I-Titanium B367 GC-2 Globe Valve
Kukho iintlobo ezi-3 zeendlela zokudibanisa: uxhulumaniso lwe-flange, uxhulumaniso lwentambo, kunye nokudibanisa kodwa-welding. Emva kokubonakala kweevalvu zokuzitywina, indlela yokuhamba ephakathi yevalve yokuvala iyatshintsha ukusuka ngentla kwediski yevalve ukuya kungena kwigumbi levalve. Ngeli xesha, phantsi koxinzelelo lwe-medium, i-force yokuvala i-valve incinci, ngelixa amandla okuvula i-valve inkulu, kwaye ububanzi be-valve ye-valve bunokuncitshiswa ngokufanayo. Ngexesha elifanayo, phantsi kwesenzo se-medium, le fomu yevalve nayo iqinile. "Iivalvu eziNtathu" zelizwe lethu zakha zachaza ukuba indlela yokuhamba kweevalvu zeglowubhu kufuneka ibe ukusuka phezulu ukuya ezantsi. Xa i-valve yokuvala ivuliwe, ukuphakama kokuvula kwediski ye-valve yi-25% ukuya kwi-30% ye-diameter ye-nominal. Xa umlinganiselo wokuhamba ufikelele kubuninzi bawo, kubonisa ukuba i-valve ifikelele kwindawo evulekile ngokupheleleyo. Ngoko indawo evuleke ngokupheleleyo yevalve yokuvala kufuneka imiselwe ngokubetha kwediski yevalve.
Indawo yokuvula neyokuvala yevalve yokumisa, iGlobe Valve, yidiskhi emile okweplagi, enendawo ethe tyaba okanye eyiconical kumphezulu wokutywina. Idiskhi yevalve ihamba ngomgca othe tye ecaleni kombindi wesitulo sevalve. Indlela yentshukumo yesikhondo sevalvu, eyaziwa ngokuba yintonga efihliweyo, ingasetyenziselwa ukulawula ukuhamba kweentlobo ezahlukeneyo zolwelo olunjengomoya, amanzi, umphunga, imithombo yeendaba eyonakalisayo, udaka, i-oyile, isinyithi solwelo, kunye nemithombo yeendaba ene-radioactive. ngokusebenzisa uhlobo lwentonga yokuphakamisa kunye nokujikeleza. Ngoko ke, olu hlobo lwevalve yokuvala lufaneleke kakhulu ukusika, ukulawula, kunye neenjongo zokubethelwa. Ngenxa yokuvula okanye ukuvala ukubetha okufutshane kwesiqu sevalve kunye nomsebenzi othembekileyo wokusikwa, kunye nobudlelwane obulinganayo phakathi kokutshintsha kwesitulo sevalve kunye nokubetha kwediski yevalve, olu hlobo lwevalve lubaluleke kakhulu. ilungele ukulawula ukuhamba.

Iimpawu ezongezelelweyo
Umgaqo-siseko wokusebenza kweevalve zeglobhu yentsimbi kukujikeleza ivalve ukwenza ivalve ingathinteleki okanye ivalwe. Iivalve zesango zikhaphukhaphu, zincinci ngobukhulu, kwaye zingenziwa zibe ngamadamitha amakhulu. Banokutywinwa okuthembekileyo, isakhiwo esilula, kunye nokugcinwa okufanelekileyo. Umphezulu wokutywina kunye nomphezulu ongqukuva uhlala ukwimeko evaliweyo kwaye awukhukuliseka lula ngamajelo eendaba. Zisetyenziswa kakhulu kumashishini ahlukeneyo.
Iperi yokutywina yevalve yokuvala ibandakanya umphezulu wokutywina wediski yevalve kunye nomphezulu wokutywina wesihlalo sevalve. Isiqu sevalve siqhuba idiski yevalve ukuba ihambe ngokuthe nkqo ecaleni kombindi wesitulo sevalve. Ngethuba lokuvula kunye nokuvala i-valve yokuvala, ukuphakama kokuvula kuncinci, okwenza kube lula ukulungelelanisa izinga lokuhamba, kwaye kulula ukuvelisa nokugcina, kunye noluhlu olubanzi lwezicelo zoxinzelelo.
Umphezulu wokutywina wevalve yeglowubhu ayinxibi okanye ikrweleke lula, kwaye akukho silawuli sihlobeneyo phakathi kwediski yevalve kunye nesihlalo sokutywinwa sesihlalo sevalve ngexesha lokuvula kunye nenkqubo yokuvala. Ngoko ke, ukunxiba kunye nokukrazula kwindawo yokutywina kuncinci, okuphucula ubomi benkonzo yesibini sokutywinwa. Ivalve yeglowubhu ine-valve disc stroke encinci kunye nobude obuncinci ngexesha lenkqubo yokuvala ngokupheleleyo. Ukungalungi kwe-valve yokuvala kukuba inokuvulwa okukhulu kunye nokuvala i-torque kwaye kunzima ukufezekisa ukuvulwa nokuvala ngokukhawuleza. Ngenxa yeendlela zokuqukuqela ezibuhlungu kumzimba wevalvu, ukuxhathisa kokuqukuqela kolwelo kuphezulu, okukhokelela kwilahleko enkulu yamandla olwelo kumbhobho.
