Chiyambi cha kagwiritsidwe ntchito, zinthu zazikulu ndi mawonekedwe a valavu yoyang'anira wafer

Valavu yowunikira limatanthauza valavu yomwe imatsegula ndikutseka yokha chivundikiro cha valavu podalira kuyenda kwa cholumikizira chokha kuti ipewe kubwerera kwa cholumikizira, chomwe chimadziwikanso kutivalavu yoyezera, valavu yolowera mbali imodzi, valavu yolowera mbali ina ndi valavu yokankhira kumbuyo.valavu yoyezerandi valavu yodziyimira yokha yomwe ntchito yake yayikulu ndikuletsa kubwerera kwa sing'anga, kuzungulira kwa pampu ndi mota yoyendetsera, komanso kutulutsa sing'anga mu chidebe. Mavalavu owunikira angagwiritsidwenso ntchito pamizere yopereka makina othandizira komwe kuthamanga kumatha kukwera pamwamba pa kuthamanga kwa makina.

1.TKugwiritsa ntchito valavu yoyezera wafer:

Thevalavu yoyezera imayikidwa mu dongosolo la mapaipi, ndipo ntchito yake yayikulu ndikuletsa kubwerera kwa njira yolumikizirana.valavu yoyezerandi valavu yodziyimira yokha yomwe imatsegulidwa ndi kutsekedwa kutengera kuthamanga kwapakati.Valavu yoyezera wafer Ndi yoyenera kugwiritsa ntchito mphamvu ya PN1.0MPa~42.0MPa, Class150~25000; m'mimba mwake DN15~1200mm, NPS1/2~48; Kubwerera kwapakati. Posankha zinthu zosiyanasiyana, ingagwiritsidwe ntchito pazinthu zosiyanasiyana monga madzi, nthunzi, mafuta, nitric acid, acetic acid, strong oxidizing medium ndi uric acid.

2.Tmfundo zazikulu zavalavu yoyezera wafer:

Pali chitsulo cha carbon, chitsulo chotentha pang'ono, chitsulo cha magawo awiri (F51/F55), titanium alloy, aluminiyamu bronze, INCONEL, SS304, SS304L, SS316, SS316L, chrome molybdenum steel, Monel (400/500), 20# alloy, Hastelloy ndi zipangizo zina zachitsulo.

3. Makhalidwe a kapangidwe kavalavu yoyezera wafer:

AKutalika kwa kapangidwe kake ndi kochepa, ndipo kutalika kwake ndi 1/4 ~ 1/8 yokha ya valavu yoyang'anira flange yachikhalidwe

BKukula kwake kochepa komanso kopepuka, kulemera kwake ndi 1/4 ~ 1/20 yokha ya valavu yoyang'anira flange yachikhalidwe

CDisiki ya valavu imatsekedwa mwachangu ndipo mphamvu ya nyundo ya madzi ndi yochepa

DMapaipi onse opingasa kapena oimirira angagwiritsidwe ntchito, zosavuta kuyika

ENjira yoyendera madzi ndi yosalala ndipo kukana kwa madzi ndi kochepa

FKuchita bwino komanso kugwira ntchito bwino potseka

GKuyenda kwa diski ya valavu ndi kochepa ndipo mphamvu yotseka ndi yochepa

HKapangidwe kake konse ndi kosavuta komanso kakang'ono, ndipo mawonekedwe ake ndi okongola

IMoyo wautali wautumiki komanso magwiridwe antchito odalirika

4.TZolakwika zodziwika bwino za valavu yoyezera ndi izi:

ADisiki ya valavu yasweka

Kupanikizika kwa cholumikizira magetsi chisanayambe komanso chitatha valavu yoyezera kumakhala pafupi ndi "kuwomba" ndipo nthawi zambiri kumakhala kofanana. Chida cha valavu chimamenyedwa ndi mpando wa valavu, ndipo chida cha valavu chopangidwa ndi zinthu zina zosweka (monga chitsulo chosungunuka, mkuwa, ndi zina zotero) chimasweka. Njira yopewera vutoli ndikugwiritsa ntchito valavu yoyezera yokhala ndi diski ngati chinthu chodulira.

BKubwerera kwapakati

Malo otsekera awonongeka; zinyalala zatsekeredwa. Mwa kukonza malo otsekera ndi kuyeretsa zinyalala, kuyenda kwa madzi m'malo otsekeredwa kungapeweke.
