Grinding ubedo yore ma pol kare jutiyo kudu pi thum pa valve i kare mi yubu piny. Grinding copo ketho valve sealing surface nwangu rwom ma malu, geometric shape roughness man surface roughness, ento ecopu ngo medo ber pa mutual position accuracy ikind thenge mi sealing surface. Ber pa rwom pa ground valve sealing surface ubedo 0.001~0.003mm; ber pa kit piny (macalu bedo marom) utiye 0.001mm; rwom pa wi ngom utiye 0.1~0.008.
Lembe ma pire tek mi ketho piny iwi ngom uketho i iye lembe abic: yore mi poko piny, wotho mi poko piny, ngwec mi ngwec, tego pa ngwec man rwom mi ngwec.
1. Yore mi poko
Jam tic mi poko piny man wi ring mi sealing gibedo karacelu maber, man jam tic mi poko piny timo tic mi poko piny ma tek iwi thenge mi joint. Abrasives juketho ikind jam tic mi lapping ku wi ring mi sealing. Ka jam tic mi lapping man wi ring mi sealing giwotho ikumgi gigi, dul pa abrasive grains ma ni i abrasive ne bi ngwec nyo bi ngwec ikind jam tic mi lapping ku wi ring mi sealing. dul pa cuma. Wi got ma iwi wi ring ma jukubo kudu juyike, man i ngeye juyubu geometry ma mitere moth moth.
Gwoko piny epe kende kende tic pa jamb tiyo ku cuma, ento bende tic pa kemikol. Moo ma ni i abrasive copo ketho oxide film iwi piny ma jubi tiyo kudu, man eketho tic mi poko piny doko nyathotho.
2 . wotho mi nyai
Ka jam tic mi poko piny man wi ring mi cing giwotho malube ku juwothgi, wel pa yore mi ngwec pa kabedo acel acel iwi wi cing cing mi cing cing ucikere ni bedu marom. Bende, yo ma rwom pa ngwec ucikere ni bedo ka loke kare ku kare. Lokruok ma nja pa yo ma juwotho kudu juku ng'atu acel acel ma nyai kud udok kendo iwi ng'et ring'o ma juketho i iye, kara kud ekel lanyuth ma nen kamaleng' man umed goro pa ring'o ma juketho i iye. Mi medo, aloka loka ma nja pa yore mi wotho copo ketho ngo abrasive ubed marom, kara cuma ma ni iwi sealing ring ubed maber.
Kadi bende tic mi poko piny ubedo tek man yore mi ngwec lokore lee, tic mi poko piny timore kare ku kare i thenge mi jam tic mi poko piny man thenge mi ring mi ketho piny. Kadi bed ni etiye tic mi cing nyo tic ku cuma, kite ma rwom pa dul ma jukubo kudu ucungo iwi kite ma piny ma jutiyo kudu pi tiyo kudu man kite ma tic kudu.
3. ngweje
Ka ngwec pa grinding ubedo pio pio, grinding ne bedo maber. Kite mi poko piny ubedo nyap, jamb tedu madwong ukadhu kud i wi piny ma jutiyo kudu pi kare acel acel, man cuma madwong jupoko.
Ngweje mi nyai ubedo 10~240m/min. Pi piny ma jutiyo kudu ma mitu rwom ma malo mi tiyo kudu, ngwec pa tic eca kadhu ngo 30m/min. Kite ma juyiko kudo valve utiye ku winjiri ku piny ma juyiko kudo. Kite ma juyubu ko copper ku cast iron ubedo 10~45m/min; kabedo mi mako cuma ma tek man cuma ma tek utiye 25~80m/min; kabedo ma juketho i iye austenitic stainless steel 10~25m/min.
4. tego mi nyayo
Ber pa tic mi poko piny medre ku mediri pa kero mi poko piny, man kero mi tiyo kudu umitu kud obed malo akeca, pol kare 0.01-0.4MPa.
Ka jube tiyo ku cuma, copper man austenitic stainless steel, kero mi juku ubedo 0.1~0.3MPa; kabedo ma juketho i iye steel ma tek man alloy ma tek utiye 0.15~0.4MPa. Kwan wel madit pi tic ma tek man wel ma nok pi tiyo maber.
5. Miye mi poko piny
Calu ma nyayo piny ubedo tic mi thum, wel mi poko piny utiye nok. Dit pa grinding allowance ucungo iwi kite ma jutiyo kudu maber man kite ma piny ne ucungo kudu. I the cik mi neno ni juwodho lembe ma jutimo con man yiko peko mi geometric mi sealing ring, ka grinding allowance nok, ber.
Kabedo ma juketho i iye piny ucikere ni jwigo maber mapodi juyike ngo. I ngei nyayo maber, kabedo ma juketho i iye copo bedu maber, man jamb tiyo ma nok utiye: diameter ma romo 0.008~0.020mm; rwom pa ndege utiye 0.006~0.015mm. Kwan wel ma nok ka tic ku cing nyo tek pa piny utiye malo, man kwany wel madit ka tic ku cing nyo tek pa piny utiye piny.
Kabedo ma juketho i iye valve utiye marac ni tiyo kudu, pi meno jucopo tiyo ku fine turning. I ngei thum pa loko, kabedo ma juketho i iye umitu obed ngom ma nyap mapodi judaru ngo, man rwom pa ndege ubedo 0.012~0.050mm.
Tianjin tanggu water-seal valve Co.,ltd ubedo ku tic ma pire tek mi yubuvalve pa butterfly ma bedo maber, valve mi dhugola, Y-strainer, valve mi rwom, wafer check valve, ni medo mukende.
