Udinga ivalvu elula yokuvula/yokuvala kwipayipi yamanzi ephambili, kodwa ukhetho lubonakala lunzima. Ukukhetha uhlobo olungalunganga kunokuthetha ukuba awukwazi ukubona ukuba ivuliwe okanye ivaliwe, nto leyo ekhokelela kwiimpazamo zokusebenza.

Iintlobo ezimbini eziphambili zeevalvu zesango yi-stem ephakamayo kunye ne-stem engaphakamayo.iivalvu zesiqu ezinyukayoIsibambo sinyuka sisehla nesango, sibonisa indawo yaso.isiqu esingavukiyoIsibambo sika-'s sijikeleza kuphela endaweni yaso.

Xa ndixoxa ngeeprojekthi zamanzi ezinkulu neqabane lam uBudi, umxholo weevalvu eziphambili zokwahlukanisa uhlala uvela. Abathengi bakhe eIndonesia bafuna iindlela ezithembekileyo zokuvala amanzi ukuze agcinwe ngaphandle kokuqikelela. Ukukhetha phakathi kwesiqu esinyukayo kunye nevalvu yesiqu esinganyukiyo ngumzekelo ogqibeleleyo wendlela umahluko omncinci woyilo onokuba nefuthe elikhulu ngayo kwimisebenzi yemihla ngemihla. Enye ikunika uphawu olucacileyo olubonakalayo, ngelixa enye incinci ngakumbi. Ukuqonda lo mahluko ubalulekileyo ngundoqo wokukhetha ivalvu efanelekileyo yomsebenzi.

Zithini iingxaki zokusebenzisa iivalvu zesango?

Ufake ivalvu yesango, kodwa ngoku kufuneka unciphise ukuhamba kwamanzi, ungayiyeki. Ukuzama ukusebenzisa ivalvu yesango ngale njongo kunokonakalisa ivalvu ngokukhawuleza kwaye kubangele iingxaki kumbhobho wakho.

Iivalvu zesango azikwazi ukuhamba kakuhle. Zinokungcangcazela zize zibangele ukukhukuliseka kwezihlalo kunye neediski xa zivuliwe kancinci. Zikwasebenza kancinci kwaye zinokubanjwa lula kukwakheka kwesanti.

Iivalvu zesango zenzelwe umsebenzi omnye: ukuba zivuleke ngokupheleleyo okanye zivalwe ngokupheleleyo. Zibalasele kakhulu koku. Xaivalvu yesangoivuliwe ngokupheleleyo, "isango" lingaphandle kwendlela yokuhamba, ngoko ke phantse akukhoukwehla koxinzelelo. Kodwa xa uzama ukuyisebenzisa ukulawula ukuhamba kwamanzi ngokuyishiya ivulekile kancinci, iingxaki ziyaqala. Amanzi ahamba ngesantya esiphezulu angena kwindawo encinci adala ukuxinana okukhulu. Oku kuxinana kubangela ukuba isango lingcangcazele kwaye lithethe nxamnye nesihlalo salo. Ekuhambeni kwexesha, oku kukhukuliseka kuya konakalisa ngokusisigxina imiphezulu yokutywina yesango kunye nomzimba. Xa ekugqibeleni uzama ukuyivala ngokupheleleyo, ayisayi kudala ukutywina okugqibeleleyo kwaye iya kuvuza. Ikwacotha kakhulu. Ivalvu enkulu yesango inokuthatha amashumi okanye amakhulu eenguqu zesiphatho ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvaliwe ngokupheleleyo.

Izinto Ezingalunganga Eziphambili NgeeValve Zesango

Ndingayisebenzisa ivalvu yesaddle kwiPVC?

Udinga ukucofa umgca wamanzi wePVC okhoyo ukuze ufumane uqhagamshelo oluncinci. Ivalvu yesali ibonakala ngathi sisisombululo esikhawulezayo nesilula, kodwa unexhala lokuba inokonakalisa umbhobho weplastiki.

Hayi, akufuneki usebenzise umgangathoivalvu yesihlalokwipayipi yePVC. Iivalvu zesali zisebenza ngokugqobhoza ipayipi, nto leyo eya kubangela ukuba iPVC iqhekeke ize ingaphumeleli, nto leyo ekhokelela ekuvuzeni okukhulu.

Eli linqaku elibalulekileyo lokhuseleko endisoloko ndiligxininisa kwiBudi. Iivalvu zesaddle zenzelwe iipayipi zesinyithi eziqinileyo ezifana nobhedu. Zinephini ebukhali onokuyikrufula ukuze ugqobhoze udonga lombhobho ukuze wenze ipompo yamanzi. Le ndlela yintlekele kwiPVC. IPVC inamandla, kodwa ikwayinto ebuthathaka. Oku kuthetha ukuba ukuba udala indawo ebukhali yoxinzelelo, njengomngxuma ovela kwiphini ebhobozayo, umngxuma unokuqala kwaye uhambe ngokulula eludongeni lombhobho. Uxinzelelo oluqhubekayo lwamanzi luya kusebenzisa eli nqaku libuthathaka. Isenokungavuzi ngoko nangoko, kodwa ngokuhamba kwexesha, ngotshintsho kuxinzelelo nakubushushu, loo mngxuma mncinci uya kuba ngumngxuma omkhulu kwaye umbhobho uya kugqabhuka. Indlela echanekileyo yokuchukumisa umgca wePVC kukusebenzisa "i-t-shirt yesihlalo"okanye" umkhono wokuthepha." Ezi zinto zincamathisela okanye zibopha umbhobho, uze emva koko usebenzise i-drill ukwenza umngxuma ococekileyo, ukubonelela ngonxibelelwano olukhuselekileyo nolungavuziyo ngaphandle kokubeka emngciphekweni ulwakhiwo lombhobho.

