Abstract
The utility model discloses the unidirectional air door autocontrol valve of a kind of multi-disc, it comprises connecting base (6), airduct (5), blade seat (1); Above-described blade seat (1) is positioned at airduct (5) inside, and blade seat (1) and airduct (5) dead in line; On blade seat (1), be provided with upper blade (2), Leaf (3), lower blade (4), upper blade (2) keeps one degree of freedom to be arranged on blade seat (1) by upper coupling shaft (21), it is upper that Leaf (3) keeps one degree of freedom to be arranged on blade seat (1) by middle coupling shaft (31), and lower blade (4) keeps one degree of freedom to be arranged on blade seat (1) by lower coupling shaft (41).The utility model provides a kind of multiple-blade flexible rotating, and wind direction can only carry out unidirectional delivery and the unidirectional air door autocontrol valve of multi-disc that designs.
Description
Technical field
The utility model relates to valve field, relates in particular to the unidirectional air door autocontrol valve of a kind of multi-disc.
Background technique
Air-valve is widely used in industrial and mineral, civil building heating ventilation air-conditioning system, and air mass flow is regulated, and is to realize under various environment controlling one of key equipment of air vent mode.Its main feature be go slick, noise is low, amount of leakage is little, operating temperature region is wide, reliable in structure, safe ready.
In lime slaker dust pelletizing system, need to arrange blower fan, and need to be provided with standby fan, standby fan needs one-way cock to control, and prevents the gas leakage of standby fan pipeline, thereby need to close backup line.Air-valve in traditional lime slaker dust pelletizing system often adopts mechanical type locking, does not automatically lock valve.
Model utility content
The utility model provides a kind of multiple-blade flexible rotating, and wind direction can only carry out unidirectional delivery and the unidirectional air door autocontrol valve of multi-disc that designs.
For realizing above object, the technical solution adopted in the utility model: the unidirectional air door autocontrol valve of multi-disc, is characterized in that it comprises connecting base (6), airduct (5), blade seat (1); Above-described blade seat (1) is positioned at airduct (5) inside, and blade seat (1) and airduct (5) dead in line; On blade seat (1), be provided with upper blade (2), Leaf (3), lower blade (4), upper blade (2) keeps one degree of freedom to be arranged on blade seat (1) by upper coupling shaft (21), it is upper that Leaf (3) keeps one degree of freedom to be arranged on blade seat (1) by middle coupling shaft (31), and lower blade (4) keeps one degree of freedom to be arranged on blade seat (1) by lower coupling shaft (41).
The utility model beneficial effect: owing to being provided with upper blade, Leaf, lower blade on blade seat, three symmetrical Leaf positional distribution modes can be good at carrying out blade opening and closing.Three vane collocation can alleviate the weight of blade, prevent that dust covers on blade in special operation condition situation, cause blade rotation difficulty.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the plan view that blade and blade seat cooperatively interact.
Fig. 3 is wind direction while making progress, blade closed condition schematic diagram.
Fig. 4 is wind direction when downward, blade opening state schematic diagram.
Embodiment
By reference to the accompanying drawings the utility model is done to further explaination.As shown in Figure 1 and Figure 2, Standard relation of the present utility model: the unidirectional air door autocontrol valve of multi-disc, it comprises connecting base 6, airduct 5, blade seat 1; Above-described blade seat 1 is positioned at airduct 5 inside, and blade seat 1 and airduct 5 deads in line; On blade seat 1, be provided with upper blade 2, Leaf 3, lower blade 4, upper blade 2 keeps one degree of freedom to be arranged on blade seat 1 by upper coupling shaft 21, Leaf 3 keeps one degree of freedom to be arranged on blade seat 1 by middle coupling shaft 31, and lower blade 4 keeps one degree of freedom to be arranged on blade seat 1 by lower coupling shaft 41.
Working principle of the present utility model: as shown in Figure 3, when wind direction is during to blowing up, upper blade 2, Leaf 3, lower blade 4 are all in closed condition.As shown in Figure 4, when wind direction is during to blowing down, upper blade 2, Leaf 3, lower blade 4 are all in opening state.
Applied specific case herein principle of the present utility model and mode of execution are set forth, the explanation of above example is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or without improving, the design of model utility and technological scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
