–, wafavalavu yoyezeragwiritsani ntchito:
Valavu yowunikira yomwe yayikidwa mu dongosolo la mapaipi, ntchito yayikulu ndikuletsa kuti media ibwerere m'mbuyo, valavu yowunikira ndi mtundu wa media pressure yomwe imatsegulidwa ndikutsekedwa yokha. Valavu yowunikira ya Wafer ndi yoyenera kuthamanga kwa nominal PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; Nominal diameter DN15 ~ 1200mm, NPS1/2 ~ 48; Kutentha kwa ntchito -196 ~ 540°C kwa mitundu yonse ya mapaipi, komwe kumagwiritsidwa ntchito poletsa media backflow. Kudzera mu kusankha kwa zipangizo zosiyanasiyana, ingagwiritsidwe ntchito m'madzi, nthunzi, mafuta, nitric acid, acetic acid, strong oxidizing medium ndi uric acid ndi zina zotero.
Awiri, mfundo zazikulu za valavu yoyezera ya wafer:
Pali chitsulo cha carbon, chitsulo chotentha pang'ono, chitsulo cha magawo awiri F51/F55, titanium alloy, aluminiyamu bronze, INCONEL, SS304, SS304L, SS316, SS316L, chromium-molybdenum steel, Nair 400/500, 20# alloy, Hastelloy alloy ndi zipangizo zina zachitsulo. Kagwiritsidwe ntchito ndi kapangidwe kake ka wafer check valve.
Zitatu, wafervalavu yoyezeramiyezo ndi zofunikira:
1, kapangidwe ndi kupanga: API594, API6D,JB/ T8937,JB/T3595,
2, Kutalika kwa kapangidwe: API594, API6D, DIN3202, JB/T8937, ANSI/ASME B16.10
3, Kutulutsa, kutentha kwapakati: ANSI B16.34, DIN2401, GB/T9124, HG20604, HG20625, SH3406, JB/T74
4, mayeso ndi kuwunika: API598, JB/T9092, GB/T13927
5, chitoliro cha mapaipi: JB/ T74-90, GB/T9112-9124, HG20592-20635, SH3406, ANSI/ASME B 16.5, DIN2543-2548.
GB/T13402, API605, ASMEB17
Chachinayi, makhalidwe a valavu yowunikira cholumikizira:
1, kutalika kwa kapangidwe kake ndi kochepa, kutalika kwa kapangidwe kake ndi 1/4 ~ 1/8 yokha ya valavu yowunikira ya flange yachikhalidwe
2, kukula kochepa, kulemera kopepuka, kulemera kwake ndi 1/4 ~ 1/20 yokha ya valavu yoyang'anira flange yachikhalidwe
3, diski imatseka mwachangu, kuthamanga kwa nyundo yamadzi ndi kochepa
4, payipi yopingasa kapena payipi yoyimirira ingagwiritsidwe ntchito, yosavuta kuyiyika
5, njira yoyenda bwino, kukana madzi pang'ono
6, ntchito yodziwikiratu, magwiridwe antchito abwino osindikiza
7, kugunda kwa disc ndi kochepa, kutseka kwake ndi kochepa
8, kapangidwe kake konsekonse ndi kosavuta komanso kakang'ono, kokongola
9, moyo wautali wautumiki, magwiridwe antchito odalirika
Ntchito ya valavu yowunikira mu dongosolo loperekera madzi pa pampu ndikuletsa kugwedezeka kwa madzi othamanga kwambiri pa impeller ya pampu. Chifukwa cha zifukwa zina pakugwira ntchito kwa dongosololi, pamene pampu yasiya kugwira ntchito mwadzidzidzi, kuthamanga kwa madzi mu pampu kumatha, ndipo madzi othamanga kwambiri olumikizidwa ndi chotulutsira pampu amabwerera ku pampu. Pamene chotulutsira pampu chili ndi valavu yowunikira, imatseka nthawi yomweyo kuti madzi othamanga kwambiri asabwerere ku pampu. Mavalavu owunikira amagwiritsidwa ntchito mu machitidwe a madzi otentha kuti aletse madzi otentha kubwerera m'mapaipi. Mapaipi a PVC amatha kuwononga mapaipi ndikuvulaza anthu, makamaka mu machitidwe otenthetsera madzi a dzuwa.
Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
