Ivalve yeDiphragm

Ivalve ye-diaphragmsisivalo esivalayo esisebenzisa idiaphragm njengenxalenye yokuvula neyokuvala ukuvala umjelo wokuhamba, ukusika ulwelo, nokwahlula umngxuma ongaphakathi womzimba wevalvu kumngxuma ongaphakathi wesivalo.I-diaphragm ihlala yenziwe ngerabha, iplastiki kunye nezinye i-elastiki, i-corrosion-resistant, kunye nezixhobo ezingenakungena.Umzimba wevalvu ubukhulu becala wenziwe ngeplastiki, ifayibha yeglasi yeplastiki eyomeleziweyo, i-ceramic okanye imathiriyeli enerabha yentsimbi.Ulwakhiwo olulula, ukutywinwa okulungileyo kunye nokusebenza okuchasene nokubola, kunye nokumelana nolwelo oluphantsi.Isetyenziselwa imidiya kunye noxinzelelo oluphantsi, ubushushu obuphantsi, ukubola okunamandla kunye nomcimbi omisiweyo.Ngokutsho kwesakhiwo, kukho uhlobo lwephahla, uhlobo lwe-cut-off, uhlobo lwesango kunye nokunye.Ngokwendlela yokuqhuba, ihlukaniswe yaba yi-manual, i-pneumatic kunye nombane.
 
Ubume bevalve ye-diaphragm yahluke kakhulu kwivalve jikelele.Luhlobo olutsha lwevalve kunye nefom ekhethekileyo yevalve yokusika.Inxalenye yayo yokuvula kunye nokuvala yi-diaphragm eyenziwe ngezinto ezithambileyo.Umgodi wangaphakathi wekhava kunye nenxalenye yokuqhuba iyahlukana kwaye ngoku isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Izivalo zediaphragm ezisetyenziswa ngokuqhelekileyo ziquka iivalvu zediaphragm ezinerabha, ivalve ene-fluorine-lined diaphragm, iivalvu zediaphragm ezingafakwanga mgca, kunye neplastiki ye-diaphragm valves.
Ivalve ye-diaphragm ixhotyiswe nge-diaphragm eguquguqukayo okanye i-diaphragm edibeneyo kumzimba wevalve kunye nesivalo sevalvu, kwaye indawo yayo yokuvala sisixhobo sokucinezela esidityaniswe ne-diaphragm.Isihlalo sevalve sinokubunjwa nge-weir, okanye inokuba ludonga lombhobho odlula kumjelo wokuhamba.Inzuzo ye-valve ye-diaphragm kukuba indlela yokusebenza kwayo ihlukaniswe kwi-paseji ephakathi, engaqinisekisi nje ukucoceka kwendawo yokusebenza, kodwa iphinde ithintele ukuba kungenzeka ukuba i-medium kwipayipi ithintele iindawo zokusebenza zendlela yokusebenza.Ukongezelela, akukho mfuneko yokusebenzisa naluphi na uhlobo lwesitywina esahlukileyo kwi-valve stem, ngaphandle kokuba isetyenziswe njengendawo yokukhusela ekulawuleni imidiya eyingozi.Kwivalve ye-diaphragm, kuba indawo esebenzayo inxibelelana kuphela ne-diaphragm kunye nomzimba wevalvu, zombini ezinokusebenzisa izinto ezahlukeneyo ezahlukeneyo, ivalve inokulawula ngokufanelekileyo iintlobo ngeentlobo zemithombo yeendaba esebenzayo, ngakumbi ilungele ukugqwala kweekhemikhali okanye ukunqunyanyiswa. amasuntswana aphakathi.Iqondo lokushisa elisebenzayo levalve ye-diaphragm lihlala lilinganiselwe ngezinto ezisetyenziswa kwi-diaphragm kunye ne-valve yomzimba we-valve, kunye nomgangatho wokushisa osebenzayo malunga -50～175℃.Ivalve ye-diaphragm inesakhiwo esilula, esinamalungu amathathu kuphela: i-valve body, i-diaphragm kunye nendibano yentloko yevalve.I-valve ilula ukuchithwa ngokukhawuleza kunye nokulungiswa, kwaye ukutshintshwa kwe-diaphragm kunokugqitywa kwisayithi kunye nexesha elifutshane.
 
