Intshayelelo kwiivalvu zeButterfly

Iivalve zebhabhathane

Ivalve yeButterfly yivalve ejikelezayo ejikelezayo yekota, esetyenziselwa ukumisa, ukulawula, kunye nokuqalisa ukuhamba.

Iivalve zebhabhathane zilula kwaye zikhawuleza ukuzivula. Ukujikeleza kwe-90 ° kwesiphatho kunika ukuvala ngokupheleleyo okanye ukuvulwa kwevalve. Iivalve ezinkulu zeButterfly zihlala zinento ebizwa ngokuba yi-gearbox, apho ivili lesandla ngamagiya lidityaniswe nesiqu. Oku kwenza lula ukusebenza kwevalve, kodwa ngeendleko zesantya.

Iintlobo zeevalvu zebhabhathane

Iivalve zebhabhathane zinomzimba omfutshane ojikelezayo, idiski engqukuva, izihlalo zentsimbi ukuya kwentsimbi okanye ezithambileyo, iibheringi zeshafti eziphezulu nezisezantsi, kunye nebhokisi yokuhlohla. Ukwakhiwa komzimba wevalve yeButterfly kuyahluka. Uyilo oluqhele ukusetyenziswa luhlobo lwewafer olungena phakathi kweeflange ezimbini. Olunye uhlobo, i-lug wafer design, lubanjwa phakathi kweeflange ezimbini ngeebholiti ezidibanisa iiflange ezimbini nezidlula kwimingxuma engaphandle kwevalve. Iivalve zebhabhathane ziyafumaneka neziphelo eziphothiweyo, ezicudisiweyo kunye neempundu, kodwa azisoloko zisetyenziswa.

Iivalvu zebhabhathane zineengenelo ezininzi ngaphezulu kwesango, iglowubhu, iplagi, kunye neevalvu zebhola, ngakumbi kusetyenziso lwevalvu enkulu. Ukonga ubunzima, indawo, kunye neendleko zezona zibonelelo zicacileyo. Iindleko zokulondolozwa zihlala ziphantsi kuba kukho inani elincinci leendawo ezihambayo kwaye akukho zipokotho zokubamba ulwelo.

Iivalvu zebhabhathane zikulungele ngokukodwa ukuphatha imiqukuqelo emikhulu yolwelo okanye iigesi eziphantsi kakhulu zoxinzelelo kunye nokuphatha uludaka okanye ulwelo ngezixa ezikhulu zezinto eziqinileyo ezimisiweyo.

Iivalve zebhabhathane zakhiwe kumgaqo wedamper yombhobho. Isiqalelo solawulo lokuqukuqela yidisk emalunga nedayamitha efanayo nedayamitha yangaphakathi yombhobho odibanayo, ojikeleza nokuba kwi-axis ethe nkqo okanye ethe tye. Xa idiski ilele ngokunxuseneyo nokuqhutywa kwemibhobho, ivalve ivulwe ngokupheleleyo. Xa idiski isondela kwindawo ye-perpendicular, ivalve ivaliwe. Izikhundla eziPhakathi, ngeenjongo ze-throttling, zinokukhuselwa kwindawo ngezixhobo zokuvala i-handle-locking.

Butterfly valve Seat Construction

Ukumiswa kokuhamba kwenziwa ngokutywinwa kwediski yevalvu ngokuchasene nesihlalo esingaphakathi komda weperipheri yevalvu yomzimba. Iivalvu ezininzi zeButterfly zinesihlalo se-elastomeric apho idisk itywina khona. Ezinye iivalve zeButterfly zinolungiselelo lweringi yokutywina esebenzisa i-clamp-ring kunye ne-backing-ring kwiringi yerabha ebomvu equkuqelayo. Olu luyilo luthintela ukukhutshwa kwe-O-rings.

Kuyilo lwangaphambili, idiski yesinyithi yayisetyenziselwa ukutywina ngokuchasene nesihlalo sentsimbi. Eli lungiselelo alizange libonelele ngokuvalwa okuvuzayo, kodwa libonelele ngokuvalwa okwaneleyo kwezinye izicelo (oko kukuthi, iintambo zokuhanjiswa kwamanzi).

