Ivalvu yenzani?

Ivalvu yinto enamathiselwe emapayipini esetjenziselwa ukuvula nokuvala amapayipi, ukulawula indlela yokugeleza, ukulawula nokulawula amapharamitha (amazinga womtjhiso, umfutho kanye nezinga lokugeleza) lendawo edluliselwako. Ngokuya ngomsebenzi wayo, ingahlukaniswa ibe zivalvu zokuvala,amavalvu wokuhlola, amavalvu wokulawula, njll.

Amavalvu ziingcenye zokulawula eenhlelweni zokuthutha amanzi, ezinemisebenzi yokuvala, ukulawula, ukuphambukisa, ukukhandela ukugeleza emuva, ukuqinisa umfutho, ukuphambukisa nofana ukuqeda umfutho wokuphuphuma. Amavalvu weenhlelo zokulawula amanzi athoma emavalvuni alula khulu wokuvala ukuya emavalvuni ahlangahlangeneko asetjenziswa eenhlelweni zokulawula ezizenzakalelayo.

Amavalvu angasetjenziselwa ukulawula ukugeleza kwemihlobo ehlukileko yamanzi afana nomoya, amanzi, umtjhiso, izinto ezihlukahlukeneko ezibolako, ama-slurries, amafutha, iinsimbi ezimanzi kanye nezinto ezikhiqiza imisebe. Ngokuya ngezinto ezisetjenziswako, amavalvu nawo ahlukaniswe abeamavalvu wensimbi, amavalvu wensimbi, amavalvu ensimbi engagqwali (201, 304, 316, njll.), amavalvu wensimbi we-chrome-molybdenum, amavalvu wensimbi ye-chromium-molybdenum vanadium, amavalvu wensimbi we-duplex, amavalvu weplastiki, amavalvu we-non-standard customized, njll.

Ngomsebenzi nokusetjenziswa

(1) Ivalvu yokuvala

Umhlobo lo wevalvu usetjenziselwa ukuvula nokuvala. Ifakwe unomphela ekungeneni nasekuphumeni kwemithombo yamakhaza nokutjhisa, ekungeneni nasekuphumeni kwemitjhini, kanye negatja lamapayipi (okufaka hlangana ama-riser), begodu ingasetjenziswa njengevalvu yokukhipha amanzi kanye nevalvu yokukhupha umoya. Amavalvu avamileko wokuvala afaka hlanganaamavalvu wesango, amavalvu we-globe, amavalvu webhola kanye namavalvu we-butterfly.

Amavalvu wesangoingahlukaniswa ibe yinduku evulekileko nenduku emnyama, inkunzi eyodwa neenkunzi ezimbili, inkunzi ye-wedge nenkosi ekhambelanako, njll. Ukuqina kwevalvu yesango akukalungi, begodu kubudisi ukuvula ivalvu yesango enobubanzi obukhulu; Ubukhulu bomzimba wevalvu buncani ngokuya ngendlela amanzi ageleza ngayo, ukujamelana nokugeleza kuncani, begodu ububanzi bevalvu yesango bukhulu.

Ngokuya ngendlela yokugeleza kwe-medium, ivalvu ye-globe ihlukaniswe yaba mihlobo emithathu: umhlobo oqondileko, umhlobo one-angle elungileko kanye nomhlobo wokugeleza okuqondileko, begodu kuneentonga ezivulekileko neentonga ezimnyama. Ukuqina kokuvala kwevalvu ye-globe kungcono kunaleyo yevalvu yesango, umzimba wevalvu mude, ukujamelana nokugeleza kukhulu, begodu ububanzi obukhulu buyi-DN200.

I-spool ye-valve yebholo yibholo evulekileko. Isiqu sevalvu esisebenza ngepuleti senza ibholo ivuleke lokha nayiqalene ne-eksisi yepayipi, begodu ivaleka ngokupheleleko lokha nayijika nge-90°. Ivalvu yebholo inokusebenza okuthileko kokulungisa begodu ivala ngokuqinileko.

I-spool yeivalvu yevivaneyidiski eyindilinga ejikeleza eduze neshafti ejame ngqo ye-eksisi yepayipi ejame ngqo. Lokha isibhakabhaka sepuleti yevalvu sivumelana ne-eksisi yepayipi, ivulekile ngokupheleleko; Lokha indiza ye-ram nayijamelene ne-eksisi yepayipi, ivaliwe ngokupheleleko. Ubude bomzimba we-butterfly valve buncani, ukujamelana nokugeleza kuncani, begodu intengo iphezulu kunaleyo yama-gate valve nama-globe valve.

