1. Ukugcinwa kwevalvevu yesango
1.1 Iiparameter zobugcisa eziphambili:
I-DN: NPS1 "~ NPS28"
PN: CL150 ~ CL2500
Izinto zezinto eziphambili: I-ASTM A216 WCB
Isiqu-ASTM A276 410; Isihlalo-ASTM A276 410;
Ukutywina ubuso-VTION
1.2 Iikhowudi kunye neMigangatho esebenzayo: API 6A, API 6D
1.3 Ubume bevalvu (jonga Ikhiwane. 1)
Umzobo 1 Isango ivelufa
2. Ukuhlolwa kunye nokugcinwa
2.1: Ukuhlolwa komphezulu wangaphandle:
Jonga umphandle wevalufa ukujonga ukuba akukho monakalo na, emva koko ubala amanani; Yenza ingxelo.
2.2 Hlola iigobolondo kunye nokutywinwa:
Jonga ukuba ikhona imeko evuzayo kwaye wenze irekhodi lokuhlola.
3. Disassemble yeValve
Valve kufuneka ivalwe phambi kokuba ibattery kunye nokukhulula iibholiti kokuxhuma. Uya kukhetha i-spanner esingalungelelaniswanga efanelekileyo kwiibholiti ezikhululekileyo, Amantongomane aya konakaliswa ngokulula sisipanele
Iibholiti zerusi namandongomane kufuneka zifakwe iparafini okanye irusi esusa ulwelo; Jonga ulwalathiso lwescrew kwaye ujike kancinci. Iindawo ezidityanisiweyo kufuneka zibhalwe iinombolo, ziphawulwe kwaye zigcinwe zilandelelana. Isiqu nediski yedisk kufuneka zibekwe kubakaki ukunqanda ukukrwela.
3.1 Ukucoca
Qinisekisa ukuba iindawo zokugcina izinto zicocwa kakuhle ngebrashi ngepetroli, ipetroli, okanye izixhobo zokucoca.
Emva kokucoca, qiniseka ukuba izinto zokungcebeleka azikho igrisi kunye nomhlwa.
3.2 Ukuhlolwa kweendawo zokugcina izinto.
Hlola zonke iindawo zokugcina uze wenze irekhodi.
Yenza isicwangciso esifanelekileyo sokugcina ngokweziphumo zohlolo.
4. Ukulungiswa kweendawo zokugcina izinto
Lungisa iindawo zokugcina izinto ngokwesiphumo sovavanyo kunye nesicwangciso sokugcina; beka endaweni yezinto zakho xa kufuneka njalo.
Ukulungiswa kwesango:
Ukulungiswa kwe-T-slot: I-Welding inokusetyenziswa kulungiso lwe-T-slot, ukulungiswa kweT-slot echanekileyo, ukuwelda omabini amacala ngokuqinisa ibha. Ukujongana nokuwelda kungasetyenziselwa ukulungisa indawo esezantsi yeT-slot. Ngokusebenzisa unyango lobushushu emva kokuwelda ukuze kupheliswe uxinzelelo kwaye emva koko usebenzise ukungena kwe-PT ukuhlola.
Ukulungiswa kwezinto ezilahliweyo:
Ukulahla kuthetha umsantsa okanye ukusasazeka okukhulu phakathi kwesango lokutywina ubuso kunye nesihlalo sokutywina. Ukuba isango ivelufa esangweni iyehla, unako weld phezulu nesezantsi wedge, ngoko, inkqubo besila.
4.2 Ukulungiswa kobuso bokutywina
Unobangela ophambili wokuvuza kwethambo yangaphakathi kukutywina ukonakala kobuso. Ukuba umonakalo mkhulu, kufuneka ukuwelda, ukurola kunye nokusila ubuso. Ukuba ayisiyongozi, kukusila kuphela. Ukusila yeyona ndlela iphambili.
a. Umgaqo osisiseko wokugaya:
Joyina umphezulu wesixhobo sokusila kunye ne-workpiece. Faka isitofu esirhabaxa phakathi komphezulu, emva koko ususe isixhobo sokugaya.
b. Ukusila kobuso bokutywina isango:
Imowudi yokusila: indlela yokusebenza yesandla
Smear abrasive on the plate evenly, put the workpiece on the plate, and then rotate while grind in straight or “8” line.
4.3 Ukulungiswa kwesiqu
a. Ukuba nakuphi na ukukrwela ebusweni bokutywina isiqu okanye umphezulu omdaka awunakulingana nomgangatho woyilo, ubuso bokutywina buya kulungiswa. Iindlela yokulungisa: ukusila tyaba, Ukusila setyhula, Ukugaya i-gauze, ukugaya umatshini kunye nokugaya kweCone
b. Ukuba isiqu sevalve sigobile> 3%, inkqubo yolula unyango liziko elingaphantsi lokugaya umatshini ukuqinisekisa umphezulu wokugqiba kunye nenkqubo yokufumanisa ukubonwa. Iindlela ezolulekileyo: Ukulungisa uxinzelelo lwe-Static, ukolula okubandayo kunye nokulungisa ubushushu.
c. Ukulungiswa kwentloko yesinti
Isiqu sentloko sithetha iindawo ezithile zesiqu (isiqu somda, umphezulu wesiqu, isinqumka esingentla, umgubo wokudibanisa njlnjl) onxulunyaniswe neendawo ezivulekileyo nezisondeleyo. Iindlela zokulungisa: ukusika, ukuwelda, ukufaka isangqa, ukufaka iplagi njl.
d. Ukuba awukwazi ukuhlangabezana neemfuno zohlolo, kufuneka uphinde uvelise ngezinto ezifanayo.
4.4 Ukuba kukho nawuphi na umonakalo ebusweni be-flange kumacala omabini omzimba, kufuneka uqhubekeke ngomatshini ukuze uhambelane nemfuno esemgangathweni.
4.5 Omabini amacala oqhagamshelo lwe-RJ lomzimba, ukuba awunakulingana nemfuneko esemgangathweni emva kokulungiswa, kufuneka adityaniswe.
4.6 Ukutshintshwa kweenxalenye zokunxiba
Izinto zokunxiba zibandakanya i-gasket, ukupakisha, i-O-ring njlnjl. Lungisa iinxalenye zokunxiba ngokweemfuno zolondolozo kwaye wenze irekhodi.
5. Hlanganisa kunye nokufakela
5.1 Amalungiselelo: Lungisa indawo yokulungisa elungisiweyo, igasket, ukupakisha, izixhobo zokufaka. Beka zonke iindawo ngokulandelelana kwazo; sukulala phantsi.
5.2 Ukucoca itshekhi: Ukucoca iindawo zokucoca (ukuqinisa, ukutywina, isiqu, umthi, umzimba, ibhonethi, idyokhwe njlnjl) ngeParafini, ipetroli okanye iarhente yokucoca. Qinisekisa ukuba akukho-grease kunye ne-rust.
5.3 Ufakelo:
Ekuqaleni, jonga ukubekwa kwesiqu kunye nesango lokutywina ubuso buqinisekisa imeko yokudibanisa;
Ukucoca, sula umzimba, ibhonethi, isango, ukutywina ubuso ukuze uhlale ucocekile, Fakela izixhobo ezizezinye ngolungelelwano kwaye uqinise iibholiti ngokulinganayo.
