Umsebenzi wesihlalo se-valve: esetshenziselwa ukusekela indawo evalwe ngokugcwele ye-valve core futhi yakhe ipheya yokuvala.

Umsebenzi Wediski: I-Disc – idiski eyindilinga elenza libe phezulu futhi linciphise ukwehla kwengcindezi. Kuqiniswe ukuze kwandiswe impilo yesevisi.

Indima ye-valve core: I-valve core ekucindezelwenii-valve yokunciphisaingenye yezingxenye eziyinhloko zokulawula ingcindezi.

Izici zesihlalo se-valve: Ukugqwala nokumelana nokugqoka; Isikhathi eside sokusebenza; Ukumelana nokucindezela okuphezulu; Ukunemba okuphezulu kwe-dimensional; Ukumelana okuhle kakhulu kwemithwalo ye-thrust kanye namazinga okushisa aphezulu; Ifanele izimoto eziningi zabagibeli, amaloli amancane nasindayo, izinjini zikadizili kanye nezinjini zezimboni ezimile.

Izici ze-valve disc: Inomsebenzi wokuma olungisekayo ukuvimbela udonga lwegobolondo lomzimba we-valve ukuthi lungangeni. Ivalve yokuhlola ipuleti le-clamshell butterfly inephini lehinge le-butterfly eyakhelwe ngaphakathi, elingagcini nje ngokuqeda ukuthi kungenzeka iphinikhodi ibhoboze indlu yevalvu ukuze ivuze, kodwa futhi yenza isihlalo sevalvu silungiseke kalula ngoba ubakaki owenziwe ngomshini uhambisana nendawo yesihlalo sevalvu. Lungisa idiski/isihlalo.

Izici ze-valve core: Lapho umgogodla ozungezayo uzungeza, imfoloko esekupheleni kwenkaba ezungezayo ishayela ipuleti levalvu elinyakazayo ukuze lijikeleze, ukuze imbobo yokukhipha amanzi epuleti le-valve elihambayo lihambisane nembobo yokungena kwamanzi epuleti levalvu ehambayo. ipuleti le-valve elimile, futhi ekugcineni amanzi ageleza ephuma kumongo ojikelezayo. Ngokuphuma kwe-hole, lo mklamo usetshenziswa kabanzi ezindaweni ezikhipha izimpompi.

Ukubuka konke kwesihlalo se-valve: Sebenzisa impahla enwebekayo yokuvala kanye ne-actuator thrust encane ukuze uthole isivalo esingangenisi umoya. Ukucindezelwa kokuvala kokuminyanisa isihlalo se-valve kubangela ukuthi okokusebenza kugxumeke ngendlela enwebekayo futhi kumpintshe endaweni emagebhugebhu yengxenye yensimbi yokukhwelana ukuze kuxhunywe noma yikuphi ukuvuza. indlela. Ukuvuza kwezinto eziwuketshezi kuyisisekelo sokuvuza okuncane.

Uhlolojikelele lwe-valve disc: indandatho yokuvala i-disc yohlobo lwesiketi. Imodeli yensiza idalula indandatho yokuvalwa kwediski yohlobo lwesiketi. Isici sayo sesakhiwo ukuthi uphawu phakathi kwendandatho yokuvala kanye nomzimba wediski ye-valve kuwumugqa onqamule kabili. Isigaba se-longitudinal endaweni yokuvala phakathi kwendandatho yokuvala kanye nomzimba we-valve disc yisikhala sendiza ye-trapezoidal.

Uhlolojikelele lwe-valve core: I-valve core ingxenye ye-valve esebenzisa ukunyakaza komzimba we-valve ukufeza imisebenzi eyisisekelo yokulawula isiqondiso, ukulawula ingcindezi noma ukulawula ukugeleza.

Ingxenye yobuso obungahlukaniseki kuvalvu isetshenziselwa ukusekela indawo evalwe ngokugcwele ye-valve core futhi yakhe ipheya yokuvala. Ngokuvamile, i-diameter yesihlalo se-valve yi-diameter enkulu yokugeleza kwe-valve. Isibonelo, ama-butterfly valves afika ezintweni ezihlukahlukene zokuhlala. Impahla yesihlalo sevalvu ingenziwa ngenjoloba ehlukahlukene, ipulasitiki, nezinto zensimbi, njenge: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE, njll.

Izinto ezibonakalayo okufanele zicatshangelwe lapho kukhethwa isihlalo se-valve ethambile yilezi:
1) Ukuhambisana koketshezi, okuhlanganisa ukuvuvukala, ukulahlekelwa ubulukhuni, ukungena nokuwohloka;
2) Ubulukhuni;
3) Ukuguqulwa okuhlala njalo;
4) Izinga lokubuyisela ngemva kokukhipha umthwalo;
5) Amandla aqinile futhi acindezelayo;
6) Ukuguqulwa ngaphambi kokuqhekeka;
7) Imoduli ye-elastic.

