Isikhokelo seValve yokujonga ibhola: Indlela esebenza ngayo, iintlobo, iingenelo kunye neengozi

Kwihlabathi elikhulu leenkqubo zolawulo lolwelo kunye nemibhobho yamanzi, ukuqinisekisa ukuba ukuhamba kwamanzi kuhamba kwicala elinye kubalulekile. Phakathi kweentlobo ngeentlobo zeevalvu zokujonga ezenzelwe le njongo, ivalvu yokujonga ibhola ivelele ngokulula kwayo, ukuthembeka kwayo, kunye nokusebenza kwayo kakuhle. Esi sikhokelo sinika umbono onzulu weevalvu zokujonga ibhola, sichaza ukusebenza kwazo, iingenelo, kunye nendlela yokuzifumana kubaboneleli abasemgangathweni kwihlabathi liphela naseTshayina.

Yintoni iValve yokujonga ibhola

Ivalvu yokujonga ibhola luhlobo lwevalvu yokujonga, okanye ivalvu engabuyiyo, esebenzisa ibhola engqukuva ukulawula indlela ukuhamba kolwelo. Umsebenzi wayo oyintloko kukuvumela ukuhamba kwicala elinye ngelixa uthintela ngokuzenzekelayo ukuhamba kwakhona (ukuhamba okungasemva) xa uxinzelelo lolwelo luyehla. Uyilo lulula: ibhola ihlala kwigumbi, kwaye uxinzelelo lolwelo luyayiphakamisa ukuze ivumele ukuhamba; xa uxinzelelo luncipha, amandla adonsela phantsi okanye uxinzelelo olungasemva lunyanzela ibhola ukuba ibuyele esihlalweni sayo, ivale ivalvu. Zisetyenziswa rhoqo kwizicelo ezisusela kwiimpompo zamanzi kunye neenkqubo zepetroli ukuya ekucutshungulweni kweekhemikhali kunye nokusetyenziswa kweemoto.

Izinto eziyinxalenye yeValve yokujonga ibhola

Ubulula bevalvu yokujonga ibhola bubonakala kwinani elincinci lamalungu ayo. Izinto eziphambili ziquka:

Umzimba/Indlu:

Igumbi eliphambili eliqulethe zonke ezinye izinto, ezenziwe ngesinyithi ezifana nobhedu okanye intsimbi engatyiwayo, okanye iiplastiki ezifana nePVC okanye iCPVC, kuxhomekeke kwisicelo.

Ibhola:

I-obturator ejikelezayo ehamba ngokukhululekileyo. Idla ngokwenziwa ngezinto ezihlala ixesha elide, ezingamelani nokugqwala ezihlala zixinene kunolwelo olulawulwa yiyo (umz., isinyithi esigqunywe ngerabha, irubhi yokwenziwa, okanye iPTFE).

Isihlalo:

Umphetho apho ibhola iphumla khona ukuze yenze isitywino kwaye imise ukubuya kwamanzi. Isihlalo sihlala sijikeleziswa ukuze siholele ibhola kwisitywino esigqibeleleyo kwaye singenziwa ngezinto ezithambileyo okanye sibe ne-O-ring ukuqinisekisa ukuvalwa okuqinileyo.

Intwasahlobo (Ukhetho):

Kwezinye iindlela zoyilo, intwasahlobo isetyenziselwa ukunceda ekuvaleni ivalvu, ingakumbi kwiindawo apho umxhuzulane ungenakuthenjelwa khona (umz., imibhobho ethe tye okanye iinkqubo eziphantsi koxinzelelo).

Indlela iValve yokujonga ibhola esebenza ngayo kunye nomsebenzi wayo

Umgaqo osebenzayo wevalvu yokujonga ibhola ulula kakhulu kwaye usekelwe kwi-fluid dynamics kunye noxinzelelo oluhlukeneyo.

Ukuhamba Phambili (Imeko evulekileyo):Xa uxinzelelo oluphezulu (uxinzelelo lokungena) ludlula uxinzelelo olusezantsi kunye namandla afunekayo ukuphakamisa ibhola (nokoyisa amandla entwasahlobo ukuba akhona), ibhola iyatyhalelwa kude nesihlalo sayo. Oku kudala umngxuma, ovumela ulwelo ukuba lujikeleze ibhola kwaye ludlule kwivalvu.

