Description
Technical field
The present invention relates to dedusting airduct or process gases system regions, and in particular to a kind of closed switching of wide tee
Valve.
Background technology
Existing frequently-used draft fan switching is general from air outlet tubing type, the structure of air inlet Y-shaped bypass type.
In skill gas extraction system, a pipe-line system can be from the Fans of the using and the reserved two as power, and common way is by two typhoons
Machine outlet is discharged by same chimney again after accessing a heavy caliber transverse tube, and fan outlet can first access one to avoid pipeline from shaking
Section accesses a check-valves after being flexible coupling, to prevent reverse flowing of air flows.
Aforesaid way there are problems that following:
(1) two Fans air outlet access same pipeline in, when needing to switch over, using blower fan frequency progressively under
Drop, standby fan frequency gradually rises, and standby fan check-valves can only wait until to stop or increase standby fan completely using blower fan
Primary frequency could be opened, and opening procedure is not progressively opened, but moment open a larger angle after again by
Step standard-sized sheet, so necessarily causes blast instability of flow in pipeline.
(2) phenomenon of " tacking " occurs when switching over for the using and the reserved blower fan, because two Fans are produced in switching
Raw air-flow reciprocating collision in pipeline forms resonance, can not only produce noise, and pipeline to produce after resonating and can also influence it
Service life.
(3) operation principle of general check valve is to be opened check-valves blade top by stream pressure, when pressure diminishes or wind
When machine is stopped, is conducted oneself with dignity by blade and reach the effect being automatically switched off.To reach the flexible performance of check-valves, general meeting
Reduce blade and the frictional force between blade, blade and valve body as far as possible.So high-leakage rate can be present in general check-valves.
(4) pipeline switched over using Y-shaped bypass tubular construction needs to match somebody with somebody on conventional branch road and emergency bypass pipeline
Put equivalent pipe fitting (valve, elbow, short tube class).And the valve of conventional branch road and the valve of emergency bypass cannot be accomplished
It is consistent with blower fan open and close frequency.
The content of the invention
It is an object of the invention to the problem above for overcoming prior art to exist, there is provided a kind of closed switching of wide tee
Two valves are integrated into a switching valve by valve, the present invention, have not only saved the cost of valve, save site space, and
Solve " tacking " phenomenon that two Fans are interfered with each other in switching action.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is achieved through the following technical solutions:
A kind of closed switching valve of wide tee, it includes valve body and the valve member coordinated with the valve body, the valve
Door component is arranged at the valve inner air-flow openings,
The valve member includes:Revolved by the active as the active rotation axle of the valve member drive shaft, two
Driven rotary shaft that rotating shaft is rotated, the blade being separately positioned in the active rotation axle and driven rotary shaft, the master
Dynamic rotary shaft is set with the driven rotary shaft in inverted triangle machine, passes through between the active rotation axle and the driven rotary shaft
Linkage bar connection, the active rotation axle drives the driven rotary shaft to rotate by the linkage bar;
The valve inner is provided with band, and the band is arranged at the valve inner air-flow openings, described
Band coordinates with the blade shape, and the band seals the gap between the valve body and the blade.
Further include, open up fluted in the axial direction of the driven rotary shaft, the groove is arc groove.
Further include, the edge of the blade is provided with runner sealing bar, the active rotation axle rotarily drive it is described from
Dynamic rotary shaft rotation, the blade is attached on the band, and the runner sealing bar is attached in the groove.
Further include, the linkage bar is " V " character form structure, and two free ends of the linkage bar are respectively connecting to institute
State in driven rotary shaft, the active rotation axle is connected at the joint of the linkage bar.
Further include, the active rotation axle and driven rotary shaft are connected by linkage block with the linkage bar, institute
State and be arranged with axle sleeve in active rotation axle and driven rotary shaft.
Further include, the valve body is " Y " character form structure, the valve body includes three tubular structures, three tubulose knots
Structure intersection is valve body triangle, and the valve member is arranged in the valve body triangle.
Further include, three tubular structures are respectively the first tubular structure, the second tubular structure, the 3rd tubulose knot
Structure, the band, the first tubulose knot are provided with first tubular structure and the openings of second tubular structure
The band is provided with structure and the openings of the 3rd tubular structure.
Further include, the openings of first tubular structure and the second tubular structure be it is circular or square, it is described
First tubular structure is circular or square with the openings of the 3rd tubular structure.
Further include, flange is equipped with the tubular structure.
The beneficial effects of the invention are as follows:
, used as drive shaft, the rotary shaft of other valve blades is used as driven for valve mechanism active rotation axle of the invention
Axle, the blade on active rotation axle, as common blade, is both the blade of conventional branch trackside and the blade of emergency bypass side, its
Remaining all passive blades all do pendulum leaf and act by the driving of the bar that links with active rotation axle blade.
Sealed by band between blade and valve body, sealed by runner sealing bar between blade and blade,
In the present invention, the caulking gum between blade and valve body and between blade and blade is not squeezed by rubber friction after control room gap
Press to block air-flow, but the rotation of blade side is attached on band, the sealing strip on blade is attached at driven rotary shaft
On reserved groove.When blade leans against emergency bypass side, the air-flow of conventional branch trackside can apply pressure, blade and valve on blade
Fitting between body, blade and blade can increase with pressure and increasingly tightlier, when needing to switch over, rubber components also will not
Frictional force is produced with valve body and blade.
Two valves are integrated into a switching valve in the present invention, valve cost has not only been saved, site space is saved,
And solve " tacking " phenomenon that two Fans are interfered with each other in switching action;Valve body uses the structure of Y-shaped threeway more
Beneficial to the pressure loss, and the only one of which drive shaft in switching is reduced, all of blade is all overall in the presence of the bar that links
Action, the action of blade depend entirely on where the frequency on collateral road just, whole switching action is more steady.
The pressure loss of the smaller blower fan of angle of blade lean when opening and closing time valve disc piece is pushed up is smaller, and conventional check valve is opened
When all of blade all in horizontal level, check-valves blade top can only be opened by air-flow when blower fan needs and opens passage.This
Invention valve then avoids problems, can also easily be switched over very much in the presence of external balance hammer is not needed dynamic
Make.
