Yintoni iValve yeBhola yePort egcweleyo: Umahluko oPhambili kunye neZibonelelo

Iivalvu zebholaziphakathi kwezona zivalo zisetyenziswa kakhulu kwiinkqubo zolawulo lwemizi-mveliso kunye nezorhwebo. Uyilo lwazo olulula, ukuqina, kunye nokutywinwa okuthembekileyo kubenza balungele usetyenziso olufuna ukuvalwa okukhawulezileyo okanye ukulawulwa kokuhamba. Phakathi kweentlobo ezahlukeneyo zeevalve zebhola,iivalvu zebhola ezigcweleyobavelele kuyilo lwabo olulodwa kunye neenzuzo zokusebenza. Kweli nqaku, siza kuphonononga ukuba yintoni ivalve yebhola egcweleyo, ihluke njani kwiivalvu zezibuko ezincitshisiweyo, iimpawu zayo eziphambili zokusebenza, kunye nezona zicelo zixhaphakileyo.

Yintoni iValve yeBhola

Ivalve yebholayivalve yekota-turn esebenzisa umngxuma, ibhola ejikelezayo enebhore (umngxuma) kumbindi wayo ukulawula ukuhamba kolwelo. Xa ivalve ivuliwe, ibhore ihambelana nombhobho, ivumela ulwelo ukuba ludlule. Ukujikeleza ibhola i-90 degrees usebenzisa i-handle okanye i-actuator ivala i-valve, ivimbela ukuhamba. Iivalve zebhola zaziwa ngokwazo:

• Ukusebenza ngokukhawuleza(vula/vala ngemizuzwana).
• Ukutywinwa kabini(umqukuqelo unokuhamba uye kulo naliphi na icala).
• Uxinzelelo oluphantsi lwehlaxa ivulwe ngokupheleleyo.
• Ukuqinakwindawo ezinoxinzelelo oluphezulu okanye ubushushu obuphezulu.

Iivalvu zebhola zihlelwa ngokobungakanani bezibuko, uyilo, kunye nezinto eziphathekayo. Iubungakanani bezibuko-kubhekiselele kububanzi bombhobho-udlala indima ebalulekileyo ekumiseleni umthamo wokuhamba kwevalve kunye nokuhla koxinzelelo.

Yintoni iValve yeBhola yePort egcweleyo

AIvalve yebhola egcweleyo(ekwabizwa ngokuba yi-aivalve yebhola egcweleyo) iyilwe ngedayimitha yokubhonqa ehambelana neidiameter yangaphakathi (ID) yombhobho wokudibanisa. Umzekelo, ukuba ivelufa ifakwe kumbhobho we-intshi ezi-4, ukubhoboza kwevalve yebhola egcweleyo kuya kwenza i-intshi ezi-4. Olu luyilo lususa izithintelo zokuhamba, ukuqinisekisa ukuhla koxinzelelo oluncinci kunye nokusebenza kakuhle kokuhamba.

Iimpawu eziphambili zeeVave zeBhola yePort egcweleyo:

1. Ubungakanani Bore:Itshatisa idiamitha yangaphakathi yombhobho.
2. Uyilo loMzimba:Umzimba wevalvu omkhulu xa kuthelekiswa neevalvu zezibuko ezincitshisiweyo ukuze kuhlaliswe ubungakanani obupheleleyo bebhola.
3. Ukusebenza kakuhle kokuHamba:Phantse ilahleko yoxinzelelo lweqanda xa ivuleke ngokupheleleyo.
4. Usetyenziso:Ilungele iinkqubo ezifuna ukuhamba okungathintelwanga okanye ukuhagwa (ukucoca/ukugcinwa).

IValve yeBhola yePort ePheleleyo vs

Umahluko ophambili phakathi kwezibuko elipheleleyo kunye neevalvu zebhola ezincitshisiweyo zilele kuzoubungakanani bomhlaba:

Unokukhetha nini iivalvu zeBhola yePort egcweleyo:

• Iinkqubo ezifunekayoukuhamba okungathintelwanga(umzekelo, ukhuseleko lomlilo, unikezelo lwamanzi).
• Imibhobho efunekayoiihagu(izixhobo zokucoca zidlule kumgca).
• Ukuphathaulwelo lwe-viscous, i-slurries, okanye i-media abrasive.

