Pogwiritsa ntchito valavu ya pneumatic, nthawi zambiri zimakhala zofunikira kukonza zigawo zina zothandizira kuti ziwongolere bwino ntchito ya valavu ya pneumatic, kapena kupititsa patsogolo ntchito yogwiritsira ntchito valavu ya pneumatic. Zida zodziwika bwino za ma valve pneumatic zikuphatikizapo: zosefera mpweya, kutembenuza ma valve a solenoid, kusintha malire, malo amagetsi, ndi zina zotero. pneumatic katatu chidutswa. Amagwiritsidwa ntchito polowetsa mpweya kuti ayeretse ndi kusefa chida cha pneumatic ndikuchepetsa kupanikizika kwa chida choperekera mpweya wovomerezeka Kupanikizika kuli kofanana ndi ntchito ya transformer yamagetsi mu dera.

Mitundu ya zida za ma valve pneumatic:

Woyendetsa pneumatic wochita kawiri: Kuwongolera kwapawiri kwa ma valve otsegula ndi kutseka. (Kuchita kawiri)

Makina obwezeretsa kasupe: Vavu imatsegula kapena kutseka yokha pamene dera la gasi lozungulira likudulidwa kapena kulephera. (Single acting)

Valavu imodzi yamagetsi yoyendetsedwa ndi solenoid: Valavu imatsegula kapena kutseka mphamvu ikaperekedwa, ndikutseka kapena kutsegula valavu pamene mphamvu itayika (matembenuzidwe ophulika alipo).

Vavu yoyendetsedwa ndi solenoid pawiri: Vavu imatsegulidwa pomwe koyilo imodzi yapatsidwa mphamvu, ndipo valavu imatseka pomwe koyilo ina yapatsidwa mphamvu. Ili ndi ntchito yokumbukira (mtundu waumboni wakale ulipo).

Limit switch echo: Kutumiza mtunda wautali kwa chizindikiro chosinthira cha valve (ndi mtundu wotsimikizira kuphulika).

Poyimitsa magetsi: Sinthani ndikuwongolera kuyenda kwapakati kwa valavu molingana ndi kukula kwa chizindikiro chomwe chilipo (muyezo wa 4-20mA) (ndi mtundu wotsimikizira kuphulika).

Pneumatic positioner: Sinthani ndi kuwongolera kuyenda kwapakati kwa valavu molingana ndi kukula kwa chizindikiro cha mpweya (wokhazikika 0.02-0.1MPa).

Chosinthira magetsi: Imatembenuza siginecha yapano kukhala siginecha yamagetsi. Amagwiritsidwa ntchito limodzi ndi choyimitsira pneumatic (ndi mtundu wotsimikizira kuphulika).

Kukonza magwero a mpweya wa magawo atatu: kuphatikiza valavu yochepetsera mpweya, fyuluta, chipangizo chamafuta, kukhazikika kwamphamvu, kuyeretsa ndi kuthira zigawo zosuntha.

Makina ogwiritsira ntchito pamanja: Kuwongolera zokha kumatha kuyendetsedwa pamanja pazovuta.

Kusankhidwa kwa zida za valve pneumatic:

Valavu ya pneumatic ndi chida chowongolera chodziwikiratu. Zimapangidwa ndi mitundu yosiyanasiyana ya pneumatic. Ogwiritsa ntchito ayenera kusankha mwatsatanetsatane malinga ndi zofunikira zowongolera.

1. Pneumatic actuator: ① machitidwe awiri, ② mtundu umodzi wa sewero, ③ zachitsanzo, ④ nthawi yochita.

2. Solenoid vavu: ① single control solenoid valve, ② wapawiri kulamulira solenoid valavu, ③ voteji ntchito, ④ mtundu kuphulika-umboni

3. Ndemanga za siginecha: ① makina osinthira, ② kusintha kwapafupi, ⑧ chizindikiro chapano, ④ kugwiritsa ntchito magetsi, ⑤ mtundu wosaphulika

4. Positioner: ① magetsi poyika, ② pneumatic positioner, ⑧ chizindikiro panopa, ④ mpweya kuthamanga chizindikiro, ⑤ magetsi converter, ⑥ mtundu wosaphulika.

5. Zigawo zitatu zochizira mpweya: ① ​​valavu yochepetsera zosefera, ② chipangizo chamafuta.

6. Njira yogwiritsira ntchito pamanja.
