Ivalve yebhola yeflange eneendlela ezintathu

Umgaqo wokuSebenza

Umgaqo-siseko wokusebenza womzi-mveliso weShenchi wevalve yebhola yeflange eneendlela ezintathu ekwaziyo ukumelana nomhlwa isekelwe kwiitshaneli ezimilise okwe-L okanye ezimilise okwe-T ezisikwe ebholeni. Ibhola ibekwe kumbindi womzimba wevalvu kwaye ijikelezwe ngesiphatho. Xa ibhola ijikeleza, amajelo alungelelaniswa okanye alungelelanise ukusuka kumazibuko eevalve ezahlukeneyo, eqonda ukutshintsha, ukudibanisa, okanye ukwahlula isalathiso sokuhamba okuphakathi.

Ibhola enobume be-L:

 Ukujikeleza i-90 ° ivumela i-medium ukuba itshintshe ukusuka kwi-inlet ukuya kuyo nayiphi na i-outlet, ilungele ukuguqulwa kweemeko kunye ne-inlet enye kunye ne-inlet ezimbini okanye ezimbini kunye ne-outlet enye, njengokubonelela ngokutshintshileyo ulwelo kwii-reactors ezimbini.

Ibhola emile okwe-T: 

Ukujikeleza i-180 ° ivumela ukuba onke amazibuko amathathu adityaniswe ngaxeshanye okanye nawaphi na amazibuko amabini adityaniswe, alungele ukuxuba imidiya emibini kwaye emva koko akhuphe (ukudibanisa), okanye ukwahlula imidiya enye kwiziphumo ezimbini (ukwahlula), njenge-air conditioning eshushu kunye neenkqubo zokuxuba amanzi abandayo.

Izinto eziluncedo kuQhagamshelwano lweFlange:

Iivalvu zebhola ezi-3 ze-Shenchi zisebenzisa imidibaniso ye-flange. Xa kuthelekiswa nokudityaniswa kwemisonto, ukudityaniswa kwe-flange kunika ukuxhathisa uxinzelelo oluphezulu; Ukulinganisa kwe-PN16 kunokumelana ngokuzinzileyo noxinzelelo lwe-1.6MPa. I-Disassembly ikulungele, iququzelela ukuhlolwa kunye nokugcinwa rhoqo kwemibhobho. Ukutywinwa okuthembekileyo kuqinisekiswa; i-gasket ye-flange kunye neebholithi zisebenza kunye ukuphelisa umngcipheko wokuvuza. Ifanelekile kwimibhobho yobubanzi obukhulu; kwi-diameters ezingaphezulu kwe-DN50, apho uxhulumaniso lwemisonto lunzima, ii-flanges lukhetho oluqhelekileyo. I-Shenchi, umenzi wevalve yebhola ye-3 ye-3 ye-flanged, inikezela ngeeflange ezihambelana ne-ANSI, i-BS, i-DIN, kunye nemigangatho ye-JIS, ukuhlangabezana neemfuno zabathengi behlabathi.

Ukufakela iNqaku eliPhambili 1:Ulungelelwaniso lweFlange

Ukulungelelaniswa kweFlange Xa ufaka i-valve yebhola ye-Shenchi yeendlela ezintathu ze-flange, ubuso be-flange kufuneka bulungelelaniswe. Iiflange ezimbini kufuneka zihambelane kwaye zigxininise, kunye nokuphambuka okungadluli kuluhlu oluvumelekileyo lwe-gasket ye-flange. Ukunyanzelisa ukulungelelaniswa kwebholithi kuya kubangela ukuguqulwa komzimba wevalve, kuchaphazela ukujikeleza kwebhola kunye nokusebenza kokutywinwa. Emva kokulungelelaniswa, i-gasket kufuneka ifakwe phakathi kwaye ayifanele ikhutshwe. Ivalve yebhola yeflange enexabiso eliphantsi eneendlela ezintathu ayilingani nomgangatho ophantsi; Iimveliso zeShenchi zinika ukuchaneka okuphezulu kunye nokufakwa lula. Iivalvu zebhola ze-flange ezikwazi ukumelana nokutyiwa kweendlela ezintathu ezinemiphetho enomphezulu we-flange ehlangabezana nemigangatho, eqinisekisa ukutywinwa okuthembeke ngakumbi.

Indawo yokuFakela iSibini: UkuQiniswa kweBolt

Iibholithi zeflange kufuneka ziqiniswe ngokwe-diagonally ngokwezigaba. Faka i-torque ngokuthe ngcembe kwizigaba ezi-2-3, ngokulandela ulandelelwano lwe-diagonal ye-180 °. Musa ukuqinisa icala elinye ngexesha elinye, ngaphandle koko uxinzelelo olungalinganiyo kwi-gasket luya kudala iziteshi zokuvuza. Itorque yebholt kufuneka ihambelane namaxabiso asemgangathweni; ukuqina okugqithisileyo kuya konakalisa i-flange okanye iibholiti, ngelixa ukuqina ngaphantsi kuya kubangela ukutywinwa okungonelanga. I-Shenchi 3-indlela ye-flange ye-valve ye-valve ye-factory ibonelela ngetafile ekhuthazwayo ye-torque ukuze abafakeli babhekiselele kuyo. Ezi ndawo zofakelo zibalulekile ekuqinisekiseni ukusebenza kwevalvu yexesha elide engavuziyo; nceda ulandele ngokungqongqo iinkcukacha.

Indawo yokuFakela i-3: Inkxaso yoMbhobho kunye nokuCoca

Ngaphambi kofakelo, ingaphakathi lombhobho kufuneka licocwe ukususa i-welding slag, iifayili zentsimbi, isanti kunye nobunye ukungcola. Izinto zangaphandle ezingena kumngxunya wevalve zinokukrwela ibhola okanye izitywina, ezikhokelela ekuvuzeni. Umbhobho kufuneka uxhaswe ngokuzimeleyo; isivalo akufuneki sithwale ubunzima bombhobho. Iivalvu zebhola ze-tee flange ezinkulu zinzima; ukuthotywa kombhobho kunokutsala iflenge embindini, yonakalise itywina. Iivalvu zebhola ze-tee flange ezinganyangekiyo zenziwe nge-WCB, SUS304, okanye izixhobo ze-SUS316L, ezinobhedu okanye isiseko sevalve yentsimbi. Emva kokugqiba amanqaku okufakela, isibambo kufuneka sijikeleze ngokukhululekileyo ngaphandle kwe-jamming; Ivalve sele ilungele ukusetyenziswa.
