Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an upper end of an intermediate joint pipe in which a swirling flow control part that bulges out to the outer peripheral side is provided at the lower end of a pipe pipe having a flowing water reducing wing part on the inner peripheral surface. At the middle of the floor height, it comes into contact with the lower end of the vertical drainage pipe, and a sewage or gray water branch pipe is branched out from the lower end of the intermediate joint pipe, and the lower end of the branched part of the sewage or gray water branch pipe in the intermediate joint pipe is connected to the floor. This relates to a drainage pipe device in a building that is characterized by being connected to the gray water or sewage branch pipe branch at the upper end of a lower floor drainage vertical pipe installed on the floor, and its purpose is to Improved system that slows down the flow of sewage in pipes and lateral branch pipes, reduces internal pressure fluctuations due to flowing sewage, water level fluctuations and water level fluctuation loss values of each equipment pipe trough, etc., and allows drainage and ventilation to be carried out smoothly. The point is that it provides drain pipe counterfeiting at a glance.

The flow rate of wastewater in a vertical pipe reaches its maximum speed at the 4th to 7th point of flow, so it is necessary to efficiently slow down the flow rate before it reaches the maximum speed, depending on the internal pressure fluctuation value and each equipment and pipe. This is effective in reducing trap water level fluctuation values, water level fluctuation loss values, etc.

Accordingly, in the present invention, as described above, an intermediate joint pipe is used, in which a swirling flow control part that bulges out to the outer circumference is attached to the lower part of a tube pipe having a sewage reduction wing part on the inner surface, Its upper and lower ends are connected to the lower end of the drainage pipe as well as the lower sewage and miscellaneous water branch at the middle of the floor height and above the floor, respectively, and the lower sewage and miscellaneous water branch is connected to the lower floor drainage vertical. Since the pipe is connected to the upper end of the pipe, the flowing sewage in the upper drainage vertical pipe is reduced by the sewage reduction blades distributed on the inner peripheral surface of the pipe section of the intermediate joint pipe in the middle part of the pipe before reaching the maximum flow velocity. Slowed down.

Then, the flowing sewage that has been decelerated in its rotation by the flow speed wing section in the pipe section is suppressed from swirling in the swirling flow control section bulging toward the outer periphery, which is installed at the bottom of the pipe section, and
This effectively slows down the flowing sewage and reduces the negative pressure inside the pipe.
Fluctuation values of positive pressure and water level fluctuation values of each equipment and pipe trap,
This can reduce water level fluctuation loss values, etc. Further, as described above, the gray water branch pipe and the wastewater branch pipe are branched out or connected from the intermediate joint pipe and the drainage vertical pipe, respectively, and both branch pipes are separated from each other. By adjusting the relative rotation of the pipes, each of the branch pipes can be piped so as to be oriented in a desired direction, thereby facilitating the piping work.

Also, in manufacturing, etc., planned production is possible, and productivity is good in terms of shape, so material costs are low. Each of the branch pipes also acts as a speed reducer for flowing sewage. Further, in the present invention, since the main body of the drainage vertical pipe passes through the building body, the diameter of the vertical pipe penetrating portion in the vertical body becomes small, and the present invention has many advantages.

The present invention will be described below with reference to the illustrated embodiments.

1 is a drainage vertical pipe in the building, 3 is a gray water joint that protrudes to the outside of the upper end projecting above the same floor 2, and the joint receiving part 3'
A gray water branch pipe 4 is connected via.

Reference numeral 5 designates an intermediate joint pipe, which has a rotating curved surface bulging toward the outer circumference at the lower part of the cylindrical pipe part 6, which has a spiral reduction wing part 7 protruding from its inner circumferential surface or a part of the main body having a helical shape. A swirling flow control section 8 consisting of a body is disposed in a vertical direction, and a joint receiving section 9' is branched out near the lower sewage joint 9 on the outside, to which a sewage branch pipe 10 is connected.

The upper end of the intermediate joint pipe 5 is connected to the lower end of the drainage vertical pipe 1 at the middle of the floor height, and the lower end is connected to the upper end of the lower sewage joint 9 above the floor 2. At this time, by adjusting the relative rotation angle between the gray water joint 3 and the sewage joint 9, each of the branch pipes 4 and 10 can be arranged to extend in a desired direction. Since the drain pipe device according to the present invention is configured as described above, the waste water flowing down the drain vertical pipe 1 enters the cylindrical pipe 6 of the intermediate joint pipe 5,
The speed of the flowing water is reduced by the deceleration wing part 7 which is protruding from the inner circumferential surface or has a part of the main body in the shape of a continuous line. The swing control unit 8 provided therein suppresses the swing and further decelerates the lower part of the sewage joint 9, the gray water joint 3, and the drainage vertical pipe 1.
In this way, the generation of negative pressure and positive pressure within the drain pipe is prevented, and fluctuations in pressure within the pipe, fluctuations in the water level of each device and pipe trap, loss due to water level fluctuation, etc. can be reduced.

Further, each of the branch pipes 4 and 10 also acts as a deceleration section for flowing sewage water. Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
