Ama-valve okuhlola, aziwa nangokuthi ama-valve angabuyisi (ama-NRV), ayingxenye ebalulekile yanoma yiluphi uhlelo lwamapayipi ezimboni noma lwezindlu. Asetshenziselwa ukuvimbela ukugeleza kwamanzi emuva, ukuqinisekisa ukusebenza kahle kohlelo kanye nokuvimbela umonakalo.

Ama-check valve asebenza kalula. Ingcindezi edalwa uketshezi olugeleza ohlelweni lwamapayipi ivula i-valve, futhi noma yikuphi ukugeleza okuphambene kuvala i-valve. Ivumela uketshezi ukuthi lugeleze ngaphandle kokuvinjelwa ngokuphelele ohlangothini olulodwa futhi luvale ngokuzenzakalelayo lapho ingcindezi incishisiwe. Nakuba lokhu kulula, kunezinhlobo ezahlukene zama-check valve anemisebenzi ehlukene kanye nezinhlelo zokusebenza. Wazi kanjani ukuthi yiluphi uhlobo lwe-check valve okufanele ulusebenzise emsebenzini wakho noma kuphrojekthi yakho? Ukuze sikusize wenze ukukhetha okufanele, nansi eminye imininingwane ngezinhlobo ezivame kakhulu zama-check valve.

I-valve yokuhlola i-swing
I-White PVC Swing CheckSwing Check Valve isebenzisa idiski ngaphakathi kwevalvu ukuvumela noma ukumisa ukugeleza ohlelweni lwamapayipi. Uma uketshezi lugeleza ngendlela efanele, ingcindezi iphoqa idiski ukuthi ivuleke futhi ihlale ivulekile. Njengoba ingcindezi yehla, idiski yevalvu iyavalwa, ivimbele ukugeleza koketshezi okuphambene. Amavalvu okuhlola i-Swing atholakala ngezinhlobo ezahlukene zezinto, kufaka phakathi i-PVC, i-CPVC, i-clear, kanye ne-industrial.

Kunezinhlobo ezimbili zama-valve okuhlola ukujiya okufanele sigxile kuzo:

• I-Top Hinged – Kuleli vali lokuhlola ukujika, i-disc ixhunywe engxenyeni engaphakathi ye-valve nge-hinge evumela i-disc ukuthi ivuleke futhi ivale.

• I-Swashplate – Le valve yokuhlola ukujika yaklanywa ngendlela evumela ivalvu ukuthi ivuleke ngokugcwele futhi ivale ngokushesha lapho kucindezelwa ukugeleza okuphansi. Lokhu ikwenza kusetshenziswa idiski enesipilingi enesibuko sedome ukuvumela ivalvu ukuthi ivale ngokushesha kunevalvu enezihibe eziphezulu. Ngaphezu kwalokho, idiski ekule valve yokuhlola iyantanta, ngakho uketshezi lugeleza phezulu nangaphansi kobuso bediski.
Lezi zinhlobo zama-check valve zivame ukusetshenziswa ukuvimbela ukukhukhuleka kwendle kanye nezinhlelo zokuvikela umlilo. Zisetshenziswa ezinhlelweni ezihambisa uketshezi, amagesi kanye nezinye izinhlobo zezinto ezisetshenziswayo.

Iliftiivalvu yokuhlola
Amavalvu okuhlola ukuphakama afana kakhulu namavalvu omhlaba. Asebenzisa ama-piston noma amabhola esikhundleni samadiski asetshenziswa amavalvu okuhlola okujikelezayo. Amavalvu okuhlola ukuphakama asebenza kahle kakhulu ekuvimbeleni ukuvuza kunamavalvu okuhlola okujikijelayo. Ake sibheke lawa mavalvu amabili okuhlola ukuphakama:

• I-Piston – Lolu hlobo lwe-check valve lwaziwa nangokuthi i-plug check valve. Lulawula ukuhamba koketshezi ezinhlelweni zamapayipi ngokuhamba okuqondile kwe-piston ngaphakathi kwegumbi le-valve. Ngezinye izikhathi i-piston inesipilingi esinamathiselwe, esisiza ukuthi ihlale ivaliwe uma ingasetshenziswa.

I-PVC Ball Check Ball Valve Ecacile • I-Ball Valve – I-Ball check valve isebenza kalula ngokusebenzisa amandla adonsela phansi. Uma kunokucindezela okwanele kuketshezi, ibhola liyaphakanyiswa, futhi uma ingcindezi incishisiwe, ibhola liyagoqeka phansi bese livala indawo evulekile. Ama-Ball check valve atholakala ngezinhlobo ezahlukene zezinto zokwakha kanye nezinhlobo zesitayela: I-PVC: ecacile nempunga, i-CPVC: i-true joint kanye ne-compact.

Iliftiama-valve okuhlolaZisetshenziswa ezindaweni eziningi zokusebenza ezimbonini eziningi. Uzothola ezindaweni zokuhlala nezimboni. Zisetshenziswa embonini yokudla neziphuzo, embonini kawoyela negesi, kanye nasembonini yasolwandle, ukubala ezimbalwa.

I-valve yokuhlola ubhathane
I-valve yokuhlola i-butterfly ihlukile ngoba i-disc yayo iyagoqeka phakathi ukuze kuvunyelwe uketshezi ukuthi lugeleze. Uma ukugeleza kuguqulwa, izingxenye ezimbili ziyavuleka futhi ukuze kuvalwe i-valve evaliwe. Le valve yokuhlola, eyaziwa nangokuthi i-double plate check valve noma i-folding disc check valve, ifaneleka ezinhlelweni zoketshezi olunomfutho ophansi kanye nezinhlelo zamapayipi egesi.

I-valve yokuhlola i-globe
Amavalvu okuhlola okuvala akuvumela ukuthi uqale futhi umise ukugeleza ohlelweni lwamapayipi. Ahlukile ngoba akuvumela nokuthi ulawule ithrafikhi. Ivalvu yokuhlola imbulunga ngokuyisisekelo iyivalvu yokuhlola enokulawula kokudlula okumisa ukugeleza kungakhathalekile ukuthi ukugeleza kuqondiswe kuphi noma ingcindezi. Uma ingcindezi iphansi kakhulu, ivalvu yokuhlola ivala ngokuzenzakalelayo ukuze ivimbele ukugeleza emuva. Lolu hlobo lwevalvu yokuhlola lungasebenza ngokusebenzisa ukulawula kwangaphandle kunesilawuli sokudlula, okusho ukuthi ungafaka ivalvu endaweni evaliwe kungakhathalekile ukuthi ukugeleza kunjani.

Ama-valve okuhlola i-globe asetshenziswa kakhulu ezinhlelweni zama-boiler, ezitshalweni zikagesi, ekukhiqizweni kukawoyela kanye nasezinhlelweni zokuphepha ezicindezela kakhulu.

Imicabango Yokugcina Ngama-Check Valve
Uma kukhulunywa ngokuvimbela ukugeleza kwamanzi emuva, ayikho enye indlela ngaphandle kwe-check valve. Manje njengoba usuyazi kancane ngezinhlobo ezahlukene zama-check valve, kufanele ukwazi ukunquma ukuthi iyiphi engcono kakhulu kuhlelo lwakho lokusebenza.
