1.Ingqinibaezigcinwe ixesha elide ziya kuhlolwa rhoqo. Umphezulu ovelileyo wokulungisa uya kugcinwa ucocekile, ukungcola kuya kususwa, kwaye kugcinwe ngokucocekileyo kwindawo engena umoya neyomileyo ngaphakathi. Ukupakisha okanye ukugcinwa kwangaphandle kuthintelwe ngokungqongqo. Ngalo lonke ixesha gcina ingqiniba yomile kwaye ingenisa umoya, gcina isixhobo sicocekile kwaye sicocekile, kwaye usigcine ngokweendlela ezichanekileyo zokusigcina.

2. Ngexesha lofakelo, i-elbow inokufakwa ngokuthe ngqo kwipayipi ngokwendlela yokudibanisa kwaye ifakwe ngokwendawo yokusetyenziswa. Ngokuqhelekileyo, inokufakwa kuyo nayiphi na indawo yombhobho, kodwa kufuneka kube lula ukusebenza. Qaphela ukuba indlela yokuhamba okuphakathi kwe-elbow yokumisa kufuneka ibe phezulu phantsi kwe-disc ye-valve ye-longitudinal, kwaye i-elbow inokufakwa kuphela ngokuthe tye. Nika ingqalelo kukuqina kwe-elbow ngexesha lofakelo ukukhusela ukuvuza kunye nokuchaphazela ukusebenza okuqhelekileyo kombhobho.

3. Xa i-valve yebhola, i-valve yokumisa kunye ne-valve ye-valve ye-elbow isetyenzisiweyo, zivule kuphela okanye zivaliwe ngokupheleleyo, kwaye azivumelekanga ukuba zilungelelanise ukuhamba, ukwenzela ukuba ugweme ukukhukuliseka kwendawo yokutywina kunye nokugqoka ngokukhawuleza. Kukho isixhobo sokutywina esibuyela umva kwivalve yesango kunye nevalve yokumisa imisonto ephezulu. Ivili lesandla lijijwa kwindawo ephezulu ukuthintela ukuvuza okuphakathi ekupakishweni.
