Umthengi wakho ucela isiqinisekiso sobomi bonke kwinkqubo yakhe entsha yokunkcenkceshela. Kufuneka wazi ukuba iivalvu zebhola zePVC ziya kuhlala ixesha elingakanani ukuze ulawule ulindelo lwakhe ngokuchanekileyo.

Ivalvu yebhola yePVC esemgangathweni ophezulu inokuhlala iminyaka emininzi, ide ifikelele kwiminyaka engama-20 nangaphezulu, phantsi kweemeko ezifanelekileyo. Ixesha lokuphila lixhomekeke kakhulu ekuchaphazekeni kwe-UV, ukudibana kwamakhemikhali, uxinzelelo lwamanzi, kunye nokuba isetyenziswa kangaphi.

Lo ngumbuzo endiwuxoxa rhoqo namaqabane anjengoBudi wase-Indonesia. Kufuneka anike abathengi bakhe ulwazi oluthembekileyo, oluqala kubakhi abakhulu ukuya kubathengisi abancinci. Impendulo ayilonani linye. Ixesha lokuphila kwevalvu yebhola ye-PVC lixhomekeke kwizinto ezininzi ezibalulekileyo. Ukuqonda ezi zinto kubalulekile ekukhetheni ivalvu efanelekileyo nasekubekeni ulindelo oluyinyani kubasebenzisi bokugqibela. Imalunga nokuqinisekisa ukuba imveliso isebenza njengoko kuthembisiwe ubomi bayo bonke benkonzo.

Ingakanani ixesha lokuphila kwevalvu yebhola yePVC?

Ukhetha iivalvu zeprojekthi ebalulekileyo. Ubona amabango omenzi wobomi beminyaka elikhulu kwiipayipi zePVC, kodwa uyazi ukuba ivalvu inzima kakhulu kwaye iza kusilela kungekudala.

Ixesha lokuphila lidla ngokuxhomekeka kwiindawo zayo ezihambayo kunye nezitywini. Nangona umzimba wePVC unokuhlala iminyaka engaphezu kwama-50, izitywini (EPDM okanye iFPM) kunye nesihlalo (PTFE) ziya kuqala ziguge, zihlala ziphakathi kweminyaka emi-5 ukuya kwengama-20 kuxhomekeke kwindlela ezisetyenziswa ngayo.

Umzimba we-PVC wevalvu eyenziwe kakuhle uhlala ixesha elide. Phantsi kweemeko eziqhelekileyo, zigqunywe okanye zingaphakathi kude nelanga, zinokuhlala amashumi eminyaka, njengombhobho we-PVC. Nangona kunjalo, ivalvu ayisiyoplastiki nje kuphela; sisixhobo soomatshini. Umbuzo wokwenyani malunga nobude bobomi beendawo ezihambayo nezitywinayo.

Izinto Eziphambili Ezithintela Ubude Bobomi

Nazi izinto eziphambili ezigqiba ukuba izitywino kunye nezihlalo ziya kuhlala ixesha elingakanani. Zezona ndawo zibuthathaka kuyo nayiphi na inkqubo yevalvu.

I-Factor	Impembelelo kubude bobomi	Indlela Yokuphucula Ubomi
Ukuvezwa kwe-UV	Yenza i-PVC ibe buthathaka, iyenza buthathaka imivalo.	Faka phantsi komhlaba, kwibhokisi yevalvu, okanye upende ngepeyinti esekwe kwilatex.
Iikhemikhali	Iikhemikhali ezirhabaxa ziyazonakalisa izinto zokutywina (EPDM, FPM).	Khetha izinto zokutywina ezifanelekileyo zekhemikhali (umz., i-FPM yeeoyile).
Ukutshintshatshintsha koxinzelelo	Ihamile yamanzi okanye iispikes zoxinzelelo ezingaguqukiyo zixinzelela umzimba wevalvu kunye nezitywini.	Faka izixhobo zokuthintela ihamile yamanzi kwaye usebenze ngaphantsi komlinganiselo woxinzelelo ophezulu.
Ubushushu	Amaqondo obushushu aphezulu athambisa i-PVC aze akhawulezise ukuguga kwetywina.	Sebenzisa ivalvu ye-CPVC emanzini ashushu kwaye uhlale ngaphakathi kwemida yobushushu.
Ukuphindaphinda komjikelo	Ukuvulwa/ukuvalwa rhoqo kuyayigugisa isihlalo sebhola kunye nezitywini zesiqu.	Kwindlela esebenza ngayo yonke into, khetha ivalvu eyenzelwe ukwenza izinto ngokuzenzekelayo.

Ivalvu esetyenziswa kumgca wamanzi ococekileyo nophantsi koxinzelelo inokuhlala amashumi eminyaka. Ivalvu efanayo kumgca wokucubungula iikhemikhali wangaphandle inokufuna ukutshintshwa kwezitywino zayo rhoqo emva kweminyaka embalwa.

