Description

Technical Field

[0001] The utility model relates to the technical field of assembled toilet drainage, in particular to a prefabricated drainage pipe fitting. Background Art

[0002] The assembled toilet is composed of a chassis, wall panels, and a top plate to form an overall frame, and is equipped with various functional sanitary ware. Its components are produced in the factory and assembled on site. The dry construction is conducive to the realization of residential industrialization, building industrialization, convenient installation, fast installation speed, labor saving, and quality assurance. Toilet drainage is also an important part of the bathroom. Due to the traditional construction method, that is, the bathroom with cement and yellow sand tiles, the construction process is to lay the drainage pipe first, and then carry out the construction of the wall, floor, and ceiling. Therefore, the assembled toilets on the market currently rarely involve prefabricated drainage pipes. Therefore, the utility model provides a prefabricated drainage pipe fitting with standardized production, stable and reliable quality, quick installation, and good mute effect, which can achieve convenient and quick installation, reduce operating hours, reduce noise during drainage in the bathroom, and have stable and reliable quality.

[0010] Furthermore, a cavity is preset between the pipe silent sleeve and the outer surface of the drainage lateral branch pipe and / or the drainage connecting pipe fitting, and the hollow structure can effectively enhance the effect of silent noise reduction.

[0011] Furthermore, the structure of the pipe silent sleeve is a spiral silent protective sleeve, and the spiral twisted structure is wrapped around the pipe, thereby increasing the volume of the cavity between the pipe silent sleeve and the outer surface of the drainage branch pipe and / or the drainage connecting pipe, which can effectively promote the silent effect.

[0013] Furthermore, the structure of the pipe silent cover is a self-rolling silent protective cover, which is easy to install. It has a self-rolling property and can quickly shrink and wrap the drainage pipe fittings, thereby enhancing the reliability of the connection between the pipe silent cover and the drainage pipe fittings.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Embodiment 1

The bathroom drainage pipe fittings are prefabricated in the factory according to the design requirements and assembled on site to achieve convenient and fast installation, reduce operation hours, unify the prefabrication operation process standards, and achieve stable and reliable quality of the drainage pipe fittings.

[0028] The prefabricated drainage pipe fittings provided by the utility model mainly include a drainage lateral branch pipe 1, a drainage connecting pipe fitting 2, a pipe sealing sleeve 3, and a pipe silent sleeve 4;

[0029] The drainage lateral branch pipe 1 is sealed and connected to the drainage connecting pipe 2. The connection method in this embodiment is plastic pipe adhesive connection;

[0030] The pipe sealing sleeve 3 is arranged at the connection between the drainage transverse branch pipe 1 and the drainage connecting pipe fitting 2, and the pipe sealing sleeve 3 is sealed and connected to the drainage transverse branch pipe 1. The pipe sealing sleeve 3 is sealed and connected to the drainage connecting pipe fitting 2 to ensure the stability of the connection between the drainage transverse branch pipe 1 and the drainage connecting pipe fitting 2, improve the reliability of the connection between the drainage transverse branch pipe 1 and the drainage connecting pipe fitting 2, and can effectively prevent water leakage and seepage; the pipe sealing sleeve 3 is a soft shrinkage material, which is different from the traditional pipe glue adhesive. On the basis of the sealed connection between the drainage transverse branch pipe 1 and the drainage connecting pipe fitting 2, a secondary seal is performed to achieve the effect of double protection, reduce leakage caused by failure to fully seal due to construction operation errors and leakage at the connection between the drainage transverse branch pipe 1 and the drainage connecting pipe fitting 2 due to vibration generated by long-term use, and can effectively improve the reliability of the connection between the drainage transverse branch pipe 1 and the drainage connecting pipe fitting 2.

[0031] The pipe silent sleeve 4 is prefabricated on the outer surface of the drainage lateral branch pipe 1 and / or the drainage connecting pipe 2, which can effectively reduce the operation time on the construction site.

[0032] A cavity A is preset between the pipe silent sleeve 4 and the outer surface of the drainage lateral branch pipe 1 and / or the drainage connecting pipe 2, and the hollow structure can effectively enhance the silent noise reduction effect.

[0033] In this embodiment, the structure of the pipe silent sleeve 4 is a spiral silent protective sleeve, and the spiral twisted structure is wrapped around the pipe, which increases the volume of the cavity A between the pipe silent sleeve 4 and the outer surface of the drainage lateral branch pipe 1 and / or the drainage connecting pipe 2, and can effectively promote the silent effect. Two adjacent spiral pipe silent sleeves 4 are connected by overlapping, which enhances the reliability of the connection of the pipe silent sleeves 4 and facilitates the installation operation. Embodiment 2

[0034] Different from the above-mentioned embodiment 1, the structure of the pipe silent cover 4 in the utility model is a self-rolling silent protective cover, which is easy to install. It has a self-rolling property and can quickly shrink and wrap the drainage pipe fittings, thereby enhancing the reliability of the connection between the pipe silent cover 4 and the drainage pipe fittings.

[0036] Preferably, the drainage lateral branch pipe 1 is connected with a reducing connecting pipe 5, which is suitable for various construction scenarios and has a good market prospect.

[0037] To sum up, a prefabricated drainage pipe fitting can prefabricate the drainage pipe fittings in a unified manner in the factory according to the design drawings and perform standardized operations, thereby reducing the operation hours at the construction site and reducing the unstable quality caused by the technical level of on-site construction personnel or operational errors. The drainage pipe fittings of the utility model are provided with double anti-leakage pipe sealing sleeves at the connection points, and a physical protection structure is adopted, which is different from the traditional pipe glue adhesive to achieve secondary sealing, effectively reducing leakage caused by failure to fully seal due to construction operation errors and leakage at the connection points between the drainage branch pipe and the drainage connecting pipe fittings due to vibration generated by long-term use, and can effectively improve the reliability of the connection points between the drainage branch pipe and the drainage connecting pipe fittings. The drainage pipe fittings of the utility model are prefabricated with silent protective sleeves, which reduces the operation hours at the construction site, and the silent protective sleeves can enhance the effect of silent noise reduction while reducing the loosening of the drainage pipe caused by the vibration generated by drainage and the waterproof structure. The drainage pipe fittings of the utility model are prefabricated in the factory, which supplements the system mode of operating the assembled toilet drainage pipes at the construction site, solves the problem of spending a lot of man-hours on the on-site silent noise reduction treatment of the drainage pipes, and solves the problem of water leakage and seepage at the connection points of the common drainage pipe fittings on the market. Therefore, the utility model has a good market prospect.
