Umsebenzi wesihlalo sevalvu: usetshenziselwa ukusekela indawo evaliwe ngokuphelele yengaphakathi levalvu futhi wakhe i-sealing pair.

Umsebenzi weDiski: Idiski – idiski eyindilinga ekhulisa ukuphakama futhi inciphise ukwehla kwengcindezi. Iqiniswe ukuze isebenzise isikhathi eside.

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

Izici zesihlalo se-valve: Ukugqwala nokumelana nokuguguleka; Isikhathi eside sokusebenza; Ukumelana nokucindezela okuphezulu; Ukunemba okuphezulu; Ukumelana okuhle kakhulu nemithwalo yokusunduza kanye namazinga okushisa aphezulu; Kufanelekela iningi lezimoto zabagibeli, amaloli alula nasindayo, izinjini zikadizili kanye nezinjini zezimboni ezimile.

Izici zediski ye-valve: Inomsebenzi wokubeka olungisekayo ukuvimbela udonga lwegobolondo lomzimba we-valve ukuthi lungangeni. I-valve yokuhlola i-clamshell butterfly plate ehlukile ine-pin hinge ye-butterfly plate eyakhelwe ngaphakathi, engagcini nje ngokuqeda ithuba le-pin hinge lokubhoboza indlu ye-valve ukuze ivuza, kodwa futhi yenza kube lula ukulungisa isihlalo se-valve ngoba i-bracket esetshenzisiwe ihambisana nobuso besihlalo se-valve. Lungisa idiski/isihlalo.

Izici ze-valve core: Lapho i-rounding core ijikeleza, ifoloko ekugcineni okungezansi kwe-rounding core iqhuba i-moving valve plate ukuthi ijikeleze, ukuze imbobo yamanzi epuletini le-valve elihambayo ihambisane nembobo yokungena kwamanzi epuletini le-valve elihambayo. Ukugeleza kwamanzi ngembobo, lo mklamo usetshenziswa kabanzi ezindaweni zokukhipha amanzi.

Ukubuka konke kwesihlalo se-valve: Sebenzisa izinto zokuvala ezinwebekayo kanye ne-actuator thrust encane ukuze uthole uphawu olungangeni moya. Ukucindezeleka kokuvala kokucindezela isihlalo se-valve kubangela ukuthi izinto ziguquguquke futhi zicindezeleke endaweni elukhuni yengxenye yensimbi yokuhlangana ukuze kuvinjwe noma yikuphi ukuvuza. Ukuvuleka kwezinto eziwuketshezi kuyisisekelo sokuvuza okuncane.

Ukubuka konke kwediski yevalvu: indandatho yokuvala idiski yohlobo lwesiketi. Imodeli yokusetshenziswa iveza indandatho yokuvala idiski yevalvu yohlobo lwesiketi. Isici sayo sokwakheka ukuthi uphawu oluphakathi kwendandatho yokuvala nomzimba wediski yevalvu luwuphawu olunezinhlangothi ezimbili. Ingxenye ende endaweni yokuvala phakathi kwendandatho yokuvala nomzimba wediski yevalvu iyindawo yendiza ye-trapezoidal.

Ukubuka konke kwe-valve core: I-valve core yingxenye ye-valve esebenzisa ukunyakaza komzimba we-valve ukufeza imisebenzi eyisisekelo yokulawula isiqondiso, ukulawula ingcindezi noma ukulawula ukugeleza.

Ingxenye yobuso obungasuswa ku-valve isetshenziselwa ukusekela indawo evaliwe ngokuphelele ye-valve core futhi yakhe i-sealing pair. Ngokuvamile, ububanzi besihlalo se-valve buyi-diameter ephezulu yokugeleza kwe-valve. Isibonelo, ama-valve e-butterfly afika ngezinto ezahlukahlukene zesihlalo. Izinto zesihlalo se-valve zingenziwa ngezinto ezahlukene zerabha, ipulasitiki, kanye nensimbi, njenge: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE, njll.

Izakhiwo zezinto okufanele zicatshangelwe lapho ukhetha isihlalo se-valve esithambile yilezi:
1) Ukuhambisana koketshezi, okuhlanganisa ukuvuvukala, ukulahleka kobulukhuni, ukuvuleka kanye nokuwohloka;
2) Ubulukhuni;
3) Ukuguqulwa okuhlala njalo;
4) Izinga lokululama ngemva kokususa umthwalo;
5) Amandla okunamathela nokucindezela;
6) Ukuguquka kwesimo ngaphambi kokuqhekeka;
7) I-modulus enwebekayo.

