Dɛn ne Nsɔano nnyinasosɛm a ɛwɔ ntontom valve abiɛsa a ɛyɛ nwonwa no mu?

Nsɔano nnyinasosɛm a ɛwɔ abiɛsa a ɛyɛ nwonwa no mu .Butterfly valve .no gyina ne soronko abiɛsa eccentric nhyehyɛe nhyehyɛe so, a ɛyɛ elliptical sealing surface denam nkabom a ɛyɛ eccentricities abiɛsa, achieving torque sealing of the metal hard sealed butterfly valve ne titiriw no siesie friction damage ne leakage haw ahorow a atetesɛm butterfly valves.

Ne titiriw no, Nsɔano nnyinasosɛm a ɛwɔ abiɛsa a ɛyɛ nwonwa no mu .Butterfly valve .Nsɛm titiriw a edidi so yi ka ho:

Triple Eccentric Structure: Axis a ɛwɔ valve stem a ɛwɔ triple eccentric butterfly valve no mu no twe ne ho fi ntontom mprɛte no mfinimfini ne nipadua no mfinimfini nyinaa ho, na valve seat no a ɛkyinkyini no yɛ angular sealing structure a ɛne valve body no kwan no axis no yɛ. Saa nhyehyɛe yi hwɛ hu sɛ ɛkame ayɛ sɛ akasakasa biara nni valve mprɛte ne valve nkongua no ntam bere a wɔrebue na wɔreto ntontom valve no mu no, na ɛma ɔsom asetra ne valve no ano a ɛyɛ adwuma no tu mpɔn kɛse.

Torque sealing mechanism: Nsɔano a ɛwɔ eccentric butterfly valve abiɛsa no mu no nyɛ gyinabea a wɔde hyɛ mu bio, na mmom torque sealing. Sɛ wɔto butterfly valve no mu a, nhyɛso a ɛwɔ nsɔano abien a ɛwɔ ne sealing pair no ntam no yɛ nea ɛnam driving torque a wɔde gu valve no dua no so no so na ɛba. Saa sealing mechanism yi tua tolerance zone a ɛda shaft sleeve ne valve body ntam no so ka yiye, ne elastic deformation a ɛwɔ valve stem no mu wɔ nhyɛso a ɛwɔ ntam no ase, na esiesie sealing problem a ɛwɔ bi-directional exchange of medium transportation in valves no.

Non frictional contact of sealing surface: Nsɔano a ɛwɔ abiɛsa a ɛyɛ nwonwa no mu .Butterfly valve .yɛ cone structure a ɛyɛ slanted, na ɛno nti valve plate sealing surface no nsusuwii yɛ asymmetric fi soro kosi ase. Sɛ wobue butterfly valve no fi 0 ° kosi 90 ° a, valve mprɛte no a wɔde bɛkata so no bɛtwe afi valve no nkongua no so wɔ bere a wɔabue no mu; Sɛ wɔto mu fi 90 ° kosi 0 ° a, bere a wɔato mu nkutoo no, valve mprɛte no a wɔde hyɛ mu no bɛkata so na amia valve no nkongua no so. Saa nhyehyɛe yi hwɛ hu sɛ akasakasa biara nni valve no nkongua ne nea wɔde hyɛ ntontom mprɛte no so no ntam, na eyi nea ebetumi aba sɛ ɛbɛwe ne nea ɛretu no afi hɔ.

Adjustable sealing performance: Wobetumi asiesie sealing pressure ratio a ɛwɔ eccentric butterfly valve abiɛsa no mu wɔ ɔkwan a wɔpɛ so denam akyi karka torque a wɔbɛsesa so, na ɛnam so ama sealing adwumayɛ a ɛwɔ eccentric butterfly valve abiɛsa no mu no atu mpɔn na ama ne som asetra akɔ soro kɛse.
