I-Valve seal ring izinto ezivamile nezimo zesevisi I-valve yesango yegesi ye-valve

Izinto zokuvala ama-valve zinezigaba ezimbili zensimbi nezingezona ezensimbi. Izinto ezijwayelekile nezimo zazo zokusebenzisa zimi kanje:
1. Irabha yokwenziwa
Irabha yokwenziwa ingcono kunerabha yemvelo ekumelana nowoyela, ukumelana nezinga lokushisa nokungagqwali. Izinga lokushisa elijwayelekile lenjoloba yokwenziwa t ≤ 150℃, irabha yemvelo t ≤ 60℃, irabha esetshenziselwa ukucindezela okuzisholo kwe-PN ≤ 1MPa valvu yeglobhu, i-valve yesango, i-diaphragm valve, i-valve uvemvane, i-valve yesheke, i-valve yokubopha namanye ama-valve seal.
2, inayiloni
Inayiloni inezici ze-coefficient ephansi yokungqubuzana nokumelana nokugqwala okuhle. Inayiloni ikakhulukazi isetshenziselwa izinga lokushisa t ≤ 90 ℃, ingcindezi okuzisholo PN ≤ 32MPa ibhola valve, valve imbulunga.
3. I-Teflon
I-Ptfe isetshenziswa kakhulu kumavalvu embulunga, amavalvu esango namavalve ebhola anezinga lokushisa elingu-T ≤ 232℃ kanye nengcindezi yegama elithi PN ≤ 6.4MPa.
4, insimbi
I-Cast iron isetshenziselwa ama-valve esango, ama-valve embulunga kanye namapulaki ama-valve egesi namafutha, ngezinga lokushisa elingu-T ≤ 100℃ kanye nengcindezi yegama elithi PN ≤ 1.6mpa.
5. Ingxubevange ye-Babbitt
Ingxubevange ye-Babbitt isetshenziselwa ama-valve okumisa i-ammonia anezinga lokushisa elingu-T-70 ~150℃ kanye nengcindezi yegama elithi PN ≤ 2.5MPa.
6. Ingxube yethusi
Izinto ezivamile ze-alloy yethusi ziyi-6-6-3 tin bronze kanye ne-58-2-2 yethusi ye-manganese. Ingxubevange yethusi ukumelana nokugqoka, ifanele izinga lokushisa T ≤ 200℃, ingcindezi okuzisholo PN ≤ 1.6MPa amanzi kanye isitimu, ngokuvamile asetshenziswa amavalvu esangweni, ama-valve embulunga, hlola valves, plug valve, njll.
7, insimbi engagqwali ye-chrome
Imikhiqizo yensimbi engagqwali ye-Chrome evame ukusetshenziswa yi-2Cr13, 3Cr13 ngemuva kokwelashwa kokucisha nokushisa, ukumelana nokugqwala okuhle. Ivamise ukusetshenziselwa izinga lokushisa elingu-t ≤ 450℃, ingcindezi yegama elithi PN ≤ 32MPa amanzi, umusi namafutha kanye namanye ama-valve emidiya.
8, i-chromium nickel titanium insimbi engagqwali
Uhlobo oluvame ukusetshenziswa lwensimbi engagqwali ye-chromium nickel yi-1Cr18Ni9ti, enokumelana nokugqwala okuhle, ukumelana nokuguguleka nokumelana nokushisa. Ifanele izinga lokushisa T ≤ 600℃, ingcindezi okuzisholo PN ≤ 6.4MPa umusi, i-nitric acid neminye imidiya, esetshenziselwa i-valve yeglobhu, i-valve yebhola, njll.
9, insimbi ye-nitriding
Ibanga elijwayelekile lensimbi ye-nitriding ngu-38CrMoAlA, enokumelana nokugqwala okuhle kanye nokumelana nokuhuzuka ngemuva kokungcwatshwa kwe-carburizing. Ngokuvamile isetshenziselwa ama-valve esango lesiteshi samandla anezinga lokushisa elingu-T ≤ 540℃ kanye nokucindezela okuzisholo kwe-PN ≤ 10MPa.
10, ukubhoboza
I-Boronizing ngumzimba noma i-disc body material ecutshungulwe ngokuqondile indawo yokubeka uphawu, i-boronizing surface treatment, ukuvala uphawu kokumelana nokugqoka kuhle kakhulu. Isetshenziselwa i-valve ye-blowdown yezitshalo zamandla.
Ivalve yesango legesi Ivalvu yesandla Jikisa ngesandla isondo lesandla ukuze wenze isiqu sikhuphuke futhi siwe, ukuze ushayele ipuleti lesango liye phezulu naphansi ukuze uvule futhi uvale ivalvu. Ivalvu Ihlonyiswe “NGOKUVULA” KANYE “NOKUVALA” OKUKHOMBISA IWASHI, PHENDUKELELA IWASHI, ISANGO LIYAWA, Isikhombi sikhombe ESIKHUNDWENI “ESIVALAYO,” FUTHI IVAVASI IVALIWE. Vula I-COUNTERCOCKWISE, ISANGO LIPHUKA, INALITHI ikhombe ESIKHUNDLENI “SOKUVULA”, FUTHI IVULEKILE IVALI. Lapho uhlola ingcindezi yepayipi, kuyadingeka ukusebenzisa isondo lesandla senduku enwetshiwe. Vala i-valve futhi kufanele ivale endaweni (bheka indawo yesikhombi). Vula isondo lesandla ngokwewashi ukuze uvale, futhi uliphendule liphikisane newashi ukuze uvule.
