Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses drain pipe ventilation cap.

Referring to fig. 1 and 2, the vent cap of the drain pipe comprises a cap body 1, a filtering piece 2 and a pipe joint 3 which are arranged from top to bottom in sequence, wherein the cap body 1, the filtering piece 2 and the pipe joint 3 are fixedly connected through threads.

The upper half part of the cap body 1 is in a round table shape, the lower half part of the cap body is in a cylindrical shape, and 6 air holes 11 are formed in the side surface of the round table shape of the cap body 1. The pipe joint 3 is fixedly connected with the vent pipe through threads. The breather pipe is communicated with the drain pipe. The drain pipe can be communicated with the atmosphere, so that the drainage in the drain pipe is smoother, fresh air is supplemented into the drain pipe, the corrosion of the drain pipe is reduced, and the service life is prolonged.

Referring to fig. 2 and 3, in order to prevent impurities from entering the drain pipe through the vent pipe to affect the water quality, the cap body 1 further comprises a screen 12 and a rain shield 13. The screen 12 is fixed in the air holes 11 by gluing, and the rain shield 13 is fixed above the air holes 11 on the cap body 1 by welding to cover the air holes 11.

The screen 12 can effectively prevent sundries such as insects, sand stones and the like from entering the drain pipe to influence the water quality, and the rain baffle 13 can effectively prevent raindrops and the like from falling on the cap body 1 from entering the drain pipe to influence the water quality.

In order to prevent harmful gas emitted from the drain pipe from diffusing into the air, the cap body 1 further comprises an upper sieve plate 14, and the upper sieve plate 14 is fixed in the cap body 1 through welding. The filter element 2 comprises a filter sleeve 21, a lower screen plate 22 and a filter material 23. The lower sieve plate 22 is fixed in the filter sleeve 21 through welding, the filter material 23 is positioned on the lower sieve plate 22, and the filter sleeve 21 is fixedly connected with the cap body 1 through threads. When the filtering sleeve 21 is fixedly connected with the cap body 1, the upper sieve plate 14 and the lower sieve plate 22 form a cavity, and the filtering material 23 fills the cavity between the upper sieve plate 14 and the lower sieve plate 22. The filter material 23 may be activated carbon.

The gas in the vent pipe is exhausted into the air or enters the vent pipe to be filtered by the filter material 23, so that the harmful gas in the drain pipe does not pollute the air environment, and the gas in the air does not influence the water quality in the drain pipe.

In order to enable the ventilation cap to accommodate different sizes of ventilation tubes, the pipe connector 3 is provided in several numbers. The outer surface of the pipe joint 3 is also engraved with a size mark 31.

The plurality of arranged pipe joints 3 can be matched with breather pipes with different sizes, and the size mark 31 is convenient for operators to install and use.

In order to make the ventilation cap more durable and corrosion-resistant, the cap body 1, the filtering sleeve 21, the pipe joint 3, the upper sieve plate 14 and the lower sieve plate 22 are all made of stainless steel materials.

The implementation principle of the drain pipe ventilation cap in the embodiment of the application is as follows: the pipe joint 3 is screwed on the breather pipe, the filter sleeve 21 is screwed on the pipe joint 3, the filter material 23 is put on the lower sieve plate 22, and then the cap body 1 is screwed on the filter element 2. The drain pipe is communicated with the atmosphere, so that the air pressure in the drain pipe is balanced, and the drainage is smoother. The screen 12 and the rain baffle 13 on the cap body 1 prevent sundries from entering the drain pipe to pollute the water quality. The filter material 23 of the filter member 2 prevents the harmful gas in the drain pipe from directly diffusing into the air to pollute the air, and also prevents the gas in the air from directly entering the drain pipe to pollute the water. The whole ventilation cap is safer and more environment-friendly.
