✧ Inkcazo

Ivalvu ye-SDV (iValve yokuvala) yivalvu enomngxuma ofana no-V kwelinye icala lespool yesiqingatha sebhola. Ngokulungisa umngxuma wespool, indawo enqamlezileyo yomngxuma ophakathi iyatshintshwa ukuze kulungiswe umngxuma. Ingasetyenziselwa nolawulo lokutshintsha ukuze kufezekiswe ukuvulwa okanye ukuvalwa kombhobho. Inesiphumo sokuzicoca, inokufezekisa uhlengahlengiso oluncinci lomngxuma kuluhlu oluncinci lokuvula, umlinganiselo ohlengahlengiswayo mkhulu, ufanelekile kwifayibha, amasuntswana amancinci, imidiya yeslurry.
Inxalenye yokuvula nokuvala yevalvu yebhola yohlobo lwe-V yingqukuva enetshaneli ejikelezayo, kwaye ezi hemispheres zimbini ziqhagamshelwe ngebholiti kwaye zijikeleza ngama-90° ukufezekisa injongo yokuvula nokuvala.
Isetyenziswa kakhulu kwinkqubo yolawulo oluzenzekelayo lwepetroliyam, imboni yeekhemikhali njalo njalo.

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

1. Ukumelana kolwelo kuncinci, i-flow coefficient inkulu, umlinganiselo ohlengahlengiswayo uphezulu. Ungafikelela kwi-:100:1, enkulu kakhulu kunomlinganiselo ohlengahlengiswayo wevalvu elawulayo yesihlalo esinye ethe tye, ivalvu elawulayo yezihlalo ezimbini kunye nevalvu elawulayo yesleeve. Iimpawu zayo zokuhamba zimalunga nepesenti efanayo.

2. utywino oluthembekileyo. Udidi lokuvuza kwesakhiwo setywino esiqinileyo sesinyithi yiKlasi IV ye-GB/T4213 "iValve yoLawulo lwePneumatic". Udidi lokuvuza kwesakhiwo setywino esithambileyo yiKlasi V okanye iKlasi VI ye-GB/T4213. Kwisakhiwo setywino esiqinileyo, umphezulu wetywino we-ball core ungenziwa nge-hard chromium plating, i-surfacing cobalt based cemented carbide, i-spraying tungsten carbide resistant wear coating, njl.njl., ukuphucula ubomi benkonzo yetywino esiqinileyo sevalvu.

3. vula kwaye uvale ngokukhawuleza. Ivalvu yebhola yohlobo lwe-V yivalvu ye-angular stroke, ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo. I-Angle 90°, exhotyiswe nge-AT piston pneumatic actuator ingasetyenziselwa iimeko zokusika ngokukhawuleza. Emva kokufaka i-electric valve positioner, ingalungiswa ngokwe-analog signal 4-20Ma ratio.

4. ukusebenza kakuhle kokuvimba. I-spool isebenzisa i-1/4 yesimo se-hemispherical enesakhiwo sesihlalo esicalanye. Xa kukho amasuntswana aqinileyo kwindawo ephakathi, ukuvaleka kwe-cavity akuyi kwenzeka njengeevalvu zebhola eziqhelekileyo ze-O. Akukho msantsa phakathi kwebhola enomfanekiso we-V kunye nesihlalo, esinamandla amakhulu okucheba, afanelekileyo ngakumbi kulawulo lwe-suspension kunye namasuntswana aqinileyo aqulethe i-fiber okanye amasuntswana amancinci aqinileyo. Ukongeza, kukho iivalvu zebhola ezinomfanekiso we-V ezine-global spool, ezifanelekileyo ngakumbi kwiimeko zoxinzelelo oluphezulu kwaye zinokunciphisa ngokufanelekileyo ukuguqulwa kwe-ball core xa kusenziwa umahluko woxinzelelo oluphezulu. Isebenzisa ukuvalwa kwesihlalo esinye okanye isakhiwo sokuvalwa kwesihlalo esiphindwe kabini. Ivalvu yebhola enomfanekiso we-V ene-double seat seat isetyenziswa kakhulu kulawulo lokuhamba okucocekileyo okuphakathi, kwaye i-medium ene-particles inokubangela ingozi yokuvala i-cavity ephakathi.

