Chiyambi cha ntchito, zinthu zazikulu ndi mawonekedwe a valavu yowunikira mbale ziwiri ya wafer

Wafermbale ziwirivalavu yoyezeraAmatanthauza valavu yomwe imatsegula ndikutseka yokha chivundikiro cha valavu podalira kuyenda kwa cholumikiziracho kuti ipewe kubwerera kwa cholumikiziracho, chomwe chimadziwikanso kuti check valve, one-way valve, reverse flow valve ndi back pressure valve.mbale ziwirivalavu yoyezerandi valavu yodziyimira yokha yomwe ntchito yake yayikulu ndikuletsa kubwerera kwa cholumikizira, kuletsa kuzungulira kwa pampu ndi mota yoyendetsera, ndikutulutsa cholumikiziracho mu chidebe.mbale ziwiriMa valve oyezera angagwiritsidwenso ntchito pamizere yopereka machitidwe othandizira komwe kuthamanga kumatha kukwera pamwamba pa kuthamanga kwa dongosolo.

1. Kugwiritsa ntchito valavu yowunikira mbale ziwiri ya Wafer:

Wafermbale ziwirivalavu yoyezeraimayikidwa mu dongosolo la mapaipi, ndipo ntchito yake yayikulu ndikuletsa kuti sipabwerera m'mbuyo kwa sing'anga.mbale ziwirivalavu yoyezerandi valavu yodziyimira yokha yomwe imatsegulidwa ndi kutsekedwa kutengera mphamvu yapakati.mbale ziwirivalavu yoyezeraNdi yoyenera kugwiritsa ntchito mphamvu ya PN1.0MPa~42.0MPa, Class150~25000; m'mimba mwake DN15~1200mm, NPS1/2~48; kutentha kwa ntchito -196~540℃ pa mapaipi osiyanasiyana, omwe amagwiritsidwa ntchito poletsa kubwerera kwa njira yolumikizira magetsi. Posankha zinthu zosiyanasiyana, ingagwiritsidwe ntchito pazinthu zosiyanasiyana monga madzi, nthunzi, mafuta, nitric acid, acetic acid, strong oxidizing medium ndi uric acid.

2. Zinthu zazikulu za wafermbale ziwirivalavu yowunikira:

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 kambale ziwirivalavu yowunikira:

1. Kutalika kwa kapangidwe kake ndi kochepa, ndipo kutalika kwake ndi 1/4 ~ 1/8 yokha ya flange yachikhalidwekugwedezekavalavu yoyezera.

2. Kukula kochepa komanso kulemera kopepuka, kulemera kwake ndi 1/4 ~ 1/20 yokha ya flange yachikhalidwekugwedezekavalavu yoyezera.

3. Disiki ya valavu imatsekedwa mwachangu ndipo mphamvu ya nyundo ya madzi ndi yochepa

4. Mapaipi onse opingasa kapena oimirira angagwiritsidwe ntchito, osavuta kuyika

5. Njira yoyendetsera madzi ndi yosalala ndipo kukana kwa madzi ndi kochepa

6. Kuchita bwino komanso kugwira ntchito bwino potseka

7. Kuyenda kwa diski ya valavu ndi kochepa ndipo mphamvu yotseka ndi yochepa

8. Kapangidwe kake konse ndi kosavuta komanso kakang'ono, ndipo mawonekedwe ake ndi okongola

9. Utumiki wautali komanso magwiridwe antchito odalirika

Chachinayi, zolakwa zofala zambale ziwiriMa valve oyesera ndi awa:

1. Chimbale cha valavu chasweka

Kupanikizika kwa sing'anga isanayambe komanso itathambale ziwirivalavu yoyezeraChivundikiro cha valavu nthawi zambiri chimamenyedwa ndi mpando wa valavu, ndipo chivundikiro cha valavu chopangidwa ndi zinthu zina zofooka (monga chitsulo chosungunuka, mkuwa, ndi zina zotero) chimamenyedwa.

Njira yodzitetezera ndikugwiritsa ntchitombale ziwirivalavu yowunikira yokhala ndi diski ngati chinthu chodulira.

2. Kubwerera kwapakati

Malo otsekera awonongeka; zinyalala zatsekedwa.

Mwa kukonza pamwamba pa kutseka ndi kuyeretsa zinyalala, kubwerera kwa madzi kungapewedwe.
