Description
Technical Field
[0001] The invention belongs to the technical field of drainage pipes, and relates to a drainage pipe device with an expandable interface. Background Art
[0002] With the development of science and technology and the improvement of people's living standards, existing kitchens are generally equipped with sinks, dishwashers, pre-filters and other equipment. All of the above equipment need to be connected to the drain outlet for drainage, but there is usually only one drain outlet on the floor of the kitchen. The existing practice is to use a drain pipe with multiple connecting ports to connect the drain outlet, and then connect the drain outlets of the sink, dishwasher, pre-filter and other equipment in the kitchen to the connecting ports of the drain pipe to achieve drainage of the above equipment. However, the above practice has the following shortcomings: every time a new equipment is added to the kitchen (such as a kitchen treasure, etc.), the original drain pipe needs to be replaced with a new drain pipe with more connecting ports, and then the original equipment and the newly added equipment are respectively connected to the connecting ports of the new drain pipe, which is inconvenient to operate. In addition, when in use, the odor in the drain pipe is easy to float out from the drain outlet of the sink and spread to the kitchen, resulting in poor air quality in the kitchen. Summary of the invention
[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose a drainage pipe device with an expandable interface. The technical problem to be solved by the utility model is to provide a drainage pipe device with an expandable interface to facilitate the expansion of the drainage pipe connection port and have an anti-odor function.
[0004] The purpose of the utility model can be achieved through the following technical solutions:
[0005] A drainage pipe device with an expandable interface comprises a main drainage pipe, characterized in that the main drainage pipe is provided with a one-way valve that can make the water flow in the pipe unidirectional from top to bottom, and the upper inner wall of the main drainage pipe is provided with a sealing sleeve, and the lower outer wall of the main drainage pipe is provided with a sealing ring, and the side wall of the main drainage pipe is provided with two cylindrical main connecting ports, each of which is connected to at least one three-way pipe fitting in series, and the three-way pipe fitting located at the outermost side of one of the main connecting ports is connected to an elbow pipe fitting, and the three-way pipe fitting located at the outermost side of the other main connecting port is detachably provided with a pipe plug; the main connecting port, the three-way pipe fitting and the elbow pipe fitting are all provided with convex strips for position reference, and when any two adjacent convex strips are arranged relative to each other, the main drainage pipe, the three-way pipe fitting and the elbow pipe fitting are located on the same vertical plane.
[0006] The pipe plug of the drainage pipe device with an expandable interface can play a plugging role with good sealing effect, preventing the water flow in the drainage pipe device with an expandable interface from leaking from here, and the use cost of the pipe plug is low, and the elbow pipe fitting can change the flow direction of the water. Because the elbow pipe fitting has only two ends, after connecting the equipment drainage pipe, the bending part of the elbow pipe fitting can also play an indirect plugging role, thereby directing the water flow to the main drainage pipe. At the same time, the pipe plug adopts a detachable setting, so that after removing the pipe plug, one or more three-way pipe fittings can continue to be glued and connected in series at this port for the newly added equipment to connect and drain, and the end of the newly set three-way pipe fitting continues to be sealed with the pipe plug, which can greatly facilitate the expansion of the drainage pipe connection port, that is, by setting the pipe plug, it is always possible to add electrical appliances or A drainage interface is left in the pipeline to facilitate the connection of newly added equipment with the drain pipe; at the same time, the sealing sleeve can seal the connection between the hose and the main drain pipe, the sealing ring can seal the connection between the main drain pipe and the drain outlet, and the one-way valve can prevent the odor in the main drain pipe from floating up from the bottom to the top of the sink drain outlet and diffusing into the kitchen, so that the drain pipe device with an expandable interface can effectively prevent odor when in use; in addition, by providing a convex strip for position reference during adhesive connection, it can better ensure that the main drain pipe, tee pipe fitting and elbow pipe fitting are located on the same vertical plane after connection, thereby saving the installation space required for the drain pipe device with an expandable interface, and making the drain pipes of each device look more orderly after connection, and can also greatly facilitate the connection operation when the drain pipe connection port is expanded.
