I-Valve yeSango leNtsimbi engaGciniyo

I-Valve yeSango leNtsimbi engaGciniyo

Inxalenye yokuvula nokuvala yevalvu yesango lentsimbi engagqwaliyo yisango, kwaye indlela yokuhamba kwesango ihambelana ngqo necala lolwelo. Isango lentsimbi engagqwaliyo lineendawo ezimbini zokutywina. Iindawo ezimbini zokutywina zevalvu yesango yemodeli esetyenziswa kakhulu zenza i-wedge, kwaye i-wedge angle iyahluka ngokweeparamitha zevalvu. Isango levalvu yesango le-wedge lingenziwa libe yinto epheleleyo, ebizwa ngokuba yi-rigid gate; lingenziwa libe yisango elinokuvelisa ukuguquguquka okuncinci ukuphucula ukwenziwa kwalo kunye nokubuyisela ukuphambuka kwe-angle yomphezulu wokutywina ngexesha lokucubungula. Ipleyiti ibizwa ngokuba yi-elastic gate. Izixhobo zevalvu yesango lentsimbi engagqwaliyo zahlulwe zaba yi-CF8, CF8M, CF3, CF3M, 904L, Duplex Stainless Steel (4A, 5A, 6A).

Iintlobo zeeValve zeSango leNtsimbi engaGciniyo

Ingahlulwa ibe ziivalvu zesango le-wedge kunye neevalvu zesango ezihambelanayo ngokwesimo somphezulu wokutywina.

Iivalvu zesango le-Wedgeinokwahlulwahlulwa ibe:

• Uhlobo lwesango elinye
• Uhlobo lwesango eliphindwe kabini
• Uhlobo lwesango le-elastic

Ivalvu yeSango lePrallelIngohlulwa ibe

• Uhlobo lwesango elinye
• Uhlobo lwesango eliphindwe kabini

Yahlulwe ngokwendawo yomsonto wesiqu sevalvu

Ingohlulwa ibe ziintlobo ezimbini:

• Ivalvu yesango lesiqu esinyukayo
• Ivalvu yesango lesiqu esinganyukiyo.

Ivalvu yesango lentsimbi engagqwaliyo kufuneka ifakwe ngokuthe tye kwipayipi.Xa ivalvu ivuliwe, xa ukuphakama kwesango kufana ne-1:1 ngokuphindwe ubukhulu bevalvu, indlela yolwelo ivuliwe ngokupheleleyo, kodwa le ndawo ayinakujongwa ngexesha lokusebenza.

Xa isetyenziswa ngokwenene, incopho yesiqu sevalvu isetyenziswa njengophawu, oko kukuthi, indawo apho ingenakuvulwa khona, njengendawo yayo evulekileyo ngokupheleleyo. Ukuze kuqwalaselwe into yokutshixa ngenxa yotshintsho lobushushu, ivalvu idla ngokuvulelwa kwindawo yencopho ize ibuyiselwe umva nge-1/2 ukuya kwi-1 turn njengendawo yevalvu evuleke ngokupheleleyo. Ke ngoko, indawo evuleke ngokupheleleyo yevalvu imiselwa yindawo yesango (oko kukuthi i-stroke).

Kwezinye iivalvu zesango, i-stem nut ibekwa esangweni, kwaye ukujikeleza kwevili lesandla kuqhuba ukujikeleza kwe-valve stem ukuze kuphakanyiswe isango. Olu hlobo lwevalvu lubizwa ngokuba yi-rotary stem gate valve okanye i-non-rising stem gate valve.
