The coupled exhaust valve adopts the structure that a base (5) is connected with brattices (4) to form a fan frame; wind plates (1) are positioned in the fan frame in groups; two horizontal ends of each wind plate are fixedly connected to a shaft (2); the shafts (2) are movably matched with shaft sleeves (3) on the brattices (4); a hinge seat fixedly connected with the lower ends of the wind plates in the same group is movably matched with a hinge shaft, and the hinge seat and the hinge shaft are arranged on the same pull rod (8); and each group of wind plates is provided with at least one spacing bean (7) which is in the same direction as the wind plates and fixedly connected to the upper ends of two opposite brattices.
Description
Technical field：
The utility model is related to a kind of twin air draft valve gear of air-conditioning heat dissipation system air draft.
Background technology：
At present, for the exhaust valve of air-conditioning system, all kinds of corrupt practices creep in：Using monoblock type, aerofoil is rigidly low, open that difficult, opening angle is small, exhaust resistance is big, perishable aerofoil rotary shaft, short life, noise are big etc.；
Utility model content：
Connection formula exhaust valve, base 5 connects and composes fan frame with coaming plate 4, aerofoil 1 is located in fan frame in groups, the horizontal two ends of aerofoil are connected with axle 2, axle 2 and the dynamic cooperation of axle sleeve 3 on coaming plate 4, the free bearing being connected with the lower end of group aerofoil is moved with the hinge on same pull bar 8 to be coordinated, and every group of aerofoil has at least one spacing beam 7 in the same direction with aerofoil, and spacing beam 7 is connected in relative two coaming plate upper ends.
It is fluted on coaming plate, under have a right angle step, base is right angle section bar, and the groove that right angle step and the base of coaming plate are connected and composed on rhone around, coaming plate has hole to be connected with axle sleeve 3.
There are the angular lower notches of in the same direction two on aerofoil, the outer wall of upper groove coordinates with spacing beam 7, be connected axle 2 in low groove.
Fan frame is divided into left and right frame by two coaming plates symmetrically connected, the right angle step of two coaming plates symmetrically connected respectively erects wall with the one of rhone 6 and is connected, and left and right frame is respectively connected with one group of aerofoil.
Two groups of aerofoils respectively have a spacing beam 7, and aerofoil maximum opening angle is 85 degree.
The utility model has the following advantages:
1. base is formed by six roots of sensation bending angle steel with middle rhone group weldering, the drainage problem of air-valve is solved into formed U-lag by being riveted between surrounding coaming plate and base；
2. surrounding coaming plate uses same section configuration；
3. aerofoil uses two groups, the section configuration of aerofoil has taken into full account aerodynamic principle, will be with group aerofoil series winding by a pull bar and plastic staple bolt；
4. using two spacing beams, two groups of aerofoil opening angles are adjusted respectively, its maximum opening angle is limited for 85 °, the resistance of air draft is reduced, improves ventilation efficiency；Air-valve can smoothly it be closed after a shutdown again while ensureing and reaching discharge maximum quantity of wind；The spacing beam adds and strengthens integrally-built rigidity；
5. using the axle sleeve of nylon material, making aerofoil, wear-resisting, frictional resistance is small, noise is low in motion.
The utility model is not only easy for installation, and simple in construction, is easy to manufacture, assembles, adjusts, aesthetic in appearance.Can easily it be closed again while maximum exhaust air rate is ensured, the air draft of especially suitable air-conditioning system.
