Umgomo wokuklama kanye nokuhlaziywa kwendlela yokusebenza kwamavalvu akhipha anwebekayo akhuphukayo naphansi
Ezinhlelweni zokulawula ezishintshayo zezimboni, ama-valve okukhipha akhuphukayo akhuphukayo adlala indima ebalulekile. Ukwakhiwa kwala ma-valve kuvumela izinto ukuthi zigeleze ngokunembile zingene noma ziphume esitsheni ngaphansi kwezimo ezithile. Lesi sihloko sizohlinzeka ngokuhlaziywa okuningiliziwe kwezimiso zokuklama kanye nezindlela zokusebenza zalawo ma-valve okukhipha.
umgomo wokuklama
Umehluko omkhulu phakathi kwama-valve okukhipha akhuphukayo naphansi yindlela yawo yokuvula. Lapho i-valve yokukhipha okunwetshwayo ivuliwe, i-valve core iya phezulu ukuze ivule isiteshi sokugeleza; I-valve yokukhipha okunwebekayo eyehlayo ifinyelela umphumela ofanayo ngokuhambisa umgogodla we-valve phansi. Lo mklamo uvumela ukuthi zifakwe zingavimbeli phansi noma phezulu kwepayipi.
- Idizayini yesakhiwo: Lezi zinhlobo ezimbili zama-valve ngokuvamile zihlanganisa umzimba we-valve, isembozo se-valve, isihlalo se-valve, kanye ne-valve core. Phakathi kwazo, isihlalo se-valve kanye ne-valve core yizingxenye ezibalulekile zokuqinisekisa ukusebenza kokuvala.
- Indlela yokuvala: Ukuze kuqinisekiswe umphumela wokuvala, amavalvu okukhipha anwebekayo aphezulu naphansi asebenzisa izindawo ezifanayo ezinomshini ezinemba phakathi kwesihlalo se-valve nomongo wevalvu, futhi ngokuvamile zisebenzisa iziphethu zokucindezela nezinye izindlela ukuze zinikeze ingcindezi eyengeziwe ukuze kuthuthukiswe ukuvala.
- Ukukhethwa kwezinto ezibonakalayo: Ngokwezinto ezihlukahlukene zokucubungula, izinto ezihlukahlukene zingakhethwa kumzimba we-valve kanye nomgogodla, njengensimbi engagqwali, i-carbon steel noma ama-alloys akhethekile, kanye nerabha noma i-PTFE (polytetrafluoroethylene) njengezinto zokuvala.
Indlela yokusebenza
- I-valve yokukhipha enwebekayo ephezulu:
-Uma impahla idinga ukukhishwa, sebenzisa amandla esiqwini se-valve ngokusebenzisa ama-hydraulic, pneumatic noma ama-actuator kagesi ukuze uhambise isiqu se-valve futhi umgogodla we-valve ugxile kuso phezulu.
-Phakamisa i-valve core esihlalweni se-valve, vula isiteshi sokugeleza, futhi uvumele okokusebenza ukuthi kugeleze kuphume esitsheni.
-Lapho ukukhishwa sekuqediwe, i-actuator iyakhululeka futhi umgogodla we-valve uphinde ubuyele ngenxa yesisindo sawo noma isiphethu sokuvala esisizayo, ukuvala umzila wokugeleza.
- I-valve yokukhipha enwebekayo ebheke phansi:
-Imodi yokusebenza ye-valve yokukhipha okunwebekayo eyehla ifana naleyo ye-valve enwebekayo eya phezulu, ngaphandle kokuthi umgogodla we-valve uya phansi ukuze uvule umgudu wokugeleza.
-I-actuator iphusha isiqu se-valve nenkaba iye phansi ukuze ivule isiteshi futhi ikhulule i-material.
-Uma ivaliwe, i-valve core iyaphakanyiswa futhi isethwe kabusha ukuze kubuyiselwe isimo sokuvala.
Ukuklanywa kwalawa ma-valve amabili okukhipha kuvumela ukulawulwa kokugeleza okusheshayo nokunembile, okubenza bafaneleke ngokukhethekile izimo ezidinga ukuvulwa nokuvala njalo. Kungakhathaliseki ukuthi ukunwetshwa okuya phezulu noma phansi, ukuklama kwawo ukuqinisekisa ukuthi okokusebenza kungakhishwa ngokushesha futhi ngokuphelele lapho kudingekile, kuyilapho kugcinwa ukusebenza kokuvala okuphezulu kakhulu esimweni esivaliwe.
Kafushane, ama-valve akhipha ukwanda okunwebekayo okukhuphukayo naphansi, ngomklamo wawo oyingqayizivele kanye nesimiso sokusebenza, ahlinzeka ngezixazululo zokulawula eziphumelelayo nezithembekile zezinqubo ezihlukahlukene zezimboni. Lapho abasebenzisi bekhetha ukuyisebenzisa, kufanele bacabangele izidingo ezithile zohlelo lokusebenza, okuhlanganisa izici ezifana nezinga lokugeleza, imvamisa yokusebenza, izakhiwo zentokozo, nezimo zokuyifaka, ukuze kuqinisekiswe ukuthi umphumela ongcono kakhulu wokusebenza uyafinyelelwa. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukuklanywa kanye nokusebenza kwalawa mavalvu okukhipha amanzi nakho kuhlala kuthuthukiswa ukuze kuhlangatshezwane nezidingo eziqinile zohlelo lwezimboni.
