Yintoni iValve yeBhola yomoya: Isikhokelo esiBanzi

Yintoni iValve yeBhola yomoya

Iivalvu zebhola yepneumatic, ekwaziwa ngokuba ziivalvu zebhola ezisebenza emoyeni, ngamacandelo ayimfuneko kwiinkqubo ezahlukeneyo zokulawula ulwelo lwamashishini. Uyilo lwabo oludityanisiweyo, ukusebenza ngokukhawuleza, kunye nokutywinwa okuthembekileyo kubenza balungele uluhlu olubanzi lwezicelo. Eli nqaku linika inkcazo ebanzi yeevalvu zebhola ze-pneumatic, kubandakanywa noyilo lwazo, umgaqo wokusebenza, iindidi, iingenelo, izicelo, ukufakela, ukugcinwa, kunye nokuxazulula iingxaki. Ekugqibeleni, abafundi baya kuba nokuqonda ngokucokisekileyo kolu hlobo lwevalve lusebenza ngeendlela ezininzi.

1. Intshayelelo kwiiValuvu zeBhola yePneumatic

Iivalvu zebhola ye-pneumatic zizivalo ezisebenzisa umoya ocinezelweyo njengomthombo wamandla olawula ukuvuleka nokuvalwa kwevalve. Ziquka umzimba wevalve yebhola, ibhola (njengento yokuvala ivalve), i-actuator yomoya, kunye nezixhobo ezinxulumeneyo. Ibhola inesetyhula nge-hole okanye idlula kwi-axis yayo, kwaye ngokujikeleza ibhola i-90 degrees, ukuhamba kunokuvulwa ngokupheleleyo, kuvaliwe, okanye kugxininiswe.

2. Uyilo kunye noMgaqo wokuSebenza

Uyilo lwevalve yebhola ye-pneumatic luthathwe kwivalve yeglowubhu kodwa ngophuculo olubonakalayo. Amacandelo aphambili aquka:

Umzimba weValve: Ngokuqhelekileyo yenziwe ngentsimbi etyhidiweyo, insimbi engenasici, okanye ezinye izinto ezifanelekileyo, umzimba wevalve ugcina ibhola kwaye unikezela indlela yokuhamba.

Ibhola: Ingqukuva enomngxuma ojikelezayo. Xa ujikeleziswa ngamadigri angama-90, umngxuma ulungelelaniswa ne-inlet kunye ne-outlet port ukuvumela ukuhamba, okanye ukungahambi kakuhle ukuvala ukuhamba.

IActuator yomoya: Eli candelo liguqula umoya ocinezelweyo ube yintshukumo yomatshini ukujikelezisa ibhola. Iqukethe i-cylinder, ipiston, kunye nentonga yokudibanisa.

Amatywina: Amatywina abalulekile ekuthinteleni ukuvuza. Ngokuqhelekileyo zenziwe ngezinto ze-elastomeric okanye iintsimbi kwaye zibekwe phakathi kwebhola kunye nomzimba wevalvu.

Umgaqo wokusebenza uqondile: xa umoya oxinyiweyo unikezelwa kwi-actuator, i-piston ihamba, ibangela ukuba intonga yokudibanisa ijikeleze ibhola. Olu jikelezo lulungelelanisa okanye lulungelelanise kakubi umngxuma wokuphumela kunye nendawo yokungena nokuphuma, ngaloo ndlela ilawula ukuhamba.

3. Iindidi ze-Pneumatic Ball Valves

Iivalvu zebhola yepneumatic zinokuhlelwa ngokusekelwe kwiikhrayitheriya ezahlukeneyo:

Ulwakhiwo: Zinokuba ngamaqhekeza amabini, amaqhekeza amathathu, okanye idizayini enye. Iivalve ezimbini-ezimbini kulula ukuzigcina, ngelixa iivalve zesiqwenga esinye zibonelela ngokusebenza ngcono kokutywina.

Izinto zokutywina: Iivalve ezitywiniweyo ezithambileyo zisebenzisa izinto ze-elastomeric zokutywinwa, ezifanelekileyo kwi-low-pressure and non-corrosive applications. Iivalve ezivaliweyo zisebenzisa ukutywinwa kwesinyithi ukuya kwintsimbi, ifanelekile kwizicelo zoxinzelelo oluphezulu kunye nobushushu obuphezulu.

Indlela yokuhamba: Ngokuthe tye, iindlela ezintathu, kunye neevalve ze-angle ziyafumaneka, kuxhomekeke kwiimfuno zendlela yokuhamba.

Uhlobo lweActuator: Ii-actuator ezisebenza kabini zisebenzisa umoya ocinezelweyo ukuhambisa ipiston kumacala omabini, ngelixa ii-activators ezibambeleyo zixhomekeke ekubuyeni kwentwasahlobo kwicala elinye.

4. Izinto eziluncedo kwi-Pneumatic Ball Valves

Iivalvu zebhola yepneumatic zibonelela ngeenzuzo ezininzi ngaphezulu kwezinye iindidi zevalvu:
