Ubheke ipayipi, futhi kukhona isibambo esiphumela ngaphandle. Udinga ukulawula ukugeleza kwamanzi, kodwa ukwenza ngaphandle kokwazi ngokuqinisekile kungaholela ekuvuzeni, ukulimala, noma ukuziphatha kwesistimu okungalindelekile.

Ukusebenzisa indinganisoI-valve yebhola ye-PVC, vula isibambo ikota-turn (90 degrees). Lapho isibambo sihambisana nepayipi, i-valve ivuliwe. Lapho isibambo si-perpendicular kumbhobho, i-valve ivaliwe.

Lokhu kungase kubonakale kuyisisekelo, kodwa kuwucezu lolwazi olubaluleke kakhulu kunoma ubani osebenza ngamapayipi. Ngihlale ngitshela uzakwethu, u-Budi, ukuthi ukwenza isiqiniseko sokuthi ithimba lakhe labadayisi lingakwazi ukuchaza ngokucacile lezi zisekelo kosonkontileka abasha noma amakhasimende e-DIY kuyindlela elula yokwakha ukwethembana. Uma ikhasimende lizizwa liqiniseka ngomkhiqizo, ngisho nangendlela encane, kungenzeka lithembe umsabalalisi owalifundisa. Yisinyathelo sokuqala sobambiswano oluyimpumelelo.

I-valve ye-PVC isebenza kanjani?

Uyazi ukuphendula isibambo kuyasebenza, kodwa awazi ukuthi kungani. Lokhu kwenza kube nzima ukuchaza inani layo ngaphandle nje kokuthi uvule/uvale iswishi noma ukuxazulula inkinga uma kukhona okungahambi kahle.

I-valve yebhola ye-PVC isebenza ngokuzungezisa ibhola eliyindilinga elinembobo kulo. Uma uphendula isibambo, imbobo iqondana nepayipi ukuze igeleze (ivule) noma ijike ukuze ivimbe ipayipi (ivaliwe).

Ubuhlakani bei-valve yebholaubulula nokusebenza kwayo. Uma ngikhombisa isampula eqenjini likaBudi, ngihlale ngikhomba izingxenye ezibalulekile. Ngaphakathi kwe-valveumzimba, kukhona Iibholaenembobo, eyaziwa ngokuthi ichweba. Leli bhola lihlezi kahle phakathi kwama-seals amabili aqinile, thina kwa-Pntek esenza ngawoI-PTFEukuphila isikhathi eside. Ibhola lixhunywe ngaphandleisibambongeposi elibizwa ngokuthiisiqu. Uma uphendulela isibambo ngamadigri angu-90, isiqu sizungeza ibhola. Lesi senzo sekota yikona okwenza ama-valve ebhola asheshe futhi asebenze kalula. Idizayini elula, eqinile ehlinzeka ngokuvalwa okuphelele nokuthembekile okunezingxenye ezimbalwa kakhulu ezihambayo, yingakho kuyindinganiso yezinhlelo zokulawula amanzi emhlabeni jikelele.

Ungasho kanjani ukuthi i-valve ye-PVC ivuliwe noma ivaliwe?

Usondela kuvalvu ohlelweni lwamapayipi oluyinkimbinkimbi. Ngeke uqiniseke ukuthi ivumela amanzi adlule noma cha, futhi ukuqagela okungalungile kungase kusho ukufuthwa noma ukuvala umugqa ongalungile.

Bheka indawo yesibambo uma kuqhathaniswa nepayipi. Uma isibambo sihambisana (sigijima ngendlela efanayo nepayipi), i-valve ivuliwe. Uma i-perpendicular (ukwenza umumo “T”), ivaliwe.

Lo mthetho obonakalayo uyindinganiso yemboni ngesizathu: unengqondo futhi awushiyi indawo yokungabaza. Ukuqondiswa kwesibambo kulingisa ngokoqobo isimo sembobo ngaphakathi kwevalvu. Ngihlale ngitshela uBudi ukuthi iqembu lakhe kufanele ligcizelele lo mthetho olula—“Ukufana kusho ukudlula, i-Perpendicular isho ukuthi Ixhunyiwe.” Le nsiza yenkumbulo encane ingavimbela amaphutha abizayo kubadwebi bezindawo, ochwepheshe be-pool, kanye nezisebenzi zokunakekela izimboni ngokufanayo. Isici sokuphepha esakhelwe edizayini. Uma ubona isibambo se-valve nge-engeli engama-degree angu-45, kusho ukuthi i-valve ivuleke kancane, ngezinye izikhathi engase isetshenziselwe ukugeleza kwe-throttling, kodwa idizayini yayo eyinhloko ingeyezindawo ezivuleke ngokugcwele noma ezivalwe ngokugcwele. Ukuze uvale i-positive, qiniseka njalo ukuthi i-perpendicular ngokugcwele.

Indlela yokuxhuma i-valve kupayipi le-PVC?

