Description
Technical Field
The utility model relates to a pneumatic air door technical field especially relates to a controllable pneumatic air door of slew velocity.
Background
In the environmental protection industry, dampers are used in many processes, a large portion of which use pneumatic actuators. Pneumatic air door's advantage is to open and close rapidly, and the moment of torsion is big, but when using great air door (if more than 1 meter of diameter), when using the cylinder to promote the air door and rotate, because the rotational speed is very fast, and air door body quality is big, causes the rotation impulse great, and when the air door reachs spacingly, the air door can't stop rotating immediately, because inertia can continue to rotate certain angle and up to stopping of mechanical part, therefore can lead to the fact the harm to air door body or cylinder mechanical part to influence operation safety.
Therefore, the air door capable of controlling the flow rate of compressed air is provided to reduce the rotation speed of the air door, further reduce the rotation impulse, reduce the collision to mechanical parts when reaching the stroke end of the air cylinder, increase the safety performance of equipment, and is a problem to be solved by a person skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a controllable pneumatic air door of slew velocity to current pneumatic air door because the rotational speed is very fast, and the air door can't stall immediately when the air door reachs spacingly, rotates the great problem that can cause the harm to air door body or cylinder mechanical part of impulse, provides.
In order to achieve the purpose, the utility model adopts the technical proposal that:
the pneumatic air door with the controllable rotating speed comprises an air door main body, an air cylinder and a regulating air valve; the two regulating air valves are respectively arranged on an air inlet pipeline and an air outlet pipeline of the cylinder and can respectively regulate the air inflow and the air discharge of the cylinder; the air door main part includes disc air door and pivot, the disc air door is fixed in the pivot, the cylinder with pivot one end links to each other, in order to drive the disc air door rotates.
Further, the air cylinder is a piston cylinder, and the piston cylinder is rotatably connected with the rotating shaft of the air door main body through a connecting component.
Further, the connecting part is of an L-shaped structure.
Further, the cylinder is a rotary cylinder, and the rotary cylinder is connected with the rotating shaft.
Furthermore, the air door main body further comprises a cylindrical outer cover, and two ends of the rotating shaft are rotatably fixed on the cylindrical outer cover.
Further, the inner wall of the cylindrical outer cover is provided with a refractory material.
The utility model adopts the above technical scheme, compare with prior art, have following technical advantage:
the utility model discloses a controllable pneumatic air door of slew velocity can control compression air flow rate, and the slew velocity of air door slows down, and then reduces and rotates the impulse, has also less to the collision of mechanical part when cylinder stroke terminal point, has increased the security performance of equipment.
