Ukuthuthukisa Ukulawula Ukugeleza Nge-Pneumatic 3-Piece Ball Valves

Ukwakhiwa okuyisisekelo kwe-valve yebhola ye-pneumatic yezingxenye ezintathu

Ivalvu yebhola eneziqephu ezintathu yomoya inezingxenye ezintathu eziyinhloko: umzimba we-valve, ibhola kanye ne-actuator yomoya. Umzimba we-valve uklanywe ngezingcezu ezintathu ukuze ulungiswe kalula futhi ushintshwe. Ibhola liphakathi nendawo ye-valve futhi linembobo ephumela. Lapho ibhola lijikeleza ama-degree angu-90, imbobo iqondaniswe noma i-perpendicular esiteshini sokugeleza ukuze kuzuzwe isimo esivulekile noma esivaliwe. I-actuator ye-pneumatic inesibopho sokushayela ukujikeleza kwebhola nokubona ukuvulwa nokuvala okusheshayo kwe-valve ngokusebenzisa amandla omoya ocindezelwe.

Amaphoyinti ezobuchwepheshe okuthola ukulawula ukugeleza okunembayo

1. Ukunemba kwebhola ukucutshungulwa

Ukucutshungulwa okunembayo kwebhola kuyisihluthulelo sokuqinisekisa ukusebenza kokuvala kwe-valve kanye nokunemba kokulawula ukugeleza. Ingaphezulu lebhola kufanele libe bushelelezi kakhulu futhi libe nesimo sejometri esinembile ukuze kuqinisekiswe ukufana okuphelele nesihlalo se-valve. Ngaphezu kwalokho, usayizi nokuma kwembobo yebhola kuthinta ngokuqondile i-coefficient (ivelu ye-Cv), ngakho-ke idinga ukubalwa ngokunembile futhi icutshungulwe.

2. Idizayini yesihlalo sevalvu ephezulu

Ukwakhiwa kwesihlalo se-valve nakho kuthinta ukunemba kokulawula ukugeleza. Izihlalo zamavalvu ezisezingeni eliphezulu zihlinzeka ngomfutho wokuvala okufanayo, zivimbela ukuvuza kwemidiya, futhi ziqinisekise ukuthi i-valve yebhola ingagcina ukusebenza kahle kokuvala ngemva kokusetshenziswa isikhathi eside.

3. Ukusebenza kwama-actuator womoya

Ukulawulwa okunembile kwama-actuator womoya kuyimfuneko yokulawula ukugeleza okusheshayo nokunembile. I-actuator kufanele ikwazi ukunikeza i-torque eyanele ukushayela ibhola, futhi ngesikhathi esifanayo idinga isivinini sokuphendula esisheshayo nokulawula okunembile kwendawo yebhola.

4. Uhlelo lwempendulo yesikhundla

Ukusetshenziswa kwesistimu yempendulo yesikhundla, njengokushintshwa komkhawulo noma inzwa, kungaqapha ukuma kwebhola ngesikhathi sangempela ukuze kuqinisekiswe ukunemba nokuphindaphinda kwe-actuator yomoya. Lokhu kubaluleke kakhulu ekuzuzeni ukulawulwa kokugeleza okuhle.

5. Ukuhlanganiswa kwezinhlelo zokulawula

Ukuhlanganisa ama-valve ebhola aneziqephu ezintathu ze-pneumatic nezinhlelo zokulawula ezithuthukile kungafinyelela amasu okulawula ukugeleza ayinkimbinkimbi. Ngokusebenzisa imishini ezishintshayo njenge-PLC (isilawuli se-logic esihlelekayo) noma i-DCS (uhlelo lokulawula olusabalalisiwe), ukuvulwa kwamavalvu kungalawulwa ngokunembile ukuze kuzuzwe ukulungiswa kahle kokugeleza.

Izinyathelo zokuthuthukisa

1. Ukukhetha izinto ezibonakalayo

Ukukhetha impahla efanele kubalulekile ukuze kuthuthukiswe ukumelana nokugqokwa, ukumelana nokugqwala nokusebenza kokuvala i-valve. Ukukhetha izinto ezifanele zebhola nezihlalo, njengensimbi engagqwali, insimbi ye-carbon noma ama-alloys akhethekile, ngokuya ngezimo ezihlukene zokusebenza kungathuthukisa ukwethembeka nokuphila kwesevisi ye-valve.

2. Isu lokunakekela

Ukugcinwa njalo nokuhlolwa kwesimo se-valve kanye nokushintshwa ngesikhathi kwezingxenye ezigugile kungaqinisekisa ukuthi i-valve ihlale igcina isimo esingcono kakhulu sokusebenza.

3. Ukuvumelana nezimo zemvelo

Uma ucabangela izici ezifana nezinga lokushisa, ingcindezi, kanye nezici eziphakathi kwendawo yokusebenza ye-valve, khetha imiklamo efanele kanye nezinto zokwakha ukuze uqinisekise ukuzinza nokuthembeka kwe-valve endaweni ethile.

I-valve yebhola eneziqephu ezintathu zepneumatic ifinyelela ukulawula ukugeleza okunembile ngokucubungula ibhola okunembayo, idizayini yezihlalo zekhwalithi ephezulu, i-actuator ye-pneumatic esebenza kahle kakhulu, isistimu yempendulo yesimo esinembile kanye nokuhlanganiswa kwesistimu yokulawula okuthuthukisiwe. Ngokuthatha izinyathelo ezinengqondo zokuthuthukisa, ukusebenza kwe-valve kungathuthukiswa ngokwengeziwe ukuze kuhlangatshezwane nezidingo eziqinile zemboni yesimanje yokulawula ukugeleza.
