Ufuna ivalve engayi kuvuza okanye yophuke, kodwa iPVC ibonakala inexabiso eliphantsi kwaye ilula. Ukukhetha indawo engeyiyo kunokuthetha iworkshop ezele zizikhukula kunye nexesha lokuphumla elineendleko.
Umgangatho ophezuluIivalvu zebhola zePVCzithembeke kakhulu kwizicelo ezijoliswe kuzo. Ukuthembeka kwabo kubangelwa kuyilo lwazo olulula kunye nokukhuseleka okupheleleyo kwi-rust kunye ne-corrosion, ezona ndawo zingaphumeleli kwiivalve zetsimbi kwiinkqubo ezininzi zamanzi.
Umbuzo wokuthembeka uvela ngalo lonke ixesha. Bendisandula ukuthetha noKapil Motwani, umanejala wokuthenga endisebenza naye eIndiya. Ubonelela ngezixhobo kumashishini amaninzi asebenza emanzini afuya iintlanzi neeshrimps ngaselunxwemeni. Bakhe basebenzisaiivalve zobhedu, kodwa amanzi etyuwa ahlala etshizwa kunye nomoya ofumileyo unokuwatshabalalisa kwisithuba esingaphantsi kweminyaka emibini. Izibambo ziya kubamba phezulu okanye imizimba iya kufumana ukuvuza komngxuma. Xa ezitshintshela kwiPntek yethuIivalvu zebhola zePVC, yaphela ingxaki. Kwiminyaka emihlanu, ezo zivalo zePVC zisebenza ngokugqibeleleyo. Olo luhlobo lokuthembeka olubalulekileyo kwihlabathi lokwenyani.
Ingaba ivalve yebhola yePVC iya kuhlala ixesha elingakanani?
Ufaka inkqubo kwaye kufuneka uthembele kumalungu ayo iminyaka. Ukukrazula rhoqo kwaye utshintshe iivalvu ezingaphumeleliyo yintloko enkulu kunye neendleko ofuna ukuziphepha.
Ivalve yebhola yePVC eyenziwe kakuhle inokuhlala iminyaka eyi-10 ukuya kwengama-20, okanye nangaphezulu kwiimeko ezifanelekileyo. Imiba ephambili emisela ubomi bayo bubulunga bemathiriyeli ye-PVC, ukuvezwa kwe-UV, ukuhambelana kweekhemikhali, kunye nokuphindaphinda kokusetyenziswa.
Ubude bevalve ayilonani elinye; sisiphumo esithe ngqo somgangatho kunye nokusetyenziswa kwayo. Eyona nto inkulu yimathiriyeli ngokwayo. Sisebenzisa kuphelaI-100% ye-PVC enyulu. Abavelisi abaninzi abancinci basebenzisa“regrind”—izilaphu zeplastiki ezisetyenzisiweyo-nto leyo eyazisa ukungcola kwaye yenza ukuba imveliso yokugqibela ibemnkum kwaye ithande ukusilela. Enye into ephambili kukukhanya kwelanga. I-PVC esemgangathweni iya kwenziwa buthathaka kukuvezwa kwexesha elide le-UV, yiyo loo nto sivelisa iinguqulelo ezixhathisa i-UV kwizicelo zangaphandle ezifana nokunkcenkceshela. Ekugqibeleni, qwalasela amatywina angaphakathi. Izivalo zethu zisebenzisa egudileyo, yomeleleIzihlalo ze-PTFEekwaziyo ukujongana namawaka emijikelo, ngelixa iivalvu zexabiso eliphantsi zihlala zisebenzisa irabha ethambileyo enokuthi ikrazuke okanye ithobeke ngokukhawuleza, ibangele ukuba ivalve ingavaleleki. Ivalve esemgangathweni ayiyonxalenye nje; lutyalo-mali lwexesha elide ekuthembekeni.
Izinto ezichaphazela uBomi beValve ye-PVC
| Umba | Umgangatho ophezulu (Ubomi obude) | Umgangatho ophantsi (Ubomi obufutshane) |
|---|---|---|
| Izinto zePVC | 100% Virgin PVC Resin | Iphinda isetyenziswe "Regrind" iPVC |
| Ukukhuselwa kwe-UV | Iinketho ze-UV-Resistant ziyafumaneka | I-PVC eqhelekileyo ithotywa kukukhanya kwelanga |
| Isitulo Material | Ihlala ixesha elide, i-Low-Friction PTFE | I-EPDM ethambileyo okanye irabha ye-NBR |
| Ukuvelisa | Ukungqinelana, iMveliso eSebenzayo | INdibano yeManuwali engangqinelaniyo |
Yeyiphi engcono ibhedu okanye iivalvu zebhola zePVC?
Ubona ivalve yobhedu kunye nevalve yePVC ecaleni-ngecala. Umahluko wamaxabiso mkhulu, kodwa yeyiphi eyona nto ingcono kwiprojekthi yakho? Isigqibo esingalunganga sinokubiza imali eninzi.
Akukho nanye imathiriyeli engcono jikelele; ukhetho olungcono luxhomekeke ngokupheleleyo kwisicelo. I-PVC iyagqwesa kwindawo ezonakalisayo kwaye iyabiza. Ubhedu luphezulu kumaqondo obushushu aphezulu, uxinzelelo oluphezulu, kunye neemeko ezifuna amandla amakhulu omzimba.