Umgaqo wokusebenza kunye nokwakhiwa:
Ivalve ye-diaphragm isebenzisa umzimba we-lining-resistant-resistant and corrosion-resistant diaphragm endaweni ye-valve core assembly, kunye nokuhamba kwe-diaphragm kusetyenziselwa ukulungiswa.Umzimba wevalve yevalve ye-diaphragm yenziwe ngentsimbi etyhidiweyo, intsimbi etyhidiweyo, okanye intsimbi engatyiwayo, kwaye ifakwe kwizinto ezahlukeneyo ezinganyangekiyo okanye zinxibe, irabha ye-diaphragm kunye ne-polytetrafluoroethylene.I-diaphragm ye-lining inokumelana ne-corrosion eyomeleleyo kwaye ilungele ukulungiswa kwemithombo yeendaba ezomeleleyo ezifana ne-asidi eyomeleleyo kunye ne-alkali eyomeleleyo.
Ivalve ye-diaphragm inesakhiwo esilula, ukuxhathisa ulwelo oluphantsi, kunye nomthamo omkhulu wokuhamba kunezinye iintlobo zeevalvu zenkcazo efanayo;ayinakuvuza kwaye ingasetyenziselwa ukulungiswa kwe-viscosity ephezulu kunye nemidiya ye-particulate emisiwe.I-diaphragm ihlukanisa i-medium ukusuka kumngxuma ophezulu we-valve stem, ngoko akukho ndlela yokupakisha kwaye akukho kuvuza.Nangona kunjalo, ngenxa yokunciphisa i-diaphragm kunye nezixhobo ze-lining, ukumelana noxinzelelo kunye nokumelana nobushushu akubi, kwaye ngokuqhelekileyo kufanelekile kuphela kuxinzelelo oluqhelekileyo lwe-1.6MPa nangaphantsi kwe-150 ° C.
Uphawu lokuhamba kwevalve ye-diaphragm isondele kwimpawu yokuvula ngokukhawuleza, ephantse ibe ngumgca phambi kwe-60% ye-stroke, kwaye izinga lokuhamba emva kwe-60% alitshintshi kakhulu.Iivalve ze-diaphragm ze-pneumatic nazo ziyakwazi ukuxhotyiswa ngezibonakaliso zempendulo, i-limiters kunye neendawo zokubeka ukuhlangabezana neemfuno zokulawula ngokuzenzekelayo, ulawulo lweprogram okanye ukulungiswa kokuhamba.Umqondiso wengxelo yevalve ye-pneumatic diaphragm ithatha itekhnoloji yokuva i-non-contact.Imveliso ithatha i-membrane yohlobo lwe-cylinder ye-propulsion cylinder endaweni ye-piston cylinder, isusa ukungonakali komonakalo olula kwiringi yepiston, ebangela ukuvuza kunye nokungakwazi ukutyhala ivalve ukuba ivule kwaye ivale.Xa umthombo womoya ungaphumeleli, ivili lesandla lisenokusetyenziswa ukuvula nokuvala ivalve.
 
Umgaqo wokutywina wevalve ye-diaphragm kukuxhomekeka kwintshukumo ehlayo yendlela yokusebenza ukucinezela i-diaphragm okanye indibano ye-diaphragm kunye nomjelo womzimba wevalve yohlobo lwe-weir-throughthththththththththththththththththththththththththththththththththththththththni ivalve ukuphumeza itywina. .Uxinzelelo oluthile lwesitywina lufezekiswa ngoxinzelelo oluphantsi lwelungu lokuvala.Ekubeni umzimba wevalve unokufakwa kwizinto ezahlukeneyo ezithambileyo, ezifana nerabha okanye i-polytetrafluoroethylene, njl.;i-diaphragm nayo yenziwe ngezinto ezithambileyo, ezifana nerabha okanye irabha eyenziwe nge-polytetrafluoroethylene, ngoko inokufezekiswa ngamandla amancinci okutywinwa Ukutywinwa ngokupheleleyo.
 
