Usebenza kumgca wamanzi kwaye ufuna ivalve. Kodwa ukusebenzisa uhlobo olungalunganga kunokukhokelela kumhlwa, ukuvuza, okanye ukuchitha imali eninzi kwivalvu engaphezulu.
Iivalvu zebhola zePVC zisetyenziswa ikakhulu kulawulo lokuvula/lokuvala kwimibhobho yamanzi abandayo kunye neenkqubo zokuphatha ulwelo. Ezona zinto zixhaphakileyo zisetyenziselwa ukunkcenkceshela, amachibi kunye neendawo zokuhlambela, i-aquaculture, kunye nemigca yamanzi enjongo jikelele apho ukuxhathisa umhlwa kubalulekile.
Ndihlala ndibuzwa lo mbuzo ngamahlakani afana noBudi, umphathi wokuthenga e-Indonesia. Xa eqeqesha abathengisi abatsha, enye yezinto zokuqala ekufuneka bazifunde ayikokucengceleza nje iimpawu zemveliso, kodwa ukuqonda umsebenzi womthengi. Umthengi akafuni nje ivalve; bafuna ukulawula amanzi ngokukhuselekileyo nangokuthembekileyo. Ivalve yebhola yePVC ayiyonto nje yeplastiki; ngumgcini-sango. Ukuqonda apho kwaye kutheni isetyenziswa kuvumela iqela lakhe ukuba linike isisombululo sokwenyani, hayi nje ukuthengisa inxalenye. Konke malunga nokuhambelana nesixhobo esifanelekileyo kumsebenzi ofanelekileyo, kwaye ezi zivalo zineseti ethile yemisebenzi abayenzayo ngokugqibeleleyo.
Zisetyenziselwa ntoni iivalvu zebhola zePVC?
Ubona iivalvu zePVC ezisetyenziswa kuyo yonke into ukusuka kwiifama ukuya ngasemva. Kodwa yintoni ebenza ukhetho olufanelekileyo kule misebenzi kunye nokukhetha okungalunganga kwabanye? Ibalulekile.
Iivalvu zebhola zePVC zisetyenziselwa ngokukodwa ukulawula ukuhamba kwiinkqubo zamanzi abandayo. Izicelo eziphambili ziquka ukunkcenkceshela, imibhobho yamanzi kwidama lokuqubha, i-aquaculture, i-aquaponics, kunye nemibhobho ekhanyayo yorhwebo okanye yendawo yokuhlala apho irusi kunye nokuhlwa kweekhemikhali kuyinkxalabo.
Makhe sijonge apho ezi zivalo zikhanya khona. Kwiukunkcenkceshela, basebenza njengokuvalwa komgca oyintloko okanye ukulawula iindawo ezahlukeneyo zokunkcenkceshela. Bahlala ekungcoleni kwaye bahlala bevezwa ngamanzi kunye nesichumisi, indawo eya kutshabalalisa ezininzi iivalve zetsimbi, kodwa i-PVC ayithinteki ngokupheleleyo. Kwiamachibi kunye ne-spas, amanzi aphathwa ngeklorini okanye ityuwa. I-PVC ngumgangatho weshishini weempompo zemibhobho kunye nezihlungi kuba ikhuselekile ngokupheleleyo kule nkunkuma yekhemikhali. Okufanayo kuya kwi-aquaculture, apho balawula ukuhamba kwamanzi kwiintlanzi kunye nokulima kwe-shrimp. Kwimibhobho eqhelekileyo, iyona nto ibalaseleyo, indleko ephantsi yokhetho kuyo nayiphi na umgca wamanzi abandayo, njengenkqubo yokutshiza okanye njengento yokuvalwa okukhulu, apho ufuna indlela ethembekileyo yokumisa ukuhamba kokugcinwa okanye ukuxakeka.
