1. Low madzimadzi kukana.
2. Mphamvu yakunja yofunikira pakutsegula ndi kutseka ndi yaying'ono.
3. Kuyenda kwa sing'anga sikumangika.
4. Mukatsegula kwathunthu, kukokoloka kwa malo osindikizira ndi sing'anga yogwira ntchito kumakhala kochepa kuposa kwa valve yoyimitsa.
5. Kufanizira mawonekedwe ndi kosavuta, ndipo teknoloji yoponyera ndi yabwino.
Zoyipa za valve yachipata
1. Miyeso yonse ndi kutalika kwa kutsegula ndi zazikulu.Zida zimafuna malo akuluakulu.
2. Potsegula ndi kutseka, pali mkangano wapakati pakati pa malo osindikizira, omwe amachititsa mwachidule kukanda.
3. Ma valve a zipata nthawi zambiri amakhala ndi malo awiri osindikizira, omwe amawonjezera zovuta zina pokonza, kugaya ndi kukonza.
Mitundu ya mavavu a zipata
1. Ikhoza kugawidwa molingana ndi dongosolo la nkhosa yamphongo
1) Valve yachipata chofanana: malo osindikizira amafanana ndi mzere woyimirira, ndiye kuti, malo awiri osindikizira amafanana.
Pakati pa ma valve a zipata zofananira, kukonzekera ndi thrust wedge ndikofala kwambiri.Pansi pa ma valve awiri a zipata pali mbali ziwiri.Mtundu uwu wa valavu yachipata ndi yoyenera kwa ma valve otsika otsika komanso ang'onoang'ono (dn40-300mm).Palinso akasupe pakati pa nkhosa zamphongo ziwirizo, zomwe zimatha kumangitsa, zomwe zimathandiza kuti nkhosayo idindwe chidindo.
2) Valovu yachipata cha Wedge: malo osindikizira amapanga ngodya yokhala ndi mzere woyimirira, ndiye kuti, malo awiri osindikizira amapanga valve yooneka ngati mphero.The ankakonda ngodya ya kusindikiza pamwamba nthawi zambiri 2 ° 52 ', 3 ° 30′, 5 °, 8 °, 10 °, etc. kukula kwa ngodya makamaka zimadalira concave otukukirani a sing'anga kutentha.Nthawi zambiri, kutentha kwa ntchito kumakhala kokwera, ndiye kuti mbaliyo iyenera kukhala yokulirapo, kuti achepetse mwayi wokwatiwa pamene kutentha kwasinthidwa.Mu valavu yolowera pachipata, pali valavu yachipata chimodzi, valavu ya zipata ziwiri ndi valavu ya zipata zotanuka.Valavu yachipata cha chipata chimodzi imakhala ndi kukonzekera kosavuta komanso ntchito yodalirika, koma imafunika kulondola kwambiri pakona ya malo osindikizira, omwe ndi ovuta kukonza ndi kukonzanso, ndipo amatha kutsekedwa pamene kutentha kwasinthidwa.Ma valve a Double gate wedge gate amagwiritsidwa ntchito kwambiri pamapaipi amadzi ndi nthunzi.Ubwino wake ndi: kulondola kwa ngodya ya malo osindikizira kuyenera kukhala kotsika, ndipo kusintha kwa kutentha sikuli kophweka kuchititsa zochitika za ukwati.Pamene malo osindikizira avala, amatha kupachikidwa kuti alipidwe.Komabe, kukonzekera kotereku kuli ndi magawo ambiri, omwe ndi osavuta kulumikiza pakatikati pa viscous ndipo amakhudza kusindikiza.Chofunika kwambiri, zitsulo zam'mwamba ndi zam'munsi zimakhala zosavuta kuchita dzimbiri pambuyo pogwiritsira ntchito nthawi yayitali, ndipo nkhosa ndiyosavuta kugwa.Elastic gate wedge gate valve, yomwe ili ndi dongosolo losavuta la single gate wedge gate valve, imatha kutulutsa pang'ono pang'onopang'ono zotanuka kuti zilipirire kupatuka pamakona osindikizira pamwamba ndikuwongolera ukadaulo pogwiritsa ntchito * maubwino, ndipo osankhidwa ndi ambiri.
2. Malingana ndi kukonzekera kwa tsinde la valve, valve ya chipata ikhoza kugawidwa
1) Vavu yachipata cha tsinde yokwera: mtedza wa valavu uli pachivundikiro cha valve kapena chothandizira.Mukatsegula ndi kutseka chipata, tembenuzani mtedza wa valavu kuti mumalize kukweza tsinde la valve.Kukonzekera kotereku kumakhala kopindulitsa pakupaka ndodo ya valve, ndipo digiri yotsegulira ndi yotseka ndiyodziwikiratu, choncho imagwiritsidwa ntchito kwambiri.
2) Valavu yachipata chosakwera: nthiti ya valve ili m'thupi la valve ndipo imakhudza mwachindunji.Mukatsegula ndi kutseka nkhosa yamphongo, tembenuzani ndodo ya valve.Phindu la ndondomekoyi ndikuti kutalika kwa valve yachipata nthawi zonse kumakhala kosasinthika, kotero kuti malo a zipangizo ndi ochepa.Ndi oyenera mavavu pachipata ndi lalikulu awiri kapena anaumitsa zida danga.Kukonzekera kotereku kudzakhala ndi zizindikiro zotsegula ndi zotseka kuti zisonyeze kutsegulira ndi kutseka.Kuipa kwa ndondomekoyi ndikuti ulusi wa tsinde sungathe kutenthedwa, komanso umawonongeka mwachindunji ndi sing'anga ndikuwonongeka pang'ono.
The awiri a valavu pachipata ndi lalifupi
Kungoganiza kuti makulidwe a mayendedwe mu thupi la valavu ndi osiyana (nthawi zambiri m'mimba mwake pampando wa valve ndi wocheperako kuposa momwe amalumikizirana ndi flange), amatchedwa kufupikitsa njira.
Kuchepetsa m'mimba mwake kumatha kuchepetsa kukula kwa magawo ndi mphamvu yofunikira pakutsegula ndi kutseka.Pamodzi, imatha kukulitsa dongosolo la ntchito za magawo.
Pambuyo kuchepetsa kutengeka awiri.Kukana kwamadzi kumawonjezeka.