Idiski

Idiski yevalvu iyi-core valve, engenye yezingxenye eziyinhloko zevalvu. Ithwala ngqo ingcindezi ephakathi kuvalvu. Izinto ezisetshenziswayo kumele zihambisane nemithethonqubo ethi “Valve Pressure and Temperature Class”.

Izinto ezisetshenziswa kakhulu zifaka okulandelayo:

Ngenxa yezinga lobuchwepheshe lasekhaya lamanje, amafektri ahlukahlukene awalingani, futhi ukuhlolwa kwabasebenzisi kuvame ukuba nobunzima. Ngokusekelwe kokuhlangenwe nakho, kunconywa ukuthi i-PN≤2.5MPa kanye nezinto zevalvu kufanele kube yinsimbi ukuqinisekisa ukuphepha.
4. Insimbi ethambile ye-silicon ephezulu engamelani ne-asidi: ifanelekela imidiya ebolile enengcindezi ejwayelekile ye-PN ≤ 0.25MPa kanye nokushisa okungaphansi kuka-120°C.
5. Insimbi yekhabhoni: ifanelekela izinto ezifana namanzi, umusi, umoya, i-hydrogen, i-ammonia, i-nitrogen kanye nemikhiqizo kaphethiloli enengcindezi ejwayelekile ye-PN ≤ 32.0MPa kanye nokushisa okungu--30 ~ 425°C. Amazinga asetshenziswa kakhulu afaka i-WC1, i-WCB, i-ZG25, insimbi esezingeni eliphezulu engu-20, 25, 30 kanye nensimbi yesakhiwo ephansi engu-16Mn.
6. Ingxube yethusi: ifanelekela amanzi, amanzi olwandle, umoya-mpilo, umoya-mpilo, uwoyela kanye nezinye izinto ezisebenzisa i-PN≤2.5MPa, kanye nezinto ezisebenzisa umusi ezinezinga lokushisa elingu--40~250℃. Izinto ezisetshenziswa kakhulu zihlanganisa i-ZGnSn10Zn2 (ithusi lethini), i-H62, i-Hpb59-1 (ithusi), i-QAZ19-2, i-QA19-4 (ithusi le-aluminium).
7. Ithusi lokushisa eliphezulu: lifanelekela umusi kanye nemikhiqizo kaphethiloli enengcindezi ejwayelekile PN≤17.0MPA kanye nezinga lokushisa ≤570℃. Amabanga asetshenziswa kakhulu afaka phakathi i-ZGCr5Mo, 1Cr5M0, ZG20CrMoV, ZG15Gr1Mo1V, 12CrMoV, WC6, WC9 kanye namanye amabanga. Ukukhetha okukhethekile kumele kuhambisane nengcindezi yevalvu kanye nezilinganiso zokushisa.
8. Insimbi enezinga lokushisa eliphansi, efanelekile kwingcindezi ejwayelekile ye-PN≤6.4Mpa, izinga lokushisa ≥-196℃ i-ethylene, i-propylene, igesi yemvelo encibilikisiwe, i-nitrogen ewuketshezi kanye nezinye izinto ezisetshenziswa kakhulu (izinhlobo ezisetshenziswa kakhulu) zifaka phakathi i-ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 9. Insimbi engagqwali engamelana ne-asidi, efanelekile kwingcindezi ejwayelekile ye-PN≤6.4Mpa, izinga lokushisa ≤200℃ i-nitric acid, i-acetic acid kanye nezinye izinto ezisetshenziswa kakhulu, izinhlobo ezisetshenziswa kakhulu yi-ZG0Cr18Ni9Ti, ZG0Cr18Ni10 , ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti

umongo wevalvu
I-valve core iyingxenye ye-valve esebenzisa ukunyakaza kwayo ukufeza imisebenzi eyisisekelo yokulawula isiqondiso, ukulawula ingcindezi noma ukulawula ukugeleza.

Ukuhlukaniswa
Ngokwemodi yokunyakaza, ihlukaniswe ngohlobo lokujikeleza (45°, 90°, 180°, 360°) kanye nohlobo lokuhumusha (oluqondile, oluqondile).
Ngokwesimo, ngokuvamile ingahlukaniswa ibe yi-spherical (i-ball valve), i-conical (i-plug valve), i-disc (i-butterfly valve, i-gate valve), i-dome-shape (i-stop valve, i-check valve) kanye ne-cylindrical (i-reversering valve).
Ngokuvamile zenziwe ngethusi noma ngensimbi engagqwali, kukhona nepulasitiki, inayiloni, izinto zobumba, ingilazi, njll.
Ingaphakathi levalvu kuvalvu yokunciphisa ingcindezi lingenye yezingxenye eziyinhloko zokulawula ingcindezi.
