Isikhokelo sokufakelwa kweValve yeButterfly

Ufakelo oluchanekileyo lweivalvu yebhabhathaneibalulekile ekusebenzeni kwayo kokuvala kunye nobomi bayo benkonzo. Olu xwebhu luchaza iinkqubo zokufakela, izinto ezibalulekileyo ekufuneka ziqwalaselwe, kwaye lugxininisa umahluko phakathi kweentlobo ezimbini eziqhelekileyo: uhlobo lwe-wafer kunyeiivalvu zebhabhathane ezijijekileyoIivalvu ezifana ne-wafer, ezifakelwa phakathi kweeflanges ezimbini zepayipi kusetyenziswa ii-stud bolts, zinenkqubo yokufakela enzima ngakumbi. Ngokwahlukileyo koko, iivalvu zebhabhathane ezi-flanged ziza neeflanges ezidibeneyo kwaye zibotshelelwa ngqo kwiiflanges zepayipi ezidibanayo, nto leyo eyenza kube lula inkqubo.

Iibholithi zeflange zevalvu yebhabhathane ye-wafer zinde kakhulu. Ubude bazo bubalwa ngolu hlobo: ubukhulu beflange obuyi-2x + ubukhulu bevalvu + ubukhulu be-nut obuyi-2x. Oku kungenxa yokuba ivalvu yebhabhathane ye-wafer ngokwayo ayinazo iiflange. Ukuba ezi bolithi kunye neenati ziyasuswa, imibhobho kumacala omabini evalvu iya kuphazamiseka kwaye ayikwazi ukusebenza ngokuqhelekileyo.

Iivalvu ezineeflange zisebenzisa iibholithi ezimfutshane, ezinobude obuchazwe njengobukhulu beflange obuyi-2x + ubukhulu be-nut obuyi-2x, ukuqhagamshela iiflange zevalve ngqo kwezo zikwipayipi. Inzuzo ebalulekileyo yolu yilo kukuba ivumela ukuba icala elinye liqhawulwe ngaphandle kokuphazamisa ukusebenza kombhobho ochaseneyo.

Eli nqaku liza kwazisa ngokuyintloko imiyalelo yokufakela iivalvu zebhabhathane ze-wafer ngokusebenzisaI-TWS.

Ivalvu yebhabhathane ye-wafer inoyilo olulula, oluncinci, nolukhaphukhaphu oluneendawo ezimbalwa kakhulu. Isebenza ngokujikeleza okukhawulezayo kwe-90°, ivumela ulawulo olulula lokuvula/ukucima kunye nokubonelela ngolawulo oluhle lokuhamba kwamanzi.

I. Imiyalelo Ngaphambi kokufaka iIvalvu yeButterfly yohlobo lweSiliva

1. Ngaphambi kokuba kuqalwe ukufakwa, umbhobho kufuneka ucocwe kuyo nayiphi na into yangaphandle kusetyenziswa umoya ocinezelweyo uze emva koko ucocwe ngamanzi acocekileyo.
2. Jonga ngononophelo ukuba ukusetyenziswa kwevalvu kuyahambelana na nemigangatho yokusebenza kwayo (ubushushu, uxinzelelo).
3. Jonga indlela yevalvu kunye nomphezulu wokuvala ukuba akukho nkunkuma, uze uyisuse ngokukhawuleza.
4. Emva kokukhupha ivalvu, kufuneka ifakwe ngokukhawuleza. Musa ukukhulula naziphi na izikrufu zokubopha okanye iinati kwivalvu ngokungacwangciswanga.
5. Kufuneka kusetyenziswe i-flange ye-butterfly valve ekhethekileyo kwii-wafer butterfly valves.
6. Iivalvu yebhabhathane yombaneingafakwa kwiipayipi nangayiphi na indlela, kodwa ukuze kube lula ukuyilungisa, kuyacetyiswa ukuba ungayifaki ijonge ezantsi.
7. Xa ufaka i-flange ye-butterfly valve, kubalulekile ukuqinisekisa ukuba ubuso be-flange kunye nerabha yokutywina zilungelelaniswe, ii-bolts ziqiniswe ngokulinganayo, kwaye umphezulu wokutywina kufuneka ulingane ngokupheleleyo. Ukuba ii-bolts aziqiniswe ngokulinganayo, kunokubangela ukuba irabha idumbe kwaye ivale idiski, okanye ityhale idiski, nto leyo ebangela ukuvuza kwi-valve stem.

II.Ukufakwa: I-Wafer Butterfly Valve

Ukuqinisekisa ukuba ivalvu yebhabhathane ayivuzi kwaye isebenza ngokukhuselekileyo nangokuthembekileyo, landela le nkqubo yokufaka ingezantsi.

1. Njengoko kubonisiwe, beka ivalvu phakathi kweeflange ezimbini ezifakwe kwangaphambili, uqinisekise ukuba imingxunya yebholithi ilungelelaniswe ngokufanelekileyo.

2. Faka ngobunono iibholiti ezine kunye neenati kwimingxunya yeflange, uze uziqinise kancinci iinati ukuze ulungise ukuthamba komphezulu weflange;

3. Sebenzisa i-spot welding ukuze uqinise i-flange kumbhobho.

4. Susa ivalvu;

5. Yitshixe ngokupheleleyo iflengi kwipayipi.

6. Faka ivalvu kuphela emva kokuba ijoyinti edibeneyo ipholile. Qinisekisa ukuba ivalvu inendawo eyaneleyo yokuhamba ngaphakathi kwiflange ukuthintela umonakalo kwaye idiski yevalvu ingavuleka ukuya kuthi ga kwinqanaba elithile.

7. Lungisa indawo yevalvu uze uqinise iibholithi ezine (lumka ungaqini kakhulu).

8. Vula ivalvu ukuqinisekisa ukuba idiski iyakwazi ukuhamba ngokukhululekileyo, uze uyivule kancinci idiski.

9. Sebenzisa ipatheni enqamlezileyo ukuqinisa zonke iinati.

10. Qinisekisa kwakhona ukuba ivalvu ingavuleka kwaye ivale ngokukhululekileyo. Qaphela: Qinisekisa ukuba idiski yevalvu ayichukumisi umbhobho.

Ukuze iivalvu zebhabhathane ze-wafer zisebenze ngokukhuselekileyo nangokungavuzi, landela le migaqo:

• Phatha Ngononophelo: Gcina ivalvu ngokukhuselekileyo kwaye uphephe ukungqubana.
• Lungelelanisa ngokuchanekileyo: Qinisekisa ukuba iflegi ilungelelaniswe ngokugqibeleleyo ukuze kuthintelwe ukuvuza.
• Musa Ukuyiqhaqha: Nje ukuba ifakiwe, ivalvu akufuneki iqhaqhwe ebaleni.
• Faka Izixhasi Ezihlala Zihleli: Khusela ivalvu ngezixhasi ekufuneka zihlale zisendaweni yazo.

I-TWSibonelela ngeevalvu zeebhabhathane ezikumgangatho ophezulu kunye nezisombululo ezipheleleyo zeivalvu yesango, ivalvu yokujongakunyeiivalvu zokukhupha umoyaQhagamshelana nathi ngazo zonke iimfuno zakho zevalvu.
