Vharuvhu yeSDV (Vharuvhu Yekudzima)
✧ Tsananguro
Vharuvhu yeSDV (Shut Down Valve) ivharuvhu ine musuwo wakaita seV kune rumwe rutivi rwehalf-ball spool. Nekugadzirisa musuwo wespool, nzvimbo inoyambuka yepakati inoshanduka kugadzirisa kuyerera. Inogona zvakare kushandiswa kudzora switch kuti ione kuvhurwa kana kuvharwa kwepombi. Inozvichenesa pachayo, inogona kugadzirisa kuyerera kudiki munzvimbo diki yekuvhura, chiyero chinogadziriswa chakakura, chakakodzera fiber, zvidimbu zvidiki, slurry media.
Chikamu chekuvhura nekuvhara chevharuvhu yebhora yerudzi rweV ibhora rine denderedzwa, uye ma hemispheres maviri akabatana nebhaudhi uye anotenderera 90° kuti azadzise chinangwa chekuvhura nekuvhara.
Inoshandiswa zvakanyanya muhurongwa hwekudzora otomatiki hwemafuta, indasitiri yemakemikari nezvimwewo.

✧ Zvinhu zviri muvharuvhu yeSDV (V port) (Shut Down Valve)
1. Kuramba kwemvura kudiki, chiyero chekuyerera kwemvura chakakura, chiyero chinogadziriswa chakakwira. Chinogona kusvika :100:1, icho chakakura kupfuura chiyero chinogadziriswa chevharuvhu rinotonga rine chigaro chimwe chete, vharuvhu rinotonga rine chigaro chimwe chete uye vharuvhu rinotonga rine sleeve. Hunhu hwaro hwekuyerera kwemvura hunenge hwakaenzana.
2. Kuvhara kwakavimbika. Kubuda kwechikamu chesimbi chakasimba chesimbi iClass IV yeGB/T4213 "Pneumatic Control Valve". Chikamu chekubuda kwechikamu chesoft seal iClass V kana Class VI yeGB/T4213. Kune hard sealing structure, ball core sealing surface inogona kugadzirwa ne hard chromium plating, surfacing cobalt based cemented carbide, spraying tungsten carbide wear-resistant coating, nezvimwewo, kuti kuvandudza hupenyu hwebasa re valvu core seal.
3. Vhura wovhara nekukurumidza. Vharuvhu yebhora yemhando yeV ivharuvhu yekurova ine kona, kubva pakuvhurwa zvizere kusvika pakuvharwa zvizere. Angle 90°, ine AT piston pneumatic actuator inogona kushandiswa pakucheka nekukurumidza. Mushure mekuisa positioner yevharuvhu yemagetsi, inogona kugadziriswa zvichienderana nechiyero cheanalog signal 4-20Ma.
4. Kushanda zvakanaka pakuvharira. Spool inoshandisa 1/4 chimiro chehemispherical chine chimiro chechigaro cheupande mumwe. Kana paine zvidimbu zvakasimba mukati mepakati, kuvharika kwegomba hakuzoitiki semavharuvhu ebhora emhando yeO. Hapana mukaha pakati pebhora rakaita seV nechigaro, chine simba guru rekuchekerera, rakakodzera kudzora suspension uye zvidimbu zvakasimba zvine fiber kana zvidimbu zvidiki zvakasimba. Pamusoro pezvo, kune mavharuvhu ebhora akaumbwa seV ane global spool, ayo akakodzera mamiriro ekumanikidzwa kwakanyanya uye anogona kuderedza zvinobudirira deformation yepakati pebhora kana musiyano wekumanikidzwa kwakanyanya waitwa. Inoshandisa sealing yechigaro chimwe chete kana chimiro chekuvharira chigaro kaviri. Vharuvhu yebhora yakaumbwa seV ine seal yechigaro kaviri inonyanya kushandiswa kudzora kuyerera kwepakati kwakachena, uye medium ine zvidimbu inogona kukonzera njodzi yekuvhara cavity yepakati.
5. Vharuvhu yebhora yerudzi rweV chimiro chebhora chakagadzika, chigaro chakazadzwa nechitubu, uye chinogona kufamba munzira yekuyerera. Inogona kudzoreredza otomatiki kupera kwespool, kuwedzera hupenyu hwebasa. Chitubu chine chitubu chine hexagonal, chitubu chemafungu, chitubu chedhisiki, chitubu chekumanikidza checylindrical nezvimwewo. Kana medium iine tsvina diki, zvinodikanwa kuwedzera mhete dzekuvhara muchitubu kuti chidzivirire kubva pakusvibiswa. Kune mavharuvhu eV-ball epasi rese akavharirwa kaviri, chimiro chebhora rinoyangarara chinoshandiswa.