Une-valve yakho nepayipi, kodwa ukuthola uphawu oluvikelekile, olungavuzi kubalulekile. Ilunga elilodwa elibi lingaphazamisa ubuqotho balo lonke uhlelo, okuholela ekuhlulekeni nasekusebenzeni kabusha okubizayo.

Ukuze uthole i-valve ye-solvent weld, sebenzisa i-PVC primer, bese usimende kokubili ekugcineni kwepayipi kanye nesokhethi ye-valve. Ziphushe ndawonye bese unikeza ikota-turn. Kumavalve anentambo, bopha izintambo ngetheyiphu ye-PTFE ngaphambi kokuqiniswa.

Ukuthola ukuxhumeka kwesokudla akuxoxiswana ngesistimu ethembekile. Lena indawo lapho izinto zekhwalithi kanye nenqubo efanele kuyizinto zonke. Ngeluleka ithimba likaBudi ukuthi lifundise amakhasimende abo lezi zindlela ezimbili:

1. I-Socket Welding (ye-Socket Valves)

Lena indlela evame kakhulu. Kwakha isibopho esihlala njalo, esihlanganisiwe.

1. Lungiselela:Yenza ukusika okuhlanzekile, okuyisikwele epayipini lakho bese ususa noma yimaphi ama-burrs.
2. Okuyinhloko:Faka isicelo sokuqala se-PVC ngaphandle kwepayipi nangaphakathi kwesokhethi ye-valve. I-Primer ihlanza indawo futhi iqala ukuthambisa i-PVC.
3. Usimende:Faka ngokushesha ungqimba lukasimende we-PVC phezu kwezindawo ezikhonjiwe.
4. Xhuma:Ngokushesha phusha ipayipi esokhethini ye-valve futhi uyinike ikota-turn ukusabalalisa usimende ngokulinganayo. Yibambe imizuzwana engu-30 ukuvimbela ipayipi ukuthi lingaphusheli ngaphandle.

2. Uxhumano Olunemicu (Okwamavavu Anemicu)

Lokhu kuvumela ukuqaqa, kodwa ukuvala uphawu kuyisihluthulelo.

1. Itheyiphu:Goqa itheyiphu ye-PTFE (i-Teflon tape) izikhathi ezi-3-4 uzungeze imicu yesilisa ngendlela yewashi.
2. Qinisa:Khipha i-valve ekuqiniseni isandla, bese usebenzisa isikrufu omunye ukujika okubili. Ungaqinisi kakhulu, njengoba ungaqhekeka i-PVC.

Ungahlola kanjani ukuthi i-valve ye-PCV iyasebenza?

Usola ukuthi i-valve iyehluleka, okubangela izinkinga ezifana nomfutho ophansi noma ukuvuza. Uzwa ngokuhlola “i-valve ye-PCV” kodwa awunasiqiniseko sokuthi lokho kusebenza kanjani epayipini lakho lamanzi.

Okokuqala, cacisa igama. Usho ivalvu ye-PVC (ipulasitiki), hhayi i-PCV yenjini yemoto. Ukuze uhlole i-valve ye-PVC, vula isibambo. Kufanele ihambe kahle ngo-90° futhi imise ukugeleza ngokuphelele lapho ivaliwe.

Lona umehluko obaluleke kakhulu engiqinisekisa ukuthi iqembu likaBudi liyawuqonda. I-PCV imele i-Positive Crankcase Ventilation futhi iyingxenye yokulawula ukungcola emotweni. I-PVC imele i-Polyvinyl Chloride, ipulasitiki amavalvu ethu enziwe ngayo. Ikhasimende elizixubayo kuvamile.

Nalu uhlu lokuhlola olulula ukuze ubone ukuthi aI-valve ye-PVCisebenza kahle:

1. Hlola isibambo:Ingabe iphenduka amadigri angu-90 agcwele? Uma iqinile kakhulu, izimvu zamanzi zingase zibe zindala. Uma ixega noma iphenduka ngokukhululekile, isiqu esingaphakathi cishe siphukile.
2. Hlola Ukuvuza:Bheka amaconsi avela emzimbeni wevalvu noma lapho isiqu singena khona esibambo. Kwa-Pntek, ukuhlanganisa kwethu okuzenzakalelayo nokuhlola ingcindezi kunciphisa lezi zingozi zisuka nje.
3. Hlola i-Shutoff:Vala i-valve ngokuphelele (isibambo se-perpendicular). Uma amanzi esageleza emugqeni, ibhola langaphakathi noma ama-seal alimele, futhi i-valve ngeke isakwazi ukunikeza ukuvala okuhle. Idinga ukushintshwa.

Isiphetho

Ukusebenzisa aI-valve ye-PVCilula: isibambo parallel kusho evulekile, perpendicular ivaliwe. Ukufakwa okufanelekile kwe-solvent-weld noma intambo nokuhlola ukusebenza
