Sarayan amin et importantin bengatla ya ikonsidera ed sistema na panag-seal mo. No amta la so amin a sengegan, mainomay so pampili na dugan materyal.

Balet say nakaukolan et say materyal et nepeg ya malet. Kanian say unonan ikonsidera et say teknikal ya performance. Igapo tayo ed sengegan na performance.

Say bilay na sistema tan say gastos to et importantin bengatla (TIanjin Tanggu Water-Seal Valve Co.,ltd) ya ikonsidera. Amin a bengatla et mangapekta ed performance na aplikasyon mo. Importante ya ikonsidera iray bengatla ed desinyo unong ed aplikasyon. Kaiba ed saya iray materyales ya inusar, saray kurti na kagawaan tan saray proseso na produksyon. Wala met iray bengatlan kaukolan ya ikonsidera ed kaliberliber kaiba lay: presyon, temperatura, oras, panagtipon tan media.

elastomer

Saray elastomer et popular lapud maong ya inka-elastiko ra. Anggapoy arum a materyales ya walaan na parehon lebel na inka-elastiko.

Saray arum a materyales a singa say polyurethane tan thermoplastics et mas makatebek ed pressure nen saray elastomer.

Saray materyales ya goma et nayarin usaren ed nanduruman aplikasyon.

Kaiba ed saray importantin mekanikal a kablian

Kaiba ed arum ya importantin kabiangan

•Set na kompresyon

•resistensya ed petang

•abeban temperaturan nababalang

•pankakasakey na kemikal

•Anti-aging

•resistensya ed gasgas

Say sankaimportantian ya kabiangan et say inka-elastiko na materyal ya goma. Amtaen tayo ni so nipaakar ed saya.

Say inka-elastiko et resulta na vulcanization. Saray elastomeric ya materyales, a singa say vulcanized rubber, et ompawil ed datin kurti da no naderal.

Saray materyales ya ag-onkupas, singa say unvulcanized rubber, et ag-onpawil ed datin kipapasen da no naderal. Vulcanization (singa saydouble flange butterfly valve) et say proseso na panguman ed goma ya magmaliw ya elastomeric ya materyales.

Say pampili na saray elastomer et manunan nibase ed:

•laknab na temperatura ed pantratrabaho

•Resisti ed saray likido tan gas

•Resisti ed panaon, ozone tan UV rays

Anemiran bengatla so nepeg ya ikonsidera no manpipili na materyales ed tapew na balbula

Say sealing surface et sankaimportantian ya pankimeyan nabalbula, say kalidad na tapew na seal et direktan mangaapekta ed bilay na serbisyo nabalbula, tan say materyal na sealing surface et importantin bengatla pian naseguro so kalidad na sealing surface. Kanian, nepeg ya ikonsidera iray onggendan a bengatla no manpipili na materyales ed tapew na balbula:

①Resisti ed kaagnasan. Say “corrosion” et say proseso ya say tapew na sealing surface et naderal lapud kiwas na medium. No say tapew na tapew na sealing et abulok, ag naseguro so performance na sealing, kanian say materyal na sealing tapew et nepeg ya ag-onkupas. Say resistensya ed corrosion na sakey a materyal et mandedepende ed komposisyon na materyal tan say inkapekder na kemikal to.

②Anti-abrasion. Say “scratch” et manutukoy ed pakaderal na friction na materyales legan na relatibon galaw na sealing surface. Sayan klase na pakaderal et seguradon pansengegan na pakaderal na tapew na seal. Kanian, say materyales ed tapew na sealing et nepeg ya walaan na maong ya anti-scratch ya kablian, lalo la parad saray gate valve. Say resistensya na gasgas na sakey a materyal et mabetbet ya nadetermina ed saray walad loob na materyal.

③Resisti ed erosion. Say “erosion” et proseso na pakaderal na sealing surface no say medium et onaagus ed sealing surface ya maples. Sayan klase na destroso et mas napatnagan ed saray throttle valve tan safety valve ya uusaren ed atagey a temperatura tan atagey a presyon na steam media, tan baleg so epekto to ed destroso na sealing performance. Kanian, say resistensya ed erosion et sakey met ed saray importantin kakaukolanen pian naseal iray materyales ed tapew na dalin.

④Nepeg ya walay pigaran inka-malet to, tan say inka-malet to et onleksab a maong ed silong na nibaga ya temperatura na pantratrabahoan.

⑤Say linear expansion coefficient na tapew na sealing tan say materyal na laman et nepeg ya parepareho, ya mas importante parad istruktura na sealing ring, pian napaliisan so ekstran stress tan inkalukas ed atagey a temperatura.

6No usaren ed atagey a temperatura, nepeg ya walay magenap ya anti-oxidation, thermal fatigue resistance tan saray isyu ed thermal cycle.

Diad kaplesan iran sirkumstansya, mairap so mananap na materyales ya pang-seal surface ya sigpot ya makasumpal ed saray kakaukolanen ed tagey. Makapokus tayo labat ed pakasumpal na pigaran aspekto unong ed nanduruman klase tan usar na balbula. Singa bilang, saray balbula ya uusaren ed high-speed media et nepeg ya mangiter na espisyal ya imano ed saray kakaukolanen ya resistensya ed erosion na tapew na sealing; tan no say medium et walaan na solidon impurities, say sealing surface material ya mas atagey so hardness to so nepeg ya pilien.
