Mokhoa oa ho Khetha Li-valve tsa Ball bakeng sa Tšebeliso ea Sekepe

Indastering ea likepe, ho tšepahala le polokeho ha ho buisanoe. Karolo e 'ngoe le e 'ngoe—haholo-holo li-valve—e tlameha ho sebetsa ka mokhoa o tsitsitseng tlas'a maemo a thata a tikoloho. Har'a mefuta e fapaneng ea li-valve,li-valve tsa boloE ikhetha ka moralo oa eona o moqotetsane, ts'ebetso e bonolo, le ts'ebetso e ntle ea ho koala. Empa ka thepa le litlhophiso tse ngata tse fumanehang, u khetha valve ea bolo e nepahetseng joang bakeng sa ts'ebeliso ea sekepe

1. Nahana ka Tikoloho ea Leoatle

Libaka tsa leoatleng ke tse ling tsa maemo a thata ka ho fetisisa bakeng sa lisebelisoa life kapa life tsa mechini. Metsi a letsoai, mongobo, ho thothomela le ho feto-fetoha ha mocheso li ka potlakisa ho bola le ho tsofala.

Ka hona, mohato oa pele ke hokhetha thepa ea valvetse ka hanelang ho bola le ho boloka botsitso ba nako e telele:

• ①Li-valve tsa Borone tsa Bolo– Ho hanyetsa mafome hantle metsing a leoatle; ho loketse liphaephe tsa metsi a leoatle, litsamaiso tsa ballast, le litsamaiso tsa ho pholisa.

• ②316 Li-valve tsa Ball tsa Tšepe e sa Khaotseng– Ho hanyetsa mafome ka tsela e phahameng le matla a mechini; e loketse litsamaiso tsa khatello e phahameng le tsa lik'hemik'hale.

• ③Li-valve tsa Bolo ea Koporo– E theko e tlase bakeng sa tshebediso ya metsi a hlwekileng kapa a seng a lewatle empa ha e kgothaletswe bakeng sa tshebediso ya metsi a lewatle ka ho toba.

2. Khetha Mofuta o Loketseng oa Khokahano

Mofuta oa khokahano o khetholla hore na valve e kopana joang le sistimi ea liphaephe tsa sekepe. Likhetho tse tloaelehileng haholo ke:

• ①Li-valve tsa Ball tse Felletseng tse Felletseng– Fana ka dikgokelo tse matla tsa mechini le tlhokomelo e bonolo. E molemohali bakeng sa liphaephe tse kholo le litsamaiso tsa khatello e phahameng.

• ②Li-valve tsa bolo tse nang le khoele (tse nang le screwed)– E nyane ebile e loketse liphaephe tse nyane tse bophara le litsamaiso tse nang le khatello e tlase.

• ③Li-valve tsa Bolo tse Welded End– Fana ka dikgokelo tse se nang ho dutla bakeng sa ho kenya ka ho sa feleng, tse atisang ho sebediswa ditsamaisong tsa bohlokwa.

Ha ho tšepahala le bonolo ba ho qhaqha e le lintho tsa bohlokoa—joalo ka lits'ebetsong tsa ho pholisa kapa tsa metsi a leoatle—li-valve tsa bolo tse nang le flanged hangata lia khethoa.

3. Hlalosa Khatello le Thempereichara ea Sistimi

Mekhoa ea likepe e sebetsa tlas'a likhatello le mocheso o fapaneng. Ho khetha tekanyo e nepahetseng ea khatello ho netefatsa ts'ebetso e sireletsehileng le e tsitsitseng.

• Litekanyetso tsa ①PN16–PN40 li sebelisoa hangata lits'ebetsong tsa metsing.

• ②Bakeng sa litsamaiso tsa mafura a nang le khatello e phahameng kapa ea haeteroliki, li-valve tsa tšepe e sa ruseng tse lekantsoeng ka holimo ho PN40 lia khothaletsoa.

Ho phaella moo, nahana ka ho hanyetsa mocheso haeba valve e sebelisoa likamoreng tsa enjene kapa haufi le li-heat exchanger.

4. Khetha Moralo o Nepahetseng oa Valve

Moralo oa kahare oa valve o khetholla ts'ebetso ea eona ea ho koala, litšobotsi tsa phallo, le ho tšoaneleha bakeng sa maro a itseng.

• ①Li-valve tsa Bore Ball tse Felletseng– Fana ka phallo e sa thibeloang, e fokotsang tahlehelo ea khatello. E loketse litsamaiso moo phallo e sebetsang hantle e leng ea bohlokoa.

• ②Li-valve tsa Bore Ball tse Fokolitsoeng– E nyane ebile e boloka litšenyehelo bakeng sa tšebeletso e akaretsang.

• ③Li-valve tsa bolo tse phaphametseng– E tlwaelehile bakeng sa diphaephe tse nyane ho isa ho tse mahareng, tse fanang ka ho kwalwa ka thata.

• ④Li-valve tsa Ball tse fanyehiloeng ka Trunnion– E etselitsoe boholo bo boholo le litsamaiso tse nang le khatello e phahameng, e netefatsang ts'ebetso e tsitsitseng ea ho tiisa.

Bakeng sa litsamaiso tsa likepe moo katleho ea phallo le ts'epo ea ho tiisa li leng bohlokoa, li-valve tsa bolo tse phaphametseng tse nang le mokoti o felletseng ke mofuta o sebelisoang haholo.

5. Hlahloba Litifikeiti tsa Marine

Ha o sebetsa lewatleng, ho latela melao ho bohlokwa. Kamehla kgetha di-valve tse netefaditsweng ke balaodi ba tsa lewatle ba tsebahalang, tse kang:DNV (Det Norske Veritas).LR (Rejistara ea Lloyd) leABS (Lefapha la Amerika la ho Romela Likepe).Litifikeiti tsena li netefatsa hore valve e fihlela boleng ba leoatle, thepa le maemo a ts'ebetso.

6. Beha Pele Tlhokomelo le Ts'ebetso e Bonolo

Mekhoa ea likepe e hloka li-valve tse bonolo ho li sebelisa le ho li hlokomela, esita le libakeng tse koetsoeng.Li-valve tsa bolo li ratoa hobane li fana ka:

• ①Tshebetso e potlakileng ya ho kgutlela morao ka kotara

• ②Sebopeho se senyane bakeng sa libaka tse thata tsa ho kenya

• ③Litlhoko tse fokolang tsa tlhokomelo

Bakeng sa boiketlo, nahana ka li-valve tsa bolo tse nang le li-handle tse notlellang kapa li-operator tsa li-gear bakeng sa polokeho le taolo e eketsehileng.

Ho khetha valve e nepahetseng ea bolo bakeng sa tšebeliso ea sekepe ho itšetlehile ka motsoako oa lintlha—thepa, mofuta oa khokahano, tekanyo ea khatello, moralo, setifikeiti le boiketlo ba tlhokomelo.Phallo ea I ea Qingdao, re fana ka mefuta e mengata eali-valve tsa bolo tsa sehlopha sa leoatlee netefalitsoeng ke DNV, LR, le ABS, e etselitsoeng ho fana ka ts'ebetso e ikhethang lits'ebetsong tsa likepe. Ebang ke bakeng sa liphaephe tsa metsi a leoatle, lipotoloho tsa ho pholisa, kapa lithapo tsa mafura, li-valve tsa rona li netefatsa ts'ebetso e sireletsehileng le e sebetsang hantle leoatleng.
