The present invention relates to a tubing washing and inspection hole in which a fire hose connecting valve and an air valve are installed, and more specifically, to minimize the occurrence of water pressure caused by the air introduced into the water and sewage pipes. As well as securing the durable durability of water and sewage pipes, in particular, it is possible to supply fire extinguishing water quickly by connecting fire hoses to extinguish fire, thereby improving the efficiency of pipe washing and inspection openings. Fire hose connecting valve and air septic pipe cleaning and inspection.

In general, the pipe washing and inspection opening (1) is installed between the water and sewage pipes (A) to discharge foreign substances and sludge accumulated in the pipes so that the fluid flow in the pipes can be smoothly flowed ( In order to increase the water efficiency, such a conventional pipe washing and inspection port (1) configuration is as shown in Figure 1, the injection pipe 10 connected between the water supply and sewage pipe (A), and the input It is formed in the vertical direction on the upper portion of the tubular body 10 consists of a pig inlet 11 for injecting a pig for removing foreign matter and sludge, and a cover 20 coupled to the upper portion of the pig inlet 11 At this time, the poly pig (Polly-pig) through the pig inlet 11 to clean the foreign matter inside the water, sewage pipe and discharge the high pressure water at a constant pressure from the poly pig (not shown) ) Inside the water and sewer pipes As it passes through the high-speed rotation, foreign matter or sludge on the inner wall of the water and sewage pipes is efficiently removed.

However, in the conventional pipe washing and inspection opening (1), air is inevitably introduced into the inside of the pipe during the cleaning operation of foreign substances and sludge, thereby reducing the cross-sectional area of the water flow in the pipe, thereby decreasing the water supply efficiency of the fluid. In addition, since the movement of the poly pig is not smooth, it will have a closed end of the washing efficiency.

In addition, the density difference is generated between the fluid and the air transported by the air introduced into the pipe, so that severe noise and water pressure is generated eventually, the upper and the sewage pipe is deformed or damaged to provide a cause of leakage Got

In addition, the conventional pipe washing and inspection opening (1) is not used for other purposes other than the role for washing and inspection of water and sewage pipes, and as a result, limitations in the use efficiency and working range of the conventional pipe washing and inspection opening (1) occur. There is a problem that occurs.

The present invention has been devised to solve the problems of the conventional pipe washing and inspection port, by connecting the air stools for efficiently discharging the air introduced into the pipe and the fire hoses of various standards in the event of a fire to smooth the firefighters It is to provide a fire hose connecting valve having a fire hose connecting valve for supplying, and a pipe washing and inspection hole provided with an air valve.

When described in more detail by the accompanying drawings the technical configuration for achieving the object of the present invention as described above are as follows.

Figure 2 is a perspective view for showing the pipe washing and inspection holes attached to the fire hose connection valve and the air valve of the present invention,

Invented fire hose connecting valve and the air pipe installed in the pipe washing and inspection port 100 is connected to the upper and the sewer pipe (A), and formed in the vertical direction on the upper portion of the input pipe and the foreign matter and sludge In the well-known pipe cleaning and inspection opening consisting of a pig inlet for injecting the pig for removal and a cover coupled to the upper portion of the pig inlet,

The fire hose connecting valve 130 and the air valve 140 is formed on the upper portion of the cover 120.

In the present invention, the fire hose connection valve 130 is configured to quickly extinguish a fire by connecting a fire hose used in an emergency fire, wherein the fire hose connection valve 130 has various specifications. It was formed to be combined with the fire hose having, for this purpose it is preferable to form so as to be able to connect with the fire hose having a 65mm and 40mm standard.

Therefore, the fire hose connecting valve 130 is to be able to use quickly connected regardless of the location and location of the fire truck is not accessible when the fire occurs, thereby enabling the initial suppression of the fire.

On the other hand, the air valve 140 to discharge the air generated during the cleaning and inspection work in the water, sewage pipe (A) to the outside, this is due to the noise and water pressure caused by the density difference between the air and the fluid It will be possible to secure the durability by minimizing the occurrence of.

In addition, a pressure gauge may be formed at the upper end of the cover 120 so that an operator can easily check the pressure inside the pipe.

As such, the pipe washing and inspection opening 100 in which the fire hose connecting valve and the air valve are provided is a structure that does not require the modification and modification of the conventional pipe cleaning and inspection opening 1, thereby minimizing the burden of economic cost of the user. Not only can it be done, in particular, it is possible to increase the range and use efficiency of the pipe washing and inspection openings.

Although the embodiments of the present invention have been described in detail as described above, the scope of the present invention is not limited thereto, and it is natural that the scope of the present invention is included to those which are substantially equivalent to the embodiments of the present invention. something to do.

As such, the present invention can discharge the air generated during the washing and inspection of the pipe to the outside, which induces the smooth movement of the poly pig, thereby improving the washing efficiency of the water and sewage pipes, as well as the air and the fluid. Due to the difference in density, noise and water pressure can be minimized, thereby ensuring durability.

In addition, the present invention has the advantage that it can quickly suppress the fire by connecting the fire hose of various standards used in the emergency fire to suppress the fire.

In particular, the present invention is a very useful design that can maximize the efficiency and range of use of the device because it can supply pipe cleaning and inspection or fire water.
