Description
Technical field
The utility model is related to material transfer valves, more particularly to millstone type material conveying valve, belong to valve technology field.
Background technology
Millstone type material conveying valve is a kind of Special valve applied in power plant ash disposal system, can be mounted on and save coal
The stations such as device, ash bucket, the feed inlet of storehouse pump, discharge port, switching exhaust, unimpeded.In the prior art, most of abrasive disk type material is defeated
Valve shaft lower end is sent rotatably to be fixedly supported on the inner surface of valve body, the practicality if patent publication No. is CN202186660U is new
Dustproof millstone type material conveying valve with rotating shaft disclosed in type, for details, reference can be made in this application text claim 1, specification and
Figure of description part；For another example patent publication No. is the dust-proof abrasive disk type of piston rod disclosed in the utility model of CN202149274U
Material transfer valve, for details, reference can be made to claims, specification and the Figure of description parts in this application text；This knot
Structure, valve deck and valve body shaft hole concentricity require high, process costs height.For another example patent publication No. is the practicality of CN206449219U
The novel disclosed wear-resisting moushroom valve of anti-accumulation, for details, reference can be made to Figure of description parts.Abrasive disk type material conveying disclosed above
Pivot structure used by valve (mill valve) is easy to lead to its shaft lower end " astringent " or even card because of coal ash, the dust in valve chamber
Extremely, it for this purpose, to ensure valve service life, is largely devised in shaft bottom end using the mill valve of the class formation corresponding close
Sealing assembly.Seal assembly can play the role of corresponding to a certain extent, avoid shaft lower end " astringent " or even stuck ask
Topic, still, seal assembly being added and increasing manufacturing cost, and using a period of time, seal assembly aging also will appear stuck
Phenomenon.Nor convenient for the demolition and maintenance of later stage valve hinges, caused drawback is also fairly obvious；Further, since
Shaft lower end is fixedly supported on valve interior surface, and therefore, it is necessary to the design of the position of shaft and valve body are corresponded in valve interior surface
Integrally formed support rim, in prior art, which usually requires to be integrally cast with valve body, either from system
It is not a kind of ideal structure design for causing in terms of the convenience of this or die sinking.
In addition, existing millstone type material conveying valve carries valve body.Valve deck connect to form valve chamber with valve body, and material is from valve
The flange hole covered enters valve chamber, from the laxative remedy flange aperture output on valve body.It is identical to import and export flange diameter.In case of conveyance conduit is big
In lower flange bore dia, then needs to change pipe diameter, connected using transition Taper Pipe, make its connecting flange size and valve body lower flange
Bore dia is identical.Using such tapered pipeline, the loss of medium discharge pressure is big, increases the power of air compressor machine, and pipeline becomes
Diameter increases valve installation cost.Therefore, in order to adapt to the demand of different-diameter conveyance conduit configuration, there is an urgent need for a kind of no bodies
Valve, i.e. the material transfer valve without valve type, the valve do not contain valve body, and shaft may be supported on valve deck, can be straight by valve deck
It is connected in succession in conveyance conduit either equipment.
Invention content
