Binyuze mu gushyira mu bikorwa ibisabwa mu bikoresho fatizo, ibisabwa mu gishushanyo, ibisabwa mu nganda, ibisabwa mu mikorere, uburyo bwo gupima, ibisabwa mu ikoreshwa rya sisitemu, hamwe n'isano iri hagati y'umuvuduko n'ubushyuhe mu bicuruzwa mpuzamahanga bya pulasitiki n'amahame ngenderwaho y'uburyo bwo gupima, urashobora gusobanukirwa uburyo bwo gufunga busabwa kuri pulasitiki Ibisabwa by'ibanze mu kugenzura ubuziranenge nk'ikizamini, ikizamini cya torque n'ikizamini cy'imbaraga z'umunaniro. Mu buryo bw'imbonerahamwe, ibisabwa mu ikizamini cyo gufunga icyicaro, ikizamini cyo gufunga umubiri wa pulasitiki, ikizamini cy'imbaraga z'umubiri wa pulasitiki, ikizamini cy'igihe kirekire cya valve, ikizamini cy'imbaraga z'umunaniro n'imbaraga z'imikorere zisabwa mu bijyanye n'imikorere y'ibicuruzwa bya pulasitiki. Binyuze mu kiganiro ku bibazo byinshi mu mahame mpuzamahanga, abakora n'abakoresha pulasitiki batera impungenge.

Uko igipimo cy'imiyoboro ya pulasitiki mu miyoboro y'amazi ashyushye n'akonje ndetse no mu miyoboro y'inganda gikomeza kwiyongera, ni ko kugenzura ubuziranenge bw'udupira twa pulasitiki mu miyoboro ya pulasitiki bigenda birushaho kuba ingenzi.

Bitewe n'ibyiza byoroshye, kurwanya ingese, kudafata igipimo, guhuza imiyoboro ya pulasitiki, no kumara igihe kirekire ikoreshwa rya plastike, plastike zikoreshwa mu gutanga amazi (cyane cyane amazi ashyushye n'ubushyuhe) n'andi mazi yo mu nganda. Mu buryo bwo kuyikoresha, inyungu zayo ntizigereranywa n'izindi plastike. Kuri ubu, mu gukora no gukoresha plastike zo mu ngo, nta buryo bwizewe bwo kuzigenzura, bigatuma habaho ubuziranenge butaringaniye bw'ibicuruzwa bya plastike ku mazi n'andi mazi yo mu nganda, bigatuma habaho gufunga no gutakaza amazi menshi mu bikorwa by'ubuhanga. Yashyizeho igitekerezo cy'uko plastike zidashobora gukoreshwa, bigira ingaruka ku iterambere rusange ry'imiyoboro ya plastike. Amahame ngenderwaho y'igihugu cy'igihugu ku plastike zirimo gutegurwa, kandi amahame ngenderwaho y'ibicuruzwa byabo n'amabwiriza y'uburyo byashyizweho hakurikijwe amahame mpuzamahanga.

Ku rwego mpuzamahanga, ubwoko bw'udupira twa pulasitiki burimo cyane cyane uturindantoki tw'umupira, uturindantoki tw'ibinyugunyugu, uturindantoki two kugenzura, uturindantoki tw'inyuma, n'uturindantoki tw'isi. Imiterere y'imiterere y'uturindantoki irimo uturindantoki tw'inzira ebyiri, uturindantoki dutatu n'uturindantoki twinshi. Ibikoresho by'ibanze ni ABS,PVC-U, PVC-C, PB, PE,PPna PVDF n'ibindi.

Mu bipimo mpuzamahanga by’ibicuruzwa bya pulasitiki, icya mbere gisabwa ni ibikoresho fatizo bikoreshwa mu gukora ibyuma. Ukora ibikoresho fatizo agomba kuba afite umurongo uhuza imiterere y’ibicuruzwa bya pulasitiki. Muri icyo gihe, ikizamini cyo gufunga, ikizamini cy’umubiri wa pulasitiki, na rusange Ikizamini cy’imikorere y’igihe kirekire, ikizamini cy’imbaraga z’umunaniro n’imbaraga z’imikorere ya mashini byose byagenwe, kandi igihe cyo gukora igishushanyo mbonera cya mashini ya pulasitiki ikoreshwa mu gutwara amazi mu nganda gihabwa imyaka 25.

Ibisabwa by'ingenzi mu bya tekiniki ku bipimo mpuzamahanga

1 Ibisabwa ku bikoresho fatizo

Ibikoresho by'umubiri wa valve, bonnet na bonnet bigomba gutoranywa hakurikijwe ISO 15493: 2003 “Sisitemu z'imiyoboro ya pulasitiki y'inganda-ABS, PVC-U na PVC-C-Ibisobanuro bya sisitemu yo kuyishyiramo-Igice cya 1: Metric series” na ISO 15494: 2003 “Sisitemu z'imiyoboro ya pulasitiki y'inganda-PB, PE, naPP—Umuyoboro n'ibikoresho byo kuwushyiramoIbisobanuro bya sisitemu—Igice cya 1: Urutonde rw'ibipimo.”