Idiski

I-valve disc iwumgogodla we-valve, okungenye yezingxenye eziyinhloko ze-valve. Ithwala ngokuqondile ukucindezela okuphakathi ku-valve. Izinto ezisetshenziswayo kufanele zihambisane nemithetho ye-“Valve Pressure and Temperature Class”.

Izinto ezisetshenziswa kakhulu zihlanganisa okulandelayo:

Uma kubhekwa izinga lamanje lobuchwepheshe basekhaya, izimboni ezihlukahlukene azilingani, futhi ukuhlolwa kwabasebenzisi kuvame ukuba nobunzima. Ngokusekelwe kokuhlangenwe nakho, kunconywa ukuthi i-PN≤2.5MPa kanye nokokusebenza kwe-valve kufanele kube yinsimbi ukuze kuqinisekiswe ukuphepha.
4. I-acid high-silicon ductile iron ukumelana ne-asidi: ifanele imidiya egqwalayo enokucindezela okuzisholo okungu-PN ≤ 0.25MPa kanye nezinga lokushisa elingaphansi kuka-120°C.
5. Insimbi ye-Carbon: ifanele imidiya efana namanzi, isitimu, umoya, i-hydrogen, i-ammonia, i-nitrogen nemikhiqizo ye-petroleum enomfutho wegazi ongu-PN ≤ 32.0MPa kanye nezinga lokushisa elingu--30 ~ 425°C. Amamaki asetshenziswa kakhulu afaka i-WC1, i-WCB, i-ZG25, insimbi yekhwalithi ephezulu engu-20, i-25, i-30 kanye nensimbi ye-alloy ephansi engu-16Mn.
6. Ingxubevange yethusi: ilungele amanzi, amanzi olwandle, umoya-mpilo, umoya, uwoyela kanye neminye imidiya ene-PN≤2.5MPa, kanye nemidiya ye-steam enezinga lokushisa elingu-40 ~ 250℃. Amabanga asetshenziswa kakhulu ahlanganisa i-ZGnSn10Zn2 (ithusi le-tin), i-H62, i-Hpb59-1 (ithusi), i-QAZ19-2, i-QA19-4 (ithusi le-aluminium).
7. Ithusi lokushisa okuphezulu: ifaneleka kumikhiqizo ye-steam ne-petroleum ene-pressure yegama elithi PN≤17.0MPA kanye nezinga lokushisa ≤570℃. Amabanga asetshenziswa kakhulu ahlanganisa i-ZGCr5Mo, 1Cr5M0, ZG20CrMoV, ZG15Gr1Mo1V, 12CrMoV, WC6, WC9 namanye amabanga. Ukukhetha okuqondile kufanele kuhambisane nokucindezela kwe-valve kanye nezincazelo zokushisa.
8. Insimbi enezinga lokushisa eliphansi, ifanele ingcindezi okuzisholo ukuthi PN≤6.4Mpa, izinga lokushisa ≥-196℃ ethylene, propylene, igesi yemvelo ewuketshezi, i-nitrogen ewuketshezi kanye neminye imithombo yezindaba, izinhlobo ezisetshenziswa ngokuvamile) ihlanganisa i-ZG1Cr18Ni9, 0Cr18Ni9, 1CrNiG9NiG9Insimbi ye-Z8G9. insimbi engamelana ne-asidi, ifanele Ngomfutho wegazi ongu-PN≤6.4Mpa, izinga lokushisa ≤200℃ nitric acid, i-acetic acid neminye imidiya, izinhlobo ezivame ukusetshenziswa yi-ZG0Cr18Ni9Ti, ZG0Cr18Ni10 , ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti

i-valve core
I-valve core ingxenye ye-valve esebenzisa ukunyakaza kwayo ukuze kuzuzwe imisebenzi eyisisekelo yokulawula isiqondiso, ukulawula ingcindezi noma ukulawula ukugeleza.

Ukwahlukanisa
Ngokwemodi yokunyakaza, ihlukaniswe yaba uhlobo lokujikeleza (45 °, 90 °, 180 °, 360 °) nohlobo lokuhumusha (radial, directional).
Ngokusho komumo, ingahlukaniswa ibe yindilinga (i-valve yebhola), i-conical (i-plug valve), i-disc (i-valve uvemvane, i-valve yesango), i-dome-shaped (i-stop valve, i-valve yokuhlola) kanye ne-cylindrical (i-valve ehlehlisayo).
Ngokuvamile eyenziwe ngethusi noma insimbi engagqwali, kukhona namapulasitiki, inayiloni, izitsha zobumba, ingilazi, njll.
I-valve core ku-valve yokunciphisa ingcindezi ingenye yezingxenye eziyinhloko zokulawula ingcindezi.
