Indlela Yokugcina Nokugcina Iivalvu Zesango Eligciniweyo Ngokufanelekileyo: Isikhokelo Seengcali

Yintoni iValve yeSango

A ivalvu yesangoilawula ukuhamba kolwelo ngokuphakamisa okanye ukuhlisa isango ngokuthe nkqo (i-wedge). Yenzelweimisebenzi epheleleyo yokuvula/yokuvala– ayilulo ulawulo lokuhamba kwamanzi – inika ukumelana okuncinci kokuhamba kwamanzi kunye nokuvala okuphezulu. Isetyenziswa kakhulu kwioyile/igesi, kwizityalo zeekhemikhali, nasekuveliseni umbane, ukuthembeka kwayo kwenza ukuba ibe yimfuneko kwiinkqubo zokugcina amanzi.

Umgaqo-nkqubo Wokusebenza weValve yeSango

Isango lihamba ngokuthe nkqo ukuya kumanzi. Xa liphakanyisiwe ngokupheleleyo, livumela ukuhamba okungenamkhawulo; xa lihlisiwe, lenza isitywino esiqinileyo nxamnye nezihlalo zevalvu.Ungaze uvuleke kancinciiivalvu zesango – oku kubangela ukukhukuliseka kwetywina kunye nomonakalo wokungcangcazela.

Amanyathelo ama-5 abalulekileyo okugcina iiValvu zeSango

Ukugcinwa kakuhle kuthintela ukugqwala kwaye kuqinisekisa ukuba iivalvu zokuxhasa ziyasebenza xa kufuneka.

1. Indawo efanelekileyo yokugcina izinto

–Ngaphakathi & Komile: Gcina kwiindawo ezivaliweyo, ezingenamanzi aneleyo (<60% RH).

–Ziphephe Izinto Ezidla Ukonakala: Gcina kude neekhemikhali, ityuwa, okanye umsi oneasidi.

–Ulawulo lobushushu: Gcina iqondo lobushushu liyi-5°C–40°C (41°F–104°F).(Jonga umgangatho we-ISO 5208: Ukufuma okugqithisileyo kunokukhokelela ngokulula ekugqwetheni kweendawo zesinyithi kunye nokuguga kwezivali zerabha.)

- Iivalvu ezinkulu nezincinci kufuneka zigcinwe ngokwahlukeneyo:Iivalvu ezincinci zingafakwa kwiishelufu, kwaye iivalvu ezinkulu mazibekwe kakuhle kumgangatho wendlu yokugcina impahla, ngelixa kuqinisekiswa ukuba umphezulu woqhagamshelo lweflange awuchukumisi umhlaba.

- Ukugcina iivalvu ngaphandle:Qiniseka ukuba uzigquma ngezinto ezingangeni mvula nezingenathuli, ezifana ne-tarpaulin, i-linoleum, njl. (Ukuba imeko iyavuma, kucetyiswa ukuba ungazigcini ngaphandle)

Iingcebiso:Gcina ivalvu yesango ngaphakathi kwaye ugcine igumbi lomile kwaye linomoya.

2. Ukulungiswa kweValve

–Vala iSango: Ithintela ukungena kothuli.

–IiPorts zokuTywinaSebenzisa izigqubuthelo zePVC okanye iiplagi ezigqunywe ngewax kwiiflanges.

–Lubricate Iziqu: Faka igrisi esemgangathweni ophezulu kwiziqu eziveziweyo.

Iingcebiso:Zombini iziphelo zendlela kufuneka zivalwe ngephepha le-wax okanye amaphepha eplastiki ukuthintela ukungcola ukuba kungangeni.

3. Iprotokholi Yokugcina Ixesha Elide

–Uhlolo lwekota: Jonga ukuba akukho mhlwa, ukuqina kwesigqubuthelo, kunye nokuthambisa.

–Jikelezisa amavili esandlaJika i-90° rhoqo emva kweenyanga ezi-3 ukuze uthintele ukubanjwa.

–Amaxwebhu: Iivalvu zethegi ezinemihla yokugcina kunye neengxelo zokuhlolwa.

- Unyango lokulwa nomhlwa:

1. Iivalvu zesinyithi (ezifana neevalvu zesango kunye neevalvu zokumisa) kufuneka zigqunywe ngeoyile okanye igrisi yokulwa nomhlwa, ingakumbi iindawo zeflange, iindawo ezidityanisiweyo kunye nezinye iindawo ezicoleka lula.

2. Xa igcinwe ixesha elide (ngaphezulu kweenyanga ezi-6), kuyacetyiswa ukuba ujonge kwaye wongeze i-anti-rust agent kwiinyanga ezi-3 (ngokwemigangatho ye-API 598).

