Valavu ya mpira wa pneumatic ya magawo awiri

Valavu ya mpira wa pneumatic ya magawo awiri imagwiritsidwa ntchito makamaka powongolera zokha mumakina okweza ndi kutsitsa, ndipo ndi yoyenera kugwiritsa ntchito pomwe pali zofunikira zomveka bwino pakutsegula ndi kutseka komanso momwe chitetezo chilili. Kudzera mu mfundo ya magawo awiri, vavu imakwaniritsa kuwongolera kotsegulira ndi kutseka, komwe kumathandiza kukonza chitetezo ndi kulamulira kwa njira yokwezera ndi kutsitsa.

Choyatsira ma valve chingagwiritse ntchito choyatsira ma pneumatic cha malo atatu kapena kuyendetsedwa ndi chowonjezera chamagetsi chogawanika. Pakugwira ntchito, valavu imatha kumaliza kutsegula koyamba ndi kutsegula kwathunthu mu seti yokhazikika, kapena kutseka mu seti yosiyana, yomwe imagwiritsidwa ntchito kuchepetsa mphamvu ya nthawi yomweyo ya sing'anga ndikuchepetsa katundu pamapaipi ndi zida zina zogwirizana nazo, zoyenera kunyamula ndi kutsitsa zinthu zamadzimadzi kapena mpweya.

Vuto la valavu nthawi zambiri limakhala lotsekedwa. Ngati mpweya kapena chizindikiro chowongolera sichikuyenda bwino, valavu imatha kutseka yokha kuti isatuluke madzi pang'ono ndikukwaniritsa zofunikira zachitetezo panthawi yokweza ndi kutsitsa. Vavuyi imathandizira ntchito yakomweko komanso yowongolera kutali, ndipo imatha kukonzedwa ndi ma switch oyendera, ma signal olumikizirana, ndi ma module olumikizirana, zomwe zimapangitsa kuti zikhale zosavuta kulumikizana ndi machitidwe a DCS kapena PLC kuti aziwunika momwe zinthu zilili komanso kuyang'anira pakati.

Nthawi yogwirira ntchito ya valavu ikhoza kusankhidwa ndikusinthidwa malinga ndi momwe ntchito ikuyendera, zomwe zingakwaniritse zofunikira pakukweza ndi kutsitsa katundu bwino komanso kuganizira kukhazikika kwa ntchito ya dongosolo. Ikagwiritsidwa ntchito ngati valavu yodziletsa yokweza ndi kutsitsa katundu, valavu ya mpira wa pneumatic ya magawo awiri imatha kuonetsetsa kuti ntchitoyo ndi yotetezeka pamene ikukweza kudalirika ndi kusinthasintha kwa kayendetsedwe ka malo.

- Yoyenera kulamulira yokha pakukweza ndi kutsitsa makina

- Njira yotsegulira ndi kutseka ya magawo awiri, njira yowongolera zochita

- Yokhazikika ndi actuator ya pneumatic ya malo atatu kapena chowonjezera chamagetsi chogawanika

- Vuto nthawi zambiri limatsekedwa

- Imathandizira kuwongolera kwanuko komanso kutali

- Yokhazikika ndi ntchito zolumikizirana zakutali komanso mayankho a momwe zinthu zilili

- Nthawi yogwira ntchito ingasankhidwe malinga ndi momwe ntchito ikuyendera

- Makina odzaza ndi kutsitsa zinthu zamadzimadzi kapena gasi

- Mapaipi osungira ndi kunyamula zinthu

- Zochitika ndi zofunikira zachitetezo pakutsegula ndi kutseka

- Kuwongolera zokha ndi machitidwe olumikizirana