Iimpawu zesakhiwo:
1. Vula kwaye uvale ngaphandle kokukhuhlana. Lo msebenzi usombulula ngokupheleleyo ingxaki yeevalvu zemveli ezichaphazela ukutywinwa ngenxa yokungqubana phakathi kweendawo zokutywina.
2. Isakhiwo esixhonywe phezulu. Iivalvu ezifakwe kwimibhobho zinokuhlolwa ngokuthe ngqo kwaye zilungiswe kwi-intanethi, enokunciphisa ngokufanelekileyo ixesha lokunciphisa isixhobo kunye neendleko eziphantsi.
3. Uyilo lwesihlalo esinye. Ukuphelisa ingxaki yokunyuka koxinzelelo olungaqhelekanga kwindawo yegumbi levalve, echaphazela ukhuseleko lokusetyenziswa.
4. Uyilo lwetorque ephantsi. Isiqu sevalve esinoyilo olukhethekileyo lwesakhiwo sinokuvulwa kwaye sivalwe ngokulula ngevalve yokubamba encinci.
5. Isakhiwo sokutywina esimilise okwe-Wedge. Iivalvu zixhomekeke kumandla omatshini obonelelwa sisikhondo sevalve ukucinezela i-wedge yebhola kwisihlalo sevalve kunye nokutywinwa, ukuqinisekisa ukuba ukusebenza kokutywina kwevalve akuchatshazelwa lutshintsho kumahluko woxinzelelo lombhobho, kunye nokusebenza okuthembekileyo kokutywinwa kuqinisekisiwe phantsi kokusebenza okuhlukeneyo. iimeko.
6. Isakhiwo sokuzicoca sendawo yokutywina. Xa ingqukuva ityekekela kude nesihlalo sevalvu, ulwelo olukumbhobho ludlula ngokufanayo kumphezulu wokutywina wengqukuva nge-engile ye-360 °, kungekuphela nje ukuphelisa ukukrwalwa kwendawo yesitulo sevalvu ngolwelo olunesantya esiphezulu, kodwa nokugungxulelwa kude. ukuqokelela kumphezulu wokutywina, ukufezekisa injongo yokuzicoca.
7. Imizimba ye-valve kunye nezigqubuthelo ezinobubanzi obungaphantsi kwe-DN50 ngamalungu abunjiweyo, ngelixa ezo ezinobubanzi obungaphezulu kwe-DN65 ziyinxalenye yentsimbi.
8. Iifom zoqhagamshelo phakathi komzimba wevalve kunye nesivalo sevalve zahlukile, kubandakanywa uqhagamshelo lwe-clamp pin shaft, uqhagamshelo lwe-gasket ye-flange, kunye noqhagamshelo lomsonto wokuzitywina.
9. Umphezulu wokutywina wesihlalo sevalve kunye nediski zonke zenziwe nge-plasma spray welding okanye i-overlay welding ye-cobalt chromium tungsten hard alloy. Imiphezulu yokutywina inobulukhuni obuphezulu, ukuxhathisa ukunxiba, ukuxhathisa ukonakala, kunye nobomi benkonzo ende.
10. Isixhobo sevalve yintsimbi ene-nitrided, kwaye ukuqina komphezulu kwesiqu sevalve ye-nitrided kuphezulu, ayigugi, iyamelana nokukrweleka, kwaye imelana nokudumba, kunye nobomi benkonzo ende.

Usetyenziso
Iivalvu zeglowubhu ye-Titanium ziphantse zangonakali emoyeni, emanzini amatsha, emanzini olwandle, kunye nomphunga wobushushu obuphezulu, kwaye ziyakwazi ukumelana nomhlwa kumajelo eendaba ealkaline. Iivalvu zeglowubhu ze-Titanium zinokumelana okuqinileyo ne-chloride ion kunye nokuxhathisa okugqwesileyo kwi-chloride ion corrosion. Iivalvu zeglowubhu ze-Titanium zinokuxhathisa okulungileyo kokutya kwimidiya efana ne-sodium hypochlorite, amanzi eklorini, kunye neoksijini emanzi. Ukunganyangeki kwe-corrosion ye-titanium globe valves kwi-organic acids kuxhomekeke ekunciphiseni okanye kwiipropati ze-oxidizing ze-asidi. Ukumelana nokutyiwa kweevalvu zeglowubhu ye-titanium ekunciphiseni ii-asidi kuxhomekeke kubukho be-corrosion inhibitors phakathi. Iivalvu zeglowubhu ye-Titanium zikhaphukhaphu kwaye zinamandla omatshini aphezulu, kwaye zisetyenziswa kakhulu kwi-aerospace. Iivalvu zeglowubhu ze-Titanium zinokuxhathisa ukhukuliseko lwemithombo yeendaba eyonakalisayo, kwaye inokusombulula ingxaki yomhlwa ekunzima ukuyisombulula kwimibhobho yothumelo lwemizi-mveliso enganyangekiyo kukonakala. Ineenzuzo zokhuseleko, ukuthembeka, kunye nobomi benkonzo ende. Isetyenziswa kakhulu kwishishini le-alkali ye-alkali, ishishini le-soda ash, ishishini lamayeza, ishishini lesichumisi, ishishini lemichiza elungileyo, i-textile fiber synthesis kunye neshishini lokudaya, i-asidi esisiseko ye-organic kunye nemveliso yetyuwa ye-inorganic, ishishini le-nitric acid, njl.
