Emikhakheni yezimboni nezokwakha, ukukhethwa nokufakwa kwamavalvu kuyizinto ezibalulekile ekuqinisekiseni ukusebenza kahle kwezinhlelo.I-TWSsizohlola izinto okufanele zicatshangelwe lapho kufakwa ama-valve amanzi (njenge-butterfly valve, ama-gate valve, nama-check valve).
Okokuqala, ake siqonde izinhlobo ezahlukene zama-valve.ivalvu yebhabhathaneivame ukusetshenziswa ekulawuleni uketshezi, inikeza izinzuzo ezifana nesakhiwo esilula, isisindo esincane, kanye nokuvulwa okusheshayo. Ivalvu yesango isetshenziswa kakhulu ezinhlelweni ezivuleke ngokuphelele noma ezivaliwe ngokuphelele, ezifanele ukuvalwa koketshezi. Ivalvu yokuhlola isetshenziselwa ukuvimbela ukugeleza emuva nokuqinisekisa ukuphepha kohlelo. Uhlobo ngalunye lwevalvu lunezimo zalo ezithile zokusetshenziswa kanye nezidingo zokufakwa.
Uma ufaka ama-valve, indlela yokufaka iyinto ebalulekile okufanele uyicabangele. Izinhlobo ezahlukene zama-valve zinezidingo ezahlukene mayelana nendlela yokugeleza koketshezi ngesikhathi sokufakwa. Nazi ezinye zezinto ezibalulekile okufanele uzicabangele:
1.Isiqondiso Sokugeleza Koketshezi:Ivalvu ngayinye inendlela yokugeleza eklanywe ngendlela ethile, okumele ilandelwe ngesikhathi sokufakwa. Isibonelo,amavalvu ebhabhathanengokuvamile zifakwa ohlangothini lokugeleza koketshezi ukuqinisekisa ukulawulwa okuphumelelayo kokugeleza koketshezi.Amavalvu esangokufanele futhi ifakwe ngendlela efanayo nokugeleza koketshezi ukuze kugwenywe ukuthinta ukusebenza kokuvala kwevalvu.
2. Uhlobo lwe-Valve:Izinhlobo ezahlukene zamavalvu zinezidingo ezahlukene zokuqondisa ngesikhathi sokufakwa.Hlola ama-valvekumele ifakwe ngokwemiyalelo yomenzi ukuqinisekisa ukuthi ivimbela ngempumelelo ukugeleza kwamanzi emuva. Ukufakwa okungalungile kwe-check valve kungaholela ekungasebenzi kahle kohlelo noma ekulimaleni kwemishini.
3. Umklamo Wesistimu:Lapho kuklanywa uhlelo lwamapayipi, indlela yokufaka amavalvu kufanele ihambisane nendlela yonke yokugeleza kohlelo. Abaklami kudingeka bacabangele indawo yokufaka amavalvu, indlela yokuhambisa amapayipi, kanye nezakhiwo zoketshezi ukuqinisekisa ukusebenza kahle kohlelo.
4. Ukugcinwa Nokulungiswa:Indlela yokufaka amavalvu izothinta nomsebenzi wokulungisa nokulungisa kamuva. Ukufinyeleleka kufanele kucatshangelwe ngesikhathi sokufaka ukuqinisekisa ukuhlolwa nokugcinwa okulula uma kudingeka. Isibonelo, isibambo sokusebenza sevalvu yebhabhathane kufanele sibhekane nendlela elula ukuyisebenzisa nsuku zonke.
5. Izici Zemvelo:Kwezinye izimo, izici zemvelo zingathinta nokuqondiswa kokufakwa kwamavalvu. Isibonelo, ezindaweni ezinokushisa okuphezulu noma ezinomfutho ophezulu, ukuqondiswa kokufakwa kwamavalvu kungathinta ukusebenza kwawo kanye nesikhathi sawo sokuphila. Ngakho-ke, izimo zemvelo kufanele zihlolwe ngokugcwele ngaphambi kokufakwa ukuze kukhethwe ukuqondiswa kokufakwa okufanele.
Ngamafuphi, indlela yokufaka ama-valve amanzi (njenge-amavalvu ebhabhathane, amavalvu esango, futhiama-valve okuhlola) kuyisici esibalulekile esingenakunakwa. Ukufakwa kahle akugcini nje ngokuqinisekisa ukusebenza kahle kwevalvu kodwa futhi kwandisa isikhathi sayo senkonzo futhi kunciphisa izindleko zokulungisa. Ngakho-ke, lapho ufaka amavalvu, kubalulekile ukulandela iziqondiso zomenzi kanye nezindinganiso zemboni ukuqinisekisa ukusebenza okuphephile nokuphumelelayo kohlelo.
