Globe mavharuvhu, gedhi mavharuvhu, shavishavi mavharuvhu, cheki mavharuvhu uye bhora mavharuvhu zvose zvinokosha kudzora zvinoriumba mune siyana pombi masisitimu nhasi. Vhuru yega yega yakasiyana muchitarisiko, chimiro uye kunyange kushanda kushanda. Nekudaro, iyo globe valve uye gedhi vharafu zvine zvimwe zvakafanana pakuonekwa, uye panguva imwechete ine basa rekucheka mupombi, saka pachava neshamwari dzakawanda dzisingabatanidzi zvakanyanya nevhavha kuti dzivhiringidze izvo zviviri. Muchokwadi, kana iwe ukanyatsotarisisa, mutsauko uripo pakati pevharuvhu yepasi uye gedhi vharuvhu uchiri wakakura.
- Chimiro
Kana iri nzvimbo shoma yekuisa, zvinofanirwa kutarisisa kusarudzwa kwe:
Ivhavha yegedhi inogona kuvharwa zvakasimba nepamusoro pekuvhara nekuvimba nepakati pekumanikidza, kuitira kuti uwane mhedzisiro yekusadonha. Pakuvhura nekuvhara, spool yevhavha uye chigaro chekuvhara chigaro chevhavha chinogara chakabatana uye chichikwizana kune mumwe nemumwe, saka nzvimbo yekuisa chisimbiso iri nyore kupfeka, uye kana vharanda regedhi rave pedyo nekuvhara, mutsauko wepakati pakati pemberi uye kumashure kwepombi yakakura kwazvo, zvichiita kuti chisimbiso chepamusoro chipfeke zvakanyanya.
Chimiro chevhavha yegedhi chichave chakanyanya kuoma kupfuura chivharo chepasi, kubva pakuonekwa kwemaonero, munyaya ye caliber yakafanana, gedhi regedhi rakakwirira kudarika vheji yepasi, uye vheji yepasi yakareba kupfuura yevhavha yegedhi. Mukuwedzera, gedhi regedhi rakakamurwa kuva tsvimbo yakajeka uye tsvimbo yakasviba. The globe valve haisi.
- Basa
Kana iyo globe valve yakavhurwa uye yakavharwa, imhando yedzinde inosimuka, kureva kuti, vhiri reruoko rinotenderedzwa, uye vhiri reruoko rinoita kutenderera uye kusimudza mafambiro pamwe nevhavha stem. Ivhavha yegedhi ndeyekushandura handwheel, kuitira kuti tsinde iite kufamba kwekusimudza, uye nzvimbo yehandwheel pachayo inoramba isina kuchinja.
Kuyerera kwemitengo inosiyana, ine mavharuvhu egedhi anoda kuvharwa kwakazara kana kuzara, nepo mavharuvhu eglobhu asingadaro. Iyo vharuvhu yepasirese ine yakatsanangurwa yekupinda uye yekubuda nzira, uye vheji yegedhi haina kupinza uye kutumira kunze kwekutungamira zvinodiwa.
Mukuwedzera, gedhi regedhi rinongozaruka zvakakwana kana kuti rakavharwa zvakakwana nyika mbiri, gedhi rekuzarura nekuvhara kwekurohwa kwakakura kwazvo, nguva yekuzarura nekuvhara yakareba. Iyo valve plate yekufamba sitiroko yevharuvhu idiki zvakanyanya, uye vharafu yevharuvhu yevharuvhu inogona kumira pane imwe nzvimbo ichifamba yekugadzirisa kuyerera. Ivhavhavha yegedhi inogona kungoshandiswa kudzikisa uye haina rimwe basa.
- Performance
Iyo globe valve inogona kushandiswa truncation uye kuyerera mutemo. Kupikiswa kwemvura kwevharuvhu yeglobe kwakakura, uye kunonetsa kuvhura nekuvhara, asi nekuti ndiro yevharuvhu ipfupi kubva panzvimbo yekuvharisa, kuvhura nekuvhara sitiroko ipfupi.
Nemhaka yokuti vheji yegedhi inogona kungove yakazaruka zvakakwana uye yakavharwa zvakakwana, kana yakazarurwa zvakakwana, kushorwa kwekuyerera kwepakati mukati mevhavha yemuviri wegeji inenge inenge 0, saka kuzarura nekuvhara kwevhavha yegedhi kuchave kwakanyanya kushanda-kuchengetedza, asi ndiro yegedhi iri kure nepamusoro pekuvhara, uye nguva yekuzarura nekuvhara yakareba.
