Ivalve yeplagi yeDbb yoShishino Phakamisa ivalve yeplagi yaseTshayina umniki-mveliso waseTshayina Umenzi
Yintoni i-Dbb plug valve?
Intsimbi engathanjiswanga ihleliIvalve yeplagi yeDbbzaphuhliswa kwiminyaka engama-80 eyadlulayo ukusombulula iingxaki ngeevalvu ezikhoyo kwinkonzo yokuqhekeka kwe-catalyst.Njengoko iivalvu zangaphambili kakuhle kule nkonzo kwaye kwacetyiswa ukuba zisetyenziswe kwezinye izicelo ze-hash kwimichiza kunye ne-petrochemical industry.As iivalvu zangaphambili kakuhle kule nkonzo kwaye kwacetyiswa ukuba zisetyenziswe kwezinye izicelo ze-hash kwikhemikhali kunye ne-petrochemical. ishishini.Ukucacisa ukuba kutheni i-valve ibe yimpumelelo singezantsi sichaze iimpawu zoyilo lwevalve ukubonelela ngaphakathi ngaphakathi kumandla ayo.
UMGAQO WOKUVULA NOKUVALWA KWEIvalve yeplagi yeDbb
Ukuvalwa kwevalve:
- 1) Jika intambo yokubamba nge-90 degree ukwenza umjelo weplagi ume nkqo kumjelo womzimba wevalvu
- 2) emva koko ujike ivili lesandla ukuhla iplagi, ukuze ivalve ivalwe.
Iimpawu eziphambili ze-Dbb plug valve
Iimpawu kunye neenzuzo zePhakamisa iValve yePlug.
- *Imveliso inesakhiwo esifanelekileyo, ukutywinwa okuthembekileyo, ukusebenza okugqwesileyo kunye nenkangeleko entle.
- * Iyakwazi ukusetyenziswa ngaphakathiiimeko zenkonzo ukuya kuthi ga650°C .
- *Isithintelo soomatshini kabini, ibhlokhi ephindwe kabini kunye neenketho zokopha.
- *Isihlalo sentsimbi ukuya kwintsimbi, ixesha elide lokuhlala, izihlalo ezikhuselweyo ekuphumeni ngokuthe ngqo kwindawo evulekileyo nevaliweyo.
- *Isihlalo esinobuso obunzima (i-stellite) sinokukhetha ukwenza okongeziweyo.
- *Akukho kuthambisa!Akukho kungcoliseka kwendlela yenkqubo.
- *Izixhobo zamalungu kunye nobukhulu beeflange zinokucwangciswa ngokufanelekileyo ngokweyona meko yokusebenza kweemfuno zabathengi, ukuze kuhlangatyezwane neemfuno ezahlukeneyo zobunjineli.
