Zisetyenziselwa ntoni iivalvu zeBhola?

Iivalvu zebhola zizinto eziyimfuneko kwiinkqubo zolawulo lwe-fluid, ezaziwa ngokuthembeka kwazo, ukuguquguquka, kunye nokusebenza kakuhle kuwo wonke amashishini. Ukusuka kwimibhobho yezindlu zokuhlala ukuya kwizixhobo zeoyile enzulu yolwandle, ezi zivalo zekota zidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo, iigesi, kunye nemithombo yeendaba eqinileyo. Kwesi sikhokelo esibanzi, siza kuntywila kwindlela ezisebenza ngayo iivalvu zebhola, iinzuzo zazo eziphambili, izicelo eziqhelekileyo, kunye neendlela ezizayo—zikuxhobisa ngolwazi lokukhetha nokusebenzisa ngokufanelekileyo.

Zisebenza njani iivalvu zeBhola

Embindini wazo, iivalve zebhola zisebenza ngendlela elula kodwa esebenzayo: idiskhi ejikelezayo engqukuva (“ibhola”) enebhore esembindini (umngxuma) ilawula ukuhamba kwamanzi. Ukusebenza kwevalve kuxhomekeke kumacandelo amathathu angundoqo: umzimba wevalvu (ogcina amalungu angaphakathi aze aqhagamshelene nemibhobho), ibhola enemingxuma (undoqo olawula ukuvuleka nokuvala), kunye nesiqu (esithumela amandla ajikelezayo ukusuka kwi-actuator ukuya ebholeni).

Xa umbhobho webhola uhambelana nombhobho, ivalve ivuleke ngokupheleleyo, ivumela ukuqukuqela okungaphazanyiswayo. Ukujikelezisa ibhola ngee-degrees ezingama-90 (ukujika kwekota) kubeka indawo eqinileyo yebhola ngaphaya kwendlela yokuqukuqela, ukuvala ukuqukuqela ngokupheleleyo. I-Actuation ingenziwa ngesandla (nge-lever okanye ivili lesandla) okanye i-automated (i-pneumatic, umbane, okanye i-hydraulic) yolawulo olukude okanye oluchanekileyo. Uyilo olubini oluqhelekileyo luphucula ukuguquguquka: iivalvu zebhola ezidadayo (apho ibhola ijika kancinane phantsi koxinzelelo ukuze itywine) kunye neevalvu zebhola ezifakwe kwi-trunnion (apho ibhola igxininiswe zizikhondo eziphezulu nezisezantsi zosetyenziso olunoxinzelelo oluphezulu).

IiNzuzo eziPhambili zokuSebenzisa iiValuvu zeBhola

Iivalvu zebhola zigqame phakathi kwezisombululo zolawulo lwe-fluid ekusebenzeni kwazo okuqinileyo kunye neenzuzo ezigxile kumsebenzisi:

• Ukuvula nokuvala ngokukhawuleza: Ukujikeleza kwe-90-degree kugqiba imijikelezo epheleleyo evulekileyo / evaliweyo kwisithuba esincinci njengemizuzwana ye-0.5, okwenza kube yinto efanelekileyo kwiimeko zokuvala ngokukhawuleza njengeenkqubo zomlilo okanye ukuvuza kwegesi.
• Ukutywinwa okuPhakamileyo: Iimodeli ze-Soft-seal (PTFE) zifezekisa ukutywinwa kwe-bubble-tight (ukuvuza ≤0.01% KV), ngelixa iinguqulelo ze-hard-seal (zentsimbi) zigcina ukuthembeka kwiimeko eziphezulu zoxinzelelo / ubushushu obuphezulu-ezibalulekileyo kwizinto ezivuthayo kunye neziqhushumbisi okanye ezonakalisayo.
• Ukuchasana nokuHamba okuPhantsi: Iivalvu zebhola ezigcweleyo zibonakalisa ibhore elingana nobubanzi bombhobho, okubangela ukuhla koxinzelelo oluncinci (i-resistance coefficient 0.08-0.12) kunye nokugcinwa kwamandla kwiinkqubo zomthamo omkhulu.
• Ukuqina kunye ne-Versatility: Ukumelana namaqondo okushisa ukusuka kwi -196 ℃ (LNG) ukuya kwi-650 ℃ (ii-furnaces zamashishini) kunye noxinzelelo ukuya kwi-42MPa, ukuziqhelanisa nolwelo, i-gases, kunye ne-particle-laden media njenge-slurry.
• UkuLondolozwa okuLula: Uyilo lweModyuli luvumela ukulungiswa kwe-in-line (akukho disassembly yombhobho) kunye nezitywina ezinokutshintshwa, ukusika ixesha lokugcinwa kwe-50% xa kuthelekiswa neevalve zesango.
