1. Ukugcinwa kwe-valve yesango
1.1 Imingcele yezobuchwepheshe eyinhloko:
I-DN:NPS1”~ NPS28”
I-PN: CL150~CL2500
Impahla yezingxenye eziyinhloko: ASTM A216 WCB
Isiqu—ASTM A276 410; Isihlalo—ASTM A276 410;
Ubuso obuvaliwe—VTION
1.2 Amakhodi Asebenzayo Namazinga: API 6A、API 6D
1.3 Isakhiwo se-valve (bona u-Fig.1)
Fig.1 Ivalve yesango
2. Ukuhlola kanye nokugcinwa
2.1:Ukuhlolwa kwendawo engaphandle:
Hlola ingaphandle levalvu ukuze uhlole ukuthi ukhona yini umonakalo, bese ufaka izinombolo; Yenza irekhodi.
2.2 Hlola igobolondo nokuvala:
Bheka ukuthi ngabe sikhona yini isimo sokuvuza bese wenza irekhodi lokuhlola.
3. Ukuhlakazwa kweValve
I-valve kufanele ivalwe ngaphambi kokuhlakazwa futhi ikhulule amabhawodi axhumayo. Kufanele ukhethe isipana esifanele esingalungiseki kumabhawudi axegayo，Amantongomane azolimala kalula ngesipana esilungisekayo.
Amabhawodi agqwalile namantongomane kufanele afakwe uphalafini noma isikhiphi sokugqwala esiwuketshezi; Hlola isiqondiso sentambo yesikulufu bese usonta kancane. Izingxenye ezihlakaziwe kufanele zifakwe izinombolo, zimakwe futhi zigcinwe ngokulandelana. I-stem ne-gate disc kumele ifakwe kubakaki ukuze kugwenywe i-Scratch.
3.1 Ukuhlanza
Qiniseka ukuthi izingxenye eziyisipele zihlanzwa kancane ngebhulashi nge-Kerosene, uphethiloli, noma izinto zokuhlanza.
Ngemuva kokuhlanza, qiniseka ukuthi izingxenye ezisele azinawo amafutha nokugqwala.
3.2 Ukuhlolwa kwezingxenye ezisele.
Hlola zonke izingxenye ezisele bese ubhala irekhodi.
Yenza uhlelo olufanele lokulungisa ngokuhambisana nomphumela wokuhlolwa.
4. Ukulungiswa kwezingxenye ezisele
Lungisa izingxenye ezisele ngokomphumela wokuhlolwa kanye nohlelo lokulungisa; buyisela izingxenye ezisele ngezinto ezifanayo uma kudingeka.
4.1 Ukulungiswa kwesango:
① Ukulungiswa kwe-T-slot: I-Welding ingasetshenziswa ekulungiseni ukuphuka kwe-T-slot, ukuhlanekezela okulungile kwe-T-slot, Weld izinhlangothi zombili nge-reinforcing bar. Ukushisela okungaphezulu kungasetshenziswa ukulungisa i-T-slot phansi. Ngokusebenzisa ukwelashwa okushisa ngemva kokushisela ukuze kuqedwe ukucindezeleka bese usebenzisa ukungena kwe-PT ukuhlola.
②Ukulungiswa kokuwa:
Ukwehliswa kusho igebe noma ukuhlukaniswa okukhulu phakathi kobuso bokuvala isango nobuso bokuvalwa kwesihlalo. Uma i-valve yesango elihambisanayo yehla, ingashisela phezulu nangaphansi, bese, inqubo yokugaya.
4.2 Ukulungiswa kobuso obuvaliwe
Isizathu esiyinhloko sokuvuza kwangaphakathi kwe-valve ukuvala ukulimala kobuso. Uma umonakalo unzima, kudingeka ukushisela, machining futhi ugaye sealing ubuso. Uma kungenjalo, ukugaya kuphela. Ukugaya kuyindlela eyinhloko.
a. Umgomo oyisisekelo wokugaya:
Joyina ubuso bethuluzi lokugaya kanye ne-workpiece. Faka i-abrasive esikhaleni phakathi kwezindawo, bese uhambisa ithuluzi lokugaya ukuze ligaye.
b. Ukugaya kobuso bokuvalwa kwesango:
Imodi yokugaya: ukusebenza kwemodi yezandla
Gcoba i-abrasive epuletini ngokulinganayo, beka ucezu lokusebenza epuletini, bese uphendukisa ngenkathi ugaya umugqa oqondile noma "8".
4.3 Ukulungiswa kwesiqu
a. Uma noma yikuphi ukuklwebheka ebusweni obuvalekile esiqwini noma endaweni emagebhugebhu kungakwazi ukufana nendinganiso yedizayini, ubuso bokuvala kufanele bulungiswe. Izindlela zokulungisa: ukugaya okuyisicaba, ukugaya okuyisiyingi, ukugaya i-Gauze, ukugaya umshini kanye nokugaya i-Cone;
b. Uma isiqu se-valve sigobile >3%, qhuba ukwelashwa kokuqondisa ngomshini wokugaya omncane ukuze uqiniseke ukuthi uphelile futhi ucubungula ukutholwa kokuqhekeka. Izindlela zokuqondisa: Ukuqondisa okuqinile, Ukuqondisa okubandayo kanye nokuqondisa ukushisa.
c. Ukulungiswa kwekhanda lesiqu
Ikhanda lesiqu lisho izingxenye zesiqu (i-sphere ye-stem, i-stem top, i-wedge ephezulu, i-trough yokuxhuma njll) ezixhunywe nezingxenye ezivulekile nezivaliwe. Izindlela zokulungisa: ukusika, ukushisela, ukufaka indandatho, ukufaka ipulaki njll.
d. Uma ingakwazi ukuhlangabezana nemfuneko yokuhlola, kufanele ikhiqize kabusha ngezinto ezifanayo.
4.4 Uma kukhona umonakalo ongaphezulu kwe-flange ezinhlangothini zombili zomzimba, kufanele kucutshungulwe ukucutshungulwa ukuze kufane nemfuneko evamile.
4.5 Zombili izinhlangothi zokuxhuma kwe-RJ yomzimba, uma zingakwazi ukuhambisana nezidingo ezijwayelekile ngemva kokulungiswa, kufanele zishiselwe.
4.6 Ukushintshwa kwezinsimbi zokugqoka
Izingxenye zokugqoka zihlanganisa i-gasket, ukupakisha, i-O-ring njll. Lungiselela izingxenye zokugqoka ngokuvumelana nezidingo zesondlo futhi wenze irekhodi.
5. Hlanganisa futhi ufake
5.1 Amalungiselelo: Lungiselela izingxenye ezisele ezilungisiwe, i-gasket, ukupakisha, amathuluzi okufaka. Beka zonke izingxenye ngokulandelana; ungalali phansi.
5.2 Isheke lokuhlanza: Hlanza izingxenye eziyisipele (isibambiso, ukuvala, isiqu, amantongomane, umzimba, ibhonethi, ijoka njll) nge-Kerosene, uphethiloli noma i-ejenti yokuhlanza. Qinisekisa ukuthi akukho grease nokugqwala.
5.3 Ukufakwa:
Ekuqaleni, hlola i-indent ye-stem kanye nobuso bokuvalwa kwesango qinisekisa isimo sokuxhuma;
Hlanza, sula umzimba, ibhonethi, isango, ubuso obuvale ukuze buhlale buhlanzekile, Faka izingxenye eziyisipele ngokulandelana futhi uqinise amabhawodi ngokulinganayo.
