Indlela yokufaka ivalvu yebhola?

Indlela yokufaka ivalvu yebhola kufuneka imiselwe ngokohlobo lwevalvu yebhola, iimpawu zombhobho kunye nendawo ethile yokusetyenziswa. Nazi amanyathelo okufakela ngokubanzi kunye namanyathelo okhuseleko:

Okokuqala, lungiselela ngaphambi kokufakwa

1. Qinisekisa imeko yombhobho: qinisekisa ukuba umbhobho ngaphambi nasemva kwevalvu yebhola ulungile, kwaye umbhobho kufuneka ube yi-coaxial, kwaye umphezulu wokutywina weeflanges ezimbini kufuneka ulingane. Umbhobho kufuneka ukwazi ukumelana nobunzima bevalvu yebhola, kungenjalo kufuneka kulungiselelwe inkxaso efanelekileyo kumbhobho.

2. Ukucoca imibhobho kunye neevalvu zebhola: susa iivalvu zebhola kunye neepayipi, susa ioyile, i-welding slag kunye nazo zonke ezinye izinto ezingcolileyo ezikwipayipi, kwaye ucoce ngaphakathi nangaphandle kwevalvu yebhola ukuqinisekisa ukuba akukho zinto zingcolileyo kunye neoyile.

3. Jonga ivalvu yebhola: jonga uphawu lwevalvu yebhola ukuqinisekisa ukuba ivalvu yebhola ayiguquki. Vula kwaye uyivale ngokupheleleyo ivalvu yebhola izihlandlo ezininzi ukuqinisekisa ukuba isebenza kakuhle.

Okwesibini, amanyathelo okufakela

1. I-flange yoqhagamshelo:

- Susa ukhuseleko kwiiflanges ezidibanisayo kuzo zombini iziphelo zevalvu yebhola.

- Lungelelanisa i-flange yevalvu yebhola ne-flange yombhobho, uqinisekise ukuba imingxunya ye-flange ihambelana.

- Sebenzisa iibholithi zeflange ukudibanisa ivalvu yebhola kunye nombhobho ngokuqinileyo, kwaye uqinise iibholithi nganye nganye ukuqinisekisa uqhagamshelo oluqinileyo.

2. Faka i-gasket:

- Faka ubungakanani obufanelekileyo besitywini okanye ufake ii-gaskets zokutywina kumphezulu wokutywina phakathi kwevalvu yebhola kunye nombhobho ukuqinisekisa ukuba umphezulu wokutywina uthambile kwaye usebenza kakuhle.

3. Qhagamshela isixhobo sokusebenza:

- Qhagamshela intloko yesiqu sevalvu yevalvu yebhola kwisixhobo sokusebenza (njengesiphatho, i-gearbox okanye i-pneumatic drive) ukuqinisekisa ukuba isixhobo sokusebenza sinokusijikelezisa kakuhle isiqu sevalvu.

4. Jonga ufakelo:

- Emva kokuba ufakelo lugqityiwe, jonga ukuba ukufakelwa kwevalvu yebhola kuyahlangabezana na neemfuno, ingakumbi jonga ukuba uqhagamshelo lweflange luqinile na kwaye ukusebenza kokutywina kulungile.

- Zama ukusebenzisa ivalvu yebhola izihlandlo ezininzi ukuqinisekisa ukuba ivalvu iyakwazi ukuvula nokuvala kakuhle.

Okwesithathu, amanyathelo okufaka

1. Indawo yokufaka: Ivalvu yebhola kufuneka ifakwe kumbhobho othe tye, ukuba kufuneka ifakwe kumbhobho othe nkqo, isiqu sevalvu kufuneka sijonge phezulu, ukuze kuthintelwe ukuba umongo wevalvu ucinezelwe lulwelo olusesihlalweni, nto leyo ebangela ukuba ivalvu yebhola ingavalwa ngokuqhelekileyo.

2. Indawo yokusebenza: Shiya indawo eyaneleyo ngaphambi nasemva kwevalvu yebhola ukuze kube lula ukusebenza nokugcinwa kwevalvu yebhola.

3. Kuphephe umonakalo: Ngexesha lenkqubo yokufaka, qaphela ukuba ivalvu yebhola ayichaphazeleki okanye ikrwelwe, ukuze ingonakalisi ivalvu okanye ichaphazele ukusebenza kwayo kokutywina.

4. Ukusebenza kokutywina: Qinisekisa ukuba umphezulu wokutywina ugudile kwaye ucocekile, kwaye sebenzisa iigaskets okanye i-sealant efanelekileyo ukuqinisekisa ukusebenza kokutywina kwevalvu yebhola.

5. Isixhobo sokuqhuba: Iivalvu zebhola ezineebhokisi zegiya okanye iidrive zomoya kufuneka zifakwe zimi nkqo, kwaye ziqinisekise ukuba isixhobo sokuqhuba singaphezulu kombhobho ukuze kube lula ukusebenza nokugcinwa.

Ngamafutshane, ukufakwa kweevalvu zebhola yinkqubo ecokisekileyo nebalulekileyo ekufuneka yenziwe ngokuhambelana nemiyalelo yokufakela kunye neenkqubo zokusebenza. Ukufakelwa ngokufanelekileyo kunokuqinisekisa ukusetyenziswa okuqhelekileyo kwevalvu yebhola, kuphucule ubomi benkonzo yevalvu yebhola, kwaye kunciphise umngcipheko wokuvuza kunye nezinye iingxaki.
