Uzabalaza ukuthemba ama-valve ebhola e-PVC kumaphrojekthi akho? Ukwehluleka okukodwa kungabangela umonakalo obizayo nokubambezeleka. Ukuqonda ukwethembeka kwabo kwangempela kuyisihluthulelo sokwenza isinqumo sokuthenga ngokuzethemba.
Yebo, ama-valve ebhola e-PVC athembeke kakhulu ekusetshenzisweni kwawo okuhlosiwe, ikakhulukazi emanzini kanye nezinhlelo zokunisela. Ukuthembeka kwazo kuvela ekwakhiweni okulula, kodwa kuncike kakhulu ekuzisebenziseni phakathi kwengcindezi yazo efanele nezinga lokushisa, ukufakwa okufanele, nokukhetha umkhiqizi wekhwalithi.
Eminyakeni yami yokuphatha inkampani yokubumba nokuhweba, ngibe nezingxoxo ezingenakubalwa mayelana nokuthembeka komkhiqizo. Ngivame ukucabanga ngoBudi, umphathi wokuthenga obukhali ovela kumsabalalisi omkhulu wase-Indonesia. Wayenomthwalo wemfanelo wokuthola inqwaba yamavalvu e-PVC, futhi ukukhathazeka kwakhe okukhulu kwakuwulula nje: “Kimmy, ngingawethemba lawa? Wayedinga okungaphezu kokuthi uyebo noma cha. Kwakudingeka aqonde ukuthi “kungani” nokuthi “kanjani” ngemuva kokusebenza kwabo ukuze avikele ibhizinisi lakhe kanye namakhasimende akhe. Lesi sihloko sichaza ngqo lokho engabelana ngakho naye, ukuze nawe ukwazi ukuthola umthombo ngokuzethemba.
Athembeke kangakanani ama-valve ebhola e-PVC?
Uzwa izindaba ezingqubuzanayo mayelana nokusebenza kwevalvu ye-PVC. Ukukhetha i-valve ngokusekelwe enanini kuphela kungaholela ekuhlulekeni ngaphambi kwesikhathi kanye nokulungiswa okubizayo. Yazi imikhawulo yabo yomhlaba wangempela ukuze uqinisekise impumelelo.
Ama-valve ebhola e-PVC athembeke kakhulu uma esetshenziswa ngendlela efanele. Basebenza kahle kakhulu ngaphansi kuka-150 PSI no-140°F (60°C). Idizayini yazo elula izenza ziqine kumasevisi afana namanzi, kodwa azifanele uketshezi olunezinga lokushisa eliphezulu, izinto ezilimazayo, noma amakhemikhali athile anolaka angalimaza i-PVC.
Lapho uBudi engibuza ngokwethembeka, ngamtshela ukuthi acabange ngakho njengokukhetha ithuluzi elifanele lomsebenzi. Ubungeke usebenzise i-screwdriver ukubethela isipikili. Ngokufanayo, aUkuthembeka kwe-valve ye-PVCkumnandi, kodwa kuphela ngaphakathi kwewindi layo lokusebenza eliklanyelwe. Izingxenye ezibalulekile zisebenza ndawonye ukuze zilethe lokhu kusebenza. Umzimba we-PVC uhlinzeka ngobuqotho besakhiwo kanye nokumelana nokugqwala, kuyilapho izimpawu zangaphakathi, ngokuvamile zenziweI-PTFE (Teflon), qinisekisa ukuvala okuqinile. Isiqu O-rings, ngokuvamileI-EPDM noma i-Viton (FKM), vimbela ukuvuza endaweni yokubamba. Uma ukhetha i-valve kumkhiqizi ohloniphekile, lezi zinto zisezingeni eliphezulu futhi zihlangabezana nezindinganiso zamazwe ngamazwe njenge-ASTM, eqinisekisa izinga elithile lokusebenza. Yile nhlanganisela yomklamo olula kanye nezinto zekhwalithi ezibenza babe ihhashi elithembekile lezimboni eziningi.
Izinto ezibonakalayo kanye Nomklamo
Ukuthembeka kuqala ngezinto zokwakha. I-PVC (i-Polyvinyl Chloride) imelana ngokwemvelo nokugqwala emanzini, usawoti, nama-acid amaningi nezisekelo. Ibhola ngaphakathi lizungeza ngokushelelayo ngokumelene nezihlalo ze-PTFE, into eyaziwa ngokungqubuzana okuphansi. Lokhu kusho ukuguga okuncane kanye nokudilika phezu kwezinkulungwane zemijikelezo.
