Ugqibile ukwenza umsebenzi wakho, kodwa isitywino esivuzayo sithetha ukuchitha ixesha, imali, kunye nezinto zokwakha. Ilungu elinye elibi kumgca we-PVC linokukunyanzela ukuba usike lonke icandelo uze uqale phantsi.

Ukufaka ivalvu yebhola kumbhobho wePVC, usebenzisa i-solvent welding. Oku kuquka ukusika umbhobho ngokucocekileyo, ukususa iimbumbulu, ukufaka i-primer yePVC kunye nesamente kuzo zombini iindawo, uze uzityhale kunye ngekota uze uzibambe ngokuqinileyo de kube kuhlangana kweekhemikhali.

Oku akupheleli nje ekuncamathiseleni; yinkqubo yeekhemikhali edibanisa iplastiki ibe yinto enye eqinileyo. Ukuyilungisa akuxoxiswana ngayo kwiingcali. Yingongoma endisoloko ndiyigxininisa kumaqabane anjengoBudi e-Indonesia. Abathengi bakhe, nokuba bangabakhi abakhulu okanye abathengisi basekuhlaleni, baxhomekeke ekuthembekeni. I-joint ephukileyo ayisiyonto nje evuzayo; kukulibaziseka kweprojekthi kwaye kuyonakalisa udumo lwabo. Masiqwalasele imibuzo ebalulekileyo ukuze senze ukufakelwa ngakunye kube yimpumelelo.

Uyiqhagamshela njani ivalvu kumbhobho wePVC?

Unevalvu esandleni sakho, kodwa ujonge umbhobho ogudileyo. Uyazi ukuba kukho iintlobo ezahlukeneyo zoqhagamshelo, kodwa yeyiphi efanelekileyo kumsebenzi wakho ukuqinisekisa inkqubo eqinileyo, engenamanzi?

Uqhagamshela ivalvu kumbhobho wePVC ngenye yeendlela ezimbini: uqhagamshelo oluhlala luhleli lwe-solvent-weld (socket), olulungele iPVC-to-PVC, okanye uqhagamshelo olunemisonto olulungiselelwayo, olulungele ukudibanisa iPVC nezinto zesinyithi ezifana neepompo.

Ukukhetha indlela elungileyo linyathelo lokuqala lokufakela ngobuchwephesha. Kwiinkqubo ezisebenza ngePVC ngokupheleleyo,ukuwelda isinyibilikisingumgangatho weshishini. Yenza i-joint engenamthungo, edibeneyo eqinileyo njengombhobho ngokwawo. Le nkqubo ikhawuleza, ithembekile, kwaye ingunaphakade. Uqhagamshelo olunemisonto lusetyenziswa xa ufuna ukuqhagamshela umgca wakho wePVC kwinto ethile ngemisonto yesinyithi ekhoyo, okanye xa ulindele ukuba kufuneka uyisuse ngokulula kamva. Nangona kunjalo, izixhobo zeplastiki ezinemisonto kufuneka zifakwe ngononophelo ukuze kuthintelwe ukuqhekeka ekuqineni kakhulu. Kwiipayipi ezininzi zePVC eziqhelekileyo, ndisoloko ndicebisa amandla kunye nokulula koqhagamshelo lwe-solvent-weld. Xa ukulungiswa kubalulekile,ivalvu yebhola yomanyano lokwenyaniikunika ezona zinto zilungileyo kuzo zombini ihlabathi.

Yeyiphi indlela efanelekileyo yokufaka ivalvu yebhola?

Ivalvu incamatheliswe kakuhle, kodwa ngoku isiphatho sibetheka eludongeni kwaye asikwazi ukuvala. Okanye ufake ivalvu yomanyano yokwenyani eqinileyo engqinibeni kangangokuba awukwazi ukuyifaka isikrufu.

"Indlela echanekileyo" yokufaka ivalvu yebhola kukucwangcisa ukusebenza kwayo. Oku kuthetha ukuba kufuneka ifakelwe elomileyo kuqala ukuqinisekisa ukuba isiphatho sinendawo yokujika epheleleyo engama-90-degree kwaye ii-union nuts ziyafikeleleka ngokupheleleyo ukuze zigcinwe ixesha elizayo.

Ufakelo oluphumeleleyo ludlula njeisitywino esingavuziyo; imalunga nokusebenza kwexesha elide. Kulapho umzuzu wokucwangcisa ugcina khona iyure yokuphinda usebenze. Ngaphambi kokuba uvule i-primer, beka ivalvu kwindawo elungiselelwe yona kwaye ujike isiphatho. Ngaba ihamba ngokukhululekileyo ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo? Ukuba akunjalo, kufuneka ulungise indlela eyiyo. Okwesibini, ukuba usebenzisa i-high qualityivalvu yomanyano lokwenyaniNjengeyethu ePntek, kufuneka uqinisekise ukuba uyakwazi ukufikelela kwii-union nuts. Injongo yezi valves kukuvumela ukususwa komzimba we-valve ngaphandle kokusika umbhobho. Ndihlala ndikhumbuza uBudi ukuba axelele abathengi bakhe oku: ukuba awukwazi ukufumana isikrufu kwii-nuts, woyisile yonke injongo ye-valve. Cinga ngayo njengokufakela kungekuphela nje namhlanje, kodwa kumntu omele ayilungise kwiminyaka emihlanu ezayo.

