Ni bangahe uzi kuriindanga?

Iriburiro: binyuze mubipimo mpuzamahanga byibicuruzwa bya pulasitike hamwe nuburyo bwo gupima ibikenerwa byibanze, ibisabwa byubushakashatsi nibisabwa mu nganda, ibisabwa mu mikorere, uburyo bwikizamini, ibisabwa muri sisitemu no gukoresha igitutu nubushyuhe, nibindi, isano iri hagati irashobora kumva igikenewe ya plastike ya valve ikizamini, ikizamini cya torque hamwe numunaniro wimbaraga nibindi bisabwa byibanze byo kugenzura ubuziranenge. Ibisabwa bya kashe ya kashe yikizamini, ikizamini cyumubiri wa valve, ikizamini cyumubiri wimbaraga, ikizamini cyigihe kirekire, ikizamini cyimbaraga zumunaniro hamwe na torque ikora byegeranijwe muburyo bwameza. Binyuze mu biganiro byibibazo byinshi mubipimo mpuzamahanga, ababikora nabakoresha ibikoresho bya plastike bireba. Hamwe n’ubwiyongere bw’imiyoboro ya pulasitike mu gutanga amazi akonje kandi ashyushye hamwe n’inganda zikoreshwa mu nganda, kugenzura ubuziranenge bwa valve ya plastike muri sisitemu y’imiyoboro ya pulasitike biragenda biba ngombwa. Kuberako valve ya plastike ifite ibyiza byuburemere bworoshye, kurwanya ruswa, nta gipimo cya adsorption, hamwe no guhuza imiyoboro ya pulasitike hamwe nubuzima bwa serivisi ndende, valve ya plastike mugutanga amazi (cyane cyane amazi ashyushye nubushyuhe) no gukoresha inganda zindi mazi mumiyoboro ya plastike sisitemu, ibyiza byayo ni izindi valve ntishobora kugereranywa. Kugeza ubu mu musaruro w’imbere mu gihugu no gushyira mu bikorwa ububiko bwa pulasitike, kugenzura ntabwo ari inzira yizewe, gutanga amazi n’andi mashanyarazi ya pulasitike y’amazi akoreshwa mu bwiza bw’ibicuruzwa by’inganda ntago aringaniye, gukoresha inganda zikoreshwa mu gufunga ibintu no gufunga ibintu birakomeye, gukora plastike valve ntishobora gukoresha, bigira ingaruka kumajyambere rusange yo gukoresha imiyoboro ya plastike. Igipimo cyigihugu cya valve ya plastike mugihugu cyacu kiri mubikorwa byo gukora, igipimo cyibicuruzwa nuburyo bwuburyo bikozwe hakurikijwe amahame mpuzamahanga. Ubwoko bwa plastike mpuzamahanga ni cyane cyane umupira wumupira, ikinyugunyugu, kugenzura valve, diaphragm valve na globe yisi, imiterere yuburyo nyamukuru bwa valve ebyiri, eshatu ninzira nyabagendwa, ibikoresho nyamukuru ni ABS, PVC-U, PVC- C, PB, PE, PP na PVDF nibindi. Mubipimo mpuzamahanga byibicuruzwa bya plastike, mbere ya byose, ibikoresho fatizo bikoreshwa mugukora ibicuruzwa. Abakora ibikoresho bibisi bagomba kugira umurongo wo kunanirwa gukurikiza umurongo wibicuruzwa bya pulasitiki. Muri icyo gihe, ikizamini cyo gufunga kashe, ikizamini cyumubiri wa valve, ikizamini cyigihe kirekire, ikizamini cyimbaraga zumunaniro hamwe numuriro wumuriro wa valve yose iteganijwe, kandi ubuzima bwogushushanya ubuzima bwa valve ya plastike ikoreshwa mugutwara amazi yinganda ni imyaka 25. ISO 15 493 15493. igomba kuba ihuje na ISO 15493: 2003 Sisitemu yo kuvoma plastike yo gukoresha inganda - ABS, PVC-U na PVC-C - Imiyoboro ya sisitemu yo guhuza imiyoboro hamwe na ISO 15494: 2003 Sisitemu yo kuvoma plastike yo gukoresha inganda - PB, PE na PP - Imiyoboro n'ibikoresho bya sisitemu Ibisobanuro - *** Igice: Urukurikirane rw'ibipimo. A) Niba valve * ifite icyerekezo gifatika, igomba gushyirwaho umwambi hanze yumubiri wa valve. Indangagaciro zubushakashatsi zigomba kuba zibereye inzira ebyiri no kwigunga. B) Igice cyo gufunga kiyobowe nigiti cya valve kugirango gifungure kandi gifunge valve. Igomba guhagarikwa