Kanye njengokuba isandi sinokuba nefuthe elibi emzimbeni womntu, ezinye iziphazamiso zinokudlala isiphoso kwizixhobo ezivela kwimizi-mveliso xa ivalve yokulawula ifanelekile, kukho umngcipheko omkhulu we-cavition, onokukhokelela kwi-chibid ephezulu kunye nemibhobho ye-onstream yeivalve.

Ukongeza, amanqanaba engxolo aphezulu anokubangela ukuntywila okunokuyonakalisa imibhobho, izixhobo kunye nezinye izixhoboIvalveNgokuhamba kwexesha, ukonakaliswa kwamacandelo, i-vavication ye-vavication ebangelwa yinkqubo ye-pipeline ethambekele kumonakalo onzulu. Lo monakalo ubangelwa kakhulu ngamandla engxolo yengxolo, inkqubo ekhawulezayo kunye ne-cavite ibonakaliswe linqanaba eliphezulu lengxolo lokutshintsha kwengqondo eveliswe yi-foam ye-lespment eveliswayo kwaye iwile i-steam ye-Steam ekufuphi.

Nangona oku kuhlala kwenzeka kwibholaivalikunye nee-valve ezijikelezayo emzimbeni, zinokuvela ngokufutshane, ukubuyela kwimeko yesiqhelo kuyafana ne-v-ibhola ye-V-ibholaivalve, ngakumbiI-Butterfly ValvesKwicala elisezantsi le-valve xaivalveIxinezelekile kwisikhundla esinye esixhonywe kwi-Cavitity phenomenon, ethambekele ekuphumeni kwi-piipung ye-valve kunye ne-welding, ivalve ilungele eli candelo lomgca.

Nokuba imeko ye-caviting yenzekile ngaphakathi kwe-valve okanye i-dowypream yevali, izixhobo kwindawo ye-caviting iya kuba phantsi kweefilimu ezinqabileyo, imithombo yecandelo elincinci le-ICREALDE). Amanqaku okusilela rhoqo afunyanwa kwizixhobo ezinje nge-gegues, ii-spermicleters, iinkqubo ze-uqhube, i-Speciators, i-Switch Ackeds, kunye nokunxibelelana kuya kukhululeka kwaye zisilele ngenxa yentshukumo.

I-frieting i-scoresion, eye yenzeka phakathi kwendawo enxibe i-vibration, ixhaphakile kufutshane neevalva zoboki. Oku kuvelisa i-oxides enzima njengoko i-aatresings yokukhawulezisa ukunxiba phakathi kwendawo enxibileyo. Isixhobo esichaphazelekayo siquka ukwahlula kunye nokujonga i-valves, ukongeza kwiivali zokulawula, iimpompo, izikrini ezijikelezayo, iisampulu kunye nayiphi na enye indlela yokujikeleza okanye yokutsala.

I-Ampling ePhezulu ye-Eughlist ikwanokuqhekeza kwaye ikhuphe iinxalenye ze-valve zensimbi kunye neendonga zombhobho. Amasuntswana athile asasazekileyo okanye izinto zokuthambisa iikhemikhali zinokungcolisa amajelo eendaba kumbhobho, onokuba nefuthe elibonakalayo kwi-voling valve ye-valve kunye nemithombo yeendaba. Oku akuvunyelwanga.

Ukuxelwa kwangaphambili kokusilela kwe-cavitication ngeephuli zeplagi kubaluleke kakhulu kwaye ayibalwa nje i-cercoves yexinzelelo. Amava acebisa ukuba kunokwenzeka ukuba uxinzelelo kumjelo ophambili lwehla kwi-vapor yolwelo lwe-vapor of lolwelo ngaphambi kokufumana i-vallsing yendawo kunye nokuwa kwetyhefu ye-steam. Abanye abavelisi bevalve baxela ukusilela kwangaphambili ukusilela ngokuchaza ukuhla koxinzelelo lokuqala. Indlela yeValve yomenzi yokuqalisa ngokubonisa ukonakaliswa kwe-cavitication isekwe kwinyaniso yokuba amatyhubhu e-steam ewa, ebangela i-cavitation kunye nengxolo. Kumiselwe ukuba umonakalo obalulekileyo womonakalo uya kuthintelwa ukuba inqanaba lengxolo eliliweyo lingaphantsi kwemida edweliswe ngezantsi.

Ubungakanani beValve ukuya kwi-3 intshi-80 dB

Ubungakanani beValve ye-4-6 i-intshi - 85 db

Ubungakanani beValve 8-14 i-intshi - 90 db

Ubungakanani be-velikhi bee-intshi ezili-16 kwaye bukhulu - 95 DB

Iindlela zokuphelisa ukonakala kwekhampasi

Uyilo olukhethekileyo lwe-valve ukuphelisa ukuqaphela usebenzisa ukuhamba kwe-phyff kunye ne-gract yoxinzelelo:
"I-vallion yokwahlula" kukwahlulahlula ukuhamba okuninzi kube kuhambo oluninzi oluncinci, kwaye indlela yokuhamba kweveve idalwe ukuze ukuhamba kwenani elincinci. Kuba isahlulo sobukhulu be-bubble ye-caviting ibalwa ngokuvula apho ukuhamba kwentshukumo. Ukuvulwa okuncinci kwenza ukuba iibhubhu ezincinci, zikhokelela kwingxolo engaphantsi kunye nomonakalo omncinci xa kufikwa kumonakalo.

"Ukucofa koxinzelelo komgangatho" kuthetha ukuba ivalve yenzelwe ukuba ibe namanqaku amabini okanye ngaphezulu kohlengahlengiso lohlengahlengiso, ke endaweni yoxinzelelo olupheleleyo kwinyathelo elinye, kuthatha amanyathelo amaninzi. Ngaphantsi koxinzelelo lwengcinezelo lomntu onokuthintela uxinzelelo kwi-shrinkage ukusuka kwi-speinkige kwi-vapor yoxinzelelo lwe-vapor yolwelo, ngaloo ndlela iphelise imeko yobuqhetseba kwivalve.

Ukudityaniswa kokuphambukisa kunye noxinzelelo lwehla kwindawo enye kwi-velip enye ivumela ukuphuculwa kokuphuculwa kokuphuculwa kwe-cavitication. Ngexesha lokulungiswa kwe-valve, ukubeka ivalve yokulawula kunye nengcinezelo yevalve iphezulu (umz. Ukuphakama kwe-pirstream ephezulu, ngamanye amaxesha kuphelisa iingxaki zobukhulu.

Ukongeza, ukubeka i-valve yokulawula kwindawo yeqondo lobushushu lolwelo, kwaye ke i-vaporar ye-vapor ephantsi (njengamaqondo obushushu asezantsi asezantsi anokunceda ukuphelisa iingxaki.

Isishwankathelo sibonisile ukuba i-cavication ye-valves ayikho kuphela malunga nokusebenza kwetyala kunye nomonakalo weevila. Imibhobho ye-Dowredam kunye nezixhobo zisengozini. Ukuxela kwangaphambili ukuthatha amanyathelo kwaye uthathe amanyathelo okuphelisa kuphela kwendlela yokuphepha ingxaki yeendleko zokusebenzisa i-valve ezibizayo.
