Umehluko phakathi kwe-valve yebhola yohlobo lwe-O kanye ne-valve yebhola yohlobo lwe-V.

I-valve yebhola

Kunezinhlobo eziningi zezakhiwo zama-valve ebhola, kodwa ziyafana.Wonke angama-ball cores okuvula nawokuvala kuyindilinga.Ikakhulukazi yakhiwe isihlalo se-valve, i-sphere, indandatho yokuvala uphawu, isiqu se-valve nezinye izinto zokushayela.Isiqu se-valve sizungezisa amadigri angu-90 ukuze kuzuzwe Ukuvuleka nokuvalwa kwe-valve kusetshenziswa epayipini ukuvala, ukusabalalisa, ukulungisa izinga lokugeleza kanye nokushintsha isiqondiso sokugeleza kwendawo ephakathi.Isihlalo se-valve sisebenzisa amafomu ahlukene okuvala izihlalo kuye ngezimo zokusebenza ezihlukene.Ngaphakathi komzimba we-valve we-valve yebhola yohlobo lwe-O iyindilinga enembobo emaphakathi.Imbulunga inembobo edlulayo enobubanzi obulingana nobubanzi bepayipi.I-sphere ingazungeza esihlalweni sokuvala.umzimba ukuze ufinyelele ukubekwa uphawu.Umgogodla webhola we-valve yebhola yohlobo lwe-V unesakhiwo esimise okwe-V.I-valve core iyigobolondo eliyindilinga elingu-1/4 elinenotshi emise okuka-V.Inomthamo omkhulu wokugeleza, ububanzi obukhulu obulungisekayo, amandla okugunda, nokuvala okuqinile.Impahla enezimo ze-fibrous.

I-valve yebhola yohlobo lwe-O:

Ngaphakathi komzimba we-valve we-valve yebhola yohlobo lwe-O iyindilinga enembobo emaphakathi.Imbulunga inembobo edlulayo enobubanzi obulingana nobubanzi bepayipi.I-sphere ingazungeza esihlalweni sokuvala.umzimba ukuze ufinyelele ukubekwa uphawu.Ngokuzungezisa ibhola ngo-90 °, isiqondiso sembobo singashintshwa, ngaleyo ndlela siqaphele ukuvulwa nokuvala kwe-valve yebhola.I-valve yebhola yohlobo lwe-O yamukela umklamo ontantayo noma ongaguquki, futhi izingxenye ezihambayo ezihambisanayo zenziwe ngezinto zokuzigcoba nge-coefficient encane kakhulu ye-friction, ngakho-ke i-torque yokusebenza incane.Ngaphezu kwalokho, ukuvalwa kwesikhathi eside kwegrisi yokuvala kwenza umsebenzi ube nezimo.Izinzuzo zomkhiqizo zimi kanje:

I-valve yebhola engu-1.O inokumelana noketshezi oluphansi

Ama-valve ebhola ngokuvamile anezakhiwo ezimbili ezinobubanzi nobubanzi obuncishisiwe.Kungakhathaliseki ukuthi yisiphi isakhiwo, i-coefficient yokumelana nokugeleza kwe-valve yebhola incane kakhulu.I-valve yebhola evamile iwuhlobo oluqondile, owaziwa nangokuthi i-valve yebhola yohlobo olugcwele.Ububanzi besiteshi bulingana nobubanzi obungaphakathi bepayipi, futhi ukulahlekelwa kokumelana kuphela ukumelana nokungqubuzana kwepayipi yobude obufanayo.Kuwo wonke ama-valve, le valvu yebhola inokumelana okuncane noketshezi.Kunezindlela ezimbili zokunciphisa ukumelana kwesistimu yamapayipi: enye iwukunciphisa izinga lokugeleza kwamanzi ngokwandisa ububanzi bepayipi kanye ne-valve, okuzokwandisa kakhulu izindleko zesistimu yamapayipi.Okwesibili ukunciphisa ukumelana kwendawo kwe-valve, futhi i-valve yebhola iyona engcono kakhulu.

Ukushintsha kwe-valve yebhola engu-2.O kuyashesha futhi kulula

I-valve yebhola idinga kuphela ukuphendukiswa ngo-90° ukuze kuqedelwe ukuvuleka okugcwele noma ukuvala ngokugcwele, ukuze ivuleke futhi ivalwe ngokushesha.

3. I-valve yebhola yohlobo lwe-O inomsebenzi omuhle wokuvala uphawu

Iningi lezihlalo zamavalvu ebhola zenziwe ngezinto ezinwebekayo ezifana ne-PTFE, evamise ukubizwa ngamavalvu ebhola ane-soft-sealed.I-valve yebhola evalwe ngokuthambile inokusebenza okuhle kokuvala, futhi izidingo zokuqina nokunemba komshini wendawo yokuvala ye-valve aziphezulu kakhulu.

4. I-valve yebhola yohlobo lwe-O inesikhathi eside senkonzo

Ngenxa yezakhiwo ezinhle zokuzigcoba ze-PTFE noma i-F4, i-coefficient yokungqubuzana ne-sphere incane.Ngenxa yobuchwepheshe bokucubungula obuthuthukisiwe, ukuqina kwebhola kuyancipha, ngaleyo ndlela kuthuthukisa kakhulu impilo yesevisi ye-valve yebhola.