kumwanya wanyuma cyangwa umwanya uwo ariwo wose wo hagati ukoresheje guterana amagambo cyangwa gukora, kandi umuvuduko wamazi ntushobora guhindura umwanya wacyo. C) Dukurikije EN736-3, umuto muto unyuze mu mwobo uri mu cyuho cya valve ugomba guhuza n'ingingo ebyiri zikurikira: - kuri aperture iyo ari yo yose yo mu cyerekezo giciriritse, ntigomba kuba munsi ya 90% by'agaciro ka DN; Kubyingenzi bisabwa muburyo bwo kugabanya umuvuduko ukabije, uwabikoze agomba kwerekana byibuze nyabyo binyuze mu mwobo. D) Ikidodo hagati yumuti numubiri bigomba gukurikiza EN736-3. E) Kubijyanye no kwangirika kwimyanda, igishushanyo mbonera kizirikana ubuzima bwa serivisi bwibice byambarwa, cyangwa uwabikoze agomba kwerekana mumabwiriza yimikorere ibyifuzo byo gusimbuza valve yose. F) ibikoresho byose bikora bya valve bigomba kugira umuvuduko wa 3m / s. G) Iyo urebye hejuru ya valve, ikiganza cya valve cyangwa intoki zigomba gufunga isaha yisaha. 3 Ibisabwa mu nganda a) Imikorere yibikoresho byaguzwe bigomba kuba bihuye nibisobanuro byakozwe nuwabikoze kandi byujuje ubuziranenge bwibicuruzwa. B) Ibikoresho fatizo, diameter DN hamwe nigitutu nominal PN bizashyirwaho ikimenyetso kumubiri wa valve. C) Umubiri wa valve ugomba gushyirwaho izina ryuwabikoze cyangwa ikirango. D) Umubiri wa valve ugomba gushyirwaho itariki yo gukora cyangwa nimero ya kode. E) Umubiri wa valve ugomba gushyirwaho kode yuwabikoze ahantu hatandukanye. Ibikorwa 4 byigihe gito bisabwa gukora mugihe gito mubikorwa byibicuruzwa nibintu byo kugenzura uruganda, cyane cyane gukora ikizamini cyo gufunga intebe ya valve hamwe nikizamini cyo gufunga umubiri, cyakoreshejwe mukugenzura imikorere yikimenyetso cya plastike, ububiko bwa plastike bushobora ntugire imbere yimbere (valve intebe yamenetse) phenomenon, ntishobora kandi kugira ibintu biva hanze (valve leakage). Ikizamini cya kashe ya valve ni ukugenzura imikorere ya sisitemu yo gutandukanya imiyoboro ya valve; Ikizamini cya kashe yumubiri ni ukugenzura niba kashe ya kashe ya kashe hamwe na kashe ihuriweho. Sisitemu ya pulasitike na sisitemu ihuza imiyoboro yo gusudira: umurambararo winyuma wigice cyo guhuza ibice bingana na diametre yinyuma yumuyoboro, kandi isura yanyuma yikigice cyahujwe irasudira ugereranije nisura yanyuma yumuyoboro; Guhuza sock ihuza: igice gihuza valve kiri muburyo bwa sock, ihujwe nibikoresho bya pipe; Umuyoboro w'amashanyarazi uhuza: igice cyo guhuza valve nuburyo bwa sock hamwe ninsinga zishyushya amashanyarazi mumurambararo wimbere, kandi bigahuzwa numuyoboro; Sock hot hot melt ihuza: igice cyo guhuza valve nuburyo bwa sock, kandi umuyoboro uhujwe na hoteri ishushe; Ihuza rya sock ihuza: igice cyo guhuza valve kiri muburyo bwa sock, kandi umuyoboro uhuza sock ihuza; Gufata reberi ifunga impeta: igice cyo guhuza valve nuburyo bwo kwifata impeta ya kashe ya kashe, kandi umuyoboro uhujwe na sock; Ihuza rya flange: igice cyo guhuza valve kiri muburyo bwa flange, ihujwe na flange kumuyoboro; Guhuza insanganyamatsiko: igice cyo guhuza valve kiri muburyo bwurudodo, gihujwe numutwe kumiyoboro cyangwa imiyoboro; Ihuza rizima: igice cyo guhuza valve kiri muburyo bwo guhuza bizima, kandi imiyoboro cyangwa imiyoboro ihuza. Amahuriro atandukanye arashobora gukorwa icyarimwe kumurongo umwe. Hamwe no kwiyongera kwubushyuhe, ubuzima bwa serivisi ya valve plastike bugomba kugabanywa. Kugirango ukomeze ubuzima bumwe bwa serivisi, ugomba kugabanya igitutu cya serivisi.
