Ivalvu isetshenziselwa ukuvula nokuvala ipayipi, ukulawula isiqondiso sokugeleza, ukulungisa nokulawula imingcele yendawo yokudlulisa (izinga lokushisa, ukucindezela nokugeleza) izesekeli zamapayipi.Ngokusho komsebenzi wayo, ingahlukaniswa nge-valve yokuvala, i-valve yokuhlola, i-valve elawulayo, njll.

Ivalvu iyingxenye yokulawula kusistimu yokudlulisa uketshezi, enemisebenzi yokunqamula, ukulawula, ukuphambukisa, ukuvimbela okuphambene, ukuqiniswa kwengcindezi, ukuphambukisa noma ukukhulula ukuchichima, njll. Amavaluvu ezinhlelo zokulawula uketshezi asukela kumavalvu embulunga alula ukuya lawo asetshenziswa ezinhlelweni ezishintshayo eziyinkimbinkimbi kakhulu.

Amavalvu angasetshenziswa ukulawula ukugeleza komoya, amanzi, isitimu, imidiya egqwalayo, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya ekhipha imisebe nezinye izinhlobo zoketshezi.Amavalvu ngokuya ngezinto ezibonakalayo nawo ahlukaniswe abe ama-valve ensimbi, ama-valve ensimbi, ama-valve ensimbi engagqwali (201, 304, 316, njll.), ama-valve ensimbi e-chromium molybdenum, ama-valve ensimbi e-chromium molybdenum vanadium, ama-valve ensimbi anesigaba esiphindwe kabili, ama-valve epulasitiki. , ama-valve angokwezifiso angajwayelekile.

I-valve ikusistimu yoketshezi, esetshenziselwa ukulawula isiqondiso soketshezi, ingcindezi, ukugeleza kwedivayisi, iwukwenza ipayipi nezinto zokusebenza phakathi (uketshezi, igesi, impushana) zigeleze noma zimise futhi zilawule ukugeleza kwedivayisi. .

Ivalvu iyingxenye yokulawula yesistimu yokudlulisa uketshezi lwamapayipi, esetshenziselwa ukushintsha ingxenye yephaseji kanye nendawo yokugeleza okumaphakathi, ngokuphambukisa, ukunqamula, ukugoqa, isheke, ukuphambukisa noma imisebenzi yokukhulula ingcindezi.I-valve esetshenziselwa ukulawula uketshezi, kusukela ku-valve yembulunga elula kakhulu kuya ohlelweni lokulawula oluzenzakalelayo oluyinkimbinkimbi kakhulu olusetshenziswa ezinhlobonhlobo zamavalvu, ukuhlukahluka kwawo kanye nokucaciswa kwawo, usayizi ovamile we-valve kusukela ku-valve yensimbi encane kakhulu kuya kusayizi wepayipi lezimboni. valve kufika ku-10m.Ingasetshenziselwa ukulawula amanzi, umusi, uwoyela, igesi, udaka, izinhlobonhlobo zemidiya egqwalayo, insimbi ewuketshezi kanye noketshezi olukhipha imisebe nezinye izinhlobo zokugeleza koketshezi, ukucindezela kokusebenza kwe-valve kungaba kusuka ku-0.0013MPa kuye ku-1000MPa we-ultra-high. ukucindezela, izinga lokushisa lokusebenza lingaba ngu-C-270 ℃ wokushisa okuphansi kakhulu kuya ku-1430 ℃ wokushisa okuphezulu.

I-valve ingalawulwa ngezindlela ezihlukahlukene zokudlulisela, njenge-manual, kagesi, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electromagnetic, i-electro-hydraulic, i-electro-hydraulic, i-gas-hydraulic, i-spur gear, i-bevel gear drive;Ngokucindezela, izinga lokushisa noma elinye uhlobo ngaphansi kwesenzo sezimpawu zezinzwa, isenzo, ngokuya ngemfuneko yokubhukha noma ayincikile kumasiginali wezinzwa ukuze uvuleke kalula noma uvale shaqa, uthembele kudrayivu noma kumshini othomathikhi owenza i-valve yokuvula nokuvala ukuphakamisa, ukushelela, indawo noma ukunyakaza okuzungezayo, ukuze ushintshe usayizi wembobo ukuze ubone umsebenzi wokulawula.
