Umhlahlandlela oyisisekelo wokuvimbela ukwehluleka kwe-valve yokuhlola

Siyakwamukela ku-Thomas Insights-nsuku zonke, sizokhipha izindaba zakamuva nokuhlaziya ukuze sigcine abafundi bethu benolwazi lwakamuva ngamathrendi embonini. Bhalisa lapha ukuze uthumele izihloko zezindaba zosuku ngokuqondile ebhokisini lakho lokungenayo. Cishe yonke imboni esebenzisa amapayipi ukuthutha uketshezi incike ekusetshenzisweni kwamavalvu okuhlola. Hlola amavalvu-aphinde abizwe ngokuthi ama-sheke valve, hlola amavalvu, noma hlola amavalvu-vumela ukugeleza endaweni eyodwa kuphela kuyilapho uvimbela ukugeleza kolunye uhlangothi noma okuphambene. Lawa mavalvu avuleka futhi avaleke kuphela ngokusekelwe kumfutho we-hydraulic okhiqizwa ukugeleza kwamanzi okusebenza kumshini we-valve. Amavalvu okuhlola avame ukusetshenziswa emigqeni yesitimu, imigqa ye-condensate, imigqa yamanzi, izinhlelo ze-HVAC, namaphampu okuphakelayo amakhemikhali, ukusho nje izinhlelo ezimbalwa ezivamile. Lawa ma-valve ayizingxenye ezibalulekile ezimweni eziningi, ngoba ukugeleza okubuyela emuva kungabangela umonakalo omkhulu kwezinye izinto zokusebenza. Ngakho-ke, izimpawu zokwehluleka kwe-valve yokuhlola kufanele zibonwe kusenesikhathi ukuze kuvinjelwe isikhathi sokungasebenzi kwesikhungo kanye nokulungiswa okumba eqolo. Ukugqokwa kwama-elastomer nezigxivizo zezihlalo kanye namazinga okushisa aphezulu okusebenza nakho kungabangela ukwehluleka kwamavalvu okuhlola. Isihluthulelo sokuvimbela ukwehluleka kwe-valve yokuhlola kanye nokuqinisekisa impilo yesevisi ye-valve ilungile futhi ijwayele ukugcinwa kokuvimbela. Isinyathelo sokuqala nesisebenzayo sokugwema ukwehluleka kwama-valve ukugcina amapayipi nama-valve ehlanzekile futhi engenawo udoti. Lokhu kungafezwa ngokufaka izihlungi namakhava lapho kudingeka khona. Isistimu yokukhipha amapayipi ingase igezwe njalo ukuze kukhishwe udoti oboshiwe futhi kuncishiswe ukunqwabelana kokungcola. Ukugcotshwa kwe-valve kungenye indlela ephumelelayo yokuvimbela ukwehluleka kwe-valve ngaphambi kwesikhathi. I-valve yokuhlola yakhiwe izingxenye eziningana ezihambayo; ngakho-ke, ukunciphisa ukungqubuzana phakathi kwalezi zingxenye ngokusebenzisa ukugcoba kungandisa impilo yesevisi yezingxenye ze-valve, kuthuthukise ukusebenza okuphelele, nokuqinisekisa ukusebenza kahle. Ekugcineni, i-valve kufanele ifakwe ngendlela efanele futhi isetshenziswe njengoba kuqondiswe. Ukufakwa okungalungile kwe-valve noma ukusebenzisa uhlobo olungalungile lwe-valve yokuhlola kuzonciphisa impilo yesevisi ye-valve. Uhlelo olujwayelekile lokulungisa kufanele futhi lwenziwe ukuze kuqinisekiswe ukuthi ama-valve anephutha ayashintshwa lapho kuvela izimpawu zokuqala zokwehluleka. Uma ukhetha usayizi we-valve, khumbula ukuhlola i-valve yokuhlola yesicelo esinikeziwe, hhayi ubukhulu bepayipi. Ukucabangela izidingo zamandla zesikhathi esizayo, ukwandisa ubukhulu bepayipi kuwumkhuba ovamile. Kodwa-ke, ububanzi bepayipi elikhulu buzoveza izinga lokugeleza eliphansi, okusho ukuthi kungase kungabi khona isivinini samanzi esanele sokuvula ngokugcwele i-valve yokuhlola. Lokhu kubangela ukuthi i-valve ejikelezayo, enosayizi ngokobubanzi bepayipi, ijike iye emuva naphambili phakathi kwezindawo ezivuleke kancane nezivaliwe. Lesi simo sibizwa ngokuthi ukuxoxa. Ukuvama kokunyakaza okubangelwa ukudlidliza kuzogcina kukhuphule izinga lokuguga kwama-valve futhi kubangele ukwehluleka kwengxenye, okuzolimaza kakhulu ezinye izinto zokusebenza ezansi nomfula. Ngakho-ke, i-valve yokuhlola kufanele ikhethwe ngokwezinga lokugeleza elilindelekile. Lokhu kuhilela ukukhetha ivalvu enenani elifanele le-valve (CV). Inani le-CV lichaza ikhono le-medium egelezayo yokuvula ngokugcwele i-valve; uma i-CV iphakeme, kukhulu ukugeleza okudingekayo ukuze uvule i-valve. Kufanele futhi ucabangele uhlobo lwe-medium ezodlula ku-valve. Isibonelo, imidiya ebolayo noma elimazayo ingase idinge ukusetshenziswa kwezinto ezithile zamavalvu, njenge-carbon steel, insimbi engagqwali, noma ithusi. Ngaphezu kwalokho, kuyadingeka ukucabangela izici zoketshezi oludlula epayipini ukuze kuqinisekiswe ukugeleza okungaphazanyiswa. Okuqinile, okuwuketshezi, namagesi konke kuhlukile nge-viscosity, ukuminyana, kanye nekhwalithi. Umshini we-valve wangaphakathi kufanele uvumele le midiya eyingqayizivele ukuba ifakwe. Ukuma kwe-valve nakho kubalulekile ukunquma uhlobo olulungile lwe-valve yokuhlola yohlelo olunikeziwe. Uma efakwe ngaphansi kwezimo zokugeleza okuqondile, amanye ama-valve angase angasebenzi njengoba kulindelekile. Ukwengeza, uma i-valve ithathwa njengefanele ukugeleza okuqondile, isiqondiso (phezulu noma phansi) kufanele sinqunywe ngoba lezi zimo zinezidingo eziyingqayizivele. Nakuba wonke ama-valve okuhlola enza umsebenzi ofanayo, izindlela zawo zangaphakathi zivumela ukugeleza kwendlela eyodwa ngezindlela ezihlukene. Ngayinye yalezi zindlela ifanele izimo ezahlukene; ngakho-ke, kuyadingeka ukuqonda izindlela eziyisisekelo zokusebenza zalawa ma-valve ukuze unqume ukuthi yisiphi isicelo esifaneleka kakhulu. Izinhlobo ezahlukene zama-valve okuhlola—nakuba zifana ngokomqondo—zihluke kakhulu ngokwendlela ye-valve yangaphakathi, ukucindezela kokuqhekeka (okuhlobene ne-CV), nezinto zokwakha. Imishini yangaphakathi yala ma-valve nayo iyazwela emfucumfucwini, amazinga okugeleza kanye neziqongo zokucindezela. Ngakho-ke, ukukhethwa okufanele kwama-valve kanye nokuhlolwa okufanele kwesimiso kuyisihluthulelo sokuvimbela ukwehluleka ngaphambi kwesikhathi kwama-valve okuhlola kunoma yiluphi uhlobo lwesicelo.
