Isebenza njani iValve yeBhola eSebenzayo yePneumatic

Iivalvu zeBhola eziSebenziswa yiPneumaticzizinto ezibalulekileyo kwiintlobo ngeentlobo zezicelo zoshishino, zilawula ngokuthembekileyo ukuhamba kolwelo kunye neegesi. Ukuqonda indlela ezisebenza ngayo ezi zixhobo kubalulekile kwiinjineli, iingcali, kunye naye nabani na obandakanyekayo kuyilo kunye nokugcinwa kweenkqubo zolwelo. Eli nqaku liza kujonga ngokunzulu indlela esebenza ngayo iivalvu zebhola zepneumatic, izinto zazo, kunye nokusetyenziswa kwazo.

Yintoni iIvalvu yeBhola eSebenzayo yoMoya

Ivalvu yebhola eqhutywa ngomoya yivalvu esebenzisa i-actuator yomoya ukulawula ukuvulwa nokuvalwa kwevalvu yebhola. Ivalvu yebhola ngokwayo inediski engqukuva (ibhola) enomngxuma embindini webhola. Xa ivalvu ivuliwe, umngxuma uhambelana nomjelo wokuhamba, uvumela ulwelo okanye igesi ukuba idlule. Xa ivaliwe, ibhola iyajikeleza ukuvimba ukuhamba, inika isitywino esiqinileyo.

I-pneumatic actuator sisixhobo esiguqula umoya ocinezelweyo ube yintshukumo yoomatshini. Idla ngokuba nesilinda, i-piston, kunye nentonga yokudibanisa. Xa umoya unikezelwa kwi-actuator, utyhala i-piston, ethi yona ijikelezise ivalvu yebhola kwindawo oyifunayo.

Izinto ezisetyenziswa kwi-Pneumatic Ball Valve

1. Ivalvu yebhola: Inxalenye ephambili elawula ukuhamba kwamanzi. Iivalvu zebhola zingenziwa ngezinto ezahlukeneyo, kuquka intsimbi engatyiwayo, iplastiki okanye ithusi, kuxhomekeke kwindlela ezisetyenziswa ngayo.
2. Isixhobo sokuqhuba umoya: Le yindlela eqhuba ngayo ivalvu. Isenokuba yi-single acting (ifuna i-spring return) okanye i-double acting (isebenzisa uxinzelelo lomoya ukuvula nokuvala).
3. Inkqubo yolawulo: Ibandakanya izinzwa, iiswitshi, kunye nezilawuli ezilawula ukusebenza kwee-actuators ngokweemfuno zenkqubo.
4. Umthombo womoya: Umoya ocinezelweyo ngumthombo wamandla we-actuator. Umoya ocinezelweyo kufuneka ucoceke kwaye wome ukuqinisekisa ukusebenza kakuhle.
5. Iphedi yokuFakela: Umgangatho we-ISO 5211, le ndibano ikhusela i-actuator kwivalvu, iqinisekisa ukulungelelaniswa nokusebenza okufanelekileyo.

Isebenza njani ivalvu yebhola yepneumatic

Ukusebenza kwevalvu yebhola ye-pneumatic kunokwahlulwahlulwa ngamanyathelo aliqela:

1. Uqhagamshelo lomthombo womoya

Inyathelo lokuqala kukuqhagamshela i-pneumatic actuator kumthombo womoya ocinezelweyo. Unikezelo lomoya luhlala lulawulwa ukuqinisekisa uxinzelelo oluzinzileyo, nto leyo ibalulekileyo ekusebenzeni kwe-actuator.

2. Sebenzisa i-actuator

Xa inkqubo yolawulo ithumela isignali kwi-actuator, umoya ocinezelweyo ungena kwisilinda ye-actuator. Kwi-actuator esebenza kabini, umoya unikezelwa kwelinye icala le-piston, nto leyo ebangela ukuba ihambe kwicala elinye. Kwi-actuator esebenza kanye, xa uxinzelelo lomoya lukhutshwa, i-spring mechanism iya kubuyisela i-piston kwindawo yayo yokuqala.

