I-valve yesango inezici zokumelana noketshezi oluncane, ingcindezi esebenzayo, izinga lokushisa, njll., ingenye yevalvu yokusika esetshenziswa kakhulu, esetshenziselwa ukunqamula noma ukuxhuma okuphakathi epayipini.Ukuncipha kobubanzi kunganciphisa ubukhulu bezingxenye, kunciphise amandla adingekayo ukuze kuvulwe futhi kuvalwe, futhi kwandise ububanzi bokusetshenziswa kwezingxenye.Kodwa-ke, ukulahleka kokumelana noketshezi kuyanda ngemva kokuncipha kobubanzi.I-valve yesango elinomfutho ophansi e-China ngokuvamile yenziwe ngensimbi ekhonjiwe, evame ukuba nezinkinga ezinkulu njengokuqhekeka komzimba okubanda nokuwa kwepuleti lesango.Isiqu se-carbon steel se-cast iron gate valve kulula ukugqwala, i-gasket yokupakisha ingeyekhwalithi embi, futhi ukuvuza kwangaphakathi nangaphandle kubi kakhulu.I-PN10 i-valve yesango lensimbi ephansi ye-carbon steel ekhiqizwa yi-Shanghai Hugong Valve Factory ithatha indawo ye-valve yesango lensimbi yendabuko, ixazulula ngokuphumelelayo izinkinga ezifana negobolondo le-valve yesango lensimbi ensimbi kulula ukuqhwa nokuqhekeka, ipuleti lesango kulula ukuwa, I-valve stem kulula ukugqwala, futhi ukusebenza kokuvala akuthembeki.

I-1, isisindo esilula: umzimba wenziwe nge-high class ibhola elimnyama lensimbi, isisindo singaphansi kuka-20% ~ 30% ngaphansi kwesisindo se-valve yesango, ukufakwa kalula nokugcinwa.

2. Ukupakishwa okuphelele: isango lithatha irabha yekhwalithi ephezulu yerabha yangaphakathi nangaphandle iyonke.Ubuchwepheshe be-European class vulcanization yenjoloba buqinisekisa usayizi onembile wejiyomethri wesango elivuvukele, futhi inqama yokukhipha irabha ne-ductile ithembekile, akulula ukuwa futhi ibe nenkumbulo enhle enwebekayo.

I-3, ibhulokhi yebhuleki yohlobo oluyisicaba: isango lendabuko livame ukugeza ishubhu emanzini ngemuva kwezinto zangaphandle ezifana netshe, ukhuni, usimende, amafayili ensimbi, i-sedimentation engaphansi kwe-valve efana nezikhala, kulula ukuyibangela ayikwazi ukuvala ngokuqinile. futhi yakhe into exegayo, ngaphansi kophawu lwamavalvu esango lesihlalo esinwebekayo esinepayipi lamanzi elinomklamo oyisicaba, akulula ukubangela ukuchithwa kwemfucumfucu, kwenze ukugeleza kungavinjelwa.

I-4, umzimba we-valve yokutshala imali: umzimba we-valve wamukela ukunemba kokusakazwa, usayizi wejiyomethri oqondile wenza umzimba we-valve ngaphandle kokuqedwa ungaqinisekisa ukuvalwa kwe-valve.
