Indlela yokufaka i-ball valve?

Indlela yokufaka ivalvu yebhola idinga ukunqunywa ngokuya ngohlobo lwevalvu yebhola, izici zombhobho kanye nendawo ethile yokusetshenziswa. Nazi izinyathelo zokufaka ezijwayelekile kanye nezinyathelo zokuphepha:

Okokuqala, lungiselela ngaphambi kokufakwa

1. Qinisekisa isimo sephayiphi: qiniseka ukuthi iphayiphi ngaphambi nangemva kwe-valve yebhola isilungile, futhi iphayiphi kufanele ibe yi-coaxial, futhi indawo yokuvala yama-flange amabili kufanele ifane. Iphayiphi kufanele ikwazi ukumelana nesisindo se-valve yebhola, ngaphandle kwalokho kudingeka kulungiselelwe ukwesekwa okufanele ephayiphini.

2. Ukuhlanza amapayipi namavalvu ebhola: hlanza amavalvu ebhola namapayipi, susa uwoyela, i-welding slag kanye nakho konke ukungcola okusepayipini, bese uhlanza ingaphakathi nengaphandle kwevalvu yebhola ukuqinisekisa ukuthi akukho ukungcola namafutha.

3. Hlola ivalvu yebhola: hlola uphawu lwevalvu yebhola ukuqinisekisa ukuthi ivalvu yebhola iphelele. Vula futhi uvale ivalvu yebhola ngokugcwele izikhathi eziningana ukuqinisekisa ukuthi isebenza kahle.

Okwesibili, izinyathelo zokufaka

1. I-flange yokuxhuma:

- Susa isivikelo kuma-flange axhumanisayo kuzo zombili izinhlangothi zevalvu yebhola.

- Qondanisa i-flange ye-ball valve ne-flange yepayipi, uqinisekise ukuthi imigodi ye-flange iqondile.

- Sebenzisa amabhawodi e-flange ukuxhuma i-valve yebhola kanye nepayipi ngokuqinile, bese uqinisa amabhawodi ngalinye ngalinye ukuqinisekisa ukuxhumana okuqinile.

2. Faka i-gasket:

- Faka inani elifanele le-sealant noma ufake ama-gasket okuvala endaweni yokuvala phakathi kwe-ball valve kanye nepayipi ukuqinisekisa ukuthi indawo yokuvala ithambile futhi isebenza kahle.

3. Xhuma idivayisi esebenzayo:

- Xhuma ikhanda lesiqu se-valve se-ball valve kudivayisi yokusebenza (njengesibambo, i-gearbox noma i-pneumatic drive) ukuqinisekisa ukuthi idivayisi yokusebenza ingakwazi ukuzungeza kahle isiqu se-valve.

4. Hlola ukufakwa:

- Ngemva kokuthi ukufakwa sekuqediwe, hlola ukuthi ukufakwa kwevalvu yebhola kuyahlangabezana yini nezidingo, ikakhulukazi hlola ukuthi uxhumano lweflange luqinile yini nokuthi ukusebenza kokuvala kuhle yini.

- Zama ukusebenzisa ivalvu yebhola izikhathi eziningana ukuqinisekisa ukuthi ivalvu ingavuleka futhi ivaleke kahle.

Okwesithathu, izinyathelo zokuqapha ukufakwa

1. Indawo yokufaka: I-valve yebhola ngokuvamile kufanele ifakwe epayipini elivundlile, uma kufanele ifakwe epayipini elivundlile, isiqu se-valve kufanele sibheke phezulu, ukuze kugwenywe ukuthi umongo we-valve ucindezelwe uketshezi olusesihlalweni, okuholela ekutheni i-valve yebhola ingavalwa ngokujwayelekile.

2. Isikhala sokusebenza: Shiya isikhala esanele ngaphambi nangemva kwevalvu yebhola ukuze kube lula ukusebenza nokugcinwa kwevalvu yebhola.

3. Gwema umonakalo: Ngesikhathi senqubo yokufaka, qaphela ukugwema ukuthi ivalvu yebhola ingathinteki noma iklwejwe, ukuze ingalimazi ivalvu noma ithinte ukusebenza kwayo kokuvala.

4. Ukusebenza kokuvala: Qinisekisa ukuthi indawo yokuvala ibushelelezi futhi ihlanzekile, bese usebenzisa ama-gasket noma i-sealant efanele ukuqinisekisa ukusebenza kokuvala kwevalvu yebhola.

5. Idivayisi yokushayela: Ama-valve ebhola anama-gearbox noma ama-pneumatic drive kufanele afakwe eqonde phezulu, futhi aqinisekise ukuthi idivayisi yokushayela ingaphezulu kwepayipi ukuze kube lula ukuyisebenzisa nokulungisa.

Ngamafuphi, ukufakwa kwamavalvu ebhola kuyinqubo ecophelelayo nebalulekile edinga ukwenziwa ngokuhambisana nemiyalelo yokufaka kanye nezinqubo zokusebenza. Ukufakwa okufanele kungaqinisekisa ukusetshenziswa okuvamile kwevalvu yebhola, kuthuthukise impilo yesevisi yevalvu yebhola, futhi kunciphise ingozi yokuvuza nokunye ukwehluleka.
