Iivalvu zeBhola: Isikhokelo esiBanzi kuMalunga, Iintlobo, kunye nezicelo

Iivalvu zebhola ziphakathi kwezona zisetyenziswa kakhulu kwiinkqubo zoshishino kunye neendawo zokuhlala ngenxa yokuthembeka kwazo, ukuqina, kunye nokusebenza ngokulula. Eli nqaku liphonononga ukuba yintoni ivalve yebhola, amacandelo ayo abalulekileyo (umzimba, ibhola, isihlalo), ulwahlulo, uxinzelelo kunye nemigangatho yobungakanani, kunye neendlela zokusebenzisa. Nokuba uyinjineli, ingcali yokuthengwa kwempahla, okanye umthandi we-DIY, esi sikhokelo siya kukunceda uqonde indlela yokukhetha ivalve yebhola efanelekileyo kwiimfuno zakho.

Yintoni iValve yeBhola

A ivalve yebholayivalve yekota-turn esebenzisa ibhola enomngxuma, enemingxuma, kunye nepivoting ukulawula ukuhamba kolwelo. Xa umbhobho webhola uhambelana nombhobho, ulwelo luhamba ngokukhululekileyo; ukujikeleza ibhola ngee-degrees ezingama-90 kuthintela ukuhamba ngokupheleleyo. Uyilo lwayo olulula luqinisekisa ukusebenza okukhawulezayo, ukuvuza okuncinci, kunye nokuhambelana namanzi, ioyile, igesi, kunye nemithombo yeendaba eyonakalisayo.

Amacandelo angundoqo weValuvu yeBhola

1. Umzimba weValve yeBhola

Iumzimba ivelufa yebholaliqokobhe elingaphandle eligcina amalungu angaphakathi. Ngokwesiqhelo yenziwe ngezinto ezomeleleyo njengentsimbi engatyiwa, ubhedu, okanye iPVC, kuxhomekeke kwisicelo. Uyilo lomzimba lumisela umlinganiselo woxinzelelo lwevalve kunye nodidi loqhagamshelo (umsonto, onomsonto, okanye osicaba).

2. Ibhola yeValve yeBhola

IIbhola yevalve yebholayingqukuva ejikelezayo enomngxuma (umngxuma) embindini wayo. Ihlala i-chrome-plated okanye igqunywe ngezinto ezifana ne-PTFE ukunciphisa ukukhuhla kunye nokuxhathisa ukubola. Ukuchaneka kwebhola kuqinisekisa ukutywinwa okuqinileyo kunye nokusebenza kakuhle.

3. Isihlalo seValve yeBhola

Iisihlalo sevalve yebholayinxalenye emile njengesangqa eyenza itywina phakathi kwebhola nomzimba. Izihlalo zihlala zenziwe ngezinto ezithambileyo ezifana ne-PTFE okanye i-thermoplastics eyongeziweyo ukuqinisekisa ukusebenza okuvuzayo, naphantsi koxinzelelo oluphezulu.

Iindidi zeVavu zeBhola eziSekwe kwiSimbo soQhagamshelwano

1. IValve yeBhola enemisonto

A ivalve yebhola ephothiweyoifaka imisonto eyindoda okanye eyamaziyo ekupheleni kwayo, ivumela ukufakelwa isikrufu ngqo kwimibhobho. Ilungele iinkqubo zokuhlala eziphantsi koxinzelelo (umzekelo, imibhobho yamanzi, i-HVAC), ezi zivalo zingabizi kwaye kulula ukuzifaka ngaphandle kwe-welding.

Usetyenziso:

- Unikezelo lwamanzi kwindawo yokuhlala

- Imigca yegesi

- Iinkqubo zamashishini amancinci

2. Ivalve yeBhola eneFlanged

A ivalve yebhola eneflangeiziphelo ezinecala ezibotshelelwe kwiiflange zemibhobho. Ezi zivalo zibamba i-high-pressure kunye ne-diameter-diameter systems, enikezela ukugcinwa lula kunye nokuqhaqha. Iigaskets phakathi kweeflange ziqinisekisa uqhagamshelwano olukhuselekileyo, olungavuziyo.

Usetyenziso:

- Imibhobho yeoli negesi

- Amaziko okulungisa imichiza

- Amaziko okucoca amanzi

3. IValve yeBhola yeWafer

A ivalve yebhola emhlophe(okanye *ivalve yebhola yohlobo lokubamba*) ifakwe phakathi kweeflenge ezimbini zemibhobho kusetyenziswa iibholithi. I-Compact kwaye ikhaphukhaphu, ezi zivalo zihambelana neenkqubo ezicinezela indawo kodwa azinanxibelelwano, zixhomekeke kuxinzelelo lwe-flange lokutywinwa.

