Mu msonkhano wa Jinbin, 12 flangevalavu butterflyya DN450 specifications amaliza ntchito yonse yopanga. Pambuyo poyang'anitsitsa bwino, adapakidwa ndikutumizidwa komwe akupita. Gulu ili la mavavu agulugufe lili ndi magulu awiri: pneumaticvalavu ya butterflyndi zida nyongolotsi flanged manual butterfly valve. Adzapangidwa makamaka kuti azigwiritsidwa ntchito m'mafakitale otayira gasi ndipo amatha kugwira ntchito mokhazikika pamalo ogwirira ntchito a ≤80 ℃.

Thevalavu ya butterfly pneumaticopangidwa nthawi ino amakonzedwa ndi njira zolondola kwambiri. Malo osindikizira a mbale ya valve adachitidwa chithandizo chapadera kuti atsimikizire kukana kwa dzimbiri komanso kusindikiza kusindikiza pamagetsi otulutsa mpweya. Zogulitsa zonse zadutsa mayeso okana kukakamiza, kuzindikira kutayikira komanso kuyeserera kwanyengo yotentha kwambiri. Zizindikiro zonse zimagwirizana kwathunthu ndi miyezo yamakampani, kupereka zitsimikizo zodalirika zoyendetsera ntchito yotetezeka ya gasi wowononga. 

Monga gulu lofunikira la kutumiza uku, ma valve agulugufe opangidwa ndi pneumatic flanged ali ndi udindo waukulu pakuwongolera madzimadzi m'mafakitale chifukwa chaubwino wawo wodabwitsa. Ubwino wake waukulu ukuwonetsedwa m'magawo atatu: Choyamba, ili ndi liwiro loyankha mwachangu. Poyendetsa makinawo ndi mpweya woponderezedwa, amatha kukwaniritsa kutsegula ndi kutseka kwa millisecond, ndipo amatha kuyankha mwamsanga kusintha kwamphamvu kwa mpweya wotulutsa mpweya. Chachiwiri, ili ndi digiri yayikulu yophatikizira yodzichitira yokha, imathandizira kulumikizana ndi dongosolo lowongolera la PLC, ndipo imatha kuyika patali sinthani Angle kuti ikwaniritse malamulo oyendetsera bwino. Chachitatu, mtengo wokonza ndi wotsika. The pneumatic actuator ili ndi dongosolo losavuta komanso palibe vuto la kutentha kwa injini. M'malo ogwirira ntchito pansi pa 80 ℃, moyo wake wautumiki ndi wotalika kuposa 30% kuposa wa valve yamagetsi. 

Pankhani ya zochitika zogwiritsira ntchito, ma valve agulugufe opangidwa ndi pneumatic flanged ali ndi ntchito zosiyanasiyana: pochiza gasi m'mapaki ogulitsa mankhwala, angagwiritsidwe ntchito molumikizana ndi machitidwe owunikira pa intaneti kuti asinthe kutsegulidwa kwa valve, kuwonetsetsa kuti ndende ya VOCs emission imakhalabe yokhazikika ndikukwaniritsa miyezo. Mu chitoliro gasi kuyeretsedwa siteji ya zinyalala incineration mphamvu zomera, akhoza mwamsanga kudula mkulu-kutentha chitoliro mpweya ndimeyi ndi kuonetsetsa chitetezo cha denitration zipangizo kukonza. Mu dongosolo lotolera gasi lotolera la msonkhano wa utoto wopopera, kudzera muulamuliro wolumikizana ndi fani, kuchuluka kwa utsi kumatha kusinthidwa mwanzeru molingana ndi kamvekedwe ka kupanga, kukwaniritsa maubwino awiri achitetezo champhamvu komanso kuteteza chilengedwe. 

Mavavu a Jinbin adakhazikika pakupanga mavavu (opanga ma valve a butterfly) kwa zaka 20. Ngati muli ndi zosowa zina, chonde titumizireni pansipa ndipo mudzalandira yankho mkati mwa maola 24!
