Umehluko phakathi kwama-valve esango le-stem akhuphukayo kanye nama-valve esango le-stem angaphumi

I-valve yesango ingahlukaniswa:

1, i-stem gate valve: i-stem nut kukhava ye-valve noma ubakaki, vula futhi uvale isango, nge-rotary stem nut ukuze ufinyelele ukuphakama nokuwa kwesiqu.Lesi sakhiwo sinenzuzo ekugcobeni kwesiqu, futhi izinga lokuvula nokuvala liyabonakala, ngakho-ke lisetshenziswa kabanzi.

2, i-valve yesango elimnyama: i-stem nut emzimbeni we-valve, ukuthintana okuqondile nendawo.Vula futhi uvale isango ngokuzungezisa isiqu.Izinzuzo zalesi sakhiwo yilezi: ukuphakama kwe-valve yesango kuhlala kufana, ngakho-ke indawo yokufaka incane, ifanele ububanzi obukhulu noma ikhawulelwe endaweni yokufaka i-valve yesango.Isakhiwo kufanele sifakwe inkomba yokuvula nokuvala ukukhombisa idigri yokuvula nokuvala.Ukungalungi kwalesi sakhiwo ukuthi intambo ye-stem ayikwazi ukugcotshwa kuphela, kodwa futhi yamukele ngokuqondile ukuguguleka okuphakathi, ukulimaza kalula.

Umehluko omkhulu phakathi kwama-valve esango le-stem akhuphukayo nama-valve esango le-stem angaphumi:

1. Isikulufu esiphakamisayo se-valve yesango le-flange yesiqu esimnyama sizungeza kuphela futhi siye phansi, futhi okuveziwe kuyinduku kuphela.I-nati igxilile epuleti lesango, futhi isikulufu siyazungeziswa ukuze siphakamise ipuleti lesango, ngaphandle kohlaka olubonakalayo;Isikulufu esiphakamisayo se-valve yesango le-flange yesiqu esikhuphukayo sisobala, inathi liseduze nesondo lesandla futhi ligxilile (alizungezi noma alihambisani ne-axial), ngokuzungezisa isikulufu ukuze siphakamise isango, isikulufu nesango kunokunyakaza okuhambisanayo kuphela. ngaphandle kwe-axial displacement ehlobene, ukubukeka kubakaki bephothali.

2, i-valve yenduku emnyama ayikwazi ukubona isikulufu sokuhola, futhi induku ekhuphukayo ingabona isikulufu sokuhola.

3. Isondo lokuqondisa kanye nesiqu se-valve kuxhunywe ngendlela emile uma ivalvu ivuliwe futhi ivaliwe.Ivulwa futhi ivalwe ngokuzungezisa isiqu se-valve endaweni engaguquki ukushayela idiski phezulu naphansi kwebhuleki.Ama-valve e-stem akhuphukayo afakwa phakathi kwe-stem kanye nesondo lokuqondisa ukuphakamisa noma ukwehlisa idiski.Ukukubeka kalula, i-valve ye-stem ekhuphukayo iyidiski ehamba phezulu naphansi nesiqu, nesondo lokuqondisa lihlezi endaweni ngaso sonke isikhathi.
