ye-diaphragm I-valve ye-diaphragm isetshenziselwa ukuhlukanisa indawo yomoya ngokucindezela ifilimu ye-elastomer ngokuqinile esihlalweni ngesiqu se-valve. Ukuzungezisa isondo lesandla kungashayela isiqu phezulu naphansi, ukuze i-diaphragm ishiye isihlalo ukuze ivule i-valve noma yenze i-diaphragm icindezele ngokuqinile esihlalweni ukuze ivale i-valve. Izikhathi zokusetshenziswa kwawo amanzi acwenge kakhulu, amanzi ahlanzekile kakhulu awadingi i-engeli efile epayipini lokugeleza; okwesibili, kukhona ukungcola kwendle, isisombululo, njll., i-particle ball valve oketshezini kulula ukuyigqoka futhi idabuke futhi ivuze, ukuvalwa okuphezulu nangaphansi kwe-valve ye-diaphragm kugwema kakhulu le nkinga, futhi i-diaphragm ingashintshwa ngemva kwesikhathi eside- ukusetshenziswa kwesikhathi.三 I-engeli valve Umzimba we-angular valve une-engeli yesokudla, umzimba we-valve unesihlalo nendawo evalekayo, ngokuvamile ephansi ngaphakathi nangaphandle. Imodeli yokusetshenziswa inezinzuzo zesakhiwo esilula kanye nomphumela omuhle wokuvala uphawu. Ngomsebenzi wokuzihlanza, umzimba we-valve akulula ukuqoqa ukungcola, awufanele ukuxhuma, ulungele ukulawula imidiya ye-viscosity ephezulu, umehluko wengcindezi ephezulu kanye nemidiya equkethe indaba emisiwe kanye ne-particle. Ububi ukuthi ijwayele ukuguquguquka kwe-valve engazinzile.四 I-Valve Yokulawula Ifilimu Yomoya I-actuator yevalvu yokulawula ifilimu yomoya inemiphumela emihle nemibi. Umphumela omuhle uwukuthi lapho umfutho ukhuphuka, isiqu se-valve siya phansi, futhi ingcindezi ingena ekamelweni lefilimu ngaphezu kwe-diaphragm eboshiwe. Ukusabela kusho ukuthi lapho umfutho ukhuphuka, isiqu se-valve siya phezulu, futhi ukucindezela kuyigumbi lefilimu elingaphansi kwe-diaphragm ewuthayela.
