Ufake ngokucophelela ivalvu entsha ye-PVC enezintambo, kodwa iyancipha kancane kancane ezintanjeni. Ukuyiqinisa kuzwakala kuyingozi, njengoba wazi ukuthi ukujika okukodwa kakhulu kungaphula ukulingana.

Ukuze ufake ngempumelelo ivalvu yebhola ye-PVC enezintambo, songa izintambo zesilisa ngezingqimba ezingu-3-4 zeteyipu ye-Teflon. Njalo songa ngendlela yokuqinisa. Bese uyibopha ngesandla, bese usebenzisa isikrufu ukujika okokugcina okukodwa noma okubili.

Intambo evuzayo ingenye yezinkinga ezivame kakhulu nezikhungathekisayo zokufaka. Cishe njalo ibangelwa yiphutha elincane, elingagwenywa ekulungiseleleni noma ekuqiniseni. Ngivame ukuxoxa ngalokhu nomlingani wami e-Indonesia, uBudi, ngoba kuyikhanda elihlala likhona amakhasimende akhe abhekene nalo. Ukuxhumana okuphephile, okungenawo umthambo ovuzayo empeleni kulula ukukufeza. Udinga nje ukulandela izinyathelo ezimbalwa ezilula, kodwa ezibucayi kakhulu. Ake sixoxe ngemibuzo ebalulekile ukuze sikwenze kahle njalo.

Ungazifaka kanjani izinto zokufaka amapayipi e-PVC anezintambo?

Usebenzise i-thread sealant paste esebenza kahle kakhulu ensimbini, kodwa i-PVC fitting yakho isavuza. Okubi nakakhulu, ukhathazekile ukuthi amakhemikhali akwi-paste angase alimaze ipulasitiki ngokuhamba kwesikhathi.

Nge-PVC enezintambo, sebenzisa njalo iteyipu ye-Teflon esikhundleni se-dope noma i-paste yepayipi. Songa izintambo zesilisa izikhathi ezingu-3-4 ngendlela efanayo uzoqinisa i-fitting, uqinisekise ukuthi iteyipu ilala iqonde futhi ibushelelezi ukuze kudalwe uphawu oluphelele.

Lo mehluko phakathi kwetheyiphu ne-paste ubalulekile ekufakweni kwepulasitiki.amapayipi epayipiaqukethe amakhemikhali asekelwe ku-petroleum angahlasela i-PVC ngamakhemikhali, okwenza iqhekeke futhi ikwazi ukuqhekeka ngaphansi kwengcindezi yokusebenza evamile.Itheyiphu ye-TeflonNgakolunye uhlangothi, ayisebenzi nhlobo. Isebenza njengesivali kanye nesithambisi, igcwalisa izikhala ezincane ezintanjeni ngaphandle kokudala ingcindezi yangaphandle eyingozi engenziwa yi-paste. Lokhu kuvimbela ukucindezeleka ekulinganeni kwabesifazane.

Ukukhetha Isivali Sezintambo ze-PVC

Uma usonga imicu, hlala ubheka ngakwesokunene njengoba ubheka ekugcineni kokufakwa. Lokhu kuqinisekisa ukuthi njengoba uqinisa ivalvu, itheyiphu iyashelela kunokuba ihlanganiswe futhi iqaqeke.

Ungayifaka kanjani i-ball valve epayipini le-PVC?

Unevalvu yebhola enezintambo kodwa ipayipi lakho libushelelezi. Udinga ukulixhuma, kodwa uyazi ukuthi awukwazi ukunamathisela izintambo noma ukufaka intambo epayipini elibushelelezi. Yikuphi ukulingana okufanele?

Ukuze uxhume ivalvu yebhola enezintambo epayipini le-PVC elibushelelezi, kufanele uqale ngokunamathisela i-adapter yezintambo yesilisa ye-PVC epayipini. Ngemva kokuba usimende usupholile ngokuphelele, ungafaka ivalvu enezintambo ku-adaptha.

Awusoze wakha imicu epayipini le-PVC elijwayelekile nelibushelelezi; udonga luncane kakhulu futhi luzohluleka ngokushesha. Ukuxhumana kumele kwenziwe nge-adaptha efanele. Kulo msebenzi, udinga i-I-adaptha Yabesilisa ye-PVC(ngokuvamile ibizwa ngokuthi i-adaptha ye-MPT noma ye-MIPT). Olunye uhlangothi lunesokhethi elibushelelezi, kanti olunye lunezintambo zesilisa ezibunjiwe. Usebenzisa inqubo ejwayelekile ye-PVC primer kanye nenqubo yesimende ukushisela ngamakhemikhali ukuphela kwesokhethi epayipini lakho, udale ucezu olulodwa, oluhlanganisiwe. Isihluthulelo lapha ukubekezela. Kumelwe uvumele lokhoukwelashwa kokushintshwa kwe-solventngokuphelele ngaphambi kokufaka noma iyiphi i-torque ezintanjeni. Ukusebenzisa amandla kusenesikhathi kungaphula isibopho esisha samakhemikhali, kudale ukuvuza endaweni ehlanganisiwe. Ngihlala ngiluleka amakhasimende kaBudi ukuthi alinde okungenani amahora angama-24 ukuze aphephe.

