For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.
[0034] Example 1
[0035] This embodiment provides a drainage riser system, including:
[0036] A plurality of riser sections 1-1 are connected in sequence to form a drainage riser 1; wherein two adjacent riser sections 1-1 are connected via a tee 2, and the tee 2 is used to connect the delivery pipes of sanitary appliances 4 and / or floor drains 3; the drainage riser 1 of this embodiment is used in high-rise buildings, with one riser section 1-1 corresponding to one floor of the building, and then two adjacent riser sections 1-1 are connected at their connection points via a tee 2, so that the two adjacent riser sections 1-1 form a connected integrated pipeline, and the riser 1-1 and the tee 2 are both pipelines and pipeline connectors used in existing high-rise building drainage riser systems.
[0037] A plurality of spacers 6 are respectively arranged in the multi-section riser 1-1; wherein the spacers 6 are arranged along the axial direction of the riser 1-1, and the spacers 6 are used to separate the riser 1-1 into a drainage pipe 1-3 and an air pressure regulating pipe 1-2, and a plurality of vents 6-1 are arranged on the spacer 6, and the plurality of vents 6-1 are evenly distributed along the axial direction of the riser 1-1, and the vents 6-1 are connected to the drainage pipe and the air pressure regulating pipe; after the riser 1-1 of this embodiment is separated into the drainage pipe and the air pressure regulating pipe by the spacer 6, the tee pipe 2 conveys the sanitary ware 4 and / or the floor drain 3 The sewage transmitted by the pipe is transported to the drain pipe, and the drain pipe transports the sewage to the septic tank; the spacer 6 is a partition made of the same material as the vertical pipe 1-1, and the partition can be a flat plate, an arc plate or other different structures. Considering that the vertical pipe 1-1 is mainly used to transport sewage to the septic tank, the cross-sectional areas of the drain pipe and the air pressure regulating pipe formed by the spacer 6 are different. The cross-sectional area of the drain pipe is larger than that of the air pressure regulating pipe. The air pressure regulating pipe only needs to balance the air pressure difference of the entire vertical pipe 1-1 so that the odor will not be reversed to the user's room, so it does not need to occupy much volume of the vertical pipe.
[0038] A connecting piece 7 is provided in the tee pipe 2, and the two ends of the connecting piece 7 are respectively connected to two adjacent spacers 6 to form an integrated structure. Considering that the tee pipe 2 is in a position connected to the sanitary ware 4 and / or the floor drain 3, the tee pipe 2 is also divided into two areas to prevent the sewage transported by the sanitary ware 4 and / or the floor drain 3 from entering the air pressure regulating pipe from the tee pipe 2, causing the air pressure regulating pipe to be blocked. The structure of the connecting piece 7 can be consistent with the spacer 6.
[0039] The spacer 6 and the connector 7 of this embodiment can be bonded to the vertical pipe by glue for pipe connection, and the spacer 6 and the connector 7 can also be bonded by glue, for example:
[0040] Ordinary PVC glue: This glue is specially designed for PVC pipe connections, with excellent adhesion and durability, and can form seamless connections.
[0041] PVC special glue: This glue is optimized for the characteristics of PVC materials, has good bonding effect, and is suitable for connecting PVC pipes.
[0042] HDPE polyethylene special glue: This glue is suitable for connecting HDPE pipes to PVC pipes and can effectively bond the two materials together.
[0043] Epoxy resin adhesive: This type of glue is suitable for scenarios requiring high-strength bonding and has good mechanical properties and durability.
[0044] The corresponding glue can be selected according to the preparation materials of the spacer 6 and the connecting member 7 .
[0045] Principle: In this embodiment, a drainage riser system is provided in which a spacer 6 is provided in the pipe of the drainage riser 1 to separate the riser 1-1 into a drainage pipe and an air pressure regulating pipe, and a vent 6-1 is provided on the spacer 6. When sewage is discharged from the high-rise building to the septic tank located underground, the riser 1-1 located at the high-rise is blocked by sewage. During the process of the pipe to the low-rise riser 1-1, the sewage squeezes the gas in the low-rise riser 1-1, so that the air pressure of the low-rise riser 1-1 increases. At this time, since the drainage pipe and the air pressure regulating pipe are interconnected, the air pressure in the low-rise riser 1-1 increases. Therefore, the gas in the drainage pipe can flow into the air pressure regulating pipe, and then flow to the high-rise riser 1-1, so that the air pressure of the low-rise riser 1-1 is reduced. At this time, the air pressure of the low-rise riser 1-1 is regulated, so it will not be greater than the sum of the indoor air pressure of the low-rise user and the maximum water pressure difference on both sides of the water trap, avoiding the gas in the riser 1-1 from flowing through the tee pipe 2 to the water trap set in the sanitary ware 4 and / or the floor drain 3, entering the user's room through the water trap of the sanitary ware 4 and / or the floor drain 3 in the form of bubbles, and floating in the room in the form of aerosol.
