Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage fittings, in particular to a drainage sealing ring with a flip structure for sealing. Background Art
[0002] Drainage fittings refer to devices that are located between sanitary appliances and building drainage pipes in a drainage system and are used to control and convey wastewater from the bottom of sanitary appliances to the building drainage pipes. Drainage fittings are composed of drainage elbows, connectors, and sealing components.
[0003] Drainage fittings for washbasins and kitchen sinks are generally finished products and are provided by appliance manufacturers. They include appliance drain pipes and water seal devices. When installed, the drain pipe outlet of the drainage fitting (hereinafter collectively referred to as the appliance drain pipe) is directly inserted into the interface reserved in the building drainage system pipe. There is a large gap between the appliance drain pipe and the connection after insertion. When the trap is located upstream of the interface, strict sealing measures must be taken for this gap to prevent harmful gases in the drainage pipe system from escaping into the room.
[0004] Currently, the main sealing methods are as follows:
[0005] 1) Teflon tape is wound around the outside of the appliance drain pipe to plug the gap, which plays a main sealing role. On the ground, it is covered with a cover, and the gap of the cover is sealed with mildew-proof silicone.
[0006] 2) Epoxy putty is used to fill the gap between connecting pipes, and at the same time, the depth of insertion of the appliance drain pipe into the reserved interface is specified as 50 mm.
[0007] However, the existing sealing methods require on-site treatment by operators, and the sealing effect depends on the level of the operators. There are problems such as poor quality stability. The airtight performance after connection depends on the quality of the installation operators, and it is difficult to guarantee the overall construction quality. In many cases, the appliance drain pipe is directly inserted into the interface without any caulking and airtight measures, and only a cover is added on the external ground. The cover only has a decorative function and cannot play a tight sealing role. Summary of the Invention
[0008] The utility model mainly solves the deficiencies existing in the prior art, and provides a drainage sealing ring with a flip structure for sealing, which has the characteristics of simple structure, convenient operation, and good sealing effect. It solves the problem of poor airtight performance of the sealing ring. It avoids the toxic and harmful gases in the drainage system pipe from escaping into the room under pressure, causing health and safety hazards.
[0009] The above technical problems of the utility model are mainly solved by the following technical solutions:
