I-varve valve iyi-valve lapho ilungu lokuvala (isango) lihamba ngokuqondile eceleni kwesiteji sesiteshi. I-valulve valve ingasetshenziselwa ukuvulwa okugcwele nokuvalwa okugcwele epayipini, futhi ayikwazi ukusetshenziselwa ukulungiswa nokuthambisa. I-Gate Valve iyi-valve enezinhlobonhlobo zezicelo. Ngokuvamile, kusetshenziselwa ukunciphisa amadivaysi nge-DN ≥ 50mm, futhi kwesinye isikhathi ama-valves wesango nawo asetshenziselwa ukusika amadivaysi ngamadayimitha amancane.
Ukuvulwa nokuvalwa kwengxenye ye-valuya i-vate, futhi ukuqondiswa kwesango kwesango kuyahlukahluka kuye ngasekuqondisweni koketshezi. I-valulve valve ingavulwa ngokuphelele ngokuphelele futhi ivalwe ngokugcwele, futhi ayikwazi ukulungiswa noma iphonswe. Isango linezindawo ezimbili zokubopha uphawu. Lezi zindawo ezimbili zokubopha uphawu zephethini esetshenziswa kakhulu yesango le-valve yakha ukwakheka kwe-wedge. I-wedge angle iyahlukahluka ngamapharamitha we-valve, imvamisa engama-50, no-2 ° 52 'lapho izinga lokushisa eliphakathi liphezulu. Isango le-Wedge Gate Valve lingenziwa linye, elibizwa ngokuthi isango eliqinile; Kungenziwa futhi esangweni elingakhiqiza inani elincane lokukhubazeka ukuze kuthuthukiswe ukwakhiwa kwalo futhi kunxephezele ukuphambuka kwe-angle engaphezulu yokubekwa uphawu ngesikhathi sokulungiswa. Ipuleti libizwa ngesango eliphakeme. I-Gate Valve iyimishini yokulawula ephambili yokugeleza noma ukudlulisela ivolumu yempuphu, izinto zokusanhlamvu, impahla ye-granular nengcezu encane yezinto ezibonakalayo. Kusetshenziswa kabanzi ku-metallurgy, izimayini, izinto zokwakha, okusanhlamvu, imboni yamakhemikhali kanye neminye imboni ukulawula ukuguqulwa kokugeleza noma ukusika ngokushesha.
Ama-galves amasango abhekisela ngqo ezinhlotsheni zama-valves wesango lensimbi, elingahlukaniswa ngamava ama-wedge Gate valves, ama-valves wesango elihambisanayo, kanye ne-wedge Gate valve ngokuya ngokucushwa komhlaba. I-Gate Valve ingahlukaniswa ibe: Uhlobo lwesango olulodwa, uhlobo oluphindwe kabili lwesango nohlobo lwesango le-elastic; I-Parallel Gate Valve ingahlukaniswa ngohlobo lwesango olulodwa nohlobo lwesango eliphindwe kabili. Ngokusho kwesikhundla sentambo yesiqu se-valve, kungahlukaniswa ngezinhlobo ezimbili: ukukhuphuka kwesango lesango kanye ne-vatve yesango elingakhuphukayo.
Lapho i-hatve valve ivaliwe, ingaphezulu lokubekwa uphawu lingavalwa kuphela ngengcindezi ephakathi nendawo, okungukuthi, ukuthembela engcindezi ephakathi nendawo ukucindezela indawo ebeka uphawu lwepuleti yesango ngakolunye uhlangothi ukuze kuqinisekiswe ukubekwa uphawu kobuso bendawo, okukufaka uphawu. Iningi le-Valve Valve liphoqelekile, lokho ukusho, lapho i-valve ivaliwe, isango kufanele licindezelwe esihlalweni se-valve ngamandla angaphandle, ukuze siqinisekise ukubekwa uphawu komhlaba okwenziwe uphawu.
Isango le-GAGV Valve lihamba ngendlela eqondile nesiqu se-valve, esibizwa ngokuthi i-valve ye-stuming stem (ebizwa nangokuthi i-valve yesango elingaphezulu). Imvamisa kunentambo ye-trapezoidal ku-livetter, futhi nge-nati phezulu kwe-valve kanye ne-groove yomhlahlandlela, ukujikeleza okujikelezayo kuguqulwe kube yindlela eqondile yomugqa, okusho ukuthi, i-torque yokusebenza iguqulwe ibe yi-Operation.
Lapho kuvulwa i-valve, lapho ukuphakama kokuphakamisa kwepuleti yesango kulingana no-1: 1 amahlandla abubanzi be-valve, ukudlula koketshezi kuvinjelwe ngokuphelele, kepha lesi sikhundla asikwazi ukubhekwa ngesikhathi sokusebenza. Ekusetshenzisweni kwangempela, i-apex yesiqubulo se-valve isetshenziswa njengesibonakaliso, okungukuthi, isikhundla lapho isiqu se-valve singahambi sithathwe njengesikhundla saso esivulekile ngokuphelele. Ukuze ucabangele into yokukhiya ngenxa yezinguquko zokushisa, imvamisa uvulekele esimweni esiphezulu, bese ubuyisela emuva ijika eli-1 / 2-1, njengesikhundla se-valve esivulekile ngokuphelele. Ngakho-ke, isikhundla esivulekile ngokuphelele se-valve sinqunywa ngesikhundla sesango (okungukuthi, unhlangothi).
Kwamanye ama-valves, i-stem nati isethwe epuletini yesango, futhi ukujikeleza kwesondo lesandla kudonsa isiga se-valve ukujikeleza, nepuleti yesango liphakeme. Lolu hlobo lwe-valve lubizwa nge-rotary stem gate valve noma i-valual valve ye-mbala emnyama.

Ukufakwa kanye nokunakekelwa kwama-valves wesango
1. Ama-Handwheels, izibambo kanye nezinqubo zokuhambisa azivunyelwe ukusetshenziselwa ukuphakamisa, futhi ukushayisana kuvinjelwe ngokuphelele.

4. Okwe-Gate Valves ngezinqubo zokuhambisa, ziwafake ngokwazo ngokuya nge-Product Instration Manual.
I-5. Uma i-valve isetshenziswa kaningi ivaliwe futhi icishwe, igcobe okungenani kanye ngenyanga.