Ngaba iivalvu zebhola zePVC zibhekiselele kwicala elithile?

Ulungele ukusebenzisa isamente, kodwa uyama kancinci, ukhangela umcibisholo ohambayo emzimbeni wevalvu. Uyazi ukuba ukuncamathisela ivalvu ebhekisa kwicala elingasemva kuya kuba yimpazamo enkulu nebiza kakhulu.

Hayi, ivalvu yebhola yePVC eqhelekileyo ayijongi kwicala; ijongi kwicala eliphakathi. Isebenzisa uyilo olulinganayo olunezitywino kumacala omabini, oluvumela ukuba ivale ukuhamba ngokulinganayo ukusuka kwicala ngalinye. "Icala" elilodwa ekufuneka ukhathazeke ngalo kukujongisisa kwayo ngokwasemzimbeni ukufikelela kwisibambo.

Lo ngumbuzo omhle noqhelekileyo. Isilumkiso sakho sifanelekile kuba ezinye iivalvu, ezifanaiivalvu zokujongaokanye iivalvu zeglobe, zijolise ngqo kwicala kwaye ziya kusilela ukuba zifakwe ngasemva. Zinetolo elicacileyo emzimbeni ukuze likukhokele.ivalvu yebholaNangona kunjalo, isebenza ngendlela eyahlukileyo. Umbindi wayo yibhola elula enomngxuma kuyo, ejikeleza ukuze ivalwe isihlalo. Ekubeni kukho isihlalo kwicala elingaphezulu nelisezantsi lebhola, idala isitywino esiqinileyo nokuba uxinzelelo luvela phi. Ngoko ke, ungaphumla. Awunakufaka ivalvu yebhola eqhelekileyo "ngasemva" ngokubhekiselele ekuhambeni. Olu luyilo lulula, oluqinileyo sesinye sezizathu zokuba zithandwa kangaka. Gxila nje ekuyibekeni ukuze kube lula ukufikelela kwisibambo kunye neeyunithi.

Zithembeke kangakanani iivalvu zebhola zePVC?

Ubone ivalvu yePVC engabizi kakhulu, engaziwayo iqhekeka okanye ivuza emva konyaka nje omnye, nto leyo ekwenza uzibuze ngesixhobo ngokwaso. Uzibuza ukuba kufuneka usebenzise ivalvu yesinyithi ebiza kakhulu na.

Iivalvu zebhola zePVC ezikumgangatho ophezulu zithembeke kakhulu kwaye zinokuhlala amashumi eminyaka. Ubomi bazo buxhomekeke kumgangatho wezinto eziluhlaza (i-virgin vs. i-PVC esetyenzisiweyo), ukuchaneka kokwenziwa, kunye nokufakelwa okufanelekileyo. Ivalvu esemgangathweni idla ngokuhlala ixesha elide kunenkqubo ekuyo.

Ukuthembeka kweIvalvu yebhola yePVCkuxhomekeke kwinto eyenziwe ngayo nendlela eyenziwe ngayo. Le yeyona ngcamango yethu kwiPntek.

Yintoni Emisela Ukuthembeka?

• Umgangatho wezinto ezibonakalayo:Sigxininisa ekusebenziseniI-PVC eyi-100% eyi-virginIivalvu ezininzi ezingabizi kakhulu zisebenzisa izinto ezisetyenzisiweyo okanye ezizalisa izinto, nto leyo eyenza iplastiki ibe buthathaka kwaye ikwazi ukungasebenzi kakuhle xa iphantsi koxinzelelo okanye ichaphazeleka yi-UV. I-Virgin PVC inika amandla angcono kunye nokumelana neekhemikhali.
• Ukuchaneka kweMveliso:Imveliso yethu ezenzekelayo iqinisekisa ukuba ivalvu nganye iyafana. Ibhola kufuneka ibe yingqukuva ngokugqibeleleyo kwaye izihlalo zigudileyo ngokugqibeleleyo ukuze zenze isitywino esiqinileyo njengebhamuza. Sivavanya iivalvu zethu ngoxinzelelo ukuya kwinqanaba eliphezulu kakhulu kunalo naliphi na abaya kulibona ebaleni.
• Uyilo Lokuphila Ixesha Elide:Iimpawu ezifana nomzimba womanyano lokwenyani, ii-EPDM okanye ii-FKM O-rings, kunye noyilo oluqinileyo lwesiqu zonke zinegalelo kubomi obude benkonzo. Lo ngumahluko phakathi kwento elahliweyo kunye nempahla yexesha elide.

Ivalvu yePVC eyenziwe kakuhle, efakwe kakuhle ayilokhonkco libuthathaka; sisisombululo esihlala ixesha elide, esimelana nokugqwala, nesingabizi mali ininzi.
