Izici eziyinhloko okufanele zicatshangelwe lapho uklamaizivalo uvemvaneyilezi:

1. Izimo zenqubo yesistimu yenqubo lapho i-valve ikhona

Ngaphambi kokuklama, kufanele uqale uqonde ngokugcwele izimo zenqubo yohlelo lwenqubo lapho i-valve itholakala khona, okuhlanganisa: uhlobo oluphakathi (igesi, uketshezi, isigaba esiqinile kanye nesigaba sezigaba ezimbili noma ingxube yezigaba eziningi, njll.), izinga lokushisa eliphakathi nendawo, eliphakathi nendawo. ukucindezela, ukugeleza okuphakathi (noma izinga lokugeleza), umthombo wamandla kanye nemingcele yawo, njll.

1) Uhlobo lwemidiya

Iuvemvane valveukwakheka kuvame ukuklanywa ngokwendlela eyinhloko, kodwa imidiya eyisizayo, njengaleyo esetshenziselwa ukuhlanza, ukuhlola nokuhlanza, nayo kufanele icatshangelwe. Ukunamathela kanye nokubekwa kwe-medium kunomthelela ekwakhiweni kwe-valve; ngesikhathi esifanayo, ukunakwa okwengeziwe kufanele kukhokhwe emthelela wokugqwala kwe-medium esakhiweni nasezintweni.

2) Izinga lokushisa eliphakathi

Izinkinga ezingaba khona zihlanganisa: ① Ukunwetshwa okushisayo okuhlukile: I-gradient ehlukile yezinga lokushisa noma ama-coefficients okunweba azobangela ukwanda okungalingani kwepheya yokuvala ama-valve, okubangele ukuthi i-valve ibhajwe noma ivuze lapho ivula noma ivala. ② Izinguquko ezimpahleni ezibonakalayo: Ukuncipha kokucindezelwa okuvumelekile kwezinto emazingeni okushisa aphezulu kufanele kucatshangelwe ngesikhathi sokuklama. Ukwengeza, ukuhamba ngebhayisikili okushisayo kwesinye isikhathi kungabangela izinguquko zobukhulu njengoba izingxenye ezikhula emazingeni okushisa aphakeme kakhulu zingathela endaweni. ③Ingcindezi yokushisa kanye nokushaqeka okushisayo.

3) Ukucindezela okuphakathi

Ithinta kakhulu amandla nokuqina komklamo wezingxenye ezithwala ingcindezi yeuvemvane valve, kanye nomklamo wengcindezi ethile edingekayo kanye nokucindezela okuqondile okuvunyelwe kokupheya kokuvala.

4) Ukugeleza okuphakathi

Ithinta kakhulu ukumelana nokuguguleka kwesiteshi se-butterfly valve kanye nokuvala uphawu, ikakhulukazi i-gas-solid kanye ne-liquid-solid yezigaba ezimbili zokugeleza kwemidiya, okumele kucatshangelwe ngokucophelela.

5) Ukunikezwa kwamandla

Imingcele yayo ithinta ngokuqondile umklamo wokuxhumana wokuxhumana, isikhathi sokuvula nokuvala, ukuzwela kwedrayivu nokuthembeka kwe-valve butterfly. Izinguquko ku-voltage yokuphakelwa kwamandla kanye namandla amanje anomthelela omncane ku-valve. Ngokuyinhloko, ukucindezela nokugeleza komthombo womoya kanye nomthombo we-hydraulic kuzothinta ngokuqondile ukugcwaliseka komsebenzi we-butterfly valve.

2. Umsebenzi we-valve we-Butterfly

Lapho uklama, kufanele kucace ukuthi i-valve uvemvane isetshenziselwa ukuxhuma noma ukusika i-medium epayipini, noma ukulawula nokulawula ukugeleza nokucindezela kwe-medium epayipini. Izici ezicatshangelwe ekwakhiweni kwepheya yokuvala ama-valve okulawula anemisebenzi ehlukene ahlukile. Uma i-valve isetshenziselwa ukuxhuma noma ukusika i-medium epayipini, umthamo wokusika we-valve, okungukuthi, ukusebenza kokuvala kwe-valve, kubalulekile ukuqinisekisa ukuthi okukhethiwe Ngaphansi kwesisekelo sokuthi impahla kufanele igle- ukumelana, okuphansi, ukucindezela okuphakathi kanye nama-valve okushisa ajwayelekile ngokuvamile athatha isakhiwo sokuvala uphawu oluthambile, kuyilapho ama-valve alawulayo aphakathi, asezingeni eliphezulu kanye naphezulu asebenzisa isakhiwo sokuvala kanzima; uma i-valve isetshenziselwa ukulawula nokulawula okuphakathi epayipini Uma kucutshungulwa izinga lokugeleza nokucindezela, izici zokulawula ezingokwemvelo kanye nesilinganiso sokulawula se-valve kubhekwa ngokuyinhloko.
