Umsebenzi oyisisekelo wevalvu unqanyuliwe-, ukulawulwa, ukuphambukisa, ukuvimbela i-countercurrent, isilawuli, i-shunt noma ukukhululeka kwengcindezi.
I-Valve (udumo) iyingxenye yesistimu yokulawula uketshezi, enqanyuliwe{0}}, ilawulwa, i-diversion, ukuvimbela isibali-samanje, i-voltage, i-shunt noma i-overflow pressure kanye neminye imisebenzi.
Amavalvu amasistimu okulawula uketshezi, kusukela kokuvala-amavalvu alula ukuya kububanzi obubanzi kakhulu bamavalvu asetshenziswa ezinhlelweni ezishintshashintshayo ezishintshashintshashintshayo, eza ngezinhlobonhlobo ezihlukahlukene kanye nosayizi. Amavaluvu angasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya egqwalayo, ama-slurries, amafutha, izinsimbi eziwuketshezi kanye nemidiya ekhipha imisebe. Amavalvu aphinde ahlukaniswe abe amavalvu ensimbi, amavalvu ensimbi, amavalvu ensimbi engagqwali (201,304,316, njll.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valves,-okungeyona into evamile yamavalvu ngokwezifiso .
Incazelo: Kusistimu yoketshezi, esetshenziselwa ukulawula isiqondiso soketshezi, ingcindezi, idivayisi yokugeleza. Amavalvu angamadivayisi avumela ukugeleza nokuma kwemidiya (uketshezi, igesi, impushana) kumapayipi namathuluzi futhi alawule ukugeleza kwawo. Amavaluvu angasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya egqwalayo, ama-slurries, amafutha, izinsimbi eziwuketshezi kanye nemidiya ekhipha imisebe. I-valve iyingxenye yokulawula ohlelweni lokulethwa koketshezi lwamapayipi. Isetshenziselwa ukuguqula-ingxenye yephaseji kanye nesiqondiso sokugeleza kwe-medium. I-valve inemisebenzi yokuphambukisa, yokusika-, ishaye phansi, ihlole, i-shunt noma ikhulule ingcindezi. Kumavalvu okulawula uketshezi, kusukela kusikwa okulula{8}}kuye kusistimu yokulawula ezenzakalelayo eyinkimbinkimbi kakhulu esetshenziswa kumavalvu ahlukahlukene, izinhlobonhlobo kanye nokucaciswa kwe-diameter ye-valve kusuka ku-valve yensimbi encane kakhulu ukuya kububanzi obungamamitha ayi-10 wamapayipi e-Industrial. I-valve ingasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi ezifana namanzi, umusi, uwoyela, igesi, udaka, imidiya eyonakalisayo ehlukahlukene, insimbi ewuketshezi noketshezi olukhipha imisebe. Ukucindezela kokusebenza kwevalvu kungahluka ukusuka ku-0.0013MPa kuye ku-1000MPa, izinga lokushisa lokusebenza Ukusuka -ku-269℃ultra{18}}izinga lokushisa eliphansi ukuya ku-1430℃lokushisa eliphezulu. Ukulawula i-valve kungasetshenziswa ngezindlela ezihlukahlukene zokudlulisa, ezifana ne-manual, ugesi, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electromagnetic, i-electro-hydraulic, i-pneumatic, i-spur gear, i-bevel gear drive, njll; kungaba ingcindezi, izinga lokushisa Noma ezinye izinhlobo zesignali yokuzwa, ngokuvumelana nezidingo ezinqunywe kusengaphambili zesenzo, noma ungathembeli kusignali yokuzwa ukuze uvule noma uvale kalula, i-valve ithembele ku-drive noma umshini ozenzakalelayo ukuze izingcezu zokuvula nokuvala zokuphakamisa, ukuslayida, ukushwibeka noma ukuguqula i-Movement, ngaleyo ndlela iguqule usayizi wendawo yokugeleza kwayo ukuze ufeze imisebenzi yayo yokulawula.
ukuhlukaniswa
1. Ngokwendima nenjongo yokuhlukanisa
(1) Izigaba zokunqamula: njenge-valve yesango, i-globe valve, i-plug valve, i-valve yebhola, i-butterfly valve, i-valve yenaliti, i-diaphragm valve. I-valve enqanyuliwe, eyaziwa nangokuthi -i-valve yesiyingi evaliwe, i-globe valve, indima yayo ukuxhuma noma ukusika okuphakathi epayipini.
(2){1}}uhlobo olungabuyisi: Uma ivalvu yokuhlola, ivalvu yokuhlola, eyaziwa nangokuthi{2}}i-valve yendlela eyodwa noma i-valve yokuhlola, ivalvu yokuhlola iyivalvu ezenzakalelayo, indima yayo iwukuvimbela ukugeleza emuva kwamapayipi emidiya ukuze kuvinjwe iphampu nokushayela Ukuhlehliswa kwesithuthuthu, kanye nokuvuza kwemidiya yesiqukathi. Iphampu yamanzi ephuma kuvalvu engezansi nayo ingeyesigaba sevalvu yokuhlola.

4. Ngokuya ngezigaba zedrayivu
Kuhlukaniswa ngemodi yokushayela kuhlukaniswe ngamavalvu azishintshayo, amandla-amavalvu ashayelwa kanye namavalvu enziwa ngesandla:
(1) Ivalvu ezenzakalelayo isho ukungadingi ukushayela kwangaphandle, kodwa thembela emandleni abezindaba uqobo ukwenza ivalvu yesenzo. Njenge-valve yokuphepha, i-valve yokunciphisa ingcindezi, i-steam trap, i-valve yokuhlola, i-valve yokulawula okuzenzakalelayo.
(2) Ivalvu{1}eshayelwa Amandla: Amandla{2}}ivalvu eshayelwa ingasebenzisa imithombo yamandla ehlukahlukene ukushayela. Ihlukaniswe ngama-valve kagesi, ama-pneumatic valves, ama-hydraulic valves nokunye. I-valve kagesi: ene-valve yokushayela kagesi. I-valve ye-pneumatic: ene-valve eqhutshwa umoya ecindezelwe. Ivalvu eHydraulic: Ngosizo lukawoyela kanye nokunye umfutho owuketshezi-oshayelayo.
Ngaphezu kwalokho kunezinhlanganisela ezimbalwa zezindlela zokushayela ezingenhla, njengegesi - ivalvu kagesi.
(3) i-valve ye-manual: i-valve ye-manual enesondo lesandla, isibambo, i-lever, i-sprocket, ngumuntu ukuphatha isenzo se-valve. Lapho i-torque yevalvu yokuvula nokuvala inkulu, igiya noma isinciphisi segiya lezikelemu singasethwa phakathi kwesondo lesandla nesiqu. Uma kudingekile, ungasebenzisa futhi i-universal joint kanye ne-drive shaft isikhathi eside{3}}sokusebenza.
5 ngokuya ngesigaba sobubanzi obujwayelekile
