Yintoni iValve yeBhalbhu yePort epheleleyo: Umahluko oPhambili kunye neeNzuzo

Iivalvu zebholaziphakathi kweevalvu ezisetyenziswa kakhulu kwiinkqubo zolawulo lolwelo kwimizi-mveliso nakwezorhwebo. Uyilo lwazo olulula, ukuqina, kunye nokutywinwa okuthembekileyo kuzenza zilungele ukusetyenziswa okufuna ukuvalwa ngokukhawuleza okanye ukulawulwa kokuhamba kwamanzi. Phakathi kweentlobo ngeentlobo zeevalvu zebhola,iivalvu zebhola zezibuko ezipheleleyoZibalasele ngoyilo lwazo olukhethekileyo kunye neenzuzo zokusebenza. Kweli nqaku, siza kuhlola ukuba yintoni ivalvu yebhola ye-port epheleleyo, indlela eyahluke ngayo kwiivalvu ze-port ezincitshisiweyo, iimpawu zayo eziphambili zokusebenza, kunye nezona zicelo zayo ziqhelekileyo.

Yintoni iValve yeBhola

Ivalvu yebholayivalvu ejika ngekota esebenzisa ibhola engenanto, ejikelezayo enembobo (umngxuma) embindini wayo ukulawula ukuhamba kolwelo. Xa ivalvu ivuliwe, imbobo ihambelana nombhobho, ivumela ulwelo ukuba ludlule. Ukujikelezisa ibhola ngee-degrees ezingama-90 usebenzisa isiphatho okanye i-actuator kuvala ivalvu, kuthintela ukuhamba kolwelo. Iivalvu zebhola zaziwa ngezi zinto zilandelayo:

• Ukusebenza ngokukhawuleza(vula/vala ngemizuzwana).
• Ukutywinwa kweendlela ezimbini(ukuhamba kungahamba nakweyiphi na indlela).
• Ukwehla koxinzelelo oluphantsixa ivuliwe ngokupheleleyo.
• Ukuqinakwiindawo ezinoxinzelelo oluphezulu okanye ezishushu kakhulu.

Iivalvu zebhola zahlulwe ngokobukhulu bezibuko, uyilo, kunye nezinto ezisetyenziswayo.ubungakanani bezibuko—ebhekisa kububanzi bebhore—idlala indima ebalulekileyo ekumiseleni umthamo wokuhamba kwevalvu kunye nokuhla koxinzelelo.

Yintoni iValve yeBhala yePort epheleleyo

Aivalvu yebhola yezibuko elipheleleyo(ekwabizwa ngokuba yiivalvu yebhola epheleleyo) yenzelwe ukuba ibe nobubanzi obufanayo nobubanziububanzi bangaphakathi (ID) bombhobho odibanisayoUmzekelo, ukuba ivalvu ifakwe kwipayipi eyi-intshi ezi-4, imbobo yevalvu yebhola egcweleyo nayo iya kuba yi-intshi ezi-4. Olu yilo lususa imida yokuhamba kwamanzi, luqinisekisa ukwehla okuncinci koxinzelelo kunye nokusebenza kakuhle kokuhamba kwamanzi.

Iimpawu eziphambili zeeValve zeBall zePort ezipheleleyo:

1. Ubungakanani beBore:Ihambelana nobubanzi bangaphakathi bombhobho.
2. Uyilo lomzimba:Umzimba wevalvu omkhulu xa uthelekiswa neevalvu zezibuko ezincitshisiweyo ukuze zilungele ibhola elikhulu.
3. Ukusebenza kakuhle kokuhamba kwamanzi:Phantse akukho xinzelelo lulahlekileyo xa luvuliwe ngokupheleleyo.
4. Izicelo:Ilungele iinkqubo ezifuna ukuhamba kwamanzi okanye ukufunxwa kweengulube ngaphandle kwemiqathango (ukucoca/ukulungisa).

Ivalvu yeBhala yePort epheleleyo xa ithelekiswa neValve yeBhala yePort encitshisiweyo

Umahluko ophambili phakathi kweevalvu ze-full port kunye ne-reduced port ball valves ulele kwi-ubungakanani bebhore:

Ukukhetha iiValve zeBhalbhu eziPheleleyo:

• Iinkqubo ezifunaukuhamba okungenamkhawulo(umz., ukhuseleko lomlilo, unikezelo lwamanzi).
• Iipayipi ezifunekayoihagu(izixhobo zokucoca zidlule emgceni).
• Ukuphathaulwelo oluqinileyo, amaqhekeza, okanye imidiya erhabaxa.

