1. Intshayelelo
Ukutshintsha izitywina zerabha kwiivalvu zebhabhathane yinkqubo entsonkothileyo efuna ulwazi lobugcisa, ukuchaneka, kunye nezixhobo ezifanelekileyo zokuqinisekisa ukusebenza kwevalve kunye nokutywinwa kwengqibelelo kuhlala kunjalo. Esi sikhokelo esinzulu kwiingcali zogcino lwevalvu kunye namagcisa abonelela ngemiyalelo eneenkcukacha, iindlela ezingcono, kunye neengcebiso zokusombulula ingxaki.
Ukugcina izihlalo zevalve yebhabhathane kubalulekile ukuqinisekisa ukuba ziphila ixesha elide kunye nokusebenza kakuhle. Nangona kunjalo, ngokuhamba kwexesha, izitywina zerabha kwiivalve zebhabhathane zinokwehla ngenxa yezinto ezinje ngoxinzelelo, ubushushu, kunye nokuvezwa kweekhemikhali. Ke ngoko, izihlalo zevalvu zifuna ukugcinwa rhoqo ukuthintela ukungaphumeleli kunye nokwandisa ubomi bala macandelo abalulekileyo.
Ukongeza kwi-lubrication, ukuhlolwa, kunye nokulungiswa kwangexesha ukuze bahlale bekwimeko efanelekileyo, ukutshintshwa kwetywina zerabha kunenzuzo ebalulekileyo. Yandisa ukusebenza kakuhle kwevalve ngokuthintela ukuvuza kunye nokuqinisekisa ukutywinwa okuqinileyo, ukunciphisa ixesha lokuphumla kunye nokuphucula ukuthembeka okupheleleyo.
Esi sikhokelo sibandakanya yonke inkqubo ukusuka kulungiselelo lokutshintshwa kwesihlalo ukuya kuvavanyo lokugqibela, kwaye sibonelela ngamanyathelo abanzi kunye nezilumkiso.
2. Ukuqonda iivalve zebhabhathane kunye nezitywina zerabha
2.1. Ukuqulunqwa kweevalve zebhabhathane
Iivalve zebhabhathane zenziwe ngamalungu amahlanu: umzimba wevalvu,ipleyiti yevalvu, ishafu yevalvu,isihlalo sevalve, kunye ne actuator. Njengesixhobo sokutywina sevalve yebhabhathane, isitulo sevalve sihlala sibekwe kufutshane nediski yevalvu okanye umzimba wevalvu ukuqinisekisa ukuba ulwelo aluphumi xa ivalve ivaliwe, ngalo ndlela igcina itywina eliqinileyo, elingavuziyo.
2.2. Iintlobo zezihlalo zevalve yebhabhathane
Izihlalo zevalve yebhabhathane zinokwahlulwa zibe ziindidi ezi-3.
2.2.1 Isitulo sevalve ethambileyo, ekubhekiselelwe kuso isitulo sevalvu enokushintshwa esikhankanywe kweli nqaku.
I-EPDM (i-ethylene propylene diene monomer rubber): ukumelana namanzi kunye neekhemikhali ezininzi, ezifanelekileyo kunyango lwamanzi.
- I-NBR (i-rubber ye-nitrile): ilungele ukusetyenziswa kweoli kunye negesi ngenxa yokuchasana kweoli.
- Viton: ingasetyenziswa kwizicelo zobushushu obuphezulu ngenxa yokumelana nobushushu.
2.2.2 I-backrest enzima, olu hlobo lwesitulo sevalve lunokutshintshwa, kodwa lunzima ngakumbi. Ndiza kubhala elinye inqaku ukulichaza ngokweenkcukacha.
2.2.3 Isitulo sevalve evulcanized, esisisihlalo sevalvu engenakutshintshwa.
2.3 Iimpawu ezibonisa ukuba irubber seal ifuna ukutshintshwa
- Ukunxitywa okubonakalayo okanye umonakalo: Ukuhlolwa komzimba kunokutyhila iintanda, iinyembezi, okanye ukonakala kwetywina.
