Chidziwitso choyambirira cha ma valve ndi magulu (a)valavu zambiri! Nazi zonse zomwe simukudziwa za ma Angle valves
Vavu ndi mafuta, mankhwala Ding :, malo opangira magetsi, payipi yotulukira kwautali, kupanga mapepala, mafakitale a nyukiliya, mitundu yonse ya uinjiniya wa cryogenic, mlengalenga ndi mafuta akunyanja ndi mbali zina zoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, throttling, kuteteza countercurrent, kupatutsa kapena kuthamanga kuthamanga ntchito ntchito. Mavavu owongolera madzimadzi amasiyanasiyana kuchokera pazida zosavuta zodulira mpaka makina ovuta kwambiri owongolera. Valavu iyenera kudalira kuviika kapena kusuntha koyera kuti apange magawo ake otsegula ndi otseka kuti anyamule, kusuntha, kuyendayenda kapena kuyendayenda, kuti asinthe kukula kwa malo ake oyenda, kuti akwaniritse ntchito yolamulira.
Valavu ndi mafuta, Ding Ding: , kuletsa ntchito zotsutsana, shard kapena flow pressure relief.
Mavavu owongolera madzimadzi amasiyanasiyana kuchokera pazida zosavuta zodulira mpaka makina ovuta kwambiri owongolera. Kukula kodziwikiratu kwa mavavu kumachokera ku mavavu ang'onoang'ono a zida kupita ku mavavu a mapaipi a mafakitale okhala ndi kukula kwake mpaka 10 m ndikulemera matani angapo. Mavavu angagwiritsidwe ntchito kulamulira mpweya, madzi, nthunzi, mitundu yonse ya zikuwononga mankhwala TV matope, mafuta, zitsulo madzi ndi radioactive madzimadzi ndi mitundu ina ya madzimadzi otaya. Vavu ntchito kuthamanga kungakhale kuchokera 1.3 × 10-3MPa kuti 1000MPa. Kutentha kwa ntchito kuchokera -269 ℃ mpaka 1430 ℃ kutentha kwambiri. Kuwongolera mavavu kumatha kutengera njira zosiyanasiyana zopatsirana, monga pamanja, magetsi, pneumatic, hydraulic, magetsi kapena hydraulic hydraulic linkage ndi electromagnetic drive; Angathenso kukhala pansi pa zochita za kuthamanga, kutentha kapena mitundu ina ya uta wozindikira, malinga ndi zomwe zinakonzedweratu kuti achitepo, kapena kungotsegula kapena kutseka. Valavu iyenera kudalira kuviika kapena kusuntha koyera kuti apange magawo ake otsegula ndi otseka kuti anyamule, kusuntha, kuyendayenda kapena kuyendayenda, kuti asinthe kukula kwa malo ake oyenda, kuti akwaniritse ntchito yolamulira.
1. Gulu la valavu Mavavu osiyanasiyana, ndi kuwongolera kosalekeza kwa mitundu yonse ya zida zonse zoyenda ndi magwiridwe antchito, mitundu ya ma valve ikukulirakulirabe, ndipo pali njira zingapo zogawa.
1, molingana ndi gulu lodziwikiratu komanso loyendetsa
(1) Ma valve odziwikiratu amadalira mphamvu ya sing'anga (madzi, mpweya, nthunzi, etc.) kuti igwire ntchito yokha, monga ma valve otetezera, ma valve, ma valve ochepetsera mphamvu, misampha ya nthunzi, misampha ya mpweya, kudula mwadzidzidzi. ma valve, etc.
(2) Vavu yoyendetsa galimoto yoyendetsedwa ndi manja, magetsi, hydraulic kapena pneumatic. Monga valavu pachipata, valavu globe, valavu throttle, valavu butterfly, valavu mpira, valavu pulagi, etc.
2. Gulu pogwiritsa ntchito ndi ntchito
(1) valavu ya truncation imagwiritsidwa ntchito kwambiri kuchepetsa kapena kulumikiza kuyenda kwapakati papaipi. Monga valavu yapadziko lonse lapansi, valavu yachipata, valavu ya mpira, valavu ya pulagi, valavu ya butterfly, valavu ya diaphragm, ndi zina zotero.
(2) Ma valve owunikira amagwiritsidwa ntchito kuti ateteze media backflow. Monga mitundu yosiyana siyana ya valavu cheke.
(3) Ma valve owongolera amagwiritsidwa ntchito makamaka kusintha kuthamanga ndi kuyenda kwa sing'anga yamapaipi. Monga valavu yowongolera, valavu yopumira, valavu yochepetsera ndi zina zotero.
