Yintoni enokusetyenziselwa iiFlanged Ball Valve: Usetyenziso

Yintoni iValve yeBhola eFlanged

Ivalvu yebhola ejikelezileyoluhlobo lwevalvu ejika ikota esebenzisa ibhola engenanto, eneembobo, nejikelezayo ukulawula ukuhamba kolwelo. Igama elithi “flanged” libhekisa kwindlela yokudibanisa ivalvu: ineeflanges kuzo zombini iziphelo, ezibotshelelwe kwiiflanges ezifanayo kwimibhobho okanye kwizixhobo. Olu yilo luqinisekisa uqhagamshelo oluqinileyo, olungavuziyo, nto leyo eyenza iivalvu zebhola eziflangekileyo zilungeleuxinzelelo oluphezulukwayeubushushu obuphezuluizicelo.

Ibhola engaphakathi kwivalvu inembobo embindini wayo. Xa ivalvu ivuliwe, imbobo ihambelana necala lokuhamba, ivumela ulwelo ukuba ludlule. Ukujikeleza isiphatho okanye i-actuator ngama-90 degrees kuvala ivalvu, kubeka imbobo ngokuthe nkqo kukuhamba kwayo kwaye kuyithintele. Iivalvu zebhola ezijijekileyo zaziwa ngokuthembeka kwazo, ukusebenza ngokukhawuleza, kunye nokunciphisa uxinzelelo.

Ubungakanani, Izinto, kunye noLuhlu loXinzelelo lweeFlanged Ball Valve

Uluhlu lobungakanani

Iivalvu zebhola ezine-Flanged ziyafumaneka ngobukhulu obahlukeneyo ukuze zilungele iinkqubo ezahlukeneyo zemibhobho:

• Ububanzi:Ngokwesiqhelo ukusuka½ intshi (DN15)ukuyaIi-intshi ezingama-48 (DN1200).

   • Izibuko Elipheleleyo (Ibhore Elipheleleyo):Ububanzi bebhore buhambelana ne-ID yombhobho, nto leyo enciphisa ukunqongophala kwamanzi.
   • Izibuko Elincitshisiweyo (Ibhoreji Eqhelekileyo):Ibhore encinci yezicelo ezixabisa kakhulu.

2. Ngoyilo:

   • Ibhola Elidadayo:Ibhola ibanjwe endaweni yayo zizihlalo ezibini; ifanelekile kwiinkqubo ezinoxinzelelo oluphantsi.
   • Ibhola efakwe kwiTrunnion:Ibhola iqiniswe nge-trunnion ukuze ikwazi ukuzinza xa ixinzelelwe ngamandla.

3. Ngomsebenzi:

   • Iindlela ezimbini (iiPort ezimbini):Ulawulo olusisiseko lokuhamba komoya xa uvula/ucima.
   • Iindlela Ezintathu (Izibuko Ezi-3):Ukudibanisa okanye ukuxuba ukuhamba kwamanzi.
   • Iivalvu zeBhola ze-V-Port:Ulawulo lokuhamba ngokuchanekileyo olunembobo enomfanekiso ongu-V.

Iingenelo zeeFlanged Ball Valve

1. Uyilo Olungavuziyo:Uqhagamshelo oluneflange luqinisekisa ukutywinwa okuqinileyo phantsi koxinzelelo oluphezulu.
2. Ukuqina:Ulwakhiwo oluqinileyo lumelana nokuguguleka, ukugqwala, kunye noxinzelelo lobushushu.
3. Ukusebenza ngokukhawuleza:Ukujikeleza nge-90-degree kwenza kube lula ukuvula/ukuvala ngokukhawuleza.
4. Ulondolozo oluphantsi:Izinto ezimbalwa ezihambayo ziyanciphisa iimfuno zenkonzo.
5. Ukuguquguquka:Iyahambelana nezinto ezimanzi, iigesi, kunye ne-slurry.

Yintoni enokusetyenziselwa iiFlanged Ball Valve

Iivalvu zebhola ezineFlanged zidlala indima ebalulekileyo ekulawuleni ulwelo:

• Ukubekwa wedwa:Cima ukuhamba kwamanzi ngexesha lokulungiswa okanye ngexesha likaxakeka.
• Ulawulo lokuhamba komoya:Uyilo lwe-V-port luvumela ukugoba.
• Ulawulo loxinzelelo:Ukumelana nokunyuka koxinzelelo oluphezulu.
• Ukuhlanganiswa kweeNkqubo ezininzi:Qhagamshela iimpompo, iitanki, kunye nemibhobho ngeeflanges.

Ukukwazi kwabo ukujongana neemeko ezinzima (umz., amaqondo obushushu arhabaxa, ukurhawuzelelwa okurhabaxa) kubenza babaluleke kakhulu kumashishini afuna ukuthembeka nokhuseleko.

Isiphelo

Iivalvu zebhola ezijijekileyoZizinto ezinokuguquguquka, ezihlala ixesha elide, nezisebenzayo kwiinkqubo zolawulo lolwelo. Ngeendlela ezahlukeneyo ezinobungakanani obuqala kwi-½” ukuya kwi-48″, izinto ezifana nentsimbi engatyiwayo kunye ne-PTFE, kunye novavanyo loxinzelelo olufikelela kwi-5,000 PSI, ziyahlangabezana neemfuno zamashishini aqala kwioyile negesi ukuya kunyango lwamanzi. Uyilo lwazo olune-flange luqinisekisa ukufakwa okukhuselekileyo, ngelixa ulungelelwaniso oluphambili (umz., olufakwe kwi-trunnion, oluneendlela ezintathu) lwandisa ukusebenza kwazo. Nokuba zihlukanisa imibhobho, zilawula ukuhamba kwamanzi, okanye zilawula umphunga oxinzelelo oluphezulu, iivalvu zebhola ezi-flange zibonelela ngokusebenza okungenakuthelekiswa nanto kwizicelo ezibalulekileyo.
