Intshayelelo
Iivalvu zesango zizinto ezibalulekileyo kwiinkqubo zemibhobho yemizi-mveliso, zilawula ukuhamba kolwelo kunye neegesi. Nangona kunjalo, umngeni oqhelekileyo ojongene nabaqhubi nguloukulinganisa kwiivalvu zesango—into ebeka emngciphekweni ukusebenza kakuhle, ukhuseleko, kunye nobomi obude. Njengento ethembekileyoUmzi-mveliso wevalvu yesango laseTshayina, siyaqonda ukubaluleka kokujongana nale ngxaki. Kweli nqaku, siza kuhlola ukuba yintoni ukukala, iingozi zayo, izizathu eziphambili, kunye nendlela ubuchwepheshe obuphambili bokugquma obunokuyithintela ngayo. Siza kwabelana ngeengcebiso zeengcali ezivelaabavelisi beevalvu zesangokwaye ucacise umahluko phakathiivalvu yehlabathi vs ivalvu yesangoizicelo.
1. Yintoni i-Scaling kwi-Gate Valve
Ukulinganisa kubhekisa ekuqokeleleni kweediphozithi zeeminerali, ezifana necalcium carbonate, i-silica, okanye iisulfates, kwiindawo zeevalvu zesango. Ezi diphozithi zenzeka xa iiminerali ezinyibilikisiweyo kulwelo zinamathela kwaye zinamathela kwizixhobo zesinyithi, ingakumbi phantsi kobushushu obuphezulu okanye utshintsho loxinzelelo. Ngokuhamba kwexesha, ukulinganisa kudala umaleko oqinileyo noqhekekileyo ophazamisana nokusebenza kwevalvu.
Ngokubaiivalvu zesango, ukulinganisa kudla ngokujolisa kwiindawo ezibalulekileyo ezifana ne-wedge, isihlalo, kunye nesiqu.iivalvu zeglobhu(ezisebenzisa indlela yokuxhuma kunye nesihlalo), iivalvu zesango zixhomekeke kwisango elithe tyaba okanye elimile okwe-wedge ukulawula ukuhamba kwamanzi. Ukwandisa ubungakanani kwezi zinto kunokukhokelela ekuvalekeni okungaphelelanga okanye ekungqubaneni okwandileyo ngexesha lokusebenza.
2. Iingozi zokwandisa ubungakanani beeValve zeSango
Ukwandisa ubungakanani bomsebenzi kungaphezulu nje kwengxaki encinci—kubangela iingozi ezinkulu zokusebenza kunye nezemali:
- Ukusebenza kakuhle okunciphileyoIidiphozithi zithintela ukuhamba kolwelo, zinyanzela iinkqubo ukuba zisebenze nzima kwaye zonyusa ukusetyenziswa kwamandla.
- Ukuvuza: Ukwandisa ubungakanani besangqa kuthintela isango ukuba lingavaleki ngokupheleleyo, nto leyo ekhokelela ekuvuzeni kwamanzi kunye neengozi ezinokubakho kwindalo esingqongileyo.
- Ukukhawuleziswa koMhlwa: Iidiphozithi zibamba umswakama, zikhawulezisa ukugqwala ngaphantsi komaleko wesikali.
- Iindleko zoLondolozo ezinyukileyo: Ukucoca rhoqo okanye ukutshintshwa kwezixhobo kunyusa ixesha lokungasebenzi kunye neendleko.
- Iingozi zoKhuseleko: Kwiimeko ezigqithisileyo, ukungasebenzi kakuhle kweevalvu ngenxa yokusikwa kwe-scaling kunokubangela uxinzelelo olugqithisileyo okanye ukuvalwa kwenkqubo.
Kwimizi-mveliso efana neoyile negesi, ukucubungula iikhemikhali, okanye unyango lwamanzi, le mingcipheko ayamkelekanga. Yiyo loo nto ukukhokelaiifektri zevalvu yesangoukuthintela ukwanda komlinganiselo.
