Iivalvu zeBhola: Isikhokelo esipheleleyo seeCandelo, iiNtlobo, kunye nezicelo

Iivalvu zebhola ziphakathi kweevalvu ezisetyenziswa kakhulu kwiinkqubo zoshishino nezokuhlala ngenxa yokuthembeka kwazo, ukuqina kwazo, kunye nokusebenza kwazo ngokulula. Eli nqaku lihlola ukuba yintoni ivalvu yebhola, izinto zayo ezibalulekileyo (umzimba, ibhola, isihlalo), ukuhlelwa, imigangatho yoxinzelelo kunye nobukhulu, kunye neendlela zokusebenzisa. Nokuba ungunjineli, ingcali yokuthenga, okanye umthandi we-DIY, esi sikhokelo siya kukunceda uqonde indlela yokukhetha ivalvu yebhola efanelekileyo kwiimfuno zakho.

Yintoni iValve yeBhola

A ivalvu yebholayivalvu ejika ngekota esebenzisa ibhola engenanto, eneembobo, nejikelezayo ukulawula ukuhamba kolwelo. Xa imbobo yebhola ihambelana nombhobho, ulwelo luhamba ngokukhululekileyo; ukujikeleza ibhola ngama-90 degrees kuthintela ukuhamba kwayo ngokupheleleyo. Uyilo lwayo olulula luqinisekisa ukusebenza ngokukhawuleza, ukuvuza okuncinci, kunye nokuhambelana namanzi, ioyile, igesi, kunye nemidiya ebolileyo.

Izinto ezibalulekileyo zeValve yeBhola

1. Umzimba weValve yeBhola

Iumzimba wevalvu yebholayiqokobhe langaphandle eligcina izinto zangaphakathi. Ngokwesiqhelo lenziwe ngezinto ezomeleleyo ezifana nentsimbi engagqwaliyo, ubhedu, okanye iPVC, kuxhomekeke kwisicelo. Uyilo lomzimba lumisela umlinganiselo woxinzelelo lwevalvu kunye nohlobo loqhagamshelo (olunemisonto, olujijekileyo, okanye oluyi-wafer).

2. Ibhola yeValve yeBhola

Iibhola yevalvu yebholayi-sphere ejikelezayo ene-bore (umngxuma) embindini wayo. Idla ngokugqunywa nge-chrome okanye igqunywe ngezinto ezifana ne-PTFE ukunciphisa ukungqubana nokumelana nokugqwala. Ukulungiswa ngokuchanekileyo kwebhola kuqinisekisa ukutywinwa okuqinileyo nokusebenza kakuhle.

3. Isihlalo seValve yeBhola

Iisihlalo sevalvu yebholayinxalenye efana nesangqa eyenza uphawu phakathi kwebhola nomzimba. Izihlalo zihlala zenziwe ngezinto ezithambileyo ezifana ne-PTFE okanye ii-thermoplastics eziqinisiweyo ukuqinisekisa ukusebenza okungenakuvuza, nokuba kuphantsi koxinzelelo oluphezulu.

Iintlobo zeeValve zeBhola ezisekelwe kwiSitayile soQhagamshelo

1. Ivalvu yeBhola eNxibelelweyo

A ivalvu yebhola eneentamboinemisonto yesilisa okanye yesifazane eziphelweni zayo, ivumela ukufakwa ngqo kwimibhobho. Ilungele iinkqubo zokuhlala ezinoxinzelelo oluphantsi (umz., imibhobho yamanzi, i-HVAC), ezi valves zingabizi kakhulu kwaye kulula ukuzifaka ngaphandle kokuwelda.

Izicelo:

- Ubonelelo lwamanzi kwiindawo zokuhlala

- Imigca yegesi

- Iinkqubo zoshishino ezincinci

2. Ivalvu yeBhola eFlanged

A ivalvu yebhola ejikeleziweyoineziphelo ezijijekileyo ezibotshelelwe kwiiflange zepayipi. Ezi valve ziphatha iinkqubo zoxinzelelo oluphezulu kunye nobukhulu obukhulu, zibonelela ngokugcinwa okulula kunye nokuqhaqhwa. Iigaskets phakathi kweeflange ziqinisekisa uqhagamshelo olukhuselekileyo nolungavuziyo.

