Amavalvu e-Newsway Valve Company (NSW) asetshenziswa kabanzi emikhakheni eyahlukene yamapayipi, angahlangabezana nalezi zidingo ezilandelayo amapayipi amapayipi

1. Sika bese ukhulula okuphakathi

Lona umsebenzi oyisisekelo kakhulu we-valve. Ngokuvamile, i-valve enendlela yokugeleza eqondile ikhethiwe, futhi ukumelana kwayo kokugeleza kuncane.

Ama-valve avalwe ngezansi (Ama-valve e-globe, ama-plunger valves) awavamile ukusetshenziswa ngenxa yokugeleza kwawo okuhlukumezayo kanye nokumelana nokugeleza okuphezulu kunamanye ama-valve. Lapho ukumelana nokugeleza okuphezulu kuvunyelwe, i-valve evaliwe ingasetshenziswa.

2. Cukugeleza kokulawula

Ngokuvamile, i-valve elula ukulungisa ukugeleza ikhethwa njengokulawula ukugeleza. I-valve yokuvala eyehlayo (njenge-ai-valve yomhlaba) ifanele le njongo ngoba usayizi wesihlalo sayo ulingana nokushaya kwelungu elivalayo.

Ama-valve ajikelezayo (Ama-valve wokuxhuma, izivalo uvemvane, ama-valve ebhola) nama-flex-body valves (ama-valve ama-pinch, ama-diaphragm valves) nawo angasetshenziselwa ukulawula ukudonsa, kodwa ngokuvamile asebenza kuphela phakathi kwebanga elilinganiselwe lamadiamitha ama-valve.

I-valve yesango isebenzisa isango elimise okwe-disc ukwenza umnyakazo wokunqamula endaweni yokuvula isihlalo se-valve esiyindilinga. Ingakwazi ukulawula ukugeleza kahle kuphela uma iseduze nendawo evaliwe, ngakho ngokuvamile ayisetshenziselwa ukulawula ukugeleza.

3. Ukuhlehla nokunyakazisa

Ngokwezidingo zokuhlehla kanye nokushunqa, lolu hlobo lwevalvu lungaba namashaneli amathathu noma ngaphezulu. Ama-valve wokuxhuma futhiAma-valve amabhola angu-3zilungele le nhloso. Ngakho-ke, ama-valve amaningi asetshenziselwa ukuhlehlisa nokuhlukanisa ukugeleza akhetha eyodwa yalawa ma-valve.

Kodwa kwezinye izimo, ezinye izinhlobo zama-valve nazo zingasetshenziselwa ukuhlehla nokushunqa inqobo nje uma ama-valve amabili noma ngaphezulu exhumeke kahle komunye nomunye.

4. Phakathi nezinhlayiya ezimisiwe

Uma kunezinhlayiya ezimisiwe phakathi nendawo, kufaneleka kakhulu ukusebenzisa i-valve enomthelela wokusula ekusheleleni kwelungu elivala eduze kwendawo yokuvala.

Uma ukunyakaza emuva naphambili kwelungu elivalayo esihlalweni se-valve kumi mpo, kungase kubambe izinhlayiya. Ngakho-ke, le valve ifaneleka kuphela imidiya ehlanzekile eyisisekelo ngaphandle uma impahla yokuvala ivumela izinhlayiya ukuthi zishumekwe. Ama-valve ebhola nama-plug valve anomphumela wokusula endaweni yokuvala ngesikhathi sokuvula nokuvala, ngakho afaneleka ukusetshenziswa kumidiya enezinhlayiya ezimisiwe.
