Butterfly Valve acaki

Nyithiri:

Barterfly valveuai kud i ot pa valve ma julwongo nivalves ma loko wang angwen. I tic, valve ne oyabere nyo cego ka disc ne utur wang angwen. "Butterfly" ubedo diski mi cuma ma juketho iwi yen. Ka valve cego, disc ne lokore kara egeng dhugola. Ka valve oyabere, disc ne judwoko wang angwen kara ewek pii ucidhi maber. Valve copo bedu ma oyabere nya yot yot pi dwoko pii ma mol.

Tye kit butterfly valves matung tung, acel acel juyike pi kero matung tung man tic matung tung. Zero-offset butterfly valve, ma tiyo ku kero pa rubber, utiye ku pressure rating ma piny uloyu. High-performance double offset butterfly valve, ma jutiyo kudu i system ma tek nyanok, jupoko kud i dyere pa disc seat man body seal (offset acel), man dyere pa bore (offset aryo). Eni ketho cam timo tic ikare mi tic mi tingo kom woko kud i seal ma kelo friction manok uloyu ma juyubu i zero offset design man dwoko piny rwom pare mi rwinyo. Valve maber uloyu pi tic ma tek utiye triple offset butterfly valve. I valve eni, disc seat contact axis utiye offset, ma timo tic mi jwigo sliding contact axis ikind disc ku seat. I lembe pa triple offset valves, kom ne juyike ku cuma kara ecopu tiyo kudu pi ketho bubble tight shut-off ka etuc ku disc.

Kit

1. Concentric butterfly valves– kit valve eni utiye ku kom maber pa rubber ku disc mi cuma.
2. Double-excentric butterfly valves(high-performance butterfly valves or double-offset butterfly valves) – kit piny matung tung jutiyo kudu pi kom man disc.
3. Triply-eccentric butterfly valves(triple-offset butterfly valves) – kom ne juyike ku laminated nyo kom ma juyubu ku cuma.

Wafer-style butterfly valves

Kuwafer style butterfly valvejuyike ni gwoko cing ikum tung tung pa pressure ma wok kud i yore aryo ni juku dwoko piny moko ci i yub ma juyike pi ngwec ma tung tung. Etimu eni ku cing ma ucungo maber; niwacu, gasket, o-ring, ma juyubu maber, man valve ma lageng iwi thenge ma malu man piny pa valve.

Lug-style butterfly valve

Lug-style valvesbedu ku threaded inserts i thenge ario zo pa valve body. Eni weko ju ketho gi i yub moko ma jutiyo kudu ku bolts aryo man nuts epe. Valve ne juyike ikind flanges aryo ku tiyo ku bolts matung tung pi flange acel acel. Yub eni weko thenge acel acel mi piping system juwodhe labongo nyayu peko i thenge mange.

Lug-style butterfly valve ma jutiyo kudu i dead end service pol kare utiye ku pressure rating ma nok. Ku lapor, lug-style butterfly valve ma juketho ikind flanges aryo utiye ku 1,000 kPa (150 psi) pressure rating. Valve marom ma juketho ku flange acel, i tic ma rwinyo, utiye ku 520 kPa (75 psi) rating. Lugged valves gibedo ku tego madit ikum kemikol man solvents man gicopo tingo lyethu ma romo 200 °C, ma weko etiye piny maber.

Ti ku tic i tic

I tic mi yath, kemikol, man cam, butterfly valve jutiyu kudu pi juku mol pa piny (ma tek, ma pii, ma yamo) ikind tic. Valve ma jutiyo kudu i tic eni pol kare juyike nimakere ku cik pa cGMP (tic maber mi yubu piny kawoni). Butterfly valves pol kare giloko ball valves i tic madwong, asaga petroleum, pi bei ma yot man yot mi kethu, ento pipelines ma tye ku butterfly valves copo bedu ngo 'pigged' pi yweyu.
