✧ Ibisobanuro

Valve ya SDV (Valve yo kuzimya) ni valve ifite umwobo umeze nk'uwa V ku ruhande rumwe rw'igice cy'umubumbe. Mu guhindura umwobo w'umubumbe, agace k'umugezi gakoreshwa hagati gahinduka kugira ngo hakosorwe uruziga. Ishobora kandi gukoreshwa mu kugenzura switch kugira ngo ifungure cyangwa ifunge umuyoboro. Ifite ingaruka zo kwisukura, ishobora kugera ku bushobozi bwo guhindura uruziga mu buryo buto, igipimo gihinduka ni kinini, kibereye fibre, uduce duto, slurry media.
Igice cyo gufungura no gufunga cya valve y'umupira yo mu bwoko bwa V ni uruziga rufite umuyoboro wire, kandi ibice byombi bihujwe na bolt kandi bizunguruka kuri 90° kugira ngo bigere ku ntego yo gufungura no gufunga.
Ikoreshwa cyane mu buryo bwikora bwo kugenzura peteroli, inganda zikora ibinyabutabire n'ibindi.

✧ Ibiranga valve ya SDV (Valve yo kuzimya) (V port)

1. Ubudahangarwa bw'amazi ni buke, igipimo cy'amazi ni kinini, igipimo gishobora guhindurwa ni kinini. Gishobora kugera kuri :100:1, kikaba kinini cyane kurusha igipimo gishobora guhindurwa cya valve igenga intebe imwe, valve igenga intebe ebyiri na valve igenzura amaboko. Imiterere yayo ingana ku kigero kimwe.

2. Gufunga neza. Ingano y'amazi y'icyuma gifunga cyane ni Icyiciro cya IV cya GB/T4213 "Valve yo kugenzura imikorere y'umwuka". Ingano y'amazi y'icyuma gifunga neza ni Icyiciro cya V cyangwa Icyiciro cya VI cya GB/T4213. Ku bijyanye n'imiterere ikomeye yo gufunga, ubuso bwo gufunga bw'inkingi y'umupira bushobora gukorwa mu buryo bukozwe muri chromium ikomeye, carbide ishingiye kuri cobalt, irangi ririnda kwangirika kwa carbide ya tungsten, nibindi, kugira ngo hongerwe igihe cy'imikorere y'inkingi y'icyuma gifunga.

3. fungura kandi ufunge vuba. Valve y'umupira yo mu bwoko bwa V ni valve ifite imiterere y'ingufu, kuva ku ifunguye neza kugeza ku ifunze neza. Inguni ya 90°, ifite AT piston pneumatic actuator ishobora gukoreshwa mu guca vuba. Nyuma yo gushyiraho positioner y'amashanyarazi, ishobora guhindurwa hakurikijwe ikigereranyo cya analog cy'ikimenyetso cya 4-20Ma.

4. Imikorere myiza yo kuziba. Agace gafata 1/4 cy'imiterere y'agace gafite imiterere y'intebe ku ruhande rumwe. Iyo hari uduce dukomeye mu gice cyo hagati, kuziba k'agace kazapfa nk'udupira dusanzwe tw'ubwoko bwa O. Nta cyuho kiri hagati y'umupira ufite ishusho ya V n'intebe, ifite imbaraga nyinshi zo gukata, cyane cyane zikwiriye kugenzura uduce duto duto dufite fibre cyangwa uduce duto dukomeye. Byongeye kandi, hari udupira dufite ishusho ya V dufite spool y'isi yose, dukwiriye cyane mu bihe by'umuvuduko mwinshi kandi dushobora kugabanya neza impinduka mu gice cyo hagati cy'umupira iyo habayeho itandukaniro ry'umuvuduko mwinshi. Gafata imiterere yo gufunga intebe imwe cyangwa imiterere yo gufunga intebe ebyiri. Valve y'umupira ifite ishusho ya V ifite intebe ebyiri ikoreshwa cyane mu kugenzura umuvuduko uciriritse, kandi icyuma gifite uduce gishobora gutera ibyago byo kuziba umwobo wo hagati.

5. Valve y'umupira yo mu bwoko bwa V ni imiterere y'umupira idahinduka, intebe yuzuyemo impera, kandi ishobora kugenda mu nzira y'amazi. Ishobora kwishyura ubusaza bwa spool mu buryo bwikora, ikongera igihe cyo kuyikoresha. Impera ifite impera ya hexagonal, impera y'amazi, impera ya disiki, impera yo gukandagiraho icyuma n'ibindi. Iyo icyuma gifite umwanda muto, ni ngombwa kongeramo impeta zo gufunga kuri spool kugira ngo ikingire umwanda. Ku mpande ebyiri z'umupira w'amaguru wa V zifunga, imiterere y'umupira ugenda hejuru irakoreshwa.

