Nigute ushobora guhitamo ikinyugunyugu gikwiye?

Ikinyugunyugu cya plastiki ni igikoresho gisanzwe kigenzura amazi, gikoreshwa cyane mu nganda, mu bwubatsi no mu buhinzi. Hano hari UPVC CPVC PPH PVDF PPH ibikoresho byikinyugunyugu. Ingano yikinyugunyugu ya lever irimo DN50, DN65 DN80, DN100, DN 200, Inzoka zikoresha ibinyugunyugu zirimo DN50 ~ DN300. Ifite ibyiza byuburyo bworoshye, imikorere yoroshye no kurwanya ruswa, bityo itoneshwa cyane nabakoresha. Ariko, mugihe tugura ibinyugunyugu bya plastike, dukeneye gusuzuma ibintu bimwe byingenzi. Iyi ngingo izaguha icyerekezo cyo guhitamo ibinyugunyugu bya plastike kugirango bigufashe guhitamo ibicuruzwa byiza.

1, Guhuza imiti:

Menya imiti yihariye cyangwa amazi ya valve izahura nayo. Hitamo ibikoresho bya pulasitike kumubiri wa valve nibigize birwanya cyane ingaruka mbi zangiza imiti. Plastiki zitandukanye zifite urwego rutandukanye rwo kurwanya imiti itandukanye, bityo guhuza ibikoresho nibintu byihariye bya shimi ni ngombwa.

2, Hitamo ibikoresho byiza:

Ibinyugunyugu bya plastike bikozwe mubikoresho bitandukanye, bikunze kuboneka muri PVC (polyvinyl chloride), CPVC (chlorine polyvinyl chloride), PP (polypropylene), PVDF (polyvinylidene fluoride) na PTFE (polytetrafluoroethylene), nibindi bikoresho bitandukanye bifite. imikorere itandukanye, ugomba rero guhitamo ibikoresho bikwiye ukurikije ibikenewe byihariye. Muri rusange, polypropilene ikwiranye nuburyo rusange, PVC ikwiranye na acide nkeya na alkali, PTFE ikwiranye na acide ikomeye na alkali, naho FRP ikwiranye nubushyuhe bwo hejuru.

muguhitamo PVC, CPVC, PP cyangwa PVDF ikinyugunyugu kubikoresha bitandukanye, ni ngombwa gusuzuma imiterere ya chimique ya buri kintu. Ibikurikira nubuyobozi rusange bwo guhuza ibyo bikoresho nimiti itandukanye:

PVC (polyvinyl chloride) ikinyugunyugu:

Birakwiye kuvura amazi, aside (dilute), alkali numuti wumunyu.

Ntabwo bisabwa gukoreshwa hamwe na acide ikomeye, ketone, esters hamwe na hydrocarbone ya aromatic cyangwa chlorine.

CPVC (chlorine polyvinyl chloride) ikinyugunyugu:

Kurwanya imiti yagutse kuruta PVC, harimo amazi ashyushye yangiza, umunyu, na acide nyinshi na alkalis.

Ntabwo bisabwa gukoreshwa hamwe na solide, hydrocarbone ya aromatic na hydrocarbone ya chlorine.

PP (polypropilene) ikinyugunyugu:

Kurwanya acide zitandukanye, alkalis hamwe na solge organic.

Ntabwo bisabwa gukoreshwa hamwe na acide ikomeye ya okiside, hydrocarbone ya chlorine, hydrocarbone ya aromatic na halogene.

PVDF (fluoride polyvinylidene) ikinyugunyugu:

Kurwanya cyane imiti myinshi yangirika, harimo acide ikomeye, ibishingwe hamwe na sologene ya halogene.

Birakwiye mugukoresha imiti yangirika hamwe nubushakashatsi buhanitse.