Usetyenziso:

- Ukulungiswa kokutya nesiselo

- Iinkqubo ze-HVAC eziQinisekileyo

- Iinkqubo zoxinzelelo oluphantsi lwe-hydraulic

Ukuhlelwa kweValve yeBhola ngoYilo

1. IValve yeBhola edadayo

Ibhola ibanjwe zizihlalo ezibini kwaye idada kancinci phantsi koxinzelelo. Ifanelekile kwiivalvu ezincinci ukuya eziphakathi, olu yilo luyindleko kodwa lunokuba nzima kunye noxinzelelo oluphezulu.

2. IValve yeBhola yeTrunnion

Ibhola igxininiswe yi-trunnion (pivot) indlela, ukunciphisa i-torque yokusebenza kunye nokuphatha uxinzelelo oluphezulu. Okuqhelekileyo kwimibhobho yeoli kunye negesi.

3. Isibuko esiPheleleyo vs. Isibuko esiNcitshisiweyo

- IValve yeBhola yePort epheleleyo: Ibhore ihambelana nobubanzi bombhobho, ukunciphisa ukuxhathisa ukuhamba.

- IValve yeBhola yePort eNcitshisiweyo: I-bore incinci, inciphisa ubungakanani bevalve kunye neendleko kodwa ukunyuka koxinzelelo.

I-Ball Valve Pressure Ratings kunye nobukhulu

Amanqaku oxinzelelo

Iivalvu zebhola zilinganiswe ngokusekelwe kuxinzelelo lwazo oluvumelekileyo (umzekelo, i-ANSI Class 150, 300, 600). Iiklasi eziphezulu zibonisa ukuchasana koxinzelelo olukhulu. Umzekelo:

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

Imiba echaphazela amandla oxinzelelo:

- Amandla ezinto eziphathekayo

- Isihlalo kunye nokutywinwa kwengqibelelo

-Udidi loqhagamshelo (iivalvu eziphothiweyo zibamba uxinzelelo oluphezulu)

Imigangatho yobungakanani

Iisayizi zevalvu yebhola ziqala ukusuka kwi-¼ intshi (yokusetyenziswa kwindawo yokuhlala) ukuya ngaphezulu kwe-intshi ezingama-48 (imibhobho yoshishino). Imigangatho eqhelekileyo iquka:

- I-NPT (Umsonto wombhobho weSizwe): Yeevalvu ezithungelweyo.

- ASME B16.10: Ngemilinganiselo yobuso ngobuso.

- I-ASME B16.5: Yeevalvu eziphothiweyo.

Iindlela zokuSebenza kweValve yeBhola

1. Ukwenziwa kweNcwadana

Isebenza nge-lever okanye ngesandla. Eyona nto ingcono kwiivalvu ezincinci okanye iinkqubo ezifuna ukulungiswa okungaqhelekanga.

2. I-Pneumatic Actuation

Isebenzisa umoya ocinezelweyo ukwenza ivalvu isebenze. Ilungele indawo ezikude okanye ezinobungozi.

3. Ukusebenza koMbane

Ixhaswe ziinjini zombane, ezivumela ukudityaniswa kunye neenkqubo zolawulo lolawulo lokuhamba ngokuchanekileyo.

Indlela yokukhetha iValve yeBhola eLungileyo

1. Ukuhambelana kweMedia: Qinisekisa izixhobo (umzimba, ibhola, isihlalo) zixhathise ukubola kulwelo.

2. Uxinzelelo kunye nobushushu: Tshatisa umlinganiselo wevalve kwiimfuno zenkqubo.

3. Uhlobo loQhagamshelwano: Khetha umsonto, iflenji, okanye iwafer esekwe kuyilo lombhobho.

4. Ubungakanani bePort: Khetha iivalvu zezibuko ezipheleleyo kwiinkqubo eziphezulu zokuhamba.

5. Intshukumo: Zizenzele ukuba uhlengahlengiso rhoqo okanye ulawulo olukude luyafuneka.

Ukuqukumbela

Iivalvu zebhola ziyaguquguquka, ziqinile, kwaye ziyimfuneko ekulawuleni ukuhamba kwamanzi kumashishini. Ukuqonda iinxalenye zabo—umzimba ivelufa yebhola, ibhola, kwayeisihlalo-kunye neentlobo ezifanaumsonto, flanged, kwayeiqhekezana lesonkaiivalve zebhola, iqinisekisa ukusebenza kakuhle kwenkqubo. Ngokuqwalasela iireyithingi zoxinzelelo, ubungakanani, kunye neendlela zokuvula, unokukhetha isivalo esihlangabezana neemfuno zakho zokusebenza. Hlala usebenzisana nomenzi othembekileyo ukuqinisekisa umgangatho kunye nokuthotyelwa kwemigangatho yoshishino.
