MAFUNSO OFUNSIDWA KAWIRIKAWIRI

Kodi njira yoyesera kuthamanga kwa valavu ya chipata ndi iti?

Chipatacho ndi cholimba ngati mutu, ndipo kayendetsedwe ka diski ya valavu kamakhala kolunjika ku mbali ya madzi, ndipo valavu imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, singathe kusinthidwa ndipo throttle imatha kusinthidwa. Valavu ya chipata imatsekedwa kudzera pampando wa valavu ndi diski ya valavu, nthawi zambiri pamwamba pake pamakhala chitsulo kuti chiwonjezere kukana kuwonongeka, monga pamwamba pa 1Cr13, STL6, chitsulo chosapanga dzimbiri ndi zina zotero. Disikiyo ili ndi diski yolimba komanso diski yolimba. Malinga ndi kusiyana kwa diski, mavalavu a chipata amagawidwa m'mavalavu a chipata cholimba ndi mavalavu a chipata cholimba.

njira yoyesera kuthamanga kwa valavu ya chipata

Choyamba, diski imatsegulidwa, kotero kuti kuthamanga mkati mwa valavu kukwera kufika pamtengo wotchulidwa. Kenako, tsekani ram, chotsani nthawi yomweyo valavu ya chipata, yang'anani ngati pali kutuluka kwa madzi mbali zonse ziwiri za diski, kapena lowani mwachindunji choyezera chapakati pamtengo wotchulidwa pa pulagi ya chivundikiro cha valavu, ndikuyang'ana chisindikizo mbali zonse ziwiri za diski. Njira yomwe ili pamwambapa imatchedwa kuthamanga kwapakati. Njira iyi siyoyenera kuyesa chisindikizo cha valavu ya chipata pansi pa mainchesi odziwika a DN32mm.

Njira ina ndikutsegula diski kuti mphamvu ya mayeso a valavu ikwere kufika pamtengo womwe watchulidwa; kenako zimitsani diski, tsegulani mbale yobisika kumapeto kwake, ndikuyang'ana kutuluka kwa nkhope yosindikizira. Kenako bwererani, bwerezani mayesowo mpaka atatsimikizika monga momwe zilili pamwambapa.

Kuyesa kutseka pa kudzaza ndi gasket ya valavu ya pneumatic kuyenera kuchitika mayeso otseka a diski asanayambe.

Mfundo yogwirira ntchito ya actuator yamagetsi
Choyatsira magetsi ndi kuphatikiza kwa choyatsira ndi valavu yowongolera mu dongosolo lowongolera lokha. Ntchito yake mu dongosolo lowongolera lokha ndi kulandira chizindikiro kuchokera kwa chowongolera, komanso chifukwa cha malo ake ndi mawonekedwe ake mu mapaipi a processing, kuti azitha kuyendetsa kayendedwe ka process media kuti azilamulira njira yopangira mkati mwa mulingo wofunikira.
Momwe mungasungire ndikusamalira valavu？
Kuti ntchito yanthawi zonse ipitirire, ndikofunikira kusamalira nthawi zonse ndi kuyang'anira mosamala zida zonse ndi zida.Ma valve a Jinbin zimagwirizana ndi zipangizo ndi zipangizozi
Chifukwa chake, kuti azitha kuyendetsa bwino magawo ofunikira,Ma valve a Jinbiniyenera kuonedwa ngati vuto lalikulu la kukonza ndi kuyang'anira.
Ma Jinbin Valves ndi zinthu zofunika kwambiri zomwe zimalumikiza zipangizozi ndi zipangizozi pamodzi ndikuchita bwino polamulira, motero ziyenera kuganizira mavuto onse osamalira ndi kuyang'anira.
 
Kusamalira kwavalavuali m'ndende
Ngati ma valavu anyamulidwa kupita ku nyumba yosungiramo katundu, woyang'anira ayenera kukhala ndi nthawi yokwanira yosungiramo zinthu, zomwe zimathandiza kuyang'anira ndi kusunga valavu. Woyang'anira ayenera kuyang'ana mosamala zomwe zili mu valavu, kuyang'ana mawonekedwe a valavu, komanso kuthandiza oyang'anira valavuyo asanayesedwe mphamvu yosungiramo ndi kutseka. Kukwaniritsa zofunikira zovomerezeka za valavuyo, zitha kuthandizidwa pa njira zosungiramo zinthu; kulephera kuyeneranso kusungidwa bwino, kuti kuthetsedwe ndi madipatimenti oyenerera.
Pa laibulale ya valavu, kuti mupukute mosamala, yeretsani valavuyo pochotsa madzi ndi fumbi, nthaka yosavuta kuchita dzimbiri, tsinde, pamwamba pake payenera kuphimbidwa ndi wosanjikiza wa mankhwala oletsa dzimbiri kapena kuyika wosanjikiza wa pepala loletsa dzimbiri kuti litetezedwe; njira yolowera ndi yotulutsira valavuyo igwiritsidwe ntchito pogwiritsa ntchito chivundikiro cha pulasitiki kapena pepala la sera kuti litsekedwe, kuti lisalowe m'dothi.
Zinthu ziyenera kusungidwa molingana ndi kukula ndi kukula kwa dongosolo, kutulutsa zinthu m'mashelefu; mavavu akuluakulu amatha kutulutsidwa m'nyumba yosungiramo zinthu pansi, malinga ndi zomwe chitsanzocho chikunena. Zikayikidwa m'zidutswa. Vavu iyenera kuyikidwa moyimirira, osati kutseka pamwamba pa flange komwe kumagwirizana ndi nthaka, koma osaloledwa kusonkhana pamodzi.
Kuti valavu isunge bwino, kuwonjezera pa kufunika kwa nyumba yosungiramo zinthu youma komanso yopuma mpweya, yoyera komanso yoyera, payenera kukhala njira yapamwamba yoyendetsera zinthu zonse zasayansi, yoyang'anira valavu iyenera kusamalidwa nthawi zonse.
Ngati valavu imagwiritsidwa ntchito kwa nthawi yayitali, ngati ikugwiritsidwa ntchito ngati chikwama cha asbestos, chikwamacho chiyenera kuchotsedwa kuchokera ku chikwama cha asbestos, kuti chisawonongeke ndi dzimbiri la mankhwala, komanso kuti chisawonongeke ndi tsinde.
Kupatula pa malamulo ogwiritsira ntchito zoletsa dzimbiri, mafuta odzola, ayenera kusinthidwa kapena kuwonjezeredwa nthawi zonse.
Kodi mfundo yogwirira ntchito ya valavu ya gulugufe ndi iti?

