SDV vharafu (Shut Down Valve)
✧ Tsanangudzo
Vhuru yeSDV (Shut Down Valve) ivharuvhu ine kuvhura kwakaita V kune rimwe divi rehafu-bhora spool. Nekugadzirisa kuvhurwa kwe spool, nzvimbo yepakati-yepakati yepakati inoyerera inoshandurwa kugadzirisa kuyerera. Inogona zvakare kushandiswa kushandura kudzora kuona kuvhurwa kana kuvhara kwepombi. Iine maitiro ekuzvinatsa, inogona kuwana kuyerera kudiki kugadziridzwa mudiki kuvhura renji, inogadziriswa chiyero yakakura, yakakodzera kune fiber, yakanaka particles, slurry media.
Chikamu chekuvhura nekuvhara chevhavha yebhora reV-mhando ibhora rine denderedzwa chiteshi, uye maviri hemispheres akabatanidzwa nebhaudhi uye anotenderera 90 ° kuti awane chinangwa chekuvhura nekuvhara.
Inoshandiswa zvakanyanya mune otomatiki control system ye petroleum, indasitiri yemakemikari uye zvichingodaro.

✧ Zvimiro zveSDV vharafu (Shut Down Valve) (V port)
1. kupikisa kwemvura kuduku, iyo inoyerera coefficient yakakura, chiyero chinogadziriswa chakakwirira. Inogona kusvika: 100: 1, iyo yakakura kudarika chiyero chinogadziriswa cheyakarurama-seat regulating valve, maviri-seat regulating valve uye sleeve regulating valve. Kuyerera kwayo maitiro anenge akaenzana muzana.
2. kuiswa chisimbiso kwakavimbika. Iyo yekuvuza giredhi yesimbi yakaoma chisimbiso chimiro iKirasi IV yeGB/T4213 "Pneumatic Control Valve". Iyo yekuvuza giredhi yeyakapfava chisimbiso chimiro iKirasi V kana Kirasi VI yeGB/T4213. Kune yakaoma chisimbiso chimiro, iyo bhora musimboti yekuisa chisimbiso pamusoro inogona kugadzirwa yakaoma chromium plating, yakatarisana necobalt yakavakirwa simende carbide, kumwaya tungsten carbide kupfeka-inodzivirira coating, nezvimwewo, kuvandudza hupenyu hwesevhisi yevhavha core chisimbiso.
3. vhura uye vhara nekukurumidza. V-mhando yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhu,kubva kuvhurika zvakazara kusvika yakavharwa spool Angle 90°,yakashongedzerwa neAT piston pneumatic actuator inogona kushandiswa kukurumidza kucheka mamiriro. Mushure mekuisa iyo yemagetsi valve positioner, inogona kugadziridzwa zvinoenderana neiyo analogi chiratidzo 4-20Ma reshiyo.
4. kuita zvakanaka kwekuvhara. Iyo spool inotora 1/4 hemispherical chimiro ine unilateral chigaro chimiro. Kana paine zvimedu zvakasimba mukati, iyo mhango yekuvhara haizoitike seyakajairwa O-mhando bhora mavharuvhu. Hapana mukaha pakati pebhora rakafanana neV uye chigaro, iyo ine simba guru rekuveura, rinonyanya kukodzera kutonga kwekumiswa uye zvimedu zvakasimba zvine fiber kana zviduku zvakasimba. Mukuwedzera, kune V-shaped bhora mavharuvhu ane spool yepasi rose, iyo inonyanya kufanirwa nepamusoro-soro mamiriro ezvinhu uye inogona kunyatsoderedza deformation yebhokisi rebhora apo kusiyana kwepamusoro kunoitwa. Iyo inotora chisimbiso chechigaro chimwe chete kana maviri chigaro chisimbiso chimiro. Iyo V-yakaita bhora vharafu ine kaviri chigaro chisimbiso inonyanya kushandiswa kuchena yepakati kuyerera mutemo, uye yepakati ine zvimedu inogona kukonzera njodzi yekuvharika yepakati mhango.
5. V-mhando yevhavha yebhora igadziriro yebhora yakagadziriswa, chigaro chinotakurwa nechitubu, uye chinogona kufamba nenzira yekuyerera. Inogona kudzorera otomatiki kupfeka kwe spool, kurebesa hupenyu hwesevhisi. Chitubu chine hexagonal spring, wave spring, disc spring, cylindrical compression spring zvichingodaro. Kana iyo yepakati iine tsvina shoma, zvakakosha kuwedzera zvindori zvekuvhara kuchitubu kuti zvidzivirire kubva kune tsvina. Kune zvigaro zviviri zvakavharwa pasi rose spool V-bhora mavharuvhu, iyo inoyangarara bhora chimiro inoshandiswa.
