Valavu Yokhala ndi Mpeni wa Polyurethane Wokhala ndi Mizere Yokwanira Yosagwira Ntchito

Kodi valavu ya chipata cha polyurethane mpeni ndi chiyani?

Valavu yotchingira mpeni wa polyurethaneamatanthauza valavu ya chipata cha mpeni yokhala ndi chisindikizo cha mpando cha valavu ya polyurethane.Polyurethane (PU)Ili ndi makhalidwe monga kukana mafuta, kukana kuvala, kukana kutentha kochepa, kukana ukalamba, kuuma kwambiri, kusinthasintha kwabwino komanso kugwira ntchito bwino polimbana ndi poizoni. Nthawi zambiri imagwiritsidwa ntchito popanga tinthu tolimba kwambiri komanso mapaipi apakati okhala ndi mpweya ndi madzi. Ili ndi magwiridwe antchito abwino otsekera komanso kukana kuvala mwamphamvu.

Polyurethane imadziwika kuti "raba yosatha ntchito". Kukana kwake mafuta sikotsika poyerekeza ndi rabara ya nitrile ndipo ndi kofanana ndi rabara ya polysulfide. Ndi yoyenera kwambiri mapaipi osiyanasiyana apakatikati omwe amafunika kutsekedwa kwambiri komanso kuwonongeka kwa tinthu tating'onoting'ono tolimba kwambiri.

Zambiri Zamalonda za Valavu ya Chipata cha Mpeni wa Polyurethane

Miyezo ya PU Mpeni Chipata Valavu

Mawonekedwe a Kapangidwe:

Valavu ya Chipata cha Mpeni wa Polyurethanezomwe zimapangitsa kuti ikhale imodzi mwa zipangizo zabwino kwambiri zosagwira ntchito. Valvu yathu ya Polyurethane Knife Gate Valve (NSW) ili ndi urethane yapamwamba kwambiri, yomwe imaposa nthawi yogwiritsidwa ntchito ngati rabara ya chingamu ndi nsalu ina iliyonse yofewa, kapena zinthu zina zofewa.

1.Kutaya konse: Thupi la valavu ya urethane yokhala ndi mzere wokwanira komanso chisindikizo cha chipata cha elastomer chopangidwa molimba chimaletsa kutuluka kwa madzi kosatha kutsekeka kwa valavu komanso thupi la valavu palokha panthawi yogwira ntchito.

2.Nthawi yayitali yogwiritsidwa ntchito: Ma urethane liners abwino kwambiri osagwa, ndi zipata zolimba za mpeni wosapanga dzimbiri komanso kapangidwe kapadera ka valavu yokha kamapereka moyo wautali kwambiri.

3.Kutseka mbali zonse ziwiri: Pamene kubwerera kwa magazi kukuchitika, NSW ingagwiritsidwenso ntchito ngati choletsa.

4.Kapangidwe kodzitsuka: Pakutseka valavu, chipata chotchinga cha mpeni chopindika chimatumiza matope oyenda kupita ku mpando wa urethane wopindika, kugwedezeka kumayamba ndikuwonjezera madzi kenako amachotsa matopewo pansi pa urethane pamene chipatacho chikukhazikika pampando.

5. Kumanganso bwino: Pamene kukonzanso komaliza kukufunika, zida zosweka (urethanes, zisindikizo za zipata, zipata za mipeni) zonse zitha kusinthidwa m'munda. Ma valve ndi ziwalo zina zitha kugwiritsidwanso ntchito.

Zosankha

1. Mphete ya Mpando (Zingwe):Mitundu yosiyanasiyana ya urethanes ikupezeka.

2. Zipata za Valve:Zipata za SS304 zokhala ndi zokutidwa ndi chromium zolimba ndizokhazikika. Ma alloy ena amapezeka (SS316, 410, 416, 17-4PH…) Palinso zokutidwa ndi zipata zomwe mungasankhe.

3. PN10, PN16, PN25, 150LB, zilipo.

4. Pali ma actuator osankha omwe alipo.
