Iimpazamo eziqhelekileyo kunye neendlela zokusombulula iingxaki zezivalo zebhola!

Iimpazamo eziqhelekileyo zezivalo zebhola kunye neendlela zokujongana nokusombulula iingxaki Iibhola zeebhola zinokuba nokuvuza kwangaphakathi ngexesha lokusetyenziswa okanye lofakelo. Ngenxa yokutshintsha rhoqo ngexesha lokusetyenziswa, okanye ukusilela ukufaka njengoko kufuneka, ivalve yebhola ayinakusebenza ngesiqhelo.

Izizathu zokuvuza kwangaphakathi kwevalvu yebhola zahlulwe zangamacandelo amabini: izizathu zokuvuza ngaphakathi kwevalve ngexesha lolwakhiwo:
Ukuhamba ngokungafanelekanga kunye nokuphakamisa ukuphakama kubangela umonakalo omkhulu kwivelufa kwaye kubangele ukuvuza kwangaphakathi kwevalve;
HenXa ushiya umzi-mveliso, ivelufa ayomiswanga kwaye ichase ukubola emva kokuba kufakwe uxinzelelo lwamanzi, ibangela ukuba indawo yokutywina iruse kwaye yenze ukuvuza ngaphakathi;
Ukhuselo lwesiza sokwakha alukho endaweni, akukho sitya singaboniyo sifakwe kuzo zombini iziphelo zevalve, kwaye ukungcola okunje ngamanzi emvula kunye nesanti kungena kwisitulo sevalve, kubangela ukuvuza;
UringNgexesha lofakelo, akukho greisi yayitofelwe kwisihlalo sevalve, esenza ukungcola kungene ngasemva kwesihlalo sevalve, okanye ukuvuza kwangaphakathi ngexesha lokudibanisa *;
ValveIvalve ayifakwanga kwindawo evulekileyo ngokupheleleyo, ibangela umonakalo kwibhola. Ngexesha le-welding, ukuba ivelufa ayikho endaweni evulekileyo ngokupheleleyo, i-welding spatter iya kwenza umonakalo kwibhola. Xa ibhola nge-welding spatter ivuliwe kwaye ivaliwe, iya kubangela umonakalo kwisitulo se-valve. , Okukhokelela ekuvuza ngaphakathi;
Imikrwelo kwindawo yokutywina ebangelwa yi-welding slag kunye nezinye izinto zokwakha;
Umda ongachanekanga ngexesha lokuhanjiswa okanye ukufakelwa kubangela ukuvuza. Ukuba umkhono we-valve stem drive okanye ezinye izincedisi zihanjiswe kakubi nge-angle angle, i-valve iya kuvuza.

Izizathu zokuvuza kwangaphakathi kwevalve ngexesha lokusebenza:
The * Isizathu esiqhelekileyo kukuba umphathi womsebenzi akayigcini ivelufa xa kuthathelwa ingqalelo iindleko zokulondolozwa okubiza kakhulu, okanye ukunqongophala kolawulo lwevalve kunye nezindlela zokugcina azenzi luthintelo kwivalve, ebangela ukuba isixhobo singasebenzi kakuhle phambili;
Umsebenzi ombi okanye ukusilela ukulandela iinkqubo zolondolozo ukugcina ukuvuza ngaphakathi;
Ngexesha lokusebenza okuqhelekileyo, izinto zokwakha zikrwela umphezulu wokutywina, ubangele ukuvuza ngaphakathi;
Iihagu ezingafanelekanga zibangela ukuvuza ngaphakathi ngenxa yomonakalo kumphezulu wokutywina;
Ukuba ivalve ayigcinwanga okanye ihanjiswe ixesha elide, isihlalo sevalve nebhola iya kutshixwa, kwaye itywina liya konakala xa ivalve ivuliwe kwaye ivaliwe, kwaye ukuvuza kwangaphakathi kuyakwenziwa;
Iswitshi yevelufa ayikho endaweni yokubangela ukuvuza ngaphakathi. Nayiphi na ivelufa yebhola, nokuba ivulekile okanye ivaliwe, ihlala ithambile 2 ° ~ 3 ° ukubangela ukuvuza;
IiValves ezininzi zebhola ezinkulu ezinobungakanani ubukhulu becala zinezinto zokumisa. Ukuba zisetyenziswa ixesha elide, umhlwa, uthuli, ipeyinti kunye nezinye izinto ezingafunwayo ziya kuqokelelana phakathi kwesiqu nesinqandi sokumisa ngenxa yomhlwa nezinye izizathu. Ezi nkunkuma ziya kwenza ukusilela kwevalvevu kujikeleze endaweni kwaye kubangele ukuvuza-ukuba ivelufa ingcwatyiwe, ukwandisa isitshixo kuya kuvelisa kwaye kulahle ngakumbi umhlwa kunye nokungcola ukuthintela ibhola ukuba ijikeleze endaweni yayo, ibangele ukuba ivelufa ivuze;
Umqhubi jikelele ukwanqunyelwe. Ukuba ibangela umhlwa ixesha elide, ukuqina kwegrisi okanye ukukhulula iibholiti zomda, umda uya kuba ungachanekanga kwaye ubangele ukuvuza ngaphakathi;
Isikhundla sevalve ye-actuator yombane icwangciselwe phambili, kwaye ayivaliwe endaweni yokubangela ukuvuza ngaphakathi;
Ukungabikho kolondolozo lwamaxesha ngamaxesha kunye nokugcinwa, kubangela ukuba igrisi yokutywina yome kwaye iqine, kwaye igrisi yokutywina eyomileyo iqokeleleka emva kwesihlalo sevalvevu, ethintela isihlalo sevalve esihamba, esenza ukuba itywina lisilele.
