Amathiphu namaphuzu abalulekile okukhetha ama-valve okukhipha ukwanda okuphezulu nangaphansi ngokuya ngezidingo zenqubo

1. Isandulela

Ezinqubweni ezihlukahlukene zokukhiqiza ezimbonini, ama-valve akhipha ukunwetshwa akhuphuka naphansi, njengethuluzi elivamile lokulawula uketshezi, asetshenziswa kakhulu ezinhlelweni zokudlulisa, zokuhlanganisa, kanye nenani lokuphakela lempushana, imbudumbudu, kanye ne-fibrous. Ukukhethwa okulungile kwama-valve okukhipha ukwanda okunwetshiwe kungaqinisekisa izinqubo zokukhiqiza ezibushelelezi, kuthuthukise ukusebenza kahle kokukhiqiza, nokunciphisa izindleko zokusebenza. Lesi sihloko sizohlinzeka ngesethulo esiningiliziwe sendlela yokukhetha ama-valve okukhipha ukwanda okuphezulu nangaphansi ngokuya ngezidingo zenqubo, ukusiza abafundi baqonde amasu abalulekile namaphuzu abalulekile.

2, Izimiso zokukhetha

1. Izici zezinto ezibonakalayo

Uma ukhetha ama-valve okukhipha ukunwetshwa akhuphukayo naphansi, into yokuqala okufanele icatshangelwe yizici zezinto ezibonakalayo, okuhlanganisa umswakama, usayizi wezinhlayiyana, ukuminyana, ukumelana nokugqokwa, njll. Izidingo zokukhetha zama-valve akhiphayo anezici ezihlukile zezinto ziyahlukahluka. Isibonelo, ezintweni ezinokumelana nokugqoka okuqinile, ama-valve okukhipha impahla angagqoke kufanele akhethwe.

2. Izidingo zenqubo

Ngokwezidingo zenqubo yokukhiqiza, izinga lokugeleza, ingcindezi, izinga lokushisa kanye neminye imingcele i-valve yokukhipha okudingeka ihlangabezane nayo nazo ziyizici ezibalulekile zokukhethwa. Isibonelo, endaweni yokushisa ephezulu kanye nenqubo yokucindezela okuphezulu, i-valve yokukhishwa kwe-high-temperature kanye nokucindezela okuphezulu kufanele kukhethwe.

3. Impahla yesisetshenziswa

Impahla ye-valve yokukhipha kufanele ikhethwe ngokusekelwe ekubaleni kwezinto. Okwezinto zokwakha ezinokugqwala okuqinile, izinto ezimelana nokugqwala njengensimbi engagqwali, ingxubevange ye-titanium, njll. kufanele kukhethwe ama-valve akhiphayo.

4. Indlela yokufaka

Khetha indlela yokufaka efanele ngokusekelwe kusayizi wesikhala sezinto zokusebenza nezimo zesayithi, njengokufakwa kwezinhlangothi, ukufakwa okuphezulu, njll.

5. Ukulawula okuhlakaniphile

Ngokusekelwe ezingeni lokukhiqiza okuzenzakalelayo, khetha ukuthi udinga yini i-valve yokukhipha enezici zokulawula ezihlakaniphile, njengokulawula kwe-PLC, ukusebenza kwesikrini esithintwayo, njll.

3, Izinyathelo zokukhetha

1. Nquma uhlobo lwe-valve yokukhipha

Ngokusekelwe ezicini zezinto zokwakha nezidingo zenqubo, nquma izinhlobo zamavalvu okukhipha anwebekayo akhuphukayo naphansi, njenge-flap, uvemvane, i-spiral, njll.

2. Khetha imininingwane efanelekile ye-valve yokukhipha

Khetha ukucaciswa kwevalvu yokukhipha efanele okusekelwe kuzinga lokugeleza kwenqubo, ububanzi bepayipi, neminye imingcele.

3. Nquma impahla ye-valve yokukhipha

Khetha impahla efanele ye-valve yokukhipha ngokusekelwe ekonakaleni nasekugugeni kwempahla.

4. Cabanga ngemodi yokushayela ye-valve yokukhipha

Ngokwezidingo zenqubo, khetha izindlela zokushayela zomoya, zikagesi, zemanuwali nezinye.

5. Khetha izici ezengeziwe

Ngokwezidingo zokukhiqiza, khetha ukuthi ingabe imisebenzi eyengeziwe iyadingeka, njengezinzwa zokushisa nokucindezela, i-pneumatic, izinhlelo zokulawula ugesi, njll.

6. Qinisekisa indlela yokufaka i-valve yokukhipha

Nquma indlela yokufaka i-valve yokukhipha ngokusekelwe kusayizi wesikhala semishini kanye nezimo zesayithi.

4. Isiphetho

Ukukhethwa okulungile kwama-valve okukhipha ukwanda okungaphezulu naphansi kuyisihluthulelo sokuqinisekisa izinqubo zokukhiqiza ezibushelelezi, ukuthuthukisa ukusebenza kahle kokukhiqiza, nokunciphisa izindleko zokusebenza. Ngethemba ukuthi lesi sihloko singanikeza izinkomba eziwusizo nesiqondiso kubafundi emsebenzini osebenzayo. Enqubweni yokukhetha, kuyadingeka futhi ukwenza ukuhlaziya okuningiliziwe okusekelwe esimweni esithile sokukhiqiza ukuze kuqinisekiswe ukukhethwa kwama-valve okukhishwa okunwebekayo aphezulu naphansi afanelekile futhi anokwethenjelwa.
