After the water flows out, the sealing gasket can be closed again by the elasticity of the material. The tail plug can prevent the high-pressure pump water from directly flushing the sealing gasket and simultaneously prevent the sludge from directly flushing the sealing gasket, thereby ensuring that external water, dust, moisture, reptiles and the like invade the interior of the electrical equipment.

Description

One-way valve type automatic drainage device

Technical Field

The utility model relates to an electrical equipment's drainage device, in particular to automatic drainage device of check valve formula.

Background

The drainage device is mainly used in the scene of water inlet of the electric device caused by condensed water or improper protection due to temperature difference. Drainage among the prior art, its case generally adopt dull and stereotyped case or spherical case, and the spring in the valve body is pressed the case on the apopore, and the shortcoming of this kind of structure is that the spring part is indispensable, and the spring is fixed in the technology trouble of valve body, and the spring uses for a long time can cause the elastic coefficient to reduce, influences the result of use.

Disclosure of Invention

The invention aims to overcome the defects of the background technology and provide a drainage device which has simple structure, convenient installation and long service life.

The technical scheme of the utility model is that: the utility model provides an automatic drainage device of check valve formula, includes drainage device's casing, is equipped with drainage channel in the inner chamber of casing, and the top of casing is drainage channel's water inlet, and the bottom of casing is drainage channel's outlet, drainage port department is equipped with the tail stopper, is equipped with elastic separation plate and sealed pad between tail stopper and water inlet, sealed pad laminating in the elastic separation plate below, elastic separation plate fixes on the casing inner chamber.

The utility model has the advantages that: the automatic drainage device is simple in structure and low in manufacturing process requirement, is a one-way valve type automatic drainage device, and when condensate water of electrical equipment is discharged, due to the factors of gravity and water pressure, the non-fixed end of the elastic partition plate is pressed downwards to form a drainage gap, and water is discharged along a drainage channel through the drainage gap. When the electrical equipment installation of work on the surface of water the utility model discloses the time, the surface of water and sealed pad and the contact of resilient barrier, the buoyancy of water can make sealed pad paste on resilient barrier and seal the apopore of top completely, can prevent that outside water from passing through inside drainage device gets into electrical equipment. The utility model discloses a sealed pad and elastic separation board still play dustproof effect, inside outside granule also can't get into electrical equipment through drainage device.

Drawings

FIG. 1 is an internal cross-sectional view of the present invention;

fig. 2 is an external plan view of the present invention;

FIG. 3 is a schematic structural view of the present invention installed on an electrical device;

wherein: 1. the automatic drainage device comprises a one-way valve type automatic drainage device, 2, a shell, 3, a drainage channel, 4, a water inlet, 5, a water outlet, 6, a tail plug, 7, an elastic partition plate, 8, a sealing gasket, 9 and electrical equipment.

Detailed Description

The one-way valve type automatic drainage device (1) as shown in fig. 1 and 2 comprises a shell (2), a drainage channel (3) is arranged in an inner cavity of the shell, a water inlet (4) is formed in the upper end of the drainage channel (3), a water outlet (5) is formed in the lower end of the drainage channel, and an elastic partition plate (7) is arranged below the water inlet.

The elastic partition board is preferably made of a spherical brass particle sintered molding part, and the outer edge of the elastic partition board is in contact with the inner edge of the inner cavity of the shell. And a sealing gasket (8) is laid at the bottom of the elastic partition plate, and the sealing gasket is preferably a rubber gasket.

A tail plug (6) is arranged at the water outlet, and the tail plug is preferably made of plastic. The plastic tail plug is mounted to the interior of the housing by a cold pressing process. The tail plug is provided with a fixed support which is fixed on the inner cavity of the shell by compressing one end of the rubber pad and the elastic clapboard. Thus, the elastic partition and the gasket are partially fixed and partially non-fixed in contact with each other.

The tail plug (6) can protect the sealing gasket (8) from being touched from the water drainage port.

The shell (2) is integrally circular or hexagonal, and different water outlet holes are formed in the shell according to different water discharge amounts. The upper part of the shell (2) is provided with an external thread to be connected to the electrical equipment to be used.

As shown in figure 3, the check valve type automatic drainage device (1) is only arranged on the inner wall of the electrical equipment (9) through a tool, and the integral integrity of the device used by a user is ensured.

When condensed water or other parts formed in the electric device enter water, the water can automatically open the elastic partition plate (7) and the sealing gasket (8) under the action of gravity and flow to the outside along the drainage channel (3). After the water flows out, the elastic partition plate (7) and the sealing gasket (8) can be closed again by the elasticity of the material. The tail plug (6) can prevent the high-pressure pump water from directly flushing the sealing gasket (8) and simultaneously prevent the sludge from directly flushing the sealing gasket (8), thereby ensuring that external water, dust, moisture, reptiles and the like invade the interior of the electrical equipment (9).
