Lok me acaki pa Butterfly Valve

Nyute:

Gin ma ki lwongo ni butterfly valveoa ki i dul pa valve ma ki lwongo nidul ma ki lwongo ni quarter-turn valves. I tic, gin ma ki lwongo ni valve ni oyabe onyo ki umu ka ki loko disc ni pi tyen angwen. "Butterfly" obedo gin ma ki yubu ki nyonyo ma ki keto i kom yat. Ka valve ni ki umu, ki loko disc ni wek ogengo yoo ni woko. Ka gin ma ki lwongo ni valve ni oyabe, ki loko gin ma ki lwongo ni disc ni nucu me weko pii ni kato labongo gengo. Gin ma ki lwongo ni valve ni ki twero yabo mot mot me juku pii.

Tye dul ma pat pat ma ki lwongo ni butterfly valves, acel acel ki yubu pi rwom me tic ma pat pat ki tic ma pat pat. Gin ma ki lwongo ni zero-offset butterfly valve, ma tiyo ki jami ma ki lwongo ni rubber, tye ki rwom me teko ma lapiny loyo. Gin ma ki lwongo ni high-performance double offset butterfly valve, ma ki tiyo kwede i jami ma tye ki rwom ma malo manok, ki kwanyo ki i dyere pa disc seat ki body seal (offset acel), ki center line pa bore (offset aryo). Man miyo tic pa cam i kare me tic me tingo kom ni ki i kom gin ma ki umu ma weko bedo ki buru manok ma loyo ma ki yubu i yub ma pe ki keto iye ki dwoko piny rwom me rweny ne. Gin ma ki lwongo ni valve maber pi jami ma tye ki teko madwong en aye triple offset butterfly valve. I valve ni dul ma ki lwongo ni disc seat contact axis ni ki keto woko, ma tiyo me kwanyo rwate ma tye i kin disc ki seat. I kom dul ma ki lwongo ni triple offset valves, kom ni ki yubu ki nyonyo wek ki twero tic kwede me nongo bubble tight shut-off ka orwate ki disc.

kit

1. Concentric butterfly valves– dul ma ki lwongo ni valve ni tye ki kom ma ki yubu ki jami ma ki lwongo ni metal disc.
2. Dubly-excentric butterfly valves(high-performance butterfly valves onyo double-offset butterfly valves) – jami ma pat pat ki tiyo kwede me yubu kom ki gin ma ki lwongo ni disc.
3. Triply-eccentric butterfly valves(triple-offset butterfly valves) – kom ni ki yubu ki laminated onyo ki yubu ki nyonyo.

Wafer-style butterfly valves

Gingin ma ki lwongo ni wafer style butterfly valveki yubu me gwoko gin ma umu i kom apoka poka me rwom me yamo ma tye tung ariiyo me gengo pii ma dwogo cen i yub ma ki yubu me mol tung acel. En tiimo man ki gin ma ki keto maber; ma calo, gasket, o-ring, ma ki yubu maber, ki valve ma nen maber i tung malo ki piny pa valve ni.

Lug-style butterfly valve

Lug-style valvestye ki jami ma ki keto i dul kom valve ni weng. Man miyo gi twero me keto gi i yub kun kitiyo ki bolts aryo ki labongo nuts. Gin ma ki lwongo ni valve ni ki keto i kin flange aryo kun kitiyo ki bolt ma pat pat pi flange acel acel. Kit ma ki yubu kwede ni weko dul acel acel me yub me pii ni ki kwanyo labongo balo dul mukene ni.

Gin ma ki lwongo ni lug-style butterfly valve ma ki tiyo kwede i dead end service pol kare tye ki pressure ma piny. Me labolle, gin ma ki lwongo ni lug-style butterfly valve ma ki keto i kin flanges aryo tye ki 1,000 kPa (150 psi) me rwom me teko. Valve acel-lu ma ki keto ki flange acel, i tic ma pe ki tiyo kwede, tye ki 520 kPa (75 psi) rating. Lugged valves gi tek tutwal i kom jami ma ki lwongo ni chemical ki solvents ki twero tic ki lyeto ma romo 200 °C, ma miyo bedo gin ma tiyo maber.

Tic kwede i gang tic

I dul ma yubu yadi, jami ma ki lwongo ni chemical, ki cam, gin ma ki lwongo ni butterfly valve ki tiyo kwede me juku mol pa jami (ma tek, ma pii, yamo) i kin jami ma ki yubu. Valve ma kitiyo kwede i tic magi pol kare ki yubu gi malube ki cik pa cGMP (kit me yubu ne maber i kare ni). Butterfly valves pol kare gi loko ball valves i kampuni mapol, tutwale petroleum, pi wel ma lapiny ki yot me keto ne, ento paip ma tye ki butterfly valves pe kitwero 'keto' me lwoko.
