Description
Technical field
The utility model relates to a kind of testing equipment, the test unit of the butterfly valve of one of critical component in especially a kind of cement equipment, specifically a kind of self-adapting type butterfly valve function wind tunnel test device.
Background technology
Self-adapting type butterfly valve (seeing Chinese patent ZL200610038758.X for details) is a kind of simple in structure; Comb bed volume damper easy to use; Be widely used in the 4th generation, the 5th generation cooling machine, need regulated just valve block according to the requirement of design intake and can reach optimum efficiency when this butterfly valve used, owing to lack corresponding test unit; Causing at present mostly is the parameters such as weight, angle, gap of rule of thumb confirming valve block with Theoretical Calculation; Therefore, designing the device that can accurately check labyrinth plate ventilation is to improve self-adapting type butterfly valve result of use, accurately controls the key of intake, energy savings.
Summary of the invention
The purpose of the utility model is to be directed against existing self-adapting type butterfly valve because of lacking the problem that corresponding test unit causes accurately confirming ventilation, designs a kind of self-adapting type butterfly valve function wind tunnel test device that can accurately measure its ventilation.
The technical scheme of the utility model is:
A kind of self-adapting type butterfly valve function wind tunnel test device; It is characterized in that it mainly is made up of tunnel body for wind blast regulation valve door 1, test air tunnel body 2, resistance labyrinth plate 3, self-adaptation butterfly valve body 4, self-adaptation butterfly valve swing valve block 5, centrifugal blower 6 and butterfly valve turning joint 7, centrifugal blower 6 links to each other with the bottom air inlet of test air tunnel body 2 through the ventilating duct that seals.Tunnel body for wind blast regulation valve door 1 is positioned at the top of test air tunnel body 2; Resistance labyrinth plate 3 is installed in the middle part of test air tunnel body 2, the top of said air inlet; Self-adaptation butterfly valve body 4 is installed in the bottom of resistance labyrinth plate 3; Self-adaptation butterfly valve swing valve block 5 is installed in the self-adaptation butterfly valve body 4, and the upper end hinge of self-adaptation butterfly valve swing valve block 5 is contained in the butterfly valve turning joint 7 that is arranged in self-adaptation butterfly valve body 4.
Described test air tunnel body 2 is the airtight casings that are welded into by steel plate.
The beneficial effect of the utility model:
The utility model provides directly perceived for check self-adapting type butterfly valve changes the effect of regulating charge flow rate automatically to labyrinth plate resistance power.Make that corresponding culvert number relation comes into plain view between resistance on the plate of labyrinth (kpa) and the valve charge flow rate (m3/min).
The utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 1 institute method.
A kind of self-adapting type butterfly valve function wind tunnel test device; It mainly is made up of tunnel body for wind blast regulation valve door 1, test air tunnel body 2, resistance labyrinth plate 3, self-adaptation butterfly valve body 4, self-adaptation butterfly valve swing valve block 5, centrifugal blower 6 and butterfly valve turning joint 7; Described test air tunnel body 2 is the airtight casings that are welded into by steel plate, and centrifugal blower 6 links to each other with the bottom air inlet of test air tunnel body 2 through the ventilating duct of sealing.Tunnel body for wind blast regulation valve door 1 is positioned at the top of test air tunnel body 2; Resistance labyrinth plate 3 is installed in the middle part of test air tunnel body 2, the top of said air inlet; Self-adaptation butterfly valve body 4 is installed in the bottom of resistance labyrinth plate 3; Self-adaptation butterfly valve swing valve block 5 is installed in the self-adaptation butterfly valve body 4, and the upper end hinge of self-adaptation butterfly valve swing valve block 5 is contained in the butterfly valve turning joint 7 that is arranged in self-adaptation butterfly valve body 4.
The principle of work of the utility model is:
After centrifugal blower 6 was opened, air-flow got into test air tunnel body 2 bottoms, and through the gap intake resistance labyrinth plate 3 of self-adaptation butterfly valve swing valve block 5 with self-adaptation butterfly valve body 4, through the air-flow of resistance labyrinth plate 3, behind tunnel body for wind blast regulation valve door 1, discharged.
When regulating tunnel body for wind blast regulation valve door 1, the resistance of the air-flow through resistance labyrinth plate 3 can change, and the valve block of self-adaptation butterfly valve swing simultaneously 5 can be around butterfly valve turning joint 7 swings.
When tunnel body for wind blast regulation valve door 1 aperture diminishes; The resistance of the air-flow through resistance labyrinth plate 3 increases; The aperture that self-adaptation butterfly valve swing valve block 5 rotates around butterfly valve turning joint 7 can become big automatically, also makes the self-adaptation butterfly valve body 4 of flowing through big with the gap change of self-adaptation butterfly valve swing valve block 5.
When tunnel body for wind blast regulation valve door 1 aperture becomes big; The resistance of the air-flow through resistance labyrinth plate 3 reduces; The aperture that self-adaptation butterfly valve swing valve block 5 rotates around butterfly valve turning joint 7 diminishes automatically, also makes the gap smaller of flow through self-adaptation butterfly valve body 4 and self-adaptation butterfly valve swing valve block 5.
Can check the self-adapting type butterfly valve to regulate the effect of air-flow automatically through this device.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