3. Kutheni Ukulinganisa Kwenzeka KwiiValve Zesango
Ukuqonda izizathu zokukhuliswa kwamanqanaba kubalulekile ekuthinteleni:
- Umgangatho Wamanzi: Amanzi aqinileyo aneeminerali ezininzi yeyona nto iphambili ebangela oku.
- Ukutshintshatshintsha kobushushu: Ubushushu okanye ulwelo olupholisayo lunokubangela ukuna kweeminerali.
- Isantya Sokuhamba OkuphantsiIimeko ezimileyo zivumela iiminerali ukuba zihlale kwiindawo zeevalvu.
- Ukuhambelana kwezinto: Iivalvu zentsimbi yekhabhoni okanye zentsimbi ezingagqunywanga zithandwa kakhulu kunentsimbi engagqwaliyo okanye ezinye iindlela ezigqunywe ngentsimbi.
- Ukugcinwa Okubi: Ukuhlolwa okungasoloko kuvumela iidipozithi ukuba ziqokeleleke zingabonwa.
Kuthelekiswa neiivalvu zeglobhu, ezijongana nokuqhobosheka kunye nokulungiswa rhoqo, iivalvu zesango zihlala zisetyenziswa kwizicelo zokuvula/ukuvala. Nangona kunjalo, zombini ezi ntlobo zeevalvu zisengozini yokukhuliswa ngaphandle kokhuseleko olufanelekileyo.
4. Indlela Yokuthintela Ukwanda KweeValvu Zesango
Amanyathelo asebenzayo anokunciphisa iingozi zokwandisa ubungakanani bemveliso:
- Unyango lwamanziSebenzisa izithambisi okanye izithinteli zeekhemikhali ukunciphisa umxholo weeminerali kulwelo.
- Ukugcinwa rhoqo: Hlela uhlolo kunye nokucoca ukuze kususwe iidiphozithi ezikwinqanaba lokuqala.
- Ukuphuculwa kwezinto: Khetha ii-alloys ezimelana nokugqwala ezifana nentsimbi engagqwaliyo okanye intsimbi ye-duplex.
- Uhlengahlengiso Lokusebenza: Gcina isantya sokuhamba kwamanzi esifanelekileyo ukuze kuncitshiswe ukungazinzi.
- Iingubo eziPhambili: Faka izinto ezikhethekileyo zokuthintela ukwakheka kweevalvu kwiindawo zeevalvu.
Phakathi kwezi zisombululo, iteknoloji yokugquma ibalasele ngokusebenza kwayo kakuhle kweendleko kunye nokusebenza kwayo ixesha elide.
5. Indlela Iingubo Ezithintela Ngayo Ukwanda KweeValvu Zesango
Iingubo zenza umqobo okhuselayo phakathi kwemiphezulu yeevalvu kunye nolwelo olutyebileyo kwiiminerali. Nantsi indlela ezisebenza ngayo:
- Umphezulu OnganamatheliyoIingubo ezifana ne-PTFE (Teflon) okanye i-epoxy zinciphisa uburhabaxa bomphezulu, nto leyo eyenza kube nzima ukuba iiminerali zinamathele.
- Ukumelana neekhemikhali: Ezinye iingubo ziyayithomalalisa i-ion esabelayo kulwelo, zithintela ukwakheka kwekristale.
- Uzinzo lobushushu: Iingubo ezishushu kakhulu zimelana nokujikeleza kobushushu ngaphandle kokuwohloka.
- Ukhuseleko lokugqwala: Ngokukhusela isinyithi kumswakama, iingubo zilwa nokugqwala kunye nokugqwala.
UkukhokelaIvalvu yesango laseTshayinaabavelisi basebenzisa iindlela eziphambili ezifana ne-plasma spray okanye i-electroless nickel plating ukufaka ii-coatings ezihlala ixesha elide nezifanayo. Umzekelo, i-umzi-mveliso wevalvu yesangoingasebenzisa i-HVOF (High-Velocity Oxygen Fuel) coating ukuze igqibele kakuhle kwiindawo ezigudileyo.
6. Iingcebiso zeengcali ezivela kubavelisi beevalvu zesango
Ukuze uqinise ukumelana nokukhula komlinganiselo, landela la macebiso avela kwiingcali zoshishino:
