Kanye njengokuba isandi sinokuba nefuthe elibi emzimbeni womntu, amaza athile anokudlala indima embi kwizixhobo zoshishino xa ivalvu yokulawula ikhethwe ngokufanelekileyo, kukho umngcipheko okhulayo wokucaphuka kwemithambo yegazi, nto leyo eya kukhokelela kwingxolo ephezulu kunye namanqanaba okungcangcazela, nto leyo ekhokelela kumonakalo okhawulezileyo kwimibhobho yangaphakathi neyasezantsi yomlambo.ivalvu.

Ukongeza, amanqanaba aphezulu engxolo adla ngokubangela ukungcangcazela okunokonakalisa imibhobho, izixhobo kunye nezinye izixhoboIvalvungokuhamba kwexesha, ukonakala kwezinto, ukuxinana kwevalvu okubangelwa yinkqubo yemibhobho esengozini yokonakala okukhulu. Lo monakalo ubangelwa kakhulu ngamandla engxolo yokungcangcazela, inkqubo yokugqwala ekhawulezileyo kunye nokuxinana kwecavitation okubonakaliswa yingxolo ephezulu yokungcangcazela okukhulu okubangelwa kukwakheka nokuwa kwamaqamza omphunga kufutshane nasezantsi kokuncipha..

Nangona oku kudla ngokukwenzeka ebholeniiivalvukunye neevalvu ezijikelezayo emzimbeni, zinokwenzeka ngokwenene ekubuyiseleni okufutshane, okuphezulu okufana nenxalenye yomzimba we-wafer yebhola ye-V.ivalvu, ngakumbiiivalvu zebhabhathanekwicala elisezantsi levalvu xaivalvuixinezelekile kwindawo enye enokubangelwa yimeko yokuxinana kwemithambo yegazi, enokuvuza kwimibhobho yevalvu kunye nokulungiswa kwewelding, ivalvu ayifanelekanga kweli candelo lomgca.

Nokuba i-cavitation iyenzeka ngaphakathi kwevalvu okanye ngezantsi kwevalvu, izixhobo ezikwindawo ye-cavitation ziya konakaliswa kakhulu ziifilimu ezincinci kakhulu, izipringi kunye nezakhiwo ezincinci ze-cantilever, ukungcangcazela okukhulu kwe-amplitude kunokubangela ukushukuma. Iindawo zokusilela rhoqo zifumaneka kwizixhobo ezifana nee-pressure gauges, ii-transmitters, ii-thermocouple sleeves, ii-flowmeters, iinkqubo zesampulu Ii-Actuators, ii-positioners kunye nee-limit switches ezinezipringi ziya konakaliswa ngokukhawuleza, kwaye ii-brackets zokufaka, ii-fasteners kunye nee-connectors ziya kukhululeka kwaye zingasebenzi ngenxa yokungcangcazela.

Ukubola okubangelwa kukungcangcazela, okwenzeka phakathi kweendawo ezigugileyo ezivezwe kukungcangcazela, kuqhelekile kufutshane neevalvu ze-cavitation. Oku kuvelisa ii-oxides eziqinileyo njengezinto ezirhabaxa ukuze kukhawuleziswe ukuguguleka phakathi kweendawo ezigugileyo. Izixhobo ezichaphazelekileyo ziquka ukuhlukaniswa kunye neevalvu zokujonga, ukongeza kwiivalvu zokulawula, iipompo, izikrini ezijikelezayo, iisampuli kunye nayo nayiphi na enye indlela ejikelezayo okanye etyibilikayo.

Ukungcangcazela okuphezulu kunokwaphuka nokugqwala iindawo zevalvu zesinyithi kunye neendonga zepayipi. Amasuntswana esinyithi aqhekeziweyo okanye izinto zeekhemikhali ezirhabaxa zinokungcolisa imidiya ekwipayipi, nto leyo enokuba nefuthe elikhulu kwipayipi yevalvu ecocekileyo kunye nemidiya yepayipi ecocekileyo kakhulu. Oku akuvumelekanga.

