Njengoba nje umsindo ungaba nomthelela ongemuhle emzimbeni womuntu, amafrikhwensi athile angadlala i-havoc emishini yezimboni lapho i-valve yokulawula ikhethiwe kahle, okuholela ekulimaleni okuphezulu, okuholela ekulimaleni okusheshayo kwamapayipi angaphakathi naphansi weisivalwana.

Ngaphezu kwalokho, amazinga omsindo aphezulu ngokuvamile enza ukudlidliza kungalimaza amapayipi, izinsimbi nezinye izintoIsivalwanaNgokuhamba kwesikhathi, ukuwohloka kwezakhi, i-valve cavitation ebangelwa uhlelo lwamapayipi ithambekele ekulimaleni okukhulu. Lo monakalo udalwa kakhulu ngamandla we-vibraineour Energy, inqubo esheshayo yokugqwala kanye ne-cavitation eboniswa yileveli ephezulu ye-amplity vibration ekhiqizwe yi-bubble ye-steam eduze nokwehla kwe-shrinkage.

Yize lokhu kuvame ukwenzeka ebholeniamavalvenama-rotary ama-rotary emzimbeni, empeleni kungenzeka ukuthi kutholakale okufushane, okuphezulu okufana nengxenye yomzimba we-v-ballisivalwana, ikakhulukaziama-butterfly valvesohlangothini oluphansi lwe-valve laphoisivalwanaIcindezelwa ngesikhundla esisodwa esithambekele ekuvuthweni kwe-canomenon, okuthambekele ekuvukeni kwamapayipi we-valve kanye nokulungiswa kwe-welding, i-valve ayilungele le ngxenye yomugqa.

Kungakhathalekile ukuthi ngabe i-cavitation yenzeka ngaphakathi kwe-valve noma phansi kwe-valve, imishini endaweni ye-cavitation izoba ngaphansi komonakalo omkhulu kumafilimu we-Ultra-mncane, iziphethu ze-amplity nezakhiwo ezincane zingadala ama-oscillations. Amaphoyinti wokuhluleka njalo atholakala kumathuluzi afana nengcindezi, ama-transmitters, ama-thermocouple imikhono, ama-flowmeters, ama-supling systems actUses aqukethe iziphethu azobhekana nokugqokwa okusheshayo, futhi ama-fasteners nezixhumi azokhulula futhi ahluleke ngenxa yokudlidliza.

Ukugqwala kokugqwala, okwenzeka phakathi kwezindawo ezigqokwa ezivezwa ukudlidliza, kuvamile eduze kwama-calvuta valves. Lokhu kukhiqiza ama-oxide anzima njengezifiso zokusheshisa ukugqoka phakathi kwezindawo ezigqokwa. Imishini ethintekile ifaka ukwehlukaniswa futhi ihlole ama-valves, ngaphezu kokulawula ama-valve, amaphampu, izikrini ezijikelezayo, ama-samplers kanye nanoma iyiphi enye indlela yokujikeleza noma yokushelela.

Izikhathi zokudlidliza okuphezulu zingena futhi ziqhekeze futhi zikhonkotha izingxenye zensimbi nezindonga zepayipi. Izinhlayiya zensimbi ezihlakazekile noma izinto zokulima amakhemikhali zingangcolisa abezindaba epayipini, ezingaba nomthelela omkhulu ekuhlanzeni kwe-hygienic valve piping kanye nemithombo yezindaba yokuhlanzeka okuphezulu. Lokhu futhi akuvunyelwe.

Ukubikezela ukwehluleka kwe-cavitation kwama-pug valves kuyinkimbinkimbi ngokwengeziwe futhi akubalwa nje ukwehla kwengcindezi. Umuzwa uphakamisa ukuthi kungenzeka ukuthi ingcindezi ekhefini eliyinhloko engcindezini ye-vapor ye-ketshezi ngaphambi komugqa wendawo kanye nokuwa kwe-bupble yendawo. Abanye abakhiqizi be-valve babikezela ukwehluleka kweChilo eChilo Indlela yomenzi we-valve yokuqalisa ngokubikezela ukukhiqizwa kwe-cavitation isuselwa eqinisweni lokuthi ama-bubblus asolayo awela, abangele ukuboshwa nomsindo. Kunqunywe ukuthi ukulimala okubalulekile kwe-cavitation kuzogwemeka uma izinga elibaliwe lomsindo lingaphansi kwemikhawulo ebhalwe ngezansi.

Usayizi we-valve ufinyelela kumasentimitha ama-3 - 80 db

Usayizi we-valve we-4-6 inches - 85 db

Usayizi we-Valve 8-14 Iches - 90 DB

Usayizi we-Valve wama-intshi ayi-16 nokukhudlwana - 95 dB

Izindlela zokuqeda umonakalo we-cavitation

I-Special Valve Design Ukuze uqede i-Cavitation esebenzisa ukugeleza okuhlukanisiwe kanye ne-grading cress trong:
"Ukuphambukiswa kwe-valve" ukwahlukanisa ukugeleza okukhulu kugeleza emincane emincane, futhi indlela yokugeleza ye-valve yakhelwe ukuze ukugeleza kugelezele ngokuvuleke okuncane okufanayo. Kusukela ingxenye yosayizi we-bubble ye-cavitation ibalwa ngokuvula lapho ukugeleza kudlula khona. Ukuvulwa okuncane kwenza ama-bubble amancane, okuholele emsindo omncane nomonakalo omncane uma kukhulunywa ngomonakalo.

"Ukwehla kwengcindezi yengcindezi" kusho ukuthi i-valve yakhelwe ukuba ibe namaphoyinti amabili noma ngaphezulu wokulungiswa kochungechunge, ngakho-ke esikhundleni sakho konke ukwehla kwengcindezi esinyathelweni esisodwa, kuthatha izinyathelo ezimbalwa ezincane. Ngaphansi kokudonswa kwengcindezi komuntu ngamunye kungavimba ingcindezi eShrinkage ekuweni kwengcindezi ye-vapor ye-FAPOR ye-ketshezi, ngaleyo ndlela iqede into ye-cavitation eValve.

Inhlanganisela yokuphambukisa nokucindezela kwehlisa isithunzi e-valve efanayo ivumela ukumelana kwe-cavitation okuthuthukisiwe. Ngesikhathi sokuguqulwa kwe-valve, ukubeka isikhundla se-valve yokulawula kanye nengcindezi yokungena kwe-valve kuphakeme (isib. Ngaphezulu ohlangothini olusezingeni eliphezulu, noma endaweni ephansi), kwesinye isikhathi okuqeda izinkinga ze-cavitation.

Ngaphezu kwalokho, ukubeka i-valve yokulawula endaweni yokushisa uketshezi, futhi ngenxa yalokho umfutho we-vapor ophansi (onjenge-extimen eshitsanger ephansi) ungasiza ukuqeda izinkinga ze-cavitation.

Isifinyezo sikhombisile ukuthi into ye-cavitation yama-valve ayigcini ngokusebenza kokuwohloka nomonakalo wama-valve. Amapayipi nemishini esekwe phansi futhi engcupheni. Ukubikezela i-cavitation nokuthatha izinyathelo zokuqeda yilapho kuphela indlela yokugwema inkinga yezindleko ezibizayo ze-valve ukusetshenziswa.
