Uhlobo lwe-valve yesitshalo sekhemikhali nendawo yokufaka isicelo (ngohlobo olusebenzayo)

Ngemva kokusungulwa kwezinjini ze-steam, eminyakeni engamashumi amabili noma amathathu edlule, ngenxa yesidingo sikawoyela ongahluziwe, izitshalo zamakhemikhali, izimboni zamandla kagesi, imboni yensimbi, imikhumbi, ukukhiqizwa kwamandla enuzi, i-aerospace kanye neminye imikhakha, amalungiselelo angcono abekwe ngokucacile phambili. ama-valve, nama-valve okukhiqiza ezimbonini nawo ahlukene ngezinhlobo.Njenge-valveukwethula indawo yokufaka uhlobo lwevalvu yezitshalo zamakhemikhali kanye nokusebenza ngempumelelo.

Uhlobo lwe-valve yesitshalo samakhemikhali kanye nokusetshenziswa

1. Hlukanisa ngokuya ngokusebenza ngempumelelo kanye nenkambu yohlelo lokusebenza

(1) nqamula ivalvu: ivalvu enqamukile yaziwa nangokuthi i-valve yekhebula yedijithali TELEVISION, futhi umphumela wayo uwukufinyelela noma ukunqamula isisetshenziswa esisepayipini. Ama-valve anqunyiwe ahlanganisa ama-globe valves, ama-globe valves, ama-plug valve, ama-valve, ama-disc valve nama-diaphragm.

(2) i-valve yokuhlola: i-valve yokuhlola yaziwa nangokuthi i-throttle valve noma i-valve yokuhlola, umphumela wayo ukugwema okuphakathi epayipini elikhuphuka nomfula. Iphampu ye-Centrifugal hygroscopic off valve bottom valve nayo ingeyesigaba sevalvu yokuhlola.

(3) valvu: umsebenzi wesigaba se-valve yokuphepha ukugwema ukucindezela kokusebenza kwento ephakathi epayipini noma okokusebenza kuphezulu kunevelu eshiwo, ukuze kufezwe umgomo wokuvikela ukuphepha.

(4) i-valve elawulayo: isigaba se-valve esilawulayo sihlanganisa i-valve elawulayo, i-valve yendlela eyodwa yokudonsa kanye ne-valve elawula ukucindezela, umphumela wayo ukulungisa ukucindezela kokusebenza kwe-medium, ukugeleza okuphelele nokunye okuthathu.

(5) ivelufa yokuhlukanisa: isigaba se-shunt valve sihlanganisa izinhlobonhlobo zamavalvu ezindlela eziningi nezicupho zesitimu, njll., umphumela wawo uwukukhipha, ukuhlukanisa noma ukuxuba okuphakathi epayipini.

2. Ukuhlukaniswa ngesigaba sephawundi

(1) I-vacuum valve: ibhekisela kuvalvu ukucindezela kwayo kungaphansi komfutho womoya ojwayelekile.

(2) I-valve ye-voltage ephansi: ibhekisela esigabeni sephawundi PN ¡Ü 1.6mpa valve.

(3) i-valve yokucindezela okuphakathi: ibhekisela ekucindezelweni okuzisholo kwe-PN ngu-2.5, 4.0, 6.4Mpa valve.

(4) I-valve yokucindezela okuphezulu: ibhekisela ku-valve enengcindezi yokusebenza PN engu-10 ~ 80Mpa.

(5) i-valve yomfutho ophezulu: ibhekisela kuvalvu ye-PN¡Ý100Mpa.

3. Hlela ngokwezinga lokushisa lokusebenza

(1) low temperature valve: for medium operating temperature t (1) i-valve yokushisa ephansi: yokushisa okuphakathi kokusebenza t

(2) i-valve yokushisa ephansi: izinga lokushisa eliphakathi lokusebenza -100¡æ¡Ü T ¡Ü-40¡æ valve.

(3) I-valve yokushisa evamile: izinga lokushisa eliphakathi lokusebenza -40¡æ¡Ü T ¡Ü120¡æ valve.

(4) I-valve yokushisa ephakathi nendawo: yokushisa okuphakathi kokusebenza okungu-120¡æ

(5) i-valve yokushisa ephezulu: yokushisa okuphakathi kokusebenza T >450¡æ valve.

4. Hlukanisa ngokwefomu lephromoshini

(1) I-valve ezenzakalelayo ayiwona amandla angaphandle okukhuthaza, kodwa ngamandla omthombo ngokwawo okwenza indawo yevalvu yevalvu. Njenge-valve, i-valve elawula ingcindezi, i-steam trap, i-valve yokuhlola, i-valve yokulawula okuzenzakalelayo nokunye.

(2) I-valve yokulawula amandla okushayela: i-valve yokulawula amandla okushayela ingasebenzisa izinhlobonhlobo zamadivayisi wamandla ukukhuthaza.

I-valve yokulawula kagesi: incike kubunjiniyela bamandla ukukhuthaza i-valve.

I-valve ye-pneumatic: i-valve eqhutshwa ukucindezelwa komoya.

I-valve ye-Hydraulic: i-valve eqhutshwa ukucindezela koketshezi olufana nowoyela.

