Isikhokelo Esipheleleyo SeeBellows Seal Globe Valves

1. Yintoni iBellows Seal Globe Valve

A I-Bellows Seal Globe Valveluhlobo lwevalvu yeglobhu ene-bellows, eyinxalenye eguquguqukayo netywiniweyo, ukuthintela ukuvuza kolwelo ecaleni kwesiqu sevalvu. Ivalvu yeglobhu ngokwayo yivalvu yokuhamba ethe tye esetyenziselwa ukulawula ukuhamba kolwelo okanye iigesi ngokubhoboza. Ngokufaka ii-bellows, olu yilo lwevalvu lubonelela ngendlela engcono yokutywina ekhusela okusingqongileyo kwaye iqinisekise ukusebenza okukhuselekileyo kwiinkqubo ezifuna ukuchaneka.

Izinto eziphambili:

• Umzimba: Ngokwesiqhelo zenziwe ngezinto ezihlala ixesha elide njengentsimbi yekhabhoni, intsimbi engatyiwayo, okanye ii-alloys.
• IiBellows: Into eguquguqukayo, evaliweyo ethintela ukuvuza ecaleni kwesiqu.
• Idiski/Iplagi: Ilawula ukuhamba kwamanzi ngokuhlala phantsi ecaleni kwesihlalo sevalvu.
• Isiqu: Ibonelela ngendlela yokusebenza kwevalvu, ivumela idiski ukuba ivuleke okanye ivale.
• Ibhonethi: Igcina isiqu kwaye iqinisekisa ukutywinwa kokuvuza kwangaphandle.

2. Isebenza njani iValve yeGlobe yeBellows Seal

Iintsimbi ezikwivalvu yehlabathi zenza umqobo ongenakuvuza phakathi kwesiqu sevalvu kunye nendawo engaphandle. Xa ivalvu isebenza, isiqu siyahamba ukuze silungise indawo yediski. Iintsimbi ziyaguquguquka ukuze zilungele intshukumo yesiqu kodwa zithintele naluphi na ulwelo ukuba lungaphumi, nokuba phantsi kweemeko zoxinzelelo oluphezulu.

Ukuvula/Ukuvala: Xa ivalvu ivuliwe, idiski iyasuka esihlalweni, ivumela ulwelo ukuba ludlule. Xa ivaliwe, idiski iyavala isihlalo, imise ukuhamba kwamanzi.
Ukuhamba kweStem: Isiqu sidlulisela intshukumo ukusuka kwi-actuator ukuya kwidiski. Izikhonkwane ziqinisekisa ukuba akukho manzi anokuvuza ecaleni kwesiqu nangona sihamba.
Ukutywina: Izikhonkwane zigcina uphawu olungenamoya, zithintela izinto eziyingozi ukuba zingaphumi kwaye zingcolise okusingqongileyo.
