Ivalvu sisixhobo esilawula ukuhamba kombhobho kwaye siyinxalenye ephambili yobunjineli bemibhobho kwiindawo ezahlukeneyo. Ivalvu nganye ifuna indlela yokuvulwa (okanye ukuqaliswa kwayo). Kukho iintlobo ezininzi ezahlukeneyo zeendlela zokuvula ezikhoyo, kodwa ezona zixhobo ziqhelekileyo zokuqalisa iivalvu eziyi-14″ nangaphantsi ziigiya kunye nee-levers. Ezi zixhobo zisebenza ngesandla azibizi kakhulu kwaye kulula ukuzisebenzisa. Kwakhona, azidingi naluphi na ucwangciso olongezelelweyo okanye zilula kakhulu. Ukufakela (esi sithuba singena kwiinkcukacha zokusebenza kwegiya ngokweenkcukacha) Esi sithuba sebhlog sinika umbono osisiseko weevalvu ezisebenza ngegiya kunye neevalvu ezisebenza nge-lever.

ivalvu esebenzisa igiya
Ivalvu esebenza ngegiya yeyona inzima kakhulu kubaqhubi ababini abasebenza ngesandla. Ngokuqhelekileyo zifuna umgudu ongakumbi ukufaka nokusebenza kunevalvu esebenza nge-lever. Uninzi lweevalvu ezisebenza ngegiya zinegiya ze-worm ezenza kube lula ukuzivula nokuzivala. Oku kuthetha ukuba uninziiivalvu ezisebenzisa igiyakufuneka ujike izihlandlo ezimbalwa ukuze uvule okanye uvale ngokupheleleyo. Iivalvu ezisebenzisa igiya zihlala zisetyenziswa kwiimeko zoxinzelelo olukhulu.

Uninzi lwezixhobo zegiya zenziwe ngentsimbi ukuqinisekisa ukuba ziyakwazi ukumelana nobunzima kwaye ziqhubeke nokusebenza. Nangona kunjalo, ukuqina kwevalvu esebenza ngegiya akulula. Iigiya zibiza kakhulu kunee-levers, kwaye kunzima ukuzifumana ngee-valve ezincinci. Kwakhona, inani lezixhobo ezikhoyo kwigiya lenza into ingasebenzi kakuhle.

Iivalvu ezisebenza nge-lever kulula ukuzisebenzisa kuneevalvu ezisebenza ngegiya. Ezi ziivalvu ezijika ngekota, oko kuthetha ukuba ukujika nge-90-degree kuya kuyivula okanye kuyivala ngokupheleleyo ivalvu.uhlobo lwevalvu, i-lever inamathele kwintonga yesinyithi evula kwaye ivale ivalvu.

Enye inzuzo yeevalvu ezisebenza nge-lever kukuba ezinye zazo zivumela ukuvulwa nokuvalwa okungaphelelanga. Ezi zitshixa naphi na apho intshukumo yokujikeleza iyema khona. Olu phawu luluncedo kwiiprojekthi ezifuna umlinganiselo ochanekileyo. Nangona kunjalo, njengeevalvu ezisebenza ngegiya, iivalvu ezisebenza nge-lever zineengxaki. Iilevera zithatha indawo engaphezulu kuneevalvu kwaye ngokubanzi azikwazi ukumelana noxinzelelo olufana nolweegiya kwaye ngenxa yoko zisengozini yokuqhekeka. Kwakhona, iilevera zinokufuna amandla amaninzi ukuze zisebenze, ingakumbi kwiiivalvu ezinkulu.

Iivalvu Ezisebenzisa Iigiya Xa Zithelekiswa Neevalvu Ezisebenzisa IiLever
Xa kufikwa kumbuzo wokuba kusetyenziswe i-lever okanye igiya na ukusebenzisa ivalvu, akukho mpendulo icacileyo. Njengakwizixhobo ezininzi, konke kuxhomekeke kwinto efunekayo kumsebenzi okhoyo. Iivalvu ezisebenzisa iigiya zinamandla kwaye zithatha indawo encinci. Nangona kunjalo, ngokubanzi zibiza kakhulu kwaye zineendawo ezininzi ezisebenzayo ezinokungaphumeleli. Iivalvu ezisebenzisa iigiya zikwafumaneka ngobukhulu obukhulu kuphela.

Iivalvu ezisebenzisa i-lever zibiza kancinci kwaye kulula ukuzisebenzisa. Nangona kunjalo, zithatha indawo engakumbi kwaye kunzima ukuzisebenzisa kwiivalvu ezinkulu. Nokuba ukhetha luphi uhlobo lwevalvu, qiniseka ukuba ujonge ukhetho lwethu lweevalvu ezisebenzisa i-PVC gear kunye ne-PVC lever!