Ukuqikelela ukungaphumeleli kwe-cavitation kwiivalvu zeplagi kuyinkimbinkimbi ngakumbi kwaye akubalwa nje ukuhla koxinzelelo lwe-choke. Amava abonisa ukuba kunokwenzeka ukuba uxinzelelo olukumjelo ophambili luyehla luye kuxinzelelo lomphunga wolwelo ngaphambi kokuba indawo iphume umphunga kwaye idilike kwibhamuza yomphunga. Abanye abavelisi beevalvu baqikelela ukungaphumeleli kwe-eclipse ngaphambi kwexesha ngokuchaza ukuhla koxinzelelo lomonakalo wokuqala. Indlela yomenzi weevalvu yokuqala ngokuqikelela umonakalo we-cavitation isekelwe kwinto yokuba amaqamza omphunga ayawa, okubangela i-cavitation kunye nengxolo. Kuye kwafunyaniswa ukuba umonakalo omkhulu we-cavitation uya kuthintelwa ukuba inqanaba lengxolo elibaliweyo lingaphantsi kwemida edweliswe ngezantsi.

Ubungakanani bevalvu ukuya kuthi ga kwi-intshi ezi-3 - 80 dB

Ubungakanani bevalvu obuyi-4-6 intshi – 85 dB

Ubungakanani bevalvu 8-14 intshi – 90 dB

Ubungakanani beevalvu eziyi-16 intshi nangaphezulu – 95 dB

Iindlela zokususa umonakalo we-cavitation

Uyilo olukhethekileyo lwevalvu lokususa i-cavitation lusebenzisa ukuhamba okuqhekekileyo kunye nokwehla koxinzelelo olulinganisiweyo:
"Ukuphambuka kwevalvu" kukwahlula umjelo omkhulu ube yimijelo emincinci emininzi, kwaye indlela yomjelo wevalvu yenzelwe ukuba umjelo udlule kwiindawo ezininzi ezincinci ezihambelanayo. Ekubeni inxalenye yobukhulu beqamza le-cavitation ibalwa ngomjelo odlula kuwo umjelo. Umjelo omncinci uvumela amaqamza amancinci, nto leyo ebangela ingxolo encinci kunye nomonakalo omncinci xa kuziwa kumonakalo.

“Ukuhla koxinzelelo olunemigangatho” kuthetha ukuba ivalvu yenzelwe ukuba ibe neendawo ezimbini okanye ngaphezulu zokulungisa ngokulandelelana, ngoko ke endaweni yokuhla koxinzelelo lonke kwinqanaba elinye, kuthatha amanyathelo amancinci ambalwa. Ukuhla koxinzelelo olungaphantsi kunokuthintela uxinzelelo olukwincindi ekuweni koxinzelelo lomphunga wolwelo, ngaloo ndlela kupheliswe imeko ye-cavitation kwivalvu.

Ukudibanisa ukujika kunye nokunciphisa uxinzelelo kwivalvu enye kuvumela ukuxhathisa okuphuculweyo kwe-cavitation. Ngexesha lokuguqulwa kwevalvu, ukubeka ivalvu yokulawula kunye noxinzelelo kwindawo yokungena yevalvu kuphezulu (umz. kwicala elingaphezulu komsinga, okanye kubude obuphantsi), ngamanye amaxesha kususa iingxaki ze-cavitation.

Ukongeza, ukubeka ivalvu yokulawula kwindawo yobushushu bolwelo, kwaye ngenxa yoko uxinzelelo oluphantsi lomphunga (njengomatshini wokutshintsha ubushushu obuphantsi) kunokunceda ukuphelisa iingxaki ze-cavitation.

Isishwankathelo sibonise ukuba i-cavitation ye-valve ayipheleli nje ekuwohlokeni kokusebenza kunye nomonakalo we-valve. Iipayipi kunye nezixhobo ezisezantsi nazo zisemngciphekweni. Ukuqikelela i-cavitation kunye nokuthatha amanyathelo okuyisusa yindlela ekuphela kwayo yokuphepha ingxaki yeendleko ezibizayo zokusetyenziswa kwe-valve.