Ukuthintela Ukugeleza/Ukubuyela Umva Kwendlela (Imeko Evaliweyo):Xa uxinzelelo oluphezulu luhla, lulingana, okanye lubuyela umva (ukuhamba emva), indibaniselwano yomxhuzulane kunye noxinzelelo olungasemva lolwelo lutyhala ibhola ibuyele esihlalweni sayo. Ibhola isebenza njengeplagi, idala isitywina esiqinileyo esithintela ngokufanelekileyo nayiphi na indlela ebuyela umva, ikhusela izixhobo ezinobuthathaka ezisezantsi.

Umsebenzi wayo oyintloko kukulawula ukuhamba komoya ngokuzenzekelayo, okusebenza ngoxinzelelo oluya kwicala elinye ngaphandle kwesidingo sokusebenza ngesandla okanye iinkqubo zolawulo lwangaphandle.

Iingenelo zeValve yokujonga ibhola

Iivalvu zokujonga ibhola zibonelela ngezibonelelo ezahlukeneyo:

Uyilo olulula:Ngenxa yokuba zincinci kakhulu iindawo ezishukumayo, kulula ukuzenza, ukuziqonda nokuzigcina zisemgangathweni.

Ukuthembeka:Indlela elula inika ukuthembeka okuphezulu kunye namanqaku amancinci okusilela.

Ukufaneleka kweViscous Fluids:Zilungile kakhulu ekuphatheni udaka, amanzi amdaka, kunye nezinye izinto ezithambileyo ezinokubangela ukuba ezinye iintlobo zeevalvu zokujonga (ezifana neevalvu zokujonga i-swing okanye i-wafer) zinamathele okanye zingasebenzi.

Impendulo ekhawulezileyo:Zibonelela ngesenzo sokuvala ngokukhawuleza, zinciphisa ngempumelelo ihamile yamanzi (nangona ingafani nezinye iindlela zoyilo lwevalvu yokujonga engashukumiyo).

Ukuguquguquka:Ifumaneka kwiindidi ezahlukeneyo zezinto zokwakha, ubungakanani, kunye novavanyo loxinzelelo ukuze ilungele amashishini ahlukeneyo.

Ivalvu Yokujonga Ibhola vs. Ivalvu Yebhola

Le yinto eqhelekileyo ebangela ukudideka ngenxa yamagama afanayo, kodwa ahluke ngokupheleleyo.

Kufuphi:A ivalvu yebholayeyokumisa okanye ukuqala ukuhamba ngesandla, ngelixa ivalvu yokujonga ibhola iyindlela yokuqinisekisa ngokuzenzekelayo ukuba ukuhamba kuhamba calanye kuphela.

Ivalvu Yokujonga Ibhola vs. Ivalvu Yokujonga

Ivalvu yokujonga ibhola ngokweneneuhlobo olungaphantsiyodidi olubanzi lwevalvu yokujonga. Igama elithi “ivalvu yokujonga"yinto eqhelekileyo. Nantsi indlela uyilo lwebhola oluthelekiswa ngayo nezinye iintlobo zevalvu yokujonga eqhelekileyo:

I-Valve yokujonga iSwing vs.

Iivalvu zokujonga ukujikaSebenzisa i-flapper ejikajika kwi-hinge. Ngokwesiqhelo zinamandla aphezulu okuhamba kwamanzi kunye nokwehla koxinzelelo oluphantsi kodwa azilungele ulwelo oluxineneyo okanye iipatheni zokuhamba kwamanzi ezingaguquguqukiyo apho i-flapper inokuxokozela khona. Iivalvu zokujonga ibhola ziphatha ngcono i-viscosity.

Ivalvu yokujonga ukuphakanyiswa xa ithelekiswa neLift:

Iivalvu zokujonga ukuphakanyiswa zisebenzisa i-piston okanye idiski ephakamisa ngokuthe nkqo. Ziyafana ngomsebenzi kodwa uyilo lwebhola lunokumelana nezinto ezininzi ezingcolisayo kunye nenkunkuma ngaphandle kokungcolisa.

Ivalvu yokujonga iWafer vs.

Iivalvu zokujonga iiwafer zincinci, zikhaphukhaphu ezibekwe phakathi kweeflange. Iivalvu zokujonga ibhola zihlala ziqinile kodwa zihlala zinesithuba esikhulu sokufakelwa.

Uhlobo lwebhola ludla ngokukhethwa ngenxa yokukwazi kwalo ukusingatha iindaba ezinengxaki.