3. Ukujikeleza kwebhola

Xa i-piston ihamba, iqhagamshelwe kwintonga, ejikeleza ivalvu yebhola. Ukujikeleza kwebhola kudla ngokuba ngama-90 degrees, ukusuka kwindawo evulekileyo ukuya kwindawo evaliweyo. Uyilo lwe-actuator luqinisekisa ukuba ibhola ihamba kakuhle nangokukhawuleza, nto leyo ekhokelela kwixesha lokuphendula ngokukhawuleza lolawulo lolwelo.

4. Ulawulo lweNdlela

Xa ivalvu yebhola ikwindawo efunekayo, ukuhamba kolwelo okanye igesi kuyavunyelwa okanye kuthintelwe. Itywina eliqinileyo elenziwe yivalvu yebhola liqinisekisa ukuvuza okuncinci, okwenza kube lukhetho olufanelekileyo lokulawula ukuhamba kwamanzi kwiindlela ezahlukeneyo zokusebenza.

5. Indlela yokuphendula ngempendulo

Iivalvu ezininzi zebhola ezisebenzisa umoya zixhotyiswe ngeendlela zokuphendula ezibonelela ngolwazi malunga nendawo yevalvu. Inkqubo yolawulo ingasebenzisa olu lwazi ukwenza uhlengahlengiso okanye ukubonisa umqhubi malunga nesimo sevalvu.

Iingenelo zePneumatic Ball Valve

Iivalvu zebhola ze-pneumatic zinezibonelelo ezininzi ngaphezu kwezinye iintlobo zeevalvu:

• Isantya: Zingavuleka zize zivale ngokukhawuleza, nto leyo ezenza zibe zilungele ukusetyenziswa apho kufuneka ulawulo lokuhamba kwamanzi ngokukhawuleza.
• Ichanekile: Ukukwazi ukulawula ngokuchanekileyo indawo yevalvu kuvumela ulawulo oluchanekileyo lokuhamba kwamanzi.
• UkuthembekaIinkqubo ze-pneumatic azinangxaki kangako yokungasebenzi kakuhle njengee-actuators zombane, ingakumbi kwiindawo ezinobungozi.
• ukhuseleko: Kwimeko yokungasebenzi kombane, ii-actuators zomoya zinokuyilwa ukuba zibuyele kwindawo ekhuselekileyo yokungasebenzi, nto leyo ephucula ukhuseleko lwenkqubo.
• UkuguquguqukaZingasetyenziswa kwiindlela ezahlukeneyo zokusetyenziswa kuquka ukunyanga amanzi, ukucutshungulwa kweekhemikhali, kunye neenkqubo ze-HVAC.

Ukusetyenziswa kweValve yeBhola yePneumatic

Iivalvu zebhola zomoya zisetyenziswa kakhulu kumashishini ahlukeneyo, kuquka:

• Ioyile kunye neGesi: Isetyenziselwa ukulawula ukuhamba kweoyile ekrwada, igesi yendalo kunye nezinye iihydrocarbon.
• Unyango lwamanzi: Kwiinkqubo apho kufuneka ulawulo oluchanekileyo lokuhamba kwamanzi ukuze kuhluzwe kwaye kulinganiswe iikhemikhali.
• Ukutya neZiselo: Ukulawula ukuhamba kolwelo kunye neegesi ngexesha lokucubungula kunye nokupakisha.
• Amayeza: Isetyenziselwa ukugcina iimeko ezicocekileyo kunye neenkqubo ezichanekileyo ngexesha lokwenziwa kwamayeza.
• I-HVAC: Isetyenziselwa ukulawula ukuhamba komoya kwiinkqubo zokufudumeza, zokungenisa umoya, kunye nezomoya opholileyo.

ukuququmbela

Ukuqonda indlela ezisebenza ngayo iivalvu zebhola zomoya kubalulekile kuye nabani na obandakanyeka kwiinkqubo zolawulo lolwelo. Ezi valve zidibanisa ukuthembeka kwee-actuators zomoya kunye nokusebenza kakuhle kweevalvu zebhola, nto leyo ezenza zibe lukhetho oludumileyo kwiindlela ezahlukeneyo zokusebenza kwemizi-mveliso. Ukukwazi kwazo ukulawula ukuhamba kolwelo ngokukhawuleza nangokuchanekileyo kuqinisekisa ukuba ziya kuqhubeka nokudlala indima ebalulekileyo kwiinkqubo zobunjineli zanamhlanje kunye nemveliso.
