[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A convenient replacement sewage pipe valve: comprising a valve body 1, one end of the valve body 1 is flange-connected to a first sewage pipe 11, the other end of the valve body 1 is flange-connected to a second sewage pipe 12, a limiting mechanism is arranged on the surface of the valve body 1, the limiting mechanism comprises a rotating seat 2, the rotating seat 2 is fixedly connected to the surface of the valve body 1, a rotating rod 21 is rotatably connected to the surface of the rotating seat 2, a connecting pipe 22 is fixedly connected to the surface of the rotating rod 21, an externally threaded pipe 23 is fixedly connected to the surface of the connecting pipe 22, and the first sewage pipe 11 and the second sewage pipe 12 are both movably connected to the surfaces of the first sewage pipe 11 and the second sewage pipe 12. A movable tube 24 is provided, on the surface of which an internal threaded tube 25 is fixedly connected; a limiting block 26 is fixedly connected on the surfaces of the first sewage pipe 11 and the second sewage pipe 12; a bolt 27 is perforated and connected on the surface of the rotating seat 2; a nut 28 is threadedly connected on the surface of the bolt 27; and a limiting mechanism thereof can provide limited support for the valve body 1 on the first sewage pipe 11 and the second sewage pipe 12, without the need for manual adjustment of the position of the valve body 1, thereby improving the installation speed of the valve body 1 on the first sewage pipe 11 and the second sewage pipe 12 and thereby ensuring the replacement efficiency of the valve body 1.

[0024] Furthermore, four groups of rotating rods 21 are provided, and grooves are opened on the surface of the rotating seat 2. The rotating rods 21 rotate on the grooves of the rotating seat 2. The rotating rods 21 rotate on the surface of the valve body 1 through the rotating seat 2. Under the restriction of the rotating seat 2, the rotating rods 21 can only rotate one hundred and eighty degrees.

[0025] Furthermore, a circular hole is opened on the surface of the rotating seat 2, and a circular hole is opened on the surface of the rotating rod 21. The circular hole of the rotating seat 2 is connected to the groove of the rotating seat 2. The bolt 27 penetrates the circular holes of the rotating seat 2 and the rotating rod 21 and is threadedly connected with the nut 28. The circular hole of the rotating rod 21 rotates on the bolt 27, thereby realizing rotation on the groove of the rotating seat 2. When the bolt 27 is removed from the rotating seat 2, the rotating rod 21 can be removed from the rotating seat 2.

[0026] Furthermore, the connecting pipe 22 and the externally threaded pipe 23 are rotated on the surface of the valve body 1 through the rotating rod 21. The connecting pipe 22 and the externally threaded pipe 23 are in a semi-tube shape. The connecting pipe 22 can be rotated on the valve body 1 until it contacts and connects to the surface of the first sewage pipe 11 or the second sewage pipe 12. The inner circle diameter of the connecting pipe 22 is the same as the outer circle diameter of the first sewage pipe 11 and the second sewage pipe 12, so that the connecting pipe 22 can be tightly contacted and connected to the outer surface of the first sewage pipe 11 or the second sewage pipe 12 after the rotation is completed.

[0027] Furthermore, a slot is provided on the surface of the limit block 26 , and the rotating rod 21 is engaged with the slot of the limit block 26 . The limit block 26 limits the installation angle of the valve body 1 through the rotating rod 21 .

[0028] Furthermore, four groups of connecting pipes 22 and externally threaded pipes 23 are provided, and the connecting pipes 22 and externally threaded pipes 23 will form a whole pipe shape on the first sewage pipe 11 or the second sewage pipe 12. The connecting pipes 22 and externally threaded pipes 23 limit the installation position of the valve body 1 through the rotating rod 21, thereby eliminating the need for workers to adjust the installation position of the valve body 1.

[0029] Furthermore, the internal threaded tube 25 rotates and slides on the first sewage pipe 11 or the second sewage pipe 12 through the movable tube 24, and the internal threaded tube 25 is simultaneously threadedly connected to two groups of external threaded tubes 23. The internal threaded tube 25 limits the rotation of the rotating rod 21 on the valve body 1 through the external threaded tube 23, thereby limiting the rotation of the connecting tube 22, and the connecting tube 22 limits the installation position of the valve body 1 on the first sewage pipe 11 and the second sewage pipe 12 through the rotating rod 21.

[0030] Working principle: by rotating the rotating rod 21 on the valve body 1, the rotating rod 21 drives the connecting pipe 22 and the external threaded pipe 23 to rotate on the valve body 1, so that the rotating rod 21 will be engaged and connected to the slot of the limit block 26, and the two groups of connecting pipes 22 are rotated to contact and connect with the first sewage pipe 11 or the second sewage pipe 12, and the two groups of connecting pipes 22 are also contacted and connected with each other, and the two groups of external threaded pipes 23 are also contacted and connected with each other. At this time, the two groups of internal threaded pipes 25 are driven to rotate on the first sewage pipe 11 or the second sewage pipe 12 through the movable pipe 24, so that the internal threaded pipe 25 is threadedly connected to the external threaded pipe 23, and the internal threaded pipe 25 limits the position of the two groups of external threaded pipes 23, and The two groups of external threaded tubes 23 limit the position of the valve body 1 through the connecting tube 22 and the rotating rod 21, so there is no need to manually adjust the position of the valve body 1, making the valve body 1 more convenient to install, improving the installation efficiency of the valve body 1, and also strengthening the connection strength of the valve body 1. Since the flange hole of the valve body 1 and the rotating rod 21 are misaligned, the rotating rod 21 will not affect the flange installation process of the rotating rod 21. At the same time, the rotating rod 21 is rotated on the rotating seat 2 by the bolt 27. The bolt 27 can be removed from the circular hole of the rotating seat 2 by the nut 28. At this time, the rotating rod 21 is removed from the rotating seat 2, which is convenient for the reuse of the limiting mechanism parts and reduces resource consumption.