6. Iyo hari ibisabwa mu gutwika no kurwanya static, igice cy'imbere cya valve gikozwe mu cyuma gikomeye cyo gufunga, icyuzuzo gikozwe muri grafiti yoroshye n'ibindi bikoresho birwanya ubushyuhe bwinshi, kandi igice cy'imbere cya valve gifite urutugu rwo gufunga. Fata ingamba zo gukwirakwiza electrostatic hagati y'umubiri wa valve, string n'umubumbe. Huza imiterere ya GB/T26479 idashya n'ibisabwa mu kurwanya static bya GB/T12237.

7. Valve y'umupira ifite ishusho ya V hakurikijwe imiterere itandukanye yo gufunga igice cy'imbere cy'umupira, hari imiterere idasobanutse neza, imiterere imwe idasobanutse neza, imiterere ibiri idasobanutse neza, imiterere itatu idasobanutse neza. Imiterere ikunze gukoreshwa ni ntasobanutse neza. Imiterere idasobanutse ishobora kurekura vuba agahu kava mu ntebe iyo gafunguwe, kugabanya kwangirika kw'impeta yo gufunga no kongera igihe cyo kuyikoresha. Iyo ifunze, imbaraga zidasobanutse zishobora gukorwa kugira ngo zongere ingaruka zo gufunga.

8. Uburyo bwo gutwara umupira wa V-type ball valve bufite ubwoko bw'umukono, uburyo bwo kohereza ibikoresho byo mu bwoko bwa worm, uburyo bwo guhumeka, amashanyarazi, hydraulic, electro-hydraulic linkage n'ubundi buryo bwo gutwara.

Uburyo bwo guhuza umupira bwa 9. V-type V bugira uburyo bwo guhuza flange na clamp mu buryo bubiri, uburyo bwo guhuza spool y’isi yose, imiterere yo gufunga intebe ebyiri n’uburyo bwo guhuza insinga no guhuza socket, guhuza amabuno n’ubundi buryo bwo guhuza.

10. Valve y'umupira wa keramike ifite imiterere y'imbere y'umupira ifite ishusho ya V. Irwanya kwangirika neza, ariko kandi irwanya aside na alkali, ikwiriye cyane mu kugenzura ibyuma binini. Valve y'umupira ifite fluorine ifite imiterere y'imbere y'umupira ifite ishusho ya V, ikoreshwa mu kugenzura no kugenzura ibyuma birwanya aside na alkali. Uburyo valve y'umupira ikoreshwamo ni bwinshi cyane.

✧ Serivisi yo kugurisha nyuma yo kugurisha

Serivisi yo gutanga valvu ya SDV (Shut Down Valve) (V port) nyuma yo kugurisha ni ingenzi cyane, kuko serivisi yo gutanga valvu ya SDV ikorwa ku gihe kandi neza gusa niyo ishobora gutuma ikora neza kandi irambye. Ibi bikurikira ni ibyavuye muri serivisi yo gutanga valvu imwe n'imwe igenda mu kirere:
1. Gushyiraho no gukoresha: Abakozi bashinzwe nyuma yo kugurisha bazajya aho bakoreraga kugira ngo bashyireho kandi bakore neza valve y'umupira igenda igana hejuru kugira ngo ikore neza kandi ihamye.
2. Kubungabunga: Gufata neza buri gihe valve y'umupira igenda irembera kugira ngo urebe ko ikora neza kandi ugabanye igipimo cyo gutsindwa.
3. Gukemura ibibazo: Iyo valve y'umupira igenda igwa, abakozi bashinzwe nyuma yo kugurisha bazakora igikorwa cyo gukemura ibibazo aho biri mu gihe gito gishoboka kugira ngo ikore neza.
4. Kuvugurura no kuvugurura ibicuruzwa: Mu rwego rwo gusubiza ibikoresho bishya n'ikoranabuhanga rishya riri kugaragara ku isoko, abakozi ba serivisi nyuma yo kugurisha bazahita basaba abakiriya ibisubizo byo kuvugurura no kuvugurura kugira ngo babahe ibikoresho byiza bya valve.
5. Amahugurwa ku bumenyi: Abakozi ba serivisi nyuma yo kugurisha bazatanga amahugurwa ku bumenyi bw'amavali ku bakoresha kugira ngo banoze urwego rw'imicungire n'imicungire y'abakoresha bakoresheje amavali y'umupira aremba. Muri make, serivisi nyuma yo kugurisha ya vali y'umupira iremba igomba kwemezwa mu mpande zose. Ni muri ubwo buryo gusa bushobora gutuma abakoresha bagira uburambe bwiza kandi bakagira umutekano mu kugura.
