Iingcebiso kunye neengongoma eziphambili zokukhetha iivalve zokukhupha ezingaphezulu kunye nezisezantsi ngokweemfuno zenkqubo

1, Intshayelelo

Kwiinkqubo ezahlukeneyo zemveliso yemizi-mveliso, i-valve yokukhupha i-up and down, njengesixhobo sokulawula ulwelo oluqhelekileyo, zisetyenziswa ngokubanzi kwiinkqubo zokuhambisa, ukudibanisa, kunye nobungakanani bokutya komgubo, i-granular, kunye ne-fibrous materials. Ukhetho oluchanekileyo lokunyuka kunye nokuhla kwee-valve zokukhupha i-valve kunokuqinisekisa iinkqubo zokuvelisa ezigudileyo, ukuphucula ukusebenza kakuhle kwemveliso, kunye nokunciphisa iindleko zokusebenza. Eli nqaku liza kubonelela ngentshayelelo eneenkcukacha malunga nendlela yokukhetha iivalvu zokukhupha ezingaphezulu nezisezantsi ngokweemfuno zenkqubo, ukunceda abafundi ukuba basebenzise ubuchule obuphambili kunye namanqaku aphambili.

2, Imigaqo yokukhetha

1. Iimpawu zezinto eziphathekayo

Xa ukhetha i-valve yokukhupha i-up and down, into yokuqala ekufuneka uyiqwalasele yimpawu eziphathekayo, kubandakanywa ukufuma, ubungakanani besuntswana, ubuninzi, ukuchasana nokunxiba, njl. Ngokomzekelo, kwizinto eziphathekayo ezinokumelana nokuqina okunamandla, iivalve zokukhupha izinto eziphathekayo kufuneka zikhethwe.

2. Iimfuno zenkqubo

Ngokweemfuno zenkqubo yokuvelisa, izinga lokuhamba, uxinzelelo, ubushushu kunye nezinye iiparitha ekufuneka i-valve yokukhupha kufuneka ihlangabezane nazo zizinto eziphambili zokukhethwa. Ngokomzekelo, kwiindawo eziphakamileyo zokushisa kunye noxinzelelo oluphezulu, i-valve yokukhupha i-valve kufuneka ikhethwe.

3. Imathiriyeli yezixhobo

Izinto eziphathekayo zevalve yokukhupha kufuneka zikhethwe ngokusekelwe kwi-corrosiveness of the material. Kwizinto eziphathekayo ezinobuqhophololo obuqinileyo, izinto ezichasene ne-corrosion ezifana nensimbi engenasici, i-titanium alloy, njl. Kufuneka zikhethwe kwiivalve zokukhupha.

4. Indlela yokufakela

Khetha indlela efanelekileyo yokufakela ngokusekelwe kubukhulu bendawo yezixhobo kunye neemeko zendawo, ezifana nokufakwa kwecala, ukufakwa okuphezulu, njl.

5. Ulawulo olukrelekrele

Ngokusekwe kwinqanaba lokwenziwa kwe-automation yemveliso, khetha ukuba ufuna i-valve yokukhupha kunye nemisebenzi yokulawula ehlakaniphile, njengolawulo lwe-PLC, ukusebenza kwesikrini sokuchukumisa, njl.

3, Amanyathelo okukhetha

1. Qinisekisa uhlobo lwevalve yokukhupha

Ngokusekelwe kwiimpawu zemathiriyeli kunye neemfuno zenkqubo, misela iindidi ze-valve zokukhupha ezinyukayo kunye nezisezantsi, ezifana ne-flap, i-butterfly, i-spiral, njl.

2. Khetha imilinganiselo efanelekileyo yevalve yokukhupha

Khetha imilinganiselo yevalvu yokukhupha efanelekileyo ngokusekwe kwisantya sokuqukuqela kwenkqubo, idiameter yombhobho, kunye nezinye iiparamitha.

3. Qinisekisa izinto eziphathekayo zevalve yokukhupha

Khetha izinto ezifanelekileyo zevalve yokukhupha ngokusekelwe kwi-corrosiveness kunye nokuguga kwezinto.

4. Cinga indlela yokuqhuba ivalve yokukhupha

Ngokweemfuno zenkqubo, khetha i-pneumatic, umbane, i-manual kunye nezinye iindlela zokuqhuba.

5. Khetha iimpawu ezongezelelweyo

Ngokweemfuno zemveliso, khetha ukuba ngaba imisebenzi eyongezelelweyo iyafuneka, njengeqondo lokushisa kunye noxinzelelo, i-pneumatic, iinkqubo zokulawula umbane, njl.

6. Qinisekisa indlela yokufakela i-valve yokukhupha

Misela indlela yokufakela i-valve yokukhupha ngokusekelwe kubukhulu bendawo yesixhobo kunye neemeko zesayithi.

4. Isiphelo

Ukukhethwa okuchanekileyo kwee-valve zokukhupha ezingaphezulu kunye nezisezantsi kuyisitshixo sokuqinisekisa iinkqubo zokuvelisa ezigudileyo, ukuphucula ukusebenza kakuhle kwemveliso, kunye nokunciphisa iindleko zokusebenza. Ndiyathemba ukuba eli nqaku linokubonelela ngeereferensi eziluncedo kunye nesikhokelo kubafundi kumsebenzi osebenzayo. Kwinkqubo yokhetho, kuyimfuneko kwakhona ukwenza uhlalutyo olucacileyo olusekwe kwimeko ethile yokuvelisa ukuqinisekisa ukukhethwa kwee-valve zokukhupha ezifanelekileyo kunye nezithembekileyo eziphezulu kunye nezantsi.
