Dzina lovomerezeka la blind plate ndiflangekapu, ena amatchedwanso blind flange kapena pulagi ya chitoliro. Ndi aflangepopanda dzenje pakati, ntchito kusindikiza pakamwa chitoliro. NTCHITO YOMWEYO NDI YOMWEYO NDI mutu ndi kapu ya chubu, kupatula kuti chisindikizo chakhungu ndi chipangizo chosindikizira cha deTAChable, ndipo chisindikizo chamutu sichili chokonzeka kutsegulidwa kachiwiri. Pali mitundu yambiri yosindikizira pamwamba, kuphatikizapo ndege, pamwamba pa convex, concave ndi convex pamwamba, tenon pamwamba ndi mphete yolumikiza pamwamba. Zida: carbon zitsulo, chitsulo chosapanga dzimbiri, aloyi zitsulo, mkuwa, zotayidwa, PVC ndi PPR.
Chovala chakhungu chimagwiritsidwa ntchito makamaka pakudzipatula kwathunthu kwa sing'anga yopangira kuti aletse kupanga kuti asakhudzidwe ndi kutsekeka kwa valve yodulidwa komanso kuchititsa ngozi. Chovala chakhungu chiyenera kukhazikitsidwa m'zigawo zomwe zimafuna kudzipatula, monga mphuno ya zida, isanayambe kapena itatha valavu yodulidwa kapena pakati pa ma flanges awiri. Chithunzi 8 mbale yakhungu nthawi zambiri imalimbikitsidwa. Pa kukanikiza, kutsuka ndi zina zogwiritsa ntchito kamodzi kokha zitha kugwiritsa ntchito pulagi mbale (zozungulira akhungu mbale).

1. Pa gawo loyambirira lokonzekera, kuyesa mphamvu kapena kulimba kwa payipi sikungachitike nthawi imodzi ndi zida zolumikizidwa (monga turbine, compressor, gasifier, reactor, etc.), ndi akhungu. mbale ayenera kukhazikitsidwa pa kugwirizana pakati pa zipangizo ndi payipi.
2. Pamitundu yonse yamapaipi azinthu zolumikizidwa kudera lamalire kunja kwa malire, chipangizocho chikayima, ngati payipi ikugwirabe ntchito, ikani mbale yakhungu pa valve yodulidwa.
3. Ngati chipangizocho chili ndi mndandanda wambiri, chitoliro chachikulu chochokera kunja kwa dera la malire chimagawidwa mu zikwi zikwi za njira za chitoliro mu mndandanda uliwonse, ndipo valavu ya cutoff ya njira iliyonse ya chitoliro imayikidwa ndi mbale yomaliza.
4. Pamene chipangizochi chikufunikira kukonzanso nthawi zonse, kuyang'anitsitsa kapena kusinthana, zipangizo zomwe zimakhudzidwa ziyenera kukhala zodzipatula, ndipo mbale yakhungu imayikidwa pa valve yodulidwa.
5. Pamene payipi yochapira ndi kukakamiza ndi mapaipi a gasi olowa m'malo (monga mapaipi a nayitrogeni ndi mapaipi a mpweya) alumikizidwa ndi zida, mbale yakhungu iyenera kuyikidwa pa valve yodulira.
6. Yeretsani malo otsika a zida ndi mapaipi. Ngati ndondomekoyi iyenera kukhala pakati pa ndondomeko yosonkhanitsa pamodzi, ikani mbale yakhungu pambuyo pa valavu yodulidwa.
7. Mbale zakhungu kapena mapulagi amawaya aziikidwa kumbuyo kwa mavavu a mapaipi otulutsa mpweya, mapaipi otulutsa madzi ndi mipope ya zitsanzo za zida ndi mapaipi. Zinthu zopanda poizoni, zosawononga thanzi komanso zosaphulika sizimachotsedwa.
8. Pamene kukhazikitsidwa kumamangidwa ndi masitepe, mbale yakhungu iyenera kukhazikitsidwa pa valve yodulidwa ya mapaipi ogwirizana wina ndi mzake, kuti athandize kumanga kotsatira.
9. Chidacho chikapangidwa mwachizolowezi, mapaipi ena othandizira omwe amafunika kudulidwa kwathunthu ayeneranso kukhala ndi mbale zakhungu. ? [1]?
Zinthu zofunika kuziganizira
1. Pamalo okwaniritsa zofunikira za ndondomekoyi, ikani mbale zochepa zakhungu momwe mungathere.
2. Chovala chakhungu chokhazikitsidwa chiyenera kusonyeza kutseguka kwabwino kapena kutseka koyenera.
3. Gawo la mbale yakhungu yomwe imayikidwa mu valve yodulidwa, kumtunda kapena kumtunda, iyenera kutsimikiziridwa molingana ndi zotsatira zodulidwa, chitetezo ndi ndondomeko.
