Kusiyana pakati pa valavu ya gulugufe yofewa ndi valavu ya gulugufe yolimba

Valavu ya gulugufe yolimba yosindikizira

Kutseka kolimba kwa valavu ya gulugufe kumatanthauza kuti mbali zonse ziwiri za kutseka zimapangidwa ndi zitsulo kapena zinthu zina zolimba. Kutseka kwa mtundu uwu wa chisindikizo ndi koipa, koma kumakhala ndi kukana kutentha kwambiri, kukana kuwonongeka komanso magwiridwe antchito abwino amakina. Mwachitsanzo: chitsulo+chitsulo; Chitsulo+mkuwa; Chitsulo+grafiti; Chitsulo+chitsulo chosungunula. Chitsulo pano chingakhalenso chitsulo chosungunula, chitsulo chosungunula, chitsulo chosungunula kapena aloyi yopangira pamwamba ndi kupopera.

Valavu yofewa ya gulugufe

Chisindikizo chofewa cha valavu ya gulugufeamatanthauza kuti mbali imodzi ya chisindikizo chapangidwa ndi zinthu zachitsulo, ndipo mbali inayo imapangidwa ndi zinthu zotanuka zopanda chitsulo. Kutseka kwa mtundu uwu wa chisindikizo ndi kwabwino, koma sikulimbika ku kutentha kwambiri, ndikosavuta kuvala, ndipo kuli ndi magwiridwe antchito oipa amakina, monga: chitsulo+labala; Chitsulo+PTFE, ndi zina zotero.

Mpando wofewa wotseka umapangidwa ndi zinthu zopanda chitsulo zomwe zimakhala ndi mphamvu zina, kuuma komanso kukana kutentha. Ndi ntchito yabwino, imatha kutayikiratu, koma nthawi yake yogwirira ntchito komanso kusinthasintha kutentha ndizochepa. Chisindikizo cholimba chimapangidwa ndi chitsulo, ndipo magwiridwe antchito otseka ndi otsika. Ngakhale opanga ena amanena kuti palibe kutuluka kwa madzi komwe kungatheke. Chisindikizo chofewa sichingakwaniritse zofunikira pazida zina zowononga. Chisindikizo cholimba chingathe kuthetsa vutoli, ndipo zisindikizo ziwirizi zimatha kugwirizana. Ponena za magwiridwe antchito otseka, kutseka kofewa ndikwabwino, koma tsopano magwiridwe antchito otseka otseka mwamphamvu amathanso kukwaniritsa zofunikira zomwezo. Ubwino wa chisindikizo chofewa ndi magwiridwe antchito abwino otseka, pomwe zovuta zake ndi kukalamba mosavuta, kuwonongeka komanso nthawi yochepa yogwirira ntchito. Chisindikizo cholimba chimakhala ndi nthawi yayitali yogwirira ntchito, koma magwiridwe antchito ake otseka ndi oyipa kuposa a chisindikizo chofewa.

Kusiyana kwa kapangidwe kake makamaka ndi motere:

1. Kusiyana kwa kapangidwe ka nyumba

Ma valve a gulugufe otsekedwa bwinoMa valve a gulugufe otsekeredwa kwambiri amakhala amtundu wapakati, pomwe ma valve a gulugufe otsekeredwa olimba nthawi zambiri amakhala amtundu umodzi, wachiwiri komanso wachitatu.

2. Kukana kutentha

Chisindikizo chofewa chimagwiritsidwa ntchito kutentha kwabwinobwino. Chisindikizo cholimba chingagwiritsidwe ntchito kutentha kochepa, kutentha kwabwinobwino, kutentha kwakukulu ndi malo ena.

3. Kupanikizika

Chisindikizo chofewa chimagwira ntchito mochepa - chisindikizo chachibadwa, cholimba chingagwiritsidwenso ntchito m'mikhalidwe yogwirira ntchito monga yapakati ndi yapamwamba.

4. Kutseka magwiridwe antchito

Kutseka kwa valavu yofewa yotsekera gulugufe ndi valavu yolimba yotsekera gulugufe ya tri eccentric ndikwabwino. Vavu ya gulugufe ya tri eccentric imatha kusunga kutseka bwino pansi pa kupanikizika kwakukulu komanso kutentha kwambiri.

Poganizira makhalidwe omwe ali pamwambapa,vavu yofewa yosindikiza gulugufeNdi yoyenera kutsegula ndi kutseka mapaipi otsegula mpweya ndi fumbi, kukonza madzi, makampani opanga magetsi, mafuta, makampani opanga mankhwala ndi mafakitale ena. Valavu yotseka ya gulugufe yolimba imagwiritsidwa ntchito makamaka potenthetsera, kupereka mpweya, gasi, mafuta, asidi ndi malo okhala ndi alkali.

Pogwiritsa ntchito kwambiri valavu ya gulugufe, mawonekedwe ake osavuta kukhazikitsa, kukonza kosavuta komanso kapangidwe kosavuta zimaonekera kwambiri.Ma valve a gulugufe otsekedwa ndi magetsi, ma valve a gulugufe otsekedwa ndi mpweya, ma valve a gulugufe otsekedwa ndi mphamvu, ndi zina zotero, akuyamba kusintha ma valve a chipata chamagetsi, ma valve a globe, ndi zina zotero nthawi zambiri.
