Umgangatho oPhezulu woShishino oSoft isitulo seplagi ivelufa eLubricated plug valve Lubricated plug valve China factory Supplier Manufacturer
Yintoni ivalve yeplagi yesitulo esithambileyo?
Ivalve yeplagi yesitulo esithambileyo 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 yesitulo esithambileyoziyilwa 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 zevalve yeplagi yesitulo esithambileyo
Iimpawu kunye neenzuzo zeIvalve yeplagi yesitulo esithambileyo
- 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.Umjelo we-oyile usetwe phakathi komzimba wevalvu kunye nomphezulu wokutywina, onokufaka igrisi yokutywina ukwandisa isakhono sokutywina.