- Kuiswa uye nzira yekuyerera
Mhedzisiro yevhavha yegedhi inoyerera mumativi ese akafanana, uye hapana chinodiwa chekupinda nekubuda nzira yekuisirwa, uye yepakati inogona kuyerera mumativi ese. Ivhavhavhavhavhavhavhavhavhuvhu rinoda kuiswa zvakanyatsoenderana negwara rechiratidzo chemuseve wemuviri wevharuvhu, uye pane chirevo chakajeka pamusoro pegwaro rekutumira nekutumira kunze kwevharuvhu, uye mafambiro evharuvhu repasi "matatu kuenda" kuChina kubva kumusoro kusvika pasi.
Iyo globe valve yakaderera mukati uye yakakwira kunze, uye kubva kunze kune mapaipi akajeka asiri padanho rechikamu. Mumhanyi wevharuvhu wegedhi ari pamutsetse wakachinjika. Kurova kwevharuvhu yegedhi yakakura kupfuura iyo yevharuvhu yepasi.
Kubva pakuona kwekuyerera kwekudzivirira, kuyerera kwevhavha yegedhi kuduku kana yakazaruka zvakakwana, uye kuyerera kwekudzivirira kwevhavha yekumisa mutoro yakakura. Iyo inoyerera inopikisa coefficient yeyakajairwa gedhi vharafu inenge 0.08 ~ 0.12, kuvhura uye kuvhara simba idiki, uye yepakati inogona kuyerera munzira mbiri. Kuyerera kwekupokana kweakajairwa-kuvhara mavharuvhu ndeye 3-5 nguva iyo yegedhi mavharuvhu. Kana uchivhura nekuvhara, zvakakosha kumanikidza kuvharika kuti uwane chisimbiso, iyo valve spool yeglobe valve inongosangana neyekuvharisa pamusoro kana yakavharwa zvachose, saka kupfeka kweiyo yekuisa chisimbiso kudiki kwazvo, nekuti kuyerera kwesimba guru rinoda kuwedzera actuator Yevhavhavha yepasi rose inofanirwa kuterera kune torque control mechanism kugadzirisa.
Ivhavha yevhu ine nzira mbiri dzekuisa, imwe ndeyokuti yepakati inogona kupinda kubva pasi pevhavha spool, iyo inobatsira ndeyokuti kana valve yakavharwa, kurongedza hakusi pasi pekumanikidzwa, hupenyu hwebasa rekutakura hunogona kuwedzerwa, uye basa rekutsiva kurongedza rinogona kuitwa pasi pekumanikidzwa mupombi pamberi pevhavha; iyo yakashata ndeyokuti torque yekufambisa yevhavha yakakura, iyo inenge 1 nguva iyo yekuyerera kwepamusoro, uye simba reaxial revhavha yevhavha yakakura, uye tsvina yevhavha iri nyore kukotama.
Nokudaro, nzira iyi inowanzokodzera mavharuvhu eglobe madiki-diameter (DN50 kana kuti pasi), uye mavharuvhu eglobhu ari pamusoro peDN200 anosarudzirwa nzira yemedia inoyerera ichibva kumusoro. (Mavharuvhu anovhara magetsi anowanzo shandisa svikiro kupinda kubva kumusoro.) Kuipa kwenzira inopinda nezvinobudisa nhau kubva kumusoro kunopesana chaizvo nenzira yainopinda nayo pasi.
- Kuisa chisimbiso
Iyo yekuisa chisimbiso pamusoro pevhavhavha yepasi idiki trapezoidal parutivi rwevhavha core (kunyanya tarisa chimiro chevhavha core), kana iyo yevhavha core inodonha, yakaenzana nekuvhara kwevhavhavha (kana mutsauko wekumanikidza wakakura, hongu, kuvharika hakuna kuomesesa, asi reverse mhedzisiro haina kuipa), iyo gedhi revhavha yeplate yegedhi yakavharwa sechisimbiso chevhavha sechisimbiso chevhavha sevhavha yekuvhara. globe vharafu, uye musimboti wevharuvhu hauzodonha sevharuvhu.
