Izidingo zokufakwa kwamavalvu esiteshi samandla izinzuzo zesakhiwo kanye nokucaciswa kobuchwepheshe
I-valve ikusistimu yoketshezi, esetshenziselwa ukulawula indlela uketshezi, ingcindezi, idivayisi egeleza ngayo, okokwenza ipayipi nezinto zokusebenza endleleni (uketshezi, igesi, impushana) ukugeleza noma ukuma futhi ingalawula ukugeleza kwedivayisi. I-valve iyingxenye yokulawula yesistimu yokudlulisa uketshezi lwamapayipi, esetshenziselwa ukushintsha ingxenye yendlela kanye nendawo yokugeleza okumaphakathi, ngokuphambukisa, ukunqamula, ukunyakazisa, ukuhlola, i-shunt noma ukukhululeka kwengcindezi echichimayo neminye imisebenzi. Amavaluvu okulawula uketshezi asukela kumavalvu embulunga alula kuya kulawo asetshenziswa ezinhlelweni zokulawula ezizenzakalelayo eziyinkimbinkimbi kakhulu, ezinezinhlobonhlobo zezinhlobo kanye nokucaciswa, okusukela ngosayizi abavamile ukusuka kumavalvu ensimbi amancane kakhulu kuye kumapayipi epayipi emboni afika ku-10m. Ingasetshenziswa ukulawula ukugeleza kwamanzi, umusi, uwoyela, igesi, udaka, zonke izinhlobo zemidiya ezonakalisayo, insimbi ewuketshezi kanye noketshezi olukhipha imisebe nezinye izinhlobo zoketshezi, ingcindezi yokusebenza kwe-valve ingaba kusuka ku-0.0013mpa kuya ku-1000MPa ukucindezela okuphezulu, izinga lokushisa lokusebenza kungaba C-270 ℃ ukuze 1430 ℃ izinga lokushisa eliphezulu. Ukulawula i-valve kungasebenzisa imodi yokudlulisa ehlukahlukene, njenge-manual, kagesi, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electric hydraulic, i-hydraulic kagesi, i-pneumatic, i-spur gear, i-bevel gear drive, njll; 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. Izidingo zokufaka 1, ngaphambi kokufakwa kwe-valve, kufanele uhlole ngokucophelela imodeli ye-valve, ukucaciswa nokuklama; 2, ngokusho kwemodeli ye-valve kanye nemiyalelo yefekthri ukuhlola ukuthi i-valve ingasetshenziswa yini ezimweni ezidingekayo; 3. Lapho uphakamisa i-valve, intambo kufanele iboshwe ekuxhumekeni kwe-flange yomzimba we-valve kanye nesembozo se-valve, futhi ingaboshelwa ku-handwheel noma isiqu, ukuze ungalimazi isiqu kanye nesondo lesandla; 4. Uma i-valve ifakwe epayipini elivundlile, isiqu se-valve kufanele sibheke phezulu, futhi asivunyelwe ukufakwa phansi; 5, lapho ufaka i-valve, akufanele isebenzise imodi yokuxhuma ngababili ngenkani, ukuze ingabangeli umonakalo ngenxa yamandla angalingani; 6, i-valve yesango le-stem akufanele ifakwe endaweni emanzi engaphansi komhlaba, ukuze ingavimbeli ukugqwala. Izidingo zomhlangano izingxenye ezihlanzekile kufanele zivalwe ukuze zifakwe. Izidingo zenqubo yokufaka zimi kanje: 1. Indawo yokusebenzela yokufaka kufanele ihlanzeke, noma imise izindawo ezihlanzekile zesikhashana, njengendwangu esanda kuthengwa enombala noma ifilimu yepulasitiki, ukuvimbela uthuli ukuthi lungangeni ngesikhathi sokufakwa. I-2, izisebenzi zomhlangano kumele zigqoke izingubo zokusebenza zikakotini ezihlanzekile, zigqoke isigqoko sikakotini esihlanzekile, izinwele azikwazi ukuvuza, izinyawo zigqoke izicathulo ezihlanzekile, izandla zigqoke amagilavu epulasitiki, ukugcoba. 