The present invention relates to a water collecting joint for drainage pipes, which prevents the falling water from penetrating into the joint portion of the falling pipe which is interconnected with the dripping pipe by forming the drip guide ring at the bottom side of the dripping pipe of the collecting joint.

When the drainage pipes connected to each other with the conventional downfall pipe are mutually connected, the diameters of the downfall pipe and the downfall drain pipe are different from each other, that is, the interconnection pipe is inserted into the outer circumferential surface of the downfall pipe by the difference in diameter. The method has been used, but due to the difference in diameter, the joint state is not always good, so leakage occurs through the junction or energy loss due to pressurization during joining. The joint connector, which is separately injection-molded, has a joint connector in the shape of a pipe part forming a protrusion having the same height as the thickness of the drain pipe on the inner peripheral surface of the center. The joint condition where the pipe and the drainage pipe are mutually interpolated is good, but the drainage pipe and the drainage pipe It was pointed out that due to the vortices caused by the currents at the edges of the joints and the joints of the connection pipes, the leakage of water leakage between the contact gaps was not solved satisfactorily due to the nature of the fluid and the pressure difference.

In order to solve the above problems, an object of the present invention is to extend the downfall induction wheel on the lower side of the downfall pipe, subtracting the downfall drainage pipe on the outer periphery of the downfall induction wheel and mutually connected with the joint connector, which is a separate molded part. It is to provide a water collecting joint for drainage pipes to secure the joint state and to reduce the energy due to the pressurization to prevent leakage at the joint.

Hereinafter, described in detail with respect to the technical configuration and operation of the present invention.

The present design is composed of a downfall pipe 20, a downfall drainage pipe 40 and the junction connecting pipe 60, the downfall pipe 20 is a downfall pipe 20, downfall support pipe 22, stepped (23) ) And the downfall induction wheel 24 is divided into the downfall pipe 21 is a drainage connection pipe formed integrally or in combination with the upper injection pipe 10 and the transverse connection pipe 11, and the downfall support pipe 22. And downfall induction wheel 24 has a shape.

And the downfall support tube 22 has a step 23 of inward or wedge-shaped right angles of the inner periphery and the outer periphery having a uniform, homogeneous surface, and the inner periphery extends to have the induction wheel 24. .

The lower end 25 of the downfall induction wheel 24 has a cross section or an inclined surface to reduce a change in flow velocity or to prevent vortex, and has a thickness less than that of the downfall induction wheel 24, while the inner periphery is the same. The vertical surface is maintained, and the outer periphery of the drip guide wheel 24 has a stepped shape that facilitates engagement at the step 23.

The drainage drainage pipe part 40 is composed of the coupling support pipe 41 and the upper end 42, the thickness of the coupling support pipe 41 is the drainage drainage pipe part 40 on the outer periphery of the downfall induction wheel 24 It has a thickness to maintain the same outer circumferential surface and the outer circumferential surface of the downfall support tube 22 during the subtraction, the upper edge 42 is to have a right angle (or wedge) shape.

Bonding connecting portion 60 is to allow the connecting pipe 61 to perform the local area, to form a wheel wheel 62 having a suitable height and width in the inner central portion, and the inner sealing end of the joint sealing ring (soft rubber material) ( A groove for inserting 63) is formed. The joint sealing ring 63 is to maintain the more tightly coupled state and leakage prevention when the fall pipe 20, the fall drain pipe 50 and the joint connecting pipe portion (60) are mutually coupled.

Junction connecting pipe portion 60 has an inner diameter that can be inserted in close contact with the outer diameter of the drop support pipe 22 and the coupling support pipe (41).

In addition, the downcoming flow ring 24 of the sump joint for drainage pipes is also used for a horizontal pipe such as a transverse support connecting pipe 11 as well as a downfalling pipe 20.

Hereinafter, the operation and effects of the present invention will be described in detail.

The present invention inserts the junction connecting portion 60 on the outer periphery of the downfall support tube 22 of the downfall pipe 20, the downfall drainage pipe 40 and the outer periphery of the downfall induction ring 24 and the joining pipe (60). The fluid is allowed to fall inside the downcomer pipe part 20 by making a close contact between the inner circumferences of the inner side) and making a tight close contact between the step 23 of the downfall support tube 22 and the protrusion 62 and the upper end 42. Due to the flat surface shape of the falling edge induction wheel 24 and the lower edge 25 of the falling induction wheel 24, the turbulence can be minimized and the vortex can be prevented to prevent leakage between the joints. In view of the fact that the bonding force can be increased, the practical value is high.

Claims (1)