Imikhawulo yokusebenza ibalulekile
Ukwehluleka okuningi engikubonile kwenzeka lapho i-valve iphushwa ngaphezu kwemingcele yayo. Ukucindezela okuphezulu kungacindezela umzimba we-valve, kuyilapho izinga lokushisa eliphezulu lingathambisa i-PVC, ibangele ukuba igogeke futhi ivuze. Njalo hlola imininingwane yomkhiqizi ephrintiwe emzimbeni wevalvu.

Ingabe ama-valve ebhola e-PVC ayahluleka?
Ukhathazeka ngokuthi kungenzeka yini ukwehluleka kwe-valve kungazelelwe, okuyinhlekelele. I-valve eyodwa embi ingamisa wonke umsebenzi. Ungakugwema lokhu ngokuqonda ukuthi kungani behluleka futhi kanjani.
Yebo, ama-valve ebhola e-PVC angakwazi futhi ahluleke. Kodwa-ke, ukwehluleka cishe njalo kubangelwa izici zangaphandle, hhayi iphutha ku-valve ngokwayo. Izizathu ezivame kakhulu ukulimala ngokomzimba, ukusebenzisa i-valve ngaphandle kwengcindezi noma izinga lokushisa, ukungahambisani kwamakhemikhali, nokuwohloka kwe-UV.
Ngake ngasebenza neklayenti emsebenzini omkhulu wokunisela owabhekana nochungechunge lwezinkinga. Wayekhungathekile, ecabanga ukuthi uthenge inqwaba yama-valve amabi. Lapho ngiya endaweni, ngathola ukuthi inkinga kwakungewona ama-valve, kodwa ukufakwa. Abasebenzi bebesebenzisa ama-wrenches amakhulu futhi beqinisa ama-valve anentambo ngamandla amakhulu, okubangela ukuqhekeka kwezinwele emizimbeni yama-valve. Le mifantu emincane yayizobamba isikhashana kodwa yayizohluleka ngemva kwamasonto ngaphansi kwengcindezi evamile yokusebenza. Ngokunikeza ukuqeqeshwa okulula kokuqinisa isandla kanye nokujika kwekota, siyisuse ngokuphelele inkinga. Lokhu kwangifundisa isifundo esibalulekile: ukwehluleka ngokuvamile kuwuphawu lwendaba evinjelwayo. KuBudi, ukunikeza lolu hlobo lolwazi kumakhasimende akhe kwaba yindlela yokwengeza inani nokwakha ukwethembeka.
Ukulimala Komzimba kanye namaphutha okufaka
Lesi yimbangela yokuqala yokwehluleka engiyibonayo. Ukuqinisa kakhulu ukuxhumana okunentambo kuyiphutha lakudala. Okunye akuvumeli ukusekelwa okufanele kwamapayipi, okubeka ukucindezeleka ku-valve. Ukubanda kuphinde kube isitha esikhulu; amanzi anda lapho eba yiqhwa, futhi angaqhekeka kalula i-valve ye-PVC ngaphakathi.
Ukuwohloka Kwezinto Ezibalulekile
| Imodi yokwehluleka | Imbangela evamile | Ithiphu Lokuvimbela |
|---|---|---|
| Ukuqhekeka | Ukuqinisa ngokweqile, umthelela, amanzi aqandayo. | Qinisa ngesandla bese unikeza ithuba lekota. Gxilisa noma ukhiphe imigqa esimweni sezulu esibanda. |
| Bamba Ukuphuka | Ukusebenzisa amandla amakhulu, ukuchayeka kwe-UV kushintsha ipulasitiki ibe brittle. | Sebenzisa isibambo ngokushelela. Sebenzisa ama-valve amelana ne-UV noma uwapende ukuze asetshenziswe ngaphandle. |
| Ukuhlasela Kwamakhemikhali | Uketshezi aluhambisani ne-PVC, i-EPDM, noma i-FKM. | Njalo hlola ishadi lokuhambisana namakhemikhali ngaphambi kokukhetha ivalvu. |
I-Seal kanye ne-Component Wear
Nakuba ziqinile, izimpawu zangaphakathi zingagcina ziguge ngemva kwezinkulungwane eziningi zemijikelezo, nakuba lokhu kuyivelakancane ezinhlelweni eziningi. Imvamisa, udoti njengesihlabathi noma inhlabathi ingena emugqeni bese iklwebha izihlalo ze-PTFE noma ibhola ngokwalo. Lokhu kudala indlela yokuthi amanzi avuze ngisho nalapho i-valve ivaliwe. Isihlungi esilula esikhuphuka nomfula singanqanda lolu hlobo lokwehluleka.
Yini eyenza i-valve yebhola ye-PVC ivuze?
