Specific embodiment
The present invention is the device that a kind of multiply air-flow is switched fast direction, is worked under different operating modes with simulated experiment object
Situation.It is illustrated in figure 1 the structural representation of device, including shell 1 and pumping board 2, shell 1 plays whole device and experiment system
The effect that system connects.Shell 1 is the T-shaped structure of hollow, and both sides are connected with the horizontal pipeline 4 of experimental system respectively, shell 1
Top is provided with two bases 3 (see Fig. 2), is respectively used to connect flue and air duct.Pumping board 2 is slidably disposed in
In the hollow chamber of shell 1, Fig. 3-5 shows the topology view of pumping board 2 from different perspectives, and pumping board 2 is integrated T-shaped to be taken out
Plate, including riser 21 and top board 22, pumping board 2 is also hollow, and the top of pumping board 2 and bottom are provided with labyrinth seal groove 23, uses
To completely cut off air-flow and to reduce friction.The middle part of riser 21 is provided with opening 211 in order to circulation airflow, and top board 22 is provided with two through holes
221, it is located at the both sides of riser 21 respectively, can connect with the base 3 on shell 1, opening 211 and through hole 221 in the vertical direction
Stagger setting.Cooling pipe also can be provided with, including the cooling pipe entrance 24 positioned at riser 21 bottom with positioned at top board in pumping board 2
Cooling pipe outlet 25 on 22.Pumping board 2 and shell 1 good seal, the cooling water of internal flow can cool down pumping board to be prevented from becoming
Shape.
The working method that the multiply air-flow of the present invention is switched fast the device in direction is as follows:
The effect of the present invention is, needs moment to change work for a period of time when experimental subjects works under some operating mode
During state, pull pumping board, the air-flow under another operating mode soon can flow counterflow through experimental subjects, after reaching certain time, will
Pumping board is return in situ, and experimental subjects is returned to initial working condition, and so circulation can be switched fast the work shape of experimental subjects
State, thus the working condition under simulated experiment object real working condition, obtains performance under its real work state.Specifically, when taking out
When plate is located at the first working condition, the side of shell 1 is separated by the riser 21 of pumping board 2, also will experimental system horizontal pipeline 4
Cut-off, now the through hole 221 on top board 22 connects with the base 3 on shell 1, the flue that is, two bases are respectively communicated with
Air duct and the pipeline communication of horizontal pipeline 4 both sides, flue gas stream and air draught circulate to different directions respectively.Work as pumping board
Positioned at the second working condition when, the horizontal pipeline 4 of the base 3 on shell 1 and experimental system is separated by the top board 22 of pumping board 2, this
When riser 21 on opening 211 make two sides connection of shell 1, that is, so that horizontal pipeline 4 is connected.
The cooling circulating water road of pumping board is one-way flow, and inlet pipeline and outlet pipeline will not be short-circuit, so cooling water
Enter inlet/outlet from import to discharge, realize preferable cooling effect.
The top of pumping board and bottom are designed with labyrinth seal groove, to completely cut off the circulation between different air-flows, realize relatively
Good sealing, seal groove also acts the effect reducing friction, because the frictional force of face contact is than linear contact lay frictional force more
Greatly, the frictional force of pumping board push-and-pull can be greatly reduced using labyrinth seal groove, improve and run fluency and reliability.
The push-and-pull of pumping board is to be realized by the mechanism of rectilinear path along with the switching of air-flow working condition, both can be with people
Push and draw, it would however also be possible to employ Direct Travel operated pneumatic valve, or adopt straight stroke electric valve.Specifically chosen can be by field condition
And cost determination.
The preferred embodiment of the present invention described in detail above.It should be appreciated that the ordinary skill of this area need not be created
The property made work just can make many modifications and variations according to the design of the present invention.Therefore, all technical staff in the art
Pass through the available technology of logical analysis, reasoning, or a limited experiment under this invention's idea on the basis of existing technology
Scheme, all should be in the protection domain being defined in the patent claims.
