1. Zomwe zimapangidwira
Pali kusiyana koonekeratu pakati pa gulu A gulugufe valavu ndi gulu B gulugufe vavu mu kapangidwe.
1.1 Gulu A mavavu agulugufe ndi "concentric", nthawi zambiri amakhala ndi mawonekedwe osavuta, opangidwa ndi thupi la valavu, valavu disk, mpando wa valve, shaft ya valve ndi chipangizo chotumizira. Disiki ya valve imakhala yofanana ndi disc ndipo imazungulira kuzungulira shaft ya valve kuti iwononge kutuluka kwa madzi.
1.2 Mosiyana, ma valve a gulugufe a gulu B ndi mtundu wa "offset", kutanthauza kuti shaft imachotsedwa ku diski, imakhala yovuta kwambiri ndipo ikhoza kukhala ndi zisindikizo zowonjezera, zothandizira, kapena zigawo zina zogwirira ntchito kuti apereke ntchito yosindikiza komanso kukhazikika.
2. Azovuta m'malo osiyanasiyana ogwira ntchito
Chifukwa cha kusiyana kwa kamangidwe, gulu A gulugufe valavu ndi gulu B gulugufe valavu amagwiritsidwa ntchito zosiyanasiyana ntchito.
2.1 Gulu A mavavu agulugufe amagwiritsidwa ntchito kwambiri mu kuthamanga otsika, lalikulu m'mimba mwake dongosolo mapaipi, monga ngalande, mpweya wabwino ndi mafakitale ena, chifukwa cha dongosolo lake losavuta, kakulidwe kakang'ono, kulemera kuwala ndi zina.
2.2 Gulu B lagulugufe ndiloyenera kwambiri kugwiritsidwa ntchito ndi zofunikira zosindikizira kwambiri komanso kuthamanga kwakukulu kwapakati, monga mankhwala, mafuta, gasi ndi mafakitale ena.
3. Kuyerekeza kwa magwiridwe antchito
3.1 Kusindikiza: Mavavu agulugufe a gulu B nthawi zambiri amakhala abwino kuposa ma valve a gulugufe A gulugufe akamasindikiza, chifukwa cha kapangidwe kawo kovutirapo komanso kapangidwe kake ka chisindikizo. Izi zimathandiza gulu B gulugufe valavu kusunga bwino kusindikiza zotsatira m'madera ovuta monga kuthamanga ndi kutentha kwambiri.
3.2 Kuthamanga kwa mphamvu: Kuthamanga kwa gulu A gulugufe valavu ndi yolimba, chifukwa mapangidwe a disk disk ndi ophweka, kukana kwa madzi akudutsa ndi kochepa. Gulu B gulugufe vavu zingakhudze kuyenda bwino kwa madzimadzi pamlingo wakutiwakuti chifukwa cha dongosolo zovuta.
3.3 Kukhalitsa: Kukhazikika kwa gulu B mavavu agulugufe nthawi zambiri kumakhala kokulirapo, chifukwa kapangidwe kake kamangidwe ndi kusankha kwazinthu kumayang'ana kwambiri kukhazikika kwanthawi yayitali komanso kukana dzimbiri. Ngakhale gulu A gulugufe valavu n'zosavuta dongosolo, zikhoza kukhala pachiwopsezo kwambiri kuwononga m'madera ena ovuta.
4. Kugula njira zodzitetezera
Pogula gulu A ndi gulu B mavavu agulugufe, zinthu zotsatirazi ziyenera kuganiziridwa:
4.1 Mikhalidwe yogwirira ntchito: Sankhani gulu loyenera la valavu ya butterfly malinga ndi kuthamanga kwawo, kutentha, sing'anga ndi zina za dongosolo la mapaipi. Mwachitsanzo, mavavu agulugufe a gulu B ayenera kuperekedwa patsogolo pa kupanikizika kwambiri komanso kutentha kwambiri.
4.2 Zofunikira zogwirira ntchito: Zofunikira zowunikira bwino, monga zofunikira pakutsegula ndi kutseka mwachangu, kugwira ntchito pafupipafupi, ndi zina, kusankha mawonekedwe oyenera a vavu agulugufe ndi njira yopatsira.
4.3 Economy: Pansi pokwaniritsa zofunikira zogwirira ntchito, ganizirani za chuma cha gulugufe, kuphatikizapo ndalama zogulira, mtengo wokonza, ndi zina zotero, gulu A gulugufe nthawi zambiri zimakhala zotsika mtengo, pamene gulu B mavavu agulugufe, ngakhale bwino mu ntchito, ingakhalenso yokwera mtengo.
