Valve sealing surface leakage treatment nzira Iyo vharafu inoda kuisa bypass valve nheyo uye Settings?

Cheka mabhaudhi zvakaenzana uye symmetrically. Kana zvichidikanwa, shandisa torque wrench. Iyo preload inofanirwa kusangana nezvinodiwa uye kwete kuve yakakura kana diki. Panofanira kunge paine imwe preload clearance pamubatanidzwa weflange neshinda. Gasket gasket inofanira kuenzaniswa nechepakati uye simba rinofanira kuva yunifomu. Iyo gasket lap uye kaviri gasket hazvibvumidzwe.
Chikonzero:
1, yekuisa chisimbiso pamusoro pekukuya isina kuenzana, haigone kuumba mutsara wepedyo.
2. Kubatana pakati pehunde nechikamu chekuvhara kunomiswa, kwete kutwasuka kana kupfeka.
3, iyo yevhavha stem yekukotama kana kusangana haina kunaka, kuitira kuti chikamu chekuvhara chitsvedzerwe kana kwete pakati.
4. Kusarudzwa kusina kukodzera kwekuvhara pamusoro pehutano hwehutano kana kusasarudzwa kwevhavha maererano nemamiriro ekushanda.
Nzira dzekudzivirira uye kubvisa:
1. Sarudza zvakarurama zvinhu uye rudzi rwe bouncing gasket maererano nemamiriro ekushanda.
2, kunyatsogadzirisa, kushanda zvakanaka.
3, inofanira kuva yakaenzana uye symmetrically screw bhaudhi, kana zvichidikanwa, inofanira kushandisa torque wrench, preload inofanira kusangana nezvinodiwa, kwete yakakura kana diki. Panofanira kunge paine imwe preload clearance pamubatanidzwa weflange neshinda.
4, gungano regasket rinofanira kuenzaniswa, simba rakafanana, gasket lap uye kushandiswa kwekaviri gasket hakubvumirwi.
5, static sealing surface corrosion, kukuvara kwekugadzirisa, kugadzirisa mhando haina kukwirira, kunofanirwa kugadziriswa, kukuya, kuongorora kwemavara, kuita kuti nzvimbo yekuisa chisimbiso isangane nezvinodiwa.
6. Paunenge uchiisa gasket, kutarisa kunofanira kubhadharwa pakuchenesa, kuvhara pamusoro kunofanira kunge kune parafini yakajeka, uye gasket haifaniri kuwira pasi.
Ivhavha inoda kuisa bypass valve nheyo uye Settings? Isu dzimwe nguva tinoona mamwe mavharuvhu akakura mune mamwe mapaipi, uye pane nguva dzose mavharuvhu e-bypass akaiswa. Sei izvi? Basa rayo guru nderei? Mumamiriro ezvinhu api inoda kuiswa? Ndeipi dhayamita yevhavhavha yebypass yemidziyo inoenderana? Muchokwadi, iyo bypass valve yakaiswa mupombi, uye basa rayo rinogona kukamurwa kuita mapoinzi maviri zvakazara: imwe ndeyekuita basa rekudzivirira (kuenzanisa kudzvanywa pamigumo yese), imwe ndeye emergency standby!
Isu tinopota tichiona mamwe mavharuvhu akakura mune mamwe mapaipi, uye pane nguva dzose mavharuvhu e-bypass akaiswa. Sei izvi? Basa rayo guru nderei? Mumamiriro ezvinhu api inoda kuiswa? Ndeipi dhayamita yevhavhavha yebypass yemidziyo inoenderana?
Muchokwadi, iyo bypass valve yakaiswa mupombi, uye basa rayo rinogona kukamurwa kuita mapoinzi maviri zvakazara: imwe ndeyekuita basa rekudzivirira (kuenzanisa kudzvanywa pamigumo yese), imwe ndeye emergency standby!
Kutanga, iyo inodzivirira maitiro, inogonawo kunzi chiyero chekudzivirira chevhavha huru, kudzivirira vheji isati yasvika uye mushure mekudzvinyirira kwakakura zvakanyanya, uye kukonzeresa kuvhurika, vharafu haina kunaka kuvhurika, kunyanya mune dzimwe. hombe caliber kana high pressure pipeline. Usati wavhura pombi yekumanikidza yakakwira kuburikidza neiyo bypass valve pressure relief, kuitira kuti udzivise high pressure nekukasira inrush, kuumbwa kwekukanganisa papombi pazasi pevharuvhu. Kana kuti mutsauko wekumanikidza pakati pemigumo miviri yevharuvhu yakakura kwazvo, torque yekuvhura yakakura kwazvo, kuitira kudzivirira kukuvara kwetorque kuvharuvhu, bypass pressure relief usati wavhura vharuvhu.
Vaviri, basa rekukurumidzira, sepombi yekumira yekushandisa, iyo yakakura mukana ndeyekuti kana iyo huru vharafu yakundikana, kana kudiwa kwekugadzirisa uye kugadzirisa, unogona kuvhura iyo bypass vharafu kutenderera, uye haina kukanganisa yakajairika kugadzirwa.
Kunyangwe iyo valve inoda kuiswa nebypass valve chaiyo zvinodiwa uye Settings*kureva)
2.5mpa giredhi, DN400 kana pamusoro; 4.0mpa giredhi, DN250 kana pamusoro; 6.4mpa giredhi, DN200 kana pamusoro; 10MPa giredhi, DN150 kana pamusoro;
DN100~DN200 vharafu, pombi yokunzvenga uye bypass valve yeDN20; DN250~DN600 vharafu, pombi yokunzvenga uye bypass valve yeDN25; Pamavharuvhu ari pamusoro peDN600, pombi yekunzvenga uye vharafu inodarika DN40.
