Yintoni esifanele sinikele ingqalelo kuyo ngaphambi kokufaka i-valve butterfly?

Kwinkqubo yemibhobho yePVC yeshishini, uhlobo lomqheba lwevalve yebhabhathane luhlobo oluqhelekileyo. Ngenxa yokwakheka kwale valve yebhabhathane incinci ngokwentelekiso. Xa ufaka ivalve yebhabhathane embindini weflange kuzo zozibini iziphelo zombhobho, ngebhawudi enentloko-mbini kwiflange yombhobho ukutshixa ivalve yebhabhathane, enokulawula umbhobho wolwelo oluphakathi.

Ngenxa yokuba iivalve zebhabhathane zifanelekile kwiindawo ezinesithuba esimxinwa okanye umgama omfutshane phakathi kwemibhobho, xa ivalve yebhabhathane ikwimeko evulekileyo, ivalve yevalve yiyona ndlela yokumelana nokuhamba okuphakathi ngomzimba wevalve, ngoko ke uxinzelelo oluveliswa yivalve. incinci, kwaye kukho ulawulo olungcono lokuhamba kwe-medium. Oku kwenza umqheba wohlobo lwevalve yebhabhathane idume kakhulu kwimarike yombhobho weshishini, kodwa kukho amanqaku asixhenxe ekufuneka sinikele ingqalelo kuwo phambi kokufaka umqheba wohlobo lwevalve yebhabhathane.

1, Kodwa kukho iingongoma ezisixhenxe ekufuneka sinikele ingqalelo phambi kokufaka isibambo butterfly valve.

I-2, Ngaphambi kokufaka i-valve ye-butterfly, ngaphandle kombhobho kufuneka utshizwe ngomoya kwaye ingaphakathi lombhobho kufuneka lihlanjwe ngamanzi.

I-3, Kufuneka sihlolisise ngokucophelela ukuba ukusebenza kwe-valve ye-butterfly kunye nokusetyenziswa kwemeko iyahambelana, njengokushisa, uxinzelelo kunye nokunye.

I-4, Kufuneka sihlolisise indawo yokutywina yevalve yebhabhathane kunye nejelo levalve ngaphambi kokufakwa ukuze sibone ukuba kukho nayiphi na inkunkuma kwaye icoceke ngexesha.

Iivalve zebhabhathane kufuneka zifakwe ngaphandle kwebhokisi ngexesha elifanelekileyo, kwaye naziphi na izikrufu eziqinileyo okanye amandongomane kwivalve akufanele zikhululeke ngokuthanda.

5, Sebenzisa iiflange zevalve yebhabhathane ezikhethekileyo zohlobo lweevalvu zebhabhathane.

I-6, ivalve yebhabhathane yombane kuba inokufakwa kuyo nayiphi na i-engile yombhobho, ngoko ke ukuze kugcinwe ukulungelwa kwexesha elizayo, akukhuthazwa ukuba ufake ivalve yebhabhathane yombane ijonge phantsi.

I-7, xa ufaka i-flange ye-valve ye-butterfly, kufuneka siqinisekise ukuba i-flange surface kunye ne-rubber yokutywinwa igxininisekile, qinisa izikhonkwane zokulungisa, kwaye indawo yokutywina kufuneka ifaneleke kwaye iphelele: ukuba kukho amandla angalinganiyo okuqinisa izikhonkwane, izakukhokelela kwipleyiti yebhabhathane egcwele irabha okanye umphezulu wepleyiti yebhabhathane ibangele ukuvuza kwesikhondo sevalve.
