That is, the present invention prevents foreign matter from directly entering the inside of the valve body 513 to block the valve body 513 by providing the U-shaped air pipe 516 and storing the muddy water, the fine sand, and other foreign matter at the bottom of the U-shaped air pipe 516.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