6. Kana paine zvinodiwa zvemoto uye zvinopesana nestatic, vharuvhu inogadzirwa nesimbi yakasimba seal structure, filler inogadzirwa ne flexible graphite nezvimwe zvinhu zvinodzivirira kupisa kwakanyanya, uye vharuvhu ine sealant shoulder. Tora matanho e electrostatic conduction pakati pe valvu, stem ne sphere. Tevedzera GB/T26479 fire-resistant structure uye GB/T12237 antistatic requirements.
7. Vharuvhu yebhora yakaita seV zvichienderana nechimiro chakasiyana chekuvharira chepakati pebhora, hapana chimiro chisina kujeka, chimiro chimwe chete chisina kujeka, chimiro chakapetwa kaviri chisina kujeka, chimiro chetatu chisina kujeka. Chimiro chinowanzoshandiswa hachina kujeka. Chimiro chisina kujeka chinogona kukurumidza kusunungura spool kubva pachigaro kana chavhurwa, kuderedza kupera kwemhete yechisimbiso uye kuwedzera hupenyu hwebasa. Kana yakavharwa, simba risina kujeka rinogona kugadzirwa kuti riwedzere kushanda kwechisimbiso.
8. Nzira yekutyaira yeV-type ball valve ine mhando yemubato, worm gear transmission, pneumatic, electric, hydraulic, electro-hydraulic linkage nedzimwe nzira dzekutyaira.
Kubatana kwevharuvhu yebhora yemhando yeV-9. Kune nzira mbiri dzekubatanidza flange neclamp, yekubatanidza global spool, double sealing structure uye thread connection uye socket welding, butt welding nedzimwe nzira dzekubatanidza.
10. Vharuvhu yebhora yeceramic ine chimiro chepakati pebhora chakaita seV. Inodzivirira kupera zvakanaka, asiwo inodzivirira ngura neacid nealkali, yakakodzera kudzora granular media. Vharuvhu yebhora ine fluorine ine chimiro chepakati pebhora chakaita seV, chinoshandiswa kudzora nekutonga ngura neacid nealkali media. Mhando dzekushandisa vharuvhu yebhora yemhando yeV dzakakura.
✧ Basa reKutengesa Mushure meKutengeswa
Basa rekuvhara vharuvhu reSDV (Shut Down Valve) (V port) mushure mekutengesa rakakosha zvikuru, nekuti basa rekuvhara vharuvhu reSDV (Shut Down Valve) (V port) rinoitwa panguva chaiyo uye rinoshanda chete ndiro rinogona kuita kuti rishande kwenguva refu uye zvakagadzikana. Izvi zvinotevera ndizvo zviri mubasa rekuvhara vharuvhu remabhora rinoyangarara mushure mekutengesa:
1. Kuisa uye kutumirwa: Vashandi vebasa rekutengesa mushure mekutengesa vachaenda kunzvimbo yacho kunoisa nekugadzirisa vharuvhu yebhora inoyangarara kuti ive nechokwadi chekuti inoshanda zvakanaka uye yakajairika.
2.Kugadzirisa: Gara uchichengetedza vharuvhu yebhora inoyangarara kuti uve nechokwadi chekuti iri mumamiriro akanaka ekushanda uye kuderedza mwero wekukundikana.
3. Kugadzirisa Matambudziko: Kana vharuvhu yebhora inoyangarara ikakundikana, vashandi vebasa rekutengesa mushure mekutengesa vachaita kugadzirisa matambudziko panzvimbo iyoyo munguva pfupi iri kutevera kuti vave nechokwadi chekuti inoshanda zvakajairika.
4. Kugadzirisa nekusimudzira chigadzirwa: Mukupindura kune zvinhu zvitsva uye matekinoroji matsva ari kubuda mumusika, vashandi vebasa rekutengesa mushure mekutengesa vachakurumidza kukurudzira mhinduro dzekuvandudza nekuvandudza kune vatengi kuti vavape zvigadzirwa zvevharuvhu zviri nani.
5. Kudzidziswa kweruzivo: Vashandi vebasa rekutengesa mushure mekutengesa vachadzidzisa vashandisi ruzivo rwemavharuvhu kuti vavandudze nhanho yekutarisira nekuchengetedza vashandisi vachishandisa mavharuvhu ebhora rinoyangarara. Muchidimbu, basa rekuvhara vharuvhu rebhora rinoyangarara mushure mekutengesa rinofanira kuvimbiswa kumativi ese. Nenzira iyi chete ndipo panogona kuunza vashandisi ruzivo rwuri nani uye kuchengetedzeka pakutenga.
