Chisindikizo chofewa ndi chisindikizo cholimba cha valavu ya chipata

1. Kodi chisindikizo chofewa ndi cholimba cha valavu ya chipata ndi chiyani?

Ma valve otsekedwa bwino amagwiritsa ntchito zinthu zotanuka zosagwiritsa ntchito chitsulo monga rabara ndi PTFE ngati zisindikizo, zomwe zimakhala zofewa komanso zolimba pamodzi ndi mpando wa valve wachitsulo. Amadalira kusintha kwa elastic kwa zinthu zotsekera kuti adzaze mpata ndikutseka, monga momwe zasonyezedwera pa Chithunzi 01. Ma valve otsekedwa bwino ali ndi kapangidwe kotseka kachitsulo kokha. Malo otsekera ndi nthaka yolondola komanso pamwamba ndi alloy yolimba, ndipo kutseka kumachitika ndi chitsulo chomangirira, monga momwe zasonyezedwera pa Chithunzi 02.

2. Kodi kusiyana kwakukulu pakati pa t ndi kotani?wakeawiri?

Kusiyana kwakukulu kuli mu zipangizo zotsekera ndi momwe zimagwirira ntchito. Zisindikizo zofewa zimakhala ndi kusinthasintha kwabwino ndipo zimatha "kutulutsa madzi osafunikira", koma sizimalimbana ndi kutentha kwambiri komanso kuwonongeka. Zisindikizo zolimba zimalimbana ndi kutentha kwambiri, kupsinjika kwambiri, komanso kukokoloka kwa nthaka, koma zimakhala ndi ndalama zambiri zokonzera ndipo zimakhala zovuta kupeza madzi osafunikira konse.

3. Kodi kutentha kwakukulu komwe avalavu yofewa yotseka chitsekoKodi angathe kupirira?

Kawirikawiri, malire apamwamba a kutentha koyenera kwa zinthu zofewa zotsekera ndi pafupifupi 120°C. Rabala ya EPDM yodziwika bwino ndi pafupifupi 120℃, PTFE ndi pafupifupi 200℃ (koma kupanikizika kuyenera kuchepetsedwa). Ngati zinthu zotsekera zipitirira malire awa, zinthu zotsekera zidzafewa, zidzasokonekera kapena zidzakalamba ndikulephera.

4. Chitinima valve a chipata cholimbaKodi palibe kutayikira konse?

Zisindikizo zachitsulo zogwiritsidwa ntchito bwino zimatha kubweretsa kutayikira kwakukulu (monga ANSI Level V kapena Level VI), koma nthawi zambiri zimakhala zovuta kupeza "kutayikira konse kopanda kutayikira" monga zisindikizo zofewa. Komabe, m'mikhalidwe yovuta yogwirira ntchito monga kutentha kwambiri ndi kuthamanga kwambiri, kutseka kolimba ndiye njira yokhayo yodalirika

5. Kodi mungasankhe bwanji chisindikizo chofewa kapena cholimba?

Mwachidule: zisindikizo zofewa zimasankhidwa kuti zigwiritsidwe ntchito monga kutentha kwabwinobwino kwa madzi, zimbudzi, ndi gasi zomwe sizimafuna kutuluka madzi ndi zinthu zoyera; zisindikizo zolimba zimasankhidwa kuti zigwiritsidwe ntchito m'mafakitale zomwe zimaphatikizapo nthunzi yotentha kwambiri, mafuta opanikizika kwambiri, tinthu tating'onoting'ono, kapena zinthu zowononga.

6. Kodi nthawi yogwira ntchito ya valavu yofewa yotsekera chitseko ndi yayifupi kuposa ya valavu yolimba?

Sizikudziwika. Pakagwiritsidwa ntchito moyenera, nthawi yogwira ntchito ya chisindikizo chofewa imatha kukhala yayitali kwambiri; komabe, ngati chisindikizo chofewa chikugwiritsidwa ntchito m'malo okhala ndi tinthu tating'onoting'ono kapena pamalo otentha kwambiri, nthawi yake idzafupikitsidwa kwambiri. Poganizira za kusankha kolondola, zonse ziwiri zimatha kukhala ndi nthawi yogwira ntchito yokwanira.

7. Kodi pali kusiyana kwakukulu pamtengo pakati pa mitundu iwiri yosindikizira?

Kawirikawiri, ma valve otsekedwa bwino amakhala ndi ndalama zochepa zopangira ndipo ndi otsika mtengo;ma valve a chipata cholimbandi okwera mtengo kwambiri chifukwa cha mtengo wokwera wa zinthu komanso njira zovuta zokonzera (monga kupukuta pamwamba pa zinthu zosawonongeka, kupukuta molondola).

8. Kodi kusiyana kwake ndi kotani pa kukonza?

Kusamalira ma valve otsekedwa bwino ndi kosavuta, ingosinthani mphete yotsekera; pamwamba pa ma valve otsekedwa bwino kwambiri pakawonongeka, kukonza pamalopo kumakhala kovuta, ndipo nthawi zambiri kumafunika kubwezedwa kwa wopanga waluso kuti akapere kapena kukonzanso.

TWS: Valavu yofewa yotseka chitsekoNdi yoyenera kugwiritsidwa ntchito m'madzi oyera, gasi ndi zina ndipo singathe kutayikira; chisindikizo cholimba chimagwiritsidwa ntchito pa kutentha kwambiri komanso kuthamanga kwambiri.Ma valve a gulugufe, ma valve owunikirandivalavu yotulutsa mpweyaamasankhidwa kutengera mfundo imeneyi, poganizira momwe zimagwirira ntchito potseka, kukana kutentha, komanso kukana kuthamanga kwa magazi.