Kufuneka uyitshintshe kangaphi ivalvu yePVC?

Uneevalvu ezininzi kwindawo yakho. Ngaba kufuneka uzitshintshe ngexesha elithile, okanye ulinde ukuba zingasebenzi? Ukungasebenzi kakuhle okungalindelekanga kunokubangela izikhukula ezinkulu.

Kufuneka uyitshintshe ivalvu yePVC xa ibonisa iimpawu zokungasebenzi kakuhle, kungekhona ngexesha elimiselweyo. Hlola rhoqo ukuba akukho kuvuza, ubunzima bokujika isiphatho, okanye imingxunya ebonakalayo. Ukutshintshwa kwangoko kuyadingeka kuphela kwiindawo ezibaluleke kakhulu.

Lo ngumbuzo osebenzayo abathengi bakaBudi, ingakumbi abo balawula izakhiwo ezinkulu, abadla ngokuwubuza. Impendulo engcono kukuba “hlola, ungaqashi.” Ishedyuli yokutshintsha esekelwe kwikhalenda idla ngokuchitha imali. Endaweni yoko, malunga nokwazi into omawuyijonge. Kwiizicelo ezininzi ezifana nemibhobho yamanzi okanye ukunkcenkceshela ekhaya, okuuhlolo olusebenzayoyindlela eqhelekileyo.Iivalvu zePVCZihlala zisilela kancinci kancinci. Zikunika imiqondiso yokulumkisa kudala ngaphambi kwesiganeko esibi.

Iimpawu ezibalulekileyo zeValve ezifuna ukutshintshwa

Ndiqeqesha amaqabane ethu ukuba ajonge ezi zinto zintathu ngexesha lokuhlolwa rhoqo:

1. Ukuvuza

Olu lolona phawu lucacileyo. Ukuvuza kungavela kwiindawo ezintathu.

• Ukuvuza kwesiqu:Amanzi ayathontsiza esuka kwisibambo xa usijika. Oku kuthetha ukuba ii-stem O-rings zinxityiwe. Kwezinye iivalvu zethu eziphezulu, ezi zinokutshintshwa, kodwa kwivalvu encinci, ibonisa ixesha lokutshintshwa.
• Ukuvuza kweManyano:Kwivalvu yebhola ye-union, ukuba amanzi aphuma kwiinati ze-union, i-O-ring ingadinga ukutshintshwa okanye ukuphinda ihlalwe.
• Ukuvuza komzimba:Ukuqhekeka komzimba wevalvu ngokwawo. Oku kunqabile kodwa kuyingozi kakhulu. Kudla ngokubangelwa kukuqandisa okanye ukungqubana okukhulu ngokomzimba. Ivalvu kufuneka itshintshwe ngoko nangoko.

2. Ukuqina

Isiphatho siba nzima kakhulu ukusijika. Oku kuthetha ukuba izitulo ze-PTFE zonakele ngenxa yenkunkuma okanye zidumbile ngenxa yokuvezwa ziikhemikhali. Ivalvu ayisavalwa kakuhle.

3. Umonakalo Obonakalayo

Khangela ukuba akukho khrikhi okanye tyheli kumphezulu ngenxa yomonakalo we-UV, kwaye nakuphi na ukuqhekeka okubonakalayo, ingakumbi kwiindawo zokudibanisa.

Ngaba iivalvu zebhola zePVC ziyawohloka?

Unebhokisi yeevalvu zePVC ezindala ebezihleli kwindawo yokugcina impahla kangangeminyaka. Ngaba zisalungile, okanye kufuneka uzilahle uze u-ode ezintsha?

Ewe, iivalvu zebhola zePVC zinokonakala, kodwa kwenzeka kancinci kakhulu. Izizathu eziphambili kukuvezwa yi-UV okwenza iplastiki ibe buthathaka, kwaye izitywino zangaphakathi zome okanye ziqine ngokuhamba kwexesha, nokuba azisetyenziswanga.

“Ukonakala” yindlela entle yokuyibeka. Ivalvu ayiyeki nje ukusebenza ngenye imini. Ukusebenza kwayo kuyawohloka ngokuhamba kwexesha. KwaPntek, ulawulo lomgangatho lubaluleke kakhulu, kwaye sifunda indlela kunye nesizathu sokuba kwenzeke ukungaphumeleli ukuze senze iimveliso zethu zibe ngcono. Makhe sijonge iindlela ivalvu “enokonakala” ngazo, kokubini kwindawo yokugcina nasekusetyenzisweni.

