Okokuqala, kutheni valve kabini ukutywina ayinakusetyenziswa njenge khangela ivalve?

Uncedo lwe khangela ivalve I-spool lulungelelwaniso lwamandla, ivumela umahluko omkhulu koxinzelelo, kunye nokungalunganga kwayo kukuba ezi ndawo zimbini zokutywina azinakunxibelelana ngokufanelekileyo ngaxeshanye, zikhokelela ekuvuza okukhulu. Ukuba yenziwe ngendlela eyiyo kwaye inyanzelwe ukusika izihlandlo, isiphumo ngokuqinisekileyo asilunganga, nokuba sele siphucule izinto ezininzi (ezinjengevaluva yomkhono etywiniweyo), ayinqweneleki.

Isibini, i-valve elawulayo kutheni umsebenzi wokuvula uvalo omncinci xa kulula ukuwukroba?

Isiseko esinye, xa uhlobo luhamba luhlobo oluvulekileyo, uzinzo lwevalve lulungile; Xa uhlobo luhamba luhlobo oluvaliweyo, uzinzo lwevalve luhlwempuzekile. Ivalve enezihlalo ezibini inee-spool ezimbini, i-spool esezantsi ivaliweyo, i-spool ephezulu ikukuvula evulekileyo, ukuze xa kuvulwa okuncinci kusebenza, ukuhamba kwe-spool kuvaliwe kulula ukubangela ukungcangcazela kwevalve, yeso sizathu sokuba isihlalo-mbini vana ayinakusetyenziselwa umsebenzi wokuvula omncinci.

Okwesithathu, yeyiphi into ethe ngqo yokuthintela ukusebenza kwevalve yokuthintela ukusebenza ayisiyongxaki, ukusebenza kwendlela yokuthintela i-Angle kulungile?

I-spool ye-valve ye-stroke eqondekileyo i-vertical throttling, kwaye i-medium ihamba ngokuthe tye kwaye iphuma, umjelo wokuhamba kwigumbi le-valve kufuneka ujike, ukwenzela ukuba indlela yokuhamba kwe-valve ibe nzima kakhulu (ukuma njengoluhlobo lwe-S). Ngale ndlela, mininzi imimandla efileyo, ebonelela ngendawo yokuthambeka, kwaye ekuhambeni kwexesha, kubangela ukucinywa. I-Angle stroke valve ye-throttling ulwalathiso lolwalathiso, ukuhamba ngokuthe tyaba kungena phakathi, ukuphuma okuthe tyaba, kulula ukuthatha indawo engcolileyo, ngaxeshanye indlela yokuhamba ilula, indawo yokuntywila kwemvula incinci kakhulu, ke ukubamba kwevalve yeAngle ukusebenza kulungile.

Zine. Kutheni le nto kunqunyulwe umahluko koxinzelelo lweI-valve yokubetha ye-Angle inkulu?

I-valve ye-Angle stroke enqunyulwe umahluko woxinzelelo inkulu, kuba iphakathi kwi ivelufa Isiseko okanye ipleyiti yevalve eveliswe ngamandla abangela ukujikeleza kwe-shaft torque incinci kakhulu, ke ngoko, inokumelana noxinzelelo olukhulu.

Zintlanu, kutheni ukubetha okuthe ngqo okulawula i-valve stem kunciphile?

Kubandakanya umgaqo olula woomatshini: ukungqubana okukhulu okushenxayo, ukungqubana okuncinci. Ukuhamba ngokuthe ngqo kwe-valve stem stem ukunyuka nokuhla, ukupakisha kancinci, kuya kubeka ipakethe ye-stem iqinile kakhulu, ibangele ukubuya okukhulu. Ukuza kuthi ga ngoku, isiqu sevalvethi senzelwe ukuba sincinci kakhulu, kwaye ukupakisha kuhlala kusetyenziswa umlinganiso omncinci wokukhuhlana wokupakisha i-tetrafluorine, ukwenzela ukunciphisa umahluko wokubuyela, kodwa ingxaki kukuba isiqu sibhityile, kulula ukugoba, kwaye ubomi bokupakisha bufutshane. Ukusombulula le ngxaki, eyona ndlela isebenzayo kukusebenzisa isiqu sevalve brigade, oko kukuthi, uhlobo lwe-Angle stroke ye-valve elawulayo, isiqu sayo kune-straight stroke stem thick thick 2 ~ 3 times, and use long life packing, stiffness is good , Ukupakisha ubomi kukude, i-torque yokukhuhlana incinci, umahluko wokubuya okuncinci.

Isithandathu, kutheni amanzi aphakathi asetyenziselwa ukusetyenziswa kwerabha ebhatyiweyo yebhabhathane, i-fluorine ene-diaphragm valve life life short?

Isidibanisi samanzi esiphakathi emanzini siqulathe uxinizelelo oluphantsi lweasidi okanye ialkali, eyonakalisa kakhulu irabha. Irabha umhlwa ngenxa yokwanda, ukwaluphala, amandla asezantsi, kunye nerabha yokufaka ibhabhathane ivelufa, uvalo isiphumo sokusetyenziswa kwevalufa sisiphumo sayo kukunganyangeki nokubola. Emva kokuba ivalile yerabha uvalo ivalve iphuculwe njengomhlwa olungileyo ukumelana ne-fluorine lining diaphragm valve, kodwa uvalo lwe-fluorine lining diaphragm valve ayikwazi ukumelana nokusonga okuphezulu nangaphantsi kwaye yaphukile, okukhokelela kumonakalo womatshini, ubomi bevalve bufutshane . Ngoku eyona ndlela ilungileyo yonyango lwamanzi olukhethekileyoivelufa yebholaInokusetyenziselwa i-5 ~ 8 iminyaka.

Sixhengxe. Kutheni le nto ivalve esikiweyo kufuneka itywinwe nzima kangangoko kunokwenzeka?

Okukhona ukuvuza okungaphantsi kuyafuneka ukusika ivalve, kokukhona kubangcono. Ukuvuza kwevalufa yokutywina ethambileyo yeyona iphantsi. Isiphumo sokusika ngokuqinisekileyo silungile, kodwa asiyonto inxibayo kwaye inokuthenjwa okungalunganga. Ukusuka kumgangatho ophindwe kabini wokuvuza okuncinci kunye nokutywina okuthembekileyo, itywina elithambileyo alikho njengelitywina elinzima. Njengomsebenzi opheleleyo wevalve yolawulo olukhanyayo, etywiniweyo kunye nokufakwa kukhuselo lwe-alloy enganyangekiyo, ukuthembeka okuphezulu, inqanaba lokuvuza kwe-10 ~ 7, ikwazile ukuhlangabezana neemfuno zevalve yokusika.
