Njengoba nje umsindo ungaba nomthelela omubi emzimbeni womuntu, amaza athile angalimaza imishini yezimboni uma i-valve yokulawula ikhethwe kahle, kunengozi eyengeziwe yokucasuka, okuzoholela emazingeni aphezulu omsindo kanye nokudlidliza, okuholela ekulimaleni okusheshayo kakhulu kumapayipi angaphakathi nawaphansi omfula.ivalvu.

Ngaphezu kwalokho, amazinga aphezulu omsindo avame ukubangela ukudlidliza okungalimaza amapayipi, izinsimbi kanye neminye imishiniIvalvungokuhamba kwesikhathi, ukuwohloka kwezingxenye, ukuvalwa kwe-valve okubangelwa uhlelo lwamapayipi oluthambekele ekulimaleni okukhulu. Lo monakalo ubangelwa kakhulu amandla omsindo wokudlidliza, inqubo yokugqwala esheshisiwe kanye nokuvalwa kwe-cavitation okubonakaliswa yizinga eliphezulu lomsindo wokudlidliza okukhulu okubangelwa ukwakheka nokuwa kwamabhamuza omusi eduze nangaphansi komfudlana wokuncipha..

Nakuba lokhu kuvame ukwenzeka ebholeniamavalvukanye nama-valve ajikelezayo emzimbeni, kungenzeka ngempela ekupholeni okufushane, okuphezulu okufana nengxenye yomzimba we-wafer yebhola le-Vivalvu, ikakhulukaziamavalvu ebhabhathaneohlangothini olungezansi lwevalvu laphoivalvuuma icindezelekile endaweni eyodwa ithambekele ekubeni ne-cavitation, okuyinto ethambekele ekuvuzeni amapayipi e-valve kanye nokulungiswa kokushisela, i-valve ayifanele lesi sigaba somugqa.

Kungakhathaliseki ukuthi i-cavitation iyenzeka ngaphakathi kwe-valve noma phansi kwe-valve, imishini endaweni ye-cavitation izolimala kakhulu kumafilimu amancane kakhulu, iziphethu kanye nezakhiwo ezincane ze-cantilever, ukudlidliza okukhulu kwe-amplitude kungabangela ukunyakaza. Amaphuzu okwehluleka okuvamile atholakala kumathuluzi afana nama-pressure gauge, ama-transmitter, imikhono ye-thermocouple, ama-flowmeter, izinhlelo zokuthatha amasampula Ama-Actuators, ama-positioner kanye nama-limit switch aqukethe iziphethu azoguga ngokushesha, futhi ama-bracket okufaka, ama-fasteners kanye nama-connectors azokhululeka futhi ahluleke ngenxa yokudlidliza.

Ukugqwala okungapheli, okwenzeka phakathi kwezindawo ezigugile ezivezwe ekudlidlizeni, kuvamile eduze kwama-valve e-cavitation. Lokhu kukhiqiza ama-oxide aqinile njengezinto ezisusa ukuguguleka ukuze kusheshiswe ukuguguleka phakathi kwezindawo ezigugile. Imishini ethintekile ifaka phakathi ama-valve okuhlukaniswa nokuhlola, ngaphezu kwama-valve okulawula, amaphampu, izikrini ezijikelezayo, amasampula kanye nanoma iyiphi enye indlela ejikelezayo noma eshelelayo.

Ukudlidliza okuphezulu kungaqhekeka futhi kugqwale izingxenye zamavalvu ensimbi kanye nezindonga zamapayipi. Izinhlayiya zensimbi ezihlakazekile noma izinto zamakhemikhali ezigqwalisayo zingangcolisa imidiya ephayiphini, okungaba nomthelela omkhulu kumapayipi e-valve ahlanzekile kanye nemidiya yamapayipi ahlanzekile kakhulu. Lokhu futhi akuvunyelwe.

