Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a pipe joint for a buried drainage pipe, and relates to a structure to which a cleaning port pipe can be connected.

(Prior technology) Generally, when connecting a drainage branch pipe from a kitchen, bathroom, toilet, etc. to the main drainage pipe, if there is no space in the residential area to install an invert pipe at the confluence part where it connects to the main drainage pipe, the drainage branch pipe The construction method used is to connect the pipe to the drainage main using a 90° Y-joint. In this case, connect a branch joint such as a Y joint with a 90° bend to the upstream side of the confluence of the main drainage pipe and the branch pipe to enable inspection and cleaning, and stand on the ground at the branch socket of this branch joint. A piping method is used that connects the ascending cleaning port pipe.

(Problems to be solved by the invention) The conventional piping method described above requires a branch joint to branch and connect the cleaning port pipe and a short pipe to connect this branch joint, making the piping complicated and reducing the workability of piping. Evil has its drawbacks.

The present invention was developed in view of the above-mentioned drawbacks, and the cleaning port pipes that connect the cleaning port pipes to the upper and lower surfaces of the joint body that connects the confluence of the main drain pipe and the drain branch pipe are connected to each other so that cleaning can be easily performed. A connection that protrudes from the bottom side of the joint body, in which the drainage branch pipe can be connected in either the left or right direction by forming the joint body in the opposite direction and reversing the joint body depending on the connection method of the drainage branch pipe. To provide a pipe joint for an embedded drain pipe in which a joint body does not become unstable due to a mouth part.

[Structure of the invention] (Means for solving the problem) The present invention has connection ports for connecting cleaning port pipes protruding from the upper and lower surfaces of each socket in a direction perpendicular to each socket. It is equipped with a joint body and a lid body that is selectively fitted to either one of the connection ports of the joint body, and the connection port that is on the lower side depending on the connection direction of the drainage branch pipe is fitted with the lid body. In a device that is closed and can be cleaned by connecting a cleaning port pipe to the upper connection port, the joint body has an upper and lower surface from which the connection port protrudes, respectively, at approximately the same height as the connection port. It has a protruding support leg.

(Function) In the pipe joint of the buried drainage pipe of the present invention, the joint body is arranged in accordance with the connection direction of the drainage branch pipe, and the lid body is fitted by aligning it with the connection opening on the lower side. and seal it liquid-tightly. In this state, the bottom surface of the protrusion of the lid body becomes a surface continuous with the inner circumferential surface of the joint body. Then, a drainage main pipe is connected to the sockets at both ends on the main pipe side of the joint body, and a drainage branch pipe is connected to the sockets on the branch side.

Further, a cleaning port pipe is connected to the connection port on the upper side of the joint body and raised above the ground, and a cleaning port cover is removably fitted into the upper end opening of the cleaning port pipe.

The fluid flowing inside the joint body has a closed lower connection port that is continuous with the inner circumferential surface of the joint body through the protrusion of the lid body, so that no recesses or protrusions are formed, and dirt is removed. It flows smoothly without getting caught.

In addition, when inspecting or cleaning, open the cleaning mouth lid and perform cleaning from the cleaning mouth tube.

(Example) Next, the configuration of an example of the present invention will be described with reference to the drawings.

Reference numeral 10 denotes a 90° large-bend Y joint body molded from vinyl chloride resin, and there are internally facing upper and lower sides perpendicular to both end sockets 11 and 12 on the main pipe side and socket 13 on the branch side. Connection openings 14 and 15 for connecting cleaning port pipes are formed to communicate with each other.

Furthermore, on the upper and lower surfaces of the joint body 10 from which the connection ports 14, 15 are protruded, support legs 16, 17 having a substantially rectangular frame shape are integrally provided at the positions of the sockets 11, 12, 13 at substantially the same height as the connection ports 14, 15.

Reference numeral 18 denotes a lid for selectively closing either one of the connection ports 14, 15, and the lid 18 includes a flange-like portion 20 that engages with the upper opening edge 19 of the connection ports 14, 15. , and a protrusion 21 having a length that is fitted to the inner ends of the connection ports 14 and 15,
The shape of the bottom surface 22 of this protrusion 21 is continuous with the inner circumferential surface 23 of the joint body 10, and the shape of the bottom surface 22 of this protrusion 21 is continuous with the inner circumferential surface 23 of the joint body 10, and the shape of the bottom surface 22 is continuous with the inner peripheral surface 23 of the joint body 10. No recesses or protrusions are formed therein.

Further, a positioning portion (not shown) is formed in the brim portion 20 of the lid body 18 .

Next, the piping method of the pipe joint of this embodiment will be explained with reference to FIG.

The joint body 10 corresponds to the connection direction of the drainage branch pipe 24.
is disposed, aligned with the lower connection port 15, and fitted with the lid 18 to close it liquid-tightly. In this state, the bottom surface 22 of the protrusion 21 of the lid body 18 becomes a surface continuous with the inner circumferential surface 23 of the joint body 10.

Then, as shown in FIG. 2, connect the drain main pipe 25 to both end sockets 11 and 12 on the main pipe side of the joint body 10,
A drainage branch pipe 24 is connected to the outlet 13 on the branch side.

Further, a cleaning port pipe 26 is connected to the connection port 14 on the upper side of the joint body 10 and raised above the ground, and a cleaning port cover 27 is detachably fitted to the upper end of the cleaning port pipe 26.

Next, the operation of this embodiment will be explained.

The fluid flowing through the joint body 10 is connected to the joint body 10 by the closed lower connection port 15 at the protrusion 21 of the lid body 18.
It is a continuous surface to the inner circumferential surface 23 of the recessed part,
No protrusions are formed, so dirt can flow smoothly without getting caught.

Inspection and cleaning are performed through the cleaning port pipe 26 by opening the cleaning port 27.

Furthermore, a connection port portion 15 is provided protruding from the lower surface of the joint body 10, and support legs 17 are connected to each socket 11, 1.
Since the parts 2 and 13 are protruded, the joint body 10 can be buried stably.

Further, in the above embodiment, the joint body 10 has a large bend Y of 90°.
Although a joint body was used, a 90° Y joint body, a 45° Y joint body, a 90° large bend elbow, etc. can also be used.

[Effects of the invention] According to the invention, the connection ports for connecting the cleaning port pipes are provided protrudingly on both sides of the joint body in the direction perpendicular to the socket, so that it is possible to Accordingly, by turning the connection port of one of the joint bodies downward and closing it with the lid body, it is possible to connect the drain branch pipe to the joint body of the same shape in either the left or right direction.
The versatility of the joint body is increased, only one mold is required, and it can be manufactured at low cost.Furthermore, the joint body has support legs formed on the upper and lower surfaces where the connection opening is formed, so that the lower surface side of the joint body and Even if the connection port protrudes from a different surface, it can be stably buried by the support legs, and the cleaning port pipe can also be stably raised above the ground.
