Abstract

PURPOSE: An air valve for a water supply pipe is provided to reduce the height of a water supply pipe because an opening/closing valve connected between a water supply pipe and an air discharge valve has no flanges. CONSTITUTION: An air valve for a water supply pipe, which is coupled to a flange(2) of a water supply pipe(1) with bolts(3) and nuts(4), comprises an opening/closing valve(100), a connection plate(200), and an air discharge valve(90). The air discharge valve comprises a body(10), a movable valve guide(20), a lid(30), a float ball(40), a movable valve(50), and a cover(60). In the opening/closing valve, a drive lever(141) and a gear box(140) are connected by a shaft. The shaft is inserted to the bottom of the drive lever and fixed with a side pin(142) in order to prevent damage to a disc(120) even under strong manipulation of the drive lever.

Description

Air valve of water supply pipe

The present invention relates to an air valve for a water supply pipe, and more particularly, an open / close valve having a connection portion formed at an outer circumference of a “ㅗ” type water pipe having an upper end formed with a flange, and an open / close valve to fix the open / close valve in position. The connection plate is provided on the upper surface of the, and the air discharge valve is provided on the upper surface of the connection plate for discharging the air of the water supply pipe to the outside, there is a conventional on-off valve to be connected between the water supply pipe and the air drain valve Since the flanges are formed at both ends of the valve, the height of the overall air valve is lowered, so that the water supply pipe does not need to be deeply buried, thereby reducing the construction period and the construction cost. Detachable easily, the lever for rotating the disk in the on-off valve is formed vertically long air The present invention relates to an air valve for a water pipe in which the valve is easy to use.

The maintenance of water and sewage systems will be increasingly important for the improvement of living environment and water quality. In the maintenance of sewerage, the conditions of terrain, land, air, and aerosols are considered, but in a place where the artificial density is relatively low, the pressure feeding method by the pipe which is advantageous in these respects is adopted.

In addition, there is an increasing tendency for the pressure feeding method to be adopted in the sewerage, for example, when the sludge is transferred by the pressure feeding pipe for the concentrated treatment of sludge. Various pipeline systems are also operating in the sewage or sludge treatment plant.

In general, the water supply pipe is provided with a water separator to temporarily control the water flowing into the water supply pipe during maintenance of the water supply pipe, and removes the air introduced into the water supply and the air contained in the water. Air vent valve is installed.

A rapid air valve is used for this purpose, and a rapid air valve can be installed in a water pipe to discharge air in the pipe in a short time, and when drained, external air can be quickly introduced into the pipe to prevent damage to the pipe. .

First of all, the basic function required for the air valve is to exhaust the water during the water supply when the water is filled in the pipeline quickly, and to close the valve after the exhaust in the pipeline to close the water to prevent the leakage of water. It is necessary to perform the above operation automatically to perform the function.

The air valve is installed in the body having a hollow portion, the float is in direct contact with the outlet formed in the upper portion of the body while reciprocating up and down by the constant water level, or to control the discharge of air, or by using a separate auxiliary member The sub-ball may be divided into a method of regulating the discharge of air in a manner in which the auxiliary member pressurizes the auxiliary member to control the outlet.

That is, the above two methods are to release the air inside the outside by opening and closing the outlet opening or the auxiliary member directly connected to the air outlet.

However, in the above method, a gap is generated because the outlet and the sub-port or auxiliary member for opening and closing the opening are difficult to be completely adhered to.

Therefore, if the air discharge structure in which the gap is generated is applied to a relatively small capacity, since the hydraulic pressure acts more than the buoyancy, the internal constant rises to the upper side of the float so that it is discharged to the outside through the gap of the outlet. There is a problem that leaks occur.

The present invention has been made to solve the above problems,

On / off valve formed at the outer periphery of the water pipe of “ㅗ” type water pipe formed with a flange at its upper end, a connecting plate provided on the upper surface of the on / off valve to fix the on / off valve in position, and an upper portion of the connecting plate Since the air bleed valve is installed on the surface and discharges the air of the water pipe to the outside, the flange is formed at both ends of the on-off valve in order to be connected between the water pipe and the air bleed valve in the prior art to eliminate the overall air valve The purpose is to provide an air valve for a water supply pipe, in which the height is lowered so that the water supply pipe does not need to be deeply buried, thereby reducing the construction period and the construction cost.

In addition, it is easy to attach and detach the air bleed valve and the on-off valve by the connecting plate, the lever for rotating the disk in the on-off valve is formed vertically long to provide an air valve for a water pipe for convenient use of the air valve is another object There is this.
