1. Khulisa ukuqina

Ngokushukuma nokudlidliza okuncane, ukuqina kungandiswa ukuze kususwe noma kubuthakathaka. Isibonelo, ukusebenzisa isipilingi esinokuqina okukhulu noma ukusebenzisa i-piston actuator kungenzeka.

2. Khulisa ukudambisa

Ukwandisa ukuminyana kusho ukwandisa ukungqubuzana ngokumelene nokudlidliza. Isibonelo, ipulaki yevalvu yevalvu yesikhafu ingavalwa ngendandatho ethi “O”, noma i-graphite filler enokungqubuzana okukhulu, okungadlala indima ethile ekuqedeni noma ekwenzeni buthaka ukudlidliza okuncane.

3. Khulisa usayizi womhlahlandlela bese unciphisa igebe lokulingana

Usayizi womhlahlandlela weamavalvu epulaki lomgodingokuvamile kuncane, kanti indawo ehambisanayo yawo wonke ama-valve ngokuvamile inkulu, kusukela ku-0.4 kuya ku-1 mm, okuwusizo ekudaleni ukudlidliza komshini. Ngakho-ke, lapho kwenzeka ukudlidliza okuncane komshini, ukudlidliza kungenziwa buthaka ngokwandisa usayizi womhlahlandlela nokunciphisa igebe lokufaka.

4. Shintsha ukuma kwe-throttle ukuze ususe i-resonance

Ngoba lokho okubizwa ngokuthi umthombo wokudlidliza weivalvu yokulawulakwenzeka echwebeni le-throttle lapho ukugeleza kwesivinini esikhulu kanye nokucindezela kushintsha ngokushesha, ukushintsha isimo selungu le-throttle kungashintsha imvamisa yomthombo wokudlidliza, okulula ukuyixazulula uma i-resonance ingekho ngamandla.

Indlela ethile iwukujika ubuso obugobile be-valve core ngo-0.5 ~ 1.0mm ngaphakathi kwebanga lokuvula lokudlidliza. Isibonelo,ivalvu yokulawula ingcindezi ezisebenzela yonaifakiwe eduze kwendawo yomndeni yefektri. Umsindo wokukhala kwekhwela obangelwa ukuzwakala kwekhwela uthinta abanye abasebenzi. Ngemva kokuba ubuso be-valve core bujikwe ngo-0.5mm, umsindo wokukhala kwekhwela kwekhwela uyanyamalala.

5. Buyisela ingxenye yokugoqa ukuze ususe ukugqama

Izindlela yilezi:

Shintsha izici zokugeleza, i-logarithmic ibe yi-linear, i-linear ibe yi-logarithmic;

Shintsha ifomu le-valve core. Isibonelo, shintsha uhlobo lwe-shaft plug lube yi-groove valve core efana no-“V”, bese ushintsha uhlobo lwe-shaft plug lwe-valve enezihlalo ezimbili lube uhlobo lwe-sleeve;

Shintsha umkhono wefasitela ube umkhono onezimbobo ezincane, njll.

Isibonelo, ivalvu enezihlalo ezimbili ye-DN25 esitshalweni sikamanyolo we-nitrogen yayivame ukudlidliza futhi iphule ukuxhumana phakathi kwesiqu sevalvu kanye nenhloko yevalvu. Ngemva kokuqinisekisa ukuthi kwakuyi-resonance, sashintsha inhloko yevalvu eqondile yaba yinhloko yevalvu ye-logarithmic, futhi inkinga yaxazululwa. Esinye isibonelo ivalvu yesikhafu se-DN200 esetshenziswa elabhorethri yekolishi lezindiza. Ipulaki yevalvu yajikeleza kakhulu futhi yayingenakusetshenziswa. Ngemva kokushintsha isikhafu ngefasitela ibe yingalo enembobo encane, ukujikeleza kwanyamalala ngokushesha.

6. Shintsha uhlobo lwevalvu elawulayo ukuze ususe ukugqama

Amaza emvelo ama-valve alawulayo anezinhlobo ezahlukene zesakhiwo ahlukile ngokwemvelo. Ukushintsha uhlobo lwe-valve elawulayo kuyindlela ephumelela kakhulu yokuqeda ukuzwakala komsindo ngokuyisisekelo.

Umsindo wevalvu unzima kakhulu ngesikhathi sokusetshenziswa - uyadlidliza kakhulu (ezimweni ezimbi kakhulu, ivalvu ingabhujiswa), ijikeleza ngamandla (ngisho nesiqu sevalvu siyadlidliza noma sisontekile), futhi sikhiqize umsindo onamandla (kufika kuma-decibel angaphezu kwe-100). Vele ufake ivalvu esikhundleni sayo ngevalvu enomehluko omkhulu wesakhiwo, futhi umphumela uzoba ngokushesha, futhi umsindo onamandla uzonyamalala ngokuyisimangaliso.

Isibonelo, ivalvu yesiketi se-DN200 ikhethiwe kuphrojekthi entsha yokwandisa yefektri ye-vinylon. Kukhona lezi zenzakalo ezintathu ezingenhla. Ipayipi le-DN300 liyagxuma, ipulaki yevalvu iyajikeleza, umsindo ungaphezu kwama-decibel ayi-100, kanti ukuvulwa kwe-resonance kungu-20 kuya ku-70%. Cabanga ngokuvulwa kwe-resonance. Izinga likhulu. Ngemva kokusebenzisa ivalvu enezihlalo ezimbili, i-resonance yanyamalala futhi ukusebenza kwaba okuvamile.

7. Indlela yokunciphisa ukudlidliza kwe-cavitation

Ngokudlidliza kwe-cavitation okubangelwa ukuwohloka kwamabhamuza e-cavitation, kungokwemvelo ukuthola izindlela zokunciphisa i-cavitation.

Amandla omthelela akhiqizwa ukuqhuma kwebhamuza awasebenzi endaweni eqinile, ikakhulukazi ingaphakathi le-valve, kodwa amuncwa uketshezi. Ama-valve e-sleeve analesi sici, ngakho-ke ingaphakathi le-valve yohlobo lwe-shaft plug lingashintshwa libe uhlobo lwe-sleeve.

Thatha zonke izinyathelo zokunciphisa ukugoba kwesisu, njengokwandisa ukumelana nokugoba, ukwandisa ingcindezi yokuncipha kwengcindezi, ukunciphisa ingcindezi okuhleliwe noma okuwuchungechunge, njll.

8. Gwema indlela yokuhlasela kwamagagasi omthombo wokudlidliza

Ukushaqeka kwamagagasi okuvela emithonjeni yokudlidliza yangaphandle kubangela ukudlidliza kwamavalvu, okuyinto okufanele igwenywe ngesikhathi sokusebenza okuvamile kwevalvu elawulayo. Uma kwenzeka ukudlidliza okunjalo, kufanele kuthathwe izinyathelo ezifanayo.
