Malinga ndi mawonekedwe osindikiza, ma valve am'magulu nthawi zambiri amagawika m'magulu osiyanasiyana, monga: valavu ya chipata, mphero yofananira, chipata chofananira kawiri, chipata cha chipata chophatikizira, ndi zina zambiri. ofanana mavavu chipata.
1. Mdima wakuda mphero mphero valavu
Gawo lotsegulira ndi kutseka kwa valavu yakuda ya chipata ndi mbale ya pachipata, kayendedwe ka chipata cha chipata chimayang'ana komwe kumayendera madzimadzi, valavu yapa chipata imatha kutseguka kwathunthu komanso kutsekedwa kwathunthu, siyingasinthidwe ndikukwapulidwa . Chipata cha chipata chili ndi nkhope ziwiri zosindikiza. Maonekedwe awiri osindikizira a valve yamagetsi omwe amagwiritsidwa ntchito kwambiri amapangira mphero. Mpweya wa mphero umasiyanasiyana ndi magawo a valavu, nthawi zambiri 50, ndi 2 ° 52 'pomwe kutentha kwapakati sikukwera. Chipata cha mphero vavu chipata opangidwa ndi Zhejiang Star Ou valavu akhoza kukhala lonse, wotchedwa okhwima chipata; Itha kupangidwanso kukhala chipata chomwe chimatha kupanga mapangidwe owongoletsa ukadaulo wake ndikupanga kupatuka kwa Angle yosindikiza pokonza. Chipata ichi chimatchedwa chipata chotanuka.
2. Kutchinjiriza vavu chipata
Matenthedwe otsekemera a chipata amagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, zitsulo, mankhwala ndi machitidwe ena, jekete la valavu limalumikizidwa pakati pazitsulo ziwiri za valavu, mbali ya valavu, pansi pake pamalumikizidwa ndi jekete, jekete imatha kuyenda momasuka kudzera mu nthunzi kapena zina zotentha zotchingira, kuti zitsimikizire kuti sing'anga yoyenda imatha kuyenda bwino kudzera pa valavu.
3. Valavu yapakhomo
Gawo lotsegulira ndi kutsekera kwa valavu yamkati yamatayala ndi thumba lolumikizidwa ndi pulagi, malo osindikizira amakhala osalala kapena ozungulira, ndipo chimbale chimayenda molunjika pamzere wapakatikati wamadzi. Mapangidwe a tsinde la valavu, pali mitundu yokweza ndodo (kukweza tsinde, mawilo osakweza), palinso kukweza mtundu wa ndodo (handwheel ndi tsinde la valavu palimodzi pokweza, mtedza mu thupi la valavu). Mavavu oyenda padziko lonse ali oyenera kutsegulira kwathunthu ndi kutseka kwathunthu. Kusintha ndi kupindika sikuloledwa. Mtundu wa valavu umayenera kukhazikitsidwa mopingasa mu payipi.
4. Chitsulo chosapanga dzimbiri chachitsulo
Zosapanga dzimbiri zitsulo zipata vavu mwadzina kuthamanga: 1.0Mpa, 1.6Mpa, 2.5Mpa; 2, kuthamanga kwa mayeso a chipolopolo: P = 1.5Pn; 3. Sindikiza kuthamanga kwa mayeso: P = 1.1Pn; 4, kubwereketsa kuthamanga: PN1.0MPa zosapanga dzimbiri vavu chipata 0,09 ~ 0.8Mpa, PN1.6Mpa zosapanga dzimbiri vavu chipata 0.10 ~ 1.2Mpa, PN2.5Mpa zosapanga dzimbiri vavu chipata 0.15 ~ 1.6Mpa; 5. Chida chogwiritsa ntchito: madzi; 6. Kutentha kovomerezeka: 0 ℃ ~ 180 ℃.
5. zotanuka mpando valavu chipata vavu
6. Valavu ya chipata cha mpeni
Gawo lotsegulira ndi kutsekera la valavu ya chipata ndi mbale ya pachipata, mayendedwe a chipata cha chipata chimayang'ana kutsogolo kwa madzimadzi, cholembera cha mpeni pachipata chimatha kutseguka kwathunthu komanso kutsekedwa kwathunthu, sichingasinthidwe ndi wopunduka. Chipata cha chipata chili ndi nkhope ziwiri zosindikiza. Maonekedwe awiri osindikizira a valve yamagetsi omwe amagwiritsidwa ntchito kwambiri amapangira mphero. Mphero ya Angulo imasiyanasiyana ndi magawo a valavu, omwe nthawi zambiri amakhala 50. Itha kupangitsanso kuti ipange kutsetsereka kwa nkhosa yamphongo, kuti ikwaniritse kupanga bwino, komwe kumapangidwira malo osindikizira a Angle pokonza njira zopatuka, chipata ndi wotchedwa zotanuka chimbale mtundu mpeni vavu chatsekedwa, kusindikiza pamwamba kungodalira kuthamanga sing'anga kuti asindikize, kuti zimadalira kuthamanga sing'anga, chimbale adzakhala mbali ina ya mpando valavu kusindikiza kuthamanga padziko kuonetsetsa kuti chisindikizo nkhope chisindikizo, Zhejiang nyenyezi ou mtundu mpeni vavu chipata ndi valavu amatenga kusindikiza kukakamizidwa, valavu ndi chatsekedwa, kudalira mphamvu kunja anakakamiza nkhosa kuthamanga pampando, kuonetsetsa kusindikiza pamwamba pa mtundu uwu wa vavu kusindikiza adzakhala ambiri anaika mu payipi.