Lo ngomnye wemibuzo eqhelekileyo efunyanwa liqela likaKapil Motwani. Impendulo isoloko ifumaneka ngokubuza malunga nesicelo.IiPVC zeamandla amakhulu kukungangeni kwayo kwemichiza. Ayikhuselekanga ngokupheleleyo kumhlwa. Kwiinkqubo ezibandakanya amanzi omthombo, isichumisi, amanzi anetyuwa, okanye iiasidi ezithambileyo, i-PVC iya kukhupha kakhulu ubhedu. Ubhedu lunokubandezeleka kwinto ebizwa ngokuba yi-Brassdezincification, apho i-chemistry ethile yamanzi ikhupha i-zinc ngaphandle kwe-alloy, iyenza ibe yi-porous kwaye ibuthathaka. I-PVC ikwakhaphukhaphu kakhulu kwaye iyabiza kakhulu. Nangona kunjalo,ubhedunguye ophumeleleyo ocacileyo xa kufikwa kukuqina. Inokusingatha amaqondo obushushu aphezulu kunye noxinzelelo kunePVC, kwaye iyaxhathisa kakhulu kwimpembelelo yomzimba. Ukuba ufuna i-valve yomgca wamanzi ashushu, umgca womoya ophezulu, okanye kwindawo apho unokubethelwa khona, ubhedu lukhetho olukhuselekileyo. Kwizicelo ezininzi zamanzi abandayo, iPVC ibonelela ngexabiso elingcono lexesha elide.
I-PVC vs. Ubhedu: Ukuthelekiswa kweNtloko ukuya kwiNtloko
| Uphawu | Ivalve yeBhola yePVC | Ivalve yeBhola yobhedu | Ophumeleleyo ngu… |
|---|---|---|---|
| Ukunyangwa kokuMhlwa | Egqwesileyo | Ulungile (kodwa usesichengeni kwi-dezincification) | I-PVC |
| Umlinganiselo wobushushu | ~140°F (60°C) | >200°F (93°C) | Ubhedu |
| Ixabiso loxinzelelo | Ilungile (umz., 150 PSI) | Kugqwesileyo (umzekelo, 600 PSI) | Ubhedu |
| Iindleko | Phantsi | Phezulu | I-PVC |
Ngaba iivalvu zePVC zilungile?
Ukhangela umgangatho, kodwa ixabiso eliphantsi leevalvu zePVC libonakala lilunge kakhulu ukuba lingabi yinyani. Unexhala lokuba ukonga iidola ezimbalwa ngoku kuya kukhokelela kwiintsilelo ezinkulu kamva.
Ewe, iivalvu zePVC ezikumgangatho ophezulu zilunge kakhulu kwaye zibonelela ngexabiso elikhethekileyo kusetyenziso olucetywayo. Ivalve eyenziwe kakuhle yePVC eyenziwe ngezinto ezinyulu ezinamatywina alungileyo yinto eyomeleleyo kwaye inokuthenjwa kakhulu kwizicelo zolawulo lwamanzi ezingenakubalwa.
Ngaba iivalvu zebhola zePVC ziyasilela?
Ufuna ukufaka icandelo ongasoze ucinge ngalo kwakhona. Kodwa zonke iindawo zinendawo yokuphuka, kwaye ukungazi ukuba kunokukhokelela kwiintlekele ezinokuthintelwa.
Ewe, iivalve zebhola ze-PVC zinokungaphumeleli, kodwa ukungaphumeleli phantse kubangelwa kukusetyenziswa kakubi okanye ukufakwa okungafanelekanga, kungekhona ngesiphene kwivalve yekhwalithi. Ezona zizathu zixhaphakileyo zokusilela kukukhenkceza, ukuchanabeka kwiikhemikhali ezingahambelaniyo okanye amanzi ashushu, kunye nomonakalo emzimbeni.
Iindlela zokuSilela eziqhelekileyo kunye noThintelo
| Imo Yokusilela | Unobangela | Indlela Yokukuthintela |
|---|---|---|
| Umzimba Oqhekekileyo | Amanzi abandayo; ukuqinisa ngaphezulu. | Khupha imibhobho ngaphambi kokuba ngumkhenkce; qinisa ngesandla dibanisa ijiko elinye ngesitshixo. |
| Isiphatho esivuzayo | Isiqu esigugileyo okanye esikrazukileyo sama-O-ring. | Khetha ivalve esemgangathweni ene-double O-rings. |
| Ukuvuza Xa Kuvaliwe | Ibhola ekrweliweyo okanye izihlalo. | Imibhobho yokucoca phambi kokufakwa; sebenzisa kuphela izithuba ezivulekileyo/ezivaliweyo. |
| Isiphatho esaphukileyo | Umonakalo we-UV; amandla agqithisileyo kwivalve ebambekayo. | Sebenzisa i-UV-resistant valves ngaphandle; phanda unobangela wokuqina. |
Ukuqukumbela
Iivalvu zebhola zePVC ezikumgangatho ophezulu zithembeke ngokumangalisayo. Ukuxhathisa kwabo kwi-corrosion kubanika inzuzo enkulu ngaphezu kwesinyithi kwizicelo ezininzi zamanzi. Ngokukhetha imveliso esemgangathweni, uqinisekisa ixesha elide, ukusebenza okuthembekileyo.