- Ukuvuza okujikeleze ivalve: Nakwindawo evaliweyo, ukuba ulwelo luyavuza, isitywini sinokunxitywa.
- Ukonyuka kwetorque yokusebenza: Ukonakala kwesitulo sevalve kuya kubangela ukonyuka kokusebenza kwevalve yebhabhathane.
3. Ukulungiselela
3.1 Izixhobo kunye nezixhobo ezifunekayo
Ukutshintsha ngokufanelekileyo isitywina serubha kwivalve yebhabhathane, izixhobo ezithile kunye nezinto eziyimfuneko. Ukuba nezixhobo ezifanelekileyo kuqinisekisa inkqubo egudileyo nenempumelelo yokutshintshwa.
- Izikrweqe, ii-screwdrivers, okanye i-hexagon sockets: Ezi zixhobo zikhulula kwaye ziqinise iibholiti ngexesha lokutshintshwa. . Qinisekisa ukuba uneseti yee-wrenches ezihlengahlengiswayo, izikrufu ze-slotted kunye ne-Phillips, kunye nobukhulu obahlukeneyo beesokethi zehexagon ukulungiselela ubungakanani obahlukeneyo beebholiti.
- I-Lubricants: I-Lubricants, njenge-silicone grease, idlala indima ebalulekileyo ekugcineni iindawo ezihambayo zevalve. Ukusebenzisa isithambiso esifanelekileyo kunciphisa ukukhuhlane kwaye kuthintela ukuguga.
- Isando zerabha okanye isando somthi: Yenza isitulo silingane ngokuthe nkqi kumzimba wevalvu.
- Isitulo esitsha sevalve: Isitywina esitsha serabha sibalulekile kwinkqubo yokutshintshwa. Qinisekisa ukuba isitywina sidibana neenkcukacha zevalvu kunye neemeko zokusebenza. Ukusebenzisa izitywina ezihambelanayo kuqinisekisa ukulingana okuqinileyo kunye nokusebenza kakuhle.
-Izixhobo zokucoca: Coca umphezulu wokutywina ngokucokisekileyo ukuze ususe nayiphi na inkunkuma okanye intsalela. Eli nyathelo liqinisekisa ukuba isihlalo esitsha sifakwe ngokuchanekileyo kwaye sithintela ukuvuza emva kokufakwa.
-Iiglavu ezikhuselayo kunye nezibuko: Qinisekisa ukhuseleko lwabasebenzi.
3.2 Lungiselela ukutshintshwa
3.2.1 Vala isixokelelwano sombhobho
Phambi kokuba uqalise ukutshintsha isihlalo serabha kwivalve yebhabhathane, qiniseka ukuba isixokelelwano sivaleke ngokupheleleyo, ubuncinci ivalve engasentla kwevalve yebhabhathane ivaliwe, ukukhulula uxinzelelo kunye nokuqinisekisa ukuba akukho manzi aphumayo. Qinisekisa ukuba icandelo lombhobho licinezelwe ngokujonga i-gauge yoxinzelelo.
3.2.2 Nxiba izixhobo zokukhusela
Ukhuseleko kufuneka lusoloko luphambili kuwe. Nxiba izixhobo ezifanelekileyo zokukhusela, kuquka iiglavu kunye neeglavu. Ezi zinto zithintela iingozi ezinokubakho ezifana nokutshiza kweekhemikhali okanye imiphetho ebukhali.
4. Faka endaweni yesitywina serabha kwivalve yebhabhathane
Ukutshintsha isitywina serabha kwi-aivelufa butterflyyinkqubo elula kodwa eethe-ethe efuna ingqalelo kwiinkcukacha. Landela la manyathelo angezantsi ukuqinisekisa ukutshintshwa okuyimpumelelo.
4.1 Uzahlula njani ivalve yebhabhathane?

Sebenzisa isikrufu ukukhulula iibholithi okanye izikrufu ezikhusela ukudityaniswa kwevalvu. Susa ezi zibophelelo ngononophelo ukuphepha ukonakalisa umzimba wevalvu.
