Indlela yokwelapha yokuvuza kwevalvu yokuvala indawo Ingabe i-valve idinga ukufaka imigomo ye-bypass valve kanye nezilungiselelo?

Khipha amabhawodi ngokulinganayo futhi ngokulinganayo. Uma kunesidingo, sebenzisa i-torque wrench. Ukulayisha kuqala kufanele kuhlangabezane nezidingo futhi kungabi kukhulu kakhulu noma kuncane. Kufanele kube khona imvume ethile yokulayisha kuqala ekuhlanganyeleni kwe-flange nentambo. Umhlangano we-gasket kufanele uhambisane nendawo futhi amandla kufanele afane. I-gasket lap kanye ne-double gasket ayivunyelwe.
Imbangela:
I-1, ukugaya ukugaya kungalingani, ayikwazi ukwakha umugqa oseduze.
2. Ukuxhumana phakathi kwesiqu nengxenye yokuvala kumisiwe, akuqondile noma kugugile.
I-3, ukugoba kwesiqu se-valve noma ukuhlangana akulungile, ukuze ingxenye yokuvala ihlanekezelwe noma ingabi phakathi.
4. Ukukhetha okungalungile kwekhwalithi yezinto ezibonakalayo zokuvala noma ukungakhethi kwe-valve ngokuvumelana nezimo zokusebenza.
Izindlela zokuvimbela nokuqeda:
1. Khetha kahle impahla kanye nohlobo lwe-gasket eshayayo ngokuya ngezimo zokusebenza.
2, ukulungiswa ngokucophelela, ukusebenza kahle.
3, kufanele kube ngokulinganayo futhi symmetrically isikulufa ibhawudo, uma kunesidingo, kufanele asebenzise isikrufu torque, ukulayisha kuqala kufanele ukuhlangabezana nezidingo, hhayi enkulu kakhulu noma encane. Kufanele kube khona imvume ethile yokulayisha kuqala ekuhlanganyeleni kwe-flange nentambo.
4, umhlangano we-gasket kufanele uhambisane, amandla afanayo, i-gasket lap kanye nokusetshenziswa kwe-gasket kabili akuvunyelwe.
5, ukugqwala kokubekwa uphawu okumile, ukucutshungulwa komonakalo, ikhwalithi yokucubungula ayiphezulu, kufanele ilungiswe, ukugaya, ukuhlolwa kombala, ukwenza indawo yokubeka uphawu emile ihlangabezane nezidingo ezifanele.
6. Uma ufaka i-gasket, ukunakwa kufanele kukhokhwe ekuhlanzeni, ukubeka uphawu kufanele kube i-parafini ecacile, futhi i-gasket akufanele iwele phansi.
Ingabe i-valve idinga ukufaka izimiso nezilungiselelo ze-bypass valve? Ngezinye izikhathi sibona ama-valve amakhulu kakhulu kwamanye amapayipi, futhi ahlala efakwe ama-bypass valve. Kungani lokhu? Uyini umsebenzi wayo oyinhloko? Idinga ukufakwa ngaphansi kwaziphi izimo? Buyini ububanzi bevalve yokudlula yemishini ehambisanayo? Eqinisweni, i-valve ye-bypass isethwe epayipini, futhi indima yayo ingahlukaniswa ngamaphoyinti amabili ngokujwayelekile: enye idlala indima yokuzivikela (ingcindezi yokulinganisela kuzo zombili iziphetho), enye i-standby ephuthumayo!

Eqinisweni, i-valve ye-bypass isethwe epayipini, futhi indima yayo ingahlukaniswa ngamaphoyinti amabili ngokujwayelekile: enye idlala indima yokuzivikela (ingcindezi yokulinganisela kuzo zombili iziphetho), enye i-standby ephuthumayo!
Okokuqala, umphumela ovikelayo, kungashiwo ukuthi uyisilinganiso sokuzivikela se-valve eyinhloko, ukuvimbela i-valve ngaphambi nangemva kokuhlukana kwengcindezi kukhulu kakhulu, futhi kubangele ukumelana okuvulekile, i-valve ayilungile ukuvula, ikakhulukazi kwezinye. umthamo omkhulu noma ipayipi lomfutho ophezulu. Ngaphambi kokuvula ipayipi lomfutho ophezulu ngokusebenzisa i-bypass pressure pressure, ukuze ugweme ukucindezela okukhulu okungazelelwe, ukwakheka komthelela epayipini elingaphansi kwevalvu. Noma umehluko wengcindezi phakathi kweziphetho ezimbili ze-valve mkhulu kakhulu, i-torque yokuvula inkulu kakhulu, ukuze ugweme ukulimala kwe-torque ku-valve, i-bypass pressure relief ngaphambi kokuvula i-valve.
Okwesibili, indima yezimo eziphuthumayo, njengepayipi lokulinda elizosetshenziswa, inzuzo enkulu kunazo zonke ukuthi lapho ukwehluleka kwe-valve enkulu, noma isidingo sokugcinwa nokulungiswa kabusha, ungavula ukujikeleza kwe-valve ye-bypass, futhi akuphazamisi ukukhiqizwa okuvamile.
Ukuthi i-valve idinga ukufakwa ngezidingo eziqondene ne-bypass valve kanye nezilungiselelo* okwereferensi)
Ibanga le-2.5mpa, i-DN400 noma ngaphezulu; Ibanga le-4.0mpa, i-DN250 noma ngaphezulu; Ibanga le-6.4mpa, i-DN200 noma ngaphezulu; Ibanga le-10MPa, i-DN150 noma ngaphezulu;
I-valve ye-DN100~DN200, ipayipi lokudlula kanye ne-bypass valve ye-DN20; I-valve ye-DN250~DN600, ipayipi lokudlula kanye nevalve yokudlula ye-DN25; Kumavalvu angaphezu kwe-DN600, ipayipi lokudlula kanye ne-bypass valve yi-DN40.