Iindlela zokusilela kweeValve zePVC

1. Ukubola kwe-UV

Olu lutshaba oluphambili lweplastiki yePVC. Imitha ye-ultraviolet yelanga iyawaphula amatyathanga epolymer kwiPVC. Uphawu lokuqala kukutshintsha kombala, kodwa umonakalo wokwenyani ungowolwakhiwo. Iplastiki ilahlekelwa bububhetyebhetye bayo kwaye iba buthathaka. Isiphatho sinokuqhekeka, okanye umzimba ungaqhekeka phantsi koxinzelelo oluqhelekileyo. Yingakho kubaluleke kangaka ukukhusela iivalvu zangaphandle.

2. Ukusilela kweSeal kunye neSihlalo

Izitywino (ngokuqhelekileyo ii-EPDM zerabha ze-O-rings) kunye nezihlalo (PTFE) zezona ndawo zisengozini kakhulu.

• Isetyenziswa:Amasuntswana arhabaxa emanzini anokukrwela ibhola kunye nezihlalo, nto leyo ebangela ukuvuza xa ivalvu ivaliwe. Iikhemikhali zinokubangela ukuba izitywini zidumbe okanye zibe lukhuni.
• Kwindawo yokugcina:Nokuba sele ziseshelufini, ii-O-rings zerabha zingoma kancinci kancinci kwaye ziphelelwe bubuthambile bazo kangangeminyaka emininzi, ingakumbi kwindawo yokugcina impahla eshushu neyomileyo.

3. Umonakalo obandayo

Amanzi ayakhula xa ebanda. Ukuba amanzi avalelwe ngaphakathi kwevalvu yebhola yePVC evaliweyo aze aqine, umkhenkce okhulayo uya kuqhekeka umzimba. Oku kukusilela okuqhelekileyo kwiinkqubo zokunkcenkceshela ezingafakwanga kakuhle ebusika.

Iivalvu zebhola zilungele ixesha elingakanani?

Uthelekisa iivalvu zePVC neevalvu zesinyithi. Uyazi ukuba isinyithi siqinile, kodwa sibiza kakhulu kwaye sinokubola. Uyazibuza ukuba iPVC ilukhetho oluqinileyo ngokwaneleyo na kwisicelo sakho.

Ivalvu yebhola yePVC esetyenziswa ngendlela ehambelanayo nengenaxinzelelo ingahlala amashumi eminyaka. Nangona kunjalo, ivalvu yebhola yebrass okanye yentsimbi engatyiwayo ingcono kumaqondo obushushu aphezulu, uxinzelelo oluphezulu, kunye nokusetyenziswa okunoxinzelelo olukhulu lomzimba.

Lo ngumbuzo obanzi, kodwa ubaluleke kakhulu kubaphathi bokuthenga abathenga iintlobo ezahlukeneyo zeevalvu. Akubhekiselele ekubeni zeziphi izinto "ezilungileyo," kodwa zeziphi "ezifanelekileyo" kulo msebenzi. Nangona ubuchule bethu buI-PVC, kubalulekile ukunyaniseka ngemida yayo.

Ukuthelekisa ubomi bezinto zeValve

Masithelekise ulindelo oluqhelekileyo lobomi bemihla ngemihla eyahlukeneyoizixhobo zevalvu yebholaphantsi kweemeko "ezilungileyo", ezinje ngamanzi acocekileyo, uxinzelelo oluphakathi, kunye nokusetyenziswa rhoqo.

Izinto zeValve	Ixesha eliqhelekileyo lobomi	Iingenelo eziphambili	Izinto Ezingalunganga Eziphambili (Izizathu Zokusilela)
I-PVC	Iminyaka eli-15-25 nangaphezulu	Ayinamhlwa, ixabiso liphantsi, ilula.	Imida yobushushu/uxinzelelo ephantsi, enobuthathaka kwi-UV, inokuqhekeka ngenxa yokubetha.
Intsimbi yobhedu	Iminyaka engama-20 ukuya kwengama-40 nangaphezulu	Ukumelana kakuhle nobushushu/uxinzelelo, kuqinile.	Ingabola ngenxa yezinye iikhemikhali zamanzi (ukususwa kwe-zincification), inzima.
Yenziwe ngentsimbi eshayinayo	Iminyaka engama-40-60 nangaphezulu	Amandla agqwesileyo, ukumelana nobushushu obuphezulu/uxinzelelo, ukumelana neekhemikhali okugqwesileyo.	Ixabiso liphezulu, linzima. Lisenokubola kwiindawo ezine-chloride eninzi.

Ivalvu yePVC lukhetho oluhle kakhulu kwiintlobo ngeentlobo zezicelo, ingakumbi kulawulo lwamanzi apho isinyithi singabola khona. Ixesha layo lokuphila lihloniphekile kakhulu, ingakumbi xa ucinga ngexabiso layo eliphantsi. Ifilosofi yam ibisoloko ikukubonelela ngesisombululo sePVC esingcono kakhulu.
