Embodiment Construction

[0017] Such as figure 2 As shown, a sewage inlet and exhaust valve includes a valve body 2, a valve cover 1, a floating ball 10, a moving sealing rod 7, an air outlet 3, an air outlet 5 and a hanger 11. The valve cover 1 is fixedly mounted on the upper end of the valve body 2, and the valve cover 1 is provided with an air outlet 3; The lower end of the air outlet is equipped with an annular sealing gasket 6, and a movable sealing rod 7 that can move up and down is installed at the air outlet, and a top plate 8 is fixedly installed in the middle of the moving sealing rod, and the top plate 8 is fixed on the moving sealing rod. Ventilation holes A and B are arranged in sequence from top to bottom under the plate, and the gas in the valve can be discharged from the air outlet through A and B; the lower end of the valve cover and the lower end of the top plate are equipped with an annular gasket 6; The moving seal rod is hollow tubular, and the middle and lower ends are arranged...

Abstract

The invention relates to a sewage inlet / exhaust valve, specifically to an inlet / exhaust valve for sewage containing lots of impurities and gases. The exhaust valve is provided with a gas vent having an enlarged size, which is advantageous for the exhausting of a large quantity of gases in the sewage, and simultaneously capable of preventing blockage; the gas vent is under the protection of a guide rod on a floating ball without contacting with bubbles easily incrusted in the sewage gases, thereby reducing blockage and ensuring long-term operation; besides, the position of the floating ball is in the middle position, so that the diameter of the whole valve body is reduced; and a circular floating ball is employed so that the contact area thereof with the liquid level can be widened and the length of the valve body can be also reduced. The exhaust valve overcomes the defects of impurity blockage and low gas output caused by a small gas outlet of the existing sewage inlet / exhaust valve.

Description

technical field [0001] The invention relates to a sewage intake and exhaust valve, in particular to an intake and exhaust valve for sewage with many impurities and large air volume. Background technique [0002] At present, there are many kinds of exhaust valves, but there are relatively few sewage exhaust valves. Existing sewage composite exhaust valves are usually used, for example, the common ones are as attached figure 1 As shown in the sewage exhaust valve, the valve body contains levers and floating balls and other components, wherein the oval floating ball is close to one side of the valve body, the lever is located on the corresponding side of the floating ball, and the bonnet is located on the side of the valve cover. When the valve body is filled with water, the floating ball falls to the bottom of the valve body under the action of gravity, and a large amount of pressurized gas is quickly discharged from the vent hole. After the air is discharged, the water in t...
