Ho Utloisisa Maemo a Indasteri bakeng sa Li-valve tsa Check

I.Litekanyetso tsa API

American Petroleum Institute (API) e fana ka litekanyetso tse 'maloa tsa bohlokoa bakeng sahlahloba li-valve, haholo indastering ea oli le khase:

• API 594: Tekanyetso ena e akaretsa moralo, lisebelisoa, boholo le litlhoko tsa tlhahlobo bakeng sa li-valve tsa cheke, ho kenyeletsoa ho swing, li-plate tse peli le li-valve tsa cheke. E etsa bonnete ba hore li-valve li finyella litekanyetso tse phahameng tsa ho thibela khatello, bokhoni ba ho koala, le ho tšepahala ha ts'ebetso.

• API 6D: Tekanyetso ena e etselitsoe lipeipi le lits'ebetso tsa lipeipi, ho netefatsa hore li-valve tsa cheke li fihlela litlhoko tsa ts'ebetso e phahameng bakeng sa liphaephe tsa oli le khase tsa sebaka se selelele, li-refineries le liindasteri tsa petrochemical.

• API 608: Tekanyetso ena e sebetsa ho li-valve tsa bolo ea tšepe, ho kenyelletsa le meralo e phaphametseng le e kentsoeng ka trunnion, e nang le lipheletso tse nang le flanged le butt-welding. E totobatsa litlhoko tsa 'mele oa li-valve, setulo, tiiso le lisebelisoa tsa bolo, jometri ea boema-kepe, mekhoa ea liteko, likhatello / litekanyetso tsa mocheso le matšoao.

II. Litekanyetso tsa ASME

The American Society of Mechanical Engineers (ASME) e fana ka litlhoko tse qaqileng bakeng sa moralo, thepa, boholo le liteko.hlahloba li-valve:

• ASME B16.34: Tekanyetso ena e akaretsa moralo le litekanyetso tsa khatello bakeng sa li-valve tsa cheke, ho netefatsa hore lia lumellana le ho fapanyetsana ho bahlahisi ba fapaneng.

• ASME B16.5: Tekanyetso ena e totobatsa litekanyo le litlhoko tsa liphaephe tse nang le liphaephe le li-fittings tse nang le mapheo, ho netefatsa ho kenngoa hantle le ho lumellana.

• ASME B16.10: Tekanyetso ena e fana ka litekanyo tse shebaneng le sefahleho le tsa ho qetela tsa li-valve, ho netefatsa ho tsamaisana hantle le ho kenya.

III. AWWA Litekanyetso

Mokhatlo oa American Water Works Association (AWWA) o fana ka litekanyetso ka ho khetheha bakeng sa likopo tsa ho hloekisa metsi:

• AWWA C508: Tekanyetso ena e akaretsa li-valve tsa ho hlahloba lits'ebeletso tsa metsi, ho netefatsa ts'ebetso e nepahetseng le polokeho lits'ebetsong tsa metsi tsa masepala.

• AWWA C510: Tekanyetso ena e totobatsa likopano tse thibelang ho khutla ha li-valve tse hlahlobang habeli, ho netefatsa ts'ireletso khahlanong le ho khutlela morao lits'ebetsong tsa phepelo ea metsi.

IV. Litekanyetso tsa EN

Melao ea Europe (EN) e fana ka tataiso bakeng sahlahloba li-valvee sebelisoa libakeng tse fapaneng tsa indasteri:

• TS EN 10204 3.1 Tekanyetso ena e fana ka litifikeiti tsa thepa tse bonts'ang sebopeho sa lik'hemik'hale le boleng ba tšepe e sebelisoang ka har'a valve.

• TS EN 12266-1 Tekanyetso ena e akaretsa liteko tsa khatello ea li-valve, ho netefatsa hore li khona ho sebetsana le khatello e boletsoeng ntle le ho lutla.

Mehato ea ho Netefatsa Boitšoaro

I. Khetho ea Lintho

Khetha lisebelisoa tse fihlelang litekanyetso tse hlokahalang bakeng sa ts'ebeliso ea hau e ikhethileng. Lisebelisoa tse tloaelehileng li kenyelletsa:

• Stainless Steel: E loketse ho hanyetsa kutu le lisebelisoa tsa mocheso o phahameng.

• Carbon Steel: E loketse lits'ebetso tsa khatello e phahameng.

• Alloy Steels: E sebelisoa bakeng sa matla le ho tšoarella ha tsona libakeng tse thata.

II. Maemo a Moqapi le a Tlhahiso

Netefatsa horehlahloba li-valveli entsoe le ho etsoa ho latela maemo a amehang a indasteri:

• API 594: Etsa bonnete ba hore moralo oa li-valve o kopana le litlhoko tse boletsoeng bakeng sa ho thibela khatello le ho tšepahala ha ts'ebetso.

• ASME B16.34: Netefatsa hore litekanyo tsa valve le likhatello tsa khatello li lumellana le maemo.

• TS EN 10204 3.1: Fumana litifikeiti tsa thepa ho netefatsa boleng le sebopeho sa lisebelisoa tsa valve.

III. Teko le Setifikeiti

Etsa tlhahlobo e phethahetseng 'me u fumane litifikeiti tse hlokahalang ho netefatsa hore ho latela melao:

• API 598: Etsa tlhahlobo ea ho lutla ho netefatsa hore li-valve li tiisa ka thata le ho fihlela litekanyetso tse hlokahalang.

• TS EN 12266-1: Etsa liteko tsa khatello ho netefatsa bokhoni ba valve ho sebetsana le khatello e boletsoeng ntle le ho lutla.

• ISO 9001: Kenya ts'ebetsong litsamaiso tsa taolo ea boleng ho netefatsa boleng bo tsitsitseng le ho latela lits'ebetso tsohle tsa tlhahiso.
