Kakaretso ea sebopeho sa sefahleho sa pheletso ea khokahano ea valve

Sebopeho sa holim'a li-valve se ama ka ho toba ts'ebetso ea ho tiisa li-valve, mokhoa oa ho kenya le ho tšepahala tsamaisong ea liphaephe.TWSe tla hlahisa ka bokhuts'oane liforomo tse kholo tsa khokahano le litšobotsi tsa tsona sehloohong sena.

I. Flanged Connections

Mokhoa oa ho hokahanya bokahohleng o fihlella ho tiisoa ka ho tiisa ka bolt ea li-flange tse pentiloeng.

Mefuta e tloaelehileng ea ho koala sefahleho:

- Sebaka se hlahelletseng: Moqapi o tloaelehileng ka ho fetisisa, o nang le sebaka sa ho tiisa se hlahelletseng ka 2-3mm, se loketseng mefuta e mengata ea khatello (PN10-PN25).

-Concave-convex bokaholimo: ts'ebetso e ntle ea ho tiisa, e loketseng mecha ea litaba e tukang le e chefo.

-Groove bokaholimo: tiiso e ntle ka ho fetisisa, e sebelisetsoang mecha ea litaba e kotsi haholo le maemo a khatello e phahameng.

-Ring mabapi le bokaholimo: Metal ring gasket, e etselitsoeng lits'ebetso tsa khatello e phahameng le mocheso o phahameng. Melemo: Ho tiisa ka botšepehi le ho qhaqholla habonolo.

Mefokolo: molumo o moholo le boima, theko e phahameng.

II.Khokahano ea Wafer

Belofo e na le moralo o se nang flanged, o sirelelitsoeng ke liboutu tse telele lipakeng tsa liphaephe. Litšobotsi tsa bohlokoa li kenyelletsa sebopeho se kopaneng, kaho e bobebe, le ho baballa litšenyehelo. Leha ho le joalo, e hloka litekanyetso tse phahameng tsa ho kenya 'me ho thata ho e boloka. Moralo ona o sebelisoa haholo holi-valve tsa serurubelelehlahloba li-valve.

III.Khokahano e Mehala

Khokahano ea likhoele ke mokhoa oa khokahanyo oa mochini o sebelisang li-fasteners tse kentsoeng ho hokela likarolo mme o ka aroloa neng kapa neng.

Melemo ea ho tiisa: Tlhahiso e kholo e etsa hore theko ea tlhahiso e be tlase haholo, e leng e 'ngoe ea mekhoa e sebetsang ka ho fetisisa ea ho hokahanya.

Mefokolo: Ho bonolo ho itokolla tlas'a ho sisinyeha le boima ba tšusumetso, 'me khatello ea kelello motsong oa khoele e etsa hore matla a eona a mokhathala a be tlaase.

IV. Lihokelo tsa Welding

Khokahano e tšepahalang ka ho fetesisa.

-Type: Butt welding: Matla a phahameng, ho hanyetsa metsi a tlaase, ho loketse maemo a thata a ho sebetsa.

-Plug-in welding connection: Ho bonolo ho e kenya, e loketseng liphaephe tse nyenyane tsa bophara. Melemo: Zero dutla, e thibela ho sisinyeha.

Litšitiso: 5. Bothata ba ho qhaqha. Mefuta e meng ea khokahanyo: Lihokelo tsa clamping: E ​​sebelisoa liindastering tsa bohloeki ho hloekisa habonolo. Khokahano ea matsoho: E sebelisoa ho lisebelisoa tsa lisebelisoa le li-hydraulic system.

Lintlha tsa khetho:

1. Khetha mokhoa ho ea ka khatello le mocheso: khatello e phahameng le mocheso o phahameng o lokela ho kenngoa kapa ho kopanngoa ha lesale.

2. Ho ipapisitsoe le litšoaneleho tse mahareng: Bakeng sa mecha ea litaba e kotsi, ho khothaletsoa li-welding kapa libaka tse kopaneng tsa tenon.

3. Nahana ka ho kenya le ho hlokomela: Ho qhaqha khafetsa ha khokahanyo ea flange.

4. Litšenyehelo le Sebaka: Sephaphatha se na le chelete e ngata ebile se kopane.

V. Qetello :

Khokahano e nepahetseng ke senotlolo sa polokeho ea liphaephe le ts'ebetso. Fumana tataiso ea litsebi le mantsoe a qotsitsoeng a tlholisano ho ronaserurubele belofo, belofo ea heke, lehlahloba li-valve. IkopanyeTWSho fumana tharollo e phethahetseng bakeng sa litlhoko tsa hau.