Ngaphezu kwalokho, kukhona futhi izingxenye zezigaba ezingenhla zezindlela zokushayela, njengama-valve okulawula igesi-kagesi.

(3) I-valve eyenziwa ngesandla: i-valve yezandla incike ku-spindle, i-rocker, ibha yenduku, iketango le-sprocket, ngezinsiza zabantu ukulawula ukuma kwe-valve. Lapho i-valve yokuvula nokuvala i-torque inkulu uma kuqhathaniswa, isondo noma isinciphisi segiya lezikelemu singasethwa phakathi kwe-spindle nesihlalo. Uma kunesidingo, ama-cardan joints kanye nama-shafts ajikelezayo nawo angasetshenziswa ekusebenzeni okusebenzayo okude.

5, ngokuya ngezigaba zobubanzi obujwayelekile

(1) I-valve yobubanzi obuncane: i-diameter encane DN¡Ü40mm valve.

(2) I-valve yobubanzi obumaphakathi: i-valve engu-DN engu-50 ~ 300mm.

(3) I-valve yodayamitha enkulu: i-valve yodayamitha engu-DN engu-350 ~ 1200mm valvu.

(4) I-valve enkulu kakhulu: ivalvu enobubanzi obuncane DN¡Ý1400mm.

6. Hlukanisa ngokohlobo lwesakhiwo

(1) umumo we-valve: izingxenye zokuvula nokuvala (i-piston valve) zishayelwa isihlalo eduze kwe-axis ye-valve yesango elinomfutho ophezulu ukuze kulungiswe ukunyakaza kokufaneleka;

(2) umumo we-valve yepulaki: izingxenye ezivulayo nezivalayo (i-valve yembulunga) ziphushwa isihlalo se-valve eduze kwe-eksisi ye-valve yesango yokucindezela okukhulu evundlile ukuze kulungiswe ukunyakaza komzimba;

(3) vala ipulaki: izingxenye ezivulayo nezivalayo (ipulaki lekhoni noma ibhola) ngokuqinile eduze nokujikeleza kwe-eksisi;

4

5

(6) Ulayini wephampu wepuleti elijikelezayo: izingxenye ezivulayo nezivalayo ziyagingqika zibheke kumzila wokuphepha oma mpo ophindwe kabili.

7. Hlukanisa ngokwemodi yokuxhuma

(1) I-valve yokuxhuma ene-flanged: umzimba we-valve uqukethe intambo noma intambo yepayipi, exhunywe ne-flange yepayipi.

(2) I-valve yokuxhuma ene-flange: umzimba we-valve uqukethe i-flange plate, exhunywe ne-flange yepayipi.

(3) i-valve yokuxhuma i-welding welding kagesi: umzimba we-valve uqukethe umthungo we-welding welding kagesi, nokuxhumeka kwepayipi lokushisela.

(4) I-valve yokuxhuma i-clamp: umzimba we-valve uqukethe i-clamp futhi uxhunywe ne-clamp yepayipi.

(5) Ivalvu yokuxhuma ehlangene yohlobo lomkhono: ngokukhethwa kwepayipi lokuxhumana okuhlangene kohlobo lomkhono.

(6) I-valve yokuxhuma i-wafer: imodi yokuxhuma ivalvu namapayipi nhlangothi zombili aboshelwe ndawonye ngokushesha ngebhawodi yaphansi.

8, ngokusho kwempahla yomzimba ye-valve

(1) I-valve yensimbi: umzimba we-valve nezinye izingxenye zenziwe ngezinto zensimbi. Okufana ne-pig iron valve, i-carbon steel valve, i-alloy steel valve, i-alloy copper valve, i-aluminium alloy profile valve, i-aluminium alloy valve, i-titanium valve, i-valve ye-Monel alloy, njll.

(2) i-valve engeyona eyensimbi: umzimba we-valve nezinye izingxenye zenziwe ngezinto ezingezona ezensimbi. Njenge-valve yepulasitiki, i-ceramic valve, i-valve elayishiwe, i-valve ye-FRP evimbela ukubola, njll.

(3) i-valve yensimbi yomzimba we-valve: idizayini yokubukeka komzimba we-valve yezinto zensimbi, isakhiwo sangaphakathi lapho ukuthintana nendawo ephakathi kuvame ulwelwesi olungaphezulu, njengomsabalalisi kawoyela, i-valve yepulasitiki, ivalvu ye-ceramic, njll.

Okwesibili, ukusebenza kahle kwe-valve yezitshalo zamakhemikhali

Uhlobo oluvulekile noluvaliwe: nqamula noma xhumanisa ubumanzi boketshezi kupayipi le-ac;

Ukulungisa uhlobo: lungisa inani lokugeleza okuphelele kanye nesivinini sokugeleza ku-tube;

Uhlobo lwe-valve ye-Throttle: yenza uketshezi ngokusho kwe-valve ngemva kokubangela ukucindezela okukhulu kakhulu kwegesi;

Ezinye izinhlobo: a. ukuvulwa nokuvala okuzenzakalelayo ngokugcwele B. ukugcina ingcindezi ethile yokusebenza C. ipayipi elivimba umusi lokudonsa amanzi.
