[0016] Among them, 1-conversion joint body, 2-flange, 3-separation convex ring, 4-support sleeve, 5-sealing ring, 6-gasket; 7-pressure cover, 8-PE drain pipe, 9-PVC drain pipe. DETAILED DESCRIPTION

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] The structure of the device provided in this embodiment for solving the problem of connecting pipe drainage systems of different materials is as follows: Figure 1 As shown, it includes a conversion joint body 1 and a sealing assembly.

[0019] A flange 2 is provided at one end of the conversion joint body 1, and the function of the flange 2 is to install the sealing component. A separation convex ring 3 is provided at the middle part of the inner wall of the conversion joint body 1, and the function of the separation convex ring 3 can be used as a reminder. When the PE drainage pipe 8 and the PVC drainage pipe 9 are inserted into the conversion joint body 1, through the contact connection with the separation convex ring 3, it can be known that the PE drainage pipe 8 and the PVC drainage pipe 9 have been inserted to the most suitable position.

[0020] The sealing assembly includes a support sleeve 4, a sealing ring 5, a gasket 6 and a gland 7. One end of the support sleeve 4 is connected to the middle part of the flange 2, and the support sleeve 4 is perpendicular to the flange 2. An external thread is provided on the outer wall of the support sleeve 4. The sealing ring 5 is located in the support sleeve 4, and one end face of the sealing ring 5 is in contact with the flange 2. The gasket 6 is located in the support sleeve 4, and one end of the gasket 6 is in contact with the other end face of the sealing ring 5. The function of the gasket 6 is to prevent friction between the gland 7 and the sealing ring 5 when rotating during the installation process, thereby damaging the sealing ring 5 and affecting the construction.

[0021] The gland 7 is J-shaped. The inner wall of the longer side of the gland 7 is provided with internal threads, and the longer side of the gland 7 is threadedly connected to the support sleeve 4. The bent portion of the gland 7 is in contact connection with the other end of the support sleeve 4, and the end of the shorter side of the gland 7 is in contact connection with the other end face of the washer 6.

[0022] The usage method of the above device for solving the connection of drainage systems of different materials is as follows:

[0023] When connecting the PVC drainage and PE drainage systems, after chamfering and applying lubricant to the PE drainage pipe 8, it is inserted into the conversion joint body 1 from the top cover until the PE drainage pipe 8 abuts against the partition convex ring 3. Apply special PVC glue to the outer wall of the insertion end of the PVC drainage pipe 9, and then insert the insertion end of the PVC drainage pipe 9 into the other end of the conversion joint body 1 until the PVC drainage pipe 9 abuts against the partition convex ring 3, as Figure 2 shown. It can be seen that the connection of the PVC and PE drainage systems can be realized through this device.
