Ugomba kugenzura amazi atembera, ariko reba ubwoko bwinshi bw'amavali. Guhitamo iryariryo ritari ryo bishobora gutera amazi kuva, kuziba, cyangwa kunanirwa kugenzura sisitemu yawe neza, bigatera kwangirika gukomeye.

Hari ubwoko bwinshi bwa valve za PVC, ariko izikunze kugaragara cyane nivalve z'umupiraku buryo bwo kugenzura buri gihe,valve zo kugenzurakugira ngo hirindwe ko habaho gusubira inyuma kw'amazi, novalve zo mu irembokugira ngo habeho kwitandukanya byoroshye. Buri bwoko bukora akazi gatandukanye cyane mu buryo bw'amazi.

Gusobanukirwa imikorere y'ibanze ya buri vali ni ingenzi cyane. Nkunda gukoresha ikigereranyo cyoroshye iyo mvugana n'abafatanyabikorwa nka Budi muri Indoneziya. Vali y'umupira ni nk'urufunguzo rw'amatara—irazima cyangwa irazimye, vuba. Vali y'irembo imeze nk'uruzitiro rugenda buhoro kandi rwitondewe. Kandi vali y'igenzura ni nk'urugi rw'icyerekezo kimwe rutuma abantu binjira mu cyerekezo kimwe gusa. Abakiriya be—ba rwiyemezamirimo, abahinzi, abashyiramo pisine—basanga ibi byoroshye cyane guhitamo ibicuruzwa bikwiye. Iyo umaze kumenya akazi vali igomba gukora, amahitamo arasobanutse.

Ese valve zose za PVC ni zimwe?

Ubona valve ebyiri za PVC zisa, ariko imwe igura kabiri. Biragoye kugura ihendutse, ariko uhangayikishijwe nuko izapfa igateza akaga.

Oya, valve zose za PVC ntabwo ari zimwe. Zitandukanye cyane mu bwiza bw'ibikoresho, ibikoresho bifunga, imiterere, n'uburyo bikozwe neza. Izi tandukaniro zigira ingaruka ku buryo butaziguye ku gihe valve imara n'uburyo ikora neza iyo irimo igitutu.

Itandukaniro riri hagati y'ingufu nziza n'ingufu riri mu buryo burambuye udashobora kubona buri gihe. Icya mbere niIbikoresho bya PVCubwayo. Twe muri Pntek dukoresha PVC 100% idahinduka, ikomeye, iramba, kandi ifite irangi ryiza cyane. Amavali ahendutse akunze gukoresha PVC yasubiwemo ivanze n'amavali nkakarubone ya kalisiyumuIbi bituma valve iremereye, ariko nanone irushaho kugorama no gucikagurika. Ibikurikira ni ibi bikurikira:ibirangoImpeta z'umweru ziri imbere zifunga umupira zitwa intebe. Alava nziza zikoresha isukuPTFE (Teflon)kugira ngo ipfundikishe neza, idacikagurika cyane kandi iramba. Izihendutse zikoresha pulasitiki yo mu rwego rwo hasi kandi zishaje vuba. Impeta z'umukara za O-rings ku giti zigomba kuba ari EPDM, ikaba ari nziza cyane mu kurwanya amazi n'imiraba ya UV, ntabwo ari rubber ya NBR ihendutse. Amaherezo, ni ukurebaubuziranenge.Uruganda rwacu rwikora rutuma buri vali izenguruka neza. Vali zakozwe nabi zishobora gukomera kandi zikagorana kuzizunguza, cyangwa zigacika intege ku buryo zumva ko zitari izizerwa.

Ni ikihe cyiza kurusha ibindi, ivalu ya PVC cyangwa iy'icyuma?

Icyuma gisa n'ikiremereye kandi gikomeye, mu gihe PVC isa n'aho yoroheje. Imitekerereze yawe ivuga ko icyuma ari cyo cyiza buri gihe, ariko icyo gitekerezo gishobora gutuma sisitemu inanirwa kwangirika.

Nta na kimwe muri byo cyiza kurushaho; byubatswe ku mirimo itandukanye. PVC ni nziza ku mazi akonje n'ahantu hangiza aho ibyuma bishobora kwangirika cyangwa bigafata ingese. Icyuma ni ngombwa ku bushyuhe bwinshi, umuvuduko mwinshi, n'ibindi bintu bimwe na bimwe bya shimi.

