Kodi njira yoyezera kuthamanga kwa valve pachipata ndi iti?

Chipata ndi mutu wamphongo, ndi kayendedwe ka valavu chimbale ndi perpendicular kwa malangizo a madzimadzi, ndi valavu akhoza kutseguka mokwanira ndi kutsekedwa kwathunthu, sangathe kusinthidwa ndi throttle.Valve yachipata imasindikizidwa pampando wa valve ndi diski ya valve, nthawi zambiri malo osindikizira amakwera pamwamba pazitsulo kuti awonjezere kukana, monga 1Cr13, STL6, chitsulo chosapanga dzimbiri ndi zina zotero. elastic disc.Malingana ndi kusiyana kwa diski, ma valve a pakhomo amagawidwa kukhala ma valve olimba a chipata ndi ma valve otsekemera.

njira yoyezera kuthamanga kwa valve pachipata

Choyamba, diski imatsegulidwa, kotero kuti kupanikizika mkati mwa valve kumakwera mtengo wotchulidwa.Kenako, tsekani nkhosa yamphongo, nthawi yomweyo chotsani valavu yachipata, fufuzani ngati pali kutayikira kumbali ziwiri za diski, kapena lowetsani mwachindunji sing'anga yoyesera ku mtengo wotchulidwa pa pulagi ya chivundikiro cha valve, ndipo fufuzani chisindikizo kumbali zonse ziwiri. wa disc.Njira yomwe ili pamwambayi imatchedwa kuthamanga kwapakati.Njirayi siyoyenera kuyesa chisindikizo cha valavu ya chipata pansi pa DN32mm mwadzina.

Njira ina ndikutsegula chimbale kuti chiwongolero cha kuyesa kwa valve kukwera pamtengo wotchulidwa;Kenako zimitsani chimbale, tsegulani mbale yakhungu kumbali imodzi, ndikuyang'ana kutuluka kwa nkhope yosindikizira.Kenako bwererani, bwerezani mayesowo mpaka muyenerere monga pamwambapa.

Kuyesa kusindikiza pa kudzazidwa ndi gasket ya valavu ya pneumatic iyenera kuchitidwa musanayambe kuyesa chisindikizo cha disc.

Mfundo ntchito ya magetsi actuator
Electric actuator ndi kuphatikiza kwa actuator ndi valavu yowongolera mu makina owongolera okha.Udindo wake mu dongosolo kulamulira basi ndi kuvomereza chizindikiro kwa owongolera, ndi udindo wake ndi makhalidwe mu ndondomeko mapaipi, kulamulira otaya njira TV kulamulira ndondomeko kupanga mkati mwa kofunika.
Momwe mungasungire ndi kusamalira vavu?
Kuti ntchito yanthawi zonse ikhale yokhazikika, ndikofunikira kuti pakhale kukonza nthawi zonse ndikuwongolera mosamala zida zonse ndi zida.Ma valve a Jinbin amalumikizidwa ndi zida ndi zida izi
Kusewera machitidwe ake owongolera magawo ofunikira, chifukwa chake,Ma valve a Jinbinziyenera kuganiziridwa kuti ndizovuta zonse zosamalira ndi kusamalira.
Valve ya JinbinKusamalira
Ma valve a Jinbin ndi zigawo zofunika kwambiri zomwe zimagwirizanitsa zida ndi zipangizozi pamodzi ndikusewera momwe zimagwirira ntchito, choncho ziyenera kuganizira za kusamalira ndi kuyang'anira.
 
Kukonzekera kwavalavum'ndende
Kuyendetsa ma valve mu nyumba yosungiramo katundu, woyang'anira ayenera kukhala panthawi yake yosungiramo zinthu, zomwe zimathandiza kuyang'anitsitsa ndi kusunga valve.Woyang'anira ayenera kuyang'ana mosamala mafotokozedwe a chitsanzo cha valve, ayang'ane maonekedwe a khalidwe la valve, ndikuthandizira oyang'anira a valve musanayambe kuyesa mphamvu zosungirako ndi kusindikiza kusindikiza.Kukumana ndi zovomerezeka zovomerezeka za valve, zitha kugwiridwa ndi njira zosungira;kulepherako kuyeneranso kusungidwa bwino, kuti kuthetsedwe ndi madipatimenti oyenera.
Pa laibulale ya valavu, kupukuta mosamala, kuyeretsa valavu mu kayendedwe ka madzi ndi fumbi dothi, mosavuta dzimbiri pamwamba, tsinde, kusindikiza pamwamba ayenera yokutidwa ndi wosanjikiza odana ndi dzimbiri wothandizira kapena muiike wosanjikiza anti - Pepala la dzimbiri lizitetezedwa;cholowetsa ma valve ndi njira zotulutsiramo kugwiritsa ntchito chivundikiro cha pulasitiki kapena pepala la sera kuti litsekeke, kuti musalowe mudothi.
Zosungira ziyenera kuchitidwa molingana ndi kukula ndi kukula kwa dongosolo, kutulutsa pazitsulo;mavavu lalikulu akhoza kutulutsidwa mu nyumba yosungiramo katundu pansi, malinga ndi specifications chitsanzo Kuikidwa mu zidutswa.Vavu iyenera kuyikidwa mowongoka, osati kukhudzana ndi malo osindikizira a flange ndi pansi, koma osaloledwa kuyika pamodzi.
Kuti valavu ikhale yabwino, kuwonjezera pakufunika kowuma ndi mpweya wabwino, nyumba yosungiramo zinthu zoyera ndi zoyera, payenera kukhala ndondomeko yapamwamba, yoyendetsera sayansi yoyang'anira zonse zomwe valve iyenera kuyang'aniridwa nthawi zonse.
Kwa nthawi yayitali yogwiritsira ntchito valavu, ngati ntchito ya asibesitosi ikugwiritsidwa ntchito, iyenera kukhala ya asibesitosi yonyamula kuchokera ku kalata yonyamula kuchotsedwa, kuti mupewe dzimbiri zamagetsi zamagetsi, kuwonongeka kwa tsinde.
Kuposa makonzedwe a ntchito zoletsa dzimbiri, lubricant, ayenera nthawi zonse m'malo kapena kuwonjezeredwa.
Kodi valavu ya butterfly ndi chiyani?

