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 imwe chete ine basa rekucheka mupombi, saka pachava neshamwari dzakawanda dzisingabatanidzi zvakanyanya nevhavha kuti dzivhiringidze maviri. 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 chisimbiso chepamusoro chiri nyore kupfeka, uye kana gedhi revhavha rave pedyo nekuvhara, kusiyana kwekumanikidza pakati. kumberi nekumashure kwepombi yakakura kwazvo, zvichiita kuti chisimbiso chepamusoro chipfeke zvakanyanya.
Chimiro chevhavhavha yegedhi chichave chakanyanya kuoma kupfuura chivharo chepasi, kubva pakuonekwa kwemaonero, munyaya ye caliber imwe chete, gedhi regedhi rakakwirira kudarika valve yeglobe, 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.
Nekuti vharafu yegedhi inogona kuvhurika zvakakwana uye yakavharwa zvizere, kana yanyatsovhurwa, kushorwa kwepakati kuyerera muvharuvhu muviri chiteshi kunenge 0, saka kuvhura uye kuvhara kwevhavha yegedhi kuchave kwakanyanya kuponesa basa. asi ndiro yegedhi iri kure nechekuvharisa, uye nguva yekuvhura nekuvhara irefu.
- Kuiswa uye nzira yekuyerera
Mhedzisiro yevhavha yegedhi inoyerera mumativi ese akafanana, uye hapana chinodiwa chekupinda nekubuda nzira yekuisirwa, uye yepakati inogona kuyerera mumativi ese. Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhafifirika kuisirwa zvinonyatsoenderana negwara rechiratidzo chemuseve wemuviri wevharuvhu, uye pane chinongedzo chakajeka pamusoro pegwara rekupinza uye kutumira kunze kwenyika kwevharuvhu, uye mafambiro evharuvhu "matatu kusvika ” kuChina kunobva 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-kuvhavha mavharuvhu ndeye 3-5 nguva iyo yegedhi mavharuvhu. Paunenge uchivhura nekuvhara, zvakakosha kumanikidza kuvhara kuti uwane chisimbiso, spool yevhavha yevhavhavha yeglobe inongosangana nepamusoro pekuvhara kana yakavharwa zvachose, saka kupfeka kwechisimbiso kuduku zvikuru, nokuti. kuyerera kwesimba guru rinoda kuwedzera actuator Yevhavha yeglobe inofanira kuterera kune torque control mechanism kugadzirisa.
Ivhavha yevhu ine nzira mbiri dzekuisa, imwe ndeyokuti svikiro rinogona 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 pevhavha yeglobe idiki trapezoidal parutivi rwevhavha core (kunyatso tarisa chimiro chevhavha core), kana iyo yevhavha yepakati ichidonha, yakaenzana nevhavha yekuvhara (kana mutsauko wekumanikidza wakakura, hongu, kuvharika hakuna kuomesesa, asi reverse mhedzisiro haina kushata), vharafu yegedhi yakavharwa nedivi revhavha yepakati gedhi ndiro, yekuisa chisimbiso haina kunaka sevhavha yepasi, uye vheji yepakati ichaita. kwete kudonha sevharuvhu yepasi.