Wemeze kubaza imbonerahamwe ihuza imiti nurupapuro rwihariye rwibikoresho kugirango umenye neza guhitamo neza ibinyugunyugu bya PVC, CPVC, PP cyangwa PVDF kubikoresha bitandukanye. Byongeye kandi, tekereza ubushyuhe nigitutu kimwe nubuziranenge ninganda mugihe uhitamo.

3. Witondere imiterere yumubiri wa valve:

Imiterere ya plastike ikinyugunyugu ya valve nayo ni kimwe mubintu bigomba kwitabwaho mugihe uguze. Imiterere ya valve yumubiri isanzwe ifite ubwoko bwa flange, ubwoko bwurudodo nubwoko bwo gusudira. Umubiri wa flanged umubiri ukwiranye na diameter nini nigihe cyumuvuduko mwinshi, umubiri wumugozi wa valve ukwiranye na diameter ntoya nigihe cyumuvuduko muke, umubiri wa valve wasudutse ubereye ubushyuhe bwinshi nigihe cyumuvuduko mwinshi. Kubwibyo, ugomba guhitamo imiterere yumubiri wa valve ukurikije uko ibintu bimeze mugihe ugura.

4. Witondere ibikoresho byicaro:

Intebe ya valve nigice cyingenzi cyikinyugunyugu cya plastike, bigira ingaruka itaziguye kumikorere ya kashe. Ibikoresho bisanzwe byicaraho birimo EPDM (Ethylene propylene diene monomer), Buna-N (rubber nitrile), fluoroelastomer (FKM 、 FPM 、 VITON), PTFE na polyurethane. FKM 、 FPM 、 VITON ifite ruswa nziza kandi irwanya ruswa, PTFE ifite ruswa nziza kandi irwanya ubushyuhe bwinshi, kandi polyurethane ifite abrasion nziza kandi irwanya amavuta. .

Ibi bikoresho byatoranijwe kubushobozi bwabo bwo gutanga kashe ikomeye, kwambara, no guhuza ibintu bitandukanye byamazi nubushyuhe. Ibikoresho byihariye bikoreshwa mu myanya ya kinyugunyugu ya plastike biterwa na porogaramu, ubwoko bwamazi agenzurwa, nuburyo imikorere ikora.

Mugihe ugura, ugomba guhitamo ibikoresho byabigenewe bya valve ukurikije ibiranga uburyo

00001.

5, Umuvuduko nubushyuhe:

Hitamo indangagaciro zishobora gukemura ibibazo byubushyuhe nubushyuhe muri sisitemu kugirango ukore neza kandi wizewe.

Izina ryibikoresho bya plastiki nubushyuhe bukoreshwa:

6, Ingano n'inzira:

Hitamo ingano ya valve nigitemba gihuye nibisabwa na sisitemu kugirango ugere kubyo wifuza kugenzura.

7. Reba uburyo bwo gukora:

Ibinyugunyugu bya plastiki bikoreshwa mu ntoki, amashanyarazi na pneumatike. Igikorwa cyintoki kiroroshye, igiciro gito, kibereye sisitemu nto; gukora amashanyarazi biroroshye, byukuri, bikwiranye na sisitemu nini; imikorere ya pneumatike irihuta, murwego rwohejuru rwo kwikora, ikwiranye na sisitemu isaba guhinduranya kenshi. Kubwibyo, mugugura ibikenewe guhitamo uburyo bukwiye bwo gukora ukurikije ibikenewe nyirizina.

8. Witondere ibipimo bya valve no gutanga ibyemezo:

Mu kugura ibinyugunyugu bya plastike, ugomba kandi kwitondera niba valve yujuje ibipimo bijyanye nibisabwa. Ibipimo rusange nibyemezo ni ISO, CE, API nibindi. Guhitamo ibicuruzwa byujuje ubuziranenge nibisabwa byemeza birashobora kwemeza ubwiza n'umutekano byibicuruzwa.

Urebye neza ibi bintu, urashobora guhitamo ikinyugunyugu cya plastike ikwiranye nogukoresha imiti itandukanye, ukarinda umutekano, kwiringirwa no kuramba mubisabwa.