Ntchito ikufanana ndi ya avalavu ya mpira, zomwe zimalola kutseka msanga. Mavavu a butterflynthawi zambiri amakondedwa chifukwa amawononga ndalama zochepa kuposa ma valve ena, ndipo ndi opepuka kotero amafunikira chithandizo chochepa.Chimbalecho chili pakatikati pa chitoliro.Ndodo imadutsa mu disc kupita ku actuator kunja kwa valve.Kuzungulira kwa actuator kutembenuza chimbalecho kukhala chofanana kapena chokhazikika pakuthamanga.Mosiyana ndi valavu ya mpira, diski imakhalapo nthawi zonse, choncho imayambitsa kutsika kwapakati, ngakhale itatseguka.

Vavu yagulugufe imachokera ku banja la ma valve otchedwa quarter-turn valves.Pogwira ntchito, valavu imatsegulidwa kwathunthu kapena yotsekedwa pamene diski imazungulira kotala."Gulugufe" ndi diski yachitsulo yomwe imayikidwa pa ndodo.Vavu ikatsekedwa, diski imatembenuzidwa kotero kuti imatsekereza njirayo.Vavu ikatsegulidwa kwathunthu, chimbalecho chimazunguliridwa kozungulira kotala kotero kuti imalola kuti madzi azitha kuyenda mopanda malire.Valve imathanso kutsegulidwa pang'onopang'ono kuti throttle ikuyenda.

Pali mitundu yosiyanasiyana ya ma valve agulugufe, iliyonse yosinthidwa kuti igwirizane ndi zovuta zosiyanasiyana komanso kagwiritsidwe ntchito kosiyana.Vavu yagulugufe ya zero-offset, yomwe imagwiritsa ntchito kusinthasintha kwa mphira, imakhala ndi mphamvu yotsika kwambiri.Valavu yagulugufe yogwira ntchito kwambiri, yomwe imagwiritsidwa ntchito pamakina apamwamba kwambiri, imachotsedwa pakatikati pa mpando wa disc ndi chisindikizo cha thupi (chochotsa chimodzi), ndi mzere wapakati wa bore (offset two).Izi zimapanga chochita cha cam panthawi yogwira ntchito kukweza mpando kuchokera pa chisindikizo zomwe zimapangitsa kuti pakhale mikangano yocheperako kuposa momwe imapangidwira pamapangidwe a zero offset ndikuchepetsa chizolowezi chake kuvala.Vavu yoyenera kwambiri pamakina othamanga kwambiri ndi valavu yamagulugufe atatu.Mu valavu iyi chimbale mpando kukhudzana axis ndi offset, amene amachita pafupifupi kuthetsa kutsetsereka kukhudzana pakati pa chimbale ndi mpando.Pankhani ya katatu offset mavavu mpando wapangidwa ndi zitsulo kotero kuti akhoza machined monga kukwaniritsa kuwira zolimba kutseka-kutseka pamene anakumana ndi chimbale.

Chifukwa Chiyani Vavu Yanga Ikutuluka?

Mavavu amatha kutuluka pazifukwa zosiyanasiyana, kuphatikiza:

  • Valve ndiosatsekedwa kwathunthu(mwachitsanzo, chifukwa cha litsiro, zinyalala, kapena kutsekereza kwina).
  • Valve ndizowonongeka.Kuwonongeka kwa mpando kapena chisindikizo kungayambitse kutayikira.
  • Valve ndisichinapangidwe kutseka 100%.Mavavu omwe amapangidwira kuti aziwongolera bwino panthawi yopumira sangakhale ndi mphamvu zoyatsa / kuzimitsa.
  • Valve ndikukula kolakwikaza polojekitiyi.
Kodi ndikufunika chiyani kuti ndisakulire bwino ndikusankha vavu?
Zidziwitso zisanu ndi chimodzi zofunika kukula ndikusankha valavu yotetezera kapena kupanikizika:

  1. Kukula kwa kulumikizana ndi mtundu
  2. Set pressure (psig)
  3. Kutentha
  4. Kupanikizika kwa msana
  5. Utumiki
  6. Kuthekera kofunikira
