M'matauni, zomangamanga ndi ntchito zamabizinesi operekera madzi ndi ngalande, mavavu apakati ndi otsika amagwiritsidwa ntchito kwambiri, makamaka otsika kwambiri-diameter.mavavu (mavavu otsika kwambiri amatanthawuza mavavu okhala ndi mphamvu yadzina PN ¡Ü 1.6Mpa). Momwe mungasiyanitsire ma valve otsika kwambiri ndi ma valve opanikizika / omwe ali otetezeka / ofanana ndi chitoliro? Magazini iyi ikupatsani yankho latsatanetsatane!
1¡¢ Momwe mungasiyanitsire pakati pa valve low pressure valve ndi medium pressure valve
1. Kupanikizika ndi kutuluka ndizosiyana
Kuthamanga kwakukulu ndi kutuluka kwakukulu kwa valve yapakati; Valve yotsika kwambiri imakhala ndi mphamvu yotsika komanso yothamanga pang'ono, yomwe imatha kuwongolera kuthamanga kwa tanki ndikutulutsa mpweya pang'onopang'ono.
2. Ntchito zosiyanasiyana
Valavu yotsika kwambiri imagwiritsidwa ntchito ngati chitofu cha gasi kapena chotenthetsera madzi, ndipo valavu yapakatikati imagwiritsidwa ntchito pachitofu chapakati komanso champhamvu kwambiri.
3. Zosiyanasiyana zachitetezo
Chifukwa cha kuthamanga kwambiri komanso kuthamanga kwachangu, valve yothamanga yapakati imatha kuwonongeka chifukwa cholephera kutulutsa mpweya mumlengalenga. Valavu yotsika kwambiri imatha kuwongolera kuthamanga kwa tanki ndikutulutsa mpweya pang'onopang'ono. Ngakhale mutamasula zomangira zosinthira, gasi sakhala wamkulu kwambiri.
2¡¢ Zomwe zimakhala zotetezeka, zotsika kwambirivalavukapena valavu yapakati
@Osadziwika
Valavu yotsika kwambiri yomwe imagwiritsidwa ntchito pamoto woyaka moto ndi woopsa kwambiri, chifukwa sungathe kukwaniritsa zofunikira zamoto, choncho zikhoza kuyambitsa moto. Valavu yapakati kapena yothamanga kwambiri ingagwiritsidwe ntchito. Ngati valavu yotsika kwambiri imagwiritsidwa ntchito pazitsulo wamba, zochitika zidzachitikanso pamene kupanikizika kuli kwakukulu kwambiri DC12V¡¢DC24V¡£ Kuthamanga kwadzina kochepa, komwe kumayenera kusankhidwa molingana ndi kukakamizidwa kwa payipi, PN16 wamba. Ngati valavu yotsika kwambiri imasankhidwa pansi pa zofunikira zamphamvu, ndizosatetezeka.
@Kusadziwika
Zitofu zamagasi apanyumba nthawi zambiri zimagwiritsa ntchito valavu yotsika, yomwe nthawi zambiri imakhala 2800pa. Kuthamanga kwapakati kumagwiritsidwa ntchito ndi masitovu amalonda, ndipo ma valve othamanga kwambiri sayenera kugwiritsidwa ntchito. Zopangira gasi wamba zimakhala ndi mphamvu yofananira. Ngati agwiritsidwa ntchito mopitilira kuchuluka kwa mphamvu, sangathe kuyatsa moto, ndipo ngozi zazikulu zachitetezo zitha kuchitika.
3¡¢ Kodi valavu yotsika kwambiri imakhala yofanana ndi chitoliro chapakati cha valve
Nthawi zambiri, magawo ogawa ndi 1.6Mpa ndi 10.0MPa. The otsika-anzanu payipi ndi amene ali ndi mamangidwe kuthamanga zosakwana kapena wofanana 1.6Mpa, sing'anga kuthamanga payipi ndi amene ali ndi mapangidwe kuthamanga kuposa 1.6Mpa ndi zosakwana kapena wofanana 10.0MPa, ndi payipi mkulu-anzanu. ndi yomwe ili ndi mphamvu yapangidwe yokulirapo kapena yofanana ndi 10.0MPa.
Mapaipi opondereza amatanthauza mapaipi onse omwe amanyamula kupanikizika kwa mkati kapena kunja. Mosasamala kanthu za sing'anga mu payipi, zovuta zina za valve zimathanso kusiyanitsa molingana ndi izi
1. Low kuthamanga mapaipi injiniya kuthamanga
2. Kuthamanga kwa mapaipi apakati apakati amagwira ntchito ndi 1.6-6.4mpa
3. Kuthamanga kwapaipi yapaipi yaukadaulo> 10MPa.
