Iimveliso
I-SDV Valve (ivaliwe i-valve)
✧ Inkcazo
Ivalve ye-SDV Ngokuhlengahlengisa ukuvulwa kweSpool, indawo enqamlezileyo yecandelo elihamba phambili itshintshiwe ukuba ihlengahlengise ukuhamba. Ingasetyenziselwa ukutshintsha ulawulo lokufezekisa ukuvula okanye ukuvala kombhobho. Ineziphumo zokuzicoca, inokufumana uhlengahlengiso oluncinci kuluhlu oluncinci lokuvula, umyinge oguqukayo yinto enkulu, ilungele ifayibha, amasuntswana amahle, amajelo eendaba.
Inxalenye yokuvula kunye nokuvala i-Vialve ye-V-Chetve yePhepha ye-Viep ejikeleze ijelo elijikelezayo, kwaye zombini i-hemispheres ixhunyiwe yi-bolt kwaye ijikeleze i-90 ° ukufezekisa injongo yokuvula nokuvalwa.
Isetyenziswe ngokubanzi kwinkqubo yokulawula ngokuzenzekelayo ye-petroleum, ishishini leekhemikhali njalo njalo.

Iimpawu ze-SDV Voveli (ivaliwe i-valve) (v port)
1. Ukunganyangeki kwe-fluid incinci, ukuhamba kwendlela yokuhamba kwayo kuyinto enkulu, umlinganiso oguqukayo uphakame. Ingafikelela: 100: 1, eninzi kakhulu kune-vati ohlengahlengiswayo yesihlalo esingatshatanga esithe ngqo, i-valve yesihlalo emibini kunye nevalve elawula. Iimpawu zayo zokuhamba zimalunga neepesenti ezilinganayo.
2. Ukutywinwa okuthembekileyo. Ibanga lokuvuza kwe-aKiakege ye-Foal Seal Seal I-CILY i-IV ye-GB / T4213 "i-valve yolawulo". Ibakala elivuzayo lendlela ethambileyo yeTywina yiklasi v okanye iklasi ye-vi ye-GB / T4213. Kwindawo enzima yokutywina, indawo engundoqo ephathwayo inokwenziwa nge-chromium ye-chromium enesidingo se-calbide, yokutshiza i-carbide ye-carbide ye-cartide, yokuphucula imeko yenkonzo ye-valve.
3. Vula kwaye usondele ngokukhawuleza. I-V-Chwethe i-valve yebhola ye-v-chell yivalve ye-angland ye-angland, ivulekile ngokupheleleyo kwi-Angle epheleleyo ye-Spool 90 Emva kokufaka isimilo sombane sombane, inokuhlengahlengiswa ngokomqondiso we-Analog 4-20ma.
I-4. Umsebenzi omnandi wokubhloka. I-spool yamkela imfazwe ye-1/4 ye-hemispherical enesakhiwo esihlalweni se-Unilateral. Xa kukho amasuntswana aqinileyo kwiphakathi, ibhlog ye-cavity ayiyi kwenzeka njenge Valves zeBhola ye-O). Akukho bhanti phakathi kwebhola ye-V-ene-v kunye nesihlalo, enamachiza amakhulu, ngakumbi ifanelekile kulawulo lokumiswa kunye namasuntswana aqinileyo ane-fiber okanye amasuntswana aphantsi aqukethe i-fiber okanye amasuntswana aphezulu ane-fiber okanye amasuntswana amancinci ane-fiber okanye amasuntswana amancinci ane-fiber okanye amasuntswana aphantsi aqukethe i-fiber okanye amasuntswana aphantsi aqukethe i-fiber okanye amasuntswana ane-fiber. Ukongeza, kukho i-valves yebhola ye-V-ene-v-valves ene-prool yehlabathi, ezilungele iimeko eziphezulu zoxinzelelo kwaye zinokunciphisa ngokufanelekileyo ukungcungcutheka kwebhola ekhatywayo xa kwenziwa uxinzelelo oluphezulu. I-IT yamkela indawo yokutywina kwesihlalo okanye indawo yokutywina kabini. Ivalve ye-v-valve ene-will enetywina eliphindwe kabini lisetyenziselwa umgaqo-nkqubo ococekileyo ococekileyo, kwaye ophakathi ngamasuntswana lunokubangela ingozi yokuvala ingozi.
I-5. Uhlobo lwe-v-call i-valve yebhola yebhola, isitulo silayishwe ngentwasahlobo, kwaye inokuhamba kwindlela yokuhamba. Unokuhlawula ngokuzenzekelayo i-Spool Spool, yandisa ubomi benkonzo. Intwasahlobo inentwasahlobo ye-hexagonal yase-Hexagonal, i-wave isples, i-disc, i-disc, i-cylindrical yoxinzelelo. Xa i-Medium ingcoliseko imnandi, kubalulekile ukongeza amakhonkco okutywina ukuya entwasahlobo ukuze ayikhusele ekungcoleni. Ngeendawo zokuhlala kabini ezitywiniweyo zeSpools zeHlabathi ye-vsves, ibhola yebhola edadayo isetyenziswa.
