Ho na le lintlha tse qaqileng hore bo-ralitima-mollo ba kene bohareng ba mollo 'me ka letsoho ba fetola 8,000 ho koala valve.Batho ba sa tsebeng lintlha tse qaqileng ba ka 'na ba re "sena se feteletse haholo."Ha e le hantle, ralitima-mollo o ile a bululela pale "E sebete ka ho fetisisa" paleng "e ile ea fetola valve 80,000 lihora tse 6 pele e e koala.
U se ke ua tšosoa ke palo eo, filiming ke "gate valve", empa kajeno re bua ka valve ea butterfly.Palo ea liphetohelo tse hlokahalang ho koala valve ea serurubele ea DN e tšoanang ha ho hlokahale hore e be ngata hakaalo.
Ka bokhutšoanyane, palo ea ho bula le ho koala nako le nako ea ts'ebetso ea valve ea serurubele e itšetlehile ka lintlha tse ngata, tse kang mofuta oa actuator, sekhahla sa phallo e bohareng le khatello, joalo-joalo, 'me e hloka ho khethoa le ho lokisoa ho ea ka boemo ba sebele. .
Pele re buisana ka palo ea ho chenchana ho hlokahalang ho koala valve ea serurubele, a re utloisiseng pele sesebelisoa se hlokahalang ho bula valve ea serurubele: actuator.Li-actuator tse fapaneng li na le lipalo tse fapaneng tsa ho chenchana tse sebelisetsoang ho koala valve ea serurubele, 'me nako e hlokahalang le eona e fapane.
Nako ea ho bala nako ea ho bula le ho koala ea serurubele Nako ea ho bula le ho koala ha belofo ea serurubele e bolela nako e nkang hore belofo ea serurubele e qetelle ho tloha e bulehile ka ho feletseng ho isa ho e koetsoeng ka ho feletseng kapa ho tloha e koetsoe ka ho feletseng ho ea ho bula ka ho feletseng.Nako ea ho bula le ho koala ha valve ea serurubele e amana le lebelo la ketso la actuator, khatello ea mokelikeli le lintlha tse ling.

Har'a tsona, t ke nako ea ho bula le ea ho koala, 90 ke lebelo la ho potoloha ha valve ea serurubele, 'me ω ke lebelo la angular la valve ea serurubele.
1. Tšoara valve ea serurubele e sebetsang:
Ka kakaretso e hlomelloa ka li-valve tsa serurubele tse nang le DN ≤ 200 (boholo bo boholo bo ka ba DN 300).Mothating ona, re tlameha ho bua ka mohopolo o bitsoang "torque".
Torque e bolela boholo ba matla a hlokahalang ho bula kapa ho koala valve.Torque ena e angoa ke lintlha tse fapaneng, ho kenyelletsa le boholo ba valve ea serurubele, khatello le litšobotsi tsa mecha ea litaba, le likhohlano ka har'a kopano ea valve.Litekanyetso tsa torque hangata li hlahisoa ka Newton metres (Nm).
