Ngokwesiqhelo kubalulekile ukucwangcisa izinto ezahlukeneyo ezincedisayo ngelixa iivalvu ze-pneumatic zisetyenziselwa ukuphucula ukusebenza kwazo okanye ukusebenza kakuhle. Izihluzi zomoya, iivalvu ezibuyisela umva iivalvu ze-solenoid, izitshixo zomda, iindawo zokubeka umbane, njl.ivalve yokunciphisa uxinzelelo, kunye ne-lubricator zizinto ezintathu zokulungiswa komthombo womoya ezidityaniswe njengeendawo ezintathu ze-pneumatic kwiteknoloji ye-pneumatic. Ezi zixhobo zisetyenziselwa ukuhlanjululwa kunye nokucoca umthombo womoya ongena kwisixhobo somoya kunye nokuwucinezela kumthombo womoya wesixhobo. I-transformer yamandla kwisiphaluka isebenza ngendlela elinganayo noxinzelelo.

Iindidi ezahlukeneyo zomoyaivalveizihlomelo

Ukuvula ivalve yeendawo ezimbini kunye nolawulo lokuvala nge actuator esebenza kabini yomoya. (ukungena kabini)

Xa isekethe yomoya yesekethe ivaliwe okanye isilela, iivalveiyakuzivula okanye ivale ngokuzenzekelayo enkosi kwi-spring return actuator. (Umdlalo olinganayo)

I-valve ye-solenoid enye: xa kusetyenziswe amandla, i-valve ivula okanye ivale; xa amandla esusiwe, ivalve ivula okanye ivale (uhlobo lobungqina bokudubula lunikezelwa).

Ivalve ye-solenoid ephindwe kabini enomsebenzi wenkumbulo kunye nolwakhiwo olungaqhambukayo oluvula xa ikhoyili enye inamandla kwaye ivale xa enye ikhoyili inikwe amandla.

Umda wesixhobo sempendulo yokutshintsha: nxibelelana nophawu lwendawo yokutshintsha ivelufa kumgama (iimodeli ezinobungqina bokudubula zikwakhona).

Isikhundla sombane: Ukulungelelanisa kunye nokulawula ukuhamba okuphakathi kwevalve (uhlobo lobungqina bokuqhuma luyafumaneka) ngokuhambelana nobukhulu bomqondiso wangoku (umgangatho we-4-20mA).

Isikhundla se-pneumatic: tshintsha kwaye ulawule ukuhamba okuphakathi kwevalve ngokuhambelana nobukhulu bophawu loxinzelelo lomoya (olubhalwe 0.02-0.1MPa).
Isiguquli sombane (imeko yobungqina bokudubula iyafumaneka): Guqula isignali yangoku ibe ngumqondiso woxinzelelo lomoya ukuze isetyenziswe nesikhundla somoya.

Ukuzinzisa ukunikezelwa komoya, ukucoceka, kunye nokuthambisa iindawo ezihambayo, unyango lomthombo womoya lubandakanya iinxalenye ezintathu: ivalve yokunciphisa uxinzelelo lomoya, isihluzi kunye ne-lubricator.

Indlela yokusebenza ngesandla: Kwiimeko ezingaqhelekanga, ulawulo oluzenzekelayo lunokukhutshwa ngesandla.

Ukukhetha izincedisi kwiivalvu zepneumatic:

Iivalvu zomoya zizixhobo ezintsonkothileyo zolawulo oluzenzekelayo ezenziwe ngamalungu ahlukeneyo omoya. Abasebenzisi kufuneka bakhethe ngononophelo ngokusekelwe kwiimfuno zolawulo.

1. Uhlobo oluphindwe kabini, uhlobo olulodwa, ukucaciswa kwemodeli, kunye nexesha lesenzo se-pneumatic actuators.

2. I-valve ye-solenoid yokulawula enye, i-valve ye-solenoid ephindwe kabini, i-voltage esebenzayo, kunye ne-valve ye-solenoid yobungqina bokuqhuma ziyafumaneka.

3. Ingxelo yesignali ibandakanya oku kulandelayo: ukutshintshwa komatshini, ukutshintshela ngokusondeleyo, umqondiso wangoku ophumayo, umbane wokusetyenziswa, kunye nohlobo lobungqina bokuqhuma.

4. I-Locator: 1 yombane, i-2 ye-pneumatic, i-8 yangoku, i-4 yoxinzelelo lomoya, i-5 converter yombane, kunye neentlobo ezi-6 zobungqina bokudubula.

5. Unyango lomthombo womoya onamacandelo amathathu: ii-lubricators ezimbini kunye ne-valve yokunciphisa uxinzelelo lokucoca.

6. Inkqubo yokusebenza ngesandla.
