Kubalulekile ngokwesiqhelo ukuhlela izinto ezahlukeneyo ezincedisayo ngelixa kusetyenziswa iivalvu zomoya ukuze kuphuculwe ukusebenza kwazo okanye ukusebenza kwazo kakuhle. Izihluzi zomoya, iivalvu zesolenoid ezibuyisela umva, iiswitshi zomda, ii-electrical positioners, njl.njl. zizixhobo eziqhelekileyo zeevalvu zomoya. Isihluzi somoya,ivalvu yokunciphisa uxinzelelo, kunye ne-lubricator ziinxalenye ezintathu zokucubungula imithombo yomoya ezidityaniswe njengeenxalenye ezintathu zomoya kwitekhnoloji yomoya. Ezi nxalenye zisetyenziselwa ukucoca nokucoca umthombo womoya ongena kwisixhobo somoya kunye nokuwukhulula kumthombo womoya olinganisiweyo wesixhobo. I-power transformer kwisekethe isebenza ngendlela efanayo noxinzelelo.

Iintlobo ezahlukeneyo ze-pneumaticivalvuizincamathiselo

Ulawulo lokuvula nokuvala ivalvu eneendawo ezimbini olune-actuator ye-pneumatic esebenza kabini. (i-entender ephindwe kabini)

Xa isekethe yomoya yesekethe ivaliwe okanye ingaphumeleli,ivalvuiza kuvula okanye ivale ngokuzenzekelayo ngenxa ye-actuator yokubuyisela intwasahlobo. (Isebenza ngendlela efanayo)

Ivalvu yesolenoid enye: xa kusetyenziswa umbane, ivalvu iyavula okanye ivale; xa umbane ususiwe, ivalvu iyavula okanye ivale (uhlobo olungenakuqhuma lunikezelwa).

Ivalvu yesolenoid ephindwe kabini enomsebenzi wememori kunye nolwakhiwo olungenakuqhuma oluvula xa ikhoyili enye inikwe amandla kwaye ivale xa enye ikhoyili inikwe amandla.

Isixhobo sokuphendula ngomda kwiswitshi: thetha ngesignali yesikhundla seswitshi sevalvu kumgama othile (nazo iimodeli ezithintela ukuqhuma ziyafumaneka).

I-Electric positioner: Ilungisa kwaye ilawula ukuhamba okuphakathi kwevalvu (uhlobo olungenakuqhuma luyafumaneka) ngokuhambelana nobukhulu besignali yangoku (eqhelekileyo yi-4-20mA).

I-Pneumatic positioner: tshintsha kwaye ulawule ukuhamba okuphakathi kwevalvu ngokuhambelana nobukhulu besignali yoxinzelelo lomoya (ebhalwe nge-0.02-0.1MPa).
Isiguquli sombane (uhlobo olungenakuqhuma luyafumaneka): Guqula isignali yangoku ibe sisignali yoxinzelelo lomoya ukuze isetyenziswe ne-pneumatic positioner.

Ukuze kuzinziswe unikezelo lomoya, ukucoca, kunye nokuthambisa iindawo ezihambayo, unyango lomthombo womoya luquka iindawo ezintathu: ivalvu yokunciphisa uxinzelelo lomoya, isihluzi, kunye ne-lubricator.

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

Ukukhetha izixhobo zeevalvu zomoya:

Iivalvu zomoya zizixhobo zokulawula ngokuzenzekelayo ezintsonkothileyo ezenziwe ngamacandelo ahlukeneyo omoya. Abasebenzisi kufuneka bakhethe ngononophelo ngokusekelwe kwiimfuno zolawulo.

1. Uhlobo olusebenza kabini, uhlobo olusebenza kanye, iinkcukacha zemodeli, kunye nexesha lokusebenza kwee-actuators zomoya.

2. Ivalvu yesolenoid yokulawula enye, ivalvu yesolenoid yokulawula kabini, ivolthi yokusebenza, kunye neevalvu zesolenoid zohlobo olungenakuqhuma ziyafumaneka.

3. Impendulo yesignali ibandakanya oku kulandelayo: iswitshi yoomatshini, iswitshi yokusondela, isignali yangoku yokuphuma, ivolthi yokusetyenziswa, kunye nohlobo olungenakuqhuma.

4. Indawo yokukhangela: umbane omnye, umoya ohambayo o-2, umbane o-8, uxinzelelo lomoya olu-4, i-converter yombane e-5, kunye neentlobo ezi-6 ezithintela ukuqhuma.

5. Unyango lomthombo womoya olunezixhobo ezintathu: ii-lubricators ezimbini kunye nevalvu yokunciphisa uxinzelelo lwesihluzo.

6. Indlela yokusebenza ngesandla.
