✧ Inkcazo

Ivalve ye-SDV (iValve yokuvala iPhantsi) yivalve enembombo engu-V kwelinye icala le-spool yesiqingatha sebhola.Ngokulungelelanisa ukuvulwa kwe-spool, indawo enqamlezileyo ye-flow flow medium itshintshiwe ukulungelelanisa ukuhamba.Ingasetyenziselwa ulawulo lokutshintsha ukuqonda ukuvulwa okanye ukuvala umbhobho.Inomphumo wokuzicoca, unokufezekisa uhlengahlengiso oluncinci lokuhamba kwinqanaba elincinci lokuvula, umlinganiselo ohlengahlengiswayo mkhulu, ufanelekile kwifiber, iinqununu ezintle, i-slurry media.
Inxalenye yokuvula kunye nokuvala i-valve yebhola ye-V yi-sphere ene-circular channel, kwaye ii-hemispheres ezimbini zixhunywe nge-bolt kwaye zijikeleze i-90 ° ukufezekisa injongo yokuvula nokuvala.
Isetyenziswa ngokubanzi kwinkqubo yokulawula ngokuzenzekelayo yepetroleum, imboni yeekhemikhali njalo njalo.

✧ Iimpawu zevalve ye-SDV (iValve yokuvala) (i-V port)

1. ukuxhathisa ulwelo kuncinci, i-coefficient yokuhamba inkulu, i-adjustable ratio iphezulu.Inokufikelela ku: 100:1, enkulu kakhulu kunomlinganiselo ohlengahlengiswayo wevalve elawulayo yesihlalo esinye esithe tye, ivalve yokulawula izihlalo ezibini kunye nevalve yokulawula imikhono.Iimpawu zayo zokuhamba zimalunga nepesenti elinganayo.

2. ukutywinwa okuthembekileyo.Ibakala lokuvuza kwesakhiwo sesinyithi esiqinileyo sentsimbi yiKlasi IV ye-GB / T4213 "I-Pneumatic Control Valve".Ibakala lokuvuza kwesakhiwo setywina elithambileyo yiKlasi V okanye iKlasi VI ye-GB/T4213.Kwisakhiwo sokutywina esiqinileyo, umphezulu wokutywina ongundoqo webhola unokwenziwa nge-chromium eqinile, i-cobalt esekwe kwi-carbide esekwe ngesamente, ukutshiza i-tungsten carbide ukugquma ukunxiba, njl. njl., ukuphucula ubomi benkonzo yesitywina esingundoqo sevalve.

3. vula kwaye uvale ngokukhawuleza.I-valve yebhola ye-V yi-valve ye-angular stroke, ukusuka evulekile ngokupheleleyo ukuya kwi-spool evaliweyo ngokupheleleyo i-Angle 90 °, exhotyiswe nge-AT piston actuator pneumatic ingasetyenziselwa iimeko zokusika ngokukhawuleza.Emva kokufaka i-valve positioner yombane, inokulungelelaniswa ngokwe-analog signal 4-20Ma ratio.

4. ukusebenza kakuhle kokuthintela.I-spool ithatha i-1/4 ye-hemispherical shape ene-unilateral seat structure.Xa kukho amasuntswana aqinileyo phakathi, ukuvaleka komngxuma akuyi kwenzeka njengeevalve zebhola ze-O eziqhelekileyo.Akukho msantsa phakathi kwebhola ene-V kunye nesihlalo, esinamandla amakhulu okucheba, afanelekileyo ngokukhethekileyo ekulawuleni ukumiswa kunye neengqungquthela eziqinileyo ezinefiber okanye iincinci ezincinci eziqinileyo.Ukongezelela, kukho i-valve yebhola ye-V ene-spool yehlabathi, efanelekileyo ngakumbi kwiimeko zoxinzelelo oluphezulu kwaye inokunciphisa ngokufanelekileyo i-deformation ye-core yebhola xa ukwahlukana koxinzelelo oluphezulu lwenziwa.Yamkela isihlalo esinye sokutywinwa okanye isakhiwo sokutywina sesihlalo esiphindwe kabini.Ivalve yebhola ene-V ene-double seat seal isetyenziswa kakhulu kulawulo oluphakathi olucocekileyo, kwaye i-medium ene-particle ingabangela ingozi yokuvala umgodi ophakathi.

5. I-valve yebhola ye-V iyisakhiwo sebhola esisigxina, isihlalo silayishwe ngentwasahlobo, kwaye sinokuhamba kwindlela yokuhamba.Inokubuyisela ngokuzenzekelayo ukunxitywa kwe-spool, yandise ubomi benkonzo.Intwasahlobo ine-hexagonal spring, i-wave spring, i-disc spring, i-cylindrical compression spring njalo njalo.Xa i-medium inobumdaka obuncinci, kuyimfuneko yokongeza izindandatho zokutywina entwasahlobo ukuze zikhuseleke kwizinto ezingcolileyo.Kwizitulo eziphindwe kabini ezitywinwe iivalvu zebhola ze-spool ze-V, isakhiwo sebhola edadayo siyasetyenziswa.

6. xa kukho iimfuno zomlilo kunye ne-anti-static, i-valve core yenziwe ngesakhiwo sentsimbi eqinile, i-filler yenziwe ngegraphite eguquguqukayo kunye nezinye izinto ezichasene nobushushu obuphezulu, kwaye i-valve stem inegxalaba lokutywina.Thatha imilinganiselo ye-electrostatic conduction phakathi komzimba wevalvu, isiqu kunye nesphere.Ukuthobela i-GB/T26479 isakhiwo sokumelana nomlilo kunye ne-GB/T12237 iimfuno ze-antistatic.

7. I-valve yebhola ene-V ngokwendlela yokutywina ehlukeneyo ye-core yebhola, kukho i-zero eccentric structure, i-single eccentric structure, i-double eccentric structure, ezintathu ze-eccentric structure.Isakhiwo esisetyenziswa ngokuqhelekileyo ngu-zero eccentric.Isakhiwo se-eccentric sinokukhulula ngokukhawuleza i-spool kwisihlalo xa sivulwa, sinciphise ukunxiba kwendandatho yesitywina kunye nokwandisa ubomi benkonzo.Xa ivaliwe, amandla e-eccentric anokuveliswa ukwandisa isiphumo sokutywinwa.

8. Indlela yokuqhuba yevalve yebhola yohlobo lwe-V inohlobo lwe-handle, i-worm gear transmission, i-pneumatic, i-electric, i-hydraulic, i-electro-hydraulic linkage kunye nezinye iindlela zokuqhuba.

I-9.V-uhlobo lokudibanisa i-valve yebhola inonxibelelwano lwe-flange kunye nokudibanisa i-clamp iindlela ezimbini, kwi-spool yehlabathi, isakhiwo sokutywinwa kwesihlalo esiphindwe kabini kunye nokudibanisa intambo kunye ne-socket welding, i-butt welding kunye nezinye iindlela zokudibanisa.

I-10.ivalve yebhola ye-ceramic nayo ine-V-shaped ball core structure.Ukumelana nokunxiba okuhle, kodwa kunye nokuxhathisa kwe-asidi kunye ne-alkali, ilungele ngakumbi ulawulo lwemithombo yeendaba yegranular.Ivalve yebhola ene-fluorine ine-V-shaped ball core structure, esetyenziselwa ukulawula nokulawula i-asidi kunye ne-alkali media corrosive.Uluhlu lwesicelo se-valve yebhola ye-V ininzi kwaye ibanzi.
