Ngokwahlukileyo, nangona i-valve yokukhupha i-valve ehlayo inesakhiwo esiyinkimbinkimbi, inoluhlu olubanzi lwezicelo, iimfuno eziphantsi zezinto eziphathekayo, kwaye ingaba nobomi obude benkonzo kunye neendleko zokugcina eziphantsi.
Umthamo kunye nokusebenza kakuhle: I-valve yokukhupha i-valve ezantsi ilawula isantya sokuhamba kwezinto ngokuchanekileyo, enokulawula ngcono umgangatho wemveliso kunye nokuphucula ukusebenza kakuhle kwemveliso. Ivalve yokukhupha iphezulu inokuchaphazela umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso ngenxa yemicimbi eshiyekileyo. Ngoko ke, ngokubhekiselele kumandla okuvelisa kunye nokusebenza kakuhle, i-valve yokukhupha i-valve ehlayo inokuba nempumelelo ephezulu yezoqoqosho.
3. Uvandlakanyo lokuthembeka
Ukuzinza kokusebenza: I-valve yokukhupha i-expansion upward ilula ukusebenza kwaye inophawu lokuzicoca, ukunciphisa inani kunye nokuphindaphinda kokucoca, ngaloo ndlela kuphuculwe ukuzinza kokusebenza. Nangona i-valve yokukhupha isandisi esisezantsi sinesakhiwo esiyinkimbinkimbi, xa sele ifakwe kwaye ihlanjululwe ngokuchanekileyo, isenokubonelela ngokusebenza okuzinzileyo.
Izinga lokungaphumeleli kunye nomjikelo wokulondoloza: Ngenxa yesakhiwo sayo esilula, iivalve ezikhupha phezulu zihlala zinezinga eliphantsi lokungaphumeleli. Nangona kunjalo, ngenxa yokunciphisa umda wokusetyenziswa kwayo, ukulungiswa rhoqo kunye nokuhlolwa kunokufuneka. Nangona i-valve yokukhupha i-valve ehlayo inesakhiwo esiyinkimbinkimbi, ngenxa yokusetyenziswa kwayo okuphezulu kunye nokuzinza, ingaba nomjikelezo omde wokulondoloza kunye nezinga lokungaphumeleli eliphantsi.
4, Uhlalutyo olubanzi lweendleko-inzuzo
Ukuthathela ingqalelo izinto zombini kunye nokuthembeka, i-valve yokukhupha i-valve ephezulu kunye nesezantsi, nganye ineenzuzo kunye nokungona kwayo. Ivalve yokukhupha i-expansion expansion iqhuba kakuhle ngokweendleko zotyalo-mali lokuqala kunye nokuzinza kokusebenza, kodwa inokunyusa iindleko zokusebenza ngenxa yokulinganiselwa ekusebenzeni kwayo. Nangona ixabiso lokuqala lotyalo-mali lwe-valve yokukhupha i-valve ehlayo iphezulu kakhulu, uluhlu olubanzi lwesicelo kunye nokusebenza okuzinzileyo kunokuzisa iindleko eziphantsi zokusebenza kunye nokugcinwa kwexesha elide.
Ke ngoko, xa kukhethwa iivalvu zokukhupha ezandisiweyo ezinyukayo nasezantsi, amashishini kufuneka aqwalasele ngokubanzi izinto ezinjengeemfuno zabo zemveliso, iimpawu zemathiriyeli kunye nohlahlo lwabiwo-mali. Kwizicelo ezinoluhlu oluncinci lwe-viscosity kunye neemfuno eziphezulu ze-particle, i-valve yokukhupha i-valve yokwandisa inokuthi ifaneleke ngakumbi; Kwiimeko ezifuna ukusetyenziswa okubanzi, ukuthembeka okuphezulu, kunye nolawulo oluchanekileyo, i-valve yokukhupha i-valve ehlayo ingaba neenzuzo ezininzi.
5. Isiphelo
Ngokuphonononga uqoqosho kunye nokuthembeka kwe-valve yokukhupha i-up and down expansion, sinokubona ukuba nganye ineenzuzo zayo ngokubhekiselele kwindleko-esebenzayo. Amashishini kufuneka avavanye ukhetho lwawo ngokusekelwe kwiimeko zokwenyani ukuze afumane imbuyekezo yotyalo-mali eyiyeyona ilungileyo kunye nokusebenza kakuhle. Ngeli xesha, ngenkqubela phambili eqhubekayo yetekhnoloji kunye notshintsho kwimarike, kunokubakho iintlobo ezintsha zeemveliso zevalve yokukhupha eziphuma kwixesha elizayo. Amashishini kufuneka agcine ingqwalasela yawo kubuchwephesha obutsha kunye neemveliso ukuze abambe amathuba entengiso kwangexesha.
