Say balbula bilang sakey a kagawaan et nianak ed loob na nilibon taon

Say balbulaet sakey a kagawaan ya uusaren ed pangipasabi tan pangikontrol na gas tan likido ya walaan na ag-onkulang ed sanlibon taon ya awaran.

Diad kaplesan, diad sistema na fluid pipeline, say regulating valve so control element, tan say manunan kimey to et say pangibiig ed kagawaan tan say sistema na pipeline, pangiregula ed agos, pangisebel ed backflow, pangiregula tan pangipaway na pressure. Lapud importante so pampili na sankaabigan ya regulating valve parad pipeline system, importante met so pakatalos ed saray katangian na balbula tan saray kundang tan basiyan ed pampili na balbula.

Nominal ya presyon na balbula

Say nominal ya presyon na balbula et manutukoy ed desinyo ya inter na presyon ya misiglaotan ed mekanikal a biskeg na saray kabiangan na tubo, salanti, saya so naabuloyan ya presyon na balbula ed nibaga ya temperatura, ya misiglaotan ed materyal na balbula. Say working pressure et aliwan pareho, kanian, say nominal pressure et sakey a parametro ya mandedepende ed materyal na balbula tan misiglaotan ed naabuloyan ya temperatura na trabaho tan say presyon na materyal.

Say balbula et sakey a pasilidad ed sakey a medium circulation system odino pressure system, ya uusaren pian na-adjust so agos odino pressure na medium. Saray arum ya kimey et say pangi-off o pangi-switch on ed media, panangontrol ed agos, panguman na direksion na agos na media, pangisebel ed media backflow, tan panangontrol o pangi-vent pressure.

Sarayan kimey et nagawaan diad pangi-adjust ed posisyon na pansara na balbula. Sayan pananguman et nayarin gawaen a manual odino automatiko. Say manual ya operasyon et kaiba met so operasyon na manual ya panangontrol ed drive. Saray balbula ya uusaren na lima et tatawagen ya manual ya balbula. Say balbula ya mangaamper ed pawil na danum et tatawagen ya check valve; say mangokontrol ed relief pressure et tatawagen ya safety valve odino safety relief valve.

Anggad natan, say industriya na balbula et akapangipawala na kompleton klase nasaray balbula na gate, globe valves, throttle valves, plug valves, ball valves, electric valves, diaphragm control valves, check valves, safety valves, pressure reducing valves, steam traps tan emergency shut-off valves. Saray produkto na balbula ya walay 12 kategorya, masulok ya 3000 ya modelo, tan masulok ya 4000 ya detalye; say sankatageyan ya pressure et 600MPa, say sankatageyan ya diametro et 5350mm, say sankatageyan ya temperatura et 1200°C, say sankaabebaan ya temperatura ed trabaho et -196°C, tan say onaplikan medium et say danum, singaw, larak, natural gas, mabiskeg ya makaderal a media (singa say concentrated nitric acid, medium concentration sulphuric acid, tan arum nira).

Imanoen so pampili na balbula:

1. Pian nabawasan so kaaralem na tubo,say balbula na kulibangbanget kaslakan ya napili parad mas baleg a diametro na tubo; say manunan disbentaha na butterfly valve et say butterfly plate et mangookupa na sakey a cross section na danum, ya mamaaligwas ed sakey a head loss;

2. Saray kombensional a balbula et kaibabalbula na kulibangbang, saray balbula na gate, ball valves tan plug valves, tan arum nira. Say karakel na balbula ya uusaren ed water supply network et nepeg ya ikonsidera ed panagpili.

3. Say panag-cast tan panagproseso na saray ball valve tan plug valve et mairap tan magastos, tan kaslakan et matukoy parad melag tan kalatnaan iran tubo. Say ball valve tan plug valve et mansiasiansia ed saray bentaha na single gate valve, melag ya resistensya ed agos na danum, napanmatalkan ya panagselyo, nababalang ya aksion, kombenientin operasyon tan panmintina. Say plug valve et walaan met na mipadparan bentaha, balet say water-passing section et aliwan perpekton sirkulo.

4. No walay daiset ya epekto to ed kaaralem na dalin ya akasakbong, salien ya manpili na gate valve; say katagey na electric gate valve ya baleg so diametro ton vertical gate valve et mangaapekta ed kaaralem na pipeline, tan say karukey na baleg ya horizontal gate valve et mamarakep ed horizontal ya lugar ya okupaan na pipeline tan mangaapekta ed inkauksoy na arum ya pipeline;

5. Diad agano niran taon, lapud inyaligwas na teknolohiya na panag-cast, say pangusar na resin sand casting et makapaliis o makabawas ed mekanikal a panagproseso, kanian nabawasan so gastos, kanian say posibilidad na saray ball valve ya usaren ed angkakabaleg iran tubo et makanakanan usisaen. Nipaakar ed linya na demarkasyon na kabaleg na kalibre, nepeg ya ikonsidera tan naapag unong ed espisipikon situasyon.
