Indlela Yokukhetha Usayizi Ofanele We-Knife Gate Valve Kuzinhlelo Zokusebenza Zasolwandle

Kobunjiniyela basolwandle, yonke ingxenye efakwe emkhunjini ithinta ukuthembeka, ukuphepha, kanye nokusebenza kahle kohlelo. Phakathi kwalezi zingxenye ezibalulekile,ivalvu yesango lommeseidlala indima eyingqayizivele—ikakhulukazi ezindaweni lapho kukhona khona imithombo yamanzi eqinile, eqinile, noma eqinile. Kusukela kumapayipi amanzi aqinile kuya ezinhlelweni zamanzi angcolile, ukuthuthwa kwamanzi angcolile, imigqa yokudonsa amanzi, kanye nokudluliselwa kodaka, amavalvu esango lommese aqinisekisa ukulawulwa kokugeleza okuzinzile kanye nokuvalwa okuthembekile ngisho nangaphansi kwezimo ezinzima. Ukukhetha okulungileuhloboi-valve yesango lommese ibalulekile, kodwa ukukhethausayizi ofaneleyilokho okunquma ukusebenza kwesikhathi eside kanye nokuhambisana kwesistimu.

Ukuqonda Indima Yama-Knife Gate Valve Ezinhlelweni Zasolwandle

Amavalvu esango lommese aklanywe ngesango elibukhali elikwazi ukusika izinto eziqinile ezilengayo, imfucumfucu, noma udaka. Lokhu kuwenza afaneleke kakhulu ku:

• ①Izinhlelo zokuhlanza amanzi ze-Ballast

• ②Amapayipi amanzi angcolile olwandle kanye nendle

• ③Ukuthutha i-dredging kanye ne-slurry

• ④Izinhlelo zokukhipha amanzi egumbini lenjini

• ⑤Izifunda zamanzi ezipholile ezindaweni ezinezihlabathi eziningi

Ikhono labo lokunikeza ukugeleza okugcwele kanye nokwehla okuncane kwengcindezi kwenza izinqumo zobukhulu zibaluleke kakhulu.

Izinto Ezibalulekile Okufanele Uzicabangele Ngokulinganisa I-Knife Gate Valve Ezicelweni Zokusebenzisa Imikhumbi

1. Qondanisa Usayizi Wevalvu Nobubanzi Bephayiphi—Kodwa Qinisekisa Izidingo Zokugeleza

Nakuba ama-valve esango lommese evame ukukhethwa ukuze afane nobubanzi obujwayelekile bombhobho, ukusetshenziswa kwasolwandle kuvame ukuhilela:Ukugeleza kodaka.Ukuhlushwa okukhulu kwenhlabathi.Ingcindezi eguquguqukayo.Ukusebenza ngezikhathi ezithile

Ngenxa yalezi zici, ububanzi bangaphakathi obusebenzayo bepayipi kanye nevalvu kufanele buqhathaniswe. Imbobo yangaphakathi engaqondile kahle ingabangela ukuxokozela, ukuvinjelwa kokugeleza, noma ukunqwabelana kwezinto eziqinile.

Umkhuba omuhle kakhulu:Khetha ivalvu enembobo ehambisana kahle ne-ID yephayiphi ukuze igcine ukugeleza okubushelelezi futhi igweme ukuvaleka.

2. Hlola Izinga Lokugeleza Nezidingo Zejubane

Izinhlelo zasolwandle ziyahluka ezinhlelweni zezimboni ngoba zivame ukusebenza:Uma ucindezelekile kancane.Ngezinga lokugeleza elishintshashintshayo.Ngemidiya equkethe izinto eziqinile.

Amavalvu esango lommese awalungele ukugoba. Ngakho-ke, ukukhetha usayizi ofanele kuqinisekisa ukuthi ukugeleza okudingekayo kudlulangaphandle kokudinga ukuvulwa kwevalvu engaphelele, okungabangela ukuguguleka okusheshayo.Uma ijubane liphansi kakhulu, inhlabathi ingase ihlale; uma iphakeme kakhulu, kungase kube nokuguguleka. Usayizi ofanele ugcina ijubane lingaphakathi kwebanga elifanele.

3. Cabanga ngesilinganiso sokucindezela kanye nokwehla kokucindezela kwesistimu

Amavalvu esango lommese ezindaweni zasolwandle avame ukutholakala emigqeni ephansi yokucindezela

Khetha ivalvu equkethe:

• ①Ihambisana nesigaba sokucindezela kwephayiphi (PN10, PN16, njll.)

