Detailed Description

For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1-4, the invention discloses a special rotational flow assembly for building drainage, which comprises a first water inlet pipe 1 and a second water inlet pipe 2 connected with the side wall of the first water inlet pipe 1 and communicated with the inside, wherein the inner edge of the second water inlet pipe 2 is tangent to the inner edge of the first water inlet pipe 1, and the communicated part of the second water inlet pipe 2 and the first water inlet pipe 1 is a pipe wall cavity 3 with a large volume.

From this, when sewage entered first inlet tube 1 along second inlet tube 2, the setting of pipe wall cavity 3 can increase the radius of curvature of sewage adherence whirl. When sewage discharge capacity is great, can effectively reduce the discharge rate of sewage, ensure that sewage can the wall whirl, avoid the water stopper to form, reduce the production of drainage noise simultaneously.

In this embodiment, the first inlet pipe 1 and the second inlet pipe 2 are integrally injection molded; the first water inlet pipe 1 and the second water inlet pipe 2 form an included angle of 90 degrees.

In addition, the first water inlet pipe 1 is of a funnel-shaped structure with a wide upper part and a narrow lower part. Therefore, when sewage flows in the first water inlet pipe 1 in a wall-attached rotational mode, the rotational flow radius of the sewage is gradually reduced, and the discharge rate of the sewage is improved.

Referring to fig. 1-3, a pipe cover 6 is disposed at the upper end of the first water inlet pipe 1, a pipe connector 7 is disposed on the pipe cover 6, and the pipe connector 7 is communicated with the first water inlet pipe 1. The lower end of the first water inlet pipe 1 is provided with a first vertical pipe 8, and the first vertical pipe 8 is also communicated with the first water inlet pipe 1.

In this embodiment, the pipe joint 7 is communicated with the upper layer main drainage pipeline and is used for receiving sewage drained from the upper layer; the second water inlet pipe 2 is communicated with a toilet sewage outlet and is used for receiving sewage of the toilet sewage outlet; the first vertical pipe 8 is communicated with a lower-layer main drainage pipeline and is used for discharging all collected sewage into a main sewage discharge pipeline. It should be noted that the upper-layer main drainage pipeline in this embodiment refers to a part of the main drainage pipeline which is located above the single vertical pipe with the building three-dimensional space as a standard; the lower level main drain pipe in this embodiment refers to the portion of the main drain pipe that is below the single riser.

In addition, in order to avoid the sewage convection caused by the different rotational flow direction of the sewage entering the first water inlet pipe 1 along the rotational flow of the upper main drainage pipeline and the rotational flow direction of the sewage entering the first water inlet pipe 1 along the rotational flow of the second water inlet pipe 2, the single vertical pipe in the embodiment further comprises a baffle 4, and the baffle 4 is arranged at the communication position of the second water inlet pipe 2 and the first water inlet pipe 1. From this, through set up baffle 4 in intercommunication department for sewage in the second inlet tube 2 can get into first inlet tube 1 according to the direction whirl of setting for, guarantees to get into the whirl direction of the sewage in first inlet tube 1 and the whirl direction of the sewage in first inlet tube 1 the same from second inlet tube 2.

In addition, when the pressure of the water flow entering the first water inlet pipe 1 along the upper layer main drainage pipeline is higher than the pressure of the water flow entering the first water inlet pipe 1 along the second water inlet pipe 2, the sewage in the first water inlet pipe 1 may be caused to reversely flow into the second water inlet pipe 2. In order to avoid the above situation, the single riser pipe in this embodiment further includes a pressure stabilizing membrane 5 disposed at a communication position of the first water inlet pipe 1 and the second water inlet pipe 2, where the material of the pressure stabilizing membrane 5 is not particularly limited, and the pressure stabilizing membrane 5 in this embodiment is made of a flexible material. When sewage in the second water inlet pipe 2 enters the first water inlet pipe 1, the pressure stabilizing film 5 does not influence the sewage to enter the first water inlet pipe 1 along the pipe wall cavity 3. When the water flow pressure in the first water inlet pipe 1 is greater than the water flow pressure in the second water inlet pipe 2, sewage in the first water inlet pipe 1 impacts the pressure stabilizing membrane 5, the pressure stabilizing membrane 5 can prevent the sewage in the first water inlet pipe 1 from being extruded into the second water inlet pipe 2, and the sewage can be stably discharged from the first vertical pipe 8 in a wall-attached rotational flow manner; when the water flow pressure in the first water inlet pipe 1 is equal to the water flow pressure in the second water inlet pipe 2, the pressure stabilizing membrane 5 is in a normal assembly state, and the discharge of pipeline sewage is not influenced; in addition, when the sewage flow rate of the second water inlet pipe 2 is large, negative pressure is formed in the second water inlet pipe 2, and the negative pressure enables the pressure stabilizing film 5 to be sunken towards the inner side of the second water inlet pipe 2 to prevent the sewage in the first water inlet pipe 1 from being sucked; similarly, when the sewage in the first water inlet pipe 1 flows at an excessively high speed, a negative pressure is formed, which may cause water sealed in the toilet to be sucked out, thereby reducing the water sealing effect of the toilet, and the pressure stabilizing film 5 is recessed towards the inner side of the first water inlet pipe 1 to prevent the sewage in the second water inlet pipe 2 from being sucked into the first water inlet pipe 1 due to the negative pressure.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
