1. Kapangidwe kake
Pali kusiyana koonekeratu pakati pa valavu ya gulu la gulu la gulu la gulu la A ndi valavu ya gulu la gulu la B m'mapangidwe ake.
1.1 Gulu Ma valve a gulugufe ndi amtundu wa "concentric", nthawi zambiri amakhala ndi kapangidwe kosavuta, kokhala ndi thupi la valve, diski ya valve, mpando wa valve, shaft ya valve ndi chipangizo chotumizira. Disiki ya valve imakhala yofanana ndi disc ndipo imazungulira mozungulira shaft ya valve kuti ilamulire kuyenda kwa madzi.
1.2 Mosiyana ndi zimenezi, ma valve a gulugufe a gulu B ndi amtundu wa "offset", zomwe zikutanthauza kuti shaft imachotsedwa pa diski, ndi yovuta kwambiri ndipo ikhoza kukhala ndi zisindikizo zowonjezera, zothandizira, kapena zigawo zina zogwirira ntchito kuti zipereke magwiridwe antchito abwino komanso kukhazikika.
2. Antchito zosiyanasiyana
Chifukwa cha kusiyana kwa kapangidwe kake, valavu ya gulu la gulu A ndi valavu ya gulu B zimagwiritsidwanso ntchito m'malo osiyanasiyana ogwirira ntchito.
2.1 Gulu A ma valve a gulugufe amagwiritsidwa ntchito kwambiri mu mapaipi opanikizika pang'ono, okhala ndi mainchesi akuluakulu, monga kukhetsa madzi, mpweya wabwino ndi mafakitale ena, chifukwa cha kapangidwe kake kosavuta, kukula kwake kochepa, kulemera kwake kopepuka ndi zina.
2.2 Gulu B gulugufe valavu ndi yoyenera kwambiri kugwiritsa ntchito ndi zofunikira pakutseka kwambiri komanso kuthamanga kwakukulu kwapakati, monga mankhwala, petulo, gasi wachilengedwe ndi mafakitale ena.
3. Kuyerekeza ubwino wa magwiridwe antchito
3.1 Kugwira ntchito bwino kwa ma valve a gulu B a gulu B nthawi zambiri amakhala abwino kuposa ma valve a gulu A a gulu A pakugwira ntchito bwino kwa ma valve, chifukwa cha kapangidwe kake kovuta komanso kapangidwe kake kowonjezera ka ma valve. Izi zimathandiza kuti valavu ya gulu B ikhale ndi mphamvu yabwino yotsekera m'malo ovuta monga kuthamanga kwambiri komanso kutentha kwambiri.
3.2 Kuchuluka kwa madzi: Kuchuluka kwa madzi mu valavu ya gulu la ...
3.3 Kulimba: Kulimba kwa mavavu a gulu la B nthawi zambiri kumakhala kokwera, chifukwa kapangidwe kake ndi kusankha zinthu kumaika chidwi kwambiri pa kukhazikika kwa nthawi yayitali komanso kukana dzimbiri. Ngakhale kuti valavu ya gulu la A ndi yosavuta, ingakhale yotetezeka kwambiri kuwonongeka m'malo ena ovuta.
4. Malangizo Ogulira
Pogula ma valve a gulugufe a gulu A ndi gulu B, zinthu zotsatirazi ziyenera kuganiziridwa:
4.1 Mikhalidwe Yogwirira Ntchito: Sankhani gulu loyenera la valavu ya gulugufe malinga ndi kuthamanga kwawo, kutentha, pakati ndi zina zomwe zimachitika mu dongosolo la mapaipi. Mwachitsanzo, mavalavu a gulugufe a gulu B ayenera kupatsidwa mwayi waukulu m'malo opanikizika kwambiri komanso kutentha kwambiri.
4.2 Zofunikira pakugwiritsa ntchito: Zofunikira pakugwiritsa ntchito bwino, monga zofunika pakutsegula ndi kutseka mwachangu, kugwira ntchito pafupipafupi ndi zina zotero, kuti musankhe kapangidwe koyenera ka valavu ya gulugufe ndi njira yotumizira.
4.3 Zachuma: Poganizira za kukwaniritsa zofunikira pa ntchito, ganizirani za ndalama zomwe valavu ya gulugufe imagwiritsira ntchito, kuphatikizapo ndalama zogulira, ndalama zosamalira, ndi zina zotero, mavalavu a gulugufe nthawi zambiri amakhala otsika mtengo, pomwe mavalavu a gulugufe a gulugufe, ngakhale kuti amagwira ntchito bwino, angakhalenso okwera mtengo.
