Yintoni umahluko phakathi kweValve yokujonga kunye neValve yeBhola

Intshayelelo

Iivalvu ziiqhawe ezingadunyiswanga kwiinkqubo zolwelo lwemizi-mveliso, zisebenza njengeendawo ezibalulekileyo zokulawula ukuhamba kwamanzi, uxinzelelo, kunye nesikhokelo. Kwiinjineli, abayili, kunye neengcali zokuthenga, ukukhetha ivalvu engalunganga kunokukhokelela ekungasebenzi kakuhle kwenkqubo, ixesha lokungasebenzi elibizayo, okanye ukusilela okukhulu. Phakathi kweentlobo eziqhelekileyo kodwa ezihlala zibhideka zeziivalvu yebholakwaye iivalvu yokujongaNangona ngamanye amaxesha zinokubonakala zifana, iinjongo zazo zahlukile ngokupheleleyo. Esi sikhokelo siza kubonelela ngothelekiso olucacileyo noluneenkcukacha ukuze ukwazi ukwenza ukhetho olufanelekileyo kwisicelo sakho.

Yintoni iValvu yeBhola? Isixhobo soLawulo lokuHamba kweMibhobho esiSebenza ngeendlela ezahlukeneyo

Aivalvu yebholayivalvu ejikelezayo yekota esebenzisa ibhola engenanto, ejikelezayo ukulawula ukuhamba. Xa isiphatho sevalvu sijikeleziswa, ibhola iyajikeleza. Umngxuma (imbobo) ophakathi kwebhola uhambelana nendlela yokuhamba ukuze uvumele imidiya ukuba idlule okanye ihlale ithe nkqo ukuze iyivale ngokupheleleyo.

Uyilo kunye nokusebenza okungundoqo

Umsebenzi ophambili wevalvu yebhola kukusebenza njengesixhoboisixhobo sokuvala/sokuvulaInika ukuvalwa okuthembekileyo, okungenamaqamza kwaye yaziwa ngokukwazi kwayo ukuvala kakuhle, ukunciphisa uxinzelelo oluncinci, kunye nokusebenza ngokukhawuleza.

OkuqhelekileyoIintlobo zeeValve zeBhola

• Ivalvu yeBhola yeNtsimbi Engagqwaliyo: Ilungele iindawo ezingcolisayo, ukusetyenziswa okucocekileyo okuphezulu, kunye nobushushu obugqithisileyo. Isetyenziswa kakhulu kwimizi-mveliso yamakhemikhali, yokutya neziselo, kunye namayeza.

•I-Industrial Ball Valve: Udidi olubanzi oluyilelwe ukusetyenziswa kakhulu kwioyile negesi, unyango lwamanzi, kunye nezityalo zamandla. Zihlala zinezakhiwo eziqinisiweyo kunye nezinto eziqinileyo ezifana nentsimbi yekhabhoni.

•Iivalvu zeBhola eziZenzekelayo: Ixhotyiswe ngee-actuators zombane, ze-pneumatic, okanye ze-hydraulic zokulawula kude kunye nokudibanisa kwiinkqubo ze-process automation.

•Ivalve yeBhola eQokelelweyo: Iqulethe imisonto ye-NPT okanye ye-BSPT ukuze kube lula ukuyifakela kwiinkqubo zemibhobho emincinci ngaphandle kokuwelda.

•Ivalvu yeBhola yeHydraulic: Yenzelwe ngokukodwa ukujongana noxinzelelo oluphezulu olufumaneka kwiinkqubo ze-hydraulic, ezidla ngokwenziwa ngekhabhoni enamandla aphezulu okanye intsimbi engatyiwayo.

Yintoni i-Check Valve? Umgcini we-Flow Direction

Aivalvu yokujonga, okanye ivalvu engabuyiyo (i-NRV), sisixhobo sokhuseleko esizenzekelayo esenzelwe ukuvumela ulwelo ukuba luhambe kwicala elinye kuphela. Injongo yaso kuphela kukuthintela ukuhamba okungasemva okunokonakalisa nokungasebenzi kakuhle (ukuhamba emva).

Uyilo kunye nokusebenza okungundoqo

Ijonga umsebenzi wevalvuayisebenzi; ayifuni lawulo lwesandla okanye lwangaphandle. Ukuhamba ngokwako kuvula ivalvu. Xa ukuhamba kuma okanye kubuyela umva, indlela yangaphakathi (idiski, ibhola, okanye idiaphragm) ivala ngokuzenzekelayo ngokusebenzisa amandla ombane, amandla entwasahlobo, okanye uxinzelelo lwangasemva.

Iindidi eziqhelekileyo zeeValve zokujonga

•Ivalvu yokujonga ibhola: Isebenzisa ibhola edadayo ehlala ecaleni kwetywina ukuvimba ukuhamba okungasemva. Ilula kwaye isebenza kwiindlela ezahlukeneyo zokusetyenziswa.

•Ivalvu yokujonga iSwing: Inesidiski esinamajikojiko esivuleka ngokugeleza kwaye sivaleleke kwisitywini xa ukugeleza kujika. Ixhaphakile emanzini nakwimigca yamanzi amdaka.

•Ivalvu yokujonga eFlanged: Ixhotyiswe ngeziphelo ezijijekileyo ukuze kuqhagamshelwe iibholiti kwiinkqubo zemibhobho ezinoxinzelelo oluphezulu okanye ezinkulu, ukuqinisekisa ukuba itywina eliqinileyo nelingenako ukuvuza.

•Ivalvu yokujonga enemisonto: Njengeevalvu zebhola ezinemisonto, ezi zenzelwe ukufakwa lula kwiinkqubo ezincinci.

