I-valve imibuzo evame ukubuzwa 9 imibuzo 9 izimpendulo
1. Kungani i-valve yezihlalo ezimbili kulula ukuyishintsha lapho isebenza ngokuvula okuncane?i
Ngomgogodla owodwa, lapho okuphakathi kuwuhlobo oluvulekile lokugeleza, ukuzinza kwe-valve kuhle;lapho i-medium iwuhlobo lwe-flow-close, ukuzinza kwe-valve kubi.I-valve enezihlalo ezimbili inama-spool amabili, i-spool engezansi ivaliwe futhi i-spool ephezulu ivuliwe.Ngale ndlela, lapho usebenza ekuvuleni okuncane, i-spool evaliwe ngokugeleza izobangela kalula ukuthi i-valve idlidlize.Lona i-valve enezihlalo ezimbili.Isizathu sokuthi kungani ingakwazi ukusetshenziselwa umsebenzi wokuvula omncane.
2. Kungani ivalvu evala uphawu kabili ingasetshenziswa njengevalvu yokuvala?i
Inzuzo yomgogodla we-valve enezihlalo ezimbili yisakhiwo sebhalansi yamandla, okuvumela umehluko omkhulu wengcindezi, kodwa ukonakala kwayo okuvelele ukuthi izindawo ezimbili zokuvala azikwazi ukuxhumana kahle ngesikhathi esisodwa, okuholela ekuvuzeni okukhulu.Uma isetshenziswa ngokungemthetho futhi ngenkani ezikhathini zokunqunywa, umphumela ngokusobala awumuhle, noma ngabe ukuthuthukiswa okuningi (njengama-valve emikhono evalwe kabili) kwenziwe ngakho, akukhuthazwa.
3. Iyiphi i-valve elawula ukushaywa kwe-straight enokusebenza okungekuhle kwe-anti-blocking, kanti i-quarter-stroke valve inokusebenza okuhle kokuvimba ukuvinjwa?i
I-spool yevalvu ye-straight-stroke impintsha iqonde phezulu, kuyilapho i-medium igeleza iphinde iphume ivundlile.Umzila wokugeleza emgodini wevalvu kufanele ujike uphinde ubuyele emuva, okwenza indlela yokugeleza kwevalvu ibe nzima kakhulu (umumo ufana nomumo othi "S" ohlanekezelwe).Ngale ndlela, kunezindawo eziningi ezifile, ezihlinzeka ngendawo yokuna kwe-medium, futhi uma izinto ziqhubeka kanje, kuzodala ukuvinjelwa.I-throttling ye-valve ye-quarter-turn isiqondiso esivundlile.I-medium igeleza ivundlile futhi igeleze iphumele ngokuvundlile.Kulula ukususa i-medium engcolile.Ngesikhathi esifanayo, indlela yokugeleza ilula futhi kunesikhala esincane sokuhlala okuphakathi, ngakho-ke i-valve ye-quarter-turn valve inokusebenza okuhle kokuvimbela ukuvimbela.
4. Kungani isiqu se-valve ye-valve elawula i-stroke incane?i
Kuhilela umgomo olula womshini: uma kukhulu ukushwibilika kwamaslayidi, kuyancipha ukushwibeka.Isiqu se-valve ye-stroke eqondile siya phezulu naphansi.Uma ukugxusha kucindezelwa kancane, bekuyosonga isiqu ngokuqinile, okuholela ekubambeni okukhulu kwe-hysteresis.Kuze kube manje, isiqu se-valve yakhelwe ukuba ibe mncane futhi ibe mncane futhi ukugxusha kusebenzisa i-PTFE ene-coefficient encane yokungqubuzana ukuze kwehliswe i-hysteresis.Kodwa inkinga etholakala kulokhu ukuthi i-valve stem encane kulula ukugoba futhi ukugxusha kunokuphila okufushane kwenkonzo.Ukuxazulula le nkinga, indlela engcono kakhulu ukusebenzisa isiqu se-valve ejikelezayo, i-valve elawulayo efana ne-rotary stroke.Isiqu se-valve saso siwugqinsi izikhathi ezi-2 kuya kwezi-3 kunaleso se-valve ye-stroke eqondile, futhi ukupakishwa kwe-graphite ngempilo ende yesevisi kusetshenziselwa ukuthuthukisa ukuqina kwesiqu se-valve.Yebo, ukupakishwa kunempilo ende yesevisi, kodwa i-torque yayo yokungqubuzana incane futhi i-hysteresis incane.
5. Kungani umehluko we-cut-off pressure yamavalvu wekota-turn mkhulu?i
Amavalvu e-quarter-turn anomehluko omkhulu wengcindezi enqamuliwe ngenxa yokuthi amandla angumphumela akhiqizwa i-medium kumongo we-valve noma ipuleti le-valve akhiqiza isikhashana esincane kakhulu ku-shaft ejikelezayo, ngakho angakwazi ukumelana nomehluko omkhulu wengcindezi.