• ②Yehlisa ukwehla kwengcindezi ku-valve

• ③Igcina ukuvala kuqinile lapho kucindezeleke khona, lapho ama-valve amaningi ehluleka khona

Ivalvu enobukhulu obufanele ivumela ipayipi ukuthi ligcine ukusebenza okuzinzile ngaphandle kokulayisha ngokweqile amaphampu noma ukunciphisa amandla okugeleza.

4. Hlaziya Izici Zemidiya—Zithonya Usayizi

Imidiya ezinhlelweni zasolwandle ingafaka:Amanzi e-ballast anesihlabathi noma udaka.Amanzi amdaka noma indle.Amanzi okupholisa enjini aqukethe ukukhula kolwandle.I-slurry eqoshiwe

Okuqukethwe okuphezulu kwezinto eziqinile kudinga:Usayizi ogcwele.Akukho ukunciphisa indlela yokudlula.Ukukhetha i-valve enomkhawulo wesango oqinile kanye nesihlalo esiqinisiwe

Uma ukusetshenziswa kuhilela izinto eziqinile eziphakeme, ukukhushulwa ngosayizi owodwa ojwayelekile kunganconywa kuphela uma kusekelwa kahle yizibalo zokugeleza.

5. I-akhawunti Yesikhala Sokufaka kanye Nendlela Yokusebenza

Emikhumbini, isikhala sincane. Amakamelo enjini, izindawo zokugcina imithwalo, kanye nokufakwa ngaphansi kwedekhi kuvame ukuvimbela:Ukuphakama kwevalvu.Ukubekwa kwe-Actuator.Ukufinyeleleka kokulungiswa

Ngaphambi kokuqedela usayizi wevalvu:

• ①Qinisekisa ukuthi isondo lesandla, isilinda somoya, noma i-actuator kagesi ivuliwe

• ②Hlola ukungahambisani kahle kwepayipi

• ③Cabanga ngebanga eliya ezikhungweni ezinkulu, amaphampu, kanye namathangi

Ivalvu enobukhulu obufanele kumele ilingane ngokomzimba ngaphandle kokubeka engcupheni ukufinyeleleka noma ukuphepha.

6. Cabanga Ngezidingo Zenhlangano Yokuhlela

Amavalvu esango lommese wezinga lolwandle kumele ahlangabezane nezindinganiso ezivela ezinhlanganweni ezifana nalezi:I-DNV.I-ABS.LR.BV

Lezi zindinganiso zithonya:Izilinganiso zokucindezela/zokushisa ezivunyiwe.Ubukhulu bodonga obuncane.Ukukhetha izinto zokusetshenziswa emanzini olwandle (isb., i-SS316, insimbi engagqwali ephindwe kabili, izinketho zethusi)

Usayizi ofanele uhlanganisa ukukhetha ivalvu eqinisekisiwe ngezimo zokusebenza komkhumbi.

7. Hlola Ukuhambisana Kokuphela Kokuxhumeka

Amapayipi olwandle angasebenzisa:Iziphetho ezigobile (ezivamile nezinconywayo).Uhlobo lwe-Lug (oluvame kakhulu ezinhlelweni zemishini engaphakathi).Uhlobo lwe-wafer (lokufakwa okuncane)

Qinisekisa:Amaphethini e-bolt ahambisana nama-flange akhona.Ukungabikho kokuphuma kwangaphakathi kunciphisa usayizi wembobo osebenzayo.Uhlobo lwe-gasket lufanelana nemidiya

Usayizi ofanele udinga ukuhambisana kuzo zonke izindawo zokuxhuma.

Kungani Ukulinganisa Okufanelekile Kubalulekile Ezicelweni Zasolwandle

Ivalvu yesango lommese engalingani kahle ingaholela ku:

• ①Ukuvinjelwa kokugeleza

• ②Ukwanda kokunqwabelana kwenhlabathi

• ③Ukuguguleka kwevalvu ngaphambi kwesikhathi

• ④Ukudlidliza nomsindo

• ⑤ Ukusetshenziswa kwamandla aphezulu kwephampu

• ⑥Izingozi zokuphepha ohlelweni lwe-ballast noma lwe-drainage

Ivalvu enobukhulu obufanele inikeza:

• ①Ukulawula ukugeleza okuzinzile

• ②Ukuvala okuthembekile ngisho nasezindaweni ezingcolile

• ③Izindleko zokulungisa ezincishisiwe

• ④Impilo yesevisi ende

• ⑤Ukuhambisana nezindinganiso zasolwandle

Kubunjiniyela basolwandle—lapho ukuthembeka kusho ukuphepha—usayizi ofanele awunakuxoxiswana ngawo.
