Ma valve a zipata ndi ma valve a butterfly ndi ma valve awiri omwe amagwiritsidwa ntchito kwambiri.Amasiyana kwambiri malinga ndi momwe amapangira, njira zogwiritsidwira ntchito, komanso kusinthika kwazomwe zimagwirira ntchito.Nkhaniyi ithandiza ogwiritsa ntchito kumvetsetsa bwino kusiyana pakati pa ma valve a zipata ndi ma valve a butterfly.Ogwiritsa ntchito othandizira bwino kusankha ma valve.
Tisanafotokoze kusiyana pakati pa valavu yachipata ndi valavu ya butterfly, tiyeni tiwone matanthauzo ake awiriwa.Mwinamwake mungapeze kusiyana pakati pa awiriwa mosamala kuchokera ku tanthauzo.
Vavu yachipata, monga momwe dzinalo likusonyezera, imatha kudula sing'anga mu payipi ngati chipata, ndipo ndi mtundu wa valve yomwe tonse timagwiritsa ntchito popanga ndi moyo.Kutsegula ndi kutseka gawo la chipata valavu amatchedwa chipata, ndi chipata chimayenda mmwamba ndi pansi, ndi kayendedwe kake ndi perpendicular kwa otaya malangizo sing'anga mu payipi madzimadzi;valve yachipata ndi valve yodulidwa, yomwe imatha kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu, ndipo kutuluka sikungasinthidwe.
Valve ya butterfly, yomwe imadziwikanso kuti flap valve.Mbali yake yotsegula ndi yotseka ndi mbale yagulugufe yooneka ngati diski, yomwe imakhazikika pa tsinde la valve ndikuzungulira mozungulira valavu ya valve kuti izindikire kutsegula ndi kutseka.Mayendedwe a valavu ya gulugufe ndi kuzungulira mu situ, ndipo amangofunika kuzungulira 90 ° kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu.Kuphatikiza apo, mbale yagulugufe ya valavu yagulugufe palokha ilibe luso lodzitsekera, ndipo chotsitsa cha mphutsi chiyenera kuyikidwa pa tsinde la valavu.Ndi iyo, mbale yagulugufe imakhala ndi mphamvu yodzitsekera yokha, ndipo imathanso kupititsa patsogolo ntchito ya gulugufe.
Podziwa tanthauzo la valve yachipata ndi valavu yagulugufe, kusiyana pakati pa valavu yachipata ndi valavu ya butterfly ikufotokozedwa pansipa:
1. Kusiyana kwa luso la masewera
M'matanthauzo omwe ali pamwambawa, timamvetsetsa kusiyana kwa njira ndi kayendetsedwe ka kayendedwe ka zipata ndi ma valve a butterfly.Kuonjezera apo, ma valve a zipata amatha kutsegulidwa kwathunthu ndi kutsekedwa kwathunthu, kotero pamene atsegulidwa kwathunthu, ma valve a zipata amakhala ndi kukana kwakung'ono;Mavavu agulugufe Pamalo otseguka, makulidwe a valavu yagulugufe kumapangitsa kukana kwa sing'anga yoyenda.Kuonjezera apo, valve yachipata imakhala ndi kutalika kwapamwamba kutsegulira, kotero kuti kutsegula ndi kutseka kumachedwa;pamene valavu ya butterfly imatha kutsegulidwa ndi kutsekedwa ndi kusinthasintha kokha 90 °, kotero kuti kutsegula ndi kutseka kufulumira.
2. Kusiyana pakati pa ntchito ndi ntchito
Valve ya pachipata imakhala ndi ntchito yabwino yosindikiza, motero imagwiritsidwa ntchito kwambiri m'mapaipi omwe amafunikira kusindikiza mwamphamvu ndipo safunikira kusinthidwa mobwerezabwereza kuti adutse sing'anga yozungulira.Valve yachipata sichingagwiritsidwe ntchito kusintha kayendedwe ka kayendedwe kake.Kuonjezera apo, chifukwa kutsegula ndi kutseka kwa valve yachipata kumachedwa, sikuli koyenera kuti payipi iyenera kudulidwa mwamsanga.Kugwiritsa ntchito ma valve a butterfly ndikokulirapo.Ma valve a butterfly sangagwiritsidwe ntchito kokha kudula, komanso kukhala ndi ntchito yokonza kukula kwa kayendedwe kake.Kuonjezera apo, valavu ya butterfly imatsegula ndi kutseka mwamsanga, ndipo imathanso kutsegulidwa ndi kutsekedwa kawirikawiri, makamaka yoyenera kugwiritsidwa ntchito pazochitika zomwe zimafuna kutsegula kapena kutseka mwamsanga.
Kukula kwa valavu ya butterfly ndi yaying'ono kuposa ya valve ya chipata, ndipo kulemera kwake kulinso kopepuka kuposa kwa valve yachipata.Choncho, m'madera ena okhala ndi malo ochepa oyikapo, tikulimbikitsidwa kugwiritsa ntchito valavu ya butterfly yopulumutsa malo.Pakati pa ma valve akuluakulu, valavu ya butterfly ndiyomwe imagwiritsidwa ntchito kwambiri, ndipo tikulimbikitsidwanso kugwiritsa ntchito valavu ya butterfly mu payipi yapakatikati yomwe ili ndi tinthu tating'ono ta zonyansa.
Posankha ma valve muzochitika zambiri zogwirira ntchito, ma valve a butterfly asintha pang'onopang'ono mitundu ina ya ma valve ndikukhala chisankho choyamba cha ogwiritsa ntchito ambiri.
3. Kusiyana kwa mtengo
Pansi pa kukakamizidwa komweko komanso mtundu womwewo, mtengo wa valve yachipata ndi wapamwamba kuposa wa valavu ya butterfly.Komabe, valavu ya gulugufe ikhoza kukhala yaikulu kwambiri, ndipo mtengo wa valavu ya butterfly yayikulu si yotsika mtengo kuposa ya valve yachipata.
