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. I-valve yokuhlola ipuleti le-clamshell butterfly eyingqayizivele inephini lehinge le-butterfly eyakhelwe ngaphakathi, elingagcini nje ngokuqeda ukuthi kungenzeka iphini lehinge libhoboze indlu ye-valve ukuze livuze, kodwa futhi lenza isihlalo se-valve silungiseke kalula ngoba ubakaki owenziwe ngomshini uhambisana indawo yokuhlala ye-valve. Lungisa idiski/isihlalo.

Izici ze-valve core: Uma umgogodla ozungezayo uzungeza, imfoloko esekupheleni kwenkaba ezungezayo ishayela ipuleti le-valve elinyakazayo ukuze lijikeleze, ukuze imbobo yokukhipha amanzi epuleti le-valve elihambayo lihambisane nembobo yokufaka amanzi endaweni ehambayo. ipuleti le-valve. 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:
1. I-Grey cast iron: Insimbi eyi-Gray cast ifanele amanzi, umusi, umoya, igesi, uwoyela kanye neminye imidiya enomfutho ojwayelekile we-PN ≤ 1.0MPa kanye nezinga lokushisa elingu--10°C kuya ku-200°C. Amabanga asetshenziswa kakhulu ensimbi empunga yilawa: HT200, HT250, HT300, kanye neHT350.
2. Insimbi exutshwe nensimbi: ilungele amanzi, isitimu, umoya kanye nemidiya kawoyela enokucindezela okuzisholo okungu-PN≤2.5MPa kanye nezinga lokushisa elingu--30~300℃. Amabanga asetshenziswa kakhulu afaka: KTH300-06, KTH330-08, KTH350-10.
3. I-Ductile iron: ifanele amanzi, umusi, umoya, uwoyela kanye neminye imidiya ene-PN≤4.0MPa kanye nezinga lokushisa -30~350℃. Amabanga asetshenziswa kakhulu afaka: QT400-15, QT450-10, QT500-7.
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 kakhulu) ihlanganisa i-ZG1Cr18Ni9, 0Cr18Ni9, 1CrNiG9Cr. insimbi engamelana ne-asidi, efanelekile Ngengcindezi okuzisholo yona i-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.
