Mbali ya PQ idakwera njira ziwiri zomata eccentric hemisphere valve

Mbali ya PQ yokhala ndi njira ziwiri yosindikizira eccentric hemisphere valve imapangidwa potengera mtundu wa kopanira wothamanga kwambiri kudzera mu valavu yopangidwa ndi kampani ya CANALI yaku Germany. Mapangidwe ake amatengera mfundo ya eccentric clamping, ndipo amakwaniritsa cholinga cholimbitsa ma valve, kusintha ndi kutseka kudzera munjira yotumizira. Chosindikizira ndi mphete yachitsulo yokhala ndi nkhope yolimba yosindikiza. Kapangidwe kaŵirikaŵiri kamene kali pakatikati pa valve yotseguka yomwe ili m'chipinda cha mpira, ndipo gawo loyenda ndilochepa Pamene valavu imatsegulidwa, pamwamba pa chigawo cha valve pang'onopang'ono pampando wa valve, zomwe zingathe kuchotsa bwino zopinga zochepetsera ndikukwaniritsa. kusindikiza kodalirika. Mbali yoyamba ndi yothandiza kwambiri pamayendedwe osakanikirana a magawo awiri osakanikirana osavuta kukulitsa mvula yolimba; chinthu chachiwiri ndi chakuti gawo la valavuli limakutidwa ndi ma alloys osiyanasiyana pa bimetal ndi zitsulo zoyambira, ndipo mpando wa valve umaphimbidwanso ndi aloyi yofanana. Pambuyo pa chithandizo chapadera, gulu losindikizira pamwamba limapangidwa ndi mitundu yosiyanasiyana monga anti-corrosion, kuvala kukana, mphamvu zambiri, ndi zina zotero, kukwaniritsa zosowa za nthawi zosiyanasiyana; chachitatu ndi chakuti kusindikiza ndi kolimba, ndi kayendedwe ka mpweya woipa akhoza kufika muyezo Palibe kutayikira; chinthu chachinayi ndi chakuti valavu ya valavu ya awiri osindikiza imakhala ndi malipiro. Mpando wa valve ukavala, ukhoza kusindikizidwa modalirika ndipo moyo wautumiki ukhoza kuwonjezereka mwa kutembenuka pang'ono pamene watsekedwa. Kuonjezera apo, mtedza woponderezedwa ukhoza kugwiritsidwabe ntchito pambuyo pophwanyidwa, kusinthidwa kapena kusinthidwa ndi wogwiritsa ntchito, zomwe zimapewa zolakwika za kulephera kwa ma valve ambiri omwe alipo komanso kuchotsedwa kwathunthu. Chifukwa chake, kusankha kwa mitundu yosiyanasiyana ya aloyi ya bimetallic seal kungagwiritsidwe ntchito m'mafakitale osiyanasiyana omwe amafunikira kusindikiza mwamphamvu, monga kukana kuvala, kukana dzimbiri, kukana kutentha kwambiri, etc.