7. Valavu yotsekera yotentha pang'ono
Gawo lotsegulira ndi kutseka kwa valavu yotsekera yotentha ndi mbale ya pachipata, kayendedwe ka mbale ya chipatacho ndiwofanana ndi komwe madzi amayendera, valavu yapa chipata imatha kutseguka kwathunthu komanso kutsekedwa kwathunthu, osati kuwongolera ndi kupindika. Chipata cha chipata chili ndi nkhope ziwiri zosindikiza. Maonekedwe awiri osindikizira a valve yamagetsi omwe amagwiritsidwa ntchito kwambiri amapangira mphero. Mpweya wa mphero umasiyanasiyana ndi magawo a valavu, nthawi zambiri 50, ndi 2 ° 52 'pomwe kutentha kwapakati sikukwera. Chipata cha valavu ya chipata cha wedge chitha kupangidwa kukhala yathunthu, yotchedwa chipata cholimba; Itha kupangidwanso kukhala chipata chomwe chimatha kupanga mapangidwe owongoletsa ukadaulo wake ndikupanga kupatuka kwa Angle yosindikiza pokonza. Chipata ichi chimatchedwa chipata chotanuka.
8. Flanged Buku vavu chipata
Flanged chipata vavu ndi flange chipata vavu mode akafuna, akafuna kulumikiza ndi wamba. Flanged gate valve ndi yolimba komanso yodalirika ikagwiritsidwa ntchito mu payipi, chifukwa chake sikulakwa kugwiritsa ntchito valavu yampata wa flange mu payipi yothamanga.
9.Valavu yapa gate
10. Open valavu tsinde mphero chipata
Mtundu wa valavu wapachipata, malinga ndi mawonekedwe osindikiza pamwamba atha kugawidwa m'magulu amtundu wa valavu ndi valavu yofananira, chipata cha mtundu wa wedge chitha kugawidwa: mtundu umodzi wa chipata, mtundu wa chipata chachiwiri ndi chipata chosinthasintha; Ma valve ofanana ofanana amatha kugawidwa pachipata chimodzi ndi chipata chachiwiri. Malinga ndi malo oyeserera a tsinde, imatha kugawidwa mu valavu yowala ya tsinde ndi valavu yakuda. Valavu yachitetezo cha tsinde ikatsekedwa, malo osindikizira amatha kusindikizidwa kokha ndi kuthamanga kwapakati, ndiye kuti, malo osindikizira pachipata amakanikizidwa mbali inayo ya mpando wa valavu kuti awonetsetse kusindikiza, komwe kuli kudzisindikiza . Ma valve ambiri am'makomo amakakamizidwa kusindikiza, ndiye kuti, valavu ikatsekedwa, ndikofunikira kudalira mphamvu yakunja kukakamiza chipata cha mpando wa valavu kuti zitsimikizire malo osindikizira.
Osewera chitsulo vavu pachipata ndi ulusi mkati
Gawo lotsegulira ndi kutseka kwa valavu yamkati yolumikizira ulusi ndi chimbale chowoneka ngati pulagi, malo osindikizira ndiwophwatalala kapena ozungulira, ndipo chimbale chimayenda molunjika pamzere wapakatikati wamadzimadzi. Mapangidwe a tsinde la valavu, pali mitundu yokweza ndodo (kukweza tsinde, mawilo osakweza), palinso kukweza mtundu wa ndodo (handwheel ndi tsinde la valavu palimodzi pokweza, mtedza mu thupi la valavu). Mavavu oyenda padziko lonse ali oyenera kutsegulira kwathunthu ndi kutseka kwathunthu. Kusintha ndi kupindika sikuloledwa.
11. Lathyathyathya vavu chipata
Valavu yapakhomo lathyathyathya ndi valavu yotsetsereka yokhala ndi chitseko chofanana chotseka chipata. Wotsekera atha kukhala chipata chimodzi kapena chipata chokhala ndi njira ziwiri zobweretsera pakati pawo. Kupanikizika kwa chipata cha mpando kumawongoleredwa ndi kuthamanga kwapakati kogwiritsa ntchito chipata choyandama kapena mpando woyandama. Pankhani ya valavu yapawiri yapa disc, zida zakumbuyo zomwe zimawonedwa pazipata ziwirizi zimatha kuwonjezera izi.
12. Kawiri chimbale kuponyera chitsulo vavu chipata
Ma valve awiri achitsulo opangira ma iron amagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, mankhwala, magetsi ndi mafakitale ena. Kupanikizika mwadzina ≤ L, 0MPa nthunzi, madzi, mafuta ndi mapaipi ena atolankhani, ogwiritsidwa ntchito potsegula ndi kutseka.
