Qonda iimpawu zentsimbi ekhandiweyo iivalve zebhola ezisisigxina

Ehlabathini leevalvu zoshishino, iivalve zentsimbi ezifakwe kwi-trunnion-mounted ball zibonakala njengendlela enqabileyo kwaye ethembekileyo kwiinkqubo ezahlukeneyo. Ezi zivalo zenzelwe ukulawula ukuhamba kolwelo kwimibhobho, nto leyo ezenza zibe yinxalenye ebalulekileyo kumashishini afana ne-oyile negesi, ukucocwa kwamanzi, ukusetyenzwa kweekhemikhali kunye nokuveliswa kwamandla.

Yintoni ivalve yebhola efakwe kwitrunnion eyenziwe ngentsimbi?

Ngaphambi kokungena kwezi mpawu, kuyimfuneko ukuqonda ukuba yintoni ivalve yebhola eqingqiweyo yentsimbi. Olu hlobo lwevalve lubandakanya i-disc spherical (ibhola) ejikeleza ngaphakathi kumzimba wevalve ukulawula ukuhamba kwamanzi. Igama elithi "trunnion mount" libhekisela kuyilo apho ibhola ixhaswa yi-trunnions (i-pivot points) phezulu nasezantsi, eyandisa ukuzinza kunye nokunciphisa ukunxiba. Umzimba wevalve udla ngokwenziwa ngentsimbi ekhandiweyo, eyongeza kumandla kunye nokuqina.

Iimpawu eziphambili zentsimbi ekhandiweyo yevalve yebhola esisigxina

1. Ukuqina kunye nokomelela

Enye yezona zinto zibalulekileyo eziluncedo kwi-trunnion yentsimbi efakwe kwiivalvu zebhola kukuqina kwazo. Inkqubo yokubumba ibandakanya ukubunjwa kwentsimbi phantsi koxinzelelo oluphezulu, okubangela ukuba kubekho izinto ezixineneyo nezinamandla. Oku kuvumela i-valve ukuba imelane noxinzelelo oluphezulu kunye namaqondo okushisa, okwenza ukuba ilungele izicelo ezifunwayo. Ulwakhiwo olomeleleyo lukwanciphisa umngcipheko wokuvuza kwaye luqinisekisa itywina elithembekileyo.

2. ITorque esebenzayo ephantsi

Uyilo lwevalvu yebhola exhonywe kwi-Trunnion kufuna i-torque encinci ukusebenza kuneevalvu zebhola ezidadayo. Oku kungenxa yoyilo lwe-trunnion oluxhasa ibhola kunye nokunciphisa ukukhuhla ngexesha lokusebenza. Ngoko ke, nangona ubukhulu bazo obukhulu, ezi zivalo zinokusebenza ngokulula, zizenze zilungele iinkqubo ezizenzekelayo usebenzisa i-actuator.

3. Iimpawu ezihamba kakuhle

Uyilo lwevalve yebhola efakwe kwi-trunnion ivumela indlela epheleleyo yokuhamba kwezibuko, oku kuthetha ukuba ivalve inomlinganiselo wangaphakathi ofanayo nombhobho. Olu phawu lunciphisa ukuhla koxinzelelo kunye nesiphithiphithi, siqinisekisa ukuhamba kwamanzi okusebenzayo. Ubuso obugudileyo bebhola bunceda ekunciphiseni ukungqubana, ngaloo ndlela kuphuculwe ukusebenza ngokupheleleyo kwevalve.

4. Ukuguquguquka kweApp

Iivalvu zebhola ezenziweyo zenziwe nge-trunnion efakwe kwizinto ezininzi kwaye zinokusetyenziswa kwizinto ezahlukeneyo kumashishini ahlukeneyo. Zikulungele ukuphatha ulwelo, iigesi kunye ne-slurries kwaye zilungele ukuveliswa kweoli kunye negesi, ukusetyenzwa kweekhemikhali, ukunyangwa kwamanzi kunye nokuveliswa kwamandla. Ukukwazi kwabo ukusebenza kwiimeko ezimandundu kwandisa ngakumbi ukufaneleka kwabo.

5. Uyilo olungatshiyo

Iivalvu zebhola ezininzi ezenziwe nge-trunnion zentsimbi ziyilelwe ukuba zikwazi ukumelana nomlilo, nto leyo ebaluleke kakhulu kumashishini aphatha izinto ezinokutsha. Ezi zivalo zakhiwe ukuthintela ukuvuza xa kukho umlilo, ukuqinisekisa ukhuseleko kunye nokuthotyelwa kwemigangatho yoshishino. Uyilo olungatshiyo luhlala lubandakanya izinto ezifana nezihlalo zentsimbi ukuya kwintsimbi kunye nokutywinwa kwesibini.

6. Kulula ukuyigcina

Ugcino ngumba obalulekileyo wokusebenza kwevalvu, kwaye iivalvu zentsimbi ezifakwe kwitrunnion ezixhonywe kwintsimbi yenzelwe ukuba kube lula ukugcinwa. Iivalvu zinokusetyenzwa ngaphandle kokuzisusa kumbhobho, ukonga ixesha kunye nokunciphisa ixesha lokuphumla. Ukongeza, uyilo olulula lwevalve luvumela ukuhlolwa ngokukhawuleza kunye nokutshintshwa kwezinto, ukuqinisekisa ukuba i-valve ihlala ilungile.

7. Iinketho ezinokwenziwa ngokwezifiso

Abavelisi bahlala bebonelela ngeendlela ezinokwenziwa ngokwezifiso kwiivalvu zebhola ezifakwe kwi-trunnion yentsimbi, evumela abasebenzisi ukuba bakhethe iimpawu ezihlangabezana neemfuno zabo ezithile. Oku kubandakanya iinketho zezinto ezahlukeneyo, ubungakanani, ukulinganiswa koxinzelelo kunye nokudibanisa ekupheleni. Ukwenza ngokwezifiso kuqinisekisa ukuba i-valve inokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezizodwa zaso nasiphi na isicelo.

8. Ukusebenza kokutywinwa

Ukusebenza kokutywina kwevalvu kubalulekile ekuthinteleni ukuvuza kunye nokuqinisekisa ukusebenza ngokufanelekileyo. Iivalvu zebhola ezenziweyo ezifakwe kwi-trunnion zibandakanya izinto ezikumgangatho ophezulu zokutywina ezibonelela ngokugqwesileyo kunye nokuxhathisa ukubola. Uyilo lukwavumela ukusetyenziswa kwezixhobo ezahlukeneyo zokutywina, ukuphucula amandla e-valve ukugcina isitywina esiqinileyo phantsi kweemeko ezahlukeneyo.

9. Ukusebenza kweendleko

Ngelixa utyalo-mali lokuqala kwi-valve yentsimbi ye-trunnion-mounted ball valve ingaba phezulu kunezinye iintlobo zeevalvu, ukuqina kwayo kunye neemfuno eziphantsi zokugcinwa zihlala zikhokelela ekugcinweni kweendleko zexesha elide. Isidingo esincitshisiweyo sokulungiswa kunye nokutshintshwa, kunye nokusebenza kwabo ngokufanelekileyo, kubenza ukuba babe ukhetho olungabizi kakhulu kumashishini amaninzi.
