Usebenza kumgca wamanzi kwaye udinga ivalvu. Kodwa ukusebenzisa uhlobo olungalunganga kunokubangela ukugqwala, ukuvuza, okanye ukuchitha imali eninzi kwivalvu ebiza kakhulu.
Iivalvu zebhola zePVC zisetyenziswa kakhulu ukulawula ukuvulwa/ukuvalwa kwamanzi abandayo kunye neenkqubo zokuphatha ulwelo. Eyona ndlela zisetyenziswa ngayo kakhulu kukunkcenkceshela, amachibi kunye neespa, ukulima amachibi, kunye nemijelo yamanzi ngokubanzi apho ukumelana nokugqwala kubalulekile khona.
Ndihlala ndibuzwa lo mbuzo ngamaqabane anjengoBudi, umphathi wokuthenga eIndonesia. Xa eqeqesha abathengisi abatsha, enye yezinto zokuqala ekufuneka bazifunde ayikokukhumbula nje iimpawu zemveliso, kodwa kukuqonda umsebenzi womthengi. Umthengi akafuni nje ivalvu; ufuna ukulawula amanzi ngokukhuselekileyo nangokuthembekileyo. Ivalvu yebhola yePVC ayisiyonto nje yeplastiki; ngumlindi wesango. Ukuqonda ukuba isetyenziswa phi kwaye kutheni isetyenziswa kuvumela iqela lakhe ukuba libonelele ngesisombululo sokwenyani, kungekuphela nje ngokuthengisa inxalenye. Konke malunga nokufanisa isixhobo esifanelekileyo nomsebenzi ofanelekileyo, kwaye ezi valve zinemisebenzi ethile abayenzayo ngokugqibeleleyo.
Zisetyenziselwa ntoni iivalvu zebhola zePVC?
Uyabona iivalvu zePVC zisetyenziswa kuyo yonke into ukusuka kwiifama ukuya kwiigadi zangasemva. Kodwa yintoni eyenza zibe lukhetho olufanelekileyo kule misebenzi kunye nokhetho olungalunganga kwabanye? Kubalulekile.
Iivalvu zebhola zePVC zisetyenziselwa ngokukodwa ukulawula ukuhamba kwamanzi abandayo. Izicelo eziphambili ziquka ukunkcenkceshela, imibhobho yamanzi echibini lokudada, ukulima amachibi, i-aquaponics, kunye nemibhobho yamanzi ekhaphukhaphu okanye emakhaya apho umhlwa kunye nokugqwala kweekhemikhali kuxhalabisa khona.
Makhe sijonge apho ezi valve zikhanya khona.ukunkcenkceshela, zisebenza njengeendawo zokuvala umgca oyintloko okanye ukulawula iindawo ezahlukeneyo zokunkcenkceshela. Zihlala eluthulini kwaye zihlala zichatshazelwe ngamanzi kunye nesichumiso, indawo enokutshabalalisa uninzi lweevalvu zesinyithi, kodwa i-PVC ayichaphazeleki kwaphela.amadama okubhukuda kunye neespa, amanzi anyangwa nge-chlorine okanye ityuwa. I-PVC yindlela eqhelekileyo yoshishino lweempompo zemibhobho kunye nezihluzi kuba ayichaphazeleki ngokupheleleyo yile khemikhali yokubola. Kunjalo nakwizilwanyana zasemanzini, apho zilawula ukuhamba kwamanzi ekufuyeni iintlanzi kunye nee-shrimp. Kwimibhobho eqhelekileyo, ziyindlela entle kakhulu, engabizi kakhulu kuyo nayiphi na intambo yamanzi abandayo, njengenkqubo yokutshiza okanye njengokuvalwa okuphambili, apho ufuna indlela ethembekileyo yokumisa ukuhamba kwamanzi ngexesha lokugcinwa okanye kwiimeko ezingxamisekileyo.
