Ductile Iron Soft Seal Gate Valve VS.Chipata cha Ductile Iron Hard Seal Gate
Ma valve otsekera pachipata ndi ma valve osindikizira olimba ndi zida zomwe zimagwiritsidwa ntchito kwambiri pakuwongolera ndi kutsekereza kutuluka, onse amakhala ndi ntchito yabwino yosindikiza, kugwiritsa ntchito mosiyanasiyana, ndipo ndi imodzi mwazinthu zomwe makasitomala amagula kwambiri.Ma novice ena ogula angakhale ndi chidwi, mofanana ndi valavu yachipata, kodi pali kusiyana kotani pakati pawo?
Chisindikizo chofewa ndi chisindikizo pakati pa zitsulo ndi zopanda zitsulo, pamene chisindikizo cholimba ndi chisindikizo pakati pa zitsulo ndi zitsulo.Valavu yofewa yosindikizira pachipata ndi valavu yosindikizira pachipata ndi zida zosindikizira, chisindikizo cholimba chimapangidwa bwino ndi zida zapampando kuti zitsimikizire kulondola kwa spool (mpira), nthawi zambiri chitsulo chosapanga dzimbiri ndi mkuwa.Chisindikizo chofewa chimayikidwa muzitsulo zosindikizira mpando wa valve ndi zinthu zopanda zitsulo, chifukwa cha zinthu zofewa zosindikizira zimakhala ndi mlingo winawake wa elasticity, motero zofunikira zoyendetsera bwino ndizochepa kusiyana ndi chisindikizo cholimba.Pansipa ndikukutengerani kuti mumvetsetse kusiyana pakati pa valve yotsekera pachipata ndi valavu yosindikizira yolimba.
Zida zosindikizira zoyamba
1. Zida ziwiri zosindikizira ndizosiyana.Vavu yotsekera pachipata nthawi zambiri imakhala mphira kapena PTFE ndi zida zina.Vavu yosindikiza pachipata cholimba pogwiritsa ntchito chitsulo chosapanga dzimbiri ndi zitsulo zina.
2. Chisindikizo chofewa: kusindikiza mbali yotsatila ya mbali ziwiri zachitsulo, mbali inayo ya zotanuka zopanda zitsulo, zomwe zimatchedwa "soft seal".The kusindikiza zotsatira za mavavu amenewa pachipata, koma osati mkulu kutentha, zosavuta kuvala ndi kung'amba, ndi osauka makina katundu.Monga chitsulo + mphira;zitsulo + PTFE ndi zina zotero.
3. Chisindikizo cholimba: kusindikiza mwamphamvu ndi kusindikiza mbali zonse ndi zitsulo kapena zipangizo zina zolimba.Kusindikiza kwa valve pachipata koteroko ndi koyipa, koma kukana kutentha kwambiri, kukana kuvala, ndi zinthu zabwino zamakina.Monga chitsulo + chitsulo;chitsulo + mkuwa;chitsulo + graphite;chitsulo + aloyi chitsulo;(atha kugwiritsanso ntchito chitsulo choponyedwa, chitsulo cha aloyi, aloyi wa utoto wopopera, etc.).
Chachiwiri, ntchito yomanga
Makampani opanga makina ali ndi malo ogwirira ntchito ovuta, ambiri omwe ndi otentha kwambiri komanso otsika kwambiri, kukana kwapa media, komanso kuwononga.Tsopano, kupita patsogolo kwaukadaulo kwadzetsa kutchuka kwa ma valve osindikizira a zipata zolimba.
Poganizira za mgwirizano pakati pa kulimba kwachitsulo, valavu yosindikizira pachipata cholimba, ndi kusindikiza kofewa, thupi la valve liyenera kuumitsidwa, ndi mbale ya valve ndi mpando wa valve kuti apitirize kupera kuti asindikize.Kuzungulira kwa valve yosindikizira pachipata ndi nthawi yayitali.
Chachitatu, kugwiritsa ntchito zikhalidwe
1, chisindikizo chofewa chimatha kuzindikira kutayikira kwa zero, chisindikizo cholimba chimatha kusinthidwa malinga ndi zofunikira zapamwamba ndi zotsika;
2, Zisindikizo zofewa zimatha kutayikira kutentha kwambiri, zimayenera kulabadira kupewa moto, ndipo zisindikizo zolimba sizingadutse kutentha kwambiri.Chisindikizo cholimba cha valve chotseka chadzidzidzi chingagwiritsidwe ntchito pazovuta kwambiri, chisindikizo chofewa sichingagwiritsidwe ntchito.
3, kwa media zina zowononga, chisindikizo chofewa sichingagwiritsidwe ntchito, mutha kugwiritsa ntchito chisindikizo cholimba;
4, pakutentha kwambiri, zosindikizira zofewa zimakhala ndi kutayikira, chisindikizo cholimba sivuto;
Chachinayi, kusankha zida
Magawo onse osindikizira amatha kufika asanu ndi limodzi, nthawi zambiri kutengera njira yapakati, kutentha, ndi kukakamizidwa kuti asankhe valve yoyenera yachipata.Kwa media wamba omwe ali ndi tinthu tating'onoting'ono kapena abrasive, kapena kutentha kupitilira madigiri 200, ndikwabwino kusankha chisindikizo cholimba.Ngati torque ya valve yotseka ndi yayikulu, muyenera kusankha kugwiritsa ntchito valavu yosindikizira yolimba.
Chachisanu, kusiyana kwa moyo wautumiki
Ubwino wa chisindikizo chofewa ndikusindikiza bwino, choyipa chake ndikuti ndi kosavuta kukalamba, kuvala ndikung'amba, moyo waufupi.Moyo wautumiki wosindikiza mwamphamvu ndi wautali, ndipo kusindikiza kumakhala koyipa kuposa kusindikiza kofewa, ziwirizi zimatha kuthandizirana.
Zomwe zili pamwambazi ndizosiyana pakati pa valve yofewa yosindikizira pachipata ndi kugawana chidziwitso cha chidziwitso cha valve, ndikuyembekeza kuti nditha kukuthandizani pa ntchito yogula zinthu.
