Yintoni iValve yeBhola yePneumatic

Iivalvu zebhola zomoya, ezaziwa ngokuba ziivalvu zebhola eziqhutywa ngumoya, zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo zolawulo lolwelo lwemizi-mveliso. Uyilo lwazo oluncinci, ukusebenza ngokukhawuleza, kunye nokutywinwa okuthembekileyo kuzenza zilungele uluhlu olubanzi lwezicelo. Eli nqaku libonelela ngesishwankathelo esibanzi seevalvu zebhola ezisebenzisa umoya, kubandakanya uyilo lwazo, umgaqo wokusebenza, iintlobo, iingenelo, usetyenziso, ukufakelwa, ukugcinwa, kunye nokusombulula iingxaki. Ekugqibeleni, abafundi baya kuba nokuqonda okucokisekileyo kolu hlobo lwevalvu oluguquguqukayo.

1. Intshayelelo kwiivalvu zebhola zePneumatic

Iivalvu zebhola zomoya ziivalvu ezisebenzisa umoya ocinezelweyo njengomthombo wamandla ukulawula ukuvulwa nokuvalwa kwevalvu. Ziqulathe umzimba wevalvu yebhola, ibhola (njengento yokuvala ivalvu), i-actuator yomoya, kunye nezinye izixhobo ezinxulumene nayo. Ibhola inomngxuma ojikelezayo okanye indlela edlula kwi-axis yayo, kwaye ngokujikelezisa ibhola ngama-90 degrees, ukuhamba kwayo kungavulwa ngokupheleleyo, kuvalwe, okanye kugoqwe.

2. Uyilo kunye noMgaqo-siseko wokuSebenza

Uyilo lwevalvu yebhola yomoya luvela kwivalvu yeglobe kodwa luphucuke kakhulu. Izinto eziphambili ziquka:

Umzimba weValve: Ngokwesiqhelo yenziwe ngentsimbi ephosiweyo, intsimbi engatyiwayo, okanye ezinye izinto ezifanelekileyo, umzimba wevalvu ugcina ibhola kwaye ubonelela ngendlela yokuhamba.

Ibhola: Iskwere esingenanto esinomngxuma ojikelezayo. Xa ijikeleziswa ngama-90 degrees, umngxuma uhambelana neendawo zokungena kunye nezokuphuma ukuze kuvunyelwe ukuhamba, okanye uhambelana gwenxa ukuze uvale ukuhamba.

Isixhobo sokuqhuba umoya: Le nxalenye iguqula umoya ocinezelweyo ube yintshukumo yoomatshini ukuze ujikeleze ibhola. Iqulathe isilinda, i-piston, kunye nentonga yokudibanisa.

Izitywino: Izitywino zibalulekile ekuthinteleni ukuvuza. Ngokwesiqhelo zenziwe ngezinto ze-elastomeric okanye iintsimbi kwaye zifumaneka phakathi kwebhola kunye nomzimba wevalvu.

Umgaqo wokusebenza ulula: xa umoya ocinezelweyo unikezelwa kwi-actuator, i-piston iyashukuma, nto leyo ebangela ukuba intonga yokudibanisa ijikeleze ibhola. Oku kujikelezisa kulungelelanisa okanye kulungelelanisa umngxuma odlulayo kunye neendawo zokungena kunye nezokuphuma, ngaloo ndlela kulawula ukuhamba kwamanzi.

3. Iintlobo zeeValve zeBhola zePneumatic

Iivalvu zebhola ze-pneumatic zinokuhlulwa ngokweekhrayitheriya ezahlukeneyo:

Ulwakhiwo: Zingaba ziindlela ezimbini, ezintathu, okanye enye. Iivalvu ezimbini kulula ukuzigcina, ngelixa iivalvu ezineenxalenye enye zibonelela ngokusebenza ngcono kokutywina.

Izinto zokutywina: Iivalvu ezitywiniweyo ezithambileyo zisebenzisa izixhobo ze-elastomeric zokuvala, ezifanelekileyo ukusetyenziswa ngoxinzelelo oluphantsi kunye nokungaboliyo. Iivalvu ezitywiniweyo eziqinileyo zisebenzisa ukuvala ukusuka kwisinyithi ukuya kwisinyithi, ezifanelekileyo ukusetyenziswa ngoxinzelelo oluphezulu kunye nobushushu obuphezulu.

Indlela Yokuhamba: Iivalvu ezithe tye, ezindlela zintathu, kunye nee-engile ziyafumaneka, kuxhomekeke kwiimfuno zendlela yokuhamba.

Uhlobo lwe-Actuator: Ii-actuator ezisebenza kabini zisebenzisa umoya ocinezelweyo ukuhambisa i-piston kuzo zombini iindlela, ngelixa ii-actuator ezisebenza kanye zixhomekeke ekubuyeni kwentwasahlobo kwicala elinye.