(4) Valavu ya shunt imagwiritsidwa ntchito kusintha njira yoyendetsera sing'anga mu payipi, ndipo imagwira ntchito yogawa, shunt kapena kusakaniza sing'anga. Monga mitundu yosiyanasiyana ya valavu yogawa, tee kapena tambala wanjira zinayi, tee kapena valavu ya mpira wanjira zinayi, mitundu yosiyanasiyana ya misampha.
(5) valavu yachitetezo imagwiritsidwa ntchito poteteza chitetezo chambiri, kutulutsa zofalitsa zochulukirapo, kuteteza kupanikizika kuti zisapitirire mtengo womwe watchulidwa. Monga mitundu yosiyanasiyana ya ma valve otetezera.
(6) Ma valve ogwiritsira ntchito ma multi-purpose amagwiritsidwa ntchito m'malo mwa mitundu iwiri, iwiri kapena yambiri ya ma valve, monga ma valve oima, ma valve a mpira, amasiya ma valve otetezera, ndi zina zotero.
(7) Ma valve ena apadera monga valavu ya blowdown, valve blowoff, valve yoyeretsa coke, valavu yodula mwadzidzidzi, ndi zina zotero.
3, malinga ndi gawo lalikulu laukadaulo
1. Gulu ndi kukula mwadzina
(1) valavu yaing'ono yaing'ono kukula kwake DN≤40mm, valavu.
(2) sing'anga m'mimba mwake valavu mwadzina kukula DN50 ~ 300mm valavu.
(3) valavu lalikulu m'mimba mwake mwadzina kukula DN350 ~ 1200mm valavu.
(4) Vavu yaikulu m'mimba mwake mwadzina kukula DN≥1400mm valavu.
3.2 Ma vacuum valves osankhidwa ndi kukakamiza mwadzina - ma valve okhala ndi mphamvu yogwira ntchito yotsika kuposa kuthamanga kwa mumlengalenga.
[2] Valavu yotsika - kuthamanga mwadzina PN≤1.6MPa valavu:
(3) Vavu yapakati - kuthamanga mwadzina PN2,.5 ~ 6.4 mpa vavu:
(4) Valavu yapamwamba - kuthamanga kwadzina PN10. 0-80 pa. 0MPa valve.
(5) valavu yapamwamba kwambiri - kuthamanga mwadzina PN≥100MPa valavu.
3.3 Amasankhidwa ndi kutentha kwapakati
(]) Vavu yotentha kwambiri ya T450 ℃.
(2) sing'anga kutentha valavu 120≤t≤450℃ vavu.
{3) Valavu yotentha yachibadwa - 29 ℃ ≤t≤120 ℃ vavu.
(4) Low kutentha valavu 100 ℃ ≤t≤ 29 ℃ vavu.
(5) ** valavu kutentha t 100 ℃ valavu.
3. 4 Kugawikana ndi thupi
(1) Mavavu osakhala achitsulo monga mavavu a ceramic, mavavu azitsulo zamagalasi, mavavu apulasitiki
(2) Mavavu achitsulo - monga valavu yamkuwa, valavu yotsogolera, titaniyamu alloy valve, chibwano chachitsulo, valavu ya Monel, valavu ya Hastelloy, valavu yachitsulo, valavu yachitsulo, valavu yachitsulo yachitsulo, valavu yachitsulo yachitsulo, valavu yapamwamba yachitsulo.
(3) Mavavu okhala ndi zitsulo - monga ma valve otsogolera, ma valve opangidwa ndi pulasitiki, ma valve okhala ndi enamel.
Tsatanetsatane wa valve! Nazi zonse zomwe simukudziwa za ma Angle valves
Ngati valavu ya Angle ikutha, ndipo imapezeka kuti pakati pa valavu ya Angle yathyoka, imatha kusintha valavu ya Angle. Zikapezeka kuti valavu yotayikira ya Angle valve ili pamalopo, ingokulunganinso lamba wamafuta osindikizira ndikumangitsa. M'moyo weniweni, valavu ya makona atatu pa chowotcha chamadzi inaphulika mwamsanga pamene nyumba yatsopano ya eni ena inatha, zomwe zinachititsa kuti mipope iwonongeke ndikusefukira pansi, kabati ya TV, zovala, etc. Izi zimachitika, kawirikawiri chifukwa cha khalidwe la valavu ya Angle sichimayambitsidwa ndi. Choncho, pokonza nyumba, tiyenera kulabadira kusankha wabwino Angle valavu musakhale khobiri anzeru ndi mapaundi opusa.