Izicelo eziqhelekileyo zePVC Ball Valves
| Isicelo | Kutheni iPVC ilolona khetho lubalaseleyo |
|---|---|
| Unkcenkceshelo & nezoLimo | Amajoni akhusela umhlwa emhlabeni, amanzi kunye nezichumisi. |
| Amachibi, ii-Spa & namachibi | Ayinakonakaliswa yiklorine, amanzi anetyuwa, okanye olunye unyango. |
| Ulimo lwasemanzini kunye neeAquariums | Ukuphatha ngokukhuselekileyo ukuhamba kwamanzi rhoqo ngaphandle kokuthotywa okanye ukuvuza. |
| Imibhobho yamanzi abandayo ngokubanzi | Ibonelela ngendawo ethembekileyo, engangenwa ngumhlwa, kunye nendawo yokuvala efikelelekayo. |
Yintoni injongo yesivalo sePVC?
Unamanzi aqukuqela ngombhobho, kodwa akunandlela yokuwanqanda. Oku kungabikho kolawulo kwenza ukulungiswa okanye ukugcinwa kungenakwenzeka kwaye kube yingozi. Ivalve elula iyayilungisa le nto.
Injongo ephambili ye-valve ye-PVC kukubonelela ngendawo yokulawula ethembekileyo kunye neyomeleleyo kwinkqubo yolwelo. Ikuvumela ukuba uqale, uyeke, okanye ngamanye amaxesha ulawule ukuhamba, kunye nenzuzo ephambili yokumelana ngokupheleleyo nokubola.
Injongo esisiseko yayo nayiphi na ivalve lulawulo, kwaye iivalvu zePVC zibonelela ngohlobo oluthile lolawulo. Eyona njongo yabo iphambiliukubekwa wedwa. Yiba nomfanekiso wentloko yokutshiza igqabhuka eyadini yakho. Ngaphandle kwevalve, kuya kufuneka uvale amanzi kwindlu yonke ukuze ulungise. Ivalve yebhola yePVC ebekwe kulo mgca ikuvumela ukuba uhlukanise elo candelo, wenze ukulungiswa, kwaye uyivule kwakhona. Oku kubalulekile kulo naluphi na uhlobo lolondolozo. Enye injongo nantsiukuphambukisa. Ukusebenzisa ivalve yebhola eneendlela ezi-3, unokuhamba ngokuthe ngqo ukusuka kumthombo omnye ukuya kwiindawo ezimbini ezahlukeneyo, njengokutshintsha phakathi kweendawo ezimbini ezahlukeneyo zokunkcenkceshela. Okokugqibela, imathiriyeli yePVC ngokwayo isebenzela injongo:ubomi obude. Yenza umsebenzi wokulawula amanzi ngaphandle kokugqwala okanye ukugqwala, iqinisekisa ukuba iya kusebenza xa uyifuna, unyaka nonyaka. Leyo yinjongo yayo yokwenyani: ulawulo oluthembekileyo oluhlala luhleli.
Yintoni eyona njongo yevalve yebhola?
Kufuneka uvale umgca wamanzi ngokukhawuleza kwaye uqiniseke ngokupheleleyo. Iivalvu ezicothayo ezifuna ujiko oluninzi zinokukushiya uzibuza ukuba ingaba ivalve ngenene, ivalwe ngokupheleleyo.
Eyona njongo iphambili yevalve yebhola kukubonelela ngokukhawuleza nangokuthembekileyo kulawulo lokuvala/ukuvala. Uyilo lwalo olulula lwekota luvumela ukusebenza ngokukhawuleza, kwaye indawo yokubamba inika umqondiso ocacileyo ocacileyo wokuba ivuliwe okanye ivaliwe.
