Wakoze akantu kawe, ariko agapfunyika kamenetse bivuze ko wapfushije umwanya, amafaranga, n'ibikoresho. Ipfundo rimwe ribi ku murongo wa PVC rishobora kuguhatira gukata igice cyose ugatangira bundi bushya.

Kugira ngo ushyireho valve y'umupira ku muyoboro wa PVC, ukoresha gusudira solvent. Ibi bikubiyemo gukata umuyoboro neza, kuwukuraho, kuwushyiramo primer ya PVC na sima ku buso bwombi, hanyuma ukabishyira hamwe ukoresheje kimwe cya kane hanyuma ugakomeza neza kugeza igihe chemical bond irangirira.

Ibi si ugukora kole gusa; ni uburyo bwa chimique buhuza pulasitiki mu gice kimwe gikomeye. Kubikora neza ntabwo ari ibintu byo kungurana ibitekerezo ku bahanga. Ni ingingo mpora nshimangira ku bafatanyabikorwa nka Budi muri Indoneziya. Abakiriya be, baba ba rwiyemezamirimo bakomeye cyangwa abacuruzi bo mu gace runaka, bashingira ku kwizerwa. Ihuriro ryangiritse si ukuvamo amazi gusa; ni ugutinda k'umushinga no guhungabanya izina ryabo. Reka turebe ibibazo by'ingenzi kugira ngo buri gikorwa kigende neza.

Ni gute wahuza valve n'umuyoboro wa PVC?

Ufite valve mu ntoki, ariko urimo kureba umuyoboro ugenda neza. Uzi ko hari ubwoko butandukanye bwo guhuza, ariko ni ubuhe bukubereye akazi kawe kugira ngo ubone sisitemu ikomeye kandi itagira amazi?

Uhuza valve n'umuyoboro wa PVC mu buryo bubiri: guhuza solvent-sudde (socket) ihoraho, ikaba ari nziza kuri PVC-to-PVC, cyangwa guhuza imigozi ikora neza, byiza cyane mu guhuza PVC n'ibice by'icyuma nk'amapompo.

Guhitamo uburyo bwiza ni intambwe ya mbere yo gushyiraho ibikoresho by'umwuga. Kuri sisitemu za PVC gusa,gusudira ibintu bishongeshani cyo gipimo ngenderwaho cy’inganda. Bikora umugozi udafite umugozi, ufatanye kandi ukomeye nk’umuyoboro ubwawo. Uburyo ni bwihuse, bwizewe, kandi buhoraho. Imiyoboro ifite imigozi ikoreshwa iyo ukeneye guhuza umurongo wa PVC yawe n’ikintu ukoresheje imigozi y’icyuma isanzwe, cyangwa iyo uteganya ko uzakenera gukuraho valve byoroshye nyuma. Ariko, ibikoresho bya pulasitiki bifite imigozi bigomba gushyirwaho witonze kugira ngo wirinde ko imiyoboro ikomera cyane. Ku miyoboro myinshi isanzwe ya PVC, buri gihe nsaba imbaraga n’uburyo bworoshye bwo guhuza imiyoboro ikoresheje solvent-welding. Iyo serivisi ari ingenzi,umupira w'uruniyo rw'ukuriiguha ibyiza byo mu isi zombi.

Ni ubuhe buryo bwiza bwo gushyiraho valve y'umupira?

Valve irapfundikiwe neza, ariko ubu umugozi wayo ugonga urukuta ntushobora gufunga. Cyangwa washyizeho valve y'ubumwe bw'imvange ikomeye cyane ku nkokora ku buryo udashobora kuyishyiramo urufunguzo.

"Uburyo bwiza" bwo gushyiraho valve y'umupira ni uguteganya uko ikora. Ibi bivuze ko ugomba kubanza gukoresha icyuma cyumye kugira ngo urebe neza ko umugozi ufite umurambararo wuzuye wa dogere 90 kandi ko utubuto tw'umugozi dushobora kuboneka neza kugira ngo dukomeze kubungabungwa mu gihe kizaza.

Gushyiramo neza birenga gusaikirango kidasohoka; ni imikorere y'igihe kirekire. Aha niho umunota umwe wo gutegura ugabanya isaha yo gusubiramo. Mbere yo gufungura primer, shyira valve aho yagenewe hanyuma uzunguze umugozi. Ese igenda mu buryo bw'ubwisanzure kuva ifunguye kugeza ifunze neza? Niba atari byo, ugomba guhindura icyerekezo cyayo. Icya kabiri, niba ukoresha ikoranabuhanga ryiza cyanevalve y'ubumwe bw'ukuriKimwe n'iyacu muri Pntek, ugomba kwemeza ko ushobora kubona utubuto twa union. Intego y'utu tubuto ni ukugira ngo umubiri wa valve ukurweho nta gukata umuyoboro. Buri gihe nibutsa Budi kubwira abakiriya be ibi: niba udashobora gupfuka utubuto, uba waratsinze intego yose ya valve. Tekereza ko ari ugushyiraho atari uyu munsi gusa, ahubwo no ku muntu ugomba kuyitunganya nyuma y'imyaka itanu.

