Ivaluvu ye-Butterfly ye-pneumatic, i-Automatic Control Valve

Izici Zomkhiqizo

Izinzuzo ze-pneumatic soft sealing butterfly valve:

1. Isakhiwo silula, i-coefficient yokumelana nokugeleza incane, izici zokugeleza zivame ukuqondile, futhi akukho mfucumfucu ezogcinwa.
2. Ukuxhumana phakathi kwepuleti uvemvane nesiqu se-valve kusebenzisa isakhiwo esingenaphini, esinqoba indawo yokuvuza yangaphakathi okungenzeka ibe khona.
3. Ihlukaniswe yaba i-wafer yomoya uhlobo lwevalve uvemvane oluvala uphawu oluthambile kanye ne-pneumatic flange elithambile elivala uvemvane ivalve ukuhlangabezana namapayipi ahlukene.
4. Izigxivizo zingashintshwa, futhi ukusebenza kokuvala kunokwethenjelwa futhi kungafinyelela ku-zero ukuvuza kokutywinwa okuphindwe kabili.
5. Impahla yokuvala imelana nokuguga, ukugqwala kanye nempilo ende yesevisi.

Incazelo yepharamitha yevalvu yevemvane ethambile yomoya:

1.Ububanzi begama: DN50～DN1200(mm).
2.Isigaba sokucindezela: PN1.0, 1.6, 2.5MPa.
3.Indlela yokuxhuma: Ukuxhumana kwe-wafer noma i-flange.
Ifomu le-4.Spool: uhlobo lwediski.
Imodi ye-5.Drive: Idrayivu yomthombo womoya, umoya ocindezelwe ongu-5～7bar (ngesondo lesandla).
6.Ibanga lesenzo: 0～90°.
7.Sealing material: zonke izinhlobo zenjoloba, PTFE.
I-8.Isikhathi sokusebenza: Imidiya ehlukahlukene ebolayo, njll. (izinga lokushisa elivamile nokucindezela, izinga lokushisa eliphansi kanye nezikhathi zokucindezela okuphansi).
I-9.Okukhethwa kukho okungeziwe: i-positioner, i-solenoid valve, i-air filter reducer pressure, i-valve yokugcina, i-travel switch, i-valve position transmitter, i-handwheel mechanism, njll.
I-10.Imodi yokulawula: shintsha isilawuli sezindawo ezimbili, i-air-open, i-air-close, i-spring return, uhlobo lokulungiswa okuhlakaniphile (isignali ye-analog ye-4-20mA).

Izici zokusebenza kwevalvu yevemvane eqinile yomoya oqinile:

1. Ukwamukela ukwakheka kwesimiso se-eccentric kathathu, isihlalo se-valve nepuleti le-disc cishe akukho ukungqubuzana lapho kuvulwa futhi ivala, okuthuthukisa impilo yesevisi.
2. Isakhiwo esiyingqayizivele, ukusebenza okuguquguqukayo, ukonga abasebenzi, okulula, okungathinteki ukucindezela okuphezulu noma okuphansi kokusebenza okuphakathi, nokusebenza okuthembekile kokuvala.
3. Ingahlukaniswa nge-wafer ye-pneumatic wafer uhlobo oluqinile lokuvalwa kwe-butterfly valve kanye ne-pneumatic flange eqinile yokuvala uvemvane valve, elungele izindlela ezahlukene zokuxhuma futhi kulula ukuyifaka epayipini.
3. Ukubekwa uphawu kwakhiwe ngamashidi ensimbi athambile futhi aqinile amlaminated, anezinzuzo ezimbili zokuvala uphawu lwensimbi nokufaka uphawu olunwebekayo, futhi kunezici ezinhle kakhulu zokuvala emazingeni okushisa aphansi naphezulu.
5. I-valve ye-butterfly ifakwe idivayisi yokulungisa uphawu.Uma ukusebenza kokuvala kwehla ngemva kokusetshenziswa isikhathi eside, ukusebenza kokuvala kwasekuqaleni kungabuyiselwa ngokulungisa indandatho yokuvala i-disc ukuze isondele esihlalweni se-valve, okuthuthukisa kakhulu impilo yesevisi.

Imingcele yezobuchwepheshe ye-pneumatic hard sealing butterfly valve:

1.Ububanzi begama: DN50～DN1200(mm)
2.Isigaba sokucindezela: PN1.0, 1.6, 2.5, 4.0MPa
3.Indlela yokuxhuma: uhlobo lwe-wafer, uxhumano lwe-flange
Ifomu le-4.Seal: uphawu lwensimbi oluqinile
Imodi ye-5.Drive: idrayivu yomthombo womoya, umoya ocindezelwe 5 ~ 7bar (ngesondo lesandla)
6.Ibanga lesenzo: 0～90°
7.Impahla yomzimba: carbon steel, insimbi engagqwali 304, insimbi engagqwali 316
8.Izimo zokusebenza: amanzi, umusi, uwoyela, ukugqwala kwe-asidi, njll. (ingasetshenziswa ekufakweni komfutho ophezulu kanye nokushisa okuphezulu)
9.Izinga lokushisa: Insimbi ye-Carbon: -29℃～450℃ Insimbi engagqwali: -40℃～450℃
I-10.Imodi yokulawula: imodi yokushintsha (ukulawula ukushintsha kwezikhundla ezimbili, ukuvula umoya, ukuvala umoya), uhlobo lokulungiswa okuhlakaniphile (isignali ye-analog ye-4-20mA), ukubuya kwentwasahlobo.