Izicelo eziqhelekileyo zeevalvu zebhola zePVC
| Isicelo | Kutheni i-PVC ilona khetho lubalaseleyo |
|---|---|
| Ukunkcenkceshela kunye nezoLimo | Ayikhuselekanga kumhlwa obangelwa ngumhlaba, amanzi kunye nezichumisi. |
| Amadama okubhukuda, iiSpa kunye namadama okubhukuda | Ayinakonakala yi-chlorine, amanzi anetyuwa, okanye ezinye iindlela zonyango. |
| Ukulima iintlanzi zasemanzini kunye nee-aquariums | Iphatha ngokukhuselekileyo ukuhamba kwamanzi rhoqo ngaphandle kokuwohloka okanye ukuvuza kwamanzi. |
| Iiplamba zamanzi abandayo ngokubanzi | Ibonelela ngendawo ethembekileyo, enganyangekiyo, nefikelelekayo yokuvala. |
Yintoni injongo yevalvu yePVC?
Amanzi akho ahamba ngepayipi, kodwa awunandlela yokuwamisa. Oku kungakwazi ukulawula kwenza ukulungiswa okanye ukugcinwa kwawo kube nzima kwaye kube yingozi. Ivalvu elula iyakulungisa oku.
Eyona njongo iphambili yevalvu yePVC kukubonelela ngendawo yokulawula ethembekileyo nehlala ixesha elide kwinkqubo yolwelo. Ikuvumela ukuba uqalise, uyeke, okanye ngamanye amaxesha ulawule ukuhamba kwamanzi, ngenzuzo ephambili yokuba ungamelani ngokupheleleyo nokugqwala.
Injongo eyintloko yayo nayiphi na ivalvu kukulawula, kwaye iivalvu zePVC zibonelela ngohlobo oluthile lolawulo. Injongo yazo ephambili kukulawula.ukubekwa wedwa. Khawucinge ngentloko ye-sprinkler ephukileyo ebaleni lakho. Ngaphandle kwevalvu, kuya kufuneka uvale amanzi endlwini yonke ukuze uyilungise. Ivalvu yebhola yePVC ebekwe kuloo mgca ikuvumela ukuba wahlukanise loo nxalenye, uyilungise, kwaye uyivule kwakhona. Oku kubalulekile kulo naluphi na uhlobo lolondolozo. Enye injongo yileukuphambukisaUsebenzisa ivalvu yebhola eneendlela ezintathu, ungalawula ukuhamba kwamanzi ukusuka kumthombo omnye ukuya kwiindawo ezimbini ezahlukeneyo, njengokutshintsha phakathi kweendawo ezimbini ezahlukeneyo zokunkcenkceshela. Okokugqibela, izinto zePVC zona zisebenza injongo:ubude bobomi. Yenza umsebenzi wokulawula amanzi ngaphandle kokugqwala okanye ukubola, iqinisekisa ukuba aza kusebenza xa uwadinga, unyaka nonyaka. Yiyo loo nto injongo yayo yokwenyani: ulawulo oluthembekileyo oluhlala ixesha elide.
Yintoni injongo ephambili yevalvu yebhola?
Kufuneka uvale umbhobho wamanzi ngokukhawuleza nangokuqiniseka ngokupheleleyo. Iivalvu ezicothayo ezifuna ukujika izihlandlo ezininzi zinokukushiya uzibuza ukuba ingaba ivalvu ivaliwe ngokupheleleyo ngokwenene na.
Eyona njongo iphambili yevalvu yebhola kukubonelela ngolawulo olukhawulezayo noluthembekileyo lokuvala nokuvula. Uyilo lwayo olulula lokujika ikota luvumela ukusebenza kwangoko, kwaye indawo yesiphatho inika uphawu olucacileyo olubonakalayo lokuba ivuliwe okanye ivaliwe.
