Iivalvu zokukhangela ziyafumaneka kwiintlobo ngeentlobo kunye neenkcukacha ngokwezinto ezifana nesakhiwo, izinto ezisetyenzisiweyo kunye nokusetyenziswa kwazo. Oku kulandelayo sisishwankathelo esineenkcukacha zeentlobo kunye neenkcukacha zeevalvu zokukhangela:
Okokuqala, uhlobo
1. Uhlulo ngokwesakhiwo
Ivalvu yokujonga ilifti: Ivalvu yokujonga enediski etyibilikayo ecaleni komgca osembindini womzimba. Le valve inokufakelwa kuphela kumbhobho othe tye, i-coefficient yokumelana nolwelo inkulu. Xa i-medium ikwindlela yokuhamba, idiski yevalvu ivulwa ngokutyhalwa yi-medium. Xa i-medium iyeka ukuhamba, idiski yevalvu iwela esihlalweni ngobunzima bayo ukuthintela i-medium ukuba ingangeni kwi-countercurrent. Ivalvu yokujonga ilifti ineentlobo ezimbini ze-straight through kunye ne-vertical, ivalvu yokujonga ilifti ethe tye, i-medium inlet kunye ne-outlet channel direction kunye ne-seat channel direction perpendicular, kunye ne-vertical lift check check valve medium inlet kunye ne-outlet channel direction kunye ne-seat channel direction ziyafana, ukumelana kwayo nokuhamba kuncinci kunohlobo oluthe tye.
Ivalvu yokujonga iswingi: Ivalvu yokujonga enediski efana nediski kunye nentshukumo ejikelezayo ejikeleze umngxuma ojikelezayo wetshaneli yesihlalo. Ukumelana kwayo ngokubanzi kungaphantsi kunevalvu yokujonga yokuphakamisa, efanelekileyo kwiimeko ezinkulu ze-caliber. Iivalvu zokujonga iswingi zinokwahlulwa zibe yivalvu enye, ivalvu ephindwe kabini kunye neevalvu ezininzi ngokwenani leevalvu, injongo ephambili kukuthintela i-medium ekumiseni ukuhamba okanye ukuhamba okungasemva, okwenza kube buthathaka impembelelo ye-hydraulic.
Ivalvu yokujonga ibhabhathane: Ivalvu yokujonga enediski ejikeleza iphini esitulweni. Ivalvu yokujonga idiski ilula ngokwesakhiwo, inokufakelwa kuphela kumbhobho othe tye, kwaye ayinayo itywino ilungileyo.
Ivalvu yokujonga umbhobho: Ivalvu yokujonga enediski etyibilikayo kumgca osembindini womzimba. Yivalvu entsha evele, inobukhulu obuncinci, inobunzima obuphantsi, iteknoloji yokucubungula elungileyo, yenye yeendlela zophuhliso lweevalvu zokujonga.
Ivalvu yokujonga uxinzelelo: Le valve inomsebenzi odibeneyo wevalvu yokujonga ukuphakama kunye nevalvu yeglobe okanye ivalvu ye-Angle, kwaye idla ngokusetyenziswa njengevalvu yokusika amanzi kunye nomphunga kwibhoyila.
Ezinye iintlobo: Zikwabandakanya ivalvu yokujonga uhlobo lobunzima, ivalvu yokujonga uhlobo lwesitya, ivalvu yokujonga idiski yebrake, ivalvu yokujonga uhlobo lwebhola, ivalvu yokujonga uhlobo lwediaphragm.
2. Hlela ngokwezinto eziphathekayo
Ivalvu yokujonga isinyithi: efana nevalvu yokujonga isinyithi esityhidiweyo, ivalvu yokujonga ubhedu, ivalvu yokujonga isinyithi esingenasici, ivalvu yokujonga isinyithi esikhabhoni, ivalvu yokujonga isinyithi esenziwe ngomgunyathi, njl.
Ivalvu yokujonga engeyoyesinyithi: efana nevalvu yokujonga yeplastiki, ivalvu yokujonga ye-FRP, njl.
3. Hlela ngokwemisebenzi
Ivalvu yokujonga ethuleyo: efana nevalvu yokujonga ethuleyo ye-DRVZ, ivalvu yokujonga ethuleyo ye-DRVG, ivalvu yokujonga ethuleyo ye-NRVR, njl.
Ivalvu yokujonga eyenzelwe injongo ekhethekileyo: njengevalvu yokujonga iflaphu yerabha yeSFCV, ivalvu yokujonga iflaphu ephindwe kabini yeDDCV, njl.
Okwesibini, iinkcukacha
Iinkcukacha zevalvu yokujonga zihlala zibonakaliswa yi-nominal diameter (DN), kwaye iinkcukacha eziqhelekileyo ziyi-DN15, DN25, DN50, DN80, DN100, DN150, njl. Ukongeza, kukho iinkcukacha ezifana namanqanaba oxinzelelo, iintlobo zoqhagamshelo (ezifana noqhagamshelo olunemisonto, olujijekileyo, oluweldiweyo kunye nolunamathelisi).
Umzekelo, iinkcukacha zevalvu yokujonga intwasahlobo yentambo yangaphakathi ye-H12W yi-DN15-100mm, kwaye udidi loxinzelelo yi-1.6-32MPa; Iinkcukacha zevalvu zokujonga ibhabhathane ze-H76H kunye ne-H76W ezinediski ezimbini yi-DN50-1200mm, kwaye udidi loxinzelelo yi-1.6-10MPa.
Okwesithathu, khetha iingcebiso
Xa ukhetha ivalvu yokujonga, kuyimfuneko ukuqwalasela izinto ezifana nenkqubo ethile yemibhobho, iimpawu eziphakathi, uxinzelelo lokusebenza kunye nobushushu. Nazi ezinye iindlela:
Khetha uhlobo lwevalvu yokujonga efanelekileyo kunye neenkcukacha ngokwendlela yokuhamba kwayo kunye nobungakanani bokuhamba kwayo.
Cinga ngokugqwala komgangatho ophakathi, uburhabaxa kunye nobushushu kunye nezinye izinto, khetha izinto ezifanelekileyo.
Khetha imo yoqhagamshelo efanelekileyo ngokusekelwe kwindawo yokufakela kunye neemfuno zokugcinwa kwenkqubo yepayipi.
Nxibelelana nekhathalogu yemveliso yomenzi kunye nephepha leenkcukacha zobugcisa ukuqinisekisa ukuba ivalvu yokujonga ekhethiweyo iyahlangabezana neemfuno zenkqubo.
Ngamafutshane, kukho iintlobo ngeentlobo kunye neenkcukacha zeevalvu zokujonga, kwaye ukhetho kufuneka luqwalaselwe ngokupheleleyo ngokweemfuno zokwenyani.
