1. Kugadziriswa kwevhavha yegedhi
1.1 Iwo makuru tekinoroji paramita:
DN: NPS1”~ NPS28”
PN: CL150~CL2500
Zvinhu zvezvikamu zvikuru: ASTM A216 WCB
Dzinde—ASTM A276 410;Chigaro—ASTM A276 410;
Chiso chinosunga—VTION
1.2 Mitemo neMitemo Inoshandisika: API 6A、API 6D
1.3 Chimiro chevhavha (ona Fig.1)
Fig.1 vharafu yegedhi
2. Kuongorora uye kugadzirisa
2.1:Kuongorora kwekunze kwekunze:
Ongorora kunze kwevharuvhu kuti uone kana paine kukuvara, wobva waverengerwa;Nyora rekodhi.
2.2 Ongorora goko uye kuisa chisimbiso:
Tarisa kana paine mamiriro ekuvuza uye ita rekodhi yekuongorora.
3. Disassemble of the Valve
Ivhavha inofanira kuvharwa isati yaparadzana uye kusunungura mabhoti ekubatanidza.Ichasarudza yakakodzera isingachinjiki spanner kune looser mabhaudhi，Nzungu dzichakuvadzwa nyore nyore neinogadziriswa spanner.
Mabhaudhi ane ngura uye nzungu zvinofanira kunyoroveswa neparafini kana mvura inobvisa ngura;Tarisa screw thread direction wobva wamonyorora zvishoma nezvishoma.Zvikamu zvakapatsanurwa zvinofanirwa kuverengerwa, kucherechedzwa uye kuchengetwa zvakarongeka.Stem uye gedhi disc zvinofanirwa kuiswa pabhuraketi kudzivirira Scratch.
3.1 Kuchenesa
Ita shuwa kuti maspare parts acheneswa zvinyoro nyoro nebhurashi neKerosene, peturu, kana mishonga yekuchenesa.
Mushure mekuchenesa, ita shuwa kuti spare parts haina-girisi & ngura.
3.2 Kuongororwa kwezvikamu zvakasara.
Ongorora zvese zvakasara uye nyora rekodhi.
Ita chirongwa chakakodzera chekugadzirisa maererano nechigumisiro chekuongorora.
4. Kugadziriswa kwezvikamu zvakasara
Gadzirisa zvikamu zvakasara zvinoenderana nemhedzisiro yekuongorora uye chirongwa chekugadzirisa;tsiva zvidimbu nezvinhu zvakafanana kana zvichidiwa.
4.1 Kugadziriswa kwegedhi:
① Kugadziriswa kweT-slot: Welding inogona kushandiswa muT-slot fracture kugadzirisa, Yakarurama T-slot kukanganisa, Weld mativi ese ane yekusimbisa bar.Pamusoro welding inogona kushandiswa kugadzirisa T-slot pasi.Nokushandisa kupisa kurapwa mushure mekugadzirisa kuitira kuti ubvise kushushikana uye wobva washandisa PT kupinda kuti uongorore.
②Kugadziridza kwakadonha:
Kudonhedza zvinoreva mukaha kana kutsemuka kwakakomba pakati pechiso chekuvharisa gedhi nechiso chekuisa chisimbiso cheSeat.Kana parallel gedhi vharafu yakadonha, inogona weld kumusoro uye pasi wedge, ipapo, gadzira kugaya.
4.2 Kugadziriswa kwechiso chakasimwa
Chikonzero chikuru chekuvhara mukati mevharuvhu ndiko kuvhara kukuvara kwechiso.Kana kukuvara kwakakomba, inoda weld, machining uye kukuya chisimbiso kumeso.Kana zvisiri serious, kugaya chete.Kukuya ndiyo nzira huru.
a.Nheyo yekutanga yekukuya:
Joinha pamusoro pekukuya chishandiso pamwe chete neworkpiece.Baya jekiseni rinokuvadza mumukana uri pakati penzvimbo, uye wofambisa mudziyo wekukuya kuti ukuye.
b.Kukuya kwechiso chekuvhara gedhi:
Kukuya mode: manual mode kushanda
Smear abrasive pandiro zvakaenzana, isa workpiece pandiro, wozotenderera uchikuya zvakananga kana "8" mutsara.
4.3 Kugadziriswa kwehunde
a.Kana chero kukwenya pachiso chekuvharisa tsinde kana hutsinye husingakwanise kuenderana nedhizaini chiyero, chisimbiso chechiso chinogadziriswa.Kugadzirisa nzira: kukuya sandara, Circular kugaya, Gauze kugaya, muchina kukuya uye Cone kugaya;
b.Kana hunde yevharuvhu yakakotama > 3%, gadzirisa Kutwasanura kurapwa nepakati zvishoma muchina wekukuya kuti uve nechokwadi chekupedza uye kugadzirisa kutsemuka.Kutwasanura nzira: Static pressure kutwasanudza, Kutonhora kutwasanudza uye Kupisa kutwasuka.
c.Kugadzirisa musoro we stem
Musoro wetsinga (stem head) zvinoreva mativi edzinde (stem sphere, stem top, top wedge, connecting trough etc) akabatana nezvikamu zvakavhurika nekuvhara.Kugadzirisa nzira: kucheka, welding, isa mhete, isa plug nezvimwe.
d.Kana isingakwanisi kuzadzisa zvinodiwa zvekuongorora, inofanirwa kugadzira zvakare nezvinhu zvakafanana.
4.4 Kana paine kukuvara nechiso cheflange pamativi ese emuviri, inofanirwa kugadzirisa machining kuti ienderane nezvinodiwa.
4.5 Mativi ese ari maviri emuviri RJ yekubatanidza, kana isingaenderane neyakajairwa zvinodiwa mushure mekugadzirisa, inofanirwa kugadzirwa.
4.6 Kutsiviwa kwezvikamu zvekupfeka
Kupfeka zvikamu zvinosanganisira gasket, kurongedza, O-ring etc. Gadzirira kupfeka zvikamu maererano nezvinodiwa zvekuchengetedza uye ita rekodhi.
5. Unganidza uye kuisa
5.1 Gadziriro: Gadzirira zvakagadziriswa zvakasara, gasket, kurongedza, kuisa maturusi.Isa zvikamu zvose zvakarongeka;usavata pasi.
5.2 Cheki chekuchenesa: Chenesa masipire (chisungo, chisimbiso, dzinde, nzungu, muviri, boneti, joko nezvimwewo) neParafini, peturu kana mumiririri wekuchenesa.Ita shuwa kuti hapana-girisi & ngura.
5.3 Kuiswa:
Pakutanga, tarisa indentation ye stem uye gedhi rekuisa chisimbiso chiso chinosimbisa mamiriro ekubatanidza;
Geza, pukuta muviri, bhoneti, gedhi, chisimbiso kumeso kuti ugare wakachena, Isai masipari muhurongwa uye simbisa mabhaudhi zvine hukasha.
