Zithini izinto ezingalunganga ze-valves ye-wafer?

II-Wial Steend Plateal ValveIkwanohlobo lwevalve yokujonga enoluvo olujikelezayo, kodwa yi-disc ephindwe kabini kwaye ivale phantsi kwesenzo sentwasahlobo. I-disc ityhalwe ivuliwe ngamanzi aphantsi-up, ivalve inesakhiwo esilula, i-clamp ifakwe phakathi kweeflethi ezimbini, kwaye ubungakanani obuncinci kunye nobunzima bokukhanya buphantsi.

II-Wial Steend Plateal ValveIne-discs ezimbini zentwasahlobo ezinomthwalo obekwe kwi-shaft ye-ribbed kwivalve ivele. Eli sakhiwo linciphisa umgama ukuba iziko lokuhluma kwe-disc liyahamba. Olu lwakhiwo luphelisa ubunzima bediski nge-50% xa kuthelekiswa ne-disc-kwi-swing ye-Swing-kwi-valve ye-swing yesayizi. Ngenxa yomthwalo wentwasahlobo, ivalve iqala ngokukhawuleza kakhulu ukuya kubude.

　　Iplastikhi yesibini ye-vante valve-lobe i-vanve-lobe i-bane ne-lobe iqhuba itywina kunye nokusebenza ngokufanelekileyo.

　　Intshukumo yentwasanqa elideJonga i-valveivumela i-disc ukuba ivule kwaye ivale ngaphandle kokuhlikihla isitulo, kwaye izenzo zentwasahlobo ngokuzimela ngokuzimeleyo ukuvala i-disc (DN150 nangaphezulu).

　　Inkxaso yenkxaso ye-Hinged ye-Butter-Flapply ByterflyJonga i-valveinciphisa ukuxabana kwaye inciphise isando samanzi xa ikhutshiwe kwi-disc ye-disc (enkulu).

Xa kuthelekiswa neqhelekileyoI-swing jonga i-valves,I-Wial Steend Plateal ValveUlwakhiwo luqhelekile, lukhanyise, luncinci, lusebenza ngakumbi, kwaye lungabizi kakhulu. Le valve idibana nenqanaba le-API 594, uninzi lweedayamitha, ubukhulu becala ebusweni yi-1/4 ye-valve yesiqhelo, kwaye ubunzima be-vaing valve, ngoko ke kuyabiza ivalve ye-swing. Kulula ukufaka phakathi kwe-galls esemgangathweni kunye neeflethi zombhobho. Kuba kulula ukuphatha kwaye kufuna iseti enye kuphela yee-bolts zoqhagamshelo lweflethi, ikwagcina izinto ngexesha lokufakwa, ukugcina iindleko zokugcina kunye neendleko zokulungisa zemihla ngemihla.

Ivalve ephindwe kabini-bhabha yebhabhathane ineempawu ezizodwa zokwakha ezenza ukuba le valve ibe yi-valve entsebenzo ephezulu yempembelelo yempembelelo. Ezi mpawu zibandakanya ukuvulwa okucocekileyo, kulwakhiwo oluzimeleyo lwentwasahlobo kwiiValves ezininzi, kunye neenkqubo ezizimeleyo ze-disc. Ezinye zezi zinto azifumaneki ngeevavu zetshekhi. I-vanthey ye-wapt yeplate ye-wapt ingenziwa yi-lugs, iflethi ezimbini kunye nomzimba owandisiweyo.

Okokuqala, inkqubo yokuvula kunye nokuvala

Ukwakhiwa kwe-disc-mbini kubonakalisa iidiski ezimbini zentwasahlobo (i-semi-discs) inqunyanyisiwe kwi-pinged pinged ethe nkqo kwiziko. Xa ulwelo luqala ukuhamba, i-disc ivula kunye namandla emibi (f) isebenza embindini womphezulu wokutywina. Inkxaso yenkxaso yentwasahlobo yentwasahlobo (i-FS) isetyenziswa kwisikhundla esingaphandle embindini wediski, ebangela ingcambu yokuvula ukuze ivulwe kuqala. Oku kuyakuphephe ukungqubana kumgangatho wokutywina okwenzeka xa i-disc ivulwa kwiivali eziqhelekileyo eziqhelekileyo, zisusa impahla kunye nokukrazula kwamacandelo.

Xa inqanaba lokuhamba lihla, i-torsation i-torsation iqala ngokuzenzekelayo, ibangela ukuba idiski ivale kwaye isondele kwisitulo somzimba, sinciphisa umgama wokuhamba kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala kunye nexesha lokuvala. Xa ulwelo luhamba umva, ngokuthe ngcembe i-discly ihamba kufutshane nesitulo somzimba, kwaye impendulo eguqukayo yevali ikhawuleziswa kakhulu, ukunciphisa ifuthe lokusebenza kwamanzi kunye nokufezekisa intsebenzo yasimahla.

Xa kuvalwa, isenzo senqaku lesenzo sokunyanzeliswa kwentwasahlobo ibangela ukuba i-disc ivale kuqala, ukuthintela ukuluma kunye nokugqobhoza kwingcambu yetyhefu ixesha elide.

2. Ulwakhiwo lweentwasahlobo

Ulwakhiwo lwentwasahlobo (DN150 nangaphezulu) ivumela i-torque enkulu ukuba isetyenziswe kwi-disc nganye kunye ne-disc ivale ngokuzimeleyo njengoko utshintsho olwenziwe kwimizi mveliso. Iimvavanyo zibonakalisile ukuba le mpembelelo ibangele ukunyuka kwe-25% kubomi be-veli kunye nokuncitshiswa kwe-50% kwi-hammer yamanzi.

Icandelo ngalinye le-disc eliphindwe kabini linemigaqo yayo ebonelela ngamandla okuvala okuzimeleyo kwaye iphantsi kwe-Angcular encinci ye-140 ° (Fig.

I-3. Ukuzimela okuthile kwi-disc

Isakhiwo esizimeleyo se-hinge sinciphisa ukungqubana ngama-66%, nto leyo ephucula kakhulu i-vallves. I-hingeve yenkxaso ifakwe ngaphandle kwe-hinge ngaphandle kokuba i-hinge ephezulu ixhaswe ngokuzimeleyo ngumkhono ophantsi ngexesha lokusebenza kwe-valve ngexesha lokusebenza kwe-valve. Oku kuvumela zombini iidiski zokusabela ngokukhawuleza kwaye zivale ngaxeshanye, iphumelele ukusebenza okugqibeleleyo.

Isine, indlela yoqhagamshelo kunye nombhobho

I-valt ye-wanKwaye imibhobho inokuqhagamshelwa kunye neekhonkwane, ii-lugs, flames, kunye ne-clamps.
