Iivalve zesango zizinto ezibalulekileyo ezilawula ukuhamba kwamanzi kwiinkqubo ezahlukeneyo, kwaye ukuqonda umahluko phakathi kweentlobo ezahlukeneyo zeevalve zesango kubalulekile ekukhetheni i-valve yesango echanekileyo kwisicelo esithile. Kule blog, thina'Iza kuntywila kumahluko phakathi kwe-NRS (isiqu esihlaziyiweyo) kunye ne-OS&Y (intambo yangaphandle kunye nedyokhwe) iivalvu zesango, zicacisa iimpawu zazo ezizodwa kunye nokusetyenziswa.
Iivalvu zesango le-NRS ziyilwe ngesiqu esifileyo, okuthetha ukuba isikhondo asihambi sinyuka okanye sisezantsi xa kusetyenziswa ivalve. Ezi zivalo zisoloko zisetyenziselwa ukulawula ukuhamba kwamanzi kwiinkqubo zokutshiza apho imiqobo yendawo okanye ufakelo oluphantsi komhlaba lwenza ukusetyenziswa kweevalvu zesango ezineziqu ezinyukayo zingasebenzi. Iivalvu zesango le-NRS ziyafumaneka nge-2″ yokusebenza nut okanye ivili lesandla ozikhethelayo, libonelela ngokuguquguquka kokukhethwa kwabathengi.
Iivalvu zesango le-OS&Y, kwelinye icala, zibandakanya isikrufu sangaphandle kunye noyilo lwedyokhwe kunye nesiqu esibonakala ngaphandle kwevalve kwaye siqhutywa yidyokhwe. Olu hlobo lwevalve yesango luhlala luxhotyiswe nge-wedge eyomeleleyo kunye ne-pre-grooved stem yokufaka i-switch monitoring. Uyilo lwe-OS & Y luvumela ukuhlolwa okubonakalayo okulula kokusebenza kwevalvu kunye nokulula ukongeza izincedisi ngenjongo yokubeka iliso kunye nokulawula.
Iimpawu eziqaphelekayo:
Umahluko ophambili phakathi kwe-NRS kunye ne-OS&Y iivalvu zesango kuyilo lwesiqu kunye nokubonakala. Izivalo zesango le-NRS zinezikhondo ezifihliweyo zokusetyenziswa apho isithuba sinqongopheleyo okanye isivalo sifakwe ngaphantsi komhlaba. Ngokwahlukileyo, iivalve zesango le-OS & Y zinesiqu esibonakalayo esinyuka sinyuka xa i-valve isebenza, ivumela ukubeka iliso lula kunye nokongeza i-switch monitoring.
Isicelo:
Iivalvu zesango le-NRSzisetyenziswa ngokuqhelekileyo kwiinkqubo zokuhambisa amanzi aphantsi komhlaba, iinkqubo zokukhusela umlilo kunye neenkqubo zokunkcenkceshela apho kufuneka ukulawula ukusebenza kwevalve ngaphandle kwesidingo sokuhlolwa okubonakalayo rhoqo. Ngakolunye uhlangothi, iivalve zesango ze-OS & Y, zikhethwa kwizicelo ezifuna ukubeka iliso kunye nokugcinwa rhoqo, njengeenkqubo zoshishino, iinkqubo ze-HVAC, kunye nezityalo zokunyanga amanzi.
Khetha ivalve elungileyo:
Xa ukhetha phakathi kwe-NRS kunye ne-OS & Y iivalve zesango, kubalulekile ukuqwalasela iimfuno ezithile zesicelo. Imiba efana nemiqobo yendawo, ukugcinwa lula, kunye neemfuno zokubeka iliso ezibonakalayo ziya kumisela uhlobo lwevalve yesango elulungele kakhulu usetyenziso olucetywayo.
Isishwankathelo, ukuqonda umahluko phakathi kwe-NRS kunye ne-OS & Y iivalve zesango kubalulekile ukwenza isigqibo esinolwazi xa ukhetha i-valve echanekileyo kwisicelo esithile. Ngokuqwalasela imisebenzi ekhethekileyo kunye nokusetyenziswa kohlobo ngalunye, iinjineli kunye nabaqulunqi benkqubo banokuqinisekisa ukuba iivalve zesango zifezekisa ukusebenza kakuhle kunye nokusebenza kwiinkqubo zabo.