Ibanga elingu-1.
Amavalvu esango legesi eliqhutshwa ngesandla anobubanzi obuncane be-DN100mm~300mm kanye nokucindezela okulinganiselwe kwe-PN0.8mpa okuxhunywe ekugcineni okuphekiwe kufakiwe kulokhu kucaciswa.
2. Sebenzisa
2.1 Le valve isetshenziswa njengesisetshenziswa sokuvula nokuvala emapayipini egesi yedolobha kanye negesi yemvelo.
2.2 Khetha impahla ye-valve ngokuya ngendlela.
2.2.1 I-valve yensimbi eyi-Ductile ifanele igesi, igesi yemvelo kanye nokunye.
2.3 Izinga lokushisa elisebenzayo:
2.3.1 Izinga lokushisa elisebenzayo le-ductile iron valve ngu-≤120℃
Isakhiwo sesi-3.
3.1 Isakhiwo esiyisisekelo se-valve yesango legesi sikhonjiswe kuMfanekiso 1
3.2 I-gasket yezingxenye zokugqoka igcwaliswa ngebhodi le-asbestos lerabha kanye nerabha ye-fluorine ukuqinisekisa ukuvaleka okuthembekile.
4. Ukusebenza
AMAVAVAVA Aphathwayo APHENDULELA ISANDLA NGESANDLA UKUZE APHAKAMISE FUTHI Ehlise ISIQINISO, ngaleyo ndlela ESHAYELA Isango ELIPHEZULU NASENSI UKUZE LIVULE FUTHI LIVALE IVAVVU. Ivalvu Ihlonyiswe “NGOKUVULA” KANYE “NOKUVALA” OKUKHOMBISA IWASHI, PHENDUKELELA IWASHI, ISANGO LIYAWA, Isikhombi sikhombe ESIKHUNDWENI “ESIVALAYO,” FUTHI IVAVASI IVALIWE. Vula I-COUNTERCOCKWISE, ISANGO LIPHUKA, INALITHI ikhombe ESIKHUNDLENI “SOKUBA PHEZU KWAYO,” FUTHI IVULEKILE IVALI.
5. Ukugcinwa, ukugcinwa, ukufakwa kanye nokusetshenziswa
5.1 Ivalvu kufanele igcinwe ekamelweni elomile nelingena umoya, futhi amaphethelo womabili wephaseji yevalvu ayovinjwa.
5.2 Amavalvu agcinwe isikhathi eside kufanele ahlolwe njalo ukuthi angcolile yini. Ukunakwa okukhethekile kufanele kukhokhwe ekuhlanzweni kwendawo yokuvala ukuvimbela ukulimala kwendawo yokubeka uphawu.
5.3 Ngaphambi kokufaka, hlola ngokucophelela ukuthi umaki wevalvu uyahambisana yini nezidingo zokusebenzisa.
5.4 Ngaphambi kokufakwa, igumbi elingaphakathi nendawo yokuvala ivalvu kufanele ihlolwe. Uma kukhona ukungcola, kufanele kuhlanzwe ngendwangu yokuhlanza.
5.5 Amapayipi kufanele ahlanzwe ngaphambi nangemva kokufakwa ukuze kuqinisekiswe ukuthi akukho nsalela emapayipini.
5.6 Lapho kuhlolwa ingcindezi yepayipi, isondo lesandla senduku enwetshiwe kufanele kusetshenziswe. Vala i-valve futhi kufanele ivale endaweni (bheka indawo yesikhombi). Vula isondo lesandla ngokwewashi ukuze uvale, futhi uliphendule liphikisane newashi ukuze uvule.
5.7 I-valve kufanele ivuthelwe njalo ukuvimbela ukuphekwa.
5.8 Ivalvu kufanele igcotshwe njalo (izinsuku eziyi-10 ~ 15) ukuze kugcotshwe ipheya yokuvala kanye nesiqu se-valve namanye amapheya anyakazayo ukuze kuncishiswe i-torque yokushintsha nokuvikela ipheya yokuvala.
6. Amaphutha okungenzeka, izimbangela, kanye nezindlela zokuxazulula izinkinga zibalwe kuthebula
Ithebula 1 Amaphutha angenzeka, izimbangela, kanye nezindlela zokuxazulula inkinga 1
Iwaranti engu-7.
Umkhiqizi unesibopho sewaranti yevalvu phakathi nonyaka owodwa ngemva kokusetshenziswa, kodwa kungakapheli izinyanga eziyi-18 ngemva kokulethwa. Ngesikhathi sewaranti, ngenxa yezizathu zekhwalithi yomkhiqizo ingakhandwa noma ishintshwe.
8. Imiyalo yoku-oda
Sicela usho uma u-oda
Ukucindezela okubizwa nge-MPa
Ubukhulu obuncane mm
Izinga lobude besakhiwo
Usayizi wokuxhumeka kwe-Flange ojwayelekile
Ngedivayisi engagcotshi amafutha
Idivayisi yesondo lesandla nobukhulu ngenduku yokunweba noma ngaphandle kwayo
