Ugomba kugura valve za PVC ku mushinga, ariko kataloge iragoye cyane. Umupira, icyerekezo, ikinyugunyugu, diaphragm—guhitamo ikosa bivuze ko sisitemu iva, inanirwa, cyangwa idakora neza.

Ubwoko bw'ingenzi bwa valve za PVC bushyirwa mu byiciro hakurikijwe imikorere yazo: valve z'umupira zo kugenzura no kuzimya, valve zo kugenzura kugira ngo wirinde gusubira inyuma, valve z'ibinyugunyugu zo gufunga imiyoboro minini, na valve z'inyuma zo gufata amazi yangiza cyangwa asukuye.

Iki ni ikibazo nkunda kuganiraho n'abafatanyabikorwa banjye, barimo Budi, umuyobozi mukuru ushinzwe kugura muri Indoneziya. Abakiriya be, kuva ku ba rwiyemezamirimo kugeza ku bacuruzi, bagomba kumenya ko babonye igikoresho gikwiye cyo gukora akazi.sisitemu y'amaziikomeye nk'uko igice cyayo cy'intege nke gikomera, kandi igahitamo igikwiyeubwoko bwa valveni intambwe ya mbere igana ku kubaka sisitemu yizewe kandi irambye. Gusobanukirwa aya tandukaniro si ubumenyi bwa tekiniki gusa; ni ishingiro ry'umushinga ugenda neza.

Ese hari ubwoko butandukanye bwa valve za PCV?

Wumva ijambo "valve ya PVC" maze ugatekereza ko ari ikintu kimwe gisanzwe. Iki gitekerezo gishobora gutuma ushyiraho valve idashobora kwihanganira umuvuduko cyangwa ngo ikore akazi ukeneye.

Yego, hari ubwoko bwinshi bwa valve za PVC, buri imwe ifite uburyo bwihariye bw'imbere bwagenewe akazi runaka. Ikunze gukoreshwa cyane ni iyo gutangira/guhagarika gutemba (valve z'umupira) no gukumira mu buryo bwikora gutemba inyuma (valve zo kugenzura).

Gutekereza ko valve zose za PVC ari zimwe ni ikosa risanzwe. Mu by'ukuri, igice cya "PVC" kivuga gusa ibikoresho valve ikoramo - pulasitiki iramba kandi idakonjesha. Igice cya "valve" kivuga akazi kayo. Kugira ngo dufashe Budi n'ikipe ye kuyobora abakiriya babo, turabasesengura dukurikije inshingano zabo z'ibanze. Uku gushyira mu byiciro byoroshye bifasha buri wese guhitamo ibicuruzwa bikwiye afite icyizere.

Dore isesengura ry'ibanze ry'ubwoko busanzwe uzahura nabwo mu gucunga amazi:

Ubwoko bune bwa PVC ni ubuhe?

Ubona amabati atandukanye nka PVC-U na C-PVC ukibaza niba afite akamaro. Gukoresha valve isanzwe mu murongo w'amazi ashyushye kuko utari uzi itandukaniro bishobora guteza ikibazo gikomeye.

Iki kibazo kireba ibikoresho bya pulasitiki, ntabwo ari ubwoko bwa valve. Ibikoresho bine bihuriweho na PVC-U (bisanzwe, ku mazi akonje), C-PVC (ku mazi ashyushye), PVC-O (ingufu nyinshi), na M-PVC (byahinduwe n'ingaruka).

Iki ni ikibazo cyiza cyane kuko kigera ku ireme ry'ibicuruzwa n'umutekano wabyo. Gutandukanya ubwoko bw'amavalufe n'ubwoko bw'ibikoresho biroroshye. Muri Pntek, twizera ko umufatanyabikorwa wize ari umufatanyabikorwa watsinze, bityo kubisobanura neza ni ingenzi. Ibikoresho amavalufe yawe akorerwamo bigena ubushyuhe bwayo, igipimo cy'umuvuduko, n'ubudahangarwa bwayo mu binyabutabire.

PVC-U (Polyvinyl Chloride idakozwe muri pulasitiki)

Ubu ni bwo bwoko bwa PVC bukunze gukoreshwa cyane mu miyoboro, ibikoresho, na za valve muri Amerika ya Ruguru, i Burayi na Aziya. Burakomeye, buhendutse, kandi burwanya cyane imiti itandukanye. Ni bwo buryo busanzwe bwo gukoresha mu mazi akonje. Inyinshi muri za valve zacu za Pntek ball na check valves Budi itumiza zikozwe muri PVC-U yo mu rwego rwo hejuru.

C-PVC (Polyvinyl Chloride ifite Chloride)

C-PVC inyura mu nzira y’inyongera ya chlorine. Iyi mpinduka yoroshye yongera cyane ubushobozi bwayo bwo kudakoresha ubushyuhe. Nubwo PVC-U igomba gukoreshwa gusa kugeza kuri 60°C (140°F), C-PVC ishobora kwihanganira ubushyuhe bugera kuri 93°C (200°F). Ugomba gukoresha valve za C-PVC ku miyoboro y’amazi ashyushye.

