Isebenza Njani Ivalvu Yebhola: Isikhokelo Esipheleleyo -Ivalvu yeNSW

Intshayelelo: Icandelo Elibalulekileyo Kwiinkqubo Zolwelo

Ivalvu yebhola isebenza ngokujikeleza ibhola elingqukuva elinomngxuma ogqojoziweyo ukulawula ukuhamba kolwelo.Xa imbobo ihambelana nombhobho, ivalvu ivulekile; xa ijikeleziswa ngama-90 degrees, inxalenye eqinileyo yebhola iyayivala indlela ephuma ngayo, nto leyo evumela ukuvalwa okuqinileyo kunye nokwehla koxinzelelo oluncinci.

Ukuqonda indlela esebenza ngayo ivalvu yebhola kubalulekile kwiinjineli, amaqela olondolozo, kunye neengcali zokuthenga ezibandakanyeka kwiinkqubo zamanzi zoshishino.iivalvu zebholazihlala zibonwa njengezixhobo ezilula zokuvula/ukucima, uyilo lwangaphakathi, izixhobo, kunye noqwalaselo lwazo luchaphazela ngokuthe ngqo ukhuseleko lokusebenza, ukusebenza kakuhle, kunye neendleko zizonke zobunini.

Esi sikhokelo sidlula ngaphaya kwengcaciso esisiseko. Sidibanisaingqiqo yobugcisa kwinqanaba lobunjinelikunyeiingqwalasela zokufumana ulwazi olusebenzayo kunye nomjikelo wobomi, ukunceda iinjineli kunye nabathengi ukuba benze izigqibo ezinolwazi.

Isebenza Njani Ivalvu Yebhola? (Icacisiwe Indlela Yokusebenza)

Ivalvu yebhola isebenza kwiumgaqo wokusebenza wekota-turn:

1. Indawo evulekileyo
   Xa isiphatho okanye i-actuator ihambelana nombhobho, umngxuma wangaphakathi webhola uhambelana nendlela yokuhamba kwamanzi. Ulwelo ludlula ngaphandle kokuxinana okuncinci kunye nokulahlekelwa koxinzelelo.

2. Indawo eValiweyo
   Ukujikeleza isiphatho okanye i-actuator ngama-90 degrees kujika ibhola ukuze icala layo eliqinileyo livale ukuhamba. Isihlalo esisezantsi sicinezelwa ngokuqinileyo kwibhola luxinzelelo lwenkqubo, nto leyo edalaisitywino esincediswa luxinzelelo.

Ingcaciso yoBunjineli:
I-torque yokusebenza yeivalvu yebholaayihlali injalo. I-torque ephezulu yenzeka ngexesha lokuqhekeka kokuqala ("i-torque yokuyeka ukusebenza"). Amaxabiso e-torque achanekileyo anikezelwa ngumvelisi abalulekile kubungakanani obuchanekileyo be-actuator kunye nokuthembeka kwexesha elide.

Isikhokelo soYilo kunye noKhetho lweeValve zeBhola kwiZicelo zoShishino

Ukuthembeka kwevalvu yebhola kuvela kuyilo lwayo oluqinileyo loomatshini, kodwa ukusebenza kuyahluka kakhulu kuxhomekeke kwiinkcukacha zokwakha kunye nokukhethwa kwezinto.

Izinto eziBalulekileyo kunye nezinto eziqwalaselwayo

Umzimba weValve

Umzimba usebenza njengeyona nto iphambili yokugcina uxinzelelo. Izinto eziqhelekileyo ziquka intsimbi yekhabhoni (i-WCB), intsimbi engatyiwayo (316), kunye nentsimbi engatyiwayo ephindwe kabini. Ukukhethwa kuxhomekeke kudidi loxinzelelo, ubushushu, ukumelana nokugqwala, kunye nexabiso.

Inqaku lokufumana ulwazi:
Soloko uqinisekisa iZatifikethi zoVavanyo lweMpahla (iiMTC) ngokuhambelana nemigangatho ye-ASME okanye ye-ASTM.

