Ivalve yeplagi yokuphakamisa iplagi yaseTshayina umniki-mveliso waseTshayina uMvelisi
Yintoni ivalve yeplagi yokunyusa?
Intsimbi engathanjiswanga ihleliivalve yeplagi yokuphakamisazaphuhliswa 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 yokuphakamisa
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.
Ngexesha lokuvula kunye nokuvalwa kwevalve, iplagi iyaphakanyiswa kwaye yahlulwe kwisihlalo sevalve, ngoko ke i-torque yokusebenza incinci kakhulu, kulula kakhulu ukuyivula nokuvala ivalve.Kwaye ubuso bokutywinwa bubungqina obukhatywayo ngexesha lokuvula okanye inkqubo yokuvala.Ngoko ivalve inobomi obude.I-handwheel handle yokuphakamisa uhlobo lwe-valve yeplagi inesakhiwo esihlangeneyo, umthamo omncinci kunye nokumelana nolwelo oluphantsi.
Iimpawu eziphambili zokuphakamisa i-valve yeplagi
Iimpawu kunye neenzuzo zeivalve yeplagi yokuphakamisa.
- *Imveliso inesakhiwo esifanelekileyo, ukutywinwa okuthembekileyo, ukusebenza okugqwesileyo kunye nenkangeleko entle.
- *Uyilo oluphezulu lokungena, ukugcinwa lula.
- *Umsebenzi wamacala amabini, uyilo olukhuselekileyo emlilweni.
- *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.

Qaphela: ubungakanani be-serial valve yokudibanisa i-flange inokuqulunqwa ngokweemfuno zabathengi.
Ukusetyenziswa kwevalve yeplagi yokuphakamisa
ivalve yeplagi yokuphakamisaisetyenziswa kakhulu kwiimeko ezinzima zokusebenza,
- *Iimveliso zekhemikhali / zepetrochemical (izicelo zokukrazula)
- *ulwelo oluyikristale
- *ulwelo lwe-viscosity ephezulu
- *ulwelo lwecryogenic
- *iiasidi / isiseko / imimoya enobundlobongela
- *iigesi ezineziqina