Butterfly valve Ukwakhiwa komzimba

Ukwakhiwa komzimba kwevalve yebhabhathane kuyahluka. Olona qoqosho luhlobo lwe-wafer olungena phakathi kweeflange zemibhobho emibini. Olunye uhlobo, i-lug wafer design, ibanjwa phakathi kweeflenge zemibhobho emibini ngeebholiti ezidibanisa iiflange ezimbini nezidlula kwimingxuma engaphandle kwevalve. Iivalvu zebhabhathane ziyafumaneka ezineziphelo eziqhelekileyo eziphothiweyo zokubopha iiflange zemibhobho, nakwisiphelo solwakhiwo olunemisonto.

Isihlalo seDiski kunye neSithi sevalve yebhabhathane

Isiqu kunye nediski yevalve yebhabhathane ziziqwenga ezahlukeneyo. Idiski iyadika ukufumana isiqu. Iindlela ezimbini zisetyenziselwa ukukhusela idiski kwi-stem ukuze idiski ijikeleze njengoko i-stem ijika. Kwindlela yokuqala, i-disk ibhokile kwaye ikhuselekile kwisiqu ngeebholiti okanye izikhonkwane. Enye indlela ibandakanya ukukruqula idisk njengangaphambili, emva koko ukubumba umphezulu wesiqu ukuze ulingane nesiqu esiphindwe kabini okanye esimilise okwehex. Le ndlela ivumela idiski ukuba "ihambe" kwaye ifune indawo yayo esihlalweni. Ukutywinwa okufanayo kuyafezekiswa kwaye izibophelelo zesiqu zangaphandle ziyacinywa. Le ndlela yokuhlanganisa inenzuzo kwimeko yeediski ezifihliweyo kunye nezicelo ezinobungozi.

Ukuze i-disk ibanjwe kwindawo efanelekileyo, isiqu kufuneka sidlulele ngaphaya komzantsi wediski kwaye singene kwi-bushing ephantsi kwe-valve body. I-bushings enye okanye ezimbini ezifanayo zikwindawo ephezulu yesiqu ngokunjalo. Ezi bushings kufuneka zixhathise kumajelo osasazo aphathwayo okanye atywinwe ukuze amajelo eendaba ezonakalisayo angakwazi ukudibana nawo.

Ukutywinwa kwe-Stem kufezekiswa ngokupakisha kwibhokisi yokufaka eqhelekileyo okanye ngokutywinwa kwe-O-ring. Abanye abavelisi bevalvu, ngakumbi abo bazingcaphephe ekuphatheni izinto ezidlekayo, babeka isikhondo sokutywina ngaphakathi kwevalvu ukuze kungabikho nto iphathwayo inokudibana nesikhondo sevalvu. Ukuba kuqeshwe ibhokisi yokugxumeka okanye i-O-ring yangaphandle, ulwelo oludlula kwivalve luya kudibana nesiqu sevalve.

Ayilunganga
I-Disc kwindawo evaliweyo kunye neeGaskets ezifakiwe
phakathi kwevalve kunye neeflange zokukhwelana

Kulungile
Akukho gaskets flange esetyenziswa kunye Disc kwi
indawo ephantse ivaliwe.

Omnye umyalelo wofakelo ovela kumthengisi weevalvu zeButterfly:

ISILUMKO
Ezi gaskets zilandelayo kufuneka zisetyenziselwe ukufakwa kweevalvu kwimibhobho.

• Uhlobo lweGasket
  Igasket ye-PTFE eyomeleziweyo (igasket enebhatyi, i-Spiral Wound gasket okanye iMetal gasket ayinakufakwa.)
• Ubungakanani beGasket
  Imilinganiselo ye-gasket kufuneka ihambelane ne-ASME B16.21. (Ubuncinane bobunzima begasket yi-3mm.)

