Le khasiI-Valur Plate Plate Check ValveFuthi luhlobo lwe-valve ye-Checkve nge-activation ejikelezayo, kepha iyi-disc ephindwe kabili futhi ivalwe ngaphansi kwesenzo sentwasahlobo. I-disc icindezelwe ivulekile ngoketshezi olungezansi, i-valve inesakhiwo esilula, i-clamp ifakwe phakathi kwamafashi amabili, futhi usayizi omncane nesisindo esikhanyayo kuphansi.
Le khasiI-Valur Plate Plate Check ValveInama-disc amabili afakwe entwasahlobo afakwe emgodini onama-ribbed ngaphesheya kwe-valve. Lesi sakhiwo sinciphisa ibanga elithi isikhungo sokudonsela phansi kwe-disc sihamba. Lokwakhiwa futhi kunciphisa isisindo se-disc ngo-50% uma kuqhathaniswa ne-valve ye-swing-on eyodwa yosayizi ofanayo. Ngenxa yomthwalo wentwasahlobo, i-valve isabela ngokushesha ukubuyela emuva.
Ukwakhiwa okubili okubili okubhalwe phansi kwe-lobe
Isenzo sentwasahlobo esidala se-butterfly kabiliBheka i-valveIvumela i-disc ukuthi ivuleke futhi ivale ngaphandle kokuhlikihla isihlalo, futhi i-Spring isebenza ngokuzimela ukuvala i-disc (DN150 nangaphezulu).
Umkhono wokusekela owesilisa we-butterfly ephindwe kabiliBheka i-valveYehlisa ukungqubuzana futhi incishise isando samanzi lapho kukhishwe kukhishwe i-disc ehlukile (emnyama).
Qhathanisa nomhlanganoSwing hlola ama-valves,I-Valur Plate Plate Check ValveUkwakhiwa kuvame ukuqina, okulula, okuncane, okusebenzayo, futhi kubiza kakhulu. Leli valve lihlangabezana nezinga le-API 594, ngamamayela amaningi, usayizi wobuso bale valve kuphela i-valve evamile, kanti isisindo se-15% ~ 20% ye-valve evamile, ngakho-ke futhi kushibhile kune-valve yokuhlola evamile. Kulula futhi ukufaka phakathi kwama-gaskets ajwayelekile namaphaseli wepayipi. Ngoba kulula ukuphatha futhi idinga isethi eyodwa kuphela yama-Flange okuxhumeka ama-bolts, futhi asindise izingxenye ngesikhathi sokufakwa, ukonga izindleko zokufaka kanye nezindleko zansuku zonke zokulungiswa kwansuku zonke.
I-Valve ehlola i-Butterfly Butterfly i-Double futhi inezici ezikhethekile zokwakha ezenza le valve ibe yi-valve yokuhlola e-accerve ephezulu. Lezi zici azihlanganisi nokuvulwa okuhlanzekile, ukwakhiwa okuzimele kwentwasahlobo kwama-valves amaningi, kanye nezinhlelo ezizimele zokusekelwa kwe-Disc. Ezinye zalezi zici azitholakali ngama-valve ama-Check. I-valve ye-wafer e-pulwate eluhlaza okwesibili nayo ingahlelwa ngama-lugs, amavutha aphindwe kabili kanye nomzimba onwetshiwe.
Okokuqala, inqubo yokuvula nokuvala
Ukwakhiwa kwe-Double-Disc kubonisa ama-disc amabili alayishwe entwasahlobo (ama-semi-disc) amiswe kwiphini elinamakhanda eliqonde phezulu enkabeni. Lapho uketshezi luqala ukugeleza, i-disc ivula ngamandla (F) asebenza enkabeni yendawo yokubekwa uphawu. Amandla wokuxhaswa kwentwasahlobo okuphikisanayo (i-FS) asetshenziswa endaweni engaphandle enkabeni yobuso be-disc, abangele ukuthi impande ye-disc ivule kuqala. Lokhu kugwema ukungqubuzana ebusweni bokubekwa uphawu okwenzeka lapho i-disc ivulwa emathangeni amadala ajwayelekile, ukuqeda ukugqoka nokudabula izinyembezi.
Lapho isilinganiso sokugeleza sincipha, i-Torsion Spring iphendula ngokuzenzakalelayo, okwenza i-disc ivale futhi iqhubekele eduze kwesihlalo somzimba, yehlisa ibanga lokuhamba nesikhathi sokuvalwa nesikhathi sokuvalwa nesikhathi sokuvalwa nesikhathi sokuvalwa. Lapho uketshezi lugeleza emuva, kancane kancane i-disc isuka eduze kwesihlalo somzimba, futhi ukuphendula okunamandla kwe-valve kusheshiswa kakhulu, kunciphisa ukusebenza kwesando samanzi nokuthola ukusebenza kwamanzi.
Lapho kuvalwa, isenzo sendawo yesenzo samandla entwasahlobo sibangela phezulu kwe-disc ukuvala kuqala, ukuvimbela ukuluma nokuxabana empandeni ye-disc, ukuze i-valve ingalondoloze ubuqotho bophawu isikhathi eside.
2. Isakhiwo esizimele sentwasahlobo
Ukwakhiwa kwentwasahlobo (i-DN150 nangaphezulu) kuvumela i-torque enkulu ukuthi isetshenziswe ku-disc ngayinye kanye ne-disc ivala ngokuzimela njengokushintsha kwezimboni. Ukuhlolwa kukhombisile ukuthi lo mphumela uholele ekunyuseni ama-25% empilweni ye-valve kanye nokuncishiswa kwama-50% ngesando samanzi.
Ingxenye ngayinye ye-DOWS DIC ineziphethu zayo ezinikezela ngamandla azimele zokuvala futhi zitholwe ngaphansi kokukhishwa okuncane okungu-140 ° (Fig. 3) esikhundleni sentwasahlobo evamile enamabakaki amabili anamabakaki amabili.
3. Isakhiwo esizimele ukumiswa kwe-disc
Isakhiwo se-hinge esizimele sinciphisa ukungqubuzana ngo-66%, okuthuthukisa kakhulu ukusebenza kwe-valve. Umkhono wokusekelwa ufakwa kusuka ku-HInge engaphandle ukuze i-hinge ephezulu ingasekelwa ngokuzimela ngumkhono ophansi ngesikhathi sokusebenza kwe-valve. Lokhu kuvumela bobabili ama-disc ukuthi asabele ngokushesha futhi avale ngasikhathi sinye, ethola ukusebenza okuhle kakhulu okunamandla.
Okwesine, imodi yokuxhuma ngepayipi
I-Wafe Plate Plate Check valvesFuthi amapayipi angaxhunywa ngama-clamp, ama-lugs, amavutha, kanye nama-clamp.
