Mokhoa oa ho Khetha Valve e Nepahetseng ea Marine

Ho khetha valve e nepahetseng ea likepe ho bohlokoa bakeng sa ho netefatsa ts'ebetso e sireletsehileng, e sebetsang hantle le e tšepahalang likepeng le lits'ebetsong tsa leoatleng. Ka mefuta e mengata ea li-valve le lits'ebetso indastering ea likepe - ho tloha lits'ebetsong tsa ballast ho ea lipotolohong tsa ho pholisa, lithapo tsa mafura le tšireletso ea mollo - ho etsa khetho e nepahetseng ho itšetlehile ka lintlha tse 'maloa tsa bohlokoa.

1. Utloisisa Tšebeliso le Medium

Sistimi e 'ngoe le e 'ngoe ea likepe e sebetsana le mofuta o itseng oa mokelikeli (metsi, oli, mafura, mouoane, jj.) ka khatello e fapaneng, mocheso le sekhahla sa phallo.

Ipotse:

• ①Ke mofuta ofe oa sesebelisoa se phallang ka har'a valve? (mohlala, metsi a leoatle, metsi a hloekileng, oli, mafura, khase, mouoane)

• ②Na se mahareng sea bola, se hlaba, kapa sea tuka?

• ③Na ke sistimi ea bohlokoa ea polokeho (mohlala, ho tima mollo, ho tima mafura, ho tima peterole)?

Keletso:Bakeng sa litsamaiso tse senyang kapa tsa metsi a letsoai, khethaboronse, koporokapali-valve tsa tšepe e sa hloekang.

2. Khetha Mofuta o Loketseng oa Valve

3. Nahana ka ho Tsamaellana ha Lintho

Libaka tsa leoatle li hloka thepa e sa senyeheng ke mafome ka lebaka la ho pepesehela metsi a letsoai khafetsa, mongobo le liphetoho tsa mocheso.

• ①Boronse/Koporo – E hanyetsa mafome hantle, e atile haholo lits'ebetsong tsa metsi a leoatle

• ②Tšepe e sa Khaotseng – E tšoarella hantle ebile e hanyetsa, e loketse maro a nang le khatello e phahameng kapa a senyang

• ③Tšepe e Lahliloeng – E theko e tlase, empa e loketse maro a sa senyeheng feela

• ④Tšepe ea Duplex/Super Duplex – Li-alloy tse sebetsang hantle bakeng sa lits'ebetso tse feteletseng

Keletso:Kamehla bapisa thepa ea valve le liphaephe le sephara ho qoba ho bola ha galvanic.

4. Lekola Litlhahlobo tsa Khatello le Mocheso

• ① Hlahloba PN (Khatello Nominal) kapa Tekanyetso ea Sehlopha

• ②Netefatsa mocheso o sebetsang

Li-valve li tlameha ho fihlela kapa ho feta litlhoko tsa sistimi le ho latela maemo a mokhatlo oa lihlopha.

5. Netefatsa Litumello tsa Mokhatlo oa Tlhophiso

Li-valve tsohle tsa metsing li tlameha ho fihlela maemo a machaba a polokeho ea metsing 'me li amoheloe ke Mekhatlo e amehang ea Lihlopha, joalo ka:DNV (Norway).ABS (USA).BV (Fora).Ngoliso ea Lloyd (UK).CCS (Chaena)

Keletso:Netefatsa hore moetsi o fana ka litokomane tsa setifikeiti bakeng sa valve ka 'ngoe.

6. Khetha Moetsi oa Valve ea Marine ea Tšepahalang

Khetha mofani oa li-valve tsa leoatleng ea:

• ①O na le boiphihlelo ba lilemo tse mashome indastering

• ②E fana ka mokhoa oa ho iketsetsa sesebelisoa sa hau

• ③E fana ka li-valve tse netefalitsoeng, tse lekiloeng le tse ngotsoeng

• ④E tšehetsa tšebeletso ea kamora thekiso le boeletsi ba botekgeniki

Qingdao I-FLOWke moetapelemoetsi oa li-valve tsa leoatlengka boiphihlelo ba lilemo tse fetang 10. Re fana ka mefuta e felletseng ea li-valve tsa leoatle tse netefalitsoeng, ho kenyeletsoa li-valve tsa heke, li-valve tsa globe, li-valve tsa serurubele, li-valve tsa check, li-valve tsa sefefo, le tse ling - tse sebeletsang likepe linaheng tse fetang 40 ka litifikeiti tsa CE, DNV, ABS, le LR.