Ixesha lokukhetha iiValve zePort ezincitshisiweyo:

• Iiprojekthi ezijonga uhlahlo-lwabiwo mali kunyeiimfuno zokuhamba kwamanzi okuphakathi.
• Iinkqubo apho indawo okanye ubunzima bungumqobo.

Iimpawu zomsebenzi zeeValve zeBhalbhu zePort ezipheleleyo

1.Uthintelo lokuhamba kwamanzi olungekhoyo

Imbobo enkulu iqinisekisa ukuba ulwelo luhamba ngqo kwivalvu ngaphandle kokuphazanyiswa okanye ukulahleka koxinzelelo. Oku kubaluleke kakhulu kwiinkqubo ezihamba amanzi amaninzi ezifana nokusasazwa kwamanzi okanye imibhobho yeoyile.

2.Ukuhambelana kweePigging

Iivalvu zezibuko ezipheleleyo ziyavumelaiihagu(izixhobo zokucoca okanye zokuhlola) ukuze zidlule kumbhobho ngaphandle kokuphazanyiswa, nto leyo ezenza zibe yimfuneko kumashishini eoyile negesi, amachiza kunye namanzi amdaka.

3.Ukutywina kweZindlela ezimbini

Iivalvu zebhola ezivalekayo ngokupheleleyo zitywina ngokulinganayo kuzo zombini iindlela zokuhamba, nto leyo enika ukuguquguquka kwindlela yoyilo lwenkqubo.

4.Ukuhlala ixesha elide kwiHarsh Media

Imbobo egudileyo kunye nolwakhiwo oluqinileyo (oludla ngokwenziwa ngentsimbi engagqwaliyo okanye ii-alloys) lumelana nokukhukuliseka okuvela kulwelo olurhabaxa okanye olubolayo.

5.Ukugcinwa okulula

Iivalvu ezininzi zezibuko ezigcweleyo zineuyilo lwemizimba eyahlukeneyo, okuvumela ukufikelela lula kwizinto zangaphakathi zokucoca okanye zokulungisa.

Yintoni iValve yeBhala yePort epheleleyo esetyenziselwa yona

Iivalvu zebhola ezipheleleyo zezibuko zisetyenziswa kumashishini apho ukusebenza kakuhle kokuhamba kwamanzi, ukugaya, okanye ukuhambelana kwemidiya zizinto eziphambili:

1.Imibhobho yeoyile negesi

• Ukuthutha ioyile ekrwada, igesi yendalo, okanye iimveliso ezicociweyo.
• Ukuvumela ukufuywa kweehagu ukuze kuhlolwe kwaye kugcinwe imibhobho.

2.Iinkqubo zamanzi kunye namanzi amdaka

• Iinethiwekhi zobonelelo lwamanzi zikamasipala.
• Ukuphathwa kodaka kwiindawo zokucocwa kwamanzi amdaka.

3.Ukucubungula iikhemikhali

• Ukudlulisa iikhemikhali ezirhabaxa okanye ezirhabaxa (umz., iipolymers, ii-asidi).

4.Iinkqubo zoKhuselo loMlilo

• Ukuqinisekisa ukuhamba kwamanzi okuphezulu ngexesha leengxakeko.

5.Ukuveliswa koMbane

• Iinkqubo zamanzi okupholisa kwizityalo zenyukliya okanye ezishushu.

6.Ulwandle kunye nokwakha iinqanawa

• Ukuhanjiswa kwepetroli kunye nolawulo lwamanzi ahambayo.

Isiphelo

A ivalvu yebhola yezibuko elipheleleyoyivalvu esebenza kakhulu eyenzelwe iinkqubo ezifuna amandlaukuhamba okungenamkhawulo, amandla okukhwela ihagu, kunye nokulahleka okuncinci koxinzeleloNangona inkulu kwaye ibiza kakhulu kunevalvu yezibuko encitshisiweyo, iingenelo zayo kwizicelo ezibalulekileyo—ezifana nemibhobho yeoyile, ukhuseleko lomlilo, kunye nokuphathwa kodaka—zenza ukuba ibaluleke kakhulu. Ngokuqonda umahluko phakathi kweevalvu zezibuko ezipheleleyo kunye neevalvu zezibuko ezincitshisiweyo, iinjineli kunye nabaqhubi banokukhetha ivalvu efanelekileyo ukuze baphucule ukusebenza kakuhle, banciphise iindleko zokusebenza, kwaye bandise ubomi benkqubo.
