Yikuphi ukonakala kwamavalvu okuhlola ama-wafer?

Ii-valve yokuhlola ipuleti elicwecwe kabilifuthi iwuhlobo lwe-valve yokuhlola ene-rotary actuation, kodwa i-double disc futhi ivala ngaphansi kwesenzo se-spring. I-disc iphushwa ivuleke uketshezi olusuka phansi luye phezulu, i-valve inesakhiwo esilula, i-clamp ifakwe phakathi kwama-flange amabili, futhi usayizi omncane nesisindo esilula siphansi.

Ii-valve yokuhlola ipuleti elicwecwe kabiliinamadiski amabili alayishwe entwasahlobo amise okwe-D abekwe kushafti elinezimbambo ngaphesheya kwesibhobo sevalvu. Lesi sakhiwo sifinyeza ibanga lapho isikhungo samandla adonsela phansi esihamba ngaso. Lokhu kwakhiwa futhi kunciphisa isisindo se-disc ngo-50% uma kuqhathaniswa ne-valve yokuhlola i-disc-swing-on yesayizi efanayo. Ngenxa yomthwalo wentwasahlobo, i-valve isabela ngokushesha kakhulu ekugelezeni emuva.

  Ukwakhiwa kwe-wafer dual plate check valve ye-double-lobe lightweight kwenza ukuvala isihlalo nokusebenza kusebenze kahle.

  Isenzo sentwasahlobo sengalo ende yovemvane oluphindwe kabilihlola i-valveivumela i-disc ukuthi ivuleke futhi ivale ngaphandle kokuhlikihla isihlalo, futhi isiphethu sisebenza ngokuzimela ukuvala i-disc (DN150 nangaphezulu).

  Umkhono wokusekela onehingi wovemvane oluphepha kabilihlola i-valveinciphisa ukungqubuzana futhi inciphise isando samanzi lapho ikhishwa ngediski ehlukile (ibhore elikhulu).

Uma kuqhathaniswa nezivamileama-valve wokuhlola jika,i-valve yokuhlola ipuleti elicwecwe kabiliukwakha ngokuvamile kunamandla, kulula, kuncane, kusebenza kahle kakhulu, futhi kungabizi kakhulu. Le valve ihlangabezana nezinga le-API 594, kumadiamitha amaningi, ubukhulu bobuso nobuso bale valve buyi-1/4 kuphela ye-valve evamile, futhi isisindo singu-15% ~ 20% we-valve evamile, ngakho-ke futhi ishibhile kune-valve yokuhlola i-swing. Kulula futhi ukufaka phakathi kwama-gaskets ajwayelekile nama-pipe flanges. Ngenxa yokuthi kulula ukuyiphatha futhi idinga isethi eyodwa kuphela ye-flange yokuxhuma amabhawudi, iphinde igcine izingxenye ngesikhathi sokufakwa, ukonga izindleko zokufaka kanye nezindleko zokulungisa nsuku zonke.

I-valve yokuhlola i-butterfly ephindwe kabili inezici ezikhethekile zokwakha ezenza le valve ibe i-valve yokuhlola engasebenzi kahle. Lezi zici zifaka ukuvulwa okungahlanzekile, ukwakhiwa kwentwasahlobo okuzimele kwamavalvu amaningi abhorekile, nezinhlelo ezizimele zokusekela idiski. Ezinye zalezi zici azitholakali kuma-valve okuhlola. Ivalve yokuhlola ipuleti eyisicwecwana ingabuye iklanywe ngama-lugs, ama-flange aphindwe kabili nomzimba owandisiwe.

Okokuqala, inqubo yokuvula nokuvala

Ukwakhiwa kwama-double-disc kunama-disc amabili alayishwe entwasahlobo (ama-semi-disc) amiswe kuphinikhodi enamahinge eqondile phakathi nendawo. Lapho uketshezi luqala ukugeleza, i-disc ivula ngamandla angumphumela (F) osebenza phakathi nendawo yokuvala uphawu. I-counteractive spring support force (FS) isetshenziswa endaweni engaphandle kwesikhungo sobuso bediski, okwenza impande yediski ivuleke kuqala. Lokhu kugwema ukungqubuzana endaweni yokuvala okwenzeka lapho i-disc ivulwa kuma-valve avamile amadala, eqeda ukuguga nokudabuka ezingxenyeni.

 

Lapho izinga lokugeleza linciphisa, isiphethu se-torsion sisabela ngokuzenzakalelayo, okwenza i-disc ivale futhi isondele eduze kwesihlalo somzimba, kunciphisa ibanga lokuhamba kanye nesikhathi sokuvala. Lapho uketshezi lugeleza emuva, i-disc kancane kancane isondela eduze kwesihlalo somzimba, futhi impendulo eguquguqukayo ye-valve ishesha kakhulu, inciphisa umphumela wesando samanzi nokufeza ukusebenza okungenamthelela.

 

Lapho uvala, isenzo sephuzu lesenzo se-spring force senza ukuba phezulu kwediski kuvalwe kuqala, kuvimbele ukuluma nokungqubuzana empandeni yediski, ukuze i-valve ikwazi ukugcina ubuqotho bophawu isikhathi eside.

 

2. Isakhiwo sentwasahlobo esizimele

 

Ukwakhiwa kwentwasahlobo (i-DN150 nangaphezulu) kuvumela ukuthi kusetshenziswe i-torque enkulu kudiski ngayinye futhi i-disc ivala ngokuzimela njengoba ukugeleza kwezimboni kushintsha. Ukuhlola kubonise ukuthi lo mphumela ubangele ukwanda kwama-valve ngama-25% kanye nokuncipha kwesando samanzi ngamaphesenti angama-50.

 

Ingxenye ngayinye ye-double disc ineziphethu zayo ezihlinzeka ngamandla okuvala okuzimele futhi ingaphansi kwe-offset encane ye-angular ye-140 ° (umdwebo 3) esikhundleni se-350 ° yesiphethu esivamile esinamabakaki amabili.

3. Isakhiwo esizimele sokumiswa kwediski

 

Isakhiwo esizimele sehinge kunciphisa ukungqubuzana ngo-66%, okuthuthukisa kakhulu ukusebenza kabusha kwe-valve. Umkhono wokusekela ufakwa kusukela kuhinge yangaphandle ukuze ihinge engaphezulu ikwazi ukusekelwa ngokuzimela ngomkhono ongezansi ngesikhathi sokusebenza kwevalvu. Lokhu kuvumela womabili amadiski ukuthi asabele ngokushesha futhi avale ngesikhathi esisodwa, azuze ukusebenza okuhle kakhulu okushukumisayo.

 

Okwesine, imodi yokuxhuma ngepayipi

 

Ama-valve okuhlola amapuleti ama-wafer amabilifuthi amapayipi angaxhunywa ngama-clamp, ama-lugs, ama-flange, nama-clamp.
