Iklayenti lakho licela isiqinisekiso sokuphila konke ohlelweni lwabo olusha lokunisela. Udinga ukwazi ukuthi ama-valve ebhola le-PVC azohlala isikhathi esingakanani ukuze uphathe okulindelwe ngokunembile.

Ivalvu yebhola ye-PVC esezingeni eliphezulu ingahlala iminyaka eminingi, ngisho neminyaka engama-20 noma ngaphezulu, ngaphansi kwezimo ezifanele. Isikhathi sokuphila kwangempela sincike kakhulu ekuchayweni yi-UV, ukuthintana kwamakhemikhali, ukucindezela kwamanzi, nokuthi isetshenziswa kangaki.

Lona umbuzo engiwuxoxa njalo nabalingani abanjengoBudi wase-Indonesia. Udinga ukunikeza amakhasimende akhe ulwazi oluthembekile, kusukela kosonkontileka abakhulu kuya kubathengisi abancane. Impendulo akuyona inombolo eyodwa. Isikhathi sokuphila sevalvu yebhola le-PVC sincike ezintweni eziningana ezibalulekile. Ukuqonda lezi zici kubalulekile kokubili ekukhetheni ivalvu efanele kanye nokubeka amathemba angokoqobo kubasebenzisi bokugcina. Kumayelana nokuqinisekisa ukuthi umkhiqizo usebenza njengoba kuthembisiwe impilo yawo yonke yenkonzo.

Iyini isikhathi sokuphila sevalvu yebhola le-PVC?

Ukhetha ama-valve ephrojekthi ebalulekile. Ubona izimangalo zomkhiqizi zokuphila kweminyaka eyikhulu kwamapayipi e-PVC, kodwa uyazi ukuthi i-valve iyinkimbinkimbi kakhulu futhi izohluleka ngokushesha.

Isikhathi sokuphila ngokuvamile sinqunywa izingxenye zaso ezihambayo kanye nezimbobo. Nakuba umzimba we-PVC ungahlala iminyaka engaphezu kwengu-50, izimbobo (EPDM noma i-FPM) kanye nesihlalo (PTFE) kuzoguga kuqala, ngokuvamile kungakapheli iminyaka emi-5 kuya kwengu-20 kuye ngokuthi kusetshenziswe ini.

Umzimba we-PVC wevalvu eyenziwe kahle uqinile kakhulu. Ngaphansi kwezimo ezijwayelekile, ugqitshwe noma ungaphakathi kude nokukhanya kwelanga, ungahlala amashumi eminyaka amaningi, njengepayipi le-PVC. Kodwa-ke, ivalvu akuyona nje ingxenye yepulasitiki; iyithuluzi lomshini. Umbuzo wangempela umayelana nobude besikhathi sokuphila kwezingxenye ezihambayo nezivalayo.

Izici Eziyinhloko Ezinciphisa Isikhathi Sokuphila

Nazi izinto eziyinhloko ezinquma ukuthi izivalo nezihlalo zizohlala isikhathi esingakanani. Yizona zindawo ezibuthakathaka ngempela kunoma yiluphi uhlelo lwe-valve.

Isici	Umthelela Ebudeni Bokuphila	Indlela Yokukhulisa Impilo
Ukuvezwa kwe-UV	Kwenza i-PVC iqine, yenze buthaka izivalo.	Faka ngaphansi komhlaba, ebhokisini le-valve, noma upende ngopende osuselwe ku-latex.
Amakhemikhali	Amakhemikhali anolaka angcolisa izinto zokuvala (EPDM, FPM).	Khetha izinto zokuvala ezifanele zamakhemikhali (isib., i-FPM yamafutha).
Ukuguquguquka Kwengcindezi	I-hammer yamanzi noma ama-spikes acindezela njalo acindezela umzimba we-valve kanye nezivalo.	Faka izibambisi zesando samanzi bese usebenza ngaphansi kwesilinganiso sokucindezela esiphezulu.
Izinga lokushisa	Ukushisa okuphezulu kwenza i-PVC ithambise futhi kusheshise ukuguga kwe-seal.	Sebenzisa ivalvu ye-CPVC emanzini ashisayo futhi uhlale ngaphakathi kwemingcele yokushisa.
Imvamisa Yomjikelezo	Ukuvulwa/ukuvala njalo kuqeda isihlalo sebhola kanye nezivalo zesiqu.	Uma usebenzisa umjikelezo ophezulu, khetha ivalvu eyenzelwe ukuzenzakalela.

Ivalvu esetshenziswa entanjeni yamanzi yangaphakathi ehlanzekile, enomfutho ophansi ingahlala amashumi eminyaka. Ivalvu efanayo entanjeni yokucubungula amakhemikhali yangaphandle ingadinga ukushintshwa kwezivalo zayo njalo eminyakeni embalwa.

Kufanele uyishintshe kangaki ivalvu ye-PVC?

