Valve sealing surface grinding and assembly Valve mubato uye handwheel pendi tsanangudzo

Iyo yekupedzisa kugadzirisa nzira, inogona kuita kuti zvikamu zviwane yakakwira dimensional kurongeka, geometric chaiyo uye kupedzisa kwepamusoro, asi haigone kuvandudza nzvimbo yepakati pakati peiyo yechokwadi. Chishandiso chekukuya chinofanirwa kusangana nezviviri zvinotevera: ① zviri nyore kunyudza mabrasive particles ② inogona kuchengetedza iyo geometric chaiyo yechishandiso chekukuya kwenguva yakareba. Naizvozvo, iyo yakajairika kushandiswa kwezvinhu zvakapfava pane iyo workpiece kuita maturusi ekutsvagisa, anowanzo shandiswa grey cast iron. Mukuita kwekusangana kwevharuvhu, muviri wevharuvhu unowanzo shandiswa sezvikamu zvereferenzi, zvinoenderana nehurongwa hwakatsanangurwa mukuita kwegungano, uye nzira inoitwa. Pamberi peungano, zvakakosha kutarisa kana zvikamu zvakabviswa uye zvakacheneswa.
Valve sealing surface grinding
Kutanga, kukuya misimboti nemidziyo
(I) Basic Principles:
Iyo yekupedzisa kugadzirisa nzira, inogona kuita kuti zvikamu zviwane yakakwira dimensional kurongeka, geometric chaiyo uye kupedzisa kwepamusoro, asi haigone kuvandudza nzvimbo yepakati pakati peiyo yechokwadi.
Kukuya, turusi uye workpiece yepamusoro inoenderana pamwe chete, iyo yepakati yekuzadza mabrasives, kana chishandiso chiri padyo nenzvimbo yakabatana, yakaoma kurovedza muviri pakati pezvikamu zviviri zveabrasive grits pamusoro inotsvedza kana kukunguruka, chikamu cheabrasive chakamisikidzwa kana sessile mumudziyo wekushandisa, uye akagurwa ne workpiece pemvura iri nhete chaizvo akaturikidzana simbi, convex peak pamusoro workpiece iri kutanga achikuya, zvishoma nezvishoma kuwana chakanakira pamusoro chinodiwa.
Kuti uite yunifomu yekukuya pamusoro, nzira yekufamba yeimwe neimwe poindi pane yekushanda kune mudziyo wekukuya inofanira kunge yakafanana nekure sezvinobvira, saka kutungamira kwekufamba kunofanirwa kuchinjwa nguva dzose.
Iyo inokurumidza kufambisa kufamba, iyo yakakwirira yekubudirira, asi kana yakanyanyisa, ichaita kuti workpiece inopisa uye inokanganisa geometric yakarurama. Panguva imwecheteyo, tinofanira kuchenjerera kuti tisanyanya kudzvinyirira pamusoro pepamusoro, kana zvisina kudaro zvichakonzerawo kupisa.
Nekuti kugaya kuri kutsetseka kugadzirisa, iyo yekucheka huwandu idiki kwazvo, saka mukati inogona kuve nechokwadi chekubvisa iyo yekugadzirisa trace yekupedzisira maitiro, iyo yekutanga kugadzirisa iyo workpiece geometry kukanganisa, idiki iyo yekugaya mvumo, zviri nani.
(2) Maturusi ekukuya
Chishandiso chekukuya chinofanirwa kusangana nezviviri zvinotevera: ① zviri nyore kunyudza mabrasive particles ② inogona kuchengetedza iyo geometric chaiyo yechishandiso chekukuya kwenguva yakareba. Naizvozvo, iyo yakajairika kushandiswa kwezvinhu zvakapfava pane iyo workpiece kuita maturusi ekutsvagisa, anowanzo shandiswa grey cast iron.
Abrasive musanganiswa wezvinhu uye abrasive fluid. Zvishandiso zvinowanzoshandiswa zvinoti corundum (alumina), silicon carbide, boron carbide, chromium oxide, iron oxide uye diamond powder, coarse coarse abrasive kana ikashandiswa.
Mvura yekukuya inoshandiswa kugadzirisa abrasive, uye inoita basa rekuzora, kutonhora uye oxidation.
Chepiri, vharafu sealing pamusoro pekukuya
(a) kukuya nemaoko
Manual grinding iri nyore, asi yakaderera kushanda, yakashata, yakakodzera kumabhizimisi maduku uye kugadzirisa.
1. Manual kugaya kwechisimbiso pamusoro pemuviri wevharuvhu
Kushandiswa kweskweya gomba rebindu disc shaped grinding tool inoiswa pachisimbiso pamusoro pevhavha yemuviri mhango, uye ipapo mubato wakareba une musoro wekona unoshandiswa kutyaira ndiro yekukuya yekukuya. Pane gadheni column boss kana kukonzera kupisa conduction plate pagayira kudzivirira mudziyo wekukuya kuti usavhure chisimbiso.
Usati wakuya, mudziyo wekukuya unofanirwa kucheneswa, wakaputirwa neabrasive, uye mudziyo wekukuya unofanirwa kuiswa panzvimbo yekuisa chisimbiso, tanga watendeutsa wachi 180 ° wozoita counterclockwise 90 °, saka wodzokororwa, teerera kune yunifomu uye simba rakakodzera. paunenge uchikuya, uye nguva dzose uwedzere kushungurudza.
2, vharafu ndiro, vharafu disc uye zvimwe zvikamu zvekuisa chisimbiso pamusoro pekukuya
Uchishandisa mundiro yekukuya yekukuya nemanyorero, kutanga pandiro yakaenzana yakavharwa neyakagadzika yekukuya, iyo workpiece inonamirwa kune ndiro, kune rimwe divi kuita kutenderera uye kuita linear kufamba kana nhamba 8 kufamba.
Iyo PAINT ruvara rwevhavha mubato uye vhiri reruoko inosiyana zvichienderana nekuvharisa pamusoro pezvinhu.