5. I-valve yebhola ye-O inokwethenjelwa okuphezulu

I-pair of sealing pairs phakathi kwebhola nesihlalo se-valve ngeke ihlupheke ngemihuzuko, ukuguga okusheshayo nokunye ukwehluleka;

Ngemuva kokuthi isiqu se-valve sishintshelwe ohlotsheni olwakhelwe ngaphakathi, ingozi yengozi efihliwe ukuthi isiqu se-valve singase siphume ngenxa yokukhululeka kwe-gland yokupakisha ngaphansi kwesenzo sokucindezela kwamanzi kuyaqedwa;

I-valve yebhola ene-anti-static kanye nesakhiwo esikwazi ukumelana nomlilo ingasetshenziselwa amapayipi okuthutha uwoyela, igesi yemvelo kanye negesi. I-valve engumgogodla (ibhola) yohlobo lwe-O-valve yebhola iyindilinga.Ngokombono wesakhiwo, isihlalo se-valve yebhola sishunyekwa ohlangothini lwesihlalo se-valve yomzimba we-valve ngesikhathi sokuvalwa.Izingxenye ezihambayo ezihambisanayo zenziwe ngezinto zokuzigcoba nge-coefficient encane kakhulu ye-friction, ngakho-ke i-torque yokusebenza incane.Ngaphezu kwalokho, ukuvalwa kwesikhathi eside kwegrisi yokuvala kwenza umsebenzi ube nezimo.Ngokuvamile kusetshenziselwa ukulungiswa kwezindawo ezimbili, isici sokugeleza sivula ngokushesha.Lapho i-valve yebhola yohlobo lwe-O ivuliwe ngokugcwele, izinhlangothi ezimbili azivimbeli, zakha umgudu wepayipi oqondile, ovalwe ngendlela emibili, ofanele izikhathi zokunqunywa kwezikhundla ezimbili okuyimidiya engcolile futhi ene-fibrous.I-ball core ihlale ikhiqiza ukungqubuzana ne-valve ngesikhathi sokuvula nokuvalwa kwe-valve.Ngasikhathi sinye, ukuvala phakathi kwe-valve core kanye nesihlalo se-valve kufinyelelwa ngamandla okuvala i-pee-tightening yesihlalo se-valve ngokumelene nomgogodla webhola, kodwa ngenxa yesihlalo se-valve esithambile, izakhiwo ezinhle kakhulu zemishini nezomzimba zikwenza kube kuhle. ivaliwe.

I-valve yebhola yohlobo lwe-V

Umgogodla webhola we-valve yebhola yohlobo lwe-V unesakhiwo esimise okwe-V.I-valve core iyigobolondo eliyindilinga elingu-1/4 elinenotshi emise okuka-V.Inomthamo omkhulu wokugeleza, ububanzi obukhulu obulungisekayo, amandla okugunda, nokuvala okuqinile.Impahla enezimo ze-fibrous.Ngokuvamile, ama-valve ebhola ohlobo lwe-V angama-valve ebhola avaliwe.Ayilungele ukusetshenziswa kabili.

Umphetho omise okwe-V, unqamule ukungcola.Ngesikhathi sokujikeleza kwebhola, unqenqema lommese omise okwe-V webhola lunamathele esihlalweni se-valve, ngaleyo ndlela inqamule imicu kanye nezinto eziqinile oketshezini, kuyilapho i-valve yebhola jikelele ingenawo lo msebenzi, ngakho-ke kulula. ukubangela ukuthi ukungcola kwefiber kubambeke lapho kuvalwa, okudingekayo ukuze kugcinwe futhi kulungiswe.Ukunakekela kuletha ukuphazamiseka okukhulu.I-spool ye-valve yebhola yohlobo lwe-V ngeke ibambelele ku-fiber.Ngaphezu kwalokho, ngenxa yokusetshenziswa kokuxhumeka kwe-flange, kulula ukuhlakaza nokuhlanganisa, akukho mathuluzi akhethekile adingekayo, nokugcinwa kulula.lapho i-valve ivaliwe.Kunomphumela wesikelo esimise okwe-wedge phakathi kwenotshi emise okuka-V kanye nesihlalo sevalvu, esingagcini nje ngokuba nomsebenzi wokuzihlanza kodwa futhi esivimbela ukuthi ibhola libhajwe.I-Stem spring, ngakho-ke, i-torque yokusebenza incane futhi izinzile kakhulu.

I-valve yebhola emise okwe-V iyisakhiwo sokuzungezisa se-engeli yesokudla, esingaqaphela ukulawulwa kokugeleza.Ingakwazi ukufinyelela amazinga ahlukene okulinganisa ngokuya nge-engeli emise okwe-V yebhola elimise okwe-V.Amavalvu ebhola amise okwe-V ngokuvamile asetshenziswa ngokuhambisana nama-actuator nama-positioners ukuze kuzuzwe ukulungiswa ngokulinganayo.I-valve ewumgogodla emise okwe-V ifaneleka kakhulu ezikhathini zokulungiswa okuhlukahlukene, ene-coefficient enkulu yokugeleza kukalwe, isilinganiso esikhulu esilungisekayo, umphumela omuhle wokuvala, ukusebenza kokulungisa okungenazwelo ku-zero, usayizi omncane, futhi ingafakwa ngokuqondile.Ifanele ukulawula igesi, umusi, uketshezi kanye neminye imidiya.I-valve yebhola yohlobo lwe-V iyisakhiwo esijikelezayo se-right-angle, esihlanganisa umzimba we-valve wohlobo lwe-V, i-actuator yomoya, i-positioner nezinye izesekeli;inesici sokugeleza esingokwemvelo cishe samaphesenti alinganayo;yamukela isakhiwo esinezinhlangothi ezimbili, ene-torque yokuqala ephansi nokusebenza okuhle kakhulu.Ukuzwela kanye nesivinini sokungeniswa, ikhono lokugunda kakhulu.