3, amathuluzi omhlangano kumele asuswe amafutha ngaphambi komhlangano, ukuqinisekisa ukuthi ahlanzekile. Izidingo Zokwamukela Ukwamukelwa kuhambisana ne-HG 20202-2000 Ikhodi Yokwakha Nokwemukelwa Kobunjiniyela Bokuqeda Igremu. Ngaphambi kokuhlanganisa, sula ingxenye ngayinye ngephepha lokuhlunga elinembayo elihlanzekile, khetha amakhona afile ezingxenye, futhi iphepha lokuhlunga elinombala ongashintshiwe liyafaneleka. 1, imodeli yevalvu kufanele ikhonjiswe ngokwezidingo zenombolo KAZWELONKE. Uma izinga lebhizinisi, kufanele libonise incazelo efanele yemodeli. I-2, ingcindezi yokusebenza kwe-valve, izidingo ≥ ingcindezi yokusebenza kwepayipi, ngaphandle kokuthinta intengo yendawo, i-valve ingathwala ingcindezi kufanele ibe mkhulu kunokucindezela kwangempela kwepayipi. 3, amazinga okukhiqiza ama-valve, kufanele achaze isisekelo senombolo Ejwayelekile KAZWELONKE, uma izinga lebhizinisi, inkontileka yokuthengwa kwempahla kufanele ifakwe kumbhalo webhizinisi. Ukuze uthole imininingwane eyengeziwe, sicela ubheke: Izidingo zokufakwa kweSakhiwo se-valve Izinzuzo kanye nemininingwane yobuchwepheshe ye-valve yesiteshi samandla “I-valve yesiteshi samandla”, eyaziwa nangokuthi i-valve yesiteshi samandla, isebenza ikakhulukazi epayipini lezinhlelo ezahlukahlukene zeziteshi zikagesi ezishisayo, ukunqanyulwa. noma ukuxhuma imidiya yamapayipi. Indawo esebenzayo: amanzi, isitimu nezinye izinto ezingagqwali. Uma kuqhathaniswa neminye imikhiqizo yama-valve, i-valve yesiteshi samandla ibonakala ngokushisa okuphezulu nokucindezela okuphezulu, umklamo oyingqayizivele wokuzivala, ukuphakama kwengcindezi, ukubekwa uphawu okuthembeke kakhulu. Ngenxa yokusebenza okukhethekile, izici zobuchwepheshe kanye nezimo zokusebenza, umkhiqizo wenze izici ukuthi eminye imikhiqizo ayikwazi ukushintshwa. Isihlalo se-valve kanye ne-disc sealing surface yenziwe nge-cobalt-based carbide plasma spray welding, enokumelana okuhle nokuhuzuka kanye nokumelana nokuhuzuka.
I. Ukwethulwa kafushane kwevalvu yesiteshi samandla
“I-valve yesiteshi sikagesi” yaziwa nangokuthi i-valve yesiteshi sikagesi, elungele kakhulu iziteshi zamandla ashisayo ezinhlelweni ezihlukene zamapayipi, anqanyulwe noma afakwe phakathi nendawo yamapayipi. Isisetshenziswa esisebenzayo: amanzi, isitimu kanye nokunye okungagqwali. Uma kuqhathaniswa neminye imikhiqizo yama-valve, i-valve yesiteshi samandla ibonakala ngokushisa okuphezulu nokucindezela okuphezulu, umklamo oyingqayizivele wokuzivala, ukuphakama kwengcindezi, ukubekwa uphawu okuthembeke kakhulu. Ngenxa yokusebenza okukhethekile, izici zobuchwepheshe kanye nezimo zokusebenza, umkhiqizo wenze izici ukuthi eminye imikhiqizo ayikwazi ukushintshwa.