6. kana paine moto uye anti-static zvinodiwa, iyo yevhavha yepakati inogadzirwa nesimbi yakaoma chisimbiso chimiro, iyo yekuzadza inogadzirwa neinochinjika graphite uye zvimwe yakakwirira tembiricha inodzivirira, uye hunde yevharuvhu ine chisimbiso fudzi. Tora electrostatic conduction matanho pakati pevharuvhu muviri, dzinde uye sphere. Teerera neGB/T26479 inodzivirira moto chimiro uye GB/T12237 antistatic zvinodiwa.
7. V-shaped ball valve maererano neyakasiyana-siyana yekuisa chisimbiso chebhokisi rebhora, pane zero eccentric structure, single eccentric structure, double eccentric structure, matatu eccentric structure. Chimiro chinowanzo shandiswa ndeye zero eccentric. Iyo eccentric chimiro inogona kukurumidza kusunungura spool kubva pachigaro kana ichivhurwa, kuderedza kupfeka kwechisimbiso mhete uye kuwedzera hupenyu hwebasa. Kana yakavharwa, eccentric simba rinogona kugadzirwa kuti riwedzere kuvharika kwekuita.
8. Nzira yekufambisa yeV-type bhora valve ine mhando yekubata, worm gear transmission, pneumatic, magetsi, hydraulic, electro-hydraulic linkage uye mamwe maitiro ekufambisa.
9.V-mhando yekubatanidza bhora revhavha ine flange yekubatanidza uye clamp yekubatanidza nzira mbiri, yepasi rose spool, kaviri chigaro chisimbiso chimiro uye tambo yekubatanidza uye socket welding, butt welding uye dzimwe nzira dzekubatanidza.
10.ceramic bhora vharafu zvakare ine V-yakaumbwa bhora musimboti chimiro. Yakanaka kupfeka kuramba, asiwo asidhi uye alkali corrosion kuramba, yakanyanya kukodzera kudzora kwegranular media. Fluorine lined ball valve inewo V-shaped ball core structure, iyo inoshandiswa kudzora nekudzora acid uye alkali corrosive media. Iyo yekushandiswa kwemhando yeV-mhando yebhora vharafu inowedzera uye yakawanda.
✧ Mushure-Kutengesa Sevhisi
Basa rekutengesa-shure kweSDV valve (Shut Down Valve) (V port) inokosha zvikuru, nokuti chete panguva yakakodzera uye inoshanda mushure mekutengesa-basa inogona kuvimbisa kushanda kwayo kwenguva refu uye yakagadzikana. Izvi zvinotevera zvekutengesa-sevhisi zvemukati zvemamwe mavharuvhu anoyangarara:
1.Kuisa uye kutumirwa: Mushure mekutengesa vashandi vebasa vanoenda kunzvimbo yekuisa uye kugadzirisa iyo inoyangarara bhora valve kuti ive nechokwadi chekushanda kwayo kwakasimba uye kwakajairika.
2.Maintenance: Nguva dzose chengetedza valve inoyangarara kuti uone kuti iri mumamiriro ekushanda zvakanaka uye kuderedza kukundikana.
3.Troubleshooting: Kana iyo valve inoyangarara yakatadza, vashandi vebasa mushure mekutengesa vachaita pa-saiti kugadzirisa dambudziko munguva pfupi inogoneka kuti ive nechokwadi chekushanda kwayo.
4.Chigadzirwa chekuvandudza nekusimudzira: Mukupindura kune zvitsva uye matekinoroji matsva ari kubuda mumusika, mushure mekutengesa-kutengesa vashandi vachakurumidza kukurudzira kugadzirisa uye kusimudzira mhinduro kune vatengi kuti vavape zviri nani zvigadzirwa zvevharuvhu.
5. Ruzivo rwekudzidzisa: Mushure mekutengesa vashandi vebasa vanozopa ruzivo rwevharuvhu kune vashandisi kuvandudza manejimendi uye nhanho yekuchengetedza yevashandisi vachishandisa mavharuvhu ebhora anoyangarara. Muchidimbu, mushure mekutengesa sevhisi yevhavha inoyangarara yebhora inofanirwa kuvimbiswa munzira dzese. Nenzira iyi chete inogona kuunza vashandisi ruzivo rwakanaka uye kuchengetedza kutenga.
