Ivalvu yebhabhathane ephakathi nendawo inesakhiwo esilula futhi kulula ukuyikhiqiza, kodwa ngenxa yesakhiwo sayo kanye nemikhawulo yezinto ezibonakalayo, izimo zokusetshenziswa zilinganiselwe. Ukuze kuhlangatshezwane nezidingo zezimo zokusetshenziswa zangempela, kwenziwe ukuthuthuka okuqhubekayo ngalesi sisekelo, kwabe sekuvela amavalvu ebhabhathane elilodwa elingavamile, amavalvu ebhabhathane amabili angavamile, kanye namavalvu ebhabhathane amathathu angavamile. Isici esikhulu salokhu kungavamile kwesithathu ukuthi kushintsha ngokuyisisekelo isakhiwo sokuvala. Akuseyona uphawu lwendawo, kodwa uphawu lokugoba, okungukuthi, aluncikile ekuguqulweni kwe-elastic kwesihlalo se-valve, kodwa luncike ngokuphelele ekucindezelweni kobuso bokuxhumana kwesihlalo se-valve. Ngakho-ke, umphumela wokuvala uxazulula inkinga yokuvuza okungenalutho kwesihlalo se-valve yensimbi ngesikhathi esisodwa sokuwa, futhi ngenxa yokuthi ingcindezi yobuso bokuxhumana ilingana nengcindezi ephakathi, ingcindezi ephezulu kanye nokumelana nokushisa okuphezulu nakho kuxazululwa kalula.

Izinzuzo zomklamo ophindwe kathathu

1. Umklamo oyingqayizivele we-conical seal uqinisekisa ukuthi idiski ayithinti indawo yokuvala kuze kube yilapho i-valve ivaliwe - lokhu kuholela ekuvalekeni okuphindaphindwayo futhi kwandisa kakhulu impilo ye-valve.

2. Ukuma kwepuleti le-valve ye-valve ye-butterfly eccentric kathathu kuyi-cone eyi-elliptical, futhi ubuso bayo buhlanganiswe nge-alloy eqinile, enokumelana okuhle kakhulu nokuguguleka. Isihlalo sensimbi engagqwali esintantayo esinobunjwa obungu-U sinomsebenzi wokulungisa ngokuzenzakalelayo isikhungo. Lapho i-valve ivulwa, i-disc ye-valve yokunamathisela ubuso be-elliptical cone ihlukaniswa kuqala nesihlalo se-valve elastic esinobunjwa obungu-U, bese ijikeleza; uma ivaliwe, i-valve disc iyajikeleza, bese i-valve disc ilungisa ngokuzenzakalelayo isikhungo nesihlalo se-valve elastic ngaphansi kwesenzo se-shaft eccentric. Isihlalo sisebenzisa ingcindezi yokuguqula isihlalo se-valve kuze kube yilapho isihlalo se-valve kanye ne-elliptical conical sealing surface ye-valve disc ifana kakhulu. Lapho i-valve ivulwa futhi ivaliwe, i-butterfly disc ayiklwebhi isihlalo se-valve, futhi i-torque yesiqu se-valve idluliselwa ngqo endaweni yokuvala ngepuleti le-butterfly, futhi i-torque yokuvula incane, ngaleyo ndlela isuse into evamile yokugxuma lapho kuvulwa i-valve.

3. Ukuvalwa kwensimbi kuya kwensimbi kuqinisekisa ukuthi amabhamuza omoya avaliwe kahle ukuze kufezwe ukusebenza okungenalutho kokuvuza

4. Ifanelekela imidiya eqinile - isakhiwo sensimbi yonke sinikeza ukugqwala nokumelana nokushisa okungenazo ezinye imiklamo yamavalvu ebhabhathane anezimbobo zokunwebeka

5. Ukwakheka kwejometri kwezingxenye zokuvala kunganikeza ukuhamba okungenazingxabano kulo lonke ivalvu. Lokhu kwandisa impilo yevalvu futhi kuvumela ukufakwa kwama-actuator e-torque aphansi.

6. Akukho mgodi phakathi kwezingxenye zokuvala, okungeke kubangele ukuvaleka, kunciphise izindleko zokulungisa futhi kwandise impilo yamavalvu.

7. Ukwakheka kwesihlalo sevalvu kungavimbela ivalvu ukuthi ingashayi kakhulu
