While flowing through flowing water to flow through the main pipe 110 to the meter 90, the foreign substances contained in the flowing water are collected to prevent interference or damage to the meter 90 due to the foreign matter. [At this time, when the distance from the intermediate valve 30 to the meter 90 is long, the discharge pipe 20 can be provided with a long length as in the prior art document or interposed with the main pipe 110 of the present invention therebetween. Of course, as shown in FIGS. 3A to 3C, the main pipe 110 may be the discharge pipe 20, and both ends of the main pipe 110 may be screwed with a nut or a flange. .

Particularly, when the filter 130 is directly provided in the main pipe 110, the flow of flowing water may be impeded by the amount of deposit of foreign matter, but in the present invention, the branch pipe 120 is branched from the main pipe 110. By providing the filter 130, even if the amount of deposit of foreign matter increases, the flow of the flowing water to the main tube 110 is not disturbed, but the protection of the filter 130 by the branch tube 120 is also maximized. To make it possible.

Preferably, the branch pipe 120 is branched in the diagonal direction with respect to the flow direction of the flowing water from the main pipe 110 so that the foreign substances contained in the flowing water can be collected in the filter 130 in the diagonal direction with the flow of the flowing water. do.

Specifically, the filter 130 is composed of an upper opening 131, a lower opening 132, and a circumferential network 133 to allow foreign matter to be accommodated through the upper opening 131, while the cap 140 contacts the lower opening 132. ) To collect and confine foreign substances along with the circumferential network 133.

More preferably, the upper end 131 is provided with an inner support jaw 150 stepped in a diagonal direction from the main tube 110 to the branch tube 120 so that the upper end of the circumferential network 133 is supported in contact with each other. The circumferential network 133 in which the lower opening 132 is sealed by the cap 140 while receiving foreign substances contained in the flowing water while allowing the entire amount of flowing water flowing from the intermediate valve 30 to flow into the meter 90 Try to be captured in.

The inner opening jaw 150 is stepped in a diagonal direction from the main pipe 110 to the branch pipe 120 so that the upper end of the circumferential network 133 abuts in the diagonal direction so that the upper opening 131 is an intermediate valve ( 30) while maintaining the open state toward the water and foreign substances can be accommodated, while the circumferential network 133 maintains the closed state toward the meter 90 to ensure the passage of the flowing water and realize the collection of foreign substances, thus preventing resistance. It enables the flow of water and the thorough collection of foreign substances.

That is, the filter 130 is opened to the intermediate valve 30 through the upper opening 131 while being closed toward the meter 90 through the circumferential network 133.

4A and 4B are exploded perspective views of the reverse flow prevention valve V applied to the water piping device according to the present invention, as viewed from the front and rear, respectively.

The water piping device according to the present invention is inserted into the main pipe 110 as shown in FIGS. 3A to 4B to ensure flow (forward flow) to the meter 90 of flowing water while flowing to the intermediate valve 30 of flowing water It includes a backflow prevention valve (V) to regulate (reverse flow).

When removing the foreign matter accumulated in the filter 130, when the intermediate valve 30 is closed and the cap 140 is removed, the reverse flow phenomenon of the flowing water from the meter 90 is prevented as the backflow prevention valve V to prevent the meter 90. This is to prevent contamination of the surroundings and remove foreign substances easily.

Preferably, the main pipe 110 has an entry prevention jaw 112 in the inner passage 111, and the backflow prevention valve V is provided with an outside o-ring 41 on the outside and a departure prevention jaw 42 on the inside. While being supported by the entry prevention jaw 112, the inside of the passage 111 is forcibly fitted into the protection tube 40, and has an outer O-ring 51 with an inner shielding hole 52 and an assembly hole 53 to provide a departure prevention jaw 42 While being supported by ), it is supported by an assembly tube 50 that is forcibly fitted into the protection tube 40, and a side rib 64 having side holes 63 while having a central hole 61 and a circumferential support groove 62, At the same time, it is provided with an outer O-ring 65, the support tube 60 forcibly fitted into the assembly hole 53, the spring 70 supported by the circumferential support groove 62, and the center hole while passing through the spring 70 ( 61) is fitted and elastically protruded outward on the upper end of the opening/closing shaft 80 to open and close to open the inner blocking hole 52 at the time of rectification so that the flowing water flows through the side holes 63 in the forward direction. On the other hand, it includes an opening/closing protrusion 81 that elastically closes the inner shielding hole 52 at the time of reverse flow to block reverse flow of flowing water.

The assembly tube 50 and the support tube 60 can be firmly protected by the protection tube 40 in an assembled state, thereby maximizing the fixing force between each other and having a spring 70 and an opening/closing protrusion 81 at the same time.