Yeyiphi ivalvu yesango esetyenziswa kakhulu nesetyenziswa kakhulu?

Kufuneka ubeke uhlobo oluqhelekileyo lwevalvu yesango lokusasazwa kwamanzi ngokubanzi. Ufuna ukubonelela leyo abathengi bakho abaya kuyicela rhoqo ukuze kube lula ukugcina izinto zakho.

Uhlobo oluqhelekileyo nolusetyenziswa kakhulu yiisiqu esingavukiyo (i-NRS), i-wedge eqinileyo,ivalvu yesango ehlala iqinileIyathandwa ngenxa yoyilo lwayo oluncinci, ukuqina, kunye nokufaneleka kwayo kwimisebenzi yamanzi engaphantsi komhlaba kunye nemibhobho eqhelekileyo.

Olu hlobo luthile lusetyenziswa kakhulu kushishino lwamanzi, kwaye yivalvu abathengi bakaBudi abaqhelene nayo kakhulu. Makhe sichaze isizathu sokuba ithandwe kangaka. "Isiqu esinganyukiyo" sithetha ukuba sincinci kakhulu, esifanelekileyo ukufakwa kwiindawo ezixineneyo okanye ezingcwatywe phantsi komhlaba, njengoko ungadingi ndawo yongezelelweyo yokuba isiqu sihambe siye phezulu nasezantsi. "I-Solid wedge" ibhekisa kwisango elilula, eliqinileyo, elinomgca omnye ngaphakathi, elithembekileyo nelingabizi kakhulu. Eyona nto ibalulekileyo "lihlala phantsi." Oku kuthetha ukuba isango lesinyithi ligqunywe ngerabha (njenge-EPDM). Xa ivalvu ivala, le wedge yerabha icinezela umzimba ongaphakathi ogudileyo wevalvu, idala isitywino esiqinileyo sebhamuza. Olu yilo lungcono kakhulu ekutywineni kunezihlalo ezindala zentsimbi ukuya kwisinyithi kwaye luthintela inkunkuma ukuba ibambeke ezantsi, iqinisekisa isitywino esingcono sexesha elide. Yile nhlanganisela yoyilo oluncinci, oluthembekileyo, nolungenako ukuvuza oluye lwenza ukuba lube ngumgangatho wehlabathi kwiindlela zamanzi.

Ziziphi ezinye iindlela ezingasetyenziswayo endaweni yevalvu yesango?

Udinga ivalvu yokuvula/yokuvala, kodwa ivalvu yesango ibonakala icotha kakhulu okanye ayifanelekanga ukusetyenziswa. Kufuneka wazi ukuba zeziphi ezinye iindlela ezikhoyo ukuze wenze ukhetho olufanelekileyo.

Iindlela ezimbini eziphambili zokutshintsha iivalvu zesango ziivalvu zebhola kunye neevalvu zebhabhathane. Iivalvu zebhola zilungile kakhulu ekuvalekeni ngokukhawuleza, okujika ngekota kwimibhobho emincinci. Iivalvu zebhabhathane zikhetho olungabizi kakhulu kwimibhobho emikhulu.

Ukukhetha phakathi kwezi valve kuxhomekeke ngokupheleleyo kumsebenzi.ivalvu yebholasisincomo sam kuyo nayiphi na ipayipi enobubanzi obuyi-intshi ezi-4. Isebenzisa ibhola yesinyithi enomngxuma kuyo. Ukujika nje okulula kwesiphatho ngama-degree angama-90 kulungelelanisa umngxuma nombhobho ukuze uphume ngokupheleleyo okanye kujikelezise ukugeleza ukuze kumiswe ngokupheleleyo. Oku kwenza ukuba isebenze ngokukhawuleza kakhulu, kwaye ungayibona indawo yayo ngokujonga nje isiphatho. Ikwangcono kakhulu ekuthobeni ukugeleza kunevalvu yesango. Kwimibhobho emikhulu kakhulu, njengesixhobo samanzi esiziisentimitha ezili-12, ivalvu yesango iba nkulu kwaye ibize kakhulu. Kulapho i-ivalvu yebhabhathaneigqibelele. Isebenzisa idiski encinci embindini wepayipi ejikeleza ama-90 degrees ukuvula okanye ukuvala. Zilula, zincinci, kwaye zifikeleleka lula kunevalvu enkulu yesango, nto leyo eyenza ukuba zibe lolona khetho luqhelekileyo kwiindawo ezinkulu zokucoca amanzi kunye nezityalo zoshishino.

I-Sango Valve vs. Ezinye iindlela

Uhlobo lweValve	Eyona ilungileyo	Iingcali	Iingxaki
Ivalvu yeSango	Ukwahlukaniswa okuvulekileyo/okuvaliweyo ngokupheleleyo	Ukuhamba okungenakuthintelwa, uphawu oluhle	Icotha, ayilunganga xa idlala
Ivalvu yeBhola	Ukuvala ngokukhawuleza, iipayipi ezincinci	Iyakhawuleza, ithembekile, ilungele ukuqhobosha	Ixabiso eliphantsi kakhulu, uxinzelelo oluphezulu
Ivalvu yebhabhathane	Iipayipi ezinkulu	Ilula, ixabiso liphantsi, iyakhawuleza	Idiski ihlala isebenza rhoqo

Isiphelo

Iivalvu zesangoziza njengeentlobo zeziqu ezikhulayo okanye ezingakhuphukiyo, zilungele ulawulo olulula lokuvula/ukucima. Kwezinye iimfuno,ibholakwayeiivalvu zebhabhathaneinika ukusebenza okukhawulezayo kunye nokusebenza okungcono kwiisayizi ezahlukeneyo zepayipi.