Unokukhetha nini iiValve zeZibuko eziNcitshisiweyo:

• Iiprojekthi ezijonga uhlahlo lwabiwo-mali ngeiimfuno zokuhamba okuphakathi.
• Iinkqubo apho indawo okanye ubunzima busisithintelo.

Iimpawu eziSebenzayo zeeValuvu zeBhola yePort egcweleyo

1.Uthintelo loMqukuqelo onguZero

Ubungakanani obugcweleyo buqinisekisa ukuba ulwelo luhamba ngokuthe ngqo kwivalve ngaphandle kwesiphithiphithi okanye ilahleko yoxinzelelo. Oku kubalulekile kwiinkqubo zokuhamba okuphezulu njengokuhanjiswa kwamanzi okanye imibhobho yeoli.

2.Ukuhambelana kweHagu

Iivalvu zezibuko ezipheleleyo zivumelaiihagu(izixhobo zokucoca okanye zokuhlola) ukuba zidlule kumbhobho ngaphandle kwesithintelo, zizenze ziyimfuneko kwimizi-mveliso yeoli negesi, imichiza, kunye namanzi amdaka.

3.Ukutywinwa kweendlela ezimbini

Iivalvu zebhola zezibuko ezigcweleyo zitywina ngokulinganayo ngokufanelekileyo kuzo zombini iindlela zokuhamba, zibonelela ngokuguquguquka kuyilo lwenkqubo.

4.Ukuhlala ixesha elide kwiMedia eHashe

Ulwakhiwo olugudileyo kunye nolwakhiwo olomeleleyo (kaninzi kwintsimbi engatyiwa okanye ialloyi) luxhathisa ukhukuliseko olusuka kulwelo olurhabaxa okanye oludlekayo.

5.ULondolozo olulula

Iivalvu ezininzi zezibuko ezigcweleyo zibonisa auyilo lokwahlula-hlula umzimba, ukuvumela ukufikelela lula kumacandelo angaphakathi ukucoca okanye ukulungiswa.

Yintoni iValve yeBhola yePort egcweleyo esetyenziselwa

Iivalvu zebhola zezibuko ezigcweleyo zibekwe kumashishini apho ukuhamba kakuhle, ukukhwela iihagu, okanye ukuhambelana kwemidiya zizinto eziphambili:

1.Imibhobho yeoli negesi

• Ukuthutha ioli ekrwada, igesi yendalo, okanye iimveliso ezisulungekisiweyo.
• Ukuvumela ukuba iihagu zihlolwe kwaye zigcinwe.

2.IiNkqubo zaManzi kunye naManzi amdaka

• Uthungelwano lonikezelo lwamanzi lukamasipala.
• Ukuphathwa koludaka kwiindawo zokucocwa kwamanzi amdaka.

3.Ukwenziwa kweeKhemikhali

• Ukuhanjiswa kweekhemikhali ze-viscous okanye abrasive (umz., iipolima, iiasidi).

4.IiNkqubo zokuKhusela uMlilo

• Ukuqinisekisa ukuhamba kwamanzi amaninzi ngexesha likaxakeka.

5.IsiZukulwana saMandla

• Iinkqubo zokupholisa zamanzi kwizityalo zenyukliya okanye ezishushu.

6.Ulwakhiwo lwaselwandle kunye nolwakhiwo lweenqanawa

• Ukuhanjiswa kwamafutha kunye nolawulo lwamanzi e-ballast.

Ukuqukumbela

A Ivalve yebhola egcweleyoyivalve yokusebenza ephezulu eyenzelwe iinkqubo ezifunayoukuhamba okungathintelwanga, ukukwazi ukukhwela iihagu, kunye nelahleko encinci yoxinzelelo. Ngoxa inkulu yaye inexabiso eliphantsi kunevalve yezibuko ecuthiweyo, iingenelo zayo kwizinto ezibalulekileyo—njengemibhobho yeoli, ukhuseleko emlilweni, nokuphathwa ngodaka—ziyenza ibaluleke kakhulu. Ngokuqonda umahluko phakathi kwe-port epheleleyo kunye nokunciphisa i-valve yebhola ye-port, iinjineli kunye nabaqhubi banokukhetha i-valve efanelekileyo yokuphucula ukusebenza kakuhle, ukunciphisa iindleko zokusebenza, kunye nokwandisa ixesha lokuphila kwenkqubo.
