Ufite valve n'umuyoboro bikwiye, ariko ikosa rimwe rito mu gihe cyo gushyiraho rishobora gutuma habaho gucika burundu. Ibi bigutera guhagarika byose no gutangira bundi bushya, utakaza umwanya n'amafaranga.

Kugira ngo ushyireho valve y'umupira ku muyoboro wa PVC, ugomba kubanza guhitamo ubwoko bukwiye bwo kuyihuza: valve ifite imigozi ikoresha kaseti ya PTFE cyangwa valve ifite aho ihurira ikoresheje primer ya PVC na sima. Gutegura neza n'ubuhanga ni ingenzi kugira ngo ifunze idasohoka.

Intsinzi y'akazi kose k'ububombo iterwa no guhuza. Kubikemura neza ni ikintu nkunda kuganiraho n'abafatanyabikorwa nka Budi muri Indoneziya, kuko abakiriya be bahura nabyo buri munsi. Valve iva hafi ya yose ntabwo ari uko valve ubwayo ari mbi; ni uko ingingo itakozwe neza. Inkuru nziza ni uko gukora agapfundikizo gahoraho byoroshye iyo ukurikije intambwe nke zoroshye. Amahitamo y'ingenzi uzakora ni uguhitamo niba ukoresha insinga cyangwa kole.

Ni gute wahuza valve y'umupira na PVC?

Urabona valve zifite imigozi n'iz'isoko zihari. Guhitamo idakwiriye bivuze ko ibice byawe bitazakwira, bigahagarika umushinga wawe kugeza igihe uzabona valve ikwiye.

Uhuza valve y'umupira na PVC mu buryo bubiri. Ukoresha imiyoboro y'imigozi (NPT cyangwa BSP) kuri sisitemu zishobora gukenera gusenywa, cyangwa imiyoboro y'isoketi (socket weld) kugira ngo ubone umugozi uhoraho kandi ufatanye.

Intambwe ya mbere ni uguhuza valve yawe n'imiyoboro yawe. Niba imiyoboro yawe ya PVC isanzwe ifite impera z'imigozi y'abagabo, ukeneye valve y'abagore ifite imigozi. Ariko ku mirimo myinshi mishya yo kuvomera amazi, cyane cyane iyo kuhira cyangwa mu bidendezi, uzakoresha valve z'imigozi na sima. Buri gihe nsanga ari ingirakamaro iyo itsinda rya Budi ryeretse abakiriya imbonerahamwe kugira ngo basobanure neza amahitamo. Uburyo bugenwa na valve ufite. Ntushobora gukoresha valve y'imigozi cyangwa kuyishyiramo valve y'imigozi. Uburyo busanzwe kandi buhoraho bwo guhuza PVC na PVC nisoketicyangwagusudira ibintu bishongesha, uburyo. Ubu buryo ntibuhuza ibice gusa; ahubwo buvanga valve n'umuyoboro mu buryo bwa shimi mu gice kimwe cya pulasitiki gifite umugozi, gikomeye cyane kandi cyizewe iyo gikozwe neza.

Isesengura ry'uburyo bwo guhuza

Ese hari uburyo bwiza bwo gushyiraho valve y'umupira?

Utekereza ko valve ikora kimwe mu cyerekezo icyo ari cyo cyose. Ariko kuyishyiramo icyerekezo kitari cyo bishobora kubuza urujya n'uruza rw'amazi, bigatera urusaku, cyangwa bigatuma bidashoboka kuyitunganya nyuma.

Yego, hari uburyo bwiza. Valve igomba gushyirwaho aho umugozi wayo ugera, utwuma twa union (kuri union valve) tugashyirwa ku buryo bworoshye kuyikuramo, kandi tugahora turi ahantu hafunguye mu gihe cyo kuyitera kole.

Utuntu duto duto dutandukanya imikorere y’umwuga n’iy’abatarabigize umwuga. Ubwa mbere,icyerekezo cy'aho ukoreraMbere yo gukoresha kole ikintu icyo ari cyo cyose, shyira valve hanyuma urebe neza ko umugozi ufite umwanya uhagije wo guhindura dogere 90 zose. Nabonye valves zishyizwe hafi cyane y'urukuta ku buryo umugozi ushobora gufungura hagati gusa. Bisa n'aho byoroshye, ariko ni ikosa risanzwe. Icya kabiri, kuri valves zacu za True Union, dushyiramo utwuma tubiri twa union. Izi zakozwe kugira ngo uzikuremo hanyuma uvane agace ka valve mu muyoboro kugira ngo zikoreshwe. Ugomba gushyiraho valve ifite umwanya uhagije wo kurekura utwuma. Intambwe y'ingenzi cyane ariko, ni uko valve imeze mu gihe cyo kuyishyiraho.

Intambwe y'ingenzi cyane: Guma ufungura valve

Iyo urimo gusudira ibyuma bisukura (socket valve), icyuma gifungaugombaIfunguye neza. Imisemburo iri mu gice cyo hejuru na sima yagenewe gushonga PVC. Iyo valve ifunze, iyi misemburo ishobora gufatwa mu gice cyo hejuru cy'imashini hanyuma igashyira umupira mu mwobo w'imbere mu cyuma hakoreshejwe imiti. Valve izafungwa burundu. Ndabwira Budi ko iyi ari yo mpamvu ya mbere itera "ikosa rishya rya valve." Si ikibazo cya valve; ni ikosa ryo gushyiramo rishobora kwirindwa 100%.

