Izikhathi ezisebenzayo ze-butterfly valve

Amavalvu ebhabhathane zifanele amapayipi athutha izinto ezahlukahlukene ezibangela ukubola kanye nokungaboli ezinhlelweni zobunjiniyela njengegesi yamalahle, igesi yemvelo, igesi kaphethiloli encibilikisiwe, igesi yedolobha, umoya oshisayo nobandayo, ukuncibilikisa amakhemikhali, ukukhiqizwa kukagesi kanye nokuvikelwa kwemvelo, futhi asetshenziselwa ukulungisa nokunqamula ukuhamba kwezinto ezibangela ukubola.

Amavalvu ebhabhathane zifanele ukulawulwa kokugeleza. Ngenxa yokuthi ukulahlekelwa yingcindezi yevalvu yebhabhathane epayipini kukhulu kakhulu, cishe ngokuphindwe kathathu kunevalvu yesango, lapho kukhethwa ivalvu yebhabhathane, ithonya lesistimu yepayipi ngokulahlekelwa yingcindezi kufanele licatshangelwe ngokugcwele, futhi ukuqina kwepuleti lebhabhathane ukumelana nengcindezi yepayipi kufanele kucatshangelwe uma livaliwe. Ngaphezu kwalokho, imikhawulo yokushisa yokusebenza kwezinto zesihlalo se-elastomeric emazingeni okushisa aphezulu nayo kumele icatshangelwe.

Ubude besakhiwo kanye nokuphakama okuphelele kwesakhiwoivalvu yebhabhathanezincane, isivinini sokuvula nokuvala siyashesha, futhi zinezici ezinhle zokulawula uketshezi. Umgomo wesakhiwo sevalvu yovemvane ufaneleka kakhulu ekwenzeni amavalvu anobubanzi obukhulu. Umaivalvu yebhabhathane iyadingeka ukuze isetshenziswe ukulawula ukugeleza kwamanzi, into ebaluleke kakhulu ukukhetha kahle usayizi nohlobo lwevalvu yebhabhathane ukuze isebenze kahle nangendlela efanele.

Ngokuvamile, ekucindezelweni, kudingeka ukulawula okulawulayo kanye nodaka oluphakathi nendawo, ubude besakhiwo obufushane kanye nesivinini sokuvula nokuvala okusheshayo (1/4r). Kunconywa ukusika ingcindezi ephansi (ingcindezi encane yomehluko), i-butterfly valve.I-valve yebhabhathaneingasetshenziswa ekulungiseni izikhundla ezimbili, isiteshi esincishisiwe, umsindo ophansi, ukubhoboza kanye nokufaka igesi, ukuvuza okuncane emoyeni, kanye nendawo yokuhudula.

I-ci-oncentric ivalvu yebhabhathane ifanele amanzi ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, umusi, igesi yemvelo, ukudla, imithi, uwoyela kanye nezinhlobo ezahlukene ze-acid-base kanye neminye imibhobho.

I-valve yebhabhathane ethambile evaliwe kahle ifanelekela ukuvulwa nokuvalwa okunezindlela ezimbili kanye nokulungiswa kwamapayipi okungenisa umoya kanye nokususa uthuli futhi isetshenziswa kabanzi kumapayipi egesi kanye nemizila yamanzi ye-metallurgy, imboni yokukhanya, amandla kagesi, kanye nezinhlelo ze-petrochemical.
