Combined low-power-consumption ventilation valve

Abstract

The invention relates to a combined low-power-consumption ventilation valve, and belongs to the technical field of ventilation valves. The valve comprises a dustproof assembly, a shell assembly, a sealing disc assembly, a circuit board assembly, an electromagnet assembly, a linear motor assembly and a waveguide plate assembly. The shell assembly comprises an air duct main shell, an outlet flow guide shell and a mounting support. A control box is arranged on the air duct main shell and used for mounting the circuit board assembly. The circuit board assembly comprises an electromagnet voltage reduction module and a linear motor circuit board. The circuit board assembly is placed in the control box of the air duct main shell and fixed with screws. The electromagnet assembly comprises an armature, a protective cover, an electromagnet coil and a guide block part. According to the combined low-power-consumption ventilation valve, the requirement for the air passing area can be met under the condition with high air volume, the size is small, the weight is low, the valve can be opened or closed instantly, and the combined low-power-consumption ventilation valve has the power-losing self-closing function, has the sand prevention and low-temperature resistance functions and has certain anti-electromagnetic interference performance.

Description

technical field [0001] The invention relates to a combined low power consumption ventilation valve, which belongs to the technical field of ventilation valves. Background technique [0002] The mouth of the ventilation pipe system will be installed with a valve that controls the opening and closing of the mouth of the system. Due to the contradiction between the stroke of the spring and the area of ​​the wind, it is impossible to use only the spring to realize the opening and closing function of the valve for large air volume on the market. Most of the valves in the world are too large in volume and weight or the actuator is relatively large, and the occupied space is too large, which is not conducive to miniaturization design. Moreover, the execution time of such valves is long, which is not conducive to the rapid opening and opening of the ventilation system mouth. In addition, the most important thing is that the valves on the market do not have the function of self-closi...

[0002] The mouth of the ventilation pipe system will be installed with a valve that controls the opening and closing of the mouth of the system. Due to the contradiction between the stroke of the spring and the area of ​​the wind, it is impossible to use only the spring to realize the opening and closing function of the valve for large air volume on the market. Most of the valves in the world are too large in volume and weight or the actuator is relatively large, and the occupied space is too large, which is not conducive to miniaturization design. Moreover, the execution time of such valves is long, which is not conducive to the rapid opening and opening of the ventilation system mouth. In addition, the most important thing is that the valves on the market do not have the function of self-closing after power failure. The solution of the present invention solves the above problems
