Ihlakaniphile～Ingavuzi～Ihlala isikhathi eside–Ivalvu yesango legezi ukuthola isipiliyoni esitjha sokulawula ihlelo lamanzi elisebenza kuhle

Eensetjenzisweni ezifana nokuphakelwa kwamanzi nokukhipha amanzi, amahlelo wamanzi womphakathi, amanzi ajikelezako webubulo, nokuthelelela kwezokulima, amavalvu asebenza njengeengcenye eziqakathekileko zokulawula ukugeleza. Ukusebenza kwazo kunquma ngqo ukusebenza kuhle, ukuzinza, nokuphepha kwehlelo loke. Iklanyelwe khulukhulu ukusetjenziswa kwamanzi, ivalvu yegezi ihlathulula kabutjha amazinga wamavalvu wesistimu yamanzi ngeenzuzo zayo eziqakathekileko: ukutjhayela okuhlakaniphileko, ukuvala okuqinileko kwamabhamuza, nokuhlala isikhathi eside. Inikela ngesisombululo esithembekileko seenkhathi ezinengi zokulawula ukugeleza.

Akusekho ukugandeleleka ngezandla. Yamukela idrayivu kagesi ehlakaniphileko.

Kwendabukoamavalvu wesango wesandlaithembele ekusebenzeni ngezandla, okungasi budisi ukusebenza kwaphela eendaweni ezifana nokuphakama, imithombo etjhingako, kanye nezikhala ezincani, kodwana kuvame ukulimala kwevalvu nokuvala okumbi ngebanga lamandla wezandla angalinganiko. Amavalvu wesango kagesi afakwe iinjini ezisebenza kuhle khulu, ezihlanganiswe namasistimu wokulawula we-elekthronikhi:

1. Isekela kokubili ukulawula okukude/kwendawo, okuvumela ukusebenza okuzenzakalelayo nge-PLC, ama-frequency converters, nofana amakhabethe wokulawula ahlakaniphileko, ngaphandle kwesidingo sabasebenzi abasendaweni, ukwehlisa khulu iindleko zabasebenzi;
2. Ivalvuvula/valaine-stroke eqondileko nelawulekako, enephutha ≤0.5mm, ukufikelela lula ukulungiswa okuhle kokugeleza nokuvala okuqondileko, ukubalekela ukutjhuguluka kokugeleza kwamanzi okubangelwa ziiphoso zokusebenza;
3. Ngokuvikela umthwalo omkhulu kanye namaswitjhi womkhawulo, ivalvu iyama ngokuzenzakalelayo nangabe ihlangana nesithiyo nofana ifinyelele endaweni yayo yokugcina, ukukhandela ukutjhiswa kwemoto nokulimala kwemitjhini ukunweba ipilo yokusebenza.

Ukuqinisekisa ukuvala okuqinileko, okungavuzi ukuvikela imithombo yethu yamanzi eyigugu.

Ukuvuza erherhweni lamanzi akugcini ngokuchitha imithombo yamanzi kodwana kungabanga neengozi zokuphepha ezifana nokugqwala kwemitjhini kanye namaphasi atjhelelako. Ivalvu yesango kagesi yenze ngcono khulu esakhiweni sayo sokuvala:

1. Isihlalo sevalvu senziwe ngezinga lokudlaNBRnofana i-EPDM, ejamelana nokugqwala kwamanzi nokuguga. Ifanela umgogodla wevalvu ngokunemba okungu-99.9%, ifinyelela ukuvala okungekho ukuvuza begodu ihlangabezana neemfuneko zekhwalithi yamanzi ephezulu yamanzi wokusela namanzi ahlanjululwe emabubulweni;
2. Umgogodla wevalvu wenziwe ngensimbi engagqwali eyi-304 kusetjenziswa ikambiso yokubumba ehlanganisiweko, lapho ingaphezulu lipholitjhiwe libe budisi obungu-Ra≤0.8μm, ukwehlisa ukuguga okuvela ekugelezeni kwamanzi begodu kuvimbele ukuhluleka kokuvala okubangelwa kukwakheka kwesikali;
3. I-valve stem yamukela umklamo we-double-seal, ngokupakisha kwe-graphite okuguquguqukako kanye ne-O-ring seal eyakhelwe ngaphakathi kwegumbi lokupakisha, okungagcini ngokuvimbela ukuvuza kwamanzi esiqwini se-valve kodwana kwehlisa nokujamelana nokutjhayisana ngesikhathi sokunyakaza kwesiqu se-valve, okuqinisekisa ukusebenza okubushelelezi kwesikhathi eside.

Isakhiwo esinamandla esiphezulu esenzelwe ubujamo obuyinkimbinkimbi be-hydraulic.

Ubujamo bokusebenza kwamahlelo wamanzi ahlukahlukeneko buyahluka khulu, njengendawo enomfutho omkhulu wokuphakelwa kwamanzi ezakhiweni eziphakemeko, ikhwalithi yamanzi ebolako ekujikelezeni kwezebubulo, kanye nodaka nokusilaphazeka ekutheleleleni kwezokulima, koke lokhu kubeka iimfuno eziphezulu emandleni wesakhiwo samavalvu. Ivalvu yesango kagesi yenzelwe ngokukhethekileko ukuqinisa ukusebenza kwamanzi:

1. Umzimba wevalvu wenziwe nge-grey cast iron HT200 nofana i-ductile iron QT450, eneukuqinaamandla we-≥25MPa, akghone ukujamelana nomfutho wokusebenza we-1.6MPa-2.5MPa, ofanele amahlelo wamanzi ahlukahlukeneko ukusuka ekugandelelekeni okuphasi ukuya ephakathi-phezulu;
2. Udonga lwangaphakathi lomzila wokugeleza lwenzelwe ukulungiswa kwamanzi ukwehlisa ukujamelana nokugeleza kwamanzi, ukwehlisa ukusetjenziswa kwamandla wesistimu, nokukhandela ukubekwa kwe-sediment ngaphakathi komzimba wevalvu, ngaleyo ndlela kwehlise ubungozi bokuvaleleka;
3. Iphasi lisebenzisaI-cycloaliphaticithekhnoloji yokufafaza nge-elekthrostathikhi ye-resin, enobukhulu bokugqoka obungu-≥80 μm. Ingakghona ukujamelana nokuhlolwa kokugqwala kwesifutho setshwayi ama-awa angaphezu kwe-1000, ngokuphumelelako ukukhandela umzimba wevalvu bona ungarusi ngitjho naseendaweni ezinomswakama nezangaphandle.

 

Inzuzo eqakathekilekoI-TWSkulele ekuzibopheleleni kwabo okupheleleko ekhwalithi. Lokhu kubonakala kiyo yoke imikhiqizo yabo, kusukela eyakhiwe ngokutjheja begodu ivalwe kuhle khuluamavalvu wesango kagesiukuya ekusebenzeni okusezingeni eliphezuluiviyaviyaniivalvukunyeamavalvu wokuhlola. Umkhiqizo ngamunye utjengisa amazinga afanako aqinileko wobuciko.
