Nthawi zambiri ndimakumana ndi mafunso amakasitomala monga pansipa: "Moni, Beria, ndikufuna valavu yachipata, mungatitchule?"Ma valve a zipata ndi katundu wathu, ndipo timawadziwa bwino.Ndemanga palibe vuto, koma ndingamupatse bwanji mawu otengera funsoli?Kodi kutchula mawu kungathandize bwanji makasitomala kupeza maoda, kapena kugula zinthu zomwe makasitomala amafunikira?Mwachionekere, deta yokha si yokwanira.Panthawiyi, nthawi zambiri ndimafunsa kasitomala "ndi valve yamtundu wanji yomwe mukufunikira, kupanikizika ndi chiyani, kukula kwake, muli ndi sing'anga ndi kutentha?"Makasitomala ena adzakhumudwa kwambiri, ndikungofuna mtengo, mumandifunsa mafunso ambiri, ndinu osachita bwino bwanji.Ena sanafunse mafunso, ndipo anangondipatsa mawu obwereza.Koma, kodi n'zoona kuti ndife opanda ntchito?M'malo mwake, ndichifukwa choti ndife akatswiri ndipo tili ndi udindo kwa inu kuti tikufunseni mafunsowa.Inde, ndizosavuta kutchula, koma sikophweka kuthandiza makasitomala kupeza maoda.Tsopano, tiyeni tipende mfundo zomwe zikuyenera kutsatiridwa pakufunsa ndi mawu a mavavu a zipata kuchokera kuzinthu zotsatirazi.
Nthawi zambiri, zigawo za ma valve a pachipata zimaphatikizapo mawonekedwe (ndodo yotseguka kapena ndodo yakuda), kupanikizika, m'mimba mwake, zinthu, ndi kulemera.M'nkhaniyi, timangokambirana za ma valve a zipata zofewa zofewa.
1. Fomu: Pali mitundu iwiri ya ma valve otsekedwa otsekedwa, valavu yachipata chokwera ndi valavu yobisika.Valavu yachipata chokwera imafunikira malo ogwirira ntchito ochulukirapo ndipo ndiyoyeneranso ntchito zamapaipi pansi.Tsinde la valve sikuyenda mmwamba ndi pansi, choncho ndiloyenera ntchito zamapaipi apansi panthaka.
2. Kupanikizika: Kwa ma valve otsekedwa ndi zipata zofewa, kupanikizika komwe kumagwiritsidwa ntchito ndi PN10-PN16, Class150.Ziribe kanthu kuti kupanikizika kuli kotani, mbale yophimba mphira idzakhala yopunduka.Sitimalimbikitsa kugwiritsa ntchito ma valve otsekedwa ndi zipata zofewa;
3. Kukula: Izi ndizosavuta, kukula kwake kumakhala kokwera mtengo kwambiri;
4. Zofunika: Pankhani ya zinthu, ndi tsatanetsatane.Nthawi zambiri timalankhula za zinthu kuchokera kuzinthu zotsatirazi, thupi la valve, mbale ya valve, shaft;kwa mavavu otsekedwa ndi zipata zofewa, zida zomwe zimagwiritsidwa ntchito kwambiri ndi ma ductile iron body.Vavu mbale ndi ductile iron-clad rabara mbale.Pali zosankha zambiri za shaft ya valve, shaft yachitsulo ya kaboni, shaft 2cr13, shaft yachitsulo chosapanga dzimbiri, ndi gland ya valve pachipata ndi yosiyana ndi gland yachitsulo ndi mkuwa.Kwa media zowononga, nthawi zambiri Ndi bwino kugwiritsa ntchito mtedza wamkuwa ndi zopangitsa zamkuwa, zomwe sizikhala ndi zowononga zowononga, ndipo mtedza wachitsulo ndi zitsulo zamkuwa ndizokwanira.
5. Kulemera kwake: Kulemera apa kumatanthauza kulemera kwa valve imodzi, yomwe imakhalanso chinthu chomwe chimanyalanyazidwa mosavuta.Kodi zinthuzo zatsimikiziridwa, ndipo mtengo wake umatsimikiziridwa ndi valve yachipata ya kukula kwake?yankho ndi loipa.Pofuna kukwaniritsa zofuna zosiyanasiyana za msika, opanga ma valve amapanga makulidwe a ma valve kukhala osiyana, zomwe zimapangitsa kuti ngakhale zinthuzo zikhale zofanana, kukula kwake kuli kofanana, kutalika kwake kumakhala kofanana, kutalika kwa kunja kwa flange ndi mtunda wapakati wa dzenje la flange ndi wofanana, koma Kuchuluka kwa thupi la valve sikufanana, ndipo kulemera kwa valve yachipata cha kukula komweko kudzasiyananso kwambiri.Mwachitsanzo, DN100 yemweyo, DIN F4 tsinde lakuda valavu yofewa yosindikizira, tili ndi mitundu 6 ya kulemera, 10.5kg, 12kg, 14kg, 17kg, 19kg, 21kg, mwachiwonekere, kulemera kwake kumakhala kokwera mtengo kwambiri.Monga katswiri wogula, muyenera kudziwa mtundu wa ntchito yomwe mukufuna kuti igwiritsidwe ntchito, mtundu wanji womwe kasitomala amafunikira, ndi mtengo wanji womwe kasitomala amavomereza.Kwa fakitale yathu, timafuna kuti makasitomala agule zinthu zapamwamba kwambiri, kuti zogulitsa pambuyo pake zikhale zochepa.Komabe, chifukwa cha kufunikira kwa msika, tiyenera kusintha malonda athu kuti tipeze msika wambiri.
Kupyolera mu kusanthula kwazomwe zili pamwambazi, ndikukhulupirira kuti muyenera kumvetsetsa bwino kugula ma valve otsekedwa ndi zipata zofewa.Ngati mudakali ndi mafunso okhudza kugula mavavu a zipata, chonde lemberani Zhongfa Valve, ndipo tidzayesetsa kukuthandizani kuthetsa mavutowo.
