To provide a pipe washing device having an air valve and a water supply valve composed of a cover, the present invention can be discharged to the outside air generated during the pipe washing operation to smooth the movement of the poly pigs and thereby The efficiency of the air can be expected and the density of air and fluid can be eliminated by removing the air introduced into the pipe. The noise and vibration caused by the difference can be prevented in advance, and the water supply valve can quickly supply water to the fire engine in case of an emergency fire, which can be very helpful for the early evolution of fire. will be.

Description

A pipe washing device having an air valve and a water supply valve

The present invention relates to a pipe washing apparatus, and in particular, by forming an air valve for discharging the air introduced into the tube to the outside to smooth the flow of fluid during the pipe washing work to improve the cleaning efficiency, and also in the event of fire The present invention relates to a pipe washing device having an air valve and a water supply valve to increase the useful value of the pipe washing device by providing a water supply valve to supply water.

In general, the pipe washing apparatus 1 is connected to the water and sewage pipe A to discharge foreign substances or sludge accumulated in the pipe, and is formed on the top of the input pipe 10 as shown in FIG. 1. It consists of a pig inlet 11 and a cover 20 coupled to the upper surface of the pig inlet, and after injection of the poly pig (POLLY-PIG) through the pig inlet 11 to spray high-pressure water at a constant pressure When the poly pig is passing through the inside of the pipe at high speed to remove foreign substances or sludge on the inner wall of the tube.

However, during the cleaning operation, air is inevitably introduced into the pipe, which reduces the water supply cross-sectional area of the pipe, which lowers the efficiency of water supply. You will have this falling edge. In addition, the density difference is generated between the fluid and the air transported by the air introduced into the tube, thereby causing severe noise and vibration, so that the tube is deformed or broken and has a closed end that may cause leakage.

In addition, the conventional pipe washing apparatus 1 is not to be used for any other purpose than the addition of poly pigs for washing the pipe is a very inefficient device in view of the operation and installation costs.

The present invention has been devised to solve the closed end of the conventional tube washing apparatus, a tube washing apparatus having an air valve for discharging the air introduced into the tube, and a water supply valve for supplying water in case of fire. By forming, it keeps vacuum state by releasing air in the pipe during pipe washing, so it can increase the efficiency of washing by smoothing the flow of fluid, and also increases the useful value of pipe washing equipment by supplying water in case of fire. It is to provide a pipe washing apparatus having an air valve and a water supply valve.

Referring to the configuration of the subject innovation in detail as follows.

Figure 2 relates to an exploded perspective view to show the configuration of the present invention, the pipe cleaning device 100 having an air valve and the water supply valve of the present invention is coupled to the water supply and sewage pipe (A) and pigs for injecting the poly pig In the well-known pipe cleaning device consisting of an inlet tube formed in the upper portion, and a cover coupled to the upper portion of the pig inlet, the extension pipe 110 is coupled to the upper end of the pig inlet and the flange is formed at both ends, and The cover 120 is flange-coupled to the upper end of the extension tube and has a water valve 130 for discharging the air in the tube to the outside and a water supply valve 140 for supplying the fluid in the tube to the fire engine in case of fire.

The extension pipe 110 is to increase the height of the pig inlet of the pipe washing apparatus 100, which is to facilitate the operation of the air valve 130 and the water supply valve 140 formed on the top of the extension pipe. will be.

That is, the tube washing apparatus 100 is usually installed in a manhole, and the conventional tube washing apparatus does not have an air valve 130 and a water supply valve 140, so that there is no need for manipulation, so the height must be high. Although it was not necessary, the present invention washing machine 100 is formed by the air valve 130 and the water supply valve 140, the position of the cover 120 should be formed higher than the pig inlet for convenience of operation Extension pipe 110 having the same function as to increase the height of the pig inlet is required.

The extension pipe 110 may be made of a circle (단면) is easy to produce a cross-sectional shape, or may be made of a rectangular shape to facilitate the introduction of a rectangular poly pig, as shown in FIG.

At this time, the shape of the cover should be the same as the shape of the upper end of the extension pipe 110 in consideration of the ease of coupling.

The upper end of the cover 120 is formed with a pressure gauge 150 configured to allow the operator to easily check the constant pressure inside the pipe, the handle 121 is formed on both sides to facilitate the opening and closing of the cover (開 閉) is formed. Lose.

Thus, the present invention tub washing device 100 is manufactured in a structure that can be easily mounted as it is, without the need for special transformation and modification when combined with the conventional pipe washing device (1), it is possible to utilize the existing facilities as it is, It is possible to increase the utilization value of the tube washing device significantly without incurring a large cost.

As such, the present invention can discharge the air generated during the pipe washing operation to the outside, thereby smoothing the movement of the poly pig, and thus improving the washing efficiency, and also removing the air introduced into the pipe. It is possible to prevent noise and vibration caused by the density difference between air and fluid in advance, and also to supply fire engine water to fire engine quickly in case of emergency fire by water supply valve, which is very helpful for early fire extinguishing. It is a very useful design.