Ingqondo yevalvu yebhola kukuba ilula. Ngaphakathi kwevalvu kukho ibhola enomngxuma ogqojozwe ngqo kuyo. Xa isiphatho sihambelana nombhobho, umngxuma uhambelana nokuhamba kwamanzi, kwaye ivalvu ivuleke ngokupheleleyo. Xa ujika isiphatho ngama-90 degrees, siba sithe nkqo kumbhobho. Oku kujikeleza ibhola ukuze inxalenye eqinileyo ivale ukuhamba kwamanzi, iwuvale ngoko nangoko. Olu yilo lubonelela ngeenzuzo ezimbini ezibalulekileyo ezichaza injongo yayo. Eyokuqala yileisantyaUngatshintsha ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo ngesiqingatha somzuzwana. Oku kubalulekile xa kuvalwa ngexesha likaxakeka. Okwesibini nguukucaca. Ungayibona imeko yevalvu ngokujonga nje isiphatho. Akukho kuqikelela. Ndisoloko ndixelela uBudi ukuba ayithengise le nto njengophawu lokhuseleko. Ngevalvu yebhola, uyazi ngokuqinisekileyo ukuba amanzi avuliwe okanye avaliwe.
Yintoni umahluko phakathi kwevalvu yebhola yobhedu kunye nevalvu yebhola yePVC?
Udinga ivalvu yebhola, kodwa ubona eyethusi kunye neyePVC. Zibukeka zahlukile kakhulu kwaye zinamaxabiso ahlukeneyo kakhulu. Ukukhetha engalunganga kunokukhokelela ekuweni.
Umahluko ophambili ukwiimpawu zezinto ezisetyenziswayo kunye neendawo ezifanelekileyo zokusetyenziswa. I-PVC ilula, ayidli mhlwa, kwaye ilungele amanzi abandayo. I-brass inamandla kakhulu, iphatha ubushushu obuphezulu kunye noxinzelelo, kodwa inokubola phantsi kweemeko ezithile.
Xa ndichazela uBudi oku ngenxa yeqela lakhe, ndiyakwahlukanisa kube ziinkalo ezine eziphambili. Eyokuqala yile:ukumelana nokugqwalaApha, i-PVC yeyona ntshatsheli ingenakuphikiswa. Luhlobo lweplastiki, ngoko ke ayinakugqwala. I-Brass yingxubevange enokuthi ithambe ngenxa yekhemikhali ethile yamanzi ngokuhamba kwexesha. Okwesibini yiubushushu kunye noxinzeleloApha, ithusi liphumelela ngokulula. Liyakwazi ukumelana namanzi ashushu kunye noxinzelelo oluphezulu kakhulu, ngelixa i-PVC eqhelekileyo isetyenziswa kuphela ngamanzi abandayo (angaphantsi kwama-60°C / 140°F) kunye noxinzelelo oluphantsi. Okwesithathu yi-amandlaI-Brass yintsimbi kwaye ihlala ixesha elide xa itshayiswa. Ubungayi kufuna ukusebenzisa i-PVC kwimigca yegesi yendalo ngenxa yesi sizathu. Okwesine yiixabisoI-PVC ilula kakhulu kwaye ingabizi kakhulu, nto leyo eyenza ukuba ibe lukhetho olungabizi kakhulu kwiiprojekthi ezinkulu. Ukhetho olufanelekileyo luxhomekeke ngokupheleleyo kumsebenzi.
I-PVC vs. Brass: Umahluko oPhambili
| Uphawu | Ivalvu yeBhola yePVC | Ivalvu yeBhola yeBrass |
|---|---|---|
| Eyona ilungileyo | Amanzi abandayo, ulwelo oluqhekezayo | Amanzi ashushu, uxinzelelo oluphezulu, igesi |
| Ubushushu | Phantsi (< 60°C / 140°F) | Phezulu (> 93°C / 200°F) |
| Ukugqwala | Ukumelana Okugqwesileyo | Kulungile, kodwa kunokubola |
| Ixabiso | Iphantsi | Phezulu |
Isiphelo
Iivalvu zebhola zePVCZisetyenziswa ukulawula ngokuthembekileyo ukuvala/ukuvula amanzi kwiinkqubo zamanzi abandayo. Zibalasele kwizicelo ezifana nokunkcenkceshela kunye namachibi apho ukungagqwali kwazo kuzenza zibe lolona khetho lubalaseleyo.
