Air directional control valve

Description

The article to which our new design is applied, "air directional control valve", is used by connecting with air pump for controlling air direction, for example, in order to supply compressed air to both directions of back wash and aeration by means of an air pump, in Gappei-shorijohkasou (duplex sewage disposal tank).

This article is designed so as to easily set a time of controlling air direction with keeping air pump connected, by opening a lid of this article, and only pushing buttons.

FIG. 2 is a front view thereof;

FIG. 3 is a rear view thereof;

FIG. 4 is a plane view thereof;

FIG. 5 is a bottom view thereof;

FIG. 9 is a perspective view with a lid open thereof;

FIG. 10 is a front view with a lid open thereof; and,
