Amavalvu e-Newsway Valve Company (NSW) asetshenziswa kabanzi emikhakheni eyahlukene yamapayipi, angahlangabezana nezidingo ezilandelayoamavalvu epayipi
1. Sika bese ukhulula i-medium
Lona umsebenzi oyisisekelo kakhulu wevalvu. Ngokuvamile, kukhethwa ivalvu enendlela yokugeleza eqondile, futhi ukumelana kwayo nokugeleza kuncane.
Amavalvu avaliwe phansi (Amavalvu embulunga, ama-plunger valve) awavamile ukusetshenziswa ngenxa yezindlela zawo zokugeleza ezigobile kanye nokumelana nokugeleza okuphezulu kunamanye ama-valve. Lapho ukumelana nokugeleza okuphezulu kuvunyelwe khona, i-valve evaliwe ingasetshenziswa.
2. Cukugeleza kokulawula
Ngokuvamile, ivalvu okulula ukuyilungisa igeleza ikhethwa njengokulawula ukugeleza. Ivalvu yokuvala eyehlayo (njenge-ivalvu yomhlaba) ifaneleka kule njongo ngoba ubukhulu besihlalo sayo buhambisana nokushaya kwesitho sokuvala.
Amavalvu ajikelezayo (Amavalvu epulagi, amavalvu ebhabhathane, amavalvu ebhola) kanye nama-valve omzimba okuguquguquka (ama-valve okuncinza, ama-valve e-diaphragm) angasetshenziswa futhi ekulawuleni ukugoqa, kodwa ngokuvamile asebenza kuphela ngaphakathi kobubanzi obulinganiselwe bobubanzi be-valve.
Ivalvu yesango isebenzisa isango elimise okwediski ukwenza ukunyakaza okunqamulayo okuya ekuvulekeni kwesihlalo sevalvu eyindilinga. Ingalawula ukugeleza kahle kuphela uma iseduze nendawo evaliwe, ngakho-ke ngokuvamile ayisetshenziswa ukulawula ukugeleza.
3. Ukubuyela emuva nokushintsha
Ngokuya ngezidingo zokuguqula nokuguqula, lolu hlobo lwevalvu lungaba neziteshi ezintathu noma ngaphezulu. Amavalvu okuxhuma kanyeAmavalvu ebhola anezindlela ezintathuzifaneleka kakhulu kule njongo. Ngakho-ke, iningi lamavalvu asetshenziselwa ukubuyisela emuva nokuhlukanisa ukugeleza likhetha elinye lalawa mavalvu.
Kodwa kwezinye izimo, ezinye izinhlobo zamavalvu zingasetshenziswa futhi ekubuyiseleni emuva nasekushintsheni inqobo nje uma amavalvu amabili noma ngaphezulu exhunywe kahle komunye nomunye.
4. Okuphakathi okunezinhlayiya ezilengayo
Uma kunezinhlayiya ezilengayo endaweni yokuxhumana, kungcono kakhulu ukusebenzisa i-valve enesivikelo sokusula ekusheleleni kwesitho sokuvala endaweni yokuvala.
Uma ukunyakaza kwelungu lokuvala esihlalweni sevalvu kuqondile, kungase kubambe izinhlayiya. Ngakho-ke, leli valve lifanelekela kuphela imidiya ehlanzekile eyisisekelo ngaphandle kokuthi izinto zokuvala zivumela izinhlayiya ukuthi zifakwe. Amavalvu ebhola namavalvu epulaki anomphumela wokusula endaweni yokuvala ngesikhathi senqubo yokuvula nokuvala, ngakho-ke afanele ukusetshenziswa kwimidiya enezinhlayiya ezilengayo.
