Insimbi evaliwe yensimbi yomhlaba
1. Straight ngokusebenzisa imbulunga valve
“Iqonde ngqo” ku-valve yomhlaba eqondile kungenxa yokuthi isiphetho sayo sokuxhuma sise-eksisi, kodwa isiteshi sayo soketshezi empeleni “asiqondile ngqo”, kodwa kunalokho siwubuhlungu. Ukugeleza kufanele kujike ama-90 ° ukudlula esihlalweni bese ubuyela emuva ku-90 ° ukubuyela esiqondisweni saso sokuqala. Kumaphayiphu okusakaza, ukuma kwesiteshi nendawo kuyahluka kuye ngosayizi we-valve nokukala kwengcindezi.
Isakhiwo sesiteshi se-valve esikiwe, noma umzimba womzimba wokukhwabanisa wamahhala uzovame ukungenisa nokuthekelisa imbobo kanye nomugqa ophakathi wepayipi ungene ku-Angle ethile, okuyifomu lesiteshi sokugeleza kwe-Z, futhi okuvame ukucutshungulwa ukunciphisa, noma kunjalo kuncane ukuvula nokugeleza okushisayo kuyokwandisa kakhulu ukulahleka kwengcindezi ketshezi, ngaphezu kwalokho kufanele kuqashelwe ukuthi ukuguqula i-Angle ebucayi esimweni sokusebenza kwento ye-fluid cavitation.
2. I-engela globe valve
Landelela emuva emlandweni wokuthuthukiswa kwe-valve yembulunga, intuthuko yokuqala yi-Angle globe valve, bese kancane kancane yathuthukiswa yaba i-valve yomhlaba eqondile. Yize ama-valve womhlaba oqondile esetshenziswa kakhulu namuhla, ama-valve we-Angle globe asenezinzuzo ezithile ezihlukile.
Ama-valve womhlaba we-Angle avumela ukugeleza ukuze kushintshe izinkomba ezingama-90 futhi njalo kungena kusuka phansi kwesihlalo. Umgijimi uvuleke kakhulu futhi akahlukumezi kangako kune-straight-through, ngakho-ke kuncipha ukulahleka kwengcindezi. Ama-valve we-engela globe awasuswa kalula yizinhlayiya eziqinile. IDiski kungenziwa yakhelwe uzipho noma isiketi ukuma ukulawula kangcono. Ngenxa yokushintsha kokuhamba kokuhamba, umzimba we-valve uzothinteka ngamandla okuphendula oketshezi. Lawa mandla ngokuvamile amancane kodwa angakhuphuka ngenxa yesayizi ye-valve nobuningi bamanzi.
Amaphayiphu omhlaba omncane we-alloy threaded Angle globe valve asetshenziswa kakhulu ezimweni zamanzi ahlanzekile. Iningi lezimboni ze-Angle globe valves luhlobo lwebhonethi eboshwe, elenziwe ngensimbi eyakhiwe, ithusi, insimbi engagqwali, nezinto zensimbi eziyiziduplex.
Ubukhulu obujwayelekile namakilasi okucindezela ama-valve we-Angle globe kuvame ukuba yi-DN50 ~ 250 (NPS2 ~ 10), Class 150 ~ 800. Ngaphandle kwalolu hlu, i-disc elinganiselayo ivame ukusetshenziselwa ukunciphisa ukugxilwa kwe-axial fluid esiqwini.
3, iqonde ukugeleza stop valve
I-valve yeglobhu eqondile yaziwa nangokuthi i-valve efana ne-Y efana ne-valve noma i-oblique globe valve, ingaba yi-valve eqondile ne-Angle maphakathi nesifundazwe. Ukuze ushintshe ishaneli eqondile ye-tortuous fluid, imbobo yesihlalo se-valve kanye nokwakheka komzimba we-valve ku-Angle ethile, ukuze isiteshi sokugeleza siqonde kakhulu nge-eksisi, ukuze kuncishiswe ukulahleka kwengcindezi, ngakho-ke ibizwa ngokuthi " ukugeleza okuqondile ”. Lesi sakhiwo siyathandwa ezinhlelweni eziningi futhi sisetshenziswa kakhulu ezinhlelweni ze-steam. Amandla okuthutha aqinile athuthukiswe kakhulu, kepha ukuhlolwa ngokucophelela kuyadingeka ukuze kusetshenziswe. Straight flow gloves valve futhi inendlela eyodwa yokugeleza. Umgijimi unobubanzi obugcwele nobuncane obuncishisiwe. Ayizifanele izingulube zezingulube ngaphandle kokukhipha ibhonethi.
Idiski imvamisa iyisicaba, iqondiswa ngozipho noma iteyishiwe ukuhlangabezana nezidingo zezimo zokusebenza ezahlukene. Iphrofayili yediski eyakhiwe ingahle yakhiwe ngamathebhu amaningi ukukhiqiza ukuqhuma okuyisisekelo nokwesibili. I-Flat disc ne-claw guide disc valves ingafakwa ukusula ukuhlanza isihlalo ngaphambi kokubekwa uphawu, noma uphawu lwenjoloba lungafakwa esihlalweni ukwenza ngcono ukubekwa uphawu kwe-valve.
Straight flow globe valves imvamisa cast and high pressure valves forged. Ngokuya ngezimo zokusebenza ezihlukile, izinto ezikhethekile ezifana nensimbi engagqwali enezigaba ezimbili zingakhethwa ekukhiqizeni.
4.I-three-way globe valve
Ama-valve amaglobhu endlela amathathu asetshenziswa kakhulu njengama-valve wokuqondisa ezinhlelweni zokucindezela okuphezulu. Isibonelo, izinga lokushisa eliphakeme nokucindezela okuphezulu kokuphakelwa kwamanzi kwama-boilers esiteshini samandla. Ukuya emsebenzini kuvame ukusetshenziswa lapho kuqala, ukuvala, noma ukwehluleka.
Esinye isimo sokusebenza esivame kakhulu njenge-valve yokuguqula uhlelo lokunciphisa ingcindezi. Ama-valve amabili okusiza abekwe ku-valve eyodwa yezindlela ezintathu zomhlaba, evumela ukuthi enye i-valve isebenze ngokujwayelekile lapho enye yazo idinga ukuhlukaniswa noma insizakalo. Ngenxa yesakhiwo sangaphakathi, i-valve yendlela yeglobhu emithathu inokumelana kokugeleza okuphezulu. Ukushintshwa kokuqondiswa koketshezi kuzokhiqiza amandla amakhulu okuphendula kububanzi obukhulu bezindlela ezintathu zomhlaba.
Umzimba wamavalvu we-globe we-tee-way uvame ukwenza insimbi noma i-alloy steel. Amaphayiphu asetshenziswa ezitshalweni zamandla afakwa nge-butt-welded ukunqoba izinkinga zokuvuza ezibangelwa ukuxhumana kwe-flanged.
