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

Zisindikizo zolimba zimapangidwa ndi chitsulo, monga ma gasket achitsulo, mphete zachitsulo, ndi zina zotero, ndipo kutseka kumachitika kudzera mukukangana pakati pa zitsulo. Chifukwa chake, magwiridwe antchito otseka ndi otsika, koma valavu yathu ya gulugufe ya ZFA yopangidwa ndi ma multilayer hard seal triple offset imatha kulephera kutulutsa. Zisindikizo zofewa zimapangidwa ndi zinthu zotanuka, monga rabara, PTFE, ndi zina zotero. Pazinthu zina zomwe zimakhala ndi kutentha kwambiri komanso kuthamanga kwambiri, zomwe sizingakwaniritse zofunikira pa ndondomekoyi, mavalavu a gulugufe olimba amatha kuthetsa vutoli.
Kusiyana pakati pa mavavu a gulugufe otsekedwa mwamphamvu ndi mavavu a gulugufe otsekedwa mofewa:
1. Kusiyana kwa kapangidwe kake: Ma valve a gulugufe ofewa nthawi zambiri amakhala ma valve a gulugufe apakati ndipomavavu awiri a gulugufe osakanikirana, pomwe ma valve a gulugufe olimba amakhala ma valve a gulugufe amodzi okha komansomavavu atatu a gulugufe ozungulira.
2. Kukana kutentha: Chisindikizo chofewa chimagwiritsidwa ntchito kutentha kwabwinobwino, Rabara ya -20℃~+120℃, PTFE ya -25℃~+150℃. Chisindikizo cholimba chingagwiritsidwe ntchito kutentha kochepa, kutentha kwabwinobwino, kutentha kwakukulu ndi malo ena, thupi la valavu ya gulugufe la LCB la -29°C -+180°C, thupi la valavu ya gulugufe la WCB ≤425°C, thupi la valavu ya gulugufe la Chitsulo Chosapanga Chitsulo ≤600°C.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. Kupanikizika: Chisindikizo chofewa chopanikizika pang'ono - kupanikizika kwabwinobwino PN6-PN25, chisindikizo cholimba chingagwiritsidwenso ntchito pamikhalidwe yapakati komanso yapamwamba monga PN40 ndi pamwambapa.
4. Kutsekeka bwino kwa ma valve: Valavu ya gulugufe yofewa yokhala ndi ma valve a gulugufe ndi valavu ya gulugufe yolimba yokhala ndi ma valve atatu imakhala ndi magwiridwe antchito abwino otsekeka bwino. Valavu ya gulugufe yolimba yokhala ndi ma valve atatu imatha kusunga ma valve abwino otsekeka bwino mumlengalenga wopanikizika kwambiri komanso kutentha kwambiri. Komabe, ma valve wamba otsekeka bwino amakhala ovuta kuti asatuluke konse.
5. Nthawi yogwira ntchito: Ma valve a gulugufe otseka mofewa amatha kukalamba komanso kutha, ndipo nthawi yawo yogwira ntchito ikuyembekezeka kukhala yochepa. Ma valve a gulugufe otsekedwa mwamphamvu amakhala ndi nthawi yayitali yogwira ntchito.
Poganizira makhalidwe omwe ali pamwambapa, valavu ya gulugufe yapakati ndi yoyenera kugwiritsidwa ntchito m'madzi abwino, zimbudzi, madzi a m'nyanja, madzi amchere, nthunzi, gasi lachilengedwe, chakudya, mankhwala, mafuta, kutsegula ndi kutseka mapaipi otulutsa mpweya ndi fumbi mbali zonse ziwiri, ndi ma asidi osiyanasiyana pa kutentha konse, kuthamanga ndi zinthu zosawononga. Mapaipi a alkali ndi ena amafunika kutsekedwa kwathunthu, mayeso osatulutsa mpweya, komanso kutentha kwa -10~150℃. Vavu ya gulugufe yolimba yotsekedwa ndi yoyenera pazochitika zomwe zili ndi kutentha kwambiri, kuthamanga kwambiri komanso zinthu zowononga, monga zida zowongolera ndi zotsekera m'mapaipi amafuta, gasi, asidi ndi alkali monga kutentha kwa m'mizinda, kupereka gasi, kupereka madzi, mafuta, petrochemical, makampani a mankhwala, zitsulo, ndi magetsi. Ndi malo abwino osinthira mavavu a zipata ndi mavavu a padziko lonse.
