a ventilated valve

Abstract

The invention relates to a ventilated valve which is used in a power distribution cabinet. The ventilated valve is characterized in that a vertical connection piece bent by 90 degrees is arranged at the end of a dummy plate, a dodge gate which can perform ventilation under normal status and quickly close in an accident is arranged on the vertical connection piece, the dodge gate is composed of a cuboid space formed by connecting steel sheets and an oscillating board hinged in the cuboid space, and vent holes are formed in two adjacent side faces of the cuboid space. The ventilated valve has the advantages that when the ventilated valve is under gravitation action usually, the oscillating board is under an open state, two small chambers located above and below the oscillating board achieve ventilation convection so as to ventilate inner electric devices, the inner electric devices are prevented from conducting due to moist, and when the accident happens, the rotatable side of the oscillating board under strong airflow action is attached to the inner wall of the cuboid steel, the vent holes are closed, and then accident spread is avoided.

Description

technical field [0001] The invention relates to a ventilating valve, which is applied to the partitions of the upper and lower chambers inside the power distribution cabinet for ventilation and heat dissipation. Background technique [0002] The internal space of the power distribution room of the existing switchgear is divided into two small rooms by the partition board: the mother room and the cable room. There is no ventilation between the two small rooms and there is no way to dissipate heat. It is easy to cause accidents caused by electrical moisture and conduction. Ventilation window, when an accident occurs in one of the two small rooms, it will be passed to the other small room immediately, which will cause a relatively destructive safety accident. Can you design a ventilated valve that can be automatically closed in dangerous situations? , has become a key issue in reducing safety accidents. Contents of the invention [0003] The object of the present invention i...