Ukubikezela ukwehluleka kwe-cavitation kwama-plug valve kuyinkimbinkimbi kakhulu futhi akugcini ngokubalwa nje ukwehla kwengcindezi yokugoba. Okuhlangenwe nakho kusikisela ukuthi kungenzeka ukuthi ingcindezi emfudlaneni oyinhloko yehle iye ekucindezelweni komphunga woketshezi ngaphambi kokuhwamuka kwendawo kanye nokuwa kwebhamuza lomusi. Abanye abakhiqizi bama-valve babikezela ukwehluleka kwe-eclipse ngaphambi kwesikhathi ngokuchaza ukwehla kwengcindezi yomonakalo wokuqala. Indlela yomenzi wama-valve yokuqala ngokubikezela umonakalo we-cavitation isekelwe eqinisweni lokuthi amabhamuza omusi ayawa, okubangela i-cavitation nomsindo. Kutholakale ukuthi umonakalo omkhulu we-cavitation uzogwenywa uma izinga lomsindo elibalwe lingaphansi kwemingcele ebhalwe ngezansi.

Usayizi wevalvu ufika kumasentimitha angu-3 - 80 dB

Usayizi wevalvu ongamasentimitha angu-4-6 - 85 dB

Usayizi wevalvu 8-14 amasentimitha - 90 dB

Usayizi wamavalvu angamasentimitha angu-16 nangaphezulu – 95 dB

Izindlela zokuqeda umonakalo we-cavitation

Umklamo we-valve okhethekile wokuqeda i-cavitation usebenzisa ukugeleza okuhlukanisiwe kanye nokwehla kwengcindezi okulinganiselwe:
“Ukuphambuka kwevalvu” ukuhlukanisa ukugeleza okukhulu kube ukugeleza okuncane okuningana, futhi indlela yokugeleza kwevalvu yakhelwe ngendlela yokuthi ukugeleza kugeleze ezimbotsheni ezincane eziningana ezifanayo. Njengoba ingxenye yobukhulu bebhamuza le-cavitation ibalwa ngembobo lapho ukugeleza kudlula khona. Imbobo encane ivumela amabhamuza amancane, okuholela emsindweni omncane kanye nomonakalo omncane uma kukhulunywa ngomonakalo.

“Ukwehla kwengcindezi okunezinga” kusho ukuthi ivalvu yakhelwe ukuba namaphuzu okulungisa amabili noma ngaphezulu ngokulandelana, ngakho esikhundleni sokwehla kwengcindezi yonke ngesinyathelo esisodwa, kuthatha izinyathelo ezimbalwa ezincane. Ukwehla kwengcindezi okungaphansi koyedwa kungavimbela ingcindezi ekuncipheni ekucindezelweni komphunga woketshezi, ngaleyo ndlela kuqedwe isimo se-cavitation kuvalvu.

Inhlanganisela yokushintshashintsha kanye nokwehla kwengcindezi ku-valve efanayo ivumela ukumelana kwe-cavitation okuthuthukisiwe. Ngesikhathi sokuguqulwa kwe-valve, ukubeka i-valve yokulawula kanye nengcindezi ekungeneni kwe-valve kuphakeme (isb. ohlangothini olungaphezulu komfula, noma ekuphakameni okuphansi), ngezinye izikhathi kususa izinkinga ze-cavitation.

Ngaphezu kwalokho, ukubeka i-valve yokulawula endaweni yokushisa koketshezi, ngakho-ke umfutho ophansi womusi (njenge-heat exchanger eseceleni yokushisa ephansi) kungasiza ekuqedeni izinkinga ze-cavitation.

Isifinyezo sibonise ukuthi isenzakalo sokucavita kwama-valve empeleni asikona nje kuphela ukusebenza kokuwohloka kanye nomonakalo wama-valve. Amapayipi nemishini engezansi nawo asengozini. Ukubikezela ukucavita nokuthatha izinyathelo zokukuqeda kuyindlela kuphela yokugwema inkinga yezindleko ezibizayo zokusetshenziswa kwama-valve.