Ni gute washyira kole kuri valve y'umupira wa PVC?

Ushyira kole hanyuma ugafatana ibice, ariko ingingo irananirwa iyo urimo gukanda. Ibi bibaho kuko "gufatana" mu by'ukuri ari inzira ya shimi isaba intambwe zihariye.

Kugira ngo ushyireho kole neza ku gikoresho cy'umupira cya PVC, ugomba gukoresha uburyo bwa primer y'intambwe ebyiri na sima. Ibi bikubiyemo gusukura, gushyira primer y'umuhengeri ku buso bwombi, hanyuma ugashyiraho sima ya PVC mbere yo kubihuza no kubyizunguza.

Iyi nzira yitwa gusudira solvent, kandi ikora umugozi ukomeye kurusha umuyoboro ubwawo. Gusimbuka intambwe ni garanti y'amazi azava mu gihe kizaza. Dore inzira dutoza abakwirakwiza Budi gukurikiza:

1. Gufata neza byumye mbere na mbere.Menya neza ko umuyoboro wo hasi uri imbere mu gice cy'isoko rya valve.
2. Sukura Ibice Byombi.Koresha igitambaro gisukuye kandi cyumye kugira ngo uhanagure umwanda cyangwa ubushuhe ubwo aribwo bwose buturutse inyuma y'umuyoboro n'imbere mu gice cy'imashini igabanya ubushyuhe.
3. Shyiraho Primer.Koresha icyuma gikingira kugira ngo usige agapira ka PVC inyuma y'umuyoboro n'imbere mu mwobo. Agapira gasukura ubuso hakoreshejwe imiti maze gatangira koroshya plastiki. Iyi ni intambwe yasimbuwe cyane kandi y'ingenzi cyane.
4. Shyiramo sima.Mu gihe primer ikiri nto, shyira sima ya PVC ku bice bya primer. Ntugakoreshe cyane, ariko menya neza ko itwikiriye neza.
5. Huza hanyuma uhindure.Suka umuyoboro ako kanya mu mwobo kugeza ubwo ugiye hasi. Uko urimo kuwusunika, hindura kimwe cya kane. Uku kugenda gukwirakwiza sima neza kandi gukuraho utubumbe twose tw’umwuka twafashwe.
6. Komeza ukire.Fata ingingo ikomeye mu mwanya wayo mu gihe cy'amasegonda 30 kugira ngo wirinde ko umuyoboro usubira inyuma. Ntukore ku ngingo cyangwa ngo uyivange byibuze iminota 15, kandi ureke ikire neza ukurikije amabwiriza y'uruganda rwa sima mbere yo gushyiramo ingufu kuri sisitemu.

Ni gute wakora uburyo bworoshye bwo guhinduranya umupira wa PVC?

Valve yawe nshya irakomeye cyane, kandi uhangayikishijwe no gucika umugozi. Ubu bukomere bushobora gutuma utekereza ko valve ifite inenge mu gihe mu by'ukuri ari ikimenyetso cy'ubwiza.

Valve nshya ya PVC nziza cyane irakomeye kuko intebe zayo za PTFE zituma umupira upfundikirwa neza kandi uhamye. Kugira ngo woroherwe, koresha agace kari ku gice cy'inyuma cy'umukono kugira ngo urusheho kuwucamo.

Iki kibazo ndakibaza buri gihe. Abakiriya bakira Pntek yacuvalvekandi bakavuga ko bigoye cyane kubizunguruka. Ibi ni ukubigambiriye. Impeta z'umweru imbere, intebe za PTFE, zikozwe neza kugira ngo zikore agapfundikizo gakomeye nk'ak'udupira. Ubwo buryo bwo gufunga ni bwo butuma amazi ava. Valve zihendutse zifite agapfundikizo gafunguye zizunguruka byoroshye, ariko kandi zirananirwa vuba. Tekereza nk'inkweto nshya z'uruhu; zigomba kuvunika. Uburyo bwiza bwo kubikora ni ugukoresha agapfundikizo gato gashobora guhindurwa ku gice kinini cy'umugozi w'umufata, aho hasi. Ibi biguha imbaraga nyinshi udashyize imbaraga ku mufata wa T ubwawo. Nyuma yo kuwufungura no kuwufunga inshuro nke, uzaba woroshye cyane.Ntukigere ukoresha WD-40 cyangwa andi mavuta akozwe mu mavuta.Ibi bikoresho bishobora kwibasira no gucika intege pulasitiki ya PVC na EPDM O-ring seals, bigatuma valve icika intege uko igihe kigenda.

Umwanzuro

Gushyiramo neza, hakoreshejwe uburyo bukwiye bwo guhuza, icyerekezo, no gushyiramo kole, ni bwo buryo bwonyine bwo kwemeza koValve y'umupira ya PVCitanga serivisi ndende, yizewe kandi idatemba amazi.
