Ivalve sisixhobo esilawula ukuhamba kombhobho kwaye iyona nto iphambili yobunjineli bombhobho kwiindawo ezahlukeneyo.Ivalve nganye idinga indlela enokuvulwa ngayo (okanye isebenze).Kukho iintlobo ezininzi ezahlukeneyo zeendlela zokuvula ezikhoyo, kodwa ezona zixhobo zixhaphakileyo zokuvula iivalvu 14″ nangaphantsi ziigiya kunye nezixhobo.Ezi zixhobo zisebenza ngesandla azibizi kwaye kulula ukuziphumeza.Kwakhona, abafuni naluphi na ucwangciso olongezelelweyo okanye ngaphezu kokulula Ufakelo (esi sithuba singena kwiinkcukacha zokusebenza kweegiya kwiinkcukacha ezithe vetshe) Esi sithuba seblogi sinikeza inkcazo esisiseko yee-valve ezisebenzayo kunye ne-lever esebenzayo.

ivalve esebenzayo
Ivalve esebenza ngegiya yeyona nto intsonkothe ​​ngakumbi kubasebenzisi ababini bezandla.Ngokuqhelekileyo zifuna umzamo omkhulu wokufaka nokusebenza kuneevalve ezisebenza nge-lever.Uninzi lweevalvu ezisebenza ngegiya zinezixhobo zeentshulube ezenza kube lula ukuzivula nokuvala.Oku kuthetha ukuba uninziiivalve ezisebenza ngegiyakufuneka kuphela amaxesha ambalwa ukuvula okanye ukuvala ngokupheleleyo.Iivalvu ezisebenza ngegiya zidla ngokusetyenziswa kwiimeko zoxinzelelo oluphezulu.

Uninzi lwezixhobo zegiya zenziwe ngesinyithi ngokupheleleyo ukuqinisekisa ukuba zinokubetha kwaye zisasebenza.Nangona kunjalo, ukomelela kwevalve esebenza ngegiya ayikuko konke ukuhamba ngesikhephe.Iigiya zisoloko zibiza kakhulu kuneentsimbi, kwaye kunzima ukuzifumana ngeevalvu ezinobungakanani obuncinci.Kwakhona, inani lamalungu akhoyo kwigiya lenza into enokwenzeka ukuba ingaphumeleli.

ivalve esebenzayo ye-lever
ivalve esebenzayo ye-lever

Iivalvu ezisebenza nge-lever kulula ukusebenza kuneevalve ezisebenza ngegiya.Ezi zivalo zekota, oku kuthetha ukuba ukujika kwe-90-degree kuya kuvula ngokupheleleyo okanye ukuvala ivalve.Nokuba yintoni nauhlobo lwevalvu, i-lever ifakwe kwintonga yentsimbi evula kwaye ivale i-valve.

Olunye uncedo lweevalvu ezisebenza nge-lever kukuba ezinye zazo zivumela ukuvulwa kunye nokuvala inxalenye.Ezi zitshixa naphi na apho intshukumo yokujikeleza iyeka khona.Olu phawu luluncedo kwiiprojekthi ezifuna imilinganiselo echanekileyo.Nangona kunjalo, njengeevalve ezisebenza ngegiya, iivalve ezisebenza nge-lever zinemiqobo.Ii-leverages zithatha indawo eninzi kuneevalvu kwaye ngokubanzi azikwazi ukumelana noxinzelelo oluninzi njengeegiya kwaye ke ngoko ziqhelene kakhulu nokwaphuka.Kwakhona, iilevers zinokufuna amandla amaninzi ukuze zisebenze, ngakumbi kwiiivalve ezinkulu.

Iivalvu eziSebenzisiweyo zeGear vs
Xa kuziwa kumbuzo wokuba usebenzise i-lever okanye i-gear ukuze usebenzise i-valve, akukho mpendulo ecacileyo.Njengakwizixhobo ezininzi, konke kuxhomekeke ekubeni ubandakanya ntoni na umsebenzi okhoyo.Iivalvu ezisebenza ngegiya zomelele kwaye zithatha indawo encinci.Nangona kunjalo, zibiza kakhulu kwaye zineendawo ezininzi ezisebenzayo ezinokungaphumeleli.Iivalvu ezisebenza ngegiya zikwafumaneka kuphela ngobukhulu obukhulu.

Iivalvu ezisebenza ngeLever zitshiphu kwaye kulula ukuzisebenzisa.Nangona kunjalo, zithatha indawo eninzi kwaye kunzima ukusebenza kwiivalvu ezinkulu.Kungakhathaliseki ukuba yiyiphi ivalve oyikhethayo, qiniseka ukuba uhlolisise ukhetho lwethu lwe-PVC esebenza ngegiya kunye ne-PVC esebenza nge-lever!
