Isikhokelo seMveliso yeValve yeBhola ye-intshi ezi-2: Ubungakanani, Uvavanyo loxinzelelo, Izixhobo kunye nezicelo

Ivalvu yeBhola ye-Inch ezi-2: Isishwankathelo seMveliso

Ivalvu yebhola eyi-intshi ezi-2 yivalvu ejika ikota eyenzelwe ukulawula ngokuchanekileyo ukuhamba kolwelo kwiipayipi. Uyilo lwayo oluncinci, ukuqina, kunye nokuguquguquka kwenza ukuba ibe lukhetho oludumileyo kumashishini afana neoyile negesi, ukucubungula iikhemikhali, unyango lwamanzi, kunye ne-HVAC.

Iinkcukacha eziphambili

1. Ubungakanani:

– Ububanzi obuqhelekileyo: 2 intshi (DN50)

– Ubukhulu boBuso noBuso: Ihambelana nemigangatho ye-ASME B16.10.

2. Uvavanyo loxinzelelo:

– Amanqaku aqhelekileyo:Iklasi ye-150(285 PSI),Iklasi yama-300(740 PSI),Iklasi 600(1,480 PSI).

– Ingenziwa ngokwezifiso kwiingcinezelo eziphezulu (xa iceliwe).

3. Iintlobo zoQhagamshelo:

–I-Flanged: Imigangatho ye-ASME B16.5 okanye ye-EN 1092-1.

–Ifakwe imisonto: I-NPT (iNational Pipe Thread) okanye i-BSP (iBritish Standard Pipe).

–I-Socket WeldokanyeUkuwelda Kwempundu: Kwiinkqubo ezinoxinzelelo oluphezulu.

4. Izixhobo:

–Umzimba: Intsimbi yeCarbon,Yenziwe ngentsimbi eshayinayo(SS304/SS316),Intsimbi Engagqwaliyo Ephindwe Kabini, SDSS,Intsimbi yobhedu, okanye i-Ductile Iron.

–Ibhola: Intsimbi engagqwaliyo egqunywe nge-chrome okanye igqunywe nge-ceramic ukuze ikwazi ukumelana nokurhawuzelelwa.

–Izihlalo: I-PTFE (Teflon), i-PFA, i-PPL, okanye isinyithi-ukusuka-kwisinyithi kwizicelo zobushushu obuphezulu.

5. Ubushushu bokusebenza:

– Izitywino eziQhelekileyo: -20°C ukuya kuma-200°C (-4°F ukuya kuma-392°F).

– Izitywino zobushushu obuphezulu: Ukuya kuthi ga kwi-450°C (842°F) ezinezihlalo zesinyithi.

6. Iindlela Zokusebenza:

–Ngesandla: Isitshixo, Ibhokisi yegiya okanye yelever iyasebenza.

–Okuzenzakalelayo: I-Pneumatic, yombaneokanyeii-actuators ze-hydraulicyokulawula kude.

Ulwahlulo

1. Ngoyilo:

–Izibuko elipheleleyo: Uyilo olupheleleyo lunciphisa ukwehla koxinzelelo.

–Izibuko Elincitshisiweyo: Incinci, ingabizi kakhulu xa isetyenziswa ngokubanzi.

2. Ngomsebenzi:

–Ibhola Elidadayo: Ifanelekile kuxinzelelo oluphantsi ukuya koluphakathi.

–I-Trunnion efakwe: Ilungele iinkqubo ezinoxinzelelo oluphezulu kunye nobukhulu obukhulu.

Iingenelo

- Ukusebenza ngokukhawuleza: Ukujikeleza kweedigri ezingama-90 ukuze kucinywe ngokukhawuleza.

- Ukugcinwa Okuphantsi: Isakhiwo esilula esinezinto ezincinci zokuguguleka.

- Ukutywina Okuqinileyo Okuvuzayo: Izihlalo ze-PTFE ziqinisekisa ukuba akukho kuvuza.

- Ukumelana nokugqwala: Intsimbi engatyiwayo okanye izinto ezigqunyiweyo zeendawo ezinobungozi.

- Ukuguquguquka: Iyahambelana nezinto ezimanzi, iigesi, kunye ne-slurry.

Iingcebiso Zokulungisa

1. Ukuthambisa rhoqo: Faka igrisi kwisiqu uze uyivale rhoqo ngonyaka.

2. Hlola iiMpawu: Buyisela izihlalo ze-PTFE ezigugileyo ukuze ugcine ukusebenza kokutywina.

3. Izinto zangaphakathi ezicocekileyo: Hlamba ivalvu ukuze ususe inkunkuma xa kusetyenzwa udaka.

4. Jonga ii-Actuators: Qinisekisa ukuba izixhobo zomoya/zombane zisebenza kakuhle.

Izicelo

- Ioyile kunye neGesi: Ukwahlulwa kunye nokulawulwa kwemibhobho.

- Izityalo zeKhemikhali: Ukuphatha ulwelo oludlakadlaka.

- Unyango lwamanzi: Ulawulo lokuhamba kwamanzi kwiimpompo nakwiitanki.

- Iinkqubo ze-HVAC: Ulawulo lwemidiya yokufudumeza/yokupholisa.

Ivalvu yebhola ye-intshi ezi-2idibanisa ulwakhiwo oluqinileyo kunye nokuguquguquka, ukuqinisekisa ukusebenza okuthembekileyo kwiindawo zoshishino ezifuna amandla. Ukuze ufumane ulungelelwaniso olwenziwe ngokwezifiso, thetha nabavelisi ukuze uhlangabezane neemfuno ezithile zokusebenza.