Iivalvu azinakufakelwa kwiindawo zokubeka. Ivalve kufuneka ifakwe ngokwentolo, ibonelelwe kwicala le-flange yomqhubi wokuxhoma. Utolo kufuneka lukhombe ukusuka kwicala loxinzelelo oluphezulu ukuya kwicala elisezantsi loxinzelelo kwindawo evaliweyo yevalve.

Ngoko ke, kuyacetyiswa ukuba ulandele imiyalelo yomthengisi wevalve yeButterfly!

Ukunqanda iingxaki ngeevalvu zeButterfly

Uninzi lwazo zonke iingxaki ngeevalvu zeButterfly ebaleni zinxulumene ngokuthe ngqo neenkqubo zofakelo ezingekho mgangathweni. Ngenxa yesi sizathu, kububulumko ukuqwalasela eyona ndlela-ukusebenza xa ubeka umbhobho-umsebenzi kunye nokufaka i-valve ngokwayo.

Isihlalo esikwivalve yebhabhathane ekwaziyo ukumelana nesixhaso sikholisa ukunabela kubuso omabini bevalvu. Ngenxa yoko, akukho gaskets zifunekayo njengoko ezi zihlalo zisebenza umsebenzi we-gasket. Isixhobo sokuhlala esidlula kubuso sicinezelwe ngexesha lofakelo kwaye sigeleza sisiya kumbindi wesihlalo sevalve. Naluphi na utshintsho kolu lungelelwaniso ngenxa yofakelo olungafanelekanga luchaphazela ngokuthe ngqo ukulinganiswa koxinzelelo kunye nokuhlalisa / ukukhupha iitorque.

Ngokungafaniyo neentlobo ezininzi zevalve, idiski yevalve yeButterfly idlulela ngaphaya kobuso bomzimba wevalvu kwii-engile ezinikiweyo zokuvula (thi, 30° okanye ngaphezulu) xa ifakwe phakathi kweeflange. Ngoko ke, kubaluleke kakhulu ngaphambi kokufaka ukuqinisekisa ukuba i-disc iyakwazi ukujika ngokukhululekile kwaye ifake iiflange kunye nomsebenzi wombhobho.

Ukuthunyelwa kunye noGcino

• Beka iidiski kwi-10% evulekileyo ukwenzela ukuba bangabikho.
• Ubuso bevalve nganye kufuneka bugqunywe ukunqanda umonakalo kubuso besihlalo, idiskhi edge, okanye ngaphakathi kwevalvu.
• Gcina ngaphakathi endlwini, ngakumbi kumaqondo obushushu aphakathi kwe-5°C kunye ne-30°C.
• Vula kwaye uvale iivalvu rhoqo kwiinyanga ezi-3.
• Iinqanawa kunye neevalvu zokugcina ukuze kungabikho mthwalo onzima osetyenziswa kwimizimba.

Indawo yeValve

• Iivalvu zebhabhathane kufuneka zifakwe ukuba kuyenzeka ubuncinci bemibhobho ye-6 yeedamitha ukusuka kwezinye izinto zomgca, okt ingqiniba, iimpompo, iivalvu, njl.njl. Ngamanye amaxesha oku akunakwenzeka, kodwa kubalulekile ukufikelela umgama omde kangangoko kunokwenzeka.
• Apho ivalve yeButterfly iqhagamshelwe kwivalve yokutshekisha okanye impompo, gcina isithuba esaneleyo phakathi kwazo ukuqinisekisa ukuba idiski ayiphazamisi isixhobo esisecaleni.

Ukuqhelaniswa neValve

Njengomthetho wobhontsi, iivalvu zeButterfly zifakwe kunye nesiqu kwindawo ethe nkqo kunye ne-actuator ifakwe ngokuthe nkqo phezu kwayo, nangona kunjalo, kukho izicelo apho isiqu kufuneka sithe tyaba. Ifayile ye.pdf ingezantsi ikuxelela kutheni isikhondo somtimes kufuneka sibekwe ngokuthe tye.
