9. Rising Stem Knife Gate Va e is widely used and enjoy good reputation.
QB metal seated knife gate va e, QB Non Rising Stem WCB Material Knife Gate Va e, is a new type knife gate va e whose seat is fixed up on the body. The metal seat ring moves ladderlike with body, and moves concavo-convex with seat. QB Rising Stem Knife Gate Va e is with O type seat ring is set between the metal seat ring and the seat, and a seat ring is at the joint of the seat and the body. Some dollops which are casted together with the body at the bottom, on the gate there also is bevel to fit the dollops. When the gate closes to the bottom of the body, the dollops extrude the gate to impinge the metal seat. This structure breaks the shortage of can’t be taking pressure test for the metal seat, evidently improve the effect of pressurizing. The type va e is suitable for the medium of granule.
1, Seal by structural ceramics, can prevent solid grain scour to seal face, wear, ensure va e seal
2, single seat design can effectively prevent the deposition of slag and jam.
3, single seat, one-way sealing.
4.the va e plate design is flat with blade shape, easy to cut materials or granular media, the va e
plate close to seal face, shave their the quality and slag particles which are stick to seal face and
va e plate , short type structure design makes the body more compact structure.
5. choose packing also adopt the ptfe braid rope, seal depth design enough sealing and reliable.
7. the va es are suitable for power plant dry ash system, the warehouse pump material out conveying,
also can be used in mining, paper making, chemical industry etc of all kinds have worn slag, cinders,
and slag water mixture medium in pipelines as an opening and closing.Nominal pressure IS 1.0 MPa,
applicable temperature less than 80 °C.
8. the va e seal adopt double seal structure type, soft seal + metal seal, metal sealing layer effective
protection soft sealing layer, increase the life of the seal; The va e body and cover adopt WCB steel
castings, filler/packing used high quality wear-resisting mixed Flexible