Izicelo:

- Imibhobho yeoyile negesi

- Izityalo zokucubungula iikhemikhali

- Iindawo zokucoca amanzi

3. Ivalvu yeBhola yeWafer

A ivalvu yebhola yewafer(okanye *ivalvu yebhola yesitayile se-clamp*) ibekwe phakathi kweeflange ezimbini zepayipi kusetyenziswa iibholiti. Zincinci kwaye zilula, ezi valve zilungele iinkqubo ezixinzelelweyo kodwa azinazo ii-end connections, zixhomekeke kuxinzelelo lweflange ukuze zitywinwe.

Izicelo:

- Ukulungiswa kokutya neziselo

- Iinkqubo ze-HVAC ezincinci

- Iinkqubo ze-hydraulic ezinoxinzelelo oluphantsi

Ulwahlulo lweeValve zeBhola ngokweYilo

1. Ivalvu yeBhola edadayo

Ibhola ibanjwe zizihlalo ezibini kwaye idada kancinci phantsi koxinzelelo. Ifanelekile kwiivalvu ezincinci ukuya kweziphakathi, olu yilo lubiza kancinci kodwa lunokuba nzima xa kunyuke uxinzelelo oluphezulu.

2. Ivalvu yeBhola yeTrunnion

Ibhola iqiniswe yindlela ye-trunnion (pivot), enciphisa i-torque yokusebenza kwaye iphatha uxinzelelo oluphezulu. Ixhaphakile kwimibhobho yeoyile negesi.

3. Izibuko Elipheleleyo vs. Izibuko Elincitshisiweyo

- I-Valve yeBhola yePort epheleleyo: Imbobo ihambelana nobubanzi bombhobho, nto leyo enciphisa ukumelana nokuhamba kwamanzi.

- Ivalvu yeBhalbhu yePort encitshisiweyo: Imbobo incinci, inciphisa ubungakanani bevalvu kunye neendleko kodwa inyusa ukwehla koxinzelelo.

Uvavanyo kunye nobukhulu be-Ball Valve Pressure

Uvavanyo loxinzelelo

Iivalvu zebhola zilinganiswa ngokusekelwe kuxinzelelo lwazo oluphezulu oluvumelekileyo (umz., i-ANSI Class 150, 300, 600). Iiklasi eziphezulu zibonisa ukumelana noxinzelelo olukhulu. Umzekelo:

- Iklasi ye-150: 285 PSI kwi-100°F
- Iklasi 600: 1,440 PSI kwi-100°F

Izinto Ezichaphazela Amandla Oxinzelelo:

- Amandla ezinto eziphathekayo

- Ukuthembeka kwesihlalo kunye nesitywino

- Uhlobo loqhagamshelo (iivalvu ezineeflange zisingatha uxinzelelo oluphezulu)

Imigangatho yobukhulu

Ubungakanani beevalvu zebhola buqala kwi-¼ intshi (yokusetyenziswa emakhaya) ukuya ngaphezulu kwe-48 intshi (iipayipi zemizi-mveliso). Imigangatho eqhelekileyo ibandakanya:

- I-NPT (Umsonto weSizwe wePipe): Kwiivalvu ezinemisonto.

- I-ASME B16.10: Ngokwemilinganiselo yokujonga ubuso ngobuso.

- I-ASME B16.5: Kwiivalvu ezijijekileyo.

Iindlela Zokusebenza Kwevalvu Yebhola

1. Ukusebenza ngesandla

Isebenza nge-lever okanye i-handwheel. Ilungele iivalvu ezincinci okanye iinkqubo ezifuna ukulungiswa rhoqo.

2. Ukusebenza kwe-Pneumatic

Isebenzisa umoya ocinezelweyo ukuze isebenze ngokuzenzekelayo ivalvu. Ilungele iindawo ezikude okanye ezinobungozi.

3. Ukusebenza kombane

Isebenza ngeemoto zombane, nto leyo evumela ukuhlanganiswa neenkqubo zolawulo ukuze kulawulwe ukuhamba kombane ngokuchanekileyo.

Indlela yokukhetha iValve yeBhola echanekileyo

1. Ukuhambelana kweMidiya: Qinisekisa ukuba izixhobo (umzimba, ibhola, isihlalo) ziyamelana nokugqwala okuvela kulwelo.

2. Uxinzelelo kunye nobushushu: Tshatisa umlinganiselo wevalvu neemfuno zenkqubo.

3. Uhlobo loQhagamshelo: Khetha intambo, iflange, okanye i-wafer ngokusekelwe kuyilo lombhobho.

4. Ubungakanani bePort: Khetha iivalvu zezibuko ezipheleleyo kwiinkqubo ezihamba ngamandla.

5. Ukusebenza: Yenza kube ngokuzenzekelayo ukuba kufuneka uhlengahlengiso rhoqo okanye ulawulo olukude.
