Udinga ukukhetha i-valve yebhola, kodwa ukuhlukahluka kuyamangaza. Ukukhetha uhlobo olungalungile kungasho ukulingana okubi, ukuvuza okuzayo, noma isistimu okuyiphupho elibi ukuyinakekela.

Izinhlobo ezine eziyinhloko zama-valve ebhola zihlukaniswa ngokwakhiwa kwemizimba yazo: ucezu olulodwa,iziqephu ezimbili, izingcezu ezintathu, nokungena okuphezulu. Idizayini ngayinye inikeza ibhalansi ehlukile yentengo, amandla, kanye nokulungisa kalula, ukuzivumelanisa nezinhlelo zokusebenza ezithile kanye nezidingo zokunakekela.

Ukuqonda lezi zinhlobo eziyisisekelo kuyisinyathelo sokuqala, kodwa kumane kuyisiqalo. Ngivame ukuba nale ngxoxo no-Budi, umphathi oyinhloko wokuthenga engisebenzisana naye e-Indonesia. Amakhasimende akhe adidwa yiwo wonke amagama. Uthola ukuthi lapho esekwazi ukuchaza umehluko oyinhloko ngendlela elula, amakhasimende akhe azizwa eqiniseka kakhulu. Bangasuka ekubeni nokungaqiniseki baye ekukhetheni uchwepheshe, kungakhathaliseki ukuthi bathenga ivalvu elula yolayini wokunisela noma eyinkimbinkimbi kakhulu yenqubo yezimboni. Ake sihlukanise ukuthi lezi zinhlobo zisho ukuthini kuwe.

Yiziphi izinhlobo ezahlukene zama-valve ebhola?

Ubona amagama anjengokuthi “imbobo egcwele,” “trunnion,” kanye “nebhola elintantayo” kumashidi athile. Le jargon yobuchwepheshe yenza kube nzima ukwazi uma uthola ukusebenza okulungile kwezidingo zakho ezithile.

Ngalé kwesitayela somzimba, ama-valve ebhola abhalwa ngosayizi wawo wokubhoboza (imbobo egcwele uma iqhathaniswa nembobo evamile) kanye nomklamo webhola wangaphakathi (elintantayo vs. trunnion). Imbobo egcwele iqinisekisa ukugeleza okungakhawulelwe, kuyilapho amadizayini e-trunnion ephatha izingcindezi eziphezulu kakhulu.

Masingene sijule kuzo zombili izinhlobo zomzimba nezangaphakathi. Ukwakhiwa komzimba kumayelana nokuthola isondlo. Aucezu olulodwai-valve iyiyunithi evaliwe; ayibizi kodwa ayikwazi ukulungiswa. Aiziqephu ezimbiliumzimba wevalvu uhlukana phakathi, ovumela ukulungiswa, kodwa kufanele uwususe epayipini kuqala. Idizayini enobungane kakhulu yokulungisa iyonaizingxenye ezintathui-valve. Ingxenye emaphakathi equkethe ibhola ingasuswa ngokukhulula amabhawodi amabili, kushiye ukuxhumana kwamapayipi kuqinile. Lokhu kulungele imigqa edinga isevisi njalo. Ngaphakathi, "ichweba" noma imbobo yebhola ibalulekile. Aichweba eligcwelei-valve inembobo elingana nepayipi, okwenza i-zero flow restriction. Aimbobo ejwayelekileincane, ilungele izinhlelo zokusebenza eziningi. Ekugcineni, cishe wonke ama-valve ebhola e-PVC asebenzisa i-aibhola elintantayodesign, lapho ukucindezela kwesistimu kuphusha ibhola ngokuphephile esihlalweni esingezansi ukuze kudaleke uphawu.

Izinhlobo ze-Ball Valve Ngokubuka nje

Yiziphi izinhlobo ezahlukene zokuxhuma kwe-valve yebhola?

Uthole i-valve ephelele, kodwa manje kufanele uyixhume. Ukukhetha indlela yokuxhumana engalungile kungaholela ekufakweni okukhohlisayo, ukuvuza okuqhubekayo, noma isistimu ongeke ukwazi ukusevisa ngayo ngaphandle kwe-hacksaw.

Izinhlobo zokuxhuma ezivame kakhulu zama-valve ebhola amasokhethi e-solvent-weld ebhondi ye-PVC ehlala njalo, iziphetho ezinentambo zokujoyina izinto ezihlukene, iziphetho ezine-flanged zamapayipi amakhulu, nokuxhumana kwenyunyana yangempela ukuze kusebenze kakhulu.

Uhlobo lokuxhuma olukhethayo luchaza ukuthi i-valve ihlanganisa kanjani namapayipi akho.Isokhethinoma izixhumanisi "ezishelelayo" zisetshenziselwa ipayipi le-PVC, ukudala ibhondi ehlala njalo, engavuzi kusetshenziswa usimende oncibilikayo. Lokhu kulula futhi kuthembekile kakhulu.Kufakwe uchungechungeukuxhuma (i-NPT noma i-BSPT) kukuvumela ukuthi ugobe i-valve epayipini elinentambo, elihle kakhulu ukuxhuma i-PVC nezingxenye zensimbi, kodwa kudinga i-sealant yentambo nokufakwa ngokucophelela ukuze kugwenywe ukuvuza. Amapayipi amakhulu (imvamisa angaphezu kwamayintshi angu-2),i-flangedizixhumanisi ziyasetshenziswa. Basebenzisa amabhawudi kanye ne-gasket ukuze bakhe uphawu oluqinile, oluvikelekile, futhi olususeka kalula. Kodwa ukuze ugcine ekugcineni kumapayipi amancane, akukho lutho oludlula aInyunyana Yeqinisoi-valve. Lo mklamo unamantongomane amabili enyunyana akuvumela ukuthi ususe ngokuphelele umzimba omaphakathi wevalvu ukuze ulungiswe noma ushintshwe kuyilapho iziphetho zokuxhuma zihlala zinamathele epayipini. Ihamba phambili kuyo yomibili imihlaba: uxhumano oluqinile nesevisi elula.

