Say panaggiling et kaslakan ya uusaren a paraan na panag-seal ed tapew na saray balbula legan na proseso na panaggawa. Say panaggiling et makagamor na atagey ya sukat na sukat na balbula, geometric shape roughness tan surface roughness, balet agto napaaligwas so mutual position accuracy na saray tapew na sealing surface. Say inkasusto na sukat na ground valve sealing surface et kaslakan ya 0.001~0.003mm; say geometric shape accuracy (singa say ag-inkaparpareho) et 0.001mm; say inkagaspang na tapew et 0.1~0.008.
Say manunan prinsipyo na panag-seal surface grinding et walaan na limaran aspekto: proseso na panaggiling, galaw na panaggiling, kapeles na panaggiling, presyon na panaggiling tan allowance na panaggiling.
1. Proseso na panaggiling
Say panaggiling tan say tapew na sealing ring et maong ya nankakasakey, tan say panaggiling et manggagawa na komplikadon galaw na panaggiling ed tapew na joint. Saray abrasive et iiyan ed baetan na lapping tool tan say tapew na sealing ring. No say lapping tool tan say tapew na sealing ring et onkikiwas ya relatibo ed balang sakey, say kabiangan na saray abrasive grains ed abrasive et onkurong odino onkurong ed baetan na lapping tool tan say tapew na sealing ring. layer na metal. Saray toktok ed tapew na sealing ring et unaan ya i-ground, insan kalkalnan nadampot so nakaukolan ya geometry.
Say panaggiling et aliwan mekanikal labat ya proseso na saray abrasive ed metal, no ag ingen sakey met ya kemikal ya aksion. Say grasa ed abrasive et nayarin manporma na oxide film ed tapew ya iproseso, kanian napapeles so proseso na panaggiling.
2 . galaw na panaggiling
No say grinding tool tan say tapew na sealing ring et onkiwas ya relatibo ed balang sakey, say dagup na saray relatibon sliding paths na kada punto ed tapew na sealing ring ya anggad grinding tool et nepeg ya pareho. Ontan met, say direksion na relatibon galaw et nepeg ya naynay ya manguuman. Say pirmin panguman na direksion na galaw et mangaamper ed kada abrasive grain ya manguulit ed dilin trajectory to ed tapew na sealing ring, pian ag-onlesa so mapatnag iran marka na panag-usar tan ondarakel so inka-magaspang na tapew na sealing ring. Niarum ni, say tuloytuloy ya panguman na direksion na galaw et agto nagawaan ya mas parepareho so pangibunog ed abrasive, kanian say metal ed tapew na sealing ring et mas parepareho so pakaputot to.
Anggaman komplikado so panaggiling tan manguuman a maong so direksion na panaggiling, say panaggiling et naynay ya nagagawa ed tapew na panag-ipit na kagawaan tan say tapew na sealing ring. Balanglan manual o mekanikal ya panaggiling, say geometric shape accuracy na sealing ring surface et manunan naapektoan na geometric shape accuracy na grinding tool tan say grinding movement.
3. kapeles na panaggiling
No mas maples so panaggiling, mas epektibo so panaggiling. Maples so panaggiling, mas dakel ya abrasive particles so ondalan ed tapew na workpiece kada unit time, tan mas dakel ya metal so naputer.
Say kapeles na panaggiling et kaslakan ya 10~240m/min. Parad saray workpiece ya mankaukolan na atagey ya inkasusto na panaggiling, say kapeles na panaggiling et kaslakan ya ag onlampas ed 30m/min. Say kapeles na panaggiling na tapew na balbula et misiglaotan ed materyal na tapew na balbula. Say kapeles na panaggiling na tapew na gansa tan cast iron et 10~45m/min; say sealing surface na hardened steel tan hard alloy et 25~80m/min; say panagselyo na tapew na austenitic stainless steel 10~25m/min.
4. presyon na panaggiling
Say inkaepektibo na panaggiling et ondarakel no ondarakel so presyon na panaggiling, tan say presyon na panaggiling et nepeg ya aliwan atagey, kaslakan et 0.01-0.4MPa.
No gilingen so sealing surface na cast iron, copper tan austenitic stainless steel, say grinding pressure et 0.1~0.3MPa; say sealing surface na hardened steel tan hard alloy et 0.15~0.4MPa. Mangala na mas baleg a balor parad magaspang a panaggiling tan melag a balor parad maong a panaggiling.
5. Allowance ed panaggiling
Lapud say panaggiling et proseso na panagsumpal, say karakel na panagputot et daiset labat. Say kabaleg na grinding allowance et mandedepende ed inkasusto na panag-machining tan say inka-magaspang na tapew na akaunan proseso. Diad silong na premis ya naseguro so pangekal ed saray bakat na proseso na akaunan proseso tan pangipetek ed geometric error na sealing ring, no mas melag so grinding allowance, mas maong.
Say tapew na seal et nepeg ya pinoen antis ya gilingen. Kayari na maong ya panaggiling, say sealing surface et nayarin direktan i-lapped, tan say sankaabebaan ya grinding allowance et: say diameter allowance et 0.008~0.020mm; say allowance na eroplano et 0.006~0.015mm. Mangala na melag a balor no say manual grinding odino material hardness et atagey, tan mangala na baleg a balor no say mechanical grinding odino material hardness et abeba.
Say sealing surface na valve body et aliwan kombeniente ya gilingan tan iproseso, kanian nayarin usaren so fine turning. Kayari na panag-turn, say sealing surface et nepeg ya magaspang so dalin antis ya nasumpal, tan say plane allowance et 0.012~0.050mm.
Say Tianjin tanggu water-seal valve Co.,ltd et espisipisyal ed panaggawamabiskeg ya akayurong ya balbula na kulibangbang, gate valve, Y-strainer, balbula na panagbalanse, wafer check valve, tan arum ni.