Unama-valve amaningi endaweni yakho. Ingabe kufanele uwashintshe ngesikhathi esinqunyiwe, noma ulinde ukuthi ahluleke? Ukwehluleka okungazelelwe kungabangela isikhukhula esikhulu.

Kufanele ushintshe ivalvu ye-PVC uma ibonisa izimpawu zokwehluleka, hhayi ngesikhathi esinqunyiwe. Hlola njalo ukuvuza, ubunzima bokujika isibambo, noma imifantu ebonakalayo. Ukufakwa esikhundleni okusheshayo kuyadingeka kuphela ezicelweni ezibaluleke kakhulu.

Lona umbuzo osebenzayo amakhasimende kaBudi, ikakhulukazi lawo aphethe izikhungo ezinkulu, avame ukuwubuza. Impendulo engcono kakhulu ithi “hlola, ungaqageli.” Uhlelo lokufaka esikhundleni olusekelwe ekhalendeni luvame ukuchitha imali. Kunalokho, kumayelana nokwazi ukuthi yini okufanele uyibheke. Eziningi zezicelo ezifana nokufaka amapayipi ekhaya noma ukunisela, lokhuukuhlolwa okusebenzayokuyindlela ejwayelekile.Amavalvu e-PVCngokuvamile ziyahluleka kancane kancane. Zikunikeza izimpawu zokuxwayisa kusenesikhathi ngaphambi kwesenzakalo esiyinhlekelele.

Izimpawu Eziyinhloko Ivalvu Edinga Ukushintshwa

Ngiqeqesha ozakwethu ukuthi babheke lezi zinto ezintathu ngesikhathi sokuhlolwa okuvamile:

1. Ukuvuza

Lesi yisibonakaliso esisobala kakhulu. Ukuvuza kungavela ezindaweni ezintathu.

• Ukuvuza kwesiqu:Amanzi ayaconsa esuka esibambweni uma usiphendula. Lokhu kusho ukuthi izindandatho ze-O-stem zigqokiwe. Kwamanye amavalvu ethu aphezulu, lawa angashintshwa, kodwa kuvalvu encane, kubonisa isikhathi sokushintsha.
• Ukuvuza Kwenyunyana:Ku-valvu yebhola le-union, uma amanzi econsa kumantongomane e-union, i-O-ring ingadinga ukushintshwa noma ukuhlaliswa kabusha.
• Ukuvuza Komzimba:Ukuqhekeka emzimbeni wevalvu uqobo. Lokhu akuvamile kodwa kubi kakhulu. Ngokuvamile kubangelwa ukubanda noma ukushayisana ngokomzimba okukhulu. Ivalvu kumele ishintshwe ngokushesha.

2. Ukuqina

Isibambo siba nzima kakhulu ukusiphendula. Lokhu kuvame ukusho ukuthi izihlalo ze-PTFE zonakaliswe yimfucumfucu noma zivuvukele ngenxa yokuchayeka kumakhemikhali. Ivalvu ayisavalwa kahle.

3. Umonakalo Obonakalayo

Bheka ukushibilika noma ukuphuzi ebusweni ngenxa yomonakalo we-UV, kanye nanoma yimiphi imifantu ebonakalayo, ikakhulukazi eduze kwamaphuzu okuxhuma.

Ingabe ama-valve ebhola e-PVC ayawohloka?

Unebhokisi lamavalvu amadala e-PVC asebehlale endaweni yokugcina impahla iminyaka eminingi. Ingabe aselungile, noma kufanele uwalahle bese u-oda amasha?

Yebo, amavalvu ebhola le-PVC angonakala, kodwa kwenzeka kancane kakhulu. Izimbangela eziyinhloko ukuchayeka kwi-UV okwenza ipulasitiki ibe buthaka, kanye nezimbozo zangaphakathi zome noma ziqine ngokuhamba kwesikhathi, ngisho noma zingasetshenziswanga.

“Ukonakala” kuyindlela enhle yokukubeka. Ivalvu ayigcini nje ngokuyeka ukusebenza ngolunye usuku. Ukusebenza kwayo kuyawohloka ngokuhamba kwesikhathi. Kwa-Pntek, ukulawulwa kwekhwalithi kuyikho konke, futhi sifunda ukuthi kwenzeka kanjani futhi kungani ukwehluleka ukwenza imikhiqizo yethu ibe ngcono. Ake sibheke izindlela ivalvu “engawohloka ngazo,” kokubili ekugcinweni nasekusetshenzisweni.

Izindlela Zokwehluleka Kwama-PVC Valve

1. Ukubola kwe-UV

Lesi yisitha esikhulu sepulasitiki ye-PVC. Imisebe ye-ultraviolet yelanga iphula amaketanga e-polymer ku-PVC. Uphawu lokuqala ukushintsha kombala, kodwa umonakalo wangempela ungowesakhiwo. Ipulasitiki ilahlekelwa ukuguquguquka kwayo futhi iba buthakathaka. Isibambo singase siqhekeke, noma umzimba ungaqhekeka ngaphansi kwengcindezi evamile. Yingakho kubaluleke kangaka ukuvikela ama-valve angaphandle.

