Say pandumaan na anlemew tan malet iran seal na balbula:

Unona ed amin, balanglan ball valve itan odinobalbula na kulibangbang, tan arum ni, wala ray anlemek tan malet ya seal, alaen tayo so ball valve bilang alimbawa, say pangusar na anlemek tan malet ya seal na ball valve et mandumaan, nagkalalo la ed istruktura, tan saray estandarte ed panaggawa na balbula et agmanpareho.

Unona, say mekanismo na istruktura

Say hard seal na ball valve et metal-to-metal seal, tan parehon metal so sealing ball tan say yurongan. Say inkasusto tan proseso na panagmakina et medyo mairap, tan kaslakan ya uusaren ed atagey a presyon, kaslakan et masulok ya 35MPa. Saray soft seal et saray seal ed baetan na saray metal tan aliwan metal, singa say nylon\PTFE, tan pareho so estandarte ed panaggawa.

Kumadwa, say materyales ya panag-seal

Say malambot tan malet ya seal so materyales ya pangiseal ed yurongan na balbula, tan say malet ya selyo et eksakton ginawa ed materyal na yurongan na balbula pian naseguro so inkasusto na pantutunosan ed utek na balbula (bola), a kaslakan et stainless steel tan gansa. Say soft sealing et mankabaliksan ya say sealing material ya akaamot ed valve seat et aliwan metal ya materyales, lapud say soft sealing material et walay pigaran inka-elastiko to, kanian say pankaukolan ed inkasusto na panagproseso et mas abeba nen say hard sealing.

Komatlo, say proseso na panaggawa

Lapud dakel so industriya na kemikal, say pantratrabahoan na industriya na makinarya et mas komplikado, dakel so atagey so temperatura tan atagey a presyon, baleg so resistensya na friction na medium, tan mabiskeg so corrosion, natan et inmaligwas so teknolohiya, mas maong so pangusar na nanduruman materyales, tan say panagproseso tan arum niran aspekto et makapipara, kanian say ball valve ya walay hard seal to et malaknab ya inpromote.

Diad tua, say prinsipyo na hard seal ball valve et pareho ed soft seal, balet lapud sakey itan a seal ed baetan na saray metal, kaukolan ya ikonsidera so siglaotan na inka-awet na saray metal, ontan met ed saray kondisyon na pantratrabaho, no antoy medium ya usaren, tan arum nira. Diad inkalapagan, kaukolan so panagpaawet, tan say bola tan say yurongan et naynay ya igiling pian nawalaan na seal. Say siklo na produksyon na hard seal ball valve et andukey, say panagproseso et mas komplikado, tan aliwan mainomay so manggawa na maong a trabaho na hard seal ball valve.

Komapat, saray kondisyon na pangusar

Saray anlemew a selyo et nayarin makaabot ed atagey iran selyo, bangta saray malet a selyo et nayarin atagey odino abeba unong ed saray kakaukolanen; Saray soft seal et kaukolan ya ag-onkapuy, ta no atagey so temperatura, say materyal na soft seal et onlelereg, bangta say hard seal et anggapoy problema to; Saray malet a selyo et nayarin gawaen ya atagey so presyon, balet saray anlemek a selyo et agnayari; Lapud problema ed iyaagus na medium, say soft seal et ag nayarin usaren ed arum ya okasyon (singa say pigaran corrosive media); Say unor ya hard seal valve et mas mabli nen say soft seal valve. No nipaakar ed panaggawa, anggapoy baleg a pandumaan na saratan a dua, say manunan bengatla et say pandumaan na saray yurongan na balbula, say soft seal et aliwan metal, tan say hard seal et metal.

Komalima, diad panagpili na kagawaan

Say pampili na soft tan hard seal ball valves et manunan nibase ed proseso na medium, temperatura tan presyon, say inkalapagan a medium et walaan na solidon partikulo odino walay wear to odino say temperatura et mas atagey nen say 200 degrees, maabig so pampili na hard seals, say diameter to et mas baleg nen say 50, say pandumaan na presyon na balbula et mas baleg, tan say torque na balbula et nilukas met, say malet ya seal et akapeket met say balbula et nepeg ya pilien no mas baleg so torque, antokaman so anlemew tan malet iran selyo, say lebel na seal et nayarin onsabi ed lebel 6.
