1. Ukugcinwa kwe-valve yesango
1.1 Imingcele esemqoka yezobuchwepheshe:
I-DN: NPS1 ”~ NPS28”
PN: CL150 ~ CL2500
Izinto zezingxenye eziyinhloko: ASTM A216 WCB
Isiqu — ASTM A276 410; Isihlalo-ASTM A276 410;
Ubuso bokubekwa uphawu-VTION
1.2 Amakhodi Namazinga Asebenzayo: API 6A, API 6D
1.3 Ukwakheka kwe-valve (bona i-Fig. 1)
Umdwebo 1 I-valve yesango
2. Ukuhlolwa kanye nokugcinwa
2.1: Ukuhlolwa kwendawo yangaphandle:
Hlola indawo engaphandle ye-valve ukuze uhlole ukuthi awukho yini umonakalo, bese ufaka izinombolo; Bhala phansi.
2.2 Hlola igobolondo nokufakwa uphawu:
Bheka ukuthi ngabe kunesimo esivuzayo bese wenza irekhodi lokuhlola.
3. Ukuqaqa Valve
Valve kufanele ivalwe ngaphambi ukuqaqa futhi athambise amabhawodi yokuxhuma. Sizokhetha ispanner esifanelekile esingaguquguquki kumabhawodi we-looser, Amantongomane azokonakala kalula nge-spanner eguquguqukayo.
Amabhawodi agqwalile namantongomane kufanele afakwe nge-parafini noma nge-rust remover; Hlola isiqondisi sentambo bese ujija kancane. Izingxenye ezihlanganisiwe kufanele zifakwe izinombolo, zimakwe futhi zigcinwe ngokulandelana. Isiqu nediski yediski kufanele ifakwe kubakaki ukugwema iScratch.
3.1 Ukuhlanza
Qiniseka ukuthi izingxenye eziseceleni zihlanzwa kancane ngokuxubha nge-Kerosene, uphethiloli, noma izinto zokuhlanza.
Ngemuva kokuhlanza, qiniseka ukuthi izingxenye ezisele azinamafutha nokugqwala.
3.2 Ukuhlolwa kwezingxenye ezingasebenzi.
Hlola zonke izingxenye ezisele bese wenza irekhodi.
Yenza uhlelo olufanele lokugcinwa ngokwemiphumela yokuhlola.
4. Ukulungiswa kwezingxenye zokungcebeleka
Lungisa izingxenye ezisele ngokuya komphumela wokuhlola kanye necebo lokulungisa; shintsha izingxenye ezisele ngezinto ezifanayo uma kudingeka.
Ukulungiswa kwesango:
Ukulungiswa kwe-T-slot: Ukushisela kungasetshenziswa ekulungisweni kwe-T-slot fracture, Ukulungiswa kwe-T-slot okulungile, Weld zombili izinhlangothi nge-bar yokuqinisa. Ukushisela okungaphezulu kungasetshenziswa ukulungisa i-T-slot engezansi. Ngokusebenzisa ukwelashwa kokushisa ngemuva kokushisela ukuze uqede ukucindezela bese usebenzisa ukungena kwe-PT ukuhlola.
Ukulungiswa kokulahla:
Ukulahlwa kusho igebe noma ukuhlukaniswa okungathi sína phakathi kobuso bokufakwa uphawu kwesango nobuso bokubekwa kwesihlalo. Uma ukufana kwesango valve kwehlile, kungaba weld phezulu naphezulu nesigaxa ke inqubo inqubo ukugaya.
4.2 Ukulungiswa kobuso bokuvala
Imbangela enkulu yokuvuza kwangaphakathi kwe-valve wukubeka uphawu ukulimala kobuso. Uma umonakalo ubucayi, udinga ukuhlanganisa, ukwenza imishini nokugaya ubuso bokuvala. Uma kungenjalo, kugaya kuphela. Ukugaya kuyindlela eyinhloko.
a. Isisekelo esiyisisekelo sokugaya:
Joyina ubuso bethuluzi lokugaya kanye nocezu lomsebenzi. Jova i-elrasive ibe yigebe phakathi kwendawo, bese uhambisa ithuluzi lokugaya ukugaya.
b. Ukugaya ubuso bokufakwa uphawu kwesango:
Imodi yokugaya: ukusebenza kwemodi yesandla
Smear esigaxeni epuletini ngokulinganayo, beka okokusebenza epuletini, bese ujikeleza ngenkathi ugaya umugqa oqondile noma u- “8”.
4.3 Ukulungiswa kwesiqu
a. Uma noma yikuphi ukuklwebheka ebusweni bokumiswa kwesiqu noma indawo emangelengele kungalingani nobunjiniyela bokuklanywa, ubuso bokuvala buzolungiswa. Izindlela zokulungisa: ukugaya okuyisicaba, ukugaya okuyindilinga, ukugaya kwe-gauze, ukugaya umshini nokugaya isigaxa
b. Uma i-valve stem bent> i-3%, inqubo iqondisa ukwelashwa ngomshini omncane wokugaya ukuze uqiniseke ukuphela kokuphothula nokucubungula ukutholwa kokuqhekeka. Izindlela zokuqondisa: Ukuqondiswa kwengcindezi eqinile straight ukuqondisa amakhaza nokuqondisa ukushisa.
c. Ukulungiswa kwekhanda lesiqu
Ikhanda lesiqu lisho izingxenye zesiqu (isiqu sesiqu, isiqu phezulu, isigaxa saphezulu, umkhombe wokuxhuma njll) exhunywe nezingxenye ezivulekile nezivaliwe. Izindlela zokulungisa: ukusika, ukushisela, ukufaka indandatho, ukufaka ipulagi njll.
d. Uma ingeke ihlangabezane nemfuneko yokuhlola, kufanele iphinde ikhiqize ngezinto ezifanayo.
4.4 Uma kukhona umonakalo ngobuso be-flange ezinhlangothini zombili zomzimba, kufanele icubungule imishini ukufanisa imfuneko ejwayelekile.
4.5 Zombili izinhlangothi zokuxhuma kwe-RJ yomzimba, uma zingakwazi ukufanisa imfuneko ejwayelekile ngemuva kokulungiswa, kufanele ziboshwe
4.6 Ukushintshwa kwezingxenye zokugqoka
Izingxenye zokugqoka zifaka i-gasket, ukupakisha, i-O-ring njll. Lungisa izingxenye zokugqoka ngokuya ngezidingo zesondlo bese wenza irekhodi.
5. Hlanganisa futhi ufake
5.1 Amalungiselelo: Lungisa izingxenye zokulungisa ezilungisiwe, i-gasket, ukupakisha, amathuluzi wokufaka. Hlela zonke izingxenye ngokuhlelekile; ungalali phansi.
5.2 Isheke lokuhlanza: Hlanza izinsimbi (i-fastener, uphawu, isiqu, umuthi, umzimba, ibhonethi, ijoka njll) nge-Kerosene, uphethiloli noma umenzeli wokuhlanza. Qiniseka ukuthi awekho amafutha & ukugqwala.
5.3 Ukufaka:
Ekuqaleni, hlola ukuhlukaniswa kwesiqu nobuso bokufaka isango ukuqinisekisa isimo sokuxhuma;
Sula, sula umzimba, ibhonethi, isango, ukubopha ubuso ukuze uhlale uhlanzekile, Faka izingxenye ezisele ukuze uqinise amabhawodi ngokulingana.