[0007] In the above-mentioned drain pipe device with an expandable interface, a butterfly handle plug is threadedly connected to the upper port of the three-way pipe fitting with a pipe plug, and the upper ports of the other three-way pipe fittings and elbow pipe fittings are threadedly connected to quick connectors. The butterfly handle plug is a reserved drain port, and after removing the butterfly handle plug, the drain pipe of the newly added equipment can be connected here, which is more convenient to use. At the same time, by setting a quick connector, the drain pipe device with an expandable interface can be quickly connected to the drain pipes of various equipment, which is more convenient, quick and labor-saving to use.
[0008] In the above-mentioned drainage pipe device with expandable interface, the main connection port and the three-way pipe fitting, the three-way pipe fitting and the three-way pipe fitting, and the three-way pipe fitting and the elbow pipe fitting are all connected by adhesive. The adjacent main drainage pipes, three-way pipe fittings and elbow pipe fittings are all connected by adhesive, which is more convenient to operate, faster to connect, and has low cost compared to welding, hot melt connection and flange connection. At the same time, compared with the threaded connection, the connection has better sealing and corrosion resistance, and is not prone to leakage and corrosion.
[0009] In the above-mentioned drain pipe device with an expandable interface, there are multiple sealing rings, the ring widths of the multiple sealing rings are different and they are spaced apart from each other along the axial direction of the main drain pipe. By setting multiple sealing rings with different ring widths, the drain pipe device with an expandable interface can be directly adapted to drain pipes of various diameters, so that the versatility of the drain pipe device with an expandable interface is better. For example, when the outer wall of the main drain pipe is embedded with a large sealing ring that can be adapted to a large-diameter drain pipe and a small sealing ring that can be adapted to a small-diameter drain pipe, in actual use, when the drain pipe is of a small diameter, it is only necessary to remove the large sealing ring, and then directly insert the main drain pipe with the small sealing ring retained into the drain pipe; when the drain pipe is of a large diameter, the small sealing ring can be removed and only the large sealing ring can be retained, or both the large sealing ring and the small sealing ring can be retained, and the main drain pipe can be directly inserted into the drain pipe, but the small sealing ring does not work at this time.
[0010] In the above-mentioned drain pipe device with an expandable interface, the outer wall of the main drain pipe has an outwardly protruding and annular abutment portion, the abutment portion is located below the main connection port, and the sealing ring is located below the abutment portion. The abutment portion is arranged to abut against the top of the drain pipe to prevent the drain pipe device with an expandable interface from axial displacement, and the annular abutment portion can further seal the connection between the main drain pipe and the drain pipe, so that the drain pipe device with an expandable interface has a better deodorizing effect when in use.
[0011] In the above-mentioned drain pipe device with an expandable interface, the inner wall of the sealing sleeve has an annular step portion, and the inner wall surface of the sealing sleeve located above the annular step portion is inclined from bottom to top toward the main drain pipe. The annular step portion can be used for the hose connected to the drain outlet of the sink to abut against, ensuring the insertion depth of the hose, and also preventing the hose from being inserted too deep or too shallow, and the inner cavity of the sealing sleeve located above the second annular step portion is expanded, which can facilitate the insertion of the hose on the one hand, and on the other hand, the narrowed part of the inner cavity of the sealing sleeve can form a tight fit with the hose, making the hose insertion more secure, and allowing the hose and the sealing sleeve to form a better abutment seal, preventing the smell in the main drain pipe from leaking from the connection, so that the drain pipe device with an expandable interface has a better deodorizing effect when in use.
[0012] Compared with the prior art, the advantages of the drain pipe device with an expandable interface are: 1. After removing the butterfly handle plug, the drain pipe of the newly added equipment can be connected here. Furthermore, after removing the pipe plug, one or more three-way pipe fittings can be glued and connected in series here for the newly added equipment to connect drainage, thereby greatly facilitating the expansion of the drain pipe connection port, that is, a drainage interface can always be reserved for the electrical appliances or pipelines to be added.
[0013] 2. The sealing sleeve of the drain pipe device with an expandable interface can seal the connection between the hose and the main drain pipe, the sealing ring can seal the connection between the main drain pipe and the drain outlet pipe, and the one-way valve can prevent the odor in the main drain pipe from floating up from the bottom to the top of the drain outlet of the sink and spreading into the kitchen, so that the drain pipe device with an expandable interface can effectively prevent odor when in use.
