Kwinkqubo yokusebenzisa i-valve ye-pneumatic, ngokuqhelekileyo kuyimfuneko ukumisela ezinye izinto ezincedisayo zokuphucula ukusebenza kwe-valve ye-pneumatic, okanye ukuphucula ukusebenza kokusetyenziswa kwe-valve ye-pneumatic. Izixhobo eziqhelekileyo zeevalvu zepneumatic ziquka: izihluzi zomoya, ivalve ye-solenoid ebuyela umva, ukutshintshwa komda, izithuba zombane, njl.njl. Kwitekhnoloji ye-pneumatic, izinto ezintathu zokucoca umthombo womoya wesihluzo somoya, ivalve yokunciphisa uxinzelelo kunye ne-oyile idityaniswe kunye, ebizwa ngokuba pneumatic iqhekeza kathathu. Isetyenziselwa ukungena kumthombo womoya ukuhlambulula kunye nokucoca isixhobo se-pneumatic kunye nokunciphisa uxinzelelo kwisixhobo sokubonelela ngexabiso lomthombo womoya Uxinzelelo lulingana nomsebenzi we-transformer yamandla kwisiphaluka.

Iindidi zezixhobo zevalve yepneumatic:

I-actuator yepneumatic esebenza kabini: Ulawulo lweendawo ezimbini zokuvula nokuvalwa kwevalvu. (Udlala kabini)

I-actuator ye-Spring-return: I-valve ivula okanye ivale ngokuzenzekelayo xa isiphaluka segesi yesiphaluka sinqunywe okanye singasebenzi kakuhle. (Umdlali omnye)

Ivalve ye-solenoid enye elawulwa ngombane: Ivalve ivula okanye ivale xa kunikezelwa amandla, kwaye ivale okanye ivule ivalve xa amandla elahlekile (iinguqulelo ezinobungqina bokudubula ziyafumaneka).

Ivalve ye-solenoid elawulwa kabini ngombane: Ivalve ivula xa ikhoyili enye inikwe amandla, kwaye ivalve ivale xa enye ikhoyili inikwe amandla. Inomsebenzi wememori (uhlobo olubonisa ubungqina luyafumaneka).

Umda wokutshintsha i-echo: Ukuhanjiswa komgama omde wesiginali yesikhundla sokutshintsha kwevalve (nohlobo lobungqina bokudubula).

Isikhundla sombane: Lungisa kwaye ulawule ukuhamba okuphakathi kwevalve ngokobungakanani bomqondiso wangoku (umgangatho we-4-20mA) (kunye nohlobo lobungqina bokuqhuma).

I-Pneumatic positioner: Lungisa kwaye ulawule ukuhamba okuphakathi kwevalve ngokobungakanani bophawu loxinzelelo lomoya (umgangatho we-0.02-0.1MPa).

Isiguquli sombane: Iguqula umqondiso wangoku ube ngumqondiso woxinzelelo lomoya. Isetyenziswa kunye ne-pneumatic positioner (kunye nohlobo lobungqina bokudubula).

Ukusetyenzwa komthombo womoya kathathu: kubandakanya ivalve yokunciphisa uxinzelelo lomoya, isihluzo, isixhobo senkungu yeoli, ukuzinzisa uxinzelelo, ukucoca kunye nokuthambisa iindawo ezihambayo.

Indlela yokusebenza ngesandla: Ulawulo oluzenzekelayo lunokwenziwa ngesandla phantsi kweemeko ezingaqhelekanga.

Ukukhethwa kwezixhobo zevalve yepneumatic:

Ivalve ye-pneumatic sisixhobo sokulawula esizenzekelayo esintsonkothileyo. Iqulunqwe ngamacandelo ahlukeneyo omoya. Abasebenzisi kufuneka benze ukhetho oluneenkcukacha ngokweemfuno zolawulo.

1. I-activator ye-pneumatic: ① uhlobo olubambekayo oluphindiweyo, ② uhlobo olulodwa olubambayo, ③ iinkcukacha zemodeli, ④ ixesha lesenzo.

2. Ivalve yeSolenoid: ① ivalve yokulawula enye, ② ivalve yesolenoid ephindwe kabini, ③ amandla ombane osebenzayo, ④ uhlobo lobungqina bokudubula

3. Ingxelo yoMqondiso: ① iswitsha ngoomatshini, ② iswitsha ekufutshane, ⑧ isiginali yemveliso yangoku, ④ usebenzisa amandla ombane, ⑤ uhlobo lobungqina bokudubula.

4. Isiphawuli: ① isilungisi sombane, ② indawo yomoya, ⑧ isignali yangoku, ④ isignali yoxinzelelo lomoya, ⑤ isiguquli sombane, ⑥ uhlobo lobungqina bokudubula.

5. Amalungu amathathu onyango lomthombo womoya: ① ​​ivalve yokunciphisa uxinzelelo lokucoca, ② isixhobo senkungu ye-oyile.

6. Indlela yokusebenza ngesandla.