(2) Hlola ivalvu

Umhlobo lo wevalvu usetjenziselwa ukukhandela ukugeleza emuva kwe-medium, begodu usebenzisa amandla we-fluid ukuzivulela begodu uvale ngokuzenzakalelako lokha nakugeleza ngendlela ehlukileko. Ukuma ekuphumeni kwepompo, ekuphumeni kwesithiyo, nezinye iindawo lapho ukugeleza okubuyela emuva kwe-fluid kungavunyelwa khona. Kuneentlobo ezintathu zamavalvu wokuhlola: umhlobo wokuvula ngokujikeleza, umhlobo wokuphakamisa kanye nomhlobo we-clamp. Endabeni yamavalvu wokuhlola ajikajikako, amanzi angageleza ukusuka ngesinceleni ukuya ngesidleni begodu avale ngokuzenzakalelayo lokha nakageleza ngendlela ehlukileko. Emavalvu wokuhlola ukuphakama, i-spool iphakama phezulu ukwenza indlela njengombana uketshezi lugeleza ukusuka ngesinceleni ukuya ngesidleni, begodu i-spool ivalwa lokha nayigandelelwe esihlalweni lokha ukugeleza kubuyiselwa emuva. Nge-valve yokuhlola e-clamp-on, lokha uketshezi nalugeleza ukusuka ngesinceleni ukuya ngesidleni, umgogodla wevalvu uvulwa ukwenza indlela, bese umgogodla wevalvu ucindezelwa esihlalweni sevalvu bese uvalwa lokha ukugeleza okubuyela emuva kubuyiselwa emuva.

(3) Ukulawulaamavalvu

Umehluko womfutho hlangana kwangaphambili nangemuva kwevalvu uqinisekile, begodu lokha nakuvulwa kwevalvu ejayelekileko kutjhuguluka ngebanga elikhulu, izinga lokugeleza litjhuguluka kancani, begodu lokha nalifinyelela ekuvulekeni okuthileko, izinga lokugeleza litjhuguluka khulu, okutjho bona, ukusebenza kokulungisa akukalungi. Ivalvu yokulawula ingatjhugulula i-spool stroke ukutjhugulula ukujamelana kwevalvu ngokuya ngendlela nobukhulu besiginali, ukwenzela bona kuzuzwe umnqopho wokulawula ivalvu yokugeleza. Amavalvu wokulawula ahlukaniswe ngamavalvu wokulawula ngesandla namavalvu wokulawula ngokuzenzakalelako, begodu kunemihlobo eminengi yamavalvu wokulawula ngesandla nofana ngokuzenzakalelako, begodu ukusebenza kwawo kokulungisa nakho kuhlukile. Amavalvu wokulawula ngokuzenzakalelako afaka hlangana amavalvu wokulawula ukugeleza asebenza ngokwawo kanye namavalvu wokulawula umfutho ohlukileko asebenza ngokwawo.

(4) I-vacuum

I-vacuum ifaka hlangana amavalvu we-vacuum ball, ama-vacuum baffle, ama-vacuum inflation valve, ama-vacuum valve, njll. Umsebenzi wayo usehlelweni le-vacuum, i-elementi yesistimu ye-vacuum esetjenziselwa ukutjhugulula indlela yokugeleza komoya, ukulungisa ivolumu yokugeleza komoya, ukusika nofana ukuxhuma iphayiphi ibizwa ngokuthi yi-vacuum valve.

(5) Iinkoro ezikhethekileko

Iinkoro ezikhethekileko zifaka hlangana amavalvu wengulube, amavalvu wokukhipha umoya, amavalvu wokuphefumula, amavalvu wokukhipha ummoya, amafiltha, njll.

Ivalvu yokukhipha ummoya yingcenye eqakathekileko ehlelweni lamapayipi, esetjenziswa khulu emabhoyileni, eemoyeni, emafutheni negesi, emapayipini wokuphakelwa kwamanzi kanye namapayipi wokukhipha amanzi. Ivamise ukufakwa endaweni ephakemeko nofana ngendololwane ukususa igesi enengi ngaphakathi kwepayipi, ukwenza ngcono ukusetjenziswa kwepayipi nokwehlisa ukusetjenziswa kwamandla.
