Binyuze mu kumenyekanisha ibintu fatizo bisabwa, ibisabwa mu gishushanyo, ibisabwa mu nganda, ibisabwa mu mikorere, uburyo bwo gukora ibizamini, ibisabwa muri sisitemu, hamwe n’isano iri hagati y’umuvuduko nubushyuhe mu bicuruzwa mpuzamahanga bya valve ya plastike hamwe nuburyo bwo gupima, urashobora kumva kashe isabwa kuri plastiki valve Ibyingenzi byingenzi bigenzurwa nkibizamini, ikizamini cya torque hamwe nimbaraga zipima umunaniro. Muburyo bwimbonerahamwe, ibisabwa kugirango ikizamini cyo gufunga intebe, ikizamini cyo gufunga umubiri wa valve, ikizamini cyingufu zumubiri, ikizamini cyigihe kirekire, ikizamini cyingufu zumunaniro hamwe numuriro wumuriro ukenewe kubisabwa kugirango ibicuruzwa bya plastike bishoboke. Binyuze mu biganiro byibibazo byinshi mubipimo mpuzamahanga, ababikora nabakoresha ibikoresho bya plastike bitera impungenge.

Mugihe igipimo cyimiyoboro ya pulasitike mugutanga amazi ashyushye nubukonje hamwe nogukoresha inganda zikora inganda zikomeje kwiyongera, kugenzura ubuziranenge bwibikoresho bya pulasitike muri sisitemu yo kuvoma plastike biragenda biba ngombwa.

Bitewe nibyiza byuburemere bworoshye, kurwanya ruswa, kutamenyekanisha igipimo, guhuza imiyoboro ya pulasitike, hamwe nubuzima burebure bwimyanda ya plastike, indangagaciro za plastike zikoreshwa mugutanga amazi (cyane cyane amazi ashyushye nubushyuhe) nandi mazi yinganda. Muri sisitemu yo kuvoma, inyungu zayo zo kuyikoresha ntagereranywa nizindi valve. Kugeza ubu, mu gukora no gushyira mu bikorwa indangagaciro za pulasitiki zo mu ngo, nta buryo bwizewe bwo kubigenzura, bigatuma habaho uburinganire buke bw’imyanda ya pulasitike yo gutanga amazi n’andi mazi yo mu nganda, bigatuma habaho gufunga no kumeneka gukabije mu bikorwa by’ubuhanga. Yakoze itangazo rivuga ko ububiko bwa pulasitike budashobora gukoreshwa, bigira ingaruka ku iterambere rusange ryimyanda ikoreshwa. Igipimo cy’igihugu cyanjye ku bipimo bya pulasitike biri mu nzira yo gutegurwa, kandi ibipimo by’ibicuruzwa n’ubuziranenge byakozwe hakurikijwe amahame mpuzamahanga.

Ku rwego mpuzamahanga, ubwoko bwa plaque ya plastike burimo cyane cyane imipira yumupira, ikinyugunyugu, kugenzura indangagaciro, diaphragm na valve yisi. Imiterere nyamukuru yuburyo ni inzira ebyiri, inzira-eshatu ninzira nyinshi. Ibikoresho fatizo ni ABS,PVC-U, PVC-C, PB, PE,PPna PVDF n'ibindi

Mubipimo mpuzamahanga byibicuruzwa bya plastike ya plastike, icyifuzo cya mbere ni ibikoresho fatizo bikoreshwa mugukora ibicuruzwa. Uwakoze ibikoresho fatizo agomba kuba afite umurongo wo kunanirwa wujuje ubuziranenge bwibicuruzwa bya pulasitiki. Muri icyo gihe, ikizamini cya kashe, ikizamini cyumubiri wa valve, hamwe muri rusange Ikizamini cyigihe kirekire, ikizamini cyingufu zumunaniro hamwe numuriro wumuriro wa valve byose byateganijwe, hamwe nubuzima bwa serivisi yubushakashatsi bwa valve ya plastike ikoreshwa mugutwara inganda za fluid zitangwa kuba imyaka 25.

Ibisabwa byingenzi bya tekiniki yubuziranenge mpuzamahanga

1 Ibikoresho bikenewe

Ibikoresho byumubiri wa valve, bonnet na bonnet bigomba gutoranywa hakurikijwe ISO 15493: 2003 “Sisitemu yo gutunganya inganda za plastike-ABS,PVC-Una PVC-C-Umuyoboro hamwe na sisitemu iboneye-Igice cya 1: Ibipimo by'ibipimo ”na ISO 15494: 2003“ Sisitemu yo gutunganya inganda za plastiki-PB, PE, na PP - Ibisobanuro bya Sisitemu na Fitingi - Igice cya 1: Urukurikirane rw'ibipimo. ”

2 Ibisabwa

a) Niba valve ifite icyerekezo kimwe gusa cyerekana icyerekezo, igomba gushyirwaho umwambi hanze yumubiri wa valve. Umuyoboro ufite igishushanyo mbonera ugomba kuba ukwiranye nuburyo bubiri bwo gutembera no kwigunga.

