[0003] Among them, a controllable drainage pipe is a pipe system that can achieve flow control during the drainage process. Such pipes are generally equipped with valve components to meet the drainage volume control in different situations. The valves are usually assembled by combining flanges and bolts. However, if not positioned, during the assembly process, the connection parts may shift, causing difficulties in subsequent installation. Therefore, a controllable drainage pipe is proposed.

[0036] Please refer to Figure 1 - Figure 7 , a controllable drainage pipe, including a control mechanism 101 provided on the drainage pipe body 1. The drainage pipe body 1 is located at both ends of the control mechanism 101 and is connected with a first flange 2. The control mechanism 101 is provided with second flanges 3 at both ends and is docked with the first flange 2. A second connecting collar 5 with a support outer ring 501 is provided outside the second flange 3. The outside of the first flange 2 is rotationally connected with a first connecting collar 4 with a positioning hoop 401 through threads, and the positioning hoop 401 can be tightly pressed on the support outer ring 501.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7, the controllable drainage pipe of the present application is mainly composed of a drainage pipe body 1, a control mechanism 101, a first flange 2, a second flange 3 and other structures. The control mechanism 101 is located on the pipe. The second flange 3 is installed at both ends of the pipe. The first flange 2 is installed at one end of the drainage pipe body 1 close to the control mechanism 101. The first flange 2 and the second flange 3 are in a butt-jointed state for the next operation. Before installation, a second connecting ferrule 5 with a support outer ring 501 is added outside the second flange 3. The second connecting ferrule 5 and the support outer ring 501 are integrally designed. The outer part of the first flange 2 is rotationally connected with a first connecting ferrule 4 by threads. A positioning hoop 401 is fixedly connected to the first connecting ferrule 4. When the first connecting ferrule 4 is rotated and moves towards the end close to the support outer ring 501 on the first flange 2, the end face of the positioning hoop 401 is driven to tightly press on the support outer ring 501, so that the positioning operation can be carried out between the first flange 2 and the second flange 3, avoiding the problem of deviation during the subsequent assembly of bolts in sequence, improving stability and bringing convenience to the operation process at the same time.

[0038] It should also be noted that a section of thread is provided outside the second flange 3, and this thread setting is mutually matched with the second connecting ferrule 5, enabling the second connecting ferrule 5 to be rotationally connected to its outside from one end. In this way, the second connecting ferrule 5 is connected to the outside of the second flange 3. During application, the second connecting ferrule 5 can be disassembled at any time, which is also convenient for assembly.

[0039] A limiting angle frame 301 is also provided in the present application. The limiting angle frame 301 is fixedly installed at the upper and lower ends of the tail of the second flange 3, and it is arranged on the side far from the positioning hoop 401. In this way, when the second connecting ferrule 5 is rotationally connected to the outside of the second flange 3, one end of the second connecting ferrule 5 can be restricted to avoid the problem of displacement when the mouth of the first connecting ferrule 4 is butted against the mouth of the second connecting ferrule 5.

[0040] A pressing end 402 is also provided in the present application. The positioning hoop 401 and the pressing end 402 are integrally designed. When the positioning hoop 401 tightly presses on the support outer ring 501, the provided pressing end 402 can be butted against the support outer ring 501 to improve the contact area and stability at the same time.

[0041] A stabilizing convex ring 502 is also provided in the present application. The stabilizing convex ring 502 is designed with a rubber material and is glued to the side of the support outer ring 501 that contacts the pressing end 402. When the pressing end 402 contacts the support outer ring 501, it increases the friction of the contact surface and further improves the stability of the connection.

[0042] In this application, a sealing ring member 6 is also provided. The sealing ring member 6 is arranged at the outer ring where the first flange 2 is butted against the second flange 3 to ensure the sealing effect at the connection. One end of the sealing ring member 6 is clamped in the groove of the first flange 2. Therefore, after long-term use, the sealing ring member 6 can be removed and replaced to ensure convenience.

[0043] In this application, a limiting ring 403 is also provided. The limiting ring 403 is fixedly installed on the first connecting hoop 4 at the end far from the positioning hoop 401. When the second connecting hoop 5 is rotated and connected to the outside of the first flange 2, and the positioning hoop 401 is pressed tightly against the support outer ring 501, the limiting ring 403 is driven to contact the outer ring of the second flange 3, so as to limit the first connecting hoop 4 rotating into it and perform the positioning operation, and also ensure the stability of the first connecting hoop 4 during installation.

[0044] Please refer to Figure 4 and Figure 6 , in this application, a limiting member 7 and an outer convex layer 701 are also provided. The limiting member 7 is fixedly installed at the inner ring of the limiting ring 403, which can assist in rotating and installing the first connecting hoop 4 connected to the limiting ring 403 to the outside of the first flange 2 to improve the convenience of installation. During installation, the limiting member 7 is located between the two holes after the first flange 2 and the second flange 3 are butted. Then, after being tightened with bolts and nuts, the end of the bolt is restricted in the middle part to prevent rotation; the outer convex layer 701 is evenly glued to the outer wall of the handle of the limiting member 7 and is designed with a rubber material, which can increase the frictional force between the hand and the limiting member 7 and avoid the slipping phenomenon that is likely to occur when the hand rotates.