Andi moko

PVC-O (Ifite umurongo) na M-PVC (Yahinduwe) ntabwo bikunze kugaragara kuri valves ahubwo bikunze kugaragara cyane ku miyoboro yihariye y'umuvuduko, ariko ni byiza kumenya ko ihari. Yakozwe kugira ngo igire igipimo cy'umuvuduko mwinshi kandi irusheho kugira imbaraga.

Ni ubuhe bwoko butandatu bw'ingenzi bwa valves?

Urimo kubaka sisitemu igoye kandi ukeneye ibirenze gusa valve yoroshye yo kuyifungura no kuyifunga. Kubona amazina nka "Globe" cyangwa "Gate" bishobora gutera urujijo niba ukoresha cyane cyane valve za PVC.

Imiryango itandatu y'ingenzi y'ama-valve ni Ball, Gate, Globe, Check, Butterfly, na Diaphragm. Inyinshi muri zo ziboneka muri PVC kugira ngo zikoreshwe mu gihe ama-valve y'icyuma yakwangirika cyangwa akaba ahenze cyane.

Nubwo twibanda ku bwoko bwa PVC busanzwe, gusobanukirwa umuryango wose wa valve bigufasha kumenya impamvu valve zimwe na zimwe zitoranywa kurusha izindi. Zimwe ni amahame ngenderwaho mu nganda, izindi ni iz'akazi runaka. Ubu bumenyi bwagutse bufasha itsinda rya Budi gusubiza ndetse n'ibibazo by'abakiriya birambuye.

Ku bijyanye no gucunga amazi muri rusange,valve z'umupira, valve zo kugenzuranavalve z'ibinyugunyuguni ubwoko bw'ingenzi bwa PVC ugomba kumenya.

Ni ubuhe bwoko butandukanye bwa valve zo gusuzuma za PVC?

Ukeneye valve yo kugenzura kugira ngo wirinde gusubira inyuma kw'amazi, ariko ubona amahitamo nka "swing," "ball," na "spring." Gushyiramo iyitari yo bishobora gutuma habaho kwangirika, inyundo y'amazi, cyangwa valve ntikore na gato.

Ubwoko bw'ingenzi bwa PVC check valves ni swing check, ball check, na spring check. Buri imwe ikoresha uburyo butandukanye bwo guhagarika gusubira inyuma kandi ikwiranye n'icyerekezo gitandukanye cy'imiyoboro n'imiterere y'amazi.

Valve yo kugenzura ni umurinzi utagira icyo utangaza wa sisitemu yawe, ikora mu buryo bwikora nta migozi cyangwa ingufu zo hanze. Ariko si abarinzi bose bakora kimwe. Guhitamo ikwiye ni ingenzi cyane mu kurinda pompe no kurinda sisitemu. Iyi ni ingingo nkunda gushimangira kuri Budi, kuko igira ingaruka ku buryo butaziguye ku kwizerwa kw'ibikoresho by'abakiriya bayo mu gihe kirekire.

Valve yo kugenzura Swing ya PVC

Ubu ni bwo bwoko bworoshye cyane. Bufite agace gafite aho kabogamiye (cyangwa disiki) gafunguka iyo amazi atemba. Iyo amazi atemba cyangwa agasubira inyuma, imbaraga rukuruzi n'umuvuduko w'umugongo bizunguza agace gafite aho kabogamiye. Bikora neza mu miyoboro itambitse cyangwa mu miyoboro ihagaze ifite amazi atemba hejuru.

Valve yo gusuzuma umupira wa PVC

Ubu ni umwihariko wacu muri Pntek. Umupira w’uruziga uba mu cyumba. Umupira utemba imbere utuma umupira usohoka mu nzira y’umuvuduko. Iyo umuvuduko usubiye inyuma, usubiza umupira mu ntebe, bigatuma upfundikira neza. Ni uwizerwa cyane, ushobora gushyirwaho uhagaze cyangwa utambitse, kandi nta mapine cyangwa imigozi bifite yo kwangirika.

Valve yo kugenzura impeshyi ya PVC

Ubwo bwoko bukoresha isoko kugira ngo bufashe gufunga valve vuba iyo amazi ahagaze. Iki gikorwa cyo gufunga vuba ni cyiza cyane mu gukumira inyundo y'amazi—umuraba wangiza uterwa no guhagarika gutunguranye kw'amazi. Bishobora gushyirwa mu cyerekezo icyo ari cyo cyose.

Umwanzuro

Guhitamo valve ya PVC ikwiye bivuze gusobanukirwa ubwoko bwayo—umupira wo kugenzura, kugenzura niba ikora neza—n'ibikoresho bya pulasitiki ubwabyo. Ubu bumenyi butuma sisitemu ikora neza, bukarinda gutsindwa, kandi bukongera icyizere cy'abakiriya.