4.1.3. Susa iValve yeButterfly
Khupha ngononophelo ivalve ngaphandle kombhobho, uxhasa ubunzima bayo ukuthintela umonakalo kumzimba wevalve okanye idiski.
4.1.4 Nciphisa i-actuator
Ukuba i-actuator okanye isiphatho siqhagamshelene, yikhuphe ukuze ufikelele ngokupheleleyo kumzimba wevalvu.
4.2 Susa isitulo esidala sevalvu
4.2.1. Susa itywina:
Hlukanisa indibano yevalvu kwaye ususe ngononophelo itywina elidala lerabha.
Ukuba kuyimfuneko, sebenzisa isixhobo esiluncedo esifana ne-screwdriver ukuze uvale isitywina, kodwa qaphela ukuba ungakrweli okanye uwonakalise indawo yokutywina.
4.2.2. Jonga ivalve
Emva kokususa itywina elidala, hlola umzimba wevalvu ukubona iimpawu zokuguga okanye ukonakala. Olu hlolo luqinisekisa ukuba isitywina esitsha sifakwe ngokuchanekileyo kwaye sisebenza ngokufanelekileyo.
4.3 Fakela itywina elitsha
4.3.1 Coca umphezulu
Ngaphambi kokufaka isitywina esitsha, coca indawo yokutywina kakuhle. Susa nayiphi na inkunkuma okanye intsalela ukuqinisekisa ukulingana okuqinileyo. Eli nyathelo libalulekile ekuthinteleni ukuvuza kunye nokuqinisekisa ukusebenza kakuhle.
4.3.2. Hlanganisa isitulo sevalve
Beka isihlalo sevalve entsha endaweni, uqinisekise ukuba ukuvuleka kwayo kuhambelana ngokufanelekileyo nokuvuleka komzimba wevalve.
4.3.3 Hlanganisa kwakhona ivalve
Hlanganisa ivalve yebhabhathane ngokulandelelana kwe-disassembly. Ukulungelelanisa iinxalenye ngononophelo ukuphepha ukungahambi kakuhle, okunokuchaphazela ukusebenza kwesitywina.
4.4 Ukuhlolwa kwasemva kokutshintshwa
Emva kokutshintsha isihlalo sevalve yebhabhathane, ukuhlolwa kwe-post-replacement kuqinisekisa ukuba i-valve isebenza ngokufanelekileyo nangempumelelo.
4.4.1. Ukuvula kunye nokuvala ivalve
Sebenzisa ivalve ngokuyivula kwaye uyivale amaxesha amaninzi. Lo msebenzi uqinisekisa ukuba isitywina esitsha sesivalo sihleli ngokufanelekileyo. Ukuba kukho ukuchasana okungaqhelekanga okanye ingxolo, oku kungabonisa ingxaki kwindibano.
4.4.2. Uvavanyo loxinzelelo
Ukwenza uvavanyo loxinzelelo yinyathelo elifunekayo ngaphambi kokuba i-valve ye-butterfly ifakwe ukuqinisekisa ukuba i-valve inokumelana noxinzelelo lokusebenza kwenkqubo. Olu vavanyo lukunceda ukuba uqinisekise ukuba itywina elitsha libonelela ngesitywina esiqinileyo nesithembekileyo ukuthintela nakuphi na ukuvuza okunokwenzeka.
Jonga indawo yokutywina:
Jonga indawo ejikeleze itywina elitsha ukubona iimpawu zokuvuza. Jonga amathontsi okanye ukufuma okunokuthi kubonise ukungatywinwa kakuhle. Ukuba kukho nakuphi na ukuvuza kufunyenwe, kunokufuneka uhlengahlengise isitywini okanye uqinise kwakhona uqhagamshelwano.
4.5 Fakela ivalve yebhabhathane
Qinisa iibholithi okanye izikrufu usebenzisa isikrufu. Qinisekisa ukuba zonke iindibano ziqinile ukuthintela nakuphi na ukuvuza. Eli nyathelo ligqiba inkqubo yokufakela kwaye lilungiselela ukuvavanya ivalve.