Ese valve za PVC zigana mu cyerekezo?

Uba witeguye gukoresha sima, ariko urahagarara, ushakisha umwambi utemba ku gice cy'umuyoboro w'amashanyarazi. Uzi ko gushyiramo umuyoboro w'amashanyarazi inyuma byaba ari ikosa rikomeye kandi rihenze.

Oya, valve isanzwe ya PVC ntabwo igana mu cyerekezo kimwe; igana mu cyerekezo kimwe. Ikoresha imiterere ingana ifite ibifunga ku mpande zombi, bigatuma ifunga neza amazi ava mu cyerekezo kimwe. "Icyerekezo" cyonyine cyo guhangayikishwa ni icyerekezo cyayo kugira ngo umuntu agere ku mugozi.

Iki ni ikibazo cyiza kandi gikunze kugaragara. Ubwitonzi bwawe bufite ishingiro kuko izindi valve, nkavalve zo kugenzuracyangwa valve z'isi, zerekeza mu cyerekezo rwose kandi zizananirwa nizishyirwa inyuma. Zifite umwambi ugaragara ku mubiri kugira ngo ukuyobore.valve y'umupiraIcyakora, bikora mu buryo butandukanye. Imbere yayo ni umupira woroshye ufite umwobo unyuramo, uzenguruka kugira ngo upfundike ku ntebe. Kubera ko hari intebe ku ruhande rwo hejuru n'urwo hasi rw'umupira, ikora agapfundikizo gakomeye uko igitutu cyaba giturutse kose. Bityo, ushobora kuruhuka. Ntushobora gushyiraho valve isanzwe y'umupira "isubira inyuma" mu bijyanye n'amazi. Iyi miterere yoroshye kandi ikomeye ni imwe mu mpamvu ikunzwe cyane. Ibande gusa ku kuyishyira aho ifata n'amapine bikoroha kuyibona.

Ni gute valve za PVC zizewe?

Wabonye imvange ya PVC ihendutse kandi itazwi neza icika cyangwa ivamo amazi nyuma y'umwaka umwe gusa, bigatuma wibaza ku bikoresho ubwabyo. Uratekereza niba wakoresha imvange y'icyuma ihenze cyane.

Valve z'umupira za PVC nziza cyane ni nziza cyane kandi zishobora kumara imyaka ibarirwa muri za mirongo. Ubuzima bwazo buterwa n'ubwiza bw'ibikoresho fatizo (PVC idafite ubwandu cyangwa ikoreshwa mu kongera gukoreshwa), uburyo bwo gukora neza, no gushyiraho neza. Valve nziza ikunze kumara igihe kirekire kurusha sisitemu irimo.

Kwizerwa kwaValve y'umupira ya PVCbishingira ku cyo ikozemo n'uko ikorwa. Iyi ni yo shingiro ry'imitekerereze yacu muri Pntek.

Ni iki kigena ubwizerwe?

• Ubwiza bw'ibikoresho:Dushimangira ko dukoreshaPVC idafite ubuziranenge 100%. Amavali menshi ahendutse akoresha ibikoresho byasubiwemo cyangwa byuzuza, bigatuma plastiki icika intege kandi ikagira ingaruka mbi iyo ihuye n'igitutu cyangwa imirasire ya UV. Virgin PVC itanga imbaraga nyinshi kandi irwanya imiti.
• Uburyo bwo gukora ibintu neza:Gukora kwacu mu buryo bwikora bituma buri vali imwe. Umupira ugomba kuba ufite uruziga rwose kandi intebe zikaba nziza cyane kugira ngo habeho agapfukamunwa gakomeye. Dupima vali zacu ku gitutu ku rugero rwo hejuru cyane kuruta uko bazabona mu kibuga.
• Igishushanyo mbonera cyo kuramba:Ibintu nk'umubiri w'ubumwe nyakuri, impeta za EPDM cyangwa FKM O, hamwe n'igishushanyo mbonera cy'igiti gikomeye byose bigira uruhare mu kumara igihe kirekire. Iri ni ryo tandukaniro riri hagati y'igice cyo guta n'umutungo w'igihe kirekire.

Valve ya PVC yakozwe neza kandi ishyizwemo neza si ikintu kidakomeye; ni igisubizo kiramba, kidahura n'ingufu, kandi gihendutse kuri