Guhitamo hagati ya PVC n'icyuma ntabwo ari imbaraga, ahubwo ni ubutabire. Akamaro kanini ka PVC ni uko ariidakingiwe ingese n'uburozi. Budi afite umukiriya mu nganda z’ubworozi bw’amafi wahoraga asimbuza imigozi ye y’umuringa buri mwaka kubera ko amazi y’umunyu yatumaga ayifata. Kuva yahindura imigozi yacu ya PVC, nta kibazo amaze imyaka itanu agira. Ikora neza nk’umunsi wa mbere. Aha niho PVC ari yo itsindira: kuhira ifumbire, pisine, imigozi y’amazi y’umunyu, n’amazi rusange. Ariko, PVC ifite aho igarukira. Ntishobora gukoreshwa mu mazi ashyushye, kuko yoroha kandi ikananirwa. Ifite kandi igipimo gito cy’umuvuduko ugereranije n’icyuma. Umugozi w’icyuma (nk’icyuma cyangwa umuringa) ni wo wonyine ukoreshwa mu migozi y’umwuka, mu buryo bw’amazi ashyushye, cyangwa mu nganda zikoresha umuvuduko mwinshi. Icy’ingenzi ni uguhuza ibikoresho bya valvu n’amazi anyuramo.

PVC vs. Icyuma: Ni ikihe wahitamo?

Ni iki gituma valve ya PVC iba 'nziza'?

Urimo guhaha kuri interineti ugasanga valve ya PVC ku giciro gito cyane. Uratekereza niba ari uguze neza cyangwa niba ugiye kugura ikibazo kizava mu gihe kizaza saa mbiri za mu gitondo.

Valve ya PVC "nziza" ikozwe muri PVC idapfa kwibagirana 100%, ikoresha intebe za PTFE zo mu rwego rwo hejuru n'impeta za EPDM O, izunguruka neza, kandi yageragejwe igitutu mu ruganda kugira ngo irebe ko nta mazi asohoka.

Hari ibintu bike mbwira itsinda rya Budi ngo rishake. Ubwa mbere, banza urebeumubiri. Igomba kuba ifite irangi ryoroshye, ribengerana gato. Isura idasobanutse neza kandi isa n'iy'ishwagara akenshi igaragaza ikoreshwa ry'ibikoresho byo kuzura, bigatuma icika intege. Icya kabiri,koresha umukingo. Igomba kuzunguruka neza kandi ihamye kuva ifunguye kugeza ifunze neza. Iyo ikomeye cyane, ihindagurika, cyangwa ikumva irimo ubushyuhe, imbere iba mbi. Ibi bituma habaho amazi n'umukingo ushobora gucika. Icya gatatu, shakishaibimenyetso bisobanutse neza. Valve nziza izaba ifite ikimenyetso gisobanutse neza cy'ingano yayo, igipimo cy'umuvuduko (nka PN10 cyangwa PN16), n'ubwoko bw'ibikoresho (PVC-U). Inganda zizwi zishimira imiterere yazo. Amaherezo, ni icyizere. Muri Pntek, valve yose dukora igeragezwa mbere yuko iva mu ruganda. Ibi byemeza ko itazava. Icyo ni cyo kintu kitagaragara wishyura: amahoro yo mu mutima ko izakora gusa.

Ese valve nshya ya PVC ifite icyo ihindura?

Ufite valve ishaje ikomeye ku buryo idashobora guhindagurika cyangwa ifite amazi agabanuka buhoro cyane. Bisa nkaho ari ikibazo gito, ariko kubyirengagiza bishobora gutuma sisitemu yawe ishobora guhura n'ibibazo bikomeye.

Yego, valve nshya ya PVC iratanga itandukaniro rikomeye. Ihita yongera umutekano ikoresheje gusimbuza ibikoresho byoroshye, ikagira umupfundikizo mwiza wo guhagarika amazi, kandi igatanga imikorere myiza kandi yizewe igihe uyikeneye cyane.

Gusimbuza valve ishaje si ugusana gusa; ni ivugurura rikomeye mu bice bitatu by'ingenzi. Icya mbere niumutekano. Valve ya PVC imaze imyaka myinshi ku zuba iracika intege. Umukingo wayo ushobora gucika, cyangwa ikibi kurushaho, umubiri ushobora kwangirika bitewe n'impanuka nto, bigatera umwuzure mwinshi. Valve nshya igarura imbaraga z'umwimerere z'ibikoresho. Icya kabiri nikwizerwa. Gutonyanga buhoro buhoro kuva kuri vali ishaje si amazi yakoreshejwe gusa; bigaragaza ko ibifunga by'imbere byananiwe. Vali nshya ifite intebe nshya za PTFE n'impeta za EPDM O-rings bitanga uburyo bwo gufunga neza kandi bufunga neza ushobora kwiringira. Icya gatatu niubushobozi bwo gukoraMu gihe cy'impanuka, ugomba kuzimya amazi vuba. Valve ishaje ikomeye bitewe n'igihe cyangwa igipimo ntacyo imaze. Valve nshya irahinduka neza, ikaguha uburyo bwo kuyigenzura ako kanya. Ku giciro gito cyavalve, ugarura umutekano, ubwizerwe, n'imikorere y'ahantu hagenzurwa cyane muri sisitemu yawe.