6. Kungani amavalvu evemvane anemigqa yeraba kanye namavalvu e-diaphragm ane-fluorine enomugqa omncane wesevisi wamanzi akhishwe usawoti?i
Indawo yamanzi ekhishwe usawoti iqukethe ukugxila okuphansi kwe-asidi noma i-alkali, edla kakhulu irabha.Ukubola kwerabha kubonakala njengokunwetshwa, ukuguga, namandla aphansi.Amavalvu ovemvane namavalvu e-diaphragm anenjoloba awasebenzi kahle.Ingqikithi iwukuthi irabha ayimelani nokugqwala.I-valve ye-diaphragm enerabha yangemuva yathuthukiswa yaba yivalve ene-fluorine diaphragm ekwazi ukumelana nokugqwala, kodwa i-diaphragm ye-diaphragm ene-fluorine-lined valve ayikwazanga ukumelana nokugoqeka phezulu naphansi futhi yaphuka, yadala ukulimala kwemishini futhi yanciphisa impilo ye-diaphragm. i-valve.Indlela engcono kakhulu manje ukusebenzisa i-valve yebhola ekhethekile yokwelapha amanzi, engasetshenziswa iminyaka engu-5-8.
7. Kungani i-valve yokusika kufanele ivalwe ngokuqinile ngangokunokwenzeka?i
I-valve yokusika idinga ukuvuza okuphansi, okungcono.Ukuvuza kwevalvu evalwe ngokuthambile kuphansi kakhulu.Yebo, umphumela wokusika muhle, kodwa awukwazi ukumelana nokugqoka futhi unokwethenjelwa okubi.Uma sibheka izindinganiso eziphindwe kabili zokuvuza okuncane nokuvaleka okuthembekile, ukunqanyulwa kwezivalo ezithambile akukuhle njengokusikwa kophawu oluqinile.Isibonelo, i-valve elawula ukukhanya kwe-ultra-light egcwele ngokugcwele ivalwe futhi ivikelwe ngama-alloy angagugi, enokwethenjelwa okuphezulu kanye nezinga lokuvuza lika-10-7, elingavele lihlangabezane nezidingo zama-valve avaliwe.
8. Kungani ama-sleeve valves athatha indawo yesihlalo esisodwa nesesihlalo esikabili ahluleka?i
Amavalve emikhono, aphuma ngeminyaka yawo-1960, ayesetshenziswa kakhulu ekhaya naphesheya ngeminyaka yawo-1970.Amavalvu emikhono abala ingxenye enkulu yezitshalo ze-petrochemical ezethulwa ngawo-1980.Ngaleso sikhathi, abantu abaningi babekholelwa ukuthi ama-sleeve valves angashintsha ama-valve angashadile namabili.I-valve yesihlalo yaba umkhiqizo wesizukulwane sesibili.Namuhla, akunjalo, ama-valve anesihlalo esisodwa, ama-valve anezihlalo ezimbili, nama-sleeve valves asetshenziswa ngokulinganayo.Lokhu kungenxa yokuthi i-valve ye-sleeve ithuthukisa kuphela ifomu le-throttling, futhi ukuzinza nokugcinwa kwayo kungcono kune-valve yesihlalo esisodwa, kodwa isisindo sayo, izinkomba ezivimbela ukuvinjelwa kanye nokuvuza zihambisana ne-valve yesihlalo esisodwa kanye nesikabili.Ingawashintsha kanjani ama-valve anesihlalo esisodwa nesikabili?Indwangu yewuli?Ngakho-ke, ingasetshenziswa kuphela ndawonye.
9. Kungani ukukhetha imodeli kubaluleke ngaphezu kokubala?i
Uma kuqhathaniswa nokubala nokukhetha, ukukhetha kubaluleke kakhulu futhi kuyinkimbinkimbi kakhulu.Ngenxa yokuthi ukubala kumane kuyisibalo sefomula elula, akukholi ekunembeni kwefomula ngokwayo, kodwa ekutheni imingcele yenqubo enikeziwe inembile yini.Ukukhethwa kwemodeli kuhilela okuqukethwe okuningi, futhi ukunganaki okuncane kuzoholela ekukhethweni okungalungile, okungeke kubangele ukuchithwa kwabasebenzi, izinsiza ezibonakalayo, kanye nemithombo yezezimali, kodwa futhi kubangele imiphumela engagculisi yokusetshenziswa, okuzoletha izinkinga ezithile ezisetshenziswayo, ezifana. njengokwethenjelwa, impilo, izinga lokusebenza njll.
