Umehluko phakathi kwe-valve yesango le-stem elikhuphukayo kanye ne-valve yesango le-stem elikhuphukayo

A i-valve yesangoisetshenziselwa ukuxhumeka okuphakathi nendawo nokuvala, kodwa hhayi ukulawula.Uma kuqhathaniswa namanye ama-valve, ama-valve esango anohlu olubanzi lwezinhlelo zokusebenza ezihlangene mayelana nokucindezela, amafutha okusebenza, ingcindezi yokuklama kanye nezinga lokushisa.

Ngokusho kokuma kwentambo ye-valve stem, ii-valve yesangoingahlukaniswa i-valve yesango ye-stem ekhuphukayo kanye ne-valve yesango ye-stem engaphumi (NRS).

Umehluko omkhulu phakathi kwe-valve yesango le-stem elikhuphukayo kanye ne-valve yesango ye-stem engakhuphuki ngezansi:

1. Isiqu sesiqu esikhuphukayoi-valve yesangoobala futhi uyabonakala.

Isiqu se-valve yesango elingaphumi sisemzimbeni wevalvu futhi asikwazi ukubonakala;

2. I-Rising stem gate valvu ishayelwa intambo ye-valve stem kanye nesondo lokuqondisa, ngaleyo ndlela iqhubekisela i-Wedge ukuthi ikhuphuke futhi iwe;

I-valve yesango le-stem engavuki ishayela inkaba ukuthi ikhuphuke futhi iwe ngokujikeleza kwesiqu endaweni engashintshi.Lapho ushintsha, isondo lokuqondisa kanye nesiqu se-valve kuxhunywe ndawonye futhi kumile.

3. Intambo yokudlulisela ye-valve yesango enesiqu esingakhuphuki itholakala ngaphakathi komzimba we-valve.Phakathi nenqubo yokuvula nokuvala i-valve, isiqu sijikeleza kuphela endaweni, futhi isimo sokuvula nokuvala se-valve asikwazi ukuhlulelwa ngamehlo;

Intambo yokushayela esiqwini se-valve yesango ye-stem ekhuphukayo ivezwa ngaphandle komzimba we-valve, futhi ukuvuleka nokuvala kanye nendawo ye-wedge kungahlulelwa ngokunembile;

4. Ukuphakama kwe-valve yesango le-stem engakhuphuki kuncane, futhi indawo yokufaka incane;

I-valve yesango ye-stem ekhuphukayo inokuphakama okukhulu uma ivuliwe ngokugcwele, futhi idinga indawo enkulu yokufaka;

5. Isiqu se-valve yesango le-stem ekhuphukayo singaphandle komzimba we-valve, olungele ukulungiswa nokugcotshwa;

Intambo ye-stem ye-valve yesango ye-stem engavuki ingaphakathi komzimba we-valve, okunzima ukuyigcina nokugcoba, futhi isiqu se-valve siguguleka kalula yi-medium, futhi i-valve yonakaliswa kalula.

6. I-stem nut ye-valve yesango ye-stem ekhuphukayo ikubhonethi noma kubakaki.Lapho uvula futhi uvala isango, i-stem nut ijikeleziswa ukuze ifinyelele ekuphakamiseni noma ukwehlisa isiqu.

I-stem nut ye-valve yesango ye-stem engavuki isemzimbeni we-valve futhi ixhumene ngqo nendawo.Lapho uvula futhi uvala i-valve, ifinyelelwa ngokuzungeza isiqu se-valve.

7. Ukwakheka kwe-valve yesango le-stem ekhuphukayo kunenzuzo ekugcobeni kwesiqu, futhi izinga lokuvula nokuvala liyabonakala, ngakho-ke lisetshenziswa kabanzi.

Ukuphakama kwe-valve yesango le-stem engakhuphuki kuhlala kufana, ngakho-ke indawo yokufaka incane, futhi ifanele ama-valve esango anama-diameter amakhulu noma indawo yokufaka elinganiselwe.Lesi sakhiwo kufanele sifakwe inkomba yokuvula nokuvala ukukhombisa izinga lokuvula nokuvala.
