Indima ye-valves yezokuphepha kanye nokukhethwa kwazi!

Okokuqala, yini i-valve yokuphepha

I-HIRFRERT SALTREMENTVE Valve uhlobo lwe-valve olusetshenziselwa ukuvikela imishini yokuqapha kanye nokuphepha kohlelo, kungokwe-othomathikhi yokusiza izimpumpuna. I-valve yokuphepha ivame ukwakhiwa komzimba we-valve, ikhava ye-valve, intwasahlobo, i-spool kanye nemihlahlandlela. Izingxenye zalo zokuvula nokuvala endaweni evalekile elivalekile, lapho ingcindezi ye-mad ephakathi kohlelo lokuqapha idlula inani lokuphepha lizovulwa ngokuzenzakalela, ngokuvimbela ipayipi elithile ngaphandle kwesistimu, ukuze ivikele ipayipi noma imingcwabo ye-maild ephakathi. I-valve yezokuphepha ohlelweni lweqandisini ukuze idlale indima yokuvikela ukuphepha.

Okwesibili, kungani ufake ama-valves okuphepha

Ama-valves okuphepha asetshenziselwa ikakhulukazi ukuvikela imishini yokuqapha kanye nemikhumbi yengcindezi (njengamathangi okugcina aketshezi, ama-condensers), njll. Kumonakalo odalwe ngokucindezela ngokweqile. Lokhu okulandelayo kunezizathu eziningana zokuthi kungani ama-valves ezokuphepha adinga ukufakwa:

1. Ukuvimbela ukuqhuma kwemishini: Lapho ingcindezi ngaphakathi kwemishini yefriji noma umthambo wengcindezi idlula inani lokucindezela elibekwe yi-valve yezokuphepha, i-valve yezokuphepha izovulekela ngokuzenzakalelayo ukukhipha amanzi noma i-vessel.

2. Ukuvikela ukuphepha kwabasebenzi: Ingcindezi eyeqile ingahle iholele ekuqhumeni kwemishini noma ukuvuza, okwenza ukulimala ku-opharetha. Ukufakwa kwama-valves okuphepha kunganciphisa ingcindezi ngesikhathi ukuvikela ukuphepha kwabasebenzi.

3. Ukugwema ukwehluleka kohlelo: Ukucindezela ngokweqile kungadala ukulimala kohlelo lwefindisi, njengokuqhuma kwamapayipi, ukulimala kwemishini, njll. Ukufakwa kwama-valves okuphepha kungagwema lokhu kwehluleka. Ukufakwa kwe-valve yephepha lokuphepha kungagwema lokhu kwehluleka futhi kunwebe impilo yenkonzo yohlelo.

4. Hlangana nezidingo zokulawula: Ngokusho kwemithetho kanye namazinga afanele, eminye imishini yefriji nemithambo yengcindezi kufanele ifakwe ngama-valves okuphepha ukuze kuqinisekiswe ukuhambisana nezidingo zokuphepha.

Okwesithathu, izici zokuphepha ze-Valve Valve okufanele zicatshangelwe

Ekukhetheni ama-valves okuphepha, lezi zinto ezilandelayo zidinga ukubhekwa:

1 Isibonelo, imithombo yezemithombo ehlukene yefriji, izidingo zokushisa zokushisa nezidingo zokucindezela zizothinta ukukhethwa kwama-valve ezokuphepha.

2. Izidingo zokugeleza: Ngokwezidingo zokugeleza kohlelo, khetha i-valve efanelekile yokuphepha. Izinga eliphezulu lokugeleza kanye nezinga elincane lokugeleza kohlelo kudingeka kubhekwe ukuze kuqinisekiswe ukuthi i-valve yezokuphepha ingahlangabezana nezidingo zohlelo.

3. Uhla lwengcindezi ye-valve yezokuphepha: Ngokusho kobubanzi bokusebenza kwengcindezi yohlelo, khetha i-valve efanelekile yokuphepha. Ingcindezi esethiwe ye-valve yezokuphepha kufanele ibe ngaphezulu kakhulu kunengcindezi yokusebenza ephezulu yohlelo ukuze uqinisekise ukuthi ingavulwa ngesikhathi lapho uhlelo lufika ekucindezelweni okukhulu.

I-4 Imidiya ehlukene ingahle ibe nomthelela owonakalisayo kwi-valve yezokuphepha, ngakho-ke udinga ukukhetha izinto ezingavikeleki ukonakala.

I-5. Isitifiketi se-Valve Certification kanye nezindinganiso zokuhambisana

I-6. Ukucatshangelwa kwezinye izinto: ngokuya ngezidingo ezithile, cabanga ngokulungiswa kwe-valve yezokuphepha, izindlela zokufaka, izidingo zokulungisa kanye nokulungisa.
