Abstract
The utility model provides an air chute flow control valve, shell including last casing and inferior valve body group one -tenth, the axle is installed at last casing both sides face through rolling bearing unit, the valve plate is connected epaxial, rotation through the axle is opened, close, the valve plate is the arc valve plate, the arc valve plate passes through former and hub connection, in arc valve plate closed condition position, install a seal receptacle, opening in the middle of the seal receptacle, seal all around, and fix at epitheca side face, the cambered surface of seal receptacle is coincide with the cambered surface of arc valve plate, the rubber seal strip is installed with arc valve plate contact position all around to the seal receptacle, make arc valve plate and valve seat seal tight. The big I of arc valve plate opening angle realizes flow control, and opening angle can realize through manual or electronic angle executor, and is simple and convenient, slide valve, flap valve hourglass material problem before the seal receptacle has thoroughly been solved with the combination of arc valve plate.
Description
Technical field:
For a kind of device of material diversion, dosing on the air flume that the utility model relates to granular material conveying, gate valve, the Flap valve of other type before its inside, outside seal performance are better than.
Background technique:
At present, diverter valve air flume used, stop valve, flow control valve adopt gate valve, Flap valve mostly.
Gate valve is on air flume upper shell, open a notch, then a shoe brake plate is put into, flashboard can adopt the upper and lower straight line motion of manual, electronic, pneumatic realization to promote, land, controlling the flow direction or the flow of granular material, there is gap and adopts Stamping Steel Ribbon press seal in flashboard and upper shell notch.But there is following defect in this device: 1. because of its working principle of air flume be utilize the kinetic energy of air-flow make bulk granular material be state of suspension with air-flow along Cemented filling, malleation is there is in skewed slot housing, flashboard and upper shell notch seal very difficult, powder is very easily caused to overflow from notch, befouling environment; 2. flashboard end directly drops in air-permeable layer, and time one length easily causes air-permeable layer to damage; 3. still there is gap in flashboard and upper shell sidewall, thoroughly can not block material.
Flap valve installs one piece of turnover panel in skewed slot upper shell inside, and drive turnover panel to rotate by an axle through upper-lower casing, the rotation of axle can adopt manual, electronic, pneumatic realization to open or close valve plate, realizes the flow direction or the flow that control granular material.This device overcomes fluting on housing and occurs leaking material problem, but the seal between valve plate and upper shell not easily ensures, may occur leaking material phenomenon when valve plate is closed.
Model utility content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of device, gate valve, the Flap valve of other type before its inside, outside seal performance are better than.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of air flume flow control valve, comprise the shell of upper shell and lower shell body composition, axle is arranged on upper shell bi-side by rolling bearing units, valve plate is connected on axle, by rotating opening, the closedown of axle, it is characterized in that: described valve plate is arc valve, and arc valve is connected with axle by former.
In arc valve closed condition position, install a sealing seat, sealing seat middle opening, all round closure, and be fixed on upper shell side, the cambered surface of sealing seat and the cambered surface of arc valve are coincide.
Sealing seat surrounding and arc valve contact position install rubber weather strip, make arc valve and valve base sealing tight.
The utility model beneficial effect is: the large I of arc valve opening angle realizes flow control, opening angle can manually or electronic angle final controlling element realize, simple and convenient; The combination of sealing seat and arc valve thoroughly solves former gate valve, Flap valve leaks material problem.
Accompanying drawing illustrates:
Fig. 1 is that the utility model faces structural representation;
Fig. 2 is A-A schematic diagram in the utility model Fig. 1;
Fig. 3 is the utility model elevation cross-sectional view.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
A kind of air flume flow control valve as shown in Figure 1, Figure 2 and Figure 3, comprise the shell of upper shell 1 and lower shell body 2 composition, axle 3 is arranged on upper shell bi-side by rolling bearing units 4, valve plate 5 is connected on axle, by rotating opening, the closedown of axle, wherein valve plate is arc valve, and arc valve is connected with axle by former 6.
In arc valve closed condition position, install a sealing seat 7, sealing seat middle opening, all round closure, and be fixed on upper shell side, the cambered surface of sealing seat and the cambered surface of arc valve are coincide.
Sealing seat surrounding and arc valve contact position install rubber weather strip 8, make arc valve and valve base sealing tight.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
