Ivalvu yeplagi ye-Dbb yeMveliso yoShishino Ivalvu yeplagi yokuphakamisa iplagi Umthengisi wefektri waseTshayina Umvelisi
Yintoni ivalvu yeplagi ye-Dbb?
Isihlalo sentsimbi engatyiswangaIvalvu yeplagi ye-DbbZaphuhliswa kwiminyaka engaphezu kwama-80 eyadlulayo ukusombulula iingxaki zeevalvu ezikhoyo kwinkonzo yokuqhekeka kweekhataythali. Njengoko iivalvu zazisebenza kakuhle kule nkonzo, kwacetyiswa ukuba zisetyenziswe nakwezinye izicelo zehash kushishino lweekhemikhali kunye nepetrochemical. Njengoko iivalvu zazisebenza kakuhle kule nkonzo, kwacetyiswa ukuba zisetyenziswe nakwezinye izicelo zehash kushishino lweekhemikhali kunye nepetrochemical. Ukuchaza isizathu sokuba ivalvu ibe yimpumelelo kangaka, ngezantsi sichaze iimpawu zoyilo lwevalvu ukubonelela ngamandla ayo angaphakathi.
UMGAQO WOKUVULA NOKUVALA KWE-Ivalvu yeplagi ye-Dbb
Ukuvalwa kwevalvu:
- 1) jika i-handle lever nge-90 degrees ukuze wenze i-plug channel ijikeleze i-valve body channel
- 2) uze ujike ivili lesandla ukuze wehle iplagi, ukuze ivalvu ivalwe.
Iimpawu eziphambili zevalvu yeplagi ye-Dbb
Iimpawu kunye neenzuzo zeIvalvu yePlug yokuphakamisa.
- *Imveliso inesakhiwo esifanelekileyo, itywina elithembekileyo, ukusebenza kakuhle kunye nenkangeleko entle.
- *Inokusetyenziswa kwiiimeko zenkonzo ukuya kuthi ga650°C .
- *Izithintelo ezimbini zoomatshini, iinketho zeBlock kunye neBleed eziphindwe kabini.
- *Isihlalo esisuka kwisinyithi siye kwisinyithi, ubomi besihlalo obude, izihlalo ezikhuselekileyo ekungeneni ngqo xa zivuliwe kwaye zivaliwe.
- *Izihlalo eziqinileyo (ezithambileyo) zinokukhethwa ukuze zisebenze ngakumbi.
- *Akukho kuthambisa! Akukho kungcoliswa kwesixhobo sokucoca.
- *Izixhobo zeendawo kunye nobukhulu beeflanges zinokucwangciswa ngokufanelekileyo ngokwemeko yokusebenza yokwenyani yeemfuno zabathengi, ukuze kuhlangatyezwane neemfuno ezahlukeneyo zobunjineli.
