Ukudilizwa ngokudibeneyos idlala indima egqibeleleyo kuyilo kunye noyilo lwemibhobho kunye neevalvu.Ziyincedo oluyimfuneko ngexesha lofakelo kunye nokususwa kwamacandelo emibhobho kunye neevalve.Ngaphandle kokudilizwa okudityanisiweyo okudityanisiweyo uhlengahlengiso longitudinal, phantse akunakwenzeka ukufaka ivalve ngqo kwicandelo lombhobho.Ngombulelo kolu lungelelaniso lwejoyinti yokuqhawula, ivalve inokufakwa ecaleni kwejoyinti yokuqhawula, kwaye idibansi yokuqhawula inokubekwa kubude obuchanekileyo obufunekayo ngaphambi kokuba idityaniswe ngokukhuselekileyo kwiiflange.

Ulandelelwano lokubuyela umva lusetyenziselwa ukuqhawula, apho ukulungiswa kwakhona kobude bomdibaniso wokuqhawula kudala indawo eyaneleyo yokukhulula kunye nokususa ivalve.Kuzo zombini ezi meko, ukudilizwa okudityanisiweyo kuqinisekisa ukufakwa kunye nokususwa ngokukhawuleza, ngaloo ndlela kube negalelo ekwandeni kobuchule kunye nokunciphisa ukusebenza kwesiza kunye nexesha eliphantsi.Inkqubo iyafana apho amacandelo emibhobho kufuneka adityaniswe kunye.Iintlobo ezithile zokuqhawula amajoyina nazo zifanelekile ukusetyenziswa ngaphandle kokuthintela kwiipayipi eziguquguqukayo.Okokugqibela, amalungu okuqhaqha angasetyenziselwa ukuvala izikhewu umz. apho impompo efakwe kwindawo ezinzileyo kufuneka idityaniswe kumbhobho ophuma eludongeni.

Iinzuzo zokuqhawula ngokudibeneyo
I-1.Ukufakwa kulula kwaye kulula, ukufakwa kwe-valve efanelekileyo.
I-2.I-Rubber yomelele kwi-compression kunye ne-elasticity.
3.Iintsimbi kunye nezangqa zokutywina zingqongqo kakhulu.
4.Embhobho, inokuhlawula ngokufanelekileyo kunye nokunciphisa umbhobho kunye ne-blind plate thrust.