6. Xa kukho iimfuno zomlilo kunye neemfuno ezinqabileyo, i-valve yenziwa nge-bilt yokutywina, i-filter yenziwa ngegrafu eguquguqukayo kunye nezinye izinto zobushushu obuphezulu, kwaye i-valve inamagxa. Thatha amanyathelo okuphucula i-elektrostatic phakathi komzimba wevalve, stem kunye nendawo. Ukuthobela i-GB / T26479 Isakhiwo esinganyangekiyo soMlilo kunye ne-GB / T12237 iimfuno ze-antisttic.
I-7. I-V-Voliped Ball ivalve ngokwesakhiwo esahlukileyo sokutywina kwebhola esiphambili, kukho ulwakhiwo lwe-zeroccentric, ubume be-eccentric, ubume obuphindwe kabini, ubume obuphindwe kabini. Ulwakhiwo oluqhelekileyo lusetyenziswa yi-zeroccentric. Ulwakhiwo lwe-eccentric lunokukhulula ngokukhawuleza i-spool ukusuka esihlalweni xa kuvuliwe, ukunciphisa ukunxibisa i-teali ring kwaye kwandise ubomi beenkonzo. Xa ivaliwe, amandla e-eccentric anokuveliswa ukuphucula isiphumo sokutywina.
I-8. Indlela yokuqhuba yeVolve ye-V-Chwetheli ye-V-Chwetheza i-Chea, iPneumatic, yoMoya, i-hydraulic, i-Eledro-Hydraulic conces.
I-9.V-Chwetheza i-Blovel Valve inonxibelelwano lweflonge kwaye iqhagamshele iindlela ezimbini, kwiSpool yeHlabathi, indawo yokutywina kabini, uqhagamshelo lwe-sulvel kunye ne-subling kunye nezinye iindlela zonxibelelwano.
I-valve yebhola ye-10.Coramic ineendawo ezinolwakhiwo lwebhola. Ukunganyangeki okuhle, kodwa kunye ne-acid kunye ne-alkali corrosion, ilungele ngakumbi ukulawula imithombo yeendaba yaseburhulumenteni. I-Fluorine Linder Ivalve i-valve inesimo esibuhlungu se-V-esinebhotile, esisetyenziselwa ukulawula kunye nokulawula i-Acid kunye ne-Alkali Couviedition. Uluhlu lwesicelo lweValve yebhola ye-V
Inkonzo yokuthengisa emva kwentengiso
Inkonzo yasemva kwentengiso yeValve ye-SDV (ivaliwe i-valve) (v port) ibaluleke kakhulu, kuba kuphela inkonzo yexesha elifanelekileyo kwaye isebenza emva kwentengiso inokuqinisekisa ukusebenza kwalo ixesha elide kunye nokusebenza. Oku kulandelayo yimixholo yenkonzo yasemva kwentengiso ye-valve edadayo:
1.Ukulawula kunye nokuyalela: Abasebenzi beenkonzo zentengiso emva kwentengiso baya kuya kwindawo yokufaka kunye nokugxotha ivali yokuqhubela phambili ivali yokuqinisekisa ukuzinza kwayo kunye okuqhelekileyo.
Ukuphathwa komhlaba: Gcina rhoqo ivali yokudada ukuqinisekisa ukuba yeyeyona meko isebenzayo kwaye inciphise ireyithi yokusilela.
3.Ukuzimela: Ukuba ivalva yokudada iyasilela, abasebenzi beenkonzo zentengiso emva kwentengiso baya kwenza ukungafikeleli kwi-Stemsshoouset ngexesha elifutshane kakhulu ukuqinisekisa ukusebenza kwayo.
4. Ukuhlaziya uhlaziyo kunye nokuphuculwa: Ukuphendula kwezinto ezintsha kunye netekhnoloji entsha ephuma kwimarike, ekuseni yabasebenzi baya kuncoma ngokukhawuleza ukuhlaziya kunye nokuhlaziya izisombululo ezingcono.
5. Uqeqesho loLwazi: Abasebenzi beenkonzo zentengiso emva kwentengiso baya kubonelela ngoqeqesho lolwazi oluhleliweyo kubasebenzisi ukuphucula inqanaba lolawulo kunye nelondolozo lwabasebenzisi besebenzisa ivali yebhola. Ngamafutshane, inkonzo yasemva kwentengiso ye-valve yokudada yebhola kufuneka iqinisekiswe kuzo zonke iindlela. Kuphela ngale ndlela kuphela ingazisa abasebenzisi amava angcono kwaye athenge ukhuseleko.
