Pneumatic Actuator Control Globe Valve
✧ Kufotokozera
valavu ya pneumatic control globe yomwe imadziwikanso kuti pneumatic cut-off valve, ndi mtundu wa actuator mu makina odzichitira, opangidwa ndi makina opangira mafilimu opangidwa ndi ma pneumatic ambiri kapena pisitoni yoyandama ndi valavu yowongolera, kulandira chizindikiro cha chida chowongolera, kuwongolera kudula. , kulumikiza kapena kusintha madzimadzi mu payipi ndondomeko. Lili ndi makhalidwe a dongosolo losavuta, kuyankha tcheru ndi zochita zodalirika. Itha kugwiritsidwa ntchito kwambiri mumafuta, mafakitale amafuta, zitsulo ndi magawo ena opanga mafakitale. Gwero la mpweya wa valavu yodulidwa ya pneumatic imafuna mpweya wophwanyidwa, ndipo sing'anga yomwe ikuyenda mu thupi la valve iyenera kukhala yopanda zonyansa ndi tinthu tating'ono tamadzi ndi gasi.
Silinda ya valavu ya pneumatic globe ndi chinthu chosasinthika, chomwe chimatha kugawidwa kukhala chinthu chimodzi ndikuchita kawiri molingana ndi momwe amachitira. Chopanga chimodzi chimakhala ndi kasupe wa silinda yobwezeretsanso, yomwe imakhala ndi ntchito yokonzanso yokha yotaya mpweya, ndiye kuti, pistoni ya silinda (kapena diaphragm) ikagwira ntchito masika, ndodo yokankhira silinda imayendetsedwa kubwerera koyambirira. malo a silinda (malo oyambirira a sitiroko). Silinda yochita kawiri ilibe kasupe wobwerera, ndipo kutsogola ndi kubwereranso kwa ndodo yokankhira kuyenera kudalira malo olowera ndi kutuluka kwa mpweya wa silinda. Pamene mpweya umalowa m'chipinda chapamwamba cha pisitoni, ndodo yokankhira imasunthira pansi. Pamene mpweya umalowa m'munsi mwa pistoni, ndodo yokankhira imayenda mmwamba. Chifukwa palibe kasupe wobwezeretsanso, silinda yochita kawiri imakhala ndi mphamvu zambiri kuposa silinda imodzi yokhala ndi m'mimba mwake, koma ilibe ntchito yokonzanso yokha. Mwachiwonekere, malo osiyanasiyana odyetsera amachititsa kuti putter azisuntha mbali zosiyanasiyana. Pamene mpweya wolowa m'malo ali kumbuyo kwa ndodo yokankhira, kulowetsedwa kwa mpweya kumapangitsa kuti ndodo ipite patsogolo, njira iyi imatchedwa "positive cylinder". M'malo mwake, pamene mpweya wolowetsa mpweya uli kumbali imodzi ya ndodo yokankhira, mpweya wolowa umapangitsa ndodo yokankhira kumbuyo, yomwe imatchedwa reaction cylinder. Valavu ya pneumatic globe chifukwa chofunikira kwambiri kutaya ntchito yoteteza mpweya, nthawi zambiri amagwiritsa ntchito silinda imodzi yokha.

✧ Ubwino wa Pneumatic Actuator Control Globe Valve
Panthawi yotsegulira ndi kutseka kwa valve yachitsulo yopangidwa ndi zitsulo, chifukwa kukangana pakati pa diski ndi kusindikiza pamwamba pa thupi la valve ndi kochepa kuposa kwa valve yachipata, imakhala yosagwira ntchito.
Kutsegula kapena kutseka kwa tsinde la valve ndi kochepa kwambiri, ndipo kumakhala ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valve kumakhala kofanana ndi kugunda kwa valve disc, ndikoyenera kwambiri kusintha. wa mlingo wotuluka. Choncho, valavu yamtunduwu ndi yoyenera kwambiri kudulidwa kapena kuwongolera ndi kugwedeza.
