Valavu Yoyang'anira Yapamwamba Kwambiri Yamakampani Ogulitsa ku China Wopanga fakitale
Kodi valavu yoyezera ndi chiyani?
Valvu yowunikira ndi mtundu wa valavu yogwirira ntchito mbali imodzi, komanso ngati mavalavu osabwerera.
Valavu YowunikiraNdi valavu yosavuta komanso yodalirika yokhala ndi mpira wozungulira ngati gawo lokhalo losuntha loletsa kuyenda kwa madzi m'mbuyo. Chifukwa cha kapangidwe kake kosavuta koyenda bwino komanso kosasamalira, valavuyi nthawi zambiri imatchulidwa ndipo imagwiritsidwa ntchito m'malo okwezera madzi akuda omwe amatha kulowa m'madzi. Mpando wa valavu wodzaza ndi madoko umapangidwa mwapadera kuti mpirawo ukhale wolimba popanda kulowa mu mpando wa valavu. Pakugwiritsa ntchito valavu yotulutsa mpweya kapena yoletsa kusefukira kwa madzi, mpira "woyandama" m'malo mwa "womira".
ma valve owunikiraMuli mpira womwe umakhala pampando, womwe uli ndi dzenje limodzi lokha. Umagwira ntchito pogwiritsa ntchito mpira womwe umayenda mmwamba ndi pansi mkati mwa valavu. Mpandowo umapangidwa kuti ugwirizane ndi mpirawo, ndipo chipindacho chimakhala chooneka ngati chozungulira kuti chitsogolere mpirawo kupita pampando kuti utseke ndikuletsa kuyenda kwa m'mbuyo. Mpirawo uli ndi mulifupi wokulirapo pang'ono kuposa wa dzenje lolowera (mpando). Pamene kuthamanga kwa mpando kukupitirira kuposa mpirawo, madzi amaloledwa kuyenda kudzera mu valavu. Koma kuthamanga kwa mpirawo kukupitirira kuthamanga kwa pansi pa mpandowo, mpirawo umabwerera kuti upumule pampandowo, ndikupanga chisindikizo chomwe chimaletsa kubwerera m'mbuyo. Mpirawo umasuntha mmwamba ndi pansi mkati mwa valavu kutengera kuyenda kwa madziwo ndikutseka mpando wopangidwa ndi makinawo pamene palibe kuyenda kwa madziwo kapena kuyenda kwa madziwo ndipo umatseka mpando kuti uletse kuyenda kwa madziwo.
Zinthu zazikulu za valavu yoyezera
Makhalidwe ndi ubwino waValavu Yowunikira
- kuletsa kuyenda kwa mpweya m'mbuyo,kapangidwe kopanda kukonza, koyenera malo okwerera madzi otayira omwe amatha kuyikidwa pansi pa madzi.
- *Mpando wa valavu wodzaza ndi ma ports wapangidwa mwapadera kuti mpirawo ukhale wolimba popanda kulowa mu valavu.
- *NortechValavu YowunikiraZimadziyeretsa zokha, pamene mpirawo umazungulira panthawi yogwira ntchito zomwe zimachotsa chiopsezo cha zinyalala zomwe zimamatira pa mpirawo.
- *Bore yodzaza komanso yosalala imatsimikizira kuyenda bwino komanso kutayika kwa mphamvu zochepa komanso imachotsa chiopsezo cha malo omwe pansi pake angalepheretse kutsekedwa bwino. Mpira wamba wapangidwa ndi maziko achitsulo okhala ndi rabara ya NBR, ndipo kulimba kwa rabara kumakonzedwa bwino kuti mpirawo usamatirire pampando. Mipira ya polyurethane ndi yoyenera kugwiritsidwa ntchito popanga zinthu zolimbitsa thupi komanso pamene mipira yosiyanasiyana ikufunika kuti ipewe phokoso ndi nyundo yamadzi.

Kugwiritsa ntchito ma valve owunikira
Mtundu uwu wavalavu yoyezeraimagwiritsidwa ntchito kwambiri m'mafakitale ogwiritsira ntchito madzi otayira, magetsi, ndi makampani opanga zinthu. Valavu yoyezera mpira ndi yoyenera kugwiritsidwa ntchito m'malo oipitsidwa (mpaka 120˚F) chifukwa valavu yooneka ngati mpira imaletsa kusonkhanitsa dothi. Nthawi zambiri malo onyamulira madzi otayira amakhala ndi valavu yoyezera mpira kuti isayende mobwerera m'mbuyo. Imagwiritsidwanso ntchito kwambiri m'malo opopera madzi omwe sapezeka kawirikawiri.