2. Ukwehluleka Kwesivalo Nokuhluleka Kwesihlalo

Izivalo (ngokuvamile izindandatho ze-EPDM zerabha) kanye nezihlalo (PTFE) yizona zingxenye ezisengozini kakhulu.

• Kusetshenziswa:Izinhlayiya ezikhukhumezayo emanzini zingaklwebha ibhola nezihlalo, okubangela ukuvuza lapho ivalvu ivaliwe. Amakhemikhali angabangela ukuthi izivalo zivuvuke noma zibe nzima.
• Esigcinweni:Ngisho noma ziseshalofini, izindandatho ze-O zerabha zingoma kancane kancane futhi zilahlekelwe ukunwebeka kwazo eminyakeni eminingi, ikakhulukazi endaweni yokugcina impahla eshisayo neyomile.

3. Umonakalo Wokuqandisa

Amanzi ayakhula uma eqandisa. Uma amanzi evaleleke ngaphakathi kwevalvu yebhola ye-PVC evaliwe bese eqandisa, iqhwa elikhulayo lizoqhekeka umzimba. Lokhu ukwehluleka okuvamile ezinhlelweni zokunisela ezingafakwanga kahle ebusika.

Ama-ball valve alungele isikhathi esingakanani?

Uqhathanisa ama-valve e-PVC nama-valve ensimbi. Uyazi ukuthi insimbi iqinile, kodwa futhi iyabiza futhi ingagqwala. Uyazibuza ukuthi i-PVC iyindlela eqinile ngokwanele yini yokufaka isicelo sakho.

Ivalvu yebhola ye-PVC ekusetshenzisweni okuhambisanayo nokucindezela okuphansi ingahlala amashumi eminyaka. Kodwa-ke, ivalvu yebhola yethusi noma yensimbi engagqwali ingcono emazingeni okushisa aphezulu, ukucindezela okuphezulu, kanye nokusetshenziswa okunokucindezeleka okukhulu ngokomzimba.

Lona umbuzo obanzi, kodwa obaluleke kakhulu kubaphathi bokuthenga abathenga izinhlobo ezahlukene zamavalvu. Akukhona ukuthi iyiphi impahla "engcono kakhulu," kodwa ukuthi iyiphi "efanele" umsebenzi. Nakuba ubuchwepheshe bethu bungukuthiI-PVC, kubalulekile ukwethembeka ngemingcele yayo.

Ukuqhathanisa Isikhathi Sokuphila Sezinto Ze-Valve

Ake siqhathanise okulindelwe okuvamile kokuphila kwempilo kwezinhlobo ezahlukeneizinto ze-ball valvengaphansi kwezimo "ezinhle", njengamanzi ahlanzekile, umfutho ophakathi, kanye nokusetshenziswa njalo.

Izinto zeValve	Isikhathi Sokuphila Esijwayelekile	Izinzuzo Eziyinhloko	Izinkinga Eziyinhloko (Izimbangela Zokwehluleka)
I-PVC	Iminyaka eyi-15-25+	Ayigqwali, ishibhile, ilula.	Imikhawulo yokushisa/yokucindezela ephansi, ezwela i-UV, ingaqhekeka ngenxa yokushaywa.
Ithusi	Iminyaka engama-20-40+	Ukumelana okuhle kwezinga lokushisa/ukucindezela, kuqinile.	Kungagqwala ngenxa yezinhlobo ezithile zamakhemikhali amanzi (ukuhlanza), okunzima.
Insimbi engagqwali	Iminyaka engama-40-60+	Amandla amahle kakhulu, ukumelana nokushisa okuphezulu/ukucindezela, ukumelana namakhemikhali okuhle kakhulu.	Izindleko ziphezulu, zinzima. Ingasabola ezindaweni ezine-chloride ephezulu.

Ivalvu ye-PVC iyisinqumo esihle kakhulu sezinhlelo zokusebenza eziningi, ikakhulukazi ekuphathweni kwamanzi lapho insimbi ingagqwala khona. Isikhathi sayo sokuphila sihloniphekile kakhulu, ikakhulukazi uma ubheka izindleko zayo eziphansi. Ifilosofi yami ibilokhu iwukunikeza ikhambi le-PVC elingcono kakhulu. Kuzo zonke ezinye izinto, ivalvu ye-PVC esezingeni eliphezulu eyenziwe ngezinto ezingezona eziphelele eziyi-100% inikeza inani elingenakunqotshwa kanye nokuthembeka.

Isiphetho

A ama-valve ebhola e-PVC asezingeni eliphezuluIsikhathi sokuphila kwayo sincike endaweni ezungezile. Ngokufakwa okufanele kanye nokukhethwa kwezinto, ingahlinzeka ngensizakalo ethembekile iminyaka eminingi, ivame ukuhlala isikhathi eside kunemishini esekelayo.