Ukuconsa kancane okuvela ku-valve kuyinkinga evamile kodwa engathi sína. Lokho kuvuza okuncane kungaholela ekulimaleni kwamanzi, ukulahlekelwa umkhiqizo, kanye nezingozi zokuphepha. Ukukhomba imbangela kusemqoka.
Ukuvuza kuma-valve ebhola e-PVC ngokuvamile kubangelwa enye yezinto ezintathu: izimpawu zangaphakathi ezilimele (ama-O-rings noma izihlalo), ukufakwa okungalungile okuholela ekuxhumekeni okubi, noma ukuqhekeka emzimbeni we-valve ngokwawo. Imfucumfucu engaphakathi kwevalvu nayo ingavimbela ukuthi ivaleke ngokugcwele.
Uma ikhasimende libika ukuvuza, ngihlala ngilicela ukuthi likhombe lapho livela khona. Indawo okuvuza kuyo ikutshela konke. Ingabe liyaconsa lisuka lapho isibambo singena khona emzimbeni? Lokho kuyinto yakudalaisiqu O-ring udaba. Ingabe ivuza lapho i-valve ixhuma khona epayipini? Lokho kukhomba iphutha lokufaka. Noma ingabe amanzi asageleza lapho i-valve ivaliwe? Lokho kusho ukuthi uphawu lwangaphakathi lusengozini. Ukuqonda lezi ezahlukeneamaphuzu avuzayoibalulekile ekuxazululeni izinkinga. Eqenjini lika-Budi, ukukwazi ukubuza le mibuzo kubasiza ukuthi banikeze ukwesekwa kwamakhasimende okungcono kakhulu, ukuhlonza ngokushesha uma kuyinkinga yomkhiqizo (okuyivelakancane kakhulu) noma inkinga yokufaka noma yohlelo lokusebenza (evame kakhulu).
Ukuvuza kwe-Valve Stem
Isiqu wumphini oxhuma isibambo nebhola. Ivalwe nge-O-rings eyodwa noma ezimbili. Ngokuhamba kwesikhathi, noma ngokuchayeka kukhemikhali engahambelani, lawa ma-O-rings angehlisa izinga futhi alahlekelwe ikhono lawo lokuvala, abangele ukuconsa okuhamba kancane okuvela eduze kwesibambo. Kwamanye amavalvu esitayela “senyunyana yeqiniso”, inadi eliphethe elibambe isiqu lingaqiniswa ukuze kucindezela ama-O-rings futhi kumiswe ukuvuza okuncane.
Ukuvuza Ekuxhumekeni
Konke lokhu kumayelana nokufakwa. Ekuxhumekeni kwe-solvent-weld (enamathiselwe), ukuvuza kwenzeka uma kusimende okungalungile kusetshenziswe, uma ipayipi nokufaka kungazange kuhlanzwe kahle, noma uma usimende unganikezwanga isikhathi esanele sokuphulukisa ngaphambi kokucindezela umugqa. Ngoxhumo oluluchungechunge, ukuvuza kwenzeka kusukela ekuqinisweni ngaphansi, ukuqinisa kakhulu (okubangela ukuqhekeka), noma ukungasebenzisi itheyiphu eyanele ye-PTFE ukuvala imicu.
Ukuvuza Kudlule I-Ball Seal
| Indawo yokuvuza | Imbangela okungenzeka | Indlela Yokulungisa Noma Ukuvimbela |
|---|---|---|
| I-Valve Stem | Isiqu se-O-ring esigugile noma esilimele. | Faka esikhundleni i-O-ring noma i-valve yonke. Khetha okubalulekile kwe-O-ring (EPDM/FKM). |
| Ipayipi Connection | I-gluing engalungile; i-thread sealant enganele; ukulinganisa okuqhekekile. | Yenza kabusha uxhumano ngendlela efanele. Qinisekisa isikhathi esifanele sokuphulukisa i-glue. Ungaqinisi kakhulu imicu. |
| Ngevavu (Ivaliwe) | Imfucumfucu ngaphakathi; ibhola eliklwetshiwe noma izihlalo. | Zama ukuhamba ngebhayisikili i-valve ukuze ukhiphe imfucumfucu. Faka isihlungi esikhuphuka nomfula ukuze uvikele i-valve. |
Isiphetho
Ngamafuphi, ama-valve ebhola e-PVC anikeza ukwethembeka okuvelele kanye nenani uma esetshenziswe ngendlela efanele. Ukuqonda imikhawulo yabo kanye nokuqinisekisa ukufakwa okufanele yizihluthulelo zokusebenzisa amandla abo aphelele.
