Ma valve oyezera waferAmadziwikanso kuti ma valve obwerera m'mbuyo, ma valve obwerera m'mbuyo, ndi ma valve obwerera m'mbuyo. Ma valve amtunduwu amatsegulidwa ndi kutsekedwa okha ndi mphamvu yopangidwa ndi kuyenda kwa chinthucho chomwe chili mupaipi, chomwe ndi cha mtundu wa valavu yodziyimira yokha.
Valavu yowunikira imadalira kuyenda kwa cholumikiziracho ndipo imatsegula ndikutseka cholumikizira cha valavu yokha, chomwe chimagwiritsidwa ntchito poletsa valavu yowunikira yapakati, yomwe imadziwikanso kuti valavu yowunikira, valavu yowunikira, valavu yowunikira ya kumbuyo, ndi valavu yowunikira ya kumbuyo. Valavu yowunikira ndi ya mtundu wa valavu yodziwikiratu, ntchito yake yayikulu ndikuletsa kubwerera kwa media, kuletsa kutembenuka kwa pampu ndi galimoto, komanso kutulutsa kwa media yoyendetsera chidebe. Mavavu owunikira angagwiritsidwenso ntchito kupatsa mphamvu kuti ikwezeke mpaka kupitirira kuthamanga kwa system ya system yothandizira kuti ipereke payipi yoperekera. Valavu yowunikira ikhoza kugawidwa kukhala valavu yowunikira ya swing (malinga ndi pakati pa kuzungulira kwa mphamvu yokoka) ndi valavu yowunikira yokweza (yoyenda motsatira mzere).
Choyamba, kugwiritsa ntchito valavu yowunikira yowunikira yoyikidwa mu dongosolo la mapaipi, ntchito yake yayikulu ndikuletsa kubwerera kwa media, valavu yowunikira ndi mtundu wa valavu yodziyimira yokha yomwe imadalira kuthamanga kwa media kuti itsegule ndi kutseka. Valavu yowunikira yolumikizira ndi yoyenera kuthamanga kwa nominal PN1.0MPa ~ 42.0MPa, Class150 ~ 25000, m'mimba mwake DN15 ~ 1200mm, NPS1/2 ~ 48, kutentha kwa ntchito -196 ~ 540 ℃ kwa mapaipi osiyanasiyana, omwe amagwiritsidwa ntchito poletsa kubwerera kwa media. Kudzera mu kusankha kwa zipangizo zosiyanasiyana, ingagwiritsidwe ntchito pamadzi, nthunzi, mafuta, nitric acid, acetic acid, oxidizing media yamphamvu ndi uric acid ndi zina.
Zipangizo zazikulu za valavu yoyezera wafer ndi chitsulo cha carbon, chitsulo chotentha pang'ono, chitsulo cha duplex (SS2205/SS2507), titanium alloy, aluminiyamu bronze, Inconel, SS304, SS304L, SS316, SS316L, chrome-molybdenum steel, Monel (400/500), 20# alloy, Hastelloy ndi zipangizo zina zachitsulo.
Chachitatu, miyezo ndi malamulo a valavu yowunikira ya wafer
Kapangidwe: API594, API6D, JB/T89372,
Utali wa nkhope ndi nkhope：API594、API6D、DIN3202、JB/T89373、
Kuthamanga ndi kutentha kwa kuthamanga kwa magazi：ANSI B16.34、DIN2401、GB/T9124、HG20604、HG20625、SH3406、JB/T744、
Muyezo woyesera ndi kuwunika: API598, JB/T90925
Mapaipi a Piping：JB/T74~90、GB/T9112-9124、HG20592~20635、SH3406、ANSI B 16.5、DIN2543-2548、GB/T13402、API605、ASMEB16.47
Chachinayi, makhalidwe a kapangidwe ka valavu yowunikira pinch
1. Kutalika kwa kapangidwe kake kochepa, kutalika kwa kapangidwe kake ndi 1/4 ~ 1/8 yokha ya valavu yoyang'anira flange yachikhalidwe.
2. voliyumu yaying'ono, kulemera kopepuka, kulemera kwake ndi valavu yowunikira ya flange yachikhalidwe yokha 1/4 ~ 1/2
3. Chophimba cha valavu chimatseka mwachangu, kuthamanga kwa nyundo ya madzi kumakhala kochepa
4. Mapaipi opingasa kapena oimirira angagwiritsidwe ntchito, osavuta kuyika
5. Njira yoyenda bwino, yolimba pang'ono
6. Kuchitapo kanthu koyenera, kugwira ntchito bwino kosindikiza
7. Kugunda kwa disc ndi kochepa, kutseka kwake kumakhala kochepa
8. Kapangidwe kake konse ndi kosavuta komanso kakang'ono, ndipo mawonekedwe ake ndi okongola
9. Utumiki wautali komanso magwiridwe antchito odalirika
zisanu. Kutsekeka kwa valavu yoyezera wafer. Vavu yoyezera wafer yotsekedwa bwino imatha kubweretsa kutayikira konse, koma valavu yoyezera wafer yotsekedwa bwino si valavu yotayikira konse. Ili ndi kuchuluka kwa kutayikira. Malinga ndi muyezo wowunikira wa API598, pa valavu yoyezera yokhala ndi mpando wachitsulo, kukula kwa DN100, kuchuluka kwa kutayikira kwa madzi pamphindi ndi 12CC.
