Insimbi ephothiwei-valve yebhola ye-flange, uphawu lufakwe esihlalweni sensimbi engagqwali, kanti isihlalo sensimbi sifakwe isiphethu ekugcineni kwesihlalo sensimbi. Lapho indawo yokuvala igugile noma ishisiwe, isihlalo sensimbi kanye nebhola kucindezelwa ngaphansi kwesenzo sesiphethu, futhi uphawu lwensimbi lunomsebenzi ohlukile wokukhulula ingcindezi othomathikhi. Lapho ingcindezi ephakathi emgodini we-valve idlula amandla okulayisha kusengaphambili esiphethu, isihlalo esiseceleni sokuphuma siyakhishwa ebholeni ukuze kufezwe umphumela wokukhulula ingcindezi othomathikhi, futhi isihlalo sibuya ngokuzenzakalelayo ngemva kokukhululeka kwengcindezi. Kufanelekela amanzi, izinyibilikisi, ama-asidi, igesi yemvelo kanye nezinye izinto zokusebenza ezisetshenziswa kakhulu, kodwa futhi zifanele i-oxygen, i-hydrogen peroxide, i-methane, i-ethylene kanye nezinye izimo zokusebenza ezimbi ze-medium, kuzo zonke izindlela zokuphila kube isicelo esihle, bese kuthi okulandelayo kuqondwe ukwakheka kwensimbi ye-Tianjin cast.i-valve yebhola ye-flange!
Izici zesakhiwo se-flange yebhola ye-cast steel:
1. Isakhiwo sokuvala isihlalo esiyingqayizivele
Isihlalo se-valve yebhola elangeniwe ngensimbi ecijile sinomklamo wesivalo sangaphambili, esinesivalo esinezindlela ezimbili kanye nomsebenzi wokukhulula ingcindezi ozenzakalelayo ekamelweni eliphakathi. Ibhulakhethi yesivalo elifakwe izinto zokuvala liyantanta futhi lisetshenziswa yisipilingi. Esimweni esivaliwe, indawo yokuvala ihlala isondelene nebhola ukuqinisekisa ukuthi ivalve yakha isivalo sokuvuza lapho ingcindezi iphakeme futhi iphansi.
2, isakhiwo sokukhululeka kwengcindezi okuzenzakalelayo
Uma ingcindezi yegumbi eliphakathi ikhuphuka ngendlela engavamile, ivalvu yebhola yesakhiwo esisodwa inomsebenzi wokukhulula ingcindezi ngokuzenzakalelayo, kanti ivalvu yebhola yesakhiwo esiphindwe kabili isuswa yidivayisi yokukhulula ingcindezi emzimbeni wevalvu.
3, umsebenzi wosizo lokuqala ovaliwe
Idizayini ye-flanged ball valve yensimbi ehlanganisiwe i-AIDS uhlelo lokuvala isihlalo oluphuthumayo. Uma indawo yokuvala yonakele, i-sealant ehambisanayo ifakwa ngohlelo lokuvala olusizayo ukuze kusizwe usizo lokuqala, kanti uhlelo olusizayo lungahlanza futhi lugcobe indawo yesihlalo se-valve uma kudingeka.
4, idivayisi yokulwa nokuqina
Uma kusetshenziswa ivalvu, kuzokhiqizwa ugesi ongaguquki ngenxa yokungqubuzana phakathi kwesihlalo sebhola, okuzoqongelela kukholamu yebhola, ukuze kuvinjelwe ukukhiqizwa kwezinhlansi ze-electrostatic, ikakhulukazi idivayisi yokulwa ne-static ebekwe kuvalvu ukuze ithumele ugesi ongaguquki okhiqizwe.
5. Isakhiwo esingashisi
Isihlalo sevalvu yebhola egxilile yenkampani samukela isakhiwo esiyingqayizivele. Uma kwenzeka umlilo, lapho izinto zokuvala ezingezona ezensimbi zishiswa, indandatho yensimbi isunduza isihlalo ukuze sivalwe kahle ngebhola ngaphansi kwesenzo samandla esiphethu, okuvimbela ukusabalala komlilo nokuchichima kwemidiya.
6. Isakhiwo sobubanzi obugcwele kanye nesakhiwo sobubanzi obuncishisiwe
Ukuze kuhlangatshezwane nezidingo zamakhasimende, i-flange yensimbi ecijile ye-ball valve inochungechunge oluphelele lobubanzi kanye nochungechunge oluncishisiwe lobubanzi. Ububanzi besilinda se-ball valve oluphelele lobubanzi buhambisana nobubanzi besilinda, okulula ukuyihlanza. I-ball valve encishisiwe isisindo esincane, iyingxenye yokumelana koketshezi kwe-globe valve efanayo ye-caliber, amathuba abanzi.
I-valve yebhola ye-flange yensimbi ehlanganisiwe itholakala ku-oyela, igesi yemvelo, ukumba amalahle ne-ore, ukucwenga nokucubungula kanye nohlelo lokuthuthwa kwamapayipi lwemikhiqizo yamakhemikhali, imithi, ukukhiqizwa kokudla; Amandla kagesi, amandla okushisa kanye nezinhlelo zokukhiqiza amandla enuzi ohlelweni lokuhlinzeka ngamanzi kanye nokuthuthwa kwamanzi, ukushisa kanye nokuhlinzeka ngegesi lwamabhizinisi asemadolobheni nasezimbonini; Ohlelweni lokuthuthwa kwamanzi kanye nokunisela epulazini, uhlelo lokukhipha igolide luye lwasetshenziswa kabanzi, okuwumkhiqizo obalulekile wemishini ohlobene nokwakhiwa kokukhiqiza, ukwakhiwa kokuvikela izwe kanye nokuphila kwabantu. Ama-valve ebhola e-flange yensimbi ehlanganisiwe ye-Tianjin avalwe ezinhlelweni ezahlukene zamapayipi ukuze anqume noma afake ukugeleza kwemidiya, futhi athuthe imidiya endaweni ngayinye ngokuhambisana nezinyathelo ezigciniwe.