Ibhola

Ibhola inesivalo sokuhamba kwaye iyajikeleza ukulawula ukuhamba. Ukugqitywa komphezulu kunye neengubo ezifana ne-chrome plating eqinileyo okanye i-ceramic coating ziphucula ukumelana nokuguguleka kwaye zinciphise ukurhawuzelelwa.

Kwizicelo zolawulo,Iibhola ze-V-portibonelela ngokuchaneka okuphuculweyo kokugoba xa kuthelekiswa noyilo oluqhelekileyo lwezibuko ezijikelezayo.

Izihlalo

Izihlalo zenza uphawu phakathi kwebhola kunye nomzimba wevalvu. Izixhobo eziqhelekileyo zesihlalo ziquka:

• I-PTFE / i-RPTFE:Ukungqubana okuphantsi, okufanelekileyo kwiinkonzo ezininzi

• Iipolymers zePEEK kunye neziphambili:Kwamaqondo obushushu aphezulu kunye noxinzelelo

• Izihlalo zesinyithi:Iyimfuneko kwiinkonzo ezirhabaxa okanye ezishushu kakhulu

Iivalvu zebhola ezikhuselekileyo emlilweni kufuneka zihambelaneI-API 607 ​​okanye i-ISO 10497imigangatho.

Isiqu

Isiqu sidlulisela i-torque ukusuka kwi-actuator ukuya ebholeni.isiqu esithintela ukuvuthulukaluphawu olubalulekileyo lokhuseleko. Ukupakisha igrafiti enezandi ezininzi kunye nezipringi ezithwala izinto eziphilayo kuqinisekisa ukuvalwa kwexesha elide kunye nokunciphisa ukukhutshwa komoya ophumayo.

Iintlobo zeeValve zeBhola: iPort epheleleyo, iPort encitshisiweyo, kunye neTrunnion efakwe

Ukukhetha uhlobo lwevalvu yebhola oluchanekileyo sesinye sezona zigqibo zibalulekileyo kwezobugcisa nezorhwebo.

Inqaku loBunjineli:
Iivalvu zebhola ezifakwe kwiTrunnionIxhasa ibhola kuzo zombini iziphelo, inciphisa umthwalo wesihlalo kunye ne-torque yokusebenza, nto leyo eyenza ukuba ilungele ukusetyenziswa kweClass 600+ kunye nobukhulu obukhulu.

Izicelo zeValve yeBhola eqhelekileyo

Ngenxa yokuvalwa kwazo ngokuqinileyo, ukusebenza ngokukhawuleza, kunye neemfuno zokugcinwa eziphantsi, iivalvu zebhola zisetyenziswa kakhulu kumacandelo emizi-mveliso:

• Imibhobho yeoyile negesi

• Ukucubungula iikhemikhali kunye ne-petrochemical

• Unyango lwamanzi kunye nokukhupha ityuwa emanzini

• Iinkqubo zokuvelisa umbane

• Ukutya, iziselo, kunye nokulungiswa kwamayeza (iivalvu zebhola yococeko)

Uyilo olufanelekileyo lwevalvu yebhola luxhomekekeuhlobo lwemidiya, uxinzelelo, ubushushu, ubuninzi bomjikelo, kunye neemfuno zokhuseleko.

Iivalvu zeBhola ezenziwe ngesandla nezizenzekelayo

Iivalvu zeBhola ezenziwe ngesandla

Iivalvu zebhola ezisebenza ngesandla zisebenzisa izibambo ze-lever okanye ii-gearbox. Zilula, zingabizi kakhulu, kwaye zifanelekile ukusetyenziswa rhoqo.

Iivalvu zeBhola eziZenzekelayo

Iivalvu zebhola ezizenzekelayo zisebenzisa ii-actuators zombane, ze-pneumatic, okanye ze-hydraulic ekusebenzeni kude okanye rhoqo.