Ungayifaka kanjani ivalvu enezintambo?

Uqinise ivalvu yakho entsha enezintambo yaze yaba lukhuni, wezwa ukuqhekeka okucasulayo. Manje ivalvu yonakele, futhi kufanele uyinqume bese uqala phansi.

Indlela efanele yokuqinisa “iqinisa isandla kanye nokujika okukodwa kuya kokubili.” Mane nje ubophe ivalvu ngesandla kuze kube yilapho iqine, bese usebenzisa isipanela ukuze uyinike ukujika okukodwa noma okubili kokugcina. Yima lapho.

Ukuqinisa kakhulu kuyimbangela yokuqala yokwehluleka kwezingxenye zepulasitiki ezinezintambo. Ngokungafani nensimbi, enganwebeka futhi iguquguquke, i-PVC iqinile. Uma ucindezela ivalvu ye-PVC enezintambo, ubeka amandla amakhulu ngaphandle ezindongeni zezingxenye zesifazane, uzama ukuyihlukanisa.ukuqinisa isandla kanye nokujika okukodwa kuya kokubili"Umthetho uyindinganiso yegolide ngesizathu esithile. Ukuqinisa isandla kukodwa kwenza imicu ibambeke kahle. Ukujika okukodwa noma okubili kokugcina nge-wrench kwanele ukucindezela izendlalelo ze-teflon tape, okudala isivalo esiphelele, esingangeni manzi ngaphandle kokubeka ukucindezeleka okuyingozi epulasitikini. Ngihlala ngitshela ozakwethu ukuthi "ukuqina" akungcono nge-PVC. Ukulingana okuqinile, okuqinile kudala isivalo esihlala njalo, esingavuzi esizohlala iminyaka eminingi.

Ungaxhuma kanjani i-valve yokuvala ku-PVC?

Udinga ukwengeza ukuvala emgqeni we-PVC okhona. Awuqiniseki ukuthi kufanele usebenzise ivalvu enezintambo noma ivalvu ehlanganisiwe ejwayelekile kulolu hlelo lokusebenza oluthile.

Ukuze wengeze ukuvala emgqeni we-PVC okhona, i-valve yebhola yomanyano wangempela iyindlela engcono kakhulu. Ivumela ukulungiswa kwesikhathi esizayo. Sebenzisa inguqulo ye-solvent-weld (isokhethi) yezinhlelo ze-PVC ezihlanzekile, noma inguqulo enentambo uma ixhuma eduze kwezingxenye zensimbi.

Uma udinga ukusika umugqa ukuze wengeze ukuvala, ukucabanga ngekusasa kubalulekile. I-valve yebhola ye-union yangempela iyisinqumo esingcono kakhulu lapha. Ungasika ipayipi, unamathelise iziphetho ezimbili ze-union, bese ufaka umzimba we-valve phakathi kwazo. Lokhu kungcono kakhulu kune-valve ejwayelekile ngoba ungamane ukhulule ama-union nuts ukuze ususe wonke umzimba we-valve ukuze uhlanzwe noma ushintshwe ngaphandle kokuphinde usike ipayipi. Uma uhlelo lwakho luyi-PVC engu-100%, i-valve ye-union yangempela ye-solvent-weld (isokhethi) iphelele. Uma ufaka ukuvala eduze kwepompo noma isihlungi ngezintambo zensimbi, khona-ke i-threadedi-valve yomanyano yangempelayindlela okufanele uhambe ngayo. Ungaqala ngokunamathisela i-adaptha enezintambo epayipini le-PVC, bese ufaka ivalvu. Lokhu kuguquguquka yingakho thina kwa-Pntek sigcizelela kakhulu ukwakheka kwe-union yangempela.

Isiphetho

Ukufaka kahle intamboI-valve yebhola ye-PVC, sebenzisa iteyipu yeTeflon, hhayi ukunamathisela. Qinisa ngesandla kuqala, bese ufaka ukujika okukodwa noma okubili nge-wrench ukuze uvale kahle.
