Lero tikupitiriza kulankhula za njira zodzitetezera ku ma valve:
Tabu 7
Pamene kuwotcherera chitoliro, pakamwa molakwika pambuyo chitoliro si pa mzere pakati, palibe kusiyana mu awiriwo, wandiweyani khoma chitoliro si fosholo poyambira, ndi m'lifupi ndi kutalika kwa weld si kukumana zofunika za malamulo yomanga. .
Zotsatira: chitoliro molakwika kubwereketsa si mu mzere wapakati mwachindunji zimakhudza kuwotcherera khalidwe ndi maganizo khalidwe. Palibe kusiyana mu awiriwo, wandiweyani khoma chitoliro si fosholo poyambira, m'lifupi ndi kutalika kwa weld si kukumana ndi zofunikira za kuwotcherera sangathe kukwaniritsa zofunika mphamvu.
Miyeso: mutatha kuwotcherera chitoliro, chitolirocho sichiyenera kugwedezeka pamzere wapakati; mpata uyenera kusiyidwa; chitoliro chokhuthala cha khoma chiyenera kufosholo. Komanso, m'lifupi ndi kutalika kwa weld adzakhala welded malinga ndi zofunikira.
Tabu 8
Chitolirocho chimakwiriridwa mwachindunji m'nthaka yachisanu ndi nthaka yosasamalidwa bwino, ndipo katayanidwe kake ndi malo a piers zothandizira mapaipi ndizosayenera, ndipo ngakhale ngati njerwa zouma pabwalo.
Zotsatira zake: Chifukwa cha kuthandizira kosakhazikika, payipiyo inawonongeka panthawi ya kubwezeretsanso, zomwe zinayambitsa kukonzanso ndi kukonzanso.
Miyezo: payipi sayenera kukwiriridwa m'nthaka yowuma komanso dothi lotayirira, malo otsetsereka amayenera kukwaniritsa zofunikira pakumanga, chothandizira chiyenera kukhala cholimba, makamaka mawonekedwe a mapaipi, sayenera kukhala ndi mphamvu yakumeta ubweya. Zipinda zothandizira njerwa ziyenera kumangidwa ndi madzi ndi mchenga kuti zitsimikizire kukhulupirika ndi kulimba.
Tabu 9
Bawuti yokulirapo ya zinthu zothandizira chitoliro chokhazikika ndi yotsika, kabowo ka bawuti yokulirapo ndi yayikulu kwambiri kapena bawuti yowonjezera imayikidwa pakhoma la njerwa kapena ngakhale khoma lowala.
Zotsatira zake: Thandizo la chitoliro ndi lotayirira, kupindika kwa chitoliro, kapena kugwa.
Miyezo: mabawuti okulitsa ayenera kusankha zinthu zoyenerera, ngati kuli kofunikira, ziyenera kutsatiridwa kuti ziwunikidwe, kabowo kokhazikitsa mabawuti okulirapo sayenera kukhala wamkulu kuposa 2mm m'mimba mwake ya ma bawuti okukula, mabawuti okulitsa amayenera kugwiritsidwa ntchito pamapangidwe a konkire.
Taboo 10
Flange mbale ndi liner sizolimba mokwanira, ndipo mabawuti olumikizira ndi aafupi kapena owonda m'mimba mwake. Chitoliro cha mphira chimagwiritsidwa ntchito ngati chitoliro chotenthetsera, mphira iwiri kapena chopendekera cha chitoliro chamadzi ozizira, ndi liner ya flange yotulukira mu chubu.
Zotsatira: kugwirizana kwa mbale ya flange sikolimba, kapena kuwonongeka, kutayikira. Kuyika kwa flange mu chubu kumawonjezera kukana koyenda.
Miyeso: Chitoliro cha flange mbale ndi liner ziyenera kukwaniritsa zofunikira za chitoliro chogwirira ntchito.
Mapaipi a asbestos opangira mphira otenthetsera ndi mapaipi operekera madzi otentha ndi mapaipi amphira operekera madzi ndi mipope yokhetsa madzi.
Flange liner sayenera kulowa mu chubu, bwalo lake lakunja kwa bowo la flange ndiloyenera. Pakatikati pa flange palibe pad kapena zomangira zingapo. M'mimba mwake wa bawuti wolumikiza flange uyenera kukhala wochepera 2mm kuposa momwe amabowola mbale ya flange, ndipo kutalika kwa bawuti ndodo yotuluka kuyenera kukhala 1/2 ya makulidwe a mtedza.
Taboo 11
Mafotokozedwe ndi zitsanzo za valve yoyikidwa sizikugwirizana ndi zofunikira za mapangidwe.
Mwachitsanzo, kuthamanga kwadzina kwa valve kumakhala kochepa kusiyana ndi kuyesa kwa dongosolo; valavu pachipata cha chakudya madzi nthambi chitoliro pamene chitoliro awiri ndi zosakwana kapena wofanana 50mm; zowuma ndi risers kwa Kutenthetsa madzi otentha; ndipo chitoliro choyamwa pampu yamoto chimatenga valavu ya butterfly.
Zotsatira: zimakhudza kutsegula ndi kutseka kwabwino kwa valve ndikusintha kukana, kupanikizika ndi ntchito zina. Ngakhale kuyambitsa ntchito ya dongosolo, kuwonongeka kwa valve kumakakamizika kukonzanso.
Miyezo: Dziwani bwino kuchuluka kwa mavavu osiyanasiyana, ndipo sankhani mawonekedwe ndi mitundu ya mavavu molingana ndi kapangidwe kake. Kuthamanga mwadzina kwa valve kudzakwaniritsa zofunikira za kupanikizika kwa dongosolo la kuyesa. Malinga ndi malamulo omanga: valve yoyimitsa idzagwiritsidwa ntchito pamene chitoliro cha chitoliro ndi chocheperapo kapena chofanana ndi 50mm; valavu ya chipata iyenera kugwiritsidwa ntchito pamene m'mimba mwake wa chitoliro ndi wamkulu kuposa 50mm. Kutentha kwamadzi otentha kouma, valavu yowongolera iyenera kugwiritsidwa ntchito valavu yachipata, chitoliro choyamwa chamadzi amoto sichiyenera kugwiritsidwa ntchitovalavu ya butterfly.
Kupatula apo, Tianjin Tanggu Water Seal Valve Co., Ltd.valavu ya butterfly yachiwiri ya flange, valavu yagulugufe yapawiri ya flange eccentric, valve balance,valavu yowunikira mbale ziwiri, Y-Strainer ndi zina zotero. Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