5. Ivalvu yebhola yohlobo lwe-V yisakhiwo sebhola esizinzileyo, isihlalo sigcwele intwasahlobo, kwaye sinokuhamba ngendlela yokuhamba. Ingabuyisela ngokuzenzekelayo ukuguguleka kwespool, yandise ubomi benkonzo. Intwasahlobo inentwasahlobo enesiqingatha, intwasahlobo yamaza, intwasahlobo yediski, intwasahlobo yoxinzelelo oluyi-cylindrical njalo njalo. Xa i-medium inokungcola okuncinci, kuyimfuneko ukongeza amaringi okuvala kwintwasahlobo ukuze uyikhusele ekungcoleni. Kwiivalvu zebhola zebhola ze-V ezitywiniweyo zezihlalo ezimbini, kusetyenziswa isakhiwo sebhola esintantayo.

6. xa kukho iimfuno zomlilo kunye nezokulwa nokungashukumi, umongo wevalvu wenziwe ngesakhiwo sentsimbi esiqinileyo, isizalisi senziwe ngegrafiti eguquguqukayo kunye nezinye izinto ezimelana nobushushu obuphezulu, kwaye isiqu sevalvu sinegxalaba lokutywina. Thatha amanyathelo okuqhuba ngombane phakathi komzimba wevalvu, isiqu kunye nesphere. Thobela isakhiwo esingashukumiyo somlilo se-GB/T26479 kunye neemfuno zokungashukumi ze-GB/T12237.

7. Ivalvu yebhola enomfanekiso we-V ngokwesakhiwo sokutywina esahlukileyo se-ball core, akukho sakhiwo singaqhelekanga, isakhiwo esinye esingaqhelekanga, isakhiwo esiphindwe kabini esingaqhelekanga, isakhiwo esingaqhelekanga esithathu. Isakhiwo esisetyenziswa rhoqo asiqhelekanga. Isakhiwo esingaqhelekanga sinokukhulula ngokukhawuleza i-spool kwisihlalo xa sivuliwe, sinciphise ukuguguleka kweringi yokutywina kwaye sandise ubomi benkonzo. Xa ivaliwe, amandla angaqhelekanga anokuveliswa ukuphucula isiphumo sokutywina.

8. Indlela yokuqhuba yevalvu yebhola yohlobo lwe-V inohlobo lwesibambo, uthumelo lwegiya le-worm, i-pneumatic, umbane, i-hydraulic, i-electro-hydraulic linkage kunye nezinye iindlela zokuqhuba.

Uqhagamshelo lwevalvu yebhola yohlobo lwe-9.V lunoqhagamshelo lweflange kunye noqhagamshelo lweclamp ngeendlela ezimbini, ze-global spool, isakhiwo sokutywina izihlalo ezimbini kunye noqhagamshelo lwentambo kunye ne-socket welding, i-butt welding kunye nezinye iindlela zoqhagamshelo.

10. Ivalvu yebhola yeseramikhi ikwanayo nesakhiwo sesiseko sebhola esimile okwe-V. Iyakwazi ukumelana nokuguguleka kakuhle, kodwa ikwakwazi ukumelana nokugqwala kwe-asidi kunye ne-alkali, ifaneleke ngakumbi kulawulo lwe-granular media. Ivalvu yebhola enee-fluorine ene-fluorine ikwanayo nesakhiwo sesiseko sebhola esimile okwe-V, esisetyenziselwa ukulawula nokulawula i-acid kunye ne-alkali media egqwalisayo. Uluhlu lokusetyenziswa kwevalvu yebhola yohlobo lwe-V lubanzi ngakumbi.
