Iivalvu zebhabhathane zizivalo zekota ezisetyenziselwa ukulawula ukuhamba kwamanzi. Idiski yentsimbi kwiivalveumzimba perpendicular kulwelo kwindawo evaliweyo kwaye ijikeleziswa ikota jiko ukuba parallel kulwelo kwindawo evuleke ngokupheleleyo. Ukujikeleza okuphakathi kuvumela ukulungiswa kokuhamba kolwelo. Ngokuqhelekileyo zisetyenziswa kwezolimo kunye namanzi okanye izicelo zokucocwa kwamanzi amdaka kwaye yenye yezona ntlobo zixhaphakileyo kwaye zaziwa kakhulu zeevalvu.

Iinzuzo zeivelufa butterfly
Iivalve zebhabhathane ziyafana neevalvu zebhola, kodwa zineengenelo ezininzi. Zincinci kwaye, xa zisebenza nge-pneumatic, zinokuvula kwaye zivale ngokukhawuleza. I-disc ilula kunebhola, kwaye i-valve idinga ukuxhaswa kwesakhiwo esincinci kune-valve yebhola elinganayo. Iivalve zebhabhathane zichaneke kakhulu, nto leyo ibanika inzuzo kwizicelo zoshishino. Zithembeke kakhulu kwaye zifuna ukugcinwa okuncinci.

Ukungalungi kwevalve yebhabhathane
Enye into engalunganga yeevalve zebhabhathane kukuba enye inxalenye yediski ihlala ikhona ekuhambeni, nangona ivuleke ngokupheleleyo. Ngoko ke, ukusebenzisa i-valve ye-butterfly iya kuhlala idala ukutshintshwa koxinzelelo kwi-valve, kungakhathaliseki ukuba isethingi.

Iivalvu zebhabhathane zoMbane, zePeneumatic okanye ngesandla

Iivalve zebhabhathaneinokuthi iqwalaselwe kwi-manual, i-electric okanye i-pneumatic operation. Iivalve zepneumatic zisebenza ngokukhawuleza. Iivalvu ze-elektroniki kufuneka zithumele umqondiso kwibhokisi yegiya ukuze uvule okanye uvale, ngelixa iivalve zepneumatic zinokusebenza-nye okanye zisebenze kabini. Iivalvu ezisebenza-nye ziqhele ukusetwa ukuze zifune umqondiso wokuvula nge-failsafe, okuthetha ukuba xa amandla elahlekile, ivalve ibuyela kwindawo evalwe ngokupheleleyo. Iivalve zepneumatic ezisebenza kabini azilayishwanga entwasahlobo kwaye zifuna uphawu lokuvula nokuvala.

Iivalve zebhabhathane zepneumatic ezizenzekelayo zithembekile kwaye zomelele. Ukunciphisa ukuguga kuphucula umjikelo wobomi bevalvu, ngokwenjenjalo kuncitshiswa iindleko zokusebenza ebeziya kulahleka kwiiyure zokusebenza kugcino lwevalvu.
