Isiqu esimnyama esilastiki sokutywina ivalve yesango: isixhobo esiyimfihlo solawulo lolwelo lwamashishini
Ngophuhliso olukhawulezayo lweshishini lanamhlanje, imfuno yeenkqubo zokulawula ulwelo iyanda imihla ngemihla. Kulo mxholo, kuye kwavela iivalvu ezahlukeneyo, kwaye enye yezona ndima zibalulekileyo "yi-non rise stem elastic seat etywiniweyo ivelufa yesango". Ke, yintoni ivalve yesango enganyukiyo isikhondo esilastiki esitywiniweyo? Ziziphi iimpawu neengenelo zayo?
1. Yintoni isikhondo esinganyukiyo esinelastiki sesitulo esitywiniweyo sesango?
Ivalve yesango efihliweyo sisixhobo esisetyenziselwa ukunqumla okanye ukulawula ukuhamba kolwelo. Xa kuthelekiswa neevalve zestem ezivulekileyo zemveli, eyona nto inkulu kukusetyenziswa koyilo lwesiqu esifihliweyo, ukwenza ukufakela kube lula kunye nokunciphisa umngcipheko womonakalo obangelwa zizinto zangaphandle.
2. Iimpawu eziphambili kunye neenzuzo
-Umsebenzi wokutywina owomeleleyo: Ngenxa yoyilo olukhethekileyo lwesitulo se-elastic, inokuqinisekisa isiphumo esihle sokutywinwa naphantsi koxinzelelo oluphezulu.
-Ubomi benkonzo ende: Yenziwe ngezinto ezikumgangatho ophezulu kwaye iphathwe ngokukodwa, inokumelana nokugqwala okungcono kunye nokumelana nokunxiba.
-Ukugcinwa okulula: Isakhiwo silula, kulula ukusichitha kunye nokugcina, ukunciphisa kakhulu iindleko zokugcinwa kunye nexesha.
-Ukuguquguquka okunamandla: ilungele imidiya eyahlukeneyo kunye neemeko zobushushu, nokuba ngamanzi abandayo, amanzi ashushu, okanye ulwelo lwekhemikhali, inokuphathwa ngokulula.
3. Indawo yesicelo
Isiqu esimnyama esilastiki sesitulo esitywiniweyo iivalvu zesango zisetyenziswa kakhulu kumashishini afana nepetroleum, iikhemikhali, isinyithi, amandla, kunye nokwakha, kwaye ziyinxalenye eyimfuneko kwiinkqubo zolawulo lwale mihla zolwelo.
Isiphelo:
Kwibala lanamhlanje lemizi-mveliso, isitulo esifihliweyo se-elastiki esitywinwe iivalvu zesango siphumelele inkoliseko yenani elikhulu labasebenzisi ngokusebenza kwabo okugqwesileyo kunye nomgangatho othembekileyo. Ukukhetha i-valve efanelekileyo ayinakuphucula kuphela ukusebenza kakuhle kwemveliso, kodwa nokugcina kakhulu iindleko zokusebenza. Ke ngoko, kubalulekile kwishishini ngalinye lemizi-mveliso ukuba liqonde kwaye likhethe ngokuchanekileyo kwaye lisebenzise izitulo ezinganyukiyo ezilastiki ezitywiniweyo zesango.