4. I-Valve yeSango yeNtsimbi engenasici kunye neCarbon eyahlukileyo

- Umngcipheko Wokugqwala KweGalvanic:

1. Uqhagamshelwano + ukufuma kudala iseli ye-electrochemical.

2. Intsimbi yekhabhoni iba yi-anode, ibola ngokukhawuleza.

3. Intsimbi engatyiwayo (i-cathode) yonakele umaleko wayo okhuselayo, nto leyo ekhawulezisa ukugqwala kwixesha elizayo.

- Ukufuduka kweCarbon (iCarburization):

1. Ukudibana ngqo kuvumela iiathom zekhabhoni ukuba zisuke kwintsimbi yekhabhoni ziye kwintsimbi engatyiwayo.

2. Oku kuphazamisa ulwakhiwo lwentsimbi engagqwaliyo, kunciphisa kakhulu ukumelana kwayo nokugqwala.

- Iindlela ezilungileyo zokugcina izinto:

1. Indawo yokugcina eyahlukileyo: Gcina rhoqo kwiindawo ezahlukeneyo.

2. Umgama Omncinci: Gcina ubuncinane umgama ongama-50 cm (20 inches), ingakumbi kwiindawo ezinomswakama.

3. Ukudibana okwethutyana: Sebenzisa izithintelo ezomileyo, ezingahambisi zintambo (umthi, iplastiki, irabha) okanye izinto zokukhusela.

5. Imithetho Ebalulekileyo Yokwenza Ugcino Lweevalvu Lusebenze Kakuhle

- Ukuchongwa kokubhala ikhowudi yombala

• Iivalvu zentsimbi engatyiwayo → Iteyiphu eluhlaza okwesibhakabhaka

• Iivalvu zentsimbi yekhabhoni → Iteyiphu etyheli

Ithintela iimpazamo zolawulo lokubona kunye nokugqwala kwe-galvanic.

- Indawo yokugcina impahla yeFIFO

• Iindawo zokugcina ezinikezelweyo zivumela ukujikeleza kwe-First-In-First-Out

• Iphelisa ukuphelelwa lixesha kwesitokhwe (ibalulekile kwiivalvu zokuxhasa)

- Ukwahlulwahlulwa kweendleko

• Hlukanisa iivalvu zentsimbi engagqwaliyo (zixabisa ngaphezulu ngokuphindwe kathathu ukuya kahlanu)

• Ithintela ukusetyenziswa gwenxa ngengozi kunye nomonakalo wokugqwala

- Ukuphunyezwa koBunjineli

• Inkcazo yeNdlela

• Isithuba seendawo zokulala esiphakathi kweendawo ezingaphantsi komhlaba ezingama-≥500mm

• Iiphedi zerabha ezingasebenzisi umbane ze-8-10mm zokuzihlukanisa nge-electrochemical

*Ukuthobela: Ihlangabezana nemigangatho ye-GB/T 20878-2017.*

Iingcebiso ezibalulekileyo zobungcali

• Iindidi zezinto ezikrolwa nge-laser (umz., “i-WCB”) kwimizimba yeevalvu

• Gcina i-RH engaphantsi kwe-45% kwiindawo zokugcina

• Gcina iivalvu zesango elingasemva zimi nkqo - ukupakishwa ngokuthe tye kuthintela ukutywinwa okungxamisekileyo

Ukuthelekiswa kweendlela zokugcina iValve yeSango lokuGcina

Ukugcinwa kweValve yeSango: Iinkqubo ezi-4 eziphambili

1. Ukhathalelo lweMisebenzi oluQhelekileyo

–Lubricate Imisonto: Faka intlama ye-molybdenum disulfide kwiinkuni zesiqu rhoqo ngekota.

–Ingaphandle ecocekileyo: Sula ukungcola/inkunkuma nyanga zonke ngelaphu elingagugiyo.

–Jonga amavili esandla: Qinisa iibholithi ezikhululekileyo ngoko nangoko ukuze uphephe ukungalungelelani kakuhle.

2. Ukupakisha/Ukugcinwa kweGland

–Hlola rhoqo ngekota: Khangela ukuvuza okujikeleze isiqu.

–Lungisa iiNkozo zeGland: Qinisa kancinci kancinci ukuba kukho ukulila –musa ukucinezela kakhulu.

–Buyisela ukupakisha kwakhonaSebenzisa intambo efakwe igrafayithi rhoqo emva kweminyaka emi-2-5.

3. Iindlela ezilungileyo zokuthambisa

4. Ukhathalelo lweNkqubo yoThumelo

–Iibhokisi zegiyaTshintsha ioyile minyaka le (kucetyiswa i-ISO VG 220).

–Izixhobo zombane: Jonga izitywini zomswakama kabini ngonyaka.

–Ukubhalwa ngaphezulu ngesandla: Bhalisa ibhayisekile nyanga zonke ukuze uthintele ukuxhuzula.

Iingcebiso ezikhethekileyo zeeValve zoLondolozo

–Ukukhululeka kuxinzelelo: Vula iiplagi zokukhupha amanzi ngaphambi kokuba uthambise ukuze ungaphumi amanzi.

–Indawo yokuma: Iivalvu zesango lokugcinaivaliwe ngokupheleleyoukugcina izitywina zibambekile.

–Iikhithi zoNgxamiseko: Gcina izixhobo zokupakisha ezingasetyenziswanga kunye neenkozo zegland kufutshane.

Isiphelo: Ukwandisa Ubomi beValve

Landela le mithetho ukuze ufumane iivalvu zesango ezithembekileyo:

1. Indawo yokugcina izinto= Yomile, itywiniwe, kwaye ibhalwe phantsi.

2. Ulondolozo= Ukuthambisa okucwangcisiweyo kunye nokuhlolwa.

3. Ukulungiswa= Lungisa ukuvuza ngokukhawuleza.

Ngokubeka phambili ukhathalelo olusebenzayo, uphepha ama-80% okungasebenzi kakuhle kweevalvu - okubaluleke kakhulu kwiinkqubo zongxamiseko.