Ukuqhathanisa Izinhlobo Zokuxhuma

Yiziphi izinhlobo ezahlukene zama-valve e-MOV?

Ufuna ukwenza isistimu yakho ibe ngokuzenzakalela, kodwa i-"MOV" izwakala njengemishini yezimboni eyinkimbinkimbi. Awunasiqiniseko mayelana nomthombo wamandla, izinketho zokulawula, futhi uma zisebenza kuphrojekthi yakho.

I-MOV imeleI-Motorized Operated Valve, okuyinoma iyiphi i-valve elawulwa i-actuator. Izinhlobo ezimbili eziyinhloko ama-actuator kagesi, asebenzisa i-motor kagesi, nama-pneumatic actuators, asebenzisa umoya ocindezelwe ukusebenzisa i-valve.

I-MOV ayilona uhlobo olukhethekile lwevalvu; iyivalvu ejwayelekile ene-actuator efakwe kuyo. Uhlobo lwe-actuator yilo olubalulekile.Ama-actuator kagesiyizona ezivame kakhulu kuma-valve ebhola e-PVC ezinhlelweni zamanzi. Basebenzisa injini encane ukuvula ivalvu noma ivaleke futhi ayatholakala ngama-voltage ahlukahlukene (njenge-24V DC noma 220V AC) ukuze afane nomthombo wakho wamandla. Zilungele izinhlelo zokusebenza ezifana nezindawo zokunisela ezizenzakalelayo, umthamo wokwelashwa kwamanzi, noma ukugcwalisa ithangi elikude.Ama-actuator we-pneumaticsebenzisa amandla omoya ocindezelwe ukuvula ivalvu noma ivaleke ngokushesha okukhulu. Zinamandla ngokwedlulele futhi zithembekile kodwa zidinga i-compressor yomoya nemigqa yomoya ukuze zisebenze. Ngokuvamile uzibona kuphela ezitshalweni ezinkulu zezimboni lapho umoya ocindezelwe usuvele uyingxenye yengqalasizinda. Kumakhasimende amaningi e-Budi, ama-actuator kagesi ahlinzeka ngebhalansi efanelekile yokulawula, izindleko, kanye nokulula.

Uyini umehluko phakathi kwe-valve yebhola yohlobo 1 nohlobo 2?

Ufunda ishidi elicacisiwe futhi ubone “Ivaluthi Yebhola Yohlobo 21” futhi awazi ukuthi kusho ukuthini lokho. Ukhathazekile ngokuthi kungenzeka ushoda ngemininingwane ebalulekile mayelana nokuphepha noma ukusebenza kwayo.

Leli gama lamagama ngokuvamile libhekisela ezizukulwaneni zama-valve ebhola lezinyunyana ezivela kumikhiqizo ethile. “Uhlobo 21″ seluphenduke isifinyezo sedizayini yesimanjemanje, esebenza kahle ehlanganisa izici ezibalulekile zokuphepha nezici zokusebenziseka ezifana nenathi lenyunyana elivikelekile.

Amagama athi “Uhlobo 1″ noma “Uhlobo 21″ awawona amazinga ajwayelekile kubo bonke abakhiqizi, kodwa asho imiklamo enethonya emise imakethe. Cabanga “ngohlobo 21″ njengokumelela izinga lesimanjemanje, eliphambili levalvu yenhlangano yangempela. Lapho siklama amavalvu ethu e-Pntek true union, sahlanganisa izimiso ezenza lezi zakhiwo zibe zinhle kakhulu. Isici esibaluleke kakhuluI-Block-Safe Union Nut. Lena indlela yokuphepha lapho inathi linentambo yokukhiya, okwenza kube nzima ukuqaqa ngephutha futhi uvule isistimu ngenkathi ingaphansi kwengcindezi. Lokhu kuvimbela ukuqhuma okuyingozi. Ezinye izici ezivamile zalesi sitayela zihlanganisaIziqu ezimbili O-izindandathoukuvikela ukuvuza okuphezulu esibambo kanye neiphedi yokufaka ehlanganisiwe(imvamisa ibe yizinga le-ISO 5211) okwenza kube lula ukwengeza i-actuator kagesi ngokuhamba kwesikhathi. Akuyona nje i-valve; iyingxenye yesistimu ephephile, enokwethenjelwa kakhudlwana, futhi enobufakazi besikhathi esizayo.

Isiphetho

Izinhlobo ezine zama-valve eziyinhloko zibhekisela kwisitayela somzimba, kodwa ukuqonda kwangempela kuvela ekwazini imbobo, uxhumo, nezinketho zokusebenzisa. Lolu lwazi lukuvumela ukuthi ukhethe i-valve ephelele yanoma yimuphi umsebenzi.