b) Igice cyo gufunga kiyobowe nigiti cya valve kugirango gifungure kandi gifunge valve. Igomba guhagarikwa kumpera cyangwa umwanya uwariwo wose hagati yo guterana amagambo cyangwa gukora, kandi umuvuduko wamazi ntushobora guhindura umwanya wacyo.

c) Ukurikije EN736-3, byibuze unyuze mu mwobo wa cavite igomba kuba yujuje ingingo ebyiri zikurikira:

- Kuri aperture iyo ari yo yose inyuzamo hagati ya valve, ntigomba kuba munsi ya 90% ya DN agaciro ka valve;

- Kuri valve ifite imiterere ikeneye kugabanya diameter yikigereranyo inyuramo, uyikora agomba kwerekana byibuze nyabyo binyuze mu mwobo.

d) Ikidodo kiri hagati yikibaho na valve umubiri ugomba kubahiriza EN736-3.

e) Kubijyanye no kwihanganira kwambara kwa valve, igishushanyo cya valve kigomba gusuzuma ubuzima bwa serivisi bwibice byambarwa, cyangwa uwabikoze agomba kwerekana mumabwiriza yimikorere icyifuzo cyo gusimbuza valve yose.

f) Igipimo gikoreshwa cyibikoresho byose bikora valve bigomba kugera kuri 3m / s.

g) Urebye uhereye hejuru ya valve, ikiganza cyangwa intoki za valve bigomba gufunga valve muburyo bwisaha.

3 Ibisabwa mu nganda

a) Imiterere yibikoresho byaguzwe bigomba kuba bihuye namabwiriza yabakozwe kandi byujuje ibisabwa nibicuruzwa.

b) Umubiri wa valve ugomba gushyirwaho kode yibikoresho fatizo, diameter DN, numuvuduko wizina PN.

c) Umubiri wa valve ugomba gushyirwaho izina ryuwabikoze cyangwa ikirango.

d) Umubiri wa valve ugomba gushyirwaho itariki yo gukora cyangwa code.

e) Umubiri wa valve ugomba gushyirwaho kode yahantu hatandukanye hakorerwa ibicuruzwa.

4 Ibisabwa mu gihe gito

Imikorere yigihe gito nikintu cyo kugenzura uruganda mubicuruzwa bisanzwe. Ikoreshwa cyane cyane mugupima kashe yintebe ya valve hamwe nikizamini cyo gufunga umubiri wa valve. Byakoreshejwe mukugenzura imikorere ya kashe ya plastike. Birasabwa ko valve ya plastike itagomba kugira imbere yimbere (valve intebe yamenetse). , Ntabwo hagomba kubaho gusohoka hanze (valve umubiri kumeneka).

Ikizamini cyo gufunga intebe ya valve ni ukugenzura imikorere ya sisitemu yo gutandukanya imiyoboro ya valve; Ikizamini cyo gufunga umubiri wa valve ni ukugenzura niba kashe ya kashe ya kashe ya kashe hamwe na kashe ya buri murongo uhuza impera.

Inzira zo guhuza plastike ya plastike na sisitemu y'imiyoboro ni

Guhuza gusudira kubuto: diameter yinyuma yikigice cyo guhuza ibice bingana na diametre yinyuma yumuyoboro, kandi isura yanyuma yikigice cyo guhuza ibice bihabanye nisura yanyuma yumuyoboro wo gusudira;

Guhuza sock ihuza: igice cyo guhuza valve kiri muburyo bwa sock, ihujwe numuyoboro;

Guhuza amashanyarazi ya electrofusion: igice cyo guhuza valve kiri muburyo bwa sock hamwe ninsinga zishyushya amashanyarazi zashyizwe kumurambararo wimbere, kandi ni umuyoboro wa electrofusion numuyoboro;

Sock ishyushye-gushonga ihuza: igice cyo guhuza valve kiri muburyo bwa sock, kandi ihujwe numuyoboro na hot-melt sock;

Guhuza sock ihuza: Igice cyo guhuza valve kiri muburyo bwa sock, ihujwe kandi ifatanye numuyoboro;

Isanduku ya reberi ifunga impeta: Igice cyo guhuza valve nubwoko bwa sock hamwe nimpeta yimbere yimbere, ifatanye kandi ihujwe numuyoboro;

Ihuza rya Flange: Igice cyo guhuza valve kiri muburyo bwa flange, ihujwe na flange kumuyoboro;

Guhuza insanganyamatsiko: igice cyo guhuza valve kiri muburyo bwurudodo, ruhujwe numurongo uri kumuyoboro cyangwa bikwiye;

Ihuza rya Live: Igice cyo guhuza ibice kiri muburyo bwo guhuza bizima, bihujwe n'imiyoboro cyangwa ibikoresho.

A valve irashobora kugira uburyo butandukanye bwo guhuza icyarimwe.

Isano iri hagati yumuvuduko wubushyuhe nubushyuhe

Mugihe ikoreshwa ryubushyuhe ryiyongera, ubuzima bwa serivisi ya plaque ya plastike buzagabanuka. Kugirango ukomeze ubuzima bwa serivisi imwe, birakenewe kugabanya umuvuduko ukoreshwa.
