Amavaluvu angamadivayisi awusizo asiza ukulawula, ukukhawulela, nokuvala ukugeleza kusistimu. Ensimini yokuchelela engadini, ungasebenzisa amavalvu ukulawula lapho izitshalo ezahlukene ziniselwa. Nakuba ama-valve ngokuvamile ebhekwa njengewusizo, ukukhetha i-valve efanele kungakhungathekisa. Sizwa kumakhasimende amaningi: “Izinhlobo eziningi kakhulu! Abanye benza into enjalo! Angazi ukuthi hlobo luni lwevalvu okumele lusetshenziswe!”

Ungakhathazeki! Kwa-PVC Fittings Online sinikeza zonke izinhlobo ezinkulu zama-valve. Kulokhu okuthunyelwe kwebhulogi, sizochaza ukuthi yini eyenza ngayinye ihluke. Kubasebenzisi abayisisekelo, into ebaluleke kakhulu okufanele uyikhumbule ukuthi i-valve ingenza enye yezinto ezimbili: ukuvala noma ukulawula.

Kunembobo maphakathi nebhola ukuze uketshezi lukwazi ukudlula lapho isibambo sijikijelwa endaweni "esivuliwe". Uma isibambo sizungeziswe ngamadigri angu-90 ukuya endaweni “yokucisha,” uketshezi lushaya uhlangothi oluqinile lwebhola bese luyama.

I-valve yebhola ye-PVC esesithombeni ihlakaziwe ukuze ukwazi ukubona ukusebenza kwayo kwangaphakathi. Lona usebenzisa i-O-ring yerabha ukuqinisekisa uphawu.

Ukugeleza ngokuvula okuncane kuzovinjelwa, kunciphisa ukucindezela phansi kwepayipi, kuye ngokuthi i-valve ivuleke kangakanani. Amavalvu ovemvane angasetshenziswa futhi njengamavalves ajikelezayo ajwayelekile angu-90 ngokumane ashintshe phakathi kwezindawo “zokuvula” kanye “nokuvala”.

Ama-valve ovemvane asebenzisa i-disc ezungeza isiqu esimaphakathi ukulawula ukudlula koketshezi. Ivalve uvemvane we-PVC osesithombeni inesibambo esima futhi sikhiye noma yikuphi phakathi kokuvuleka noma ukuvaleka ngokugcwele. Lokhu kuvumela ukulawula okunembayo. Isici esiyinhloko okufanele usiqaphele lapho usebenzisa ama-valve ovemvane ukuthi adinga ama-flange akhuphukayo. Awukwazi ukumane uwaxhume kumapayipi. Lokhu kwenza ukufaka kube nzima kakhulu, kodwa kungenzeki! Esinye isici esibalulekile se-butterfly valves ukuthi kukhona ukwehla kwengcindezi engokwemvelo ngoba i-disc ihlale igeleza.

Ngokungafani nama-valve amabili okuqala, i-valve yesango ayiyona i-valve-turn valve. Basebenzisa isondo lesandla ukuvula/ukuvala, kuyilapho amavalvu ebhola nawevemvane esebenzisa isibambo se-lever. Lokhu kuzenza kube lula ukuzigcina zivulekile kancane futhi kwenza noma yiluphi uhlobo lokukhohlisa lube lula.

Enye indlela yokusebenzisa i-valve yesango yokulawula ukugeleza ukuthi uketshezi luzoshaya indawo yesango eliyisicaba. Ngokuya ngenani lokucindezela ohlelweni, lokhu kungabangela ukuguga ngokuhamba kwesikhathi. Ivalvu yesango esesithombeni iwumklamo wenyunyana wangempela, okusho ukuthi ingahlakazwa kalula.

Ama-valve okuhlola eza ngezindlela eziningi ezahlukene, kodwa sizovala kuphela izinhlobo ezimbili ezivame kakhulu.

I-valve yokuhlola i-swing iyi-valve esebenzisa umsebenzi wokushwiba ukuvimbela ukubuyela emuva ohlelweni. I-valve yokuhlola ukujika kwe-PVC ecacile kwesokudla inediski ekhumula uma uketshezi ludlula ngendlela oyifunayo. Uma kukhona okuzama ukubuyisela emuva ukugeleza, i-disc iphushwa ivaliwe, imise ukugeleza.
