Umahluko phakathi kweevalvu zesango lesiqu esinyukayo kunye neevalvu zesango lesiqu esingaphumiyo

Ivalve yesango inokwahlulwa ibe:

1, ivalve yesango lokunyuka: i-stem nut kwisigqubuthelo sevalve okanye isibiyeli, vula kwaye uvale isango, nge-rotary stem nut ukuphumeza ukunyuka nokuwa kwesiqu.Esi sakhiwo sinenzuzo kwi-lubrication ye-stem, kwaye iqondo lokuvula kunye nokuvala licacile, ngoko lisetyenziswa ngokubanzi.

I-2, ivalve yesango elimnyama: i-stem nut kumzimba wevalve, ukudibana ngokuthe ngqo nendawo.Vula kwaye uvale isango ngokujikeleza isiqu.Iingenelo zesi sakhiwo kukuba: ukuphakama kwevalve yesango kuhlala kufana, ngoko ke indawo yokufakela incinci, ifanelekile ububanzi obukhulu okanye inqunyelwe kwindawo yokufakela i-valve yesango.Isakhiwo siya kuxhotyiswa ngesalathisi sokuvula kunye nokuvala ukubonisa idigri yokuvula nokuvala.Ukungalungi kwesi sakhiwo kukuba intambo ye-stem ayinakuthanjiswa kuphela, kodwa ikwamkele ngokuthe ngqo ukukhukuliseka okuphakathi, kulula ukuyonakalisa.

Umahluko ophambili phakathi kweevalvu zesango lesiqu esinyukayo kunye neevalvu zesango lesiqu esingaphumiyo:

1. I-screw yokuphakamisa i-valve yesango ye-flange emnyama ijikeleza kuphela kwaye ihla, kwaye ibonakaliswe yintonga kuphela.I-nut igxininiswe kwiplani yesango, kwaye i-screw ijikelezwe ukuphakamisa iplate yesango, ngaphandle kwesakhelo esibonakalayo;I-screw yokunyusa i-valve yesango le-flange ye-stem ephakamayo ibonakalisiwe, i-nut isondele kwi-handwheel kwaye igxininiswe (ingekho ukujikeleza okanye intshukumo ye-axial), ngokujikelezisa isikrufu ukuphakamisa isango, isikrufu kunye nesango zinentshukumo ejikelezayo kuphela. ngaphandle kokufuduswa kwe-axial, ukubonakala sisibiyeli se-portal.

I-2, ivalve yentonga emnyama ayiboni isikrufu sokukhokela, kwaye intonga ekhulayo inokubona isikrufu sokukhokela.

3. Ivili lokuqhuba kunye nesiqu sevalve ziqhagamshelwe ngokuzinzileyo xa ivalve ivuliwe kwaye icinyiwe.Ivulwa kwaye ivalwe ngokujikelezisa isiqu sevalve kwindawo esisigxina ukuqhubela idiski phezulu nasezantsi kwebhuleki.Iivalve zesikhondo ezinyukayo zifakwe phakathi kwesiqu kunye nevili lokuqhuba ukunyusa okanye ukuthoba idiski.Ukuyibeka ngokulula, ivalve yesikhondo esinyukayo yidiski ehamba phezulu nasezantsi kunye nesiqu, kunye nevili lokuqhuba lisendaweni ngalo lonke ixesha.