[0046] In some embodiments, the connector 7 includes a buffer section 7-1 and a guide section 7-2, one end of the buffer section 7-1 and the guide section 7-2 are fixedly connected to form an integral structure, and the other ends of the buffer section 7-1 and the guide section 7-2 are respectively connected to two adjacent spacers 6 to form an integral structure, and an angle is formed between the buffer section 7-1 and the guide section 7-2. Considering that the connector 7 needs to withstand the impact of sewage discharged from the sanitary ware 4 and / or the floor drain 3, the buffer section 7-1 is arranged at a position facing the impact to buffer the impact force, and the guide section 7-2 guides the discharged sewage to the riser 1-1. By such an arrangement, the connector 7 can be protected from being damaged or falling off.
[0047] In some embodiments, the buffer section 7-1 is tilted, one end of the buffer section 7-1 is higher than the connection between the tee pipe 2 and the drain pipe, the distance from one end of the buffer section 7-1 to the connection between the tee pipe 2 and the drain pipe is a, and the distance from the other end of the buffer section 7-1 to the connection between the tee pipe 2 and the drain pipe is b, a<b. By tilting the buffer section 7-1, the impact force of sewage impacting the buffer section 7-1 can be reduced.
[0048] In some embodiments, the vent hole 6-1 is tilted, and the port of the vent hole 6-1 located at the air pressure regulating pipe is higher than the port located at the drain pipe. Through the vent hole 6-1 arranged in this way, the sewage transmitted in the drain pipe will not flow to the air pressure regulating pipe, while the gas can flow smoothly to the air pressure regulating pipe, thereby preventing the air pressure regulating pipe from being blocked.
[0049] In some embodiments, the three-way pipe 2 includes a first connecting pipe 2-2 and a second connecting pipe 2-1, one end of the first connecting pipe 2-2 is used to connect the delivery pipe of the sanitary ware 4 and / or the floor drain 3; the other end of the first connecting pipe 2-2 is connected to the second connecting pipe 2-1; wherein, a one-way opening and closing baffle 8 is provided in the first connecting pipe 2-2; the two ends of the second connecting pipe 2-1 are respectively connected to two adjacent sections of the vertical pipe 1-1, wherein the connecting piece 7 is provided in the second connecting pipe 2-1. In order to further ensure that the gas in the vertical pipe 1-1 will not be transmitted from the sanitary ware 4 and / or the floor drain 3 to the user's room, a one-way opening and closing baffle 8 is provided at the connection between the three-way pipe 2 and the sanitary ware 4 and / or the floor drain 3, so that the sewage transmitted by the sanitary ware 4 and / or the floor drain 3 can enter the vertical pipe 1-1 from the three-way pipe 2, while the gas in the vertical pipe 1-1 is blocked by the baffle 8 and cannot enter the sanitary ware 4 and / or the floor drain 3, and thus cannot enter the user's room.
[0050] In some embodiments, a retaining ring 8-1 is provided in the first connecting pipe 2-2, a hinge is provided on the retaining ring 8-1, and the retaining piece 8 is connected to the hinge to open and close relative to the retaining ring 8-1. The retaining ring 8-1 is a circular ring structure, which fits the inner wall of the first connecting pipe 2-2, and a through hole 8-4 is provided in the middle of the retaining ring 8-1 for the sewage transported by the sanitary ware 4 and / or the floor drain 3 to pass through.
[0051] In some embodiments, the hinge is a hinge structure. The baffle 8 rotates along the hinge axis, and the retaining ring 8-1 blocks the baffle 8 from rotating toward the sanitary ware 4 and / or the floor drain 3, so the baffle 8 can only be flushed open by the sewage transported by the sanitary ware 4 and / or the floor drain 3, while the gas transmitted from the riser 1-1 cannot push the baffle 8 open to transmit gas to the sanitary ware 4 and / or the floor drain 3, so it can be further ensured that the gas in the riser 1-1 will not be transmitted from the sanitary ware 4 and / or the floor drain 3 to the user's room.
[0052] Example 2
[0053] The present embodiment provides a drainage riser system, whose hinged parts include a support shaft 8-3 and a hinged seat. There are two hinged seats, which are spaced apart on a retaining ring 8-1. Both ends of the support shaft 8-3 are rotatably connected to the two hinged seats respectively, and the retaining plate 8 is fixedly connected to the support shaft 8-3.
[0054] In the above embodiment, the baffle 8 includes a baffle 8 body and a protrusion, the baffle 8 body is connected to the hinge, and the protrusion is adapted to the through hole 8 - 4 .
[0055] The remaining structures are consistent with those in the embodiment and will not be described in detail here.
[0056] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of explanation and illustration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