2 Ibisabwa mu gishushanyo mbonera

a) Niba valve ifite icyerekezo kimwe gusa gipima umuvuduko, igomba gushyirwaho akamenyetso inyuma y'umubiri wa valve. Valve ifite imiterere ingana igomba kuba ikwiriye gutembera kw'amazi mu nzira ebyiri no kuyatandukanya.

b) Igice cyo gufunga gitwarwa n'inkingi ya valve kugira ngo gifungure kandi gifunge valve. Gikwiye gushyirwa ku mpera cyangwa ahandi hantu hose hagati hakoreshejwe friction cyangwa actuators, kandi umuvuduko w'amazi ntushobora guhindura aho uherereye.

c) Dukurikije EN736-3, umwobo muto wo mu mwobo wa valve ugomba kuzuza ingingo ebyiri zikurikira:

— Ku mwobo uwo ari wo wose aho icyuma gica kuri vali, ntugomba kuba munsi ya 90% by'agaciro ka DN k'vali;

— Ku mvange ifite imiterere igomba kugabanya umurambararo w'ubuso bunyuramo, uwayikoze agomba kugaragaza nibura umwobo wayo.

d) Ifunze hagati y'umugongo wa valve n'umubiri wa valve rigomba kubahiriza EN736-3.

e) Ku bijyanye no kudashira kw'imvange, imiterere y'imvange igomba kuzirikana igihe cy'imikorere y'ibice byashaje, cyangwa uwakoze imvange agomba kwerekana mu mabwiriza y'imikorere inama yo gusimbuza imvange yose.

f) Igipimo cy'amazi gikwiye ku bikoresho byose bikoresha valve kigomba kugera kuri 3m/s.

g) Birebewe hejuru ya valve, umugozi cyangwa urunigi rw'intoki rwa valve bigomba gufunga valve mu cyerekezo cy'isaha.

3 Ibisabwa mu nganda

a) Imiterere y'ibikoresho fatizo byaguzwe igomba kuba ijyanye n'amabwiriza y'uwabikoze kandi ikujuje ibisabwa ku gicuruzwa.

b) Igice cy'agace k'umuyoboro kigomba gushyirwaho kode y'ibikoresho fatizo, umurambararo wa DN, n'umuvuduko wa PN.

c) Igice cy'umuyoboro w'amashanyarazi kigomba gushyirwaho izina ry'uwagikoze cyangwa ikirango cy'ubucuruzi.

d) Igice cy'umuyoboro w'amashanyarazi kigomba gushyirwaho itariki cyangwa kode y'uko cyakozwe.

e) Igice cy'umuyoboro w'amashanyarazi kigomba gushyirwaho kode z'aho ibikorwa bitandukanye by'uruganda rukora.

4 Ibisabwa mu gihe gito cyo gukora neza

Imikorere y'igihe gito ni ikintu gikorerwa mu ruganda mu buryo busanzwe. Gikoreshwa cyane cyane mu isuzuma ryo gufunga intebe ya valve no mu isuzuma ryo gufunga umubiri wa valve. Gikoreshwa mu kugenzura imikorere yo gufunga umupira wa pulasitiki. Ni ngombwa ko valve ya pulasitiki itagira imyanda imbere (imyanda y'intebe ya valve). , Nta myanda ikwiye kubaho hanze (imyanda y'umubiri wa valve).

Ikizamini cyo gufunga icyicaro cya valve ni ukugenzura imikorere y'imiyoboro ya valve isolation; ikizamini cyo gufunga icyicaro cya valve ni ukugenzura niba ifunga ry'agace k ...

Uburyo bwo guhuza valve ya pulasitiki n'imiyoboro ni

Guhuza imiyoboro yo gusudira: umurambararo w'inyuma w'igice gihuza imiyoboro ungana n'umurambararo w'inyuma w'umuyoboro, kandi isura y'inyuma y'igice gihuza imiyoboro yo gusudira iri mu ruhande rw'inyuma rw'umuyoboro wo gusudira;

Guhuza soketi: igice gihuza valve kiri mu ishusho y'isoketi, ifatanye n'umuyoboro;

Guhuza soketi ya Electrofusion: igice gihuza valve kiri mu ishusho y'isoketi ifite insinga y'amashanyarazi ishyushya ishyizwe ku murambararo w'imbere, kandi ni uguhuza electrofusion n'umuyoboro;

Guhuza Socket hot-melt: igice gihuza valve kiri mu ishusho y'isoko, kandi gihuzwa n'umuyoboro hakoreshejwe soko ishyushye-melt;

Guhuza soketi: Igice gihuza valve kiri mu ishusho y'isoketi, ifatanye kandi igashyirwamo umuyoboro;

Ihuza impeta yo gufunga irangi: Igice cyo guhuza valve ni ubwoko bw'ihuza ifite impeta yo gufunga irangi imbere, ifatanye n'umuyoboro;

Guhuza flange: Igice cyo guhuza valve kiri mu ishusho ya flange, ihujwe n'flange iri ku muyoboro;

Uguhuza insinga: igice gihuza valve kiri mu ishusho y'insinga, ihujwe n'insinga iri ku muyoboro cyangwa ku gikoresho gifata;

Guhuza imbonankubone: Igice cyo guhuza valve kiri mu buryo bwo guhuza imbonankubone, gihujwe n'imiyoboro cyangwa ibikoresho.

Valve ishobora kugira uburyo butandukanye bwo guhuza icyarimwe.

Isano iri hagati y'umuvuduko w'imikorere n'ubushyuhe

Uko ubushyuhe bugenda bwiyongera, ubuzima bwo gukoresha valve za pulasitiki buzagabanuka. Kugira ngo ubuzima bwo gukoresha bukomeze kuba bumwe, ni ngombwa kugabanya umuvuduko wo gukoresha.
