Haeba u ntse u tsilatsila ho khetha li-valve tsa heke tse entsoeng ka tšepe kapa li-valve tsa heke tsa tšepe (WCB), ka kopo sheba feme ea zfa valve ho hlahisa phapang e kholo lipakeng tsa tsona.

1. Ho qapa le ho lahla ke mekhoa e 'meli e fapaneng ea ho sebetsa.

Casting: Tšepe e futhumatsoa ebe e qhibiliha ebe e tšeloa ka har'a hlobo ea lehlabathe kapa hlobo. Ka mor'a ho pholile, e tiea ho ba ntho. Likoti tsa moea li hlahisoa habonolo bohareng ba sehlahisoa.
Forging: Haholo-holo ho sebelisa mekhoa e kang hammering ka lithempereichara tse phahameng ho etsa tšepe ka workpiece le sebōpeho se itseng le boholo boemong ba polasetiki, le ho fetola litšobotsi tsa eona tsa 'mele.

2. Phapang ea ts'ebetso pakeng tsa li-valve tsa heke tse entsoeng leLi-valve tsa heke tsa WCB

Nakong ea ho qhekella, tšepe e na le deformation ea polasetiki, e nang le phello ea ho hloekisa lijo-thollo, kahoo hangata e sebelisoa ho etsa lintho tse se nang letho tsa likarolo tsa bohlokoa. Casting e na le litlhoko tsa lisebelisoa tse lokelang ho sebetsoa. Ka kakaretso, tšepe e entsoeng ka tšepe, aluminium, joalo-joalo e na le thepa e ntle ea ho lahla. Casting ha e na melemo e mengata ea ho qhekella, empa e ka etsa likarolo tse nang le libopeho tse rarahaneng, kahoo hangata e sebelisoa ha ho etsoa likarolo tsa tšehetso tse sa hlokeng thepa e phahameng ea mochini.

2.1 Khatello

Ka lebaka la ho se tšoane ha thepa ea thepa, li-valve tsa tšepe tse entsoeng ka tšepe li ka mamella matla a maholo, 'me polasetiki ea tsona, boima le lisebelisoa tse ling tsa mochini li phahame ho feta tsaLi-valve tsa WCB. Ka hona, e ka sebelisoa maemong a phahameng a khatello ea mosebetsi. Maemo a khatello a sebelisoang ka tloaelo a li-valve tsa tšepe tse entsoeng ke: PN100; PN160; PN250; PN320; PN400, 1000LB~4500LB. Likhatello tse sebelisoang hangata tsa li-valve tsa WCB ke: PN16, PN25, PN40, 150LB~800LB.

2.2 Diameter Nominal

Hobane mokhoa oa ho qhekella o na le litlhoko tse phahameng holim'a hlobo le lisebelisoa, bophara ba li-valve tse entsoeng hangata bo ka tlase ho DN50.

2.3 Matla a ho thibela ho lutla

Ho khethoa ke ts'ebetso ka boeona, ho lahla ho na le tšekamelo ea ho hlahisa blowhole nakong ea ts'ebetso. Ka hona, ha ho bapisoa le mokhoa oa ho forging, matla a ho thibela ho lutla ha li-valve ha a tšoane le a li-valve tse entsoeng.
Ka hona, liindastering tse ling tse nang le litlhoko tse phahameng tsa ho thibela ho lutla, tse kang khase, khase ea tlhaho, peterole, lik'hemik'hale le liindasteri tse ling, li-valve tsa tšepe tse entsoeng ka tšepe li 'nile tsa sebelisoa haholo.

2.4 Ponahalo

Li-valve tsa WCB le li-valve tsa tšepe tse entsoeng ka tšepe li fumaneha habonolo ka ponahalo. Ka kakaretso, li-valve tsa WCB li na le ponahalo ea silevera, ha li-valve tsa tšepe tse entsoeng li na le ponahalo e ntšo.

3. Liphapang mafapheng a kopo

Khetho e khethehileng ea li-valve tsa WCB le li-valve tsa tšepe tse entsoeng li itšetlehile ka sebaka sa ho sebetsa. E ke ke ea hlalosoa ka kakaretso hore na ke masimo afe a sebelisang li-valve tsa tšepe tse entsoeng le hore na ke masimo afe a sebelisang li-valve tsa WCB. Khetho e lokela ho ipapisa le maemo a khethehileng a ho sebetsa. Ka kakaretso, li-valve tsa WCB ha li hanyetsane le asiti le alkali 'me li ka sebelisoa feela liphaepheng tse tloaelehileng, ha li-valve tsa tšepe tse entsoeng ka tšepe li khona ho mamella khatello e phahameng' me li ka sebelisoa lifemeng tse ling tse nang le mocheso o phahameng, joalo ka limela tsa motlakase le limela tsa lik'hemik'hale. Belofo ea sehlopha.

4. Theko

Ka kakaretso, theko ea li-valve tsa tšepe tse entsoeng ka tšepe e phahame ho feta ea li-valve tsa WCB.
