Yintoni indima yevalve yemoto yokutywina
Indima ephambili yokutywinwa kwevalve yemoto kukuqinisekisa ulungelelwaniso olusondeleyo phakathi kwevalve kunye nesitulo sevalvu ukuthintela ukuvuza kwegesi, ukuze kuqinisekiswe ukusebenza okuqhelekileyo kunye nokusebenza kwenjini. ...
Iivalve ezingavalwanga kakuhle zinokubangela iingxaki ezahlukeneyo, kuquka:
Ukuthotywa komgangatho wokusebenza: ukutywinwa kwevalve engalunganga kuya kukhokelela ekuvuzeni komoya, kuchaphazele ukusebenza okuqhelekileyo kwe-injini, kwaye emva koko kuncitshiswe ukusebenza ngokupheleleyo kwesithuthi.
Ukungaphumeleli koomatshini: ukutywinwa kwexesha elide kunokukhokelela ekwandeni kokunxitywa kwevalvu kunye nesitulo sevalvu, kwaye kude kukhokhelele ekungaphumelelini okukhulu koomatshini.
Ukonyuka kokusetyenziswa kwepetroli: ukuvuza komoya kuya kukhokelela ekutshisweni okungagqibekanga, ukonyusa ukusetyenziswa kwepetroli, ukunciphisa uqoqosho lwamafutha.
Ingxaki yokukhupha izinto ezikhutshwayo : Itywina eliyekelelayo linokuchaphazela ulawulo lokukhutshwa kwezinto ezikhutshwayo kwaye kunokubangela ukuba izinto ezikhutshwayo zibe ngaphezulu.
Ukuqinisekisa ukuqina kwevalve, la manyathelo alandelayo anokuthathwa:
Ukusetyenziswa kwezixhobo ezikumgangatho ophezulu kunye netekhnoloji yokuchaneka komatshini: izixhobo zevalve ezikumgangatho ophezulu kunye netekhnoloji yokucoca echanekileyo inokunciphisa umsantsa phakathi kwevalve kunye nesitulo sevalve, ukuphucula ukutywinwa.
Ukugcinwa rhoqo kunye nokutshintshwa kweendawo ezigugileyo : Ukutshintshwa kwangethuba kwezitywina zeoyile ezigugileyo kunye nezinye izitywini ukuthintela i-oyile ukuba ingangeni kwigumbi levalvu, okuchaphazela isiphumo sokutywinwa kwevalve.
ufakelo oluchanekileyo kunye nohlengahlengiso : Ukuqinisekisa ukuba intwasahlobo yevalve entwasahlobo iphakathi kunye nofakelo oluchanekileyo, ukuphepha ngenxa yokungonelanga kwentwasahlobo yasentwasahlobo okanye ukufakwa okungafanelekanga okubangelwa kukuvalwa okuyekelelayo.
Ukutywinwa kwevalve yemoto kubhekiselele kubuchule bevalve ukugcina ulwelo oluphakathi lungaphumi xa luvaliwe. Izitywina zeValve zinokwahlulwa ngokwemilo kunye nendawo yokutywinwa komphezulu kunye nesalathiso sokuhamba okuphakathi, ikakhulu zohlulwe kwezi ntlobo zilandelayo:
Isitywina seMetal : Ukusetyenziswa kokuguqulwa komatshini kunye nokuguqulwa kweplastiki phakathi kweendawo zetsimbi ukutywina ivalve, ilungele ubushushu obuphezulu kunye nezihlandlo zoxinzelelo oluphezulu.
isitywina esithambileyo: Ukusetyenziswa kwezixhobo zokugquma, irabha, iplastiki kunye nezinye izinto ezibhetyebhetye njengezixhobo zokutywina, ezilungele ukusetyenziswa koxinzelelo oluphantsi, njengeshishini lemichiza kunye neshishini lezonyango.
Sleeve seal : Isitywina esinomatshini, esilungele ubushushu obuphezulu kunye noxinzelelo okanye ngemithombo yeendaba eyonakalisayo.
Uvavanyo lokusebenza lokutywinwa kweValve
Ukuze kuqinisekiswe ukusebenza kokutywinwa kwevalve, iimvavanyo ezihambelanayo kufuneka zenziwe, ngakumbi kubandakanya:
Uvavanyo lokuqina komoya : Jonga ukuba kukho ukuvuza ngokuzalisa uxinzelelo oluthile lwegesi kwivalve.
Uvavanyo lokuqina kolwelo : Gcwalisa ivalve ngoxinzelelo oluthile lolwelo ukujonga ukuba kukho ukuvuza kunye nomgangatho wokutywina wevalve.
Uvavanyo lwamandla : jonga amandla acinezelayo kunye nomthamo wokuthwala wevalve ukuqinisekisa ukuba ayisayi konakaliswa ziingxaki zezinto eziphathekayo.
Uphuhliso lwetekhnoloji yokutywinwa kweValve
Itekhnoloji yokutywinwa kweValve ikakhulu ibandakanya ukutywinwa kwesitulo kunye nokutywinwa kwediskhi iindawo ezimbini. Kwiminyaka yakutshanje, kunye nenkqubela phambili yesayensi yezinto, iteknoloji yokucubungula kunye nengcamango yoyilo, iteknoloji yokutywinwa kwevalve yenze inkqubela ephawulekayo. Ukusetyenziswa kwezinto ezintsha zokutywina ezifana ne-polytetrafluoroethylene (PTFE), i-polyurethane, i-polyformaldehyde kunye nezinye izinto ze-polymer, kunye nokulungiswa koyilo lwesakhiwo sokutywinwa kunye nokusetyenziswa kobuchwephesha bokulawula obukrelekrele, kwenza ukuba ukusebenza kokutywinwa kwevalve kuphuculwe kakhulu.
