Abstract

The invention relates to an explosion-proof breathing drain valve. A gap exists between a valve core and the inner wall of a valve boy, and the valve core can slide in the valve body so that the valve core vibrates up and down in an electrical operating process, thereby greatly increasing the speeds of draining water and oil; and the top end of the valve core and a seeper hole arranged thereon are inclined planes matched with a plurality of spiral water channels to form stepped water drainage, and when one spiral water channel is blocked, water can be discharged out from the other spiral water channels, thereby greatly prolonging the service life of water drainage.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a drain valve used on electrical equipment and having explosion-proof, dust-proof and water-ingress-proof functions. Background technique [0002] The condensed water produced in the sealed cavity inside the electrical equipment or the external water entering the equipment after the seal failure of other parts needs to be discharged through the drain valve. If the motor works in a humid working environment, the drain valve should also be able to limit the external water. If the motor is used in a working environment with explosion-proof requirements, the drain valve must also be able to discharge the condensed gas that may cause an explosion hazard in the sealed explosion-proof electrical equipment cavity to a certain pressure from the drain valve. [0003] The patent application number is: 200910029343.X discloses an explosion-proof water outlet valve in the technical solution, i...