Umahluko ophambili: Jonga iValve vs iValve yeBhola

Le theyibhile ishwankathela umahluko osisiseko phakathi kwevalvu yebhola kunye nevalvu yokujonga. 

*Ukutshixa ngevalvu yebhola eqhelekileyo akukhuthazwa kuba kunokubangela ukubola kwesisu kunye nokukhukuliseka kwesihlalo. Ivalvu yebhola ephawulweyo okanye i-V-port isetyenziselwa ukulawula.

Ingundoqoumahluko phakathi kwevalvu yebhola kunye nevalvu yokujongakukulawula ngokuchasene nokuzenzekela. Aivalvu yebholaimalunga nengqo, ulawulo olucwangcisiweyol yokuhamba. Aivalvu yokujongaimalunga nengokuzenzekelayo, ukhuseleko olungasebenziyoyenkqubo.

Izicelo kunye namatyala okusetyenziswa: Ukukhetha isixhobo esifanelekileyo somsebenzi

Apho Usebenzisa khona iValve yeBhola

•Ukubekwa wedwa:Ukuvala icandelo lombhobho ukuze kulungiswe.

•Ulawulo lweNkqubo:Njengevalvu yokuvula/yokucima ethembekileyo kuyo nayiphi na intambo yokucubungula.

•Ukusasazwa:Ukuqondisa ukuhamba kwamanzi kumasebe ahlukeneyo enkqubo.

•Ukhuseleko:Iindawo zokuvala ulwelo oluyingozi xa kukho imeko engxamisekileyo.

Apho Ufanele Usebenzise Ivalvu Yokujonga

•Ukhuseleko lweMpompo:Ifakwe kwicala lokukhupha amanzi kwimpompo ukuthintela ukubuya kwamanzi kunye nehamile yamanzi xa ipompo ima.

•Ukuthintela ukubuya komthamo:Ukuqinisekisa ukuba amanzi angcolileyo akabuyeli emanzini acocekileyo.

•Ukunyaniseka kwenkqubo:Ukugcina uxinzelelo emgceni kunye nokuthintela ukutsalwa kwamanzi (umz., kwiinkqubo ze-HVAC).

•Ukwahlulwa kweMidiya:Ukuthintela imidiya emibini eyahlukeneyo ukuba ingadibani kumgca ofanayo.

Ukufakela kunye nokulungisa Iindlela ezilungileyo zoKwenza

Jonga ukufakwa kweValve

Ukufakwa kwevalvu yokujonga ngokufanelekileyo kubalulekile ukuze isebenze ngokuchanekileyo.

1. Isikhokelo:Utolo olukwi-valve body kufuneka lukhombe kwicala elicetywayo lokuhamba kwamanzi.

2. Uqhelaniso:Iivalvu ezininzi zokujonga (ingakumbi iintlobo ze-swing) kufuneka zifakwe ngokuthe tye. Ezinye, njengeevalvu zokujonga ibhola, zinokusebenza kwimigca ethe nkqo enokuhamba okuphezulu. Soloko ujonga iinkcukacha zomenzi.

3. Iimvume zokurhoxiswa kwempahla:Qinisekisa ukuba umbhobho ujikeleziswa kakuhle ngaphambi nasemva kwevalvu ukuze idiski ijijeke kakuhle kwaye ijikeleze kakuhle.

Iingcebiso Zokulungisa Iivalvu Zebhola

Nangona ngokubanzi zingalungiswa kakhulu, iivalvu zebhola zemizi-mveliso ziyazuza ekuhlolweni rhoqo.

1. Ukukhwela ibhayisekile:Ziqhelise iivalvu rhoqo (zivule/zivale) ukuze zingabambeki, ingakumbi kwiinkqubo ezingasebenziyo.

2. Ukuhlolwa kokuvuza:Jonga ukuba izitywini zesiqu nezesihlalo azivuzi na.

3. Ukuhlolwa kwe-Actuator:Kwiivalvu zebhola ezizenzekelayo, qinisekisa umthombo wamandla we-actuator, iiswitshi zomda, kunye noseto lwe-torque.

4. Ukuthambisa:Ezinye iivalvu zifuna ukuthambisa isiqu rhoqo ngokusebenzisa igrisi.

Isiphelo: Ngumcimbi woMsebenzi, hayi ukhetho

Ukukhetha phakathi kwevalvu yebhola kunye nevalvu yokujonga akusiyonto yokuba yeyiphi engcono, kodwa yeyiphi efanelekileyo kulo msebenzi. Zenzelwe iinjongo ezahlukeneyo ngokupheleleyo.

• Khetha iValvu yeBholaxa udingaulawulo olusebenzayo, olwenziwa ngesandla, okanye oluzenzekelayoukuqala okanye ukuyeka ukuhamba kwamanzi.

• Khetha iValvu yokujongaxa udingaukhuseleko oluzenzekelayo, olungasebenziyoukuthintela ukuhamba okungasemva.

Kwiinkqubo ezintsonkothileyo, kuqhelekile ukuzibona zisebenza ngaxeshanye—umzekelo,ivalvu yebholaukuze umntu abe yedwa kwayeivalvu yokujongangoko nangoko phantsi kwepompo yokukhusela. Ngokuqonda iindima zabo ezahlukeneyo, ungazichaza iivalvu ngokuzithemba, uqinisekise ukusebenza kakuhle kwenkqubo, ukhuseleko, kunye nobude bayo.

Ngaba ukulungele ukucacisa ivalvu efanelekileyo yeprojekthi yakho? Khangela ikhathalogu ebanzi ye-NSW yokusebenza okuphezuluiivalvu zebhola zentsimbi engagqwaliyokwaye ithembekileiivalvu zokujongaukuze ufumane isisombululo esifanelekileyo kwisicelo sakho.
