Ivalve yentsimbi ehleli iplagi ethanjiswayo Ivalve yeplagi ethambisayo Umthengisi wemveliso wase China
Yintoni ivalve yeplagi ehleli ngentsimbi?
Ivalve yeplagi ehleli ngentsimbi iqulathe umngxuma kumbindi weplagi ecaleni kweaxis yayo.Lo mgodi uvalwe ezantsi kwaye ufakwe isitofu se-sealant-injection phezulu.I-sealant ifakwe kwi-cavity, kwaye ivalve yokutshekisha engaphantsi kwesitofu esifanelekileyo sithintela isitywina ukuba singagelezi kwicala elingasemva.Isitywina siphuma kumbindi womngxuma siphumela kwimingxuma emitha yemitha ukuya kwigrooves yezithambiso ezithi zinyukele kubude bomphezulu wokuhlala weplagi.
Ukuze kuncitshiswe i-torque yesitulo sentsimbi eqhelekileyo, iivalvu zeplagi ezithanjiswayo,Ivalve yeplagi ehleli ngentsimbiziyilwa kwaye zisetyenziswa ngokubanzi.Ukongeza kwiimpawu ze-oyile yesiqhelo yeevalvu zeplagi, i-valve yeplagi elungelelanisiweyo yoxinzelelo nayo inezi mpawu zilandelayo:
- 1. Xa ivalve ivulwa, uxinzelelo olukwigumbi elisezantsi lomzimba wevalve lilingana noxinzelelo oluphakathi kumbhobho.Ioyile yokutywina yoxinzelelo oluphezulu kwigumbi eliphezulu ibangela ukuba umzimba weplagi utyhalelwe ezantsi, kwaye kubonakale umsantsa omncinci phakathi kwekhowuni yeplagi kunye nomgangatho wokutywina womzimba wevalve, itorque yomzimba weplagi ejikelezayo iyancitshiswa ngempumelelo.
- 2. Kwiimeko eziphezulu zeqondo lokushisa, ukwandiswa kwe-thermal yeplagi kunokuthatyathwa ngokunyuka nokuwa kwayo.I-oil lubricated plug valve, nangona ukusetyenziswa kwe-oyile yokuthambisa kunokunciphisa ngokufanelekileyo i-torque yokuvula kunye nokuvala, kodwa inokwenza ungcoliseko oluphakathi.Ngoko ke, i-lubricant etywiniweyo ikhethwa kwiimeko zangempela zokusebenza.
Iimpawu eziphambili zentsimbi ehleli ivelufa yeplagi
Iimpawu kunye neenzuzo zeIvalve yeplagi ehleli ngentsimbi
- I-1.Imveliso inesakhiwo esifanelekileyo, ukutywinwa okuthembekileyo, ukusebenza kakuhle kunye nokubonakala okuhle.
- I-2.Inokwakheka koxinzelelo lwe-flip-clip elinganiselayo kunye nokukhanya kokuvula / ukucima ukusebenza.
- 3.Izixhobo zamalungu kunye nobukhulu beeflange zinokucwangciswa ngokufanelekileyo ngokweyona meko yokusebenza kweemfuno zabathengi, ukuze kuhlangatyezwane neemfuno ezahlukeneyo zobunjineli.
