Molao-motheo oa ho Sebetsa

Molao-motheo oa ts'ebetso oa feme ea Shenchi e thibelang ho bola ea litsela tse tharo tsa bolo ea flange e thehiloe holim'a likanale tse nang le sebopeho sa L kapa T tse entsoeng ka bolo. Bolo e behoa bohareng ba 'mele oa valve' me e potoloha ka letsoho. Ha bolo e ntse e potoloha, liteishene li ikamahanya le kapa li tima ho tloha likoung tse fapaneng tsa li-valve, li hlokomela ho fetoha, ho kopanya, kapa ho arohana ha tataiso ea phallo e bohareng.

Melemo ea Khokahano ea Flange:

Li-valve tsa bolo ea Shenchi 3-way flanged li sebelisa likhokahano tsa flange. Ha ho bapisoa le likhokahano tsa likhoele, likhokahano tsa flange li fana ka khanyetso e phahameng ea khatello; tekanyo ea PN16 e ka mamella khatello ea 1.6MPa ka mokhoa o tsitsitseng. Disassembly e loketse, e nolofalletsa tlhahlobo ea lipeipi tsa kamehla le tlhokomelo. Ho tiisoa ka botšepehi ho tiisitsoe; flange gasket le liboutu li sebetsa 'moho ho felisa kotsi ea ho lutla. E loketse liphaephe tsa bophara bo boholo; bakeng sa li-diameter tse ka holimo ho DN50, moo likhokahano tsa khoele li leng thata, li-flange ke khetho e tloaelehileng. Shenchi, moetsi oa li-valve tsa bolo ea litsela tse 3 oa Chaena, o fana ka li-flanges tse lumellanang le litekanyetso tsa ANSI, BS, DIN, le JIS, ho finyella litlhoko tsa bareki ba lefats'e.

Tlhophiso ea Ntlha ea 1: Ho tsamaisana le Flange

Ho lumellana ha Flange Ha u kenya valve ea bolo ea Shenchi ea litsela tse tharo, lifahleho tsa flange li tlameha ho lumellana. Li-flange tse peli li lokela ho ba tse bapileng le tse tsepamisitsoeng, 'me ho kheloha ho se ke ha feta sebaka se amohelehang sa gasket ea flange. Ho qobella ho lokisoa ha bolt ho tla baka ho fetoha ha 'mele oa valve, ho ama ho potoloha ha bolo le ts'ebetso ea ho tiisa. Ka mor'a ho lumellana, gasket e lokela ho behoa bohareng 'me e se ke ea senyeha. Theko e tlaase ea litsela tse tharo tsa flange ball valve ha e lekane le boleng bo tlaase; Lihlahisoa tsa Shenchi li fana ka ho nepahala ho phahameng le ho kenya habonolo. Li-valve tsa li-ball-way tse tharo tse sa khoneng ho bola li na le lithapo tse holimo tse fihlelang litekanyetso, tse netefatsang tiiso e tšepahalang haholoanyane.

Kenyelletso Ntlha ea Bobeli: Bolt Tightening

Liboutu tsa flange li tlameha ho tiisoa ka mokhoa o mosesane ka mekhahlelo. Sebelisa torque butle-butle ka mekhahlelo ea 2-3, ho latela tatellano ea diagonal ea 180 °. U se ke ua tiisa lehlakore le le leng ka nako e le 'ngoe, ho seng joalo khatello e sa lekaneng holim'a gasket e tla etsa likanale tsa ho lutla. Torque ea bolt e tlameha ho fihlela litekanyetso tse tloaelehileng; ho tiisa ho feta tekano ho tla senya flange kapa liboutu, athe ho tiea ka tlase ho tla etsa hore ho be le tiiso e sa lekaneng. Shenchi 3-way flange ball valve fektheri e fana ka tafole ea torque e khothalletsoang hore li-installer li bue ka tsona. Lintlha tsena tsa ho kenya li bohlokoa bakeng sa ho netefatsa ts'ebetso ea nako e telele ea li-valve tse sa lutleng; ka kopo latela lintlha ka botlalo.

Ntlha ea Tlhophiso ea 3: Tšehetso ea Liphaephe le Tlhoekiso

Pele o kenya, bokahare ba liphaephe bo tlameha ho hloekisoa ho tlosa slag ea welding, lithapo tsa tšepe, lehlabathe le litšila tse ling. Lintho tse tsoang kantle ho naha tse kenang ka sekoting sa valve li ka ngopa bolo kapa litiiso, tse lebisang ho lutla. Phaephe e tlameha ho tšehetsoa ka boikemelo; valve ha ea lokela ho jara boima ba phala. Li-valve tsa bolo ea li-tee-diameter tse kholo li boima; ho kokobela ha phaephe ho ka hula flange ho tloha bohareng, ho senya tiiso. Li-valve tsa tee tse thibelang ho bola li entsoe ka thepa ea WCB, SUS304, kapa SUS316L, e nang le mokokotlo oa koporo kapa oa tšepe e sa hloekang. Ka mor'a ho qeta lintlha tsa ho kenya, sebetsana se lokela ho potoloha ka bolokolohi ntle le ho jamming; belofo e se e loketse ho sebelisoa.