Iivalvu ze-diaphragm zineenxalenye eziphambili ezintathu kuphela: umzimba, i-diaphragm kunye ne-bonnet assembly.I-diaphragm yahlula umngxuma ongaphakathi womzimba wevalvu esezantsi ukusuka kumngxuma ongaphakathi wesivalo sevalvu ephezulu, ukuze isiqu sevalve, isiqu sevalve, ivalve clack, indlela yokulawula umoya, indlela yokulawula umbane kunye nezinye iindawo ezibekwe ngaphezulu kwediaphragm. dibana nesiphakathi, kwaye akukho sidibaniso senziweyo.Ukuvuza kwangaphandle kusindisa isakhiwo sokutywinwa kwebhokisi yokufaka.
 
Apho isivalo se-diaphragm sisebenza khona
Ivalve ye-diaphragm luhlobo olukhethekileyo lwevalve yokuvala.Indawo yayo yokuvula neyokuvala yi-diaphragm eyenziwe ngezinto ezithambileyo, ezahlula umngxuma ongaphakathi womzimba wevalvu ukusuka kumngxuma ongaphakathi wesivalo sevalvu.
Ngenxa yokuthintelwa kwenkqubo yokufakwa kwevalvu yomzimba kunye nenkqubo yokwenziwa kwe-diaphragm, i-valve yomzimba omkhulu kunye nenkqubo yokwenziwa kwe-diaphragm enkulu kunzima.Ngoko ke, i-valve ye-diaphragm ayifanelekanga kwiidamitha ezinkulu zepayipi, kwaye isetyenziselwa imibhobho engaphantsi kwe-DN200.Indlela enye.
Ngenxa yokuncitshiswa kwezinto ze-diaphragm, i-valve ye-diaphragm ifanelekile kuxinzelelo oluphantsi kunye nezihlandlo zokushisa eziphantsi.Ngokuqhelekileyo musa ukudlula i-180°C.Ngenxa yokuba ivalve ye-diaphragm inomsebenzi olungileyo wokuchasana nomhlwa, isetyenziswa ngokubanzi kwizixhobo zemidiya ezonakalisayo kunye nemibhobho.Ngenxa yokuba ubushushu bokusebenza kwevalve ye-diaphragm bukhawulelwe yindlela esebenzayo ye-diaphragm valve body lining material kunye ne-diaphragm material.
 
Iimbonakalo:
(1) Ukuxhathisa ulwelo kuncinane.
(2) Ingasetyenziselwa indlela equlethe izinto eziqinileyo ezinqunyanyisiweyo;ekubeni i-medium iqhagamshelana kuphela nomzimba wevalve kunye ne-diaphragm, akukho mfuneko yebhokisi yokugxusha, akukho ngxaki yokufaka ukuvuza kwebhokisi, kwaye akukho nto inokwenzeka yokubola kwisiqu sevalve.
3
(4) Ayinakusetyenziswa kwiimeko zoxinzelelo oluphezulu.
 
Ukufakela nokugcina:
①Phambi kokufaka ivalve ye-diaphragm, jonga ngononophelo ukuba iimeko zokusebenza zombhobho ziyahambelana nomda wokusetyenziswa ochazwe yile valve, kwaye ucoce umngxuma ongaphakathi ukunqanda ubumdaka ekubambeni okanye ukonakalisa iindawo zokutywina.
②Musa ukusebenzisa igrisi okanye i-oyile kumphezulu womgca werabha kunye ne-diaphragm yerabha ukukhusela irabha ekudumbeni kwaye ichaphazele ubomi benkonzo yevalve ye-diaphragm.
③Ivili lesandla okanye indlela yokuhambisa ayivumelekanga ukuba isetyenziselwe ukuphakamisa, kwaye ukungqubana kuthintelwe ngokungqongqo.
④ Xa usebenzisa ngesandla ivalve ye-diaphragm, musa ukusebenzisa izincedisi ezincedisayo ukukhusela i-torque egqithisileyo ekonakaliseni amacandelo okuqhuba okanye iindawo zokutywina.
⑤Iivalve ze-diaphragm kufuneka zigcinwe kwigumbi elomileyo nelingena umoya, ukupakisha akuvumelekanga ngokungqongqo, iziphelo zombini zevalve yesitokhwe kufuneka zitywinwe, kwaye iindawo zokuvula kunye nokuvala kufuneka zibe kwindawo evuleke kancinci.
