Guhitamo valve ya pulasitiki itari yo bishobora gutuma sisitemu inanirwa bitewe n'ubushyuhe cyangwa imikorere ya shimi. Valve iva ishobora kwangiza cyane, gutinda k'umushinga, no kwangiza izina ryawe imbere y'abakiriya.

Ndibuka ikiganiro nagiranye na Budi ku mukiriya watangaga uruganda rushya rutunganya ibiribwa muri Indoneziya. Bavuze hafi ibyavuzwe mu mushinga wose uko bisanzwe.Vali za PVCkuzigama amafaranga. Twaganiriye vuba ku bijyanye no gusukura amazi ashyushye n'imiti yihariye bakoreshaga. Byaragaragaye ko PVC yari kuba yarananiwe mu mezi make. Dusobanura itandukaniro riri hagatiPVC, CPVC, na PP, twabafashije guhitamo ibikoresho bikwiye, tubarinda ikibazo gikomeye kandi gihenze. Ubwo bumenyi bwihariye ni bwo bwubaka icyizere kandi bugatuma umushinga ugira icyo ugeraho.

Ni iyihe PVC, UPVC, cyangwa CPVC nziza kurusha izindi?

Urabona PVC, UPVC, na CPVC byanditse ku mpapuro zigaragaza imiterere. Bisa, ariko ibiciro biratandukanye. Guhitamo nabi bishobora gusobanura ko uguze valve idakomeye cyangwa ihenze cyane ku kazi.

CPVC ni nziza ku mazi ashyushye kandi ifite ubushobozi bwo kurwanya imiti. Ku miyoboro na za valve, PVC na UPVC ni kimwe muri byo—ibikoresho bikomeye kandi bikomeye bikwiriye gukoreshwa mu mazi akonje.

Reka dusobanure neza ikintu gikunze kugaragara mu rujijo. Iyo tuvuze ku miyoboro na valves muri Pntek, "PVC" mu by'ukuri bisobanura "UPVC" (Polyvinyl Chloride idakozwe muri pulasitiki). Ni pulasitiki ikomeye kandi iramba ubona hose. Rero, ntugomba guhitamo hagati yazo; ni zimwe ku ntego zacu. Amahitamo nyayo ni hagati ya PVC na CPVC. "C" muri CPVC isobanura Chloride. Intambwe y'inyongera mu gukora yongera chlorine nyinshi ku miterere y'ibikoresho. Iri hinduka ryoroshye ni ryo riha CPVC ibyiza bibiri by'ingenzi: ishobora kwihanganira ubushyuhe bwinshi cyane, kandi ishobora kurwanya ubwoko bwinshi bw'imiti, cyane cyane aside na bases. Rero, niba akazi karimo amazi akonje gusa, PVC ni yo mahitamo meza cyane. Niba harimo ubushyuhe cyangwa imiti ikaze, CPVC ni yo mahitamo meza kandi yizewe.

Akamaro k'umupira wa CPVC ni akahe?

Umukiriya wawe akeneye valve yo gukoresha umuyoboro w'amazi ashyushye mu ruganda cyangwa mu rugo. Valve isanzwe ya PVC yera yakoroha, igahinduka, ikananirwa, bigatuma amazi ava nabi ndetse bigatuma sisitemu idakora neza.

Intego nyamukuru ya valve y'umupira wa CPVC ni ugufata amazi mu buryo bwizewe ku bushyuhe buri hejuru kurusha uko PVC isanzwe ishobora kwihanganira. Yagenewe by'umwihariko gukwirakwiza amazi ashyushye no kwangiza imiyoboro y'amazi yo mu nganda.

Tekereza kuri CPVC nk'uburyo bworoshye bwa PVC. Akazi kayo k'ibanze ni ugukora aho PVC idashobora. Valve zisanzwe za PVC ntizigomba gukoreshwa ku bushyuhe buri hejuru ya 60°C (140°F). Hejuru y'ubwo bushyuhe, ibikoresho biraroroha kandi bigatakaza ubushobozi bwo kugumana umuvuduko. Ku rundi ruhande, CPVC ikora neza kugeza kuri 93°C (200°F). Ibi bituma iba ibikoresho bisanzwe byo gukoresha amazi ashyushye n'akonje mu nyubako zo guturamo n'iz'ubucuruzi. Irwanya cyane imiti mvaruganda kandi bivuze ko ari amahitamo meza yo gukoresha mu nganda zitunganya amazi, mu nganda zitunganya imiti mvaruganda, no mu nganda aho amazi ashobora kuba akomeye cyane kuri PVC. Ukoresha uburyo bworoshye bwo gukoresha imiti mvaruganda.Valve ya CPVCiyo ukeneye kwemeza ko imikorere n'umutekano bihagaze neza mu gihe cy'ubushyuhe n'imiti.

Ese valve za PVC zishobora guhangana n'umuvuduko mwinshi?

Ugomba guhitamo valve yo gukoresha mu kuhira amazi menshi. Ufite impungenge ko valve ya pulasitiki ishobora kuba idakomeye bihagije kandi ishobora kwangirika bitewe n'umuvuduko w'imikorere y'iyi valve.