Ingcebiso yokuthenga:
Qinisekisa ukuba ivalvu kunye ne-actuator mounting interface ziyahambelana, ngokwesiqhelo ngokweI-ISO 5211imigangatho.

Iivalvu zeBhola ezikhethekileyo zeMisebenzi ethile

• Iivalvu zeBhola ze-V-Port:Yenzelwe ukulawula ukuhamba kwamanzi kunye nokugoba

• Iivalvu zeBhola ezineZibuko ezininzi (iindlela ezi-3 / iindlela ezi-4):Isetyenziselwa ukujika, ukuxuba, okanye ukutshintsha indlela yokuhamba

• Iivalvu zeBhola eziKhutshwayo (LE) eziphantsi:Yenzelwe ukunciphisa ukukhutshwa komoya ongcolileyo kwaye ithobela i-ISO 15848

Kwizicelo ezikhupha ukungcola okuncinci, iingxelo zovavanyo eziqinisekisiweyo kufuneka zihlale zifuneka ngexesha lokufumana imveliso.

Ingqwalasela yeendleko zokufakelwa, ukugcinwa, kunye nomjikelo wobomi

Iindlela ezilungileyo zokufaka

1. Hlukanisa kwaye unciphise uxinzelelo lombhobho ngaphambi kokufakwa

2. Qinisekisa ukulungelelaniswa kweflegi ngokufanelekileyo ngaphandle kokunyanzela

3. Ngexesha lokuwelda, khusela izihlalo zangaphakathi kubushushu obugqithisileyo

4. Sebenzisa izigqubuthelo zokukhusela xa uthutha kwaye ugcina

Ukugcinwa kunye nokusombulula iingxaki

• Jikelezisa iivalvu rhoqo ukuze unganamatheli

• Hlola ukupakisha isiqu kunye nezitywino zomzimba ukuze ubone ukuba azinawo na umonakalo wangaphandle

• Ukuvuza kwangaphakathi kudla ngokubonisa umonakalo wesihlalo okanye ibhola

• Gcina iindawo ezibalulekileyo zeevalvu ezibaluleke kakhulu

Uhlalutyo lweendleko zomjikelo wobomi: Ngaphaya kwexabiso lokuqala

Ngokwembono yokuthengwa, ukhetho lweevalvu zebhola kufuneka lusekelweIxabiso lilonke lobunini (i-TCO)endaweni yexabiso leyunithi yodwa:

1. Iindleko zokufumana:Ivalvu, i-actuator, izixhobo

2. Iindleko zokufakela:Iphenjelelwa bubungakanani, ubunzima, kunye nobunzima

3. Iindleko Zokusebenza:Ukulahleka koxinzelelo, ukusetyenziswa kwamandla, ukugcinwa

4. Ixabiso loMngcipheko:Ixesha lokungasebenzi, izehlo zokhuseleko, kunye nemiphumo yokungaphumeleli

Isiphelo: Ukulungelelanisa iiMfuno zoBunjineli kunye neCandelo loBuchule

Iivalvu zebholaingabonakala ilula, kodwa ukusebenza kwayo kubangelwa bubunjineli obucokisekileyo kunye nokukhetha okunolwazi. Iinjineli kufuneka zichaze ngokucacileyo iimeko zokusebenza, ngelixa abathengi kufuneka bavavanye ixabiso lexesha elide besebenzisa uhlalutyo lweendleko zomjikelo wobomi.

Njengoko iinkqubo zoshishino zitshintsha,iivalvu zebhola ezikrelekrele nezisebenza ngesensorziya zisiba zibaluleke ngakumbi kulondolozo oluqikelelweyo kunye nokuhlanganiswa kwedijithali.

Ngokudibanisa ukuqonda okuqinileyo kwendlela esebenza ngayo ivalvu yebhola kunye neendlela zokufumana ulwazi oluchanekileyo, imibutho inokufezekisa imisebenzi ekhuselekileyo, ukuthembeka okuphuculweyo, kunye nembuyekezo ephezulu kutyalo-mali.
