Closestool water outlet connecting pipe and installation method thereof

Abstract

The invention provides a closestool water outlet connecting pipe and an installation method thereof, belongs to the technical field of closestool installation accessories, and solves the problems of difficult closestool installation, poor sealing performance and the like in the prior art. The closestool water outlet connecting pipe comprises a pipe body, the top of the pipe body is used for beingconnected with a closestool water outlet, the bottom of the pipe body is used for being inserted into a drainage pipeline, and the top end of the pipe body is provided with a connecting face for gluing. The connecting surface of the pipe body and the water outlet at the bottom of the closestool are bonded and fixed by colloid; the installation process of the closestool becomes very easy, and the sealing effect o the colloid is good without looseness; due to the fact that the connecting face is connected with the bottom of the closestool in a sealed mode and the pipe body is arranged at the bottom of the closestool in a sleeving mode, the closestool water outlet connecting pipe can be suitable for various closestools with the outer diameters of water outlets smaller than the inner diameterof the top of the pipe body, and even if the installation is inclined due to slight deviation, the connecting face keeps sealed all the time, and the error-tolerant rate is high; a necking section isarranged to be in a downward necking arc shape, and an inserting section is arranged to be in a straight cylinder shape, so that the connecting pipe can be installed on drainage pipelines with different inner diameters.

Description

technical field [0001] The invention belongs to the technical field of toilet installation accessories, and in particular relates to a toilet outlet connecting pipe and an installation method thereof. Background technique [0002] During the traditional toilet installation process, the bathroom is pre-buried with a sewer pipe, and the drain of the toilet is connected to the sewer pipe, and a flange connection needs to be installed between the toilet drain and the sewer pipe, which is easy to shift and block; , cement, wax ring and other bonding materials to seal the joint between the toilet drainage and the sewer pipe. However, in the actual use process, the sealing effect of bonding materials such as butter, cement, and wax rings is not ideal. The characteristics of bonding materials that are cold and soft when exposed to heat make the sealing effect easily affected by the surrounding temperature and drainage water temperature. It is easy to have the problem of water leaka...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned comparative document does not use the bonding material for traditional toilet installation, it uses an integral sealing ring. Firstly, the main body of the sealing ring is inserted into the sewer pipe, and then a connecting pipe is set at the toilet outlet, and the connecting pipe is inserted into the main body of the sealing ring to form a Sealing, because the toilet drain is small and the toilet is heavy, the bottom interface is not easy to be intuitive, it is extremely difficult to align during installation, it is very inconvenient, the fault tolerance rate is low, it is easy to cause unnecessary friction damage, and it is easy to shift; in addition, the sealing ring Embedded in the drainpipe, the end of the drainpipe is required to be flat and there should be no difference in height. The drainpipe is installed underground, and the construction personnel need to cut the end of the drainpipe. During construction, the end of the drainpipe cannot be cut smoothly. The height difference will inevitably lead to the installation of the sealing ring is not firm. At the same time, the unevenness of the sealing ring will cause the toilet outlet pipe to connect to the sealing ring unevenly, leaving a space and causing water leakage. It is connected with the two parts of the sealing ring, and a slight deviation between the two parts will cause water leakage, and the connecting pipe installed on the toilet outlet needs to be closed to facilitate docking with the sealing ring, and the closing will cause water flow impact If the sealing ring is not installed firmly, it will be more difficult to ensure the assembly relationship between the two joints. Long-term water flow impact and sewage pollution will also cause the sealing ring to loosen and aging, which will affect the service life.
