Mofuthu Flange Ball Valve

Melemo ea li-valve tsa bolo ea mouoane ke efe?

Li-valve tsa bolo ea fektheri ea Shenchi tse hanyetsanang le mocheso o phahameng oa mocheso li na le 'mele o entsoeng ka koporo e khethiloeng ka hloko, SUS304, kapa SUS316L, e nang le mokokotlo oa valve o entsoeng ka koporo kapa tšepe e sa hloekang. Ba na le tiiso ea mocheso o phahameng oa PPL, ba fumana ho lutla ha zero libakeng tsa mouoane ho fihla ho 250 ℃. Khokahano ea flange e matla ebile e ka tšeptjoa, e hanana le tšusumetso ea hamore ea metsi, e na le torque e tlase ea ho bula le ho koala le ts'ebetso e bonolo. Li-valve tsa Shenchi ha li na kutu ebile li na le khatello e phahameng ea khatello, li loketse marang-rang a liphaephe tsa mouoane, liteishene tsa mocheso oa mocheso, le maemo a mang a ts'ebetso, ho fokotsa haholo lebelo la tlhokomelo le ho etsa hore e be likarolo tse loketseng tsa ho thibela litsamaiso tsa mouoane.

PPL Tiiso ea Mocheso Range

Li-valve tsa bolo ea Shenchi steam flange hangata li sebelisa litiiso tsa PPL tse sebetsang hantle haholo. PPL (para-polystyrene) ke polasetiki ea boenjineri e hanyetsanang le mocheso o phahameng e nang le moeli oa mocheso o tlase oa hoo e ka bang -20℃. Ka holim'a mocheso ona, litiiso li boloka matla a matle a mochini le botsitso ba sebopeho. Ha mocheso o theoha ka tlase ho -20 ℃, thepa ea PPL butle-butle e lahleheloa ke ho tiea ha eona, e fetoha e brittle le e thata, e ka lebisang ho hloleheng ha tiiso.

Mabapi le ho hanyetsa mocheso o phahameng, PPL e khona ho mamella maemo a mocheso o phahameng oa 260 ℃-300 ℃ ka nako e telele, e sebetsa hantle haholo tlas'a maemo a mouoane a tletseng mouoane, ntle le ho nolofatsa kapa ho holofala joaloka PTFE e tloaelehileng. Bakeng sa maemo a hlokang esita le mocheso o tlase oa ts'ebetso, Shenchi e fana ka phetolelo ea tiiso ea EPDM e le mokhoa o mong; EPDM e ka mamella mocheso o tlase ho -40℃. Tlholisano ea mantlha ea valve ea bolo ea mouoane e tiisitsoeng haholo e mabapi le ho nyallana hantle ha thepa ea ho tiisa le maemo a ts'ebetso ea setšeng.

Mecha ea litaba e sebetsang le mocheso oa mocheso

Li-valve tsa bolo ea Shenchi steam flange li loketse mefuta e mengata ea mecha ea litaba, ho akarelletsa le metsi, moea, khase, oli, lino tse fapa-fapaneng, 'me haholo-holo, mouoane o tletseng metsi. Mocheso oa mocheso oa mecha ea litaba o akaretsa lithempereichara tse phahameng, tse mahareng, tse tloaelehileng le tse tlase, 'me ka sebele li finyella ho fana ka tšireletso e feletseng ea mocheso. Mabapi le khetho ea thepa ea ho tiisa: ha e na le litiiso tsa PPL, mocheso o sebetsang ke -20 ℃ ho 260 ℃, o nang le mocheso o phahameng oa nako e khutšoanyane oa 300 ℃, e leng se etsang hore e be tharollo e ratoang bakeng sa liphaephe tsa mouoane; ha e na le litiiso tsa EPDM, mocheso o sebetsang oa mocheso ke -40 ℃ ho ea ho 120 ℃, o etsa hore o tšoanelehe haholoanyane bakeng sa maemo a tlaase a mocheso, mekhoa ea metsi a chesang, kapa maemo a mouoane a tlaase.

Moetsi oa li-valve tsa li-valve tsa mouoane oa Sechaena Shenchi o khothalletsa bareki ho khetha thepa ea ho tiisa ho latela mocheso oa sebele oa ho sebetsa. Haeba o sa tsebe hantle hore na o ka khetha joang, o ka fana ka liparamente tse ikhethileng, 'me sehlopha sa tekheniki sa Shenchi se tla u khothaletsa tlhophiso e nepahetseng. Valve ea boleng bo phahameng ea mouoane oa flange ha ea lokela ho ba bopaki ba ho lutla ha mocheso o phahameng feela empa hape e ka tšeptjoa nakong ea ho qala mocheso o tlase; Khetho ea Shenchi's dual-seal e etselitsoe morero ona hantle.
