Detailed Description

The present utility model is further described below with reference to the drawings and examples, but the present utility model is not limited to the examples, and all the similar structures and similar variations using the present utility model should be included in the protection scope of the present utility model. The use of the directions of up, down, front, back, left, right, etc. in the present utility model is only for convenience of description, and is not a limitation of the technical scheme of the present utility model.

As shown in fig. 1, the improved air quantity valve comprises a shell 1, an air inlet 2 is formed in the bottom of the shell 1, an air outlet 3 is formed in the top of the shell 1, a fixed shaft 4 which is arranged in the radial direction is arranged at the bottom of the shell 1, two ends of the fixed shaft 4 are fixedly connected with the shell 1, two blades 5 are hinged to the fixed shaft 4, the two blades 5 are arranged on two sides of the fixed shaft 4, the outer side edges of the two blades 5 are connected with the inner side face of the shell 1 in a sealing fit manner, a connecting rod 6 is hinged to the upper sides of the two blades 5 respectively, the upper ends of the two connecting rods 6 are hinged to a moving block 7, a driving device is arranged above the moving block 7 in the shell 1, and the power output end of the driving device is connected with the moving block 7.

Further, the driving device comprises a fixing rod 8, the fixing rod 8 is arranged in the shell 1 along the radial direction, two ends of the fixing rod 8 are fixedly connected with the shell 1, a vertical screw rod 9 is arranged in the fixing rod 8 in a penetrating mode, the upper end of the screw rod 9 is fixedly connected with a knob 10, a threaded hole is formed in the upper surface of the moving block 7, and the lower end of the screw rod 9 is connected with the threaded hole.

Further, the shell 1 is cylindrical, and the outer side of the blade 5 is a cambered surface.

Further, the blade 5 is connected with the fixed shaft 4 through a hinge 11.

Further, the shell 1 and the blades 5 are both composed of aluminum plates. The shell 1 is not easy to generate sparks when being rubbed with external parts, the explosion-proof effect is achieved, the blades 5 are lighter and more flexible in adjustment.

Furthermore, the fixed shaft 4 is made of galvanized round steel, so that the valve internal structure is not deformed under the condition of high wind pressure.

Furthermore, the fixing rod 8 is made of galvanized steel sheet, so that the fixing rod is more stable and reliable when being impacted by the outside.

Specifically, the casing 1, the fixed shaft 4, the blade 5, the driving device, the screw rod 9, the hinge 11, the aluminum plate, the galvanized round steel, the galvanized steel sheet, and the like in this embodiment all adopt the known schemes in the prior art, and those skilled in the art will understand the schemes, and will not be described herein.

The working principle of the embodiment is as follows: in the initial state, the outer side surfaces of the two blades 5 are in sealing connection with the inner side surface of the shell 1, so that the air inlet 2 is closed. Then rotate knob 10, knob 10 drives lead screw 9 and rotates, and lead screw 9 drives movable block 7 and reciprocates, and movable block 7 passes through connecting rod 6 and drives two blades 5 and rotate, and two blades 5 draw close each other, produce the opening between blade 5 and the casing 1, make air intake 2 open, and the air current outwards blows out from two directions through the guide effect of two blades 5, reduces the difference in temperature of different positions in the space, and, this valve has two blades 5, compares with prior art's single leaf valve door, and twin blade 5 has two air-out directions, and the resistance is littleer, and the air current circulation is more smooth and easy.

When the valve is installed, different installation directions can be set, so that air flow is blown out from the left side, the right side, the upper side, the lower side or other directions.

In the embodiment, the middle of the moving block 7 adopts a tapping and molding integrated process, so that when the adjusting blade 5 is opened and closed and the air flow passes through, the valve is free from shaking and noise, and the instability of the valve caused by resonance caused by shaking is avoided.

In the embodiment, the surface of the valve adopts a galvanization process, so that the valve has the functions of corrosion resistance and service life prolonging, and conventional attachments cannot be adhered to the surface of the valve due to the smoother surface, even if a little dust is accumulated for a long time, the valve can be cleaned by using dry cloth gently.

The supporting rod also plays a limiting role, can limit the moving distance of the moving block 7, control the opening angle of the blade 5, and avoid excessive opening of the angle of the blade 5, thereby bringing irreversible damage to each part.
