ITape yokuPakisha iValve yeGraphite
1. Isishwankathelo seMveliso
Material: Igraphite eguquguqukayo esulungekileyo (umcu -isixhobo sokutywina esimile)
Ulwakhiwo: Ipateni eyodwa yamacangci kumphezulu
Injongo yoyilo: Kwindawo yegland yeevalvu zoshishino, iimpompo, izixhobo ezijikelezayo
Ixabiso eliPhambili: Ukusebenza kokutywinwa okugqwesileyo, ubomi benkonzo ende, ukufakwa lula; ngokwakho-ukuthambisa, ubushushu obuphezulu/ukumelana nokubola; indawo efanelekileyo yokupakishwa kwendabuko (i-asbestos, i-PTFE) kwizicelo ezifunayo
2. Iimpawu eziphambili kunye nezinto eziluncedo
Ukutywinwa kokuSebenza: Igraphite eguquguqukayo ilingana nesiqu sevalvu kunye nodonga lwebhokisi yokupakisha ngokugqibeleleyo; igcina ukutywinwa okulungileyo phantsi kokuguquguquka koxinzelelo okanye ukuguga okuncinci kwesikhondo sevalve
Ukumelana neqondo lobushushu: Imo engasebenziyo: -200℃ukuya +500℃; okusingqongileyo oxidizing: kucetyiswa Ngaphantsi okanye ukulingana +400 isidanga /{3}} isidanga; akukho kunyibilika, ukuqina okanye ukuthotywa
Self-ukuthambisa: Graphite (i-lubricant eqinileyo) yehlisa ivalve stem friction & torque yokusebenza; iqinisekisa ukusebenza kakuhle, ikhusela i-valve stem ekugugile
I-Chemical Inertness: Ixhathisa kakhulu kwii-asidi ezahlukeneyo, i-alkali, i-solvents, i-organic compounds; ilungele iinkqubo zemichiza ezonakalisayo
Ufakelo: Isakhiwo esibiyelweyo esinokuguquguquka okuphezulu kunye nokuqina; lula ukusonga isiqu sevalve, ihambelana nokupakishwa kwejometri yebhokisi; akukho zixhobo zikhethekileyo ezifunekayo
Ubomi benkonzo: Anti{0}}ukuguga, ukumelana nemijikelo yobushushu kunye nokothuka koxinzelelo; kunciphisa ukugcinwa kwexesha lolungiso, ukuphindaphindeka kokutshintshwa kunye neendleko zobunini zizonke
3. Izicelo eziphambili
Isetyenziswa kakhulu kwiivalvu zamashishini ezifuna ukutywinwa okuthembekileyo, kubandakanywa kodwa kungaphelelanga apho:
Ikhemikhali kunye nePetrokhemikhali: iivalufa (isango, iglowubhu, ibhola, ulawulo) kwiireactors, imibhobho, iimpompo
IsiVeliso soMbane: Vuthela-iivalvu, iivalvu zesixokelelwano somphunga kwizixhobo zombane
Amachiza kunye noKutya: Iivaluvu zococeko{0}}kwizicelo ezibalulekileyo
Metallurgical:{0}}iqondo lobushushu eliphezulu iivalvu zomoya oshushu, iivalvu zegesi
Iphepha: Iivalvu zenkqubo yokuphatha imichiza eyonakalisayo