Ubukrelekrele bevalve yebhola kukulula kwayo. Ngaphakathi kwevalve kukho ibhola egqojozwe umngxuma ngqo kuyo. Xa isibambo sihambelana nombhobho, umgodi uhambelana nokuhamba, kwaye i-valve ivuleke ngokupheleleyo. Xa uguqula isibambo se-90 degrees, iba yi-perpendicular kumbhobho. Oku kujikelezisa ibhola ukuze inxalenye eqinileyo ivalele ukuhamba, ukuyivala ngoko nangoko. Olu luyilo lunikezela ngeenzuzo ezimbini eziphambili ezichaza injongo yalo. Okokuqala kukubaisantya. Ungahamba ukusuka ekuvuleni ngokupheleleyo ukuya kuvaliwe ngokupheleleyo kwiqhezu lomzuzwana. Oku kubalulekile xa kucinywa ngokukhawuleza. Okwesibini nguukucaca. Uyakwazi ukuxelela imeko yevalve ngokujonga nje isiphatho. Akukho ukuqikelela. Ndihlala ndixelela uBudi ukuba athengise oku njengento yokhuseleko. Ngevalve yebhola, uyazi ngokuqinisekileyo ukuba amanzi avuliwe okanye avaliwe.
Uthini umahluko phakathi kwevalve yebhola yobhedu kunye nevalve yebhola yePVC?
Ufuna ivalve yebhola, kodwa ubona enye yobhedu kunye nePVC. Zibukeka zahluke kakhulu kwaye zinamaxabiso ahluke kakhulu. Ukukhetha engalunganga kunokukhokelela ekubeni usilele.
Umahluko ophambili ulele kwiipropati zabo eziphathekayo kunye neemeko ezifanelekileyo zokusetyenziswa. I-PVC ilula, i-corrosion-proof, kwaye ilungele amanzi abandayo. Ubhedu lunamandla kakhulu, lubamba ukushisa okuphezulu kunye noxinzelelo, kodwa lunokonakala kwiimeko ezithile.
Xa ndichaza oku kuBudi kwiqela lakhe, ndiyayiqhekeza kwiindawo ezine eziphambili. Okokuqala kukubaukumelana nomhlwa. Apha, iPVC yintshatsheli engenakuphikiswa. Luhlobo lweplastiki, ngoko ayinako ukurusa. I-Brass yi-alloy enokuthi ibe buthathaka yikhemistri yamanzi athile ngokuhamba kwexesha. Okwesibini nguubushushu kunye noxinzelelo. Apha, ubhedu luphumelela ngokulula. Iyakwazi ukujongana namanzi ashushu kunye noxinzelelo oluphezulu kakhulu, ngelixa i-PVC eqhelekileyo isetyenziselwa amanzi abandayo kuphela (ngaphantsi kwe-60 ° C / 140 ° F) kunye noxinzelelo oluphantsi. Okwesithathu kukubaamandla. Ubhedu yintsimbi kwaye yomelele ngakumbi xa kuthelekiswa nefuthe lomzimba. Awunakufuna ukusebenzisa iPVC kwimigca yegesi yendalo ngenxa yesi sizathu. Okwesine nguiindleko. I-PVC ilula kakhulu kwaye iyabiza kakhulu, iyenza ibe lolona khetho loqoqosho kwiiprojekthi ezinkulu. Ukhetho olufanelekileyo luxhomekeke ngokupheleleyo kumsebenzi.
I-PVC vs. Ubhedu: Iiyantlukwano eziphambili
| Uphawu | Ivalve yeBhola yePVC | Ivalve yebhola yobhedu |
|---|---|---|
| Engcono Kwi | Amanzi abandayo, ulwelo oludlekayo | Amanzi ashushu, uxinzelelo oluphezulu, igesi |
| Ubushushu | Phantsi (< 60°C / 140°F) | Phezulu (> 93°C / 200°F) |
| Ukonakala | Ukuchasa okugqwesileyo | Kulungile, kodwa inokugqwala |
| Iindleko | Phantsi | Phezulu |
Ukuqukumbela
Iivalvu zebhola zePVCzisetyenziselwa ukulawula / ukucima okuthembekileyo kwiinkqubo zamanzi abandayo. Ziyagqwesa kwizicelo ezinje ngonkcenkceshelo kunye namadama apho ubume bazo bobungqina bokumhlwa bubenza babe lolona khetho lubalaseleyo.
