Iingenelo ezi-5 eziphezulu zokusebenzisa iValve yeBhola eneeMoto kwiZicelo zeShishini

Kwi-automation yemizi-mveliso yanamhlanje, iivalvu zebhola ezinenjini zidlala indima ebalulekileyo ekuphuculeni ukusebenza kakuhle kwenkqubo kunye nokuchaneka kolawulo. Ezi zixhobo zikwabizwa ngokuba ziivalvu zebhola zombane, zibonelela ngesisombululo esithembekileyo sokulawula ukuhamba kolwelo kwiindlela ezininzi zokusebenza. Apha ngezantsi, sihlola iingenelo eziphambili zokusebenzisa iivalvu zebhola ezinenjini kwaye sichaze ukuba kutheni zisiba sisisombululo sevalvu esithandwayo kwiindawo zoshishino.

Yintoni iValve yeBhola eneeMoto?

AIvalve yeBhola eneeMotoyivalvu ezenzekelayo esebenzisa i-actuator yombane ukujikeleza ibhola ngaphakathi kwivalvu. Olu jikelezo luvumela okanye luthintele ukuhamba kwemidiya, okwenza ukuba ilungele ukusetyenziswa okufuna ukuvalwa okanye ukulawulwa kokuhamba. Ezi valve zisetyenziswa kakhulu kwiinkqubo ze-automation zoshishino apho ulawulo olukude noluchanekileyo luyimfuneko.

Ulwakhiwo lweValve yeBhola yoMbane

Ivalvu yebhola yombane ineenxalenye ezimbini eziphambili: i-actuator yombane kunye nendibano yevalvu yebhola.

• Isixhobo sombane:Ifumana imiqondiso yokulawula kwaye iqhuba injini yombane ukuze ivelise intshukumo ejikelezayo.

•Indibano yeValve yeBhola:Ibandakanya umzimba wevalvu, ibhola, isihlalo, kunye nesiqu. Umzimba wevalvu wenza iqokobhe langaphandle elinomjelo wangaphakathi wokuhamba. Ibhola isebenza njengento yokuvala, ijikeleza ngama-90 degrees ukuvula okanye ukuvala indlela yokuhamba. Isihlalo sevalvu sisebenza njenge-gasket yokuvala ukuthintela ukuvuza xa ivalvu ivaliwe.

Isebenza njani iValve yeBhola eneeMoto?

Umgaqo wokusebenza kwevalvu yebhola eqhutywa yimoto ulula. Xa i-actuator ifumana isignali evela kwinkqubo yokulawula, iyenza isebenze imoto. Ukujikeleza kwemoto kudluliselwa ngesixhobo segiya (njengegiya ye-worm) ukuze ijike ibhola.

• Xa imbobo yebhola ihambelana nombhobho, ulwelo luhamba ngokukhululekileyo.

• Xa ijikeleziswa ngama-90 degrees, ibhola ivala ukuhamba kwayo.
Le ndlela ilula kodwa esebenzayo ivumela ulawulo oluvulekileyo nolucacileyo kunye nolawulo lokuhamba kwamanzi.

Isishwankathelo sezicelo zoshishino

Iivalvu zebhola zombane zinokuguquguquka okuninzi kwaye zingasetyenziswa kumacandelo amaninzi emizi-mveliso nakwiindawo ezingqongileyo. Zifanelekile kubushushu obuphezulu/obuphantsi, uxinzelelo oluphezulu/oluphantsi, ulwelo olubolayo, imidiya exineneyo, nokunye.
Umzekelo:
