Iintlobo kunye nemisebenzi yeevalvu zekhemikhali
Vula kwaye uvale uhlobo: ukunqumla okanye ukunxibelelana ngokuhamba kolwelo kumbhobho;uhlobo lommiselo: lungisa ukuhamba kunye nesantya sombhobho;
Uhlobo lwe-Throttle: yenza ulwelo luvelise ukuhla koxinzelelo olukhulu emva kokudlula kwivalve;
Ezinye iintlobo: a.Ukuvula nokuvalwa okuzenzekelayo b.Ukugcina uxinzelelo oluthile c.Ukuthintela umphunga kunye nokukhupha amanzi.
Imigaqo yokukhetha i-valve yekhemikhali
Okokuqala, kufuneka uqonde ukusebenza kwevalve.Okwesibini, kufuneka uqonde amanyathelo kunye nesiseko sokukhetha ivalve.Okokugqibela, kufuneka ulandele imigaqo yokukhetha iivalvu kumashishini epetroleum kunye neekhemikhali.
Iivalvu zekhemikhali ngokuqhelekileyo zisebenzisa imidiya ekulula ukuyikhuhla.Ukusuka kwishishini elilula le-chlor-alkali ukuya kwishishini elikhulu lepetrochemical, kukho iingxaki ezifana nobushushu obuphezulu, uxinzelelo oluphezulu, ukonakala, ukunxiba lula, kunye nobushushu obukhulu kunye nokwahluka koxinzelelo.Ivalve esetyenziswe ngolu hlobo lomngcipheko ophezulu kufuneka isetyenziswe ngokungqongqo ngokuhambelana nemigangatho yeekhemikhali ekukhetheni nasekusebenziseni inkqubo.
Kwishishini lemichiza, iivalve ezinemijelo ethe tye-ngokuhamba ngokuthe ngqo zikhethwa ngokuqhelekileyo, ezinokumelana nokuhamba okuphantsi.Ngokuqhelekileyo zisetyenziswa njengezivalo ezivaliweyo kunye nezivulekileyo eziphakathi.Iivalvu ekulula ukuhlengahlengisa ukuhamba kwazo zisetyenziselwa ukulawula ukuhamba.Iivalve zeplagi kunye neebhola zebhola zifaneleke ngakumbi ukubuyisela umva kunye nokwahlula., Ivalve enefuthe lokusula kwi-sliding yelungu elivalayo ecaleni kwendawo yokutywina ifaneleke kakhulu kwi-medium kunye namasuntswana amisiweyo.Iivalvu zeekhemikhali eziqhelekileyo ziquka iivalve zebhola, iivalve zesango, iivalve zeglowubhu, iivalvu zokhuseleko, iiplagi zeplagi, iivalve zokujonga njalo njalo.Ubuninzi bemidiya yevalvu yemichiza iqulethe izinto zekhemikhali, kwaye zininzi i-acid-base media corrosive.Isixhobo se-valve yekhemikhali yefektri yaseTaichen ikakhulu yi-304L kunye ne-316. Imidiya eqhelekileyo ikhetha i-304 njengento ehamba phambili.Ulwelo oludlekayo oludityaniswe nezinto ezininzi zeekhemikhali zenziwe ngentsimbi yealloyi okanye ivalve ene-Fluorine.
Izilumkiso phambi kokusebenzisa iivalvu zekhemikhali
① Nokuba kukho iziphene ezinje ngamadyungudyungu kunye neentanda kumphezulu wangaphakathi nangaphandle wevalvu;
②Ukuba isihlalo sevalve kunye nomzimba wevalvu zidityaniswe ngokuqinileyo, nokuba umbindi wevalve kunye nesitulo sevalvu ziyahambelana, nokuba umphezulu wokutywina uneziphene;
③Nokuba unxibelelwano phakathi kwesikhondo sevalve kunye nombindi wevalve lubhetyebhetye kwaye luthembekile, nokuba isiqu sevalve sigobile, kwaye nokuba umsonto wonakele.