Ntchitoyi ikufanana ndi yavalavu ya mpira, zomwe zimathandiza kuti zitsekedwe mwachangu. Ma valve a gulugufeKawirikawiri amakondedwa chifukwa amakhala otsika mtengo poyerekeza ndi ma valve ena, ndipo ndi opepuka kotero amafunika chithandizo chochepa. Disikiyo imayikidwa pakati pa chitoliro. Ndodo imadutsa mu diskiyo kupita ku actuator kunja kwa valavu. Kuzungulira actuator kumatembenuza diskiyo kukhala yofanana kapena yolunjika ku kayendedwe ka madzi. Mosiyana ndi valavu ya mpira, diskiyo nthawi zonse imakhala mkati mwa kayendedwe ka madzi, kotero imayambitsa kutsika kwa kuthamanga kwa madzi, ngakhale ikatsegulidwa.

Vavu ya gulugufe imachokera ku banja la mavavu otchedwa mavavu ozungulira kotala. Ikugwira ntchito, valavu imatsegulidwa kapena kutsekedwa kwathunthu pamene diski imazunguliridwa kotala. "Gulugufe" ndi diski yachitsulo yoyikidwa pa ndodo. Vavu ikatsekedwa, diski imazunguliridwa kotero kuti imatseka kwathunthu njira yolowera. Vavu ikatsegulidwa kwathunthu, diski imazunguliridwa kotala kotero kuti imalola njira yopanda malire ya madzi. Vavu imathanso kutsegulidwa pang'onopang'ono kuti throttle iyende.

Pali mitundu yosiyanasiyana ya ma valve a gulugufe, iliyonse yosinthidwa kuti igwirizane ndi kupsinjika kosiyanasiyana komanso kugwiritsa ntchito kosiyanasiyana. Valavu ya gulugufe ya zero-offset, yomwe imagwiritsa ntchito kusinthasintha kwa rabara, ili ndi kupsinjika kotsika kwambiri. Valavu ya gulugufe ya double offset, yomwe imagwiritsidwa ntchito m'makina opanikizika pang'ono, imachotsedwa pakati pa mpando wa disc ndi chisindikizo cha thupi (offset one), ndi mzere wapakati wa bore (offset two). Izi zimapangitsa kuti mpando utuluke mu chisindikizo panthawi yogwira ntchito, zomwe zimapangitsa kuti pakhale kukangana kochepa kuposa komwe kumachitika mu kapangidwe ka zero offset ndikuchepetsa chizolowezi chake chotha. Valavu yoyenera kwambiri machitidwe opanikizika kwambiri ndi valavu ya gulugufe ya triple offset. Mu valavu iyi, axis yolumikizirana ndi mpando wa disc imachotsedwa, yomwe imagwira ntchito poletsa kukhudzana pakati pa disc ndi mpando. Pankhani ya ma valve atatu offset, mpando umapangidwa ndi chitsulo kuti uzitha kupangidwa kuti ukhale wotsekedwa bwino ndi thovu likakhudzana ndi disc.

N’chifukwa Chiyani Valve Yanga Ikutuluka Madzi?

Ma valve amatha kutuluka pazifukwa zosiyanasiyana, kuphatikizapo:

  • Valavu ndisichinatsekedwe kwathunthu(monga, chifukwa cha dothi, zinyalala, kapena cholepheretsa china).
  • Valavu ndizowonongekaKuwonongeka kwa mpando kapena chisindikizo kungayambitse kutuluka kwa madzi.
  • Valavu ndisizinapangidwe kuti zitseke 100%Ma valve omwe amapangidwira kuti azilamulira bwino nthawi yogwira ntchito yozungulira sangakhale ndi luso labwino kwambiri loyatsa/kuzima.
  • Valavu ndikukula kolakwikapa ntchitoyi.
Ndi mfundo ziti zomwe ndikufunika kuti ndipange kukula koyenera ndikusankha valavu?
Mfundo zisanu ndi chimodzi zofunika ndizofunikira kuti mupange kukula ndikusankha valavu yotetezera kapena yochepetsera kupanikizika:

  1. Kukula ndi mtundu wa kulumikizana
  2. Kupanikizika kwa Khazikitsani (psig)
  3. Kutentha
  4. Kupanikizika kwa msana
  5. Utumiki
  6. Mphamvu yofunikira
