Isikhokelo soFakelo lweValve yeButterfly

Ufakelo oluchanekileyo lwe-aivelufa butterflyibalulekile ekusebenzeni kwayo kokutywinwa kunye nobomi benkonzo. Olu xwebhu lunika iinkcukacha ngeenkqubo zofakelo, iingqwalasela eziphambili, kwaye luqaqambisa umahluko phakathi kwezi ntlobo zimbini ziqhelekileyo: isitayile se-waferiivalve zebhabhathane ezinecala. Iivalvu zesimbo se-Wafer, ezifakwe phakathi kweeflange zemibhobho emibini kusetyenziswa iibholiti ze-stud, zinenkqubo yokufakela entsonkothileyo ngakumbi. Ngokwahlukileyo koko, iivalve zebhabhathane ezijingiwe ziza neeflange ezidityanisiweyo kwaye zibotshelelwe ngokuthe ngqo kwiiflange zemibhobho yokukhwelana, nto leyo eyenza inkqubo ibe lula.

Iibholithi zeflange zevalve yebhabhathane yebhabhathane zinde ngokwentelekiso. Ubude babo bubalwa ngolu hlobo: 2x flange ubukhulu + valve ubukhulu + 2x nut ubukhulu. Oku kungenxa yokuba ivalufa yebhabhathane ngokwayo ayinazo iiflange. Ukuba ezi bholiti kunye namantongomane zisusiwe, imibhobho emacaleni omabini evalvu iya kuphazamiseka kwaye ayikwazi ukusebenza ngokuqhelekileyo.

Iivalvu ezijikethekileyo zisebenzisa iibholiti ezimfutshane, ezinobude obuchazwa njenge-2x flange ubukhulu + 2x ubukhulu bamantongomane, ukudibanisa iiflange zevalve ngokuthe ngqo kwezo zikwimibhobho. Inzuzo ebalulekileyo yolu yilo kukuba ivumela ukuba elinye icala linqanyulwe ngaphandle kokuphazamisa ukusebenza kombhobho ochaseneyo.

Eli nqaku liza kwazisa ubukhulu becala imiyalelo yofakelo yeevalvu zebhabhathane ngeTWS.

Ivalve yebhabhathane ye-wafer ine-design elula, ehlangeneyo, kunye nekhaphukhaphu enamalungu ambalwa kakhulu. Isebenza ngokukhawuleza kwe-90 ° ukujikeleza, okwenza kube lula ukucima / ukuvala ulawulo kunye nokubonelela ngolawulo oluhle kakhulu lokuhamba.

I. Imiyalelo Ngaphambi kokufaka iIvalufa yebhabhathane yohlobo lweWafer

1. Phambi kokuba ufakelo luqale, umbhobho kufuneka ucocwe kuyo nayiphi na into yangaphandle kusetyenziswa umoya ocinezelweyo kwaye emva koko ucocwe ngamanzi acocekileyo.
2. Khangela ngononophelo ukuba ukusetyenziswa kwevalve kuhambelana neenkcukacha zayo zokusebenza (ubushushu, uxinzelelo).
3. Qwalasela indlela yevalvu kunye nomphezulu otywiniweyo wenkunkuma, kwaye uyisuse kwangoko.
4. Emva kokukhupha, i-valve kufuneka ifakwe ngokukhawuleza. Musa ukukhulula naziphi na izikrufu zokuqhoboshela okanye amandongomane kwivalve ngokungenasizathu.
5. Ivalve yebhabhathane ezinikeleyo kufuneka isetyenziswe kwiivalvu zohlobo lwebhabhathane.
6. Iivelufa butterfly yombaneinokufakwa kwimibhobho kuyo nayiphi na i-angle, kodwa ukugcinwa lula, kuyacetyiswa ukuba ungayifaki phezulu.
7. Xa ufaka i-flange ye-butterfly valve, kubalulekile ukuqinisekisa ukuba ubuso be-flange kunye nerubha yokutywina ihambelana, iibholiti ziqiniswe ngokulinganayo, kwaye indawo yokutywina kufuneka ifane ngokupheleleyo. Ukuba iibholiti aziqiniswanga ngokufanayo, kunokubangela ukuba irabha ivuthe kwaye idibanise idiski, okanye ityhale kwidiski, okukhokelela ekuvuzeni kwisiqu sevalve.

II.Ukufakela: Ivalufa yeBhavabhaka yeWafer

Ukuqinisekisa ukutywinwa okungavuziyo kunye nokusebenza okukhuselekileyo, okuthembekileyo kwevalve yebhabhathane, landela inkqubo yofakelo engezantsi.

1. Njengoko kubonisiwe, faka i-valve phakathi kwee-flanges ezimbini ezifakwe ngaphambili, uqinisekise ukuba imingxuma yebholithi ihambelana ngokufanelekileyo.

2. Faka ngobumnene izibini ezine zeebholiti kunye namantongomane kwimingxuma ye-flange, kwaye uqinise kancinane amantongomane ukuze ulungise ukukhanya kwendawo yeflange;

3. Sebenzisa i-spot welding ukukhusela i-flange kumbhobho.

4. Khupha ivalve;

5. Weld ngokupheleleyo flange kumbhobho.

6. Faka ivalve kuphela emva kokuba ijoyinti edityanisiweyo ipholile. Qinisekisa ukuba ivalve inendawo eyaneleyo yokuhamba ngaphakathi kweflange ukukhusela umonakalo kunye nokuba idiski yevalve inokuvuleka ukuya kwinqanaba elithile.

7. Lungisa indawo yevalve kwaye uqinise izibini ezine zeebholiti (qaphela ukuba ungagqithisi).

8. Vula ivalve ukuqinisekisa ukuba idiski iyakwazi ukuhamba ngokukhululekileyo, emva koko uvule kancinci idiski.

9. Sebenzisa ipateni yomnqamlezo ukuqinisa onke amandongomane.

10. Qinisekisa kwakhona ukuba isivalo sinokuvula kwaye sivale ngokukhululekileyo. Qaphela: Qinisekisa ukuba idiski yevalve ayiwuchukumisi umbhobho.

Ukusebenza okukhuselekileyo, okungavuziyo kweevalvu zebhabhathane, bambelela kule migaqo:

• Bamba ngononophelo: Gcina ivalve ngokukhuselekileyo kwaye uphephe iimpembelelo.
• Lungelelanisa ngokuchanekileyo: Qinisekisa ulungelelwaniso olugqibeleleyo lweflange ukuthintela ukuvuza.
• Musa Ukuqhaqha: Nje ukuba ifakwe, ivalve kufuneka ingaqhathwa ebaleni.
• Faka iiNkxaso eziSisigxina: Khusela i-valve kunye nezixhaso ezimele zihlale kwindawo.

TWSibonelela ngeevalvu zebhabhathane ezikumgangatho ophezulu kunye nezisombululo ezibanzi zeivalve yesango, khangela ivalve, kwayeiivalve zokukhupha umoya. Qhagamshelana nathi ngazo zonke iimfuno zakho zevalvu.