Yego,Vali z'umupira za PVCbyagenewe umuvuduko ukabije. Igipimo cyabyo nyacyo, nka PN10 cyangwa PN16, kigaragaza ko bishobora kwihanganira umuvuduko wa 10 cyangwa 16, ariko iki gipimo kiragabanuka uko ubushyuhe bw'amazi bwiyongera.

Iyi ni ingingo y'ingenzi yo gusobanukirwa ku mutekano. Valve ya PN16 PVC ifite amanota yo gufata umuvuduko wa bar 16 (hafi 232 PSI), ibi bikaba bihagije ku mazi menshi. Ariko, iyi ngano ni iy'amazi ari ku bushyuhe bw'icyumba (hafi 20°C). Uko ubushyuhe bw'amazi ari mu muyoboro bugenda buzamuka, ibikoresho bya PVC birushaho koroha gato, kandi ubushobozi bwayo bwo kwihanganira umuvuduko bugabanuka. Urugero, kuri 40°C, valve imwe ya PN16 ishobora kuba nziza kuyikoresha kuri bar 10 gusa. Kuri 60°C, ntarengwa yayo.kugabanuka k'umuvuduko w'igitutukugeza kuri bar 4. Niyo mpamvu utagomba gukoresha valve za PVC ku mazi ashyushye ari munsi y'umuvuduko. Ku bijyanye n'uburyo bwo kuhira bukoresha umuvuduko mwinshi abakiriya ba Budi bakorana nabwo, bukoresha amazi akonje cyangwa ubushyuhe bwo mu kirere, ibipimo ngenderwaho byacuVali z'umupira za PN16 PVCzikomeye kandi zizewe rwose.

Kuki CPVC ihenze kurusha PVC?

Urimo gutegura ikiguzi cy'umukiriya, ukareba ko valve za CPVC zihenda cyane kurusha iza PVC. Umukiriya wawe arimo kubaza impamvu agomba kwishyura amafaranga y'inyongera kuri valve isa hafi ya imwe.

CPVC irahenze cyane kuko inyura mu ntambwe y'inyongera, ikoresha ingufu nyinshi yitwachlorineIyi gahunda y'inyongera yongera ikiguzi ariko igatanga ibikoresho byiza bishobora guhangana n'ubushyuhe bwinshi n'imiti myinshi.

Itandukaniro ry'ibiciro ni ingaruka zitaziguye z'uburyo bwo gukora. Ibikoresho byombi bitangirana na resin ya PVC. Kugira ngo dukore CPVC, tugomba gufata iyo PVC tukayishyira mu buryo bugoye kugira ngo dushyire atome nyinshi za chlorine mu minyururu ya polymer. Ubu buryo busaba ibikoresho byihariye, ibindi bikoresho fatizo (chlorine), n'ingufu nyinshi. Ntabwo wishyura ibara ritandukanye rya pulasitiki gusa; wishyura ubwo buhanga buhanitse. Buri gihe mbwira Budi kubisobanurira abakiriya be nk'ishoramari mu mutekano no mu buryo bwizewe. Ikiguzi cy'inyongera cya valve ya CPVC ni gito ugereranyije n'ikiguzi cyo kwangirika, igihe cyo kudakora, no gusana byabaho iyo bakoresha valve ya PVC ihendutse mu gukoresha amazi ashyushye aho byemejwe ko izananirana. Ni urugero rusanzwe rwo kwishyura amafaranga make ku gikoresho gikwiye akazi.

Ni gute PVC, CPVC, na PP bigereranywa ku ruhande rumwe?

Ukeneye ibisobanuro byihuse kugira ngo ugereranye ibi bikoresho neza. Guhinduranya impapuro zitandukanye z'ibicuruzwa biratesha umutwe kandi bitakaza igihe iyo ukeneye igisubizo cyihuse ku mukiriya.

Iyi mbonerahamwe itanga igereranya risobanutse neza rya PVC, CPVC, na PP mu bipimo by'ingenzi. Igufasha guhitamo ibikoresho bikwiye gukoreshwa mu buryo butunguranye, ikakwereka ko uhuza neza na valve n'akazi.

Kugira ngo ibintu byorohere Budi n'ikipe ye, nashyize hamwe uru rupapuro rw'uburiganya. Ni bwo buryo bwihuse bwo kugereranya ibikoresho twaganiriyeho no gushyiramo Polypropylene (PP), ubundi buryo bw'ingenzi. PP izwiho kurwanya imiti cyane cyane imiti ihumanya ikirere, no kuramba kwayo. Ni amahitamo meza cyane mu nganda no mu biribwa.

Umwanzuro

Guhitamo valve ikwiye biroroshye: koresha PVC mu mazi akonje, CPVC mu mazi ashyushye n'ibindi binyabutabire, na PP mu bikorwa byihariye by'inganda. Guhuza ibikoresho n'akazi bitanga umutekano n'ubwizigirwa.
