Ngenxa yokungqubana okuphantsi phakathi kweendawo zokutywina ngexesha lenkqubo yokuvula nokuvala, ivalvu yokuvala ihlala ixesha elide kwaye inokuphakama okuncinci kokuvula. Ayifanelekanga kuphela kuxinzelelo oluphakathi noluphantsi, kodwa ikwafanelekile nakwiindawo zoxinzelelo oluphezulu. Ngokuxhomekeke kuxinzelelo lwesiqu sevalvu, umphezulu wokutywina wediski kunye nomphezulu wokutywina wesihlalo sevalvu zinamathele kakhulu ukuthintela ukuba i-medium ingahambi, eyivalvu yokutywina enyanzelekileyo. Ukuze ivumelane nokusetyenziswa kwezihlandlo ezahlukeneyo, kukho iintlobo ezine zeevalvu zokuvala ezinemisebenzi eyahlukeneyo: ivalvu yokuvala i-plunger, ivalvu yokuvala ukuhamba ngqo, ivalvu yokuvala eqhelekileyo kunye nevalvu yokuvala i-angle. Yintoni umahluko phakathi kwazo?
1) Indawo yokungena kunye nendawo yokuphuma yevalvu yokumisa yohlobo lwe-angle zikwi-engile yama-90 degrees. Ivalvu yokumisa yohlobo lwe-angle idla ngokufakelwa kwikona yombhobho kwaye inokutshintsha indawo yombhobho odibeneyo kwikona.
Kwivalvu yokuvala yohlobo lwe-angle, ulwelo lufuna ukutshintsha icala lalo kube kanye kuphela, ukuze ukuhla koxinzelelo kwivalvu kube kuncinci kunokwevalvu yokuvala eqhelekileyo.
2) Iimpawu zesakhiwo kunye nezakhono zokukhetha ivalvu yokumisa ukuhamba ngqo, ivalvu yokumisa ukuhamba ngqo, ivalvu yokumisa i-angle kunye nevalvu ye-plunger ziivalvu zokumisa zohlobo lwe-Y. Nge-engile ye-45 degrees, inqanaba lomonakalo kwimeko yokuhamba lincinci kuneleevalvu zokuvala eziqhelekileyo, ngoko ke ukulahleka koxinzelelo ngevalvu nako kuncinci ngokufanayo. Kunokuthiwa akukho lahleko yokuhla koxinzelelo, kwaye ikwayeyona lahleko incinci yokuhla koxinzelelo kuzo zonke iivalvu zokuvala.
3) Ivalvu yeglobe yohlobo lwePlunger: Olu hlobo lwevalvu yeglobe luyinguqulelo yevalvu yeglobe eqhelekileyo. Kule valve, idiski kunye nesihlalo sevalve zihlala ziyilwa ngokusekelwe kumgaqo weplunger. I-clack yevalve iyapholishwa ukuze iplunger kunye nesiqu sevalve ziqhagamshelwe, kwaye ukutywinwa kufezekiswa ngeendandatho ezimbini ze-elastic sealing sleeves kwiplunger. Iindandatho ezimbini ze-elastic sealing zahlulwe yiringi yesleeves, kwaye iringi yokutywina ejikeleze iplunger icinezelwe ngokuqinileyo ngumthwalo osebenza kwibhonethi yi-bonnet nut. Iringi yokutywina ye-elastic inokutshintshwa kwaye ingenziwa ngezinto ezahlukeneyo. Ivalvu isetyenziselwa kakhulu "ukuvula" okanye "ukuvala", kodwa ixhotyiswe ngohlobo olukhethekileyo lweplunger okanye ikhola ekhethekileyo. Ivalvu yoxinzelelo lwesihlalo sevalve ephindwe kabini ibhalansi ethe tye. Iplunger inokunyuka nokuhla kwiindandatho zokutywina eziphezulu nezisezantsi kunye nesleeves zesikhokelo. Isleeves zesikhokelo zibonelelwa ngomngxuma wokulinganisela uxinzelelo, kwaye uxinzelelo oluphakathi lunokungena kumngxuma ongezantsi wesleeves zesikhokelo ngomngxuma omncinci. Ukutywina kunokufezekiswa ngomphezulu wokutywina kabini we-plunger kunye neringi yokutywina kabini emzimbeni we-valve, kwaye ukuhamba okukhulu kunokudluliswa. Ngenxa yokuba i-plunger imfutshane, isantya sokuvula nokuvala siphezulu kunese-valve ye-plunger eqhelekileyo; ibhalansi yoxinzelelo ethe tye-ngakwi-valve ye-plunger, I-plunger ayinanto, kwaye amagumbi aphezulu nasezantsi anemingxuma. Isiqu se-valve siqhagamshelwe kwisingxobo sokutywina esingaphezulu kunye ne-nut ukulinganisela uxinzelelo kumagumbi aphezulu nasezantsi e-plunger kunye nokonga umgudu xa uvula kwaye uvala. Nangona kunjalo, isiqu se-valve kufuneka sibe nesingxobo esingaphezulu kunye nesingxobo sokupakisha, kwaye isantya sokuvula nokuvala sicotha.
