I-valve yesihlalo sensimbi ikhethelwa indawo esindayo efana nezinhlayiya eziqinile, ukuqubuka, izinga lokushisa eliphezulu noma isigaba somfutho ophakeme noma nanoma ubani onalesi simo esishiwo sihlanganisiwe, ipayipi elivamile njengamakhemikhali amalahle, i-pulp & paper kanye nendawo yokuhluza uwoyela ongahluziwe njll.I-QL ivalvu yesihlalo sensimbi ikhombisa ukusebenza kahle kokuvala, isevisi yesikhathi eside, itorque ephansi kanye nokuncipha kwengcindezi ngokuqhathaniswa kusevisi eshiwo ngenhla.Ivalvu evamile njengeglobhu kanye ne-valve yesango ayikwazanga ukuhlangabezana nesimo esinjalo sokusebenza, ngakho-ke i-valve yesihlalo sebhola yensimbi ikhulisa izidingo ezengeziwe zesevisi enzima.
- I-valve yebhola yensimbi esebenza kahle kakhulu ye-ARAN ifaka uphawu lwensimbi ukuya kwensimbi phakathi kwezihlalo nebhola lomhlangano wamavalvu.
- ● Ngokwezimo zokusebenza ezihlukene, i-QL isebenzisa ibhola elithuthukisiwe kanye nenqubo yokuhlanganisa ubulukhuni besihlalo, indawo evamile izoba ngaphezu kwe-HRC 60, futhi ubuningi buzoba ngaphezu kwe-HRC 74. Indawo yokuvala iqiniswa yizinhlobo zama-coating ezifana ne-CRC, TCC, I-STL6,Ni 60, i-STL embozwe ngembondela, njll.
- ● Icebo le-HVOF elincanyelwayo (isivinini esiphezulu se-oxygen-fuel) enamathela okokusebenza kwe-chromium carbide CRC, i-tungsten carbide TCC/Cr3C2, i-stellite eqinile ebheke i-Ni60 enobulukhuni obungu-68-74 HRC nokunameka 02-0.25mm.Ingxubevange esekelwe ku-nickel esekelwe kubuchwepheshe be-thermal spray welding ukujiya koqweqwe olujwayelekile lokuhlanganisa cishe ku-0.5~1.0mm, ubulukhuni bungafinyelela ku-HRC55~65, futhi amandla okubopha angaba ngu-400MPa.Lezi zinto zinokushisa okuphezulu okuhle kakhulu kanye nobulukhuni bengcindezi ephezulu, ukugqwala nokumelana nobude besikhathi.

- ● I-valve yebhola evala isihlalo sensimbi idinga umshini omuhle kanye nokugaywa kwebhola ukuze kuqinisekiswe ukuvaleka okuqinisekile kokuhlolwa kokusebenza kokuvuza kwebhamuza eliqinile elinguziro.
- ● I-Butterfly spring noma i-spring loaded design ekwakhiweni kokuvala isihlalo susa i-valve yebhola ebhajwe ukushisa okuphezulu kokushisa.
- ● I-valve yebhola entantayo yesihlalo sensimbi inesakhiwo sokuvala isihlalo ngemuva kwesiphetho se-inlet yebhola, futhi iyisigxivizo sendlela eyodwa futhi isiqondiso sokugeleza sisemzimbeni wevalvu.Uma amakhasimende enezidingo ezikhethekile, isakhiwo sokuvala uphawu sezindlela ezimbili singakhiqizwa.
- ● Ivalvu yesihlalo sesihlalo se-trunnion ngokuvamile inokwakheka kokuvala isihlalo ekugcineni kwebhola lokungena.Izihlalo ezimbili zingakwazi ukusika ngokuzimela okuphakathi endaweni yokungena kanye nokuphuma ekugcineni ukuze kuzuzwe umsebenzi wokuvimba kabili.Lapho i-valve yebhola ivaliwe, ngisho noma iziphetho zombili zokungena nokuphuma kwe-valve zicindezelwa ngasikhathi sinye, umgodi ophakathi we-valve kanye namaphaseji emikhawulweni yomibili ingavinjelwa komunye nomunye, futhi okuphakathi okusele ngaphakathi. umgodi ophakathi ungakhishwa ngama-valve okusiza.

- Ukuqedwa kwe-Ball Surface Ngaphansi kuka-Ra 0.2, I-Ball Roundness ingaphansi kuka-0.02mm
- ● I-valve yesihlalo sokushisa ephansi yohlobo lwensimbi, izinga lokushisa eliphakathi lifinyelela ku-196 ℃, umzimba we-valve nezingxenye zangaphakathi ziphathwa nge--196 design degree liquid nitrogen lokushisa eliphansi lokushisa cryogenic treatment, kanye ne-valve inweba i-stem bonnet ukuqinisekisa ukuthi i-valve isetshenziswa. kusevisi yezinga lokushisa eliphansi kakhulu, izinga lokuvuza kwevalvu linguziro.
- ● Uhlobo lokushisa oluphezulu, izinga lokushisa eliphakathi nendawo liphakeme njengo-540 ℃, umzimba we-valve nezingxenye zangaphakathi zenziwe ngensimbi ekhethekile ye-alloy ekwazi ukumelana nokushisa okuphezulu ngemva kokwelashwa okukhethekile, futhi isiqu se-valve sinwetshwa ngokukhipha ukushisa ukuze kuqinisekiswe ukusetshenziswa okuvamile endaweni ephakeme. isevisi yokushisa, nokusebenza kwe-valve kungukuvuza kwe-zero.
- I-ARAN Metal Metal Seated Ball Valves asetshenziswa kakhulu ezimweni ezinzima zesevisi njengokugqwala okuphezulu noketshezi lwenqubo yokuguguleka enezinhlayiya eziqinile namazinga okushisa aphezulu noma umfutho ophakeme, izimo ezinjalo ivalve yebhola ehlezi ethambile ayikwazanga ukuqina ngenxa yomehluko wezihlalo.Ngesicelo sombuzo, ulwazi lwe-valve medium kanye nezinga lokushisa lubaluleke kakhulu kunjiniyela wezokuthengisa we-QL ukukhetha uhlobo olulungile lwemodeli.
