Kodi pali kusiyana kotani pakati pa valavu ya gate ndi butterfly valve?

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.

    Chipata cha valve,monga dzinalo likusonyezera, akhoza kudula sing'anga mu payipi ngati chipata, ndipo ndi mtundu wa vavu kuti tonse ntchito kupanga 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 tsinde la valve kuti likwaniritse kutsegula ndi kutseka.Mayendedwe a valavu ya gulugufe ndi kusinthasintha m'malo mwake, 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.

kuti timamvetsetsa matanthauzo a ma valve a zipata ndi ma valve agulugufe,lolani's kuwonetsa kusiyana pakati pa ma valve a zipata ndi ma valve a butterfly:

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, kukana kwa ma valve a zipata kumakhala kochepa;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 kwa ntchito ndi ntchito

Ma valve a zipata amakhala ndi ntchito yabwino yosindikiza, choncho amagwiritsidwa ntchito nthawi zambiri m'mapaipi omwe amafunikira kusindikizidwa mwamphamvu ndipo safunikira kutsegulidwa ndi kutsekedwa pafupipafupi kuti adutse sing'anga yozungulira.Valve yachipata sichingagwiritsidwe ntchito kuwongolera kuyenda.Kuonjezera apo, chifukwa kutsegula ndi kutseka kwa valve yachipata kumachedwa, sikuli koyenera mapaipi omwe amafunikira kutsekedwa mwadzidzidzi.Kugwiritsa ntchito ma valve a butterfly ndikokulirapo.Mavavu agulugufe sangagwiritsidwe ntchito podula, komanso amakhala ndi ntchito yosinthira kuthamanga.Kuphatikiza apo, valavu yagulugufe imatsegula ndikutseka mwachangu komanso imatha kutsegulidwa ndikutsekedwa pafupipafupi.Ndiwoyenera kugwiritsidwa ntchito nthawi zomwe zimafuna kutsegula kapena kutseka mwachangu.

Mavavu agulugufe ndi ang'onoang'ono kukula kwake komanso kulemera kwake kuposa mavavu a pachipata, kotero m'malo ena okhala ndi malo ochepa oyikapo, tikulimbikitsidwa kugwiritsa ntchito valavu yagulugufe yopulumutsa malo.Pakati pa ma valve akuluakulu, ma valve a butterfly ndi omwe amagwiritsidwa ntchito kwambiri.Mavavu agulugufe amalimbikitsidwanso kuti azinyamula mapaipi owulutsa okhala ndi zonyansa zazing'ono.

Pankhani ya kusankha ma valve pansi pazigawo zambiri zogwirira ntchito, ma valve a butterfly asintha pang'onopang'ono mitundu ina ya ma valve ndikukhala chisankho choyamba kwa ogwiritsa ntchito ambiri.

3. Kusiyana kwa mtengo

Pansi pa kukakamizidwa komweko ndi caliber, mtengo wa valve pachipata ndi wapamwamba kuposa wa agulugufe.Komabe, m'mimba mwake mavavu agulugufe akhoza kukhala aakulu kwambiri, ndipo mtengo wa mavavu agulugufe lalikulu m'mimba mwake si otsika mtengo kuposa mavavu pachipata.
