Namuhla, umhleli uzokwethula ukuthi ungabhekana kanjani namaphutha avamile ama-valve okulawula. Ake sibheke!

Yiziphi izingxenye okufanele zihlolwe lapho kwenzeka iphutha?

1. Udonga lwangaphakathi lomzimba we-valve

Udonga lwangaphakathi lomzimba we-valve luvame ukuba nomthelela futhi ludliwe yi-medium lapho ama-valve alawulayo esetshenziswa kuzilungiselelo zemidiya ezihlukile zokucindezela okuphezulu kanye nokugqwala, ngakho-ke kubalulekile ukunaka ekuhloleni ukugqwala nokumelana nokucindezela.

2. Isihlalo se-valve

Ingxenye engaphakathi yentambo evikela isihlalo sevalvu igqwala ngokushesha lapho i-valve elawulayo isebenza, okuholela ekutheni isihlalo sevalvu sixege. Lokhu kungenxa yokungena kwesikhulumi. Lapho uhlola, gcina lokhu engqondweni. Indawo yokuvala isihlalo se-valve idinga ukuhlolwa ukuze iwonakele ngenkathi i-valve isebenza ngaphansi kokwehluka okukhulu kwengcindezi.

3. Spool

I-valve yokulawulaingxenye enyakazayo uma isebenza ibizwa ngokuthi ii-valve core. Yilona abezindaba abalilimaze futhi baligugulela kakhulu. Yonke ingxenye ye-valve core idinga ukuthi ukuguga nokugqwala kwayo kuhlolwe kahle ngesikhathi sokulungiswa. Kumele kuqashelwe ukuthi ukugqoka kwe-valve core (i-cavitation) kunzima kakhulu uma ukuhlukana kwengcindezi kukhulu. Kuyadingeka ukulungisa i-valve core uma yonakaliswe kakhulu. Ngaphezu kwalokho, kufanele ukhumbule noma yiziphi izenzakalo ezifanayo esiqwini se-valve kanye nanoma yikuphi ukuxhumana okuxekethile nomongo we-valve.

4. "O" izindandatho namanye ama-gaskets

Noma ngabe iyaguga noma iyaqhekeka.

5. PTFE ukupakisha, uphawu amafutha

Kungakhathaliseki ukuthi iyaguga nokuthi indawo yokukhwelana ilimele, kufanele ishintshwe uma kunesidingo.

I-valve elawulayo yenza umsindo, yini okufanele ngiyenze?

1. Qeda umsindo ozwakalayo

Amandla ngeke ambozwe kuze kube yilapho ivalvu elawulayo izwakala, idala umsindo omkhulu ongaphezu kuka-100 dB. Ezinye zinomsindo ophansi kodwa ukudlidliza okunamandla, ezinye zinomsindo omkhulu kodwa ukudlidliza okubuthakathaka, kuyilapho ezinye zinomsindo nokudlidliza okukhulu.

Imisindo yethoni eyodwa, ngokuvamile kumafrikhwensi aphakathi kuka-3000 no-7000 Hz, ikhiqizwa yilo msindo. Yebo, umsindo uzozihambela wona uma i-resonance isusiwe.

2. Susa umsindo we-cavitation

Isizathu esiyinhloko somsindo we-hydrodynamic yi-cavitation. Isiphithiphithi esinamandla sendawo nomsindo we-cavitation kukhiqizwa umthelela wesivinini esikhulu okwenzeka lapho amabhamuza ewa ngesikhathi se-cavitation.

Lo msindo unobubanzi obubanzi befrikhwensi nomsindo okhencezayo okhumbuza uketshezi oluqukethe amatshe nesihlabathi. Enye indlela ephumelelayo yokususa nokunciphisa umsindo ukunciphisa nokunciphisa i-cavitation.

3. Sebenzisa amapayipi anezindonga eziwugqinsi

Enye inketho yokubhekana nomzila womsindo ukusebenzisa amapayipi anezindonga eziqinile. Ukusetshenziswa kwamapayipi anezindonga eziwugqinsi kunganciphisa umsindo ngama-decibel angu-0 kuye kwangama-20, kuyilapho amapayipi anezindonga ezincane engandisa umsindo ngama-decibel amahlanu. Ukuqina komphumela wokunciphisa umsindo, udonga lwamapayipi olunobubanzi obufanayo lwepayipi luba lukhudlwana futhi ubukhulu bepayipi lobukhulu obufanayo buba bukhulu.

Isibonelo, inani lokunciphisa umsindo lingaba -3.5, -2 (okungukuthi, liphakanyisiwe), 0, 3, no-6 lapho ukushuba kodonga lwepayipi le-DN200 kungu-6.25, 6.75, 8, 10, 12.5, 15, 18, 20 , kanye no-21.5mm, ngokulandelana. 12, 13, 14, kanye no-14.5 dB. Ngokwemvelo, izindleko zikhuphuka ngokuqina kodonga.

4. Sebenzisa izinto ezimunca umsindo

Lena futhi indlela ethandwa kakhulu futhi ephumelelayo yokucubungula izindlela zomsindo. Amapayipi angasongwa ngezinto ezimunca umsindo ngemuva kwamavalvu nemithombo yomsindo.

Kubalulekile ukukhumbula ukuthi umsindo uhamba amabanga amade ngokugeleza koketshezi, ngaleyo ndlela ukusebenzisa amapayipi anezindonga eziwugqinsi noma ukugoqa izinto ezimunca umsindo ngeke kuwuqede ngokuphelele umsindo.

Ngenxa yezindleko zayo eziphakeme, le ndlela ifaneleka kangcono ezimweni lapho amazinga omsindo ephansi nobude bamapayipi bufushane.

5.Series muffler

Umsindo we-Aerodynamic ungaqedwa ngokusebenzisa le nqubo. Inamandla okwehlisa ngempumelelo izinga lomsindo oxhunywe kusendlalelo esiqinile sokuvimbela nokuqeda umsindo ngaphakathi koketshezi. Ukugeleza kwesisindo esikhulu noma izindawo zesilinganiso sokwehla komfutho ophezulu ngaphambi nokulandela i-valve zifaneleka kakhulu umnotho nokusebenza kwale ndlela.

Izithulisi ezisemgqeni ezimuncwayo ziyindlela esebenzayo yokunqamula umsindo. Noma kunjalo, ukuncipha ngokuvamile kukhawulelwe ku-25 dB ngenxa yezinto zezindleko.

6. Ibhokisi elingenamsindo

Sebenzisa amabhokisi angazwakali, izindlu nezakhiwo ukuze uhlukanise imithombo yomsindo yangaphakathi futhi unciphise umsindo wemvelo wangaphandle ube ibanga elamukelekayo.

7. Uchungechunge lwe-throttling

Indlela ye-throttling yochungechunge isetshenziswa lapho ukucindezela kwevalvu elawulayo kuphakeme ngokuqhathaniswa (△P/P1≥0.8). Lokhu kusho ukuthi konke ukwehla kwengcindezi kusatshalaliswa phakathi kwe-valve elawulayo kanye nesici esigxilile se-throttling ngemuva kwe-valve. Izindlela ezingcono kakhulu zokunciphisa umsindo ngamapuleti okunciphisa ukugeleza kwe-porous, ama-diffuser, njll.

I-diffuser kumele yakhelwe ngokuhambisana nomklamo (isimo somzimba, usayizi) ukuze uthole ukusebenza kahle kwe-diffuser.
