Izici eziyinhloko okufanele zicatshangelwe lapho kuklanywaamavalvu ebhabhathaneziyi:

1. Izimo zenqubo yesistimu yenqubo lapho i-valve itholakala khona

Ngaphambi kokuklama, kufanele uqale uqonde ngokugcwele izimo zenqubo yesistimu yenqubo lapho i-valve itholakala khona, okuhlanganisa: uhlobo oluphakathi (igesi, uketshezi, isigaba esiqinile kanye nengxube yezigaba ezimbili noma eziningi, njll.), izinga lokushisa eliphakathi, ingcindezi ephakathi, ukugeleza okuphakathi (noma izinga lokugeleza), umthombo wamandla kanye nemingcele yawo, njll.

1) Uhlobo lwemidiya

Iivalvu yebhabhathaneIsakhiwo sivame ukwakhiwa ngokwendlela eyinhloko, kodwa imidiya yokusiza, njengaleyo esetshenziselwa ukuhlanza, ukuhlola nokuhlanza, nayo kumele icatshangelwe. Ukunamathela kanye nokufakwa kwendlela kunomthelela ekwakhiweni kwesakhiwo se-valve; ngesikhathi esifanayo, kufanele kuqashelwe kakhulu umthelela wokugqwala kwendlela esakhiweni nasezintweni.

2) Izinga lokushisa eliphakathi

Izinkinga ezingaba khona zifaka: ① Ukwanda okuhlukile kokushisa: Ama-gradient ahlukene okushisa noma ama-coefficient okunweba azobangela ukwanda okungalingani kwepheya lokuvala i-valve, okubangela ukuthi i-valve ibambeke noma ivuze lapho ivula futhi ivala. ② Izinguquko ezimpahleni zezinto: Ukunciphisa ukucindezeleka okuvumelekile kwezinto ezisezingeni lokushisa eliphezulu kumele kucatshangelwe ngesikhathi sokuklama. Ngaphezu kwalokho, ukujikeleza kokushisa ngezinye izikhathi kungabangela izinguquko zobukhulu njengoba izingxenye ezikhula emazingeni okushisa aphezulu kakhulu zingase ziveze endaweni. ③Ukucindezeleka kokushisa kanye nokushaqeka kokushisa.

3) Ingcindezi ephakathi nendawo

Kuthinta kakhulu ukwakheka kwamandla nokuqina kwezingxenye ezithwala ingcindezi ze-ivalvu yebhabhathane, kanye nomklamo wokucindezela okudingekile kanye nokucindezela okuvumelekile kwepheya lokuvala.

4) Ukugeleza okuphakathi

Kuthinta kakhulu ukumelana nokuguguleka kwesiteshi se-butterfly valve kanye nendawo yokuvala, ikakhulukazi kwezokuxhumana zokugeleza kwezigaba ezimbili zegesi eqinile kanye ne-liquid-solid, okumele kucatshangelwe ngokucophelela.

5) Ukunikezwa kwamandla

Amapharamitha ayo athinta ngqo ukwakheka kwesixhumi soxhumano, isikhathi sokuvula nokuvala, ukuzwela kokushayela kanye nokuthembeka kwevalvu yevemvane. Izinguquko kumandla kagesi kanye nokuqina kwamanje azinawo umphumela omkhulu kuvalvu. Ngokuyinhloko, ingcindezi kanye nokugeleza komthombo womoya kanye nomthombo we-hydraulic kuzothinta ngqo ukufezeka komsebenzi wevalvu yevemvane.

2. Umsebenzi we-valve ye-Butterfly

Uma uklama, kumele kucace ukuthi ivalvu yebhabhathane isetshenziselwa ukuxhuma noma ukusika i-medium epayipini, noma ukulawula nokulawula ukugeleza kanye nengcindezi ye-medium epayipini. Izici ezicatshangelwayo ekwakhiweni kwe-sealing pair yamavalvu okulawula anemisebenzi ehlukene zihlukile. Uma ivalvu isetshenziselwa ukuxhuma noma ukusika i-medium epayipini, amandla okusika evalvu, okungukuthi, ukusebenza kokuvala kwevalvu, kubalulekile ukuqinisekisa ukuthi okukhethiwe Ngaphansi kwesisekelo sokuthi izinto kumele zingagqwali, zicindezeleke kancane, ziphakathi futhi zisezingeni lokushisa elijwayelekile zivame ukusebenzisa isakhiwo sokuvala esithambile, kuyilapho amavalvu okulawula aphakathi, aphezulu kanye naphezulu esebenzisa isakhiwo sokuvala esiqinile; uma ivalvu isetshenziselwa ukulawula nokulawula i-medium epayipini Uma kucatshangelwa izinga lokugeleza kanye nengcindezi, izici zokulawula ezingokwemvelo kanye nesilinganiso sokulawula sevalvu kucatshangelwa kakhulu.
