Referring to fig. 1, the housing 1 may be a cylindrical tube with two open ends, i.e., a first port 4 and a second port 5 opposite to the first port 4, respectively, and a tube cavity is formed between the first port 4 and the second port 5. The first port 4 and the second port 5 are provided with a connecting flange 9, respectively.

Referring to fig. 2, the cavity of the housing 1 is divided into three separate chambers, namely a first chamber 6, a second chamber 7 and a third chamber 8, wherein the first chamber 6 has a mouth, the mouth of the first chamber 6 is located at the first port 4, the second chamber 7 has a mouth, the mouth of the second chamber 7 is located at the second port 5, the third chamber 8 has two mouths, and the two mouths of the third chamber 8 are located at the first port 4 and the second port 5, respectively.

Referring to fig. 1-2, the interior of the housing 1 is divided into a first chamber 6, a second chamber 7 and a third chamber 8 by two partition walls 10. For example, referring to fig. 3, the partition plate 10 includes a rectangular plate 11 and an inclined plate 12 connected to the rectangular plate 11. Preferably, the rectangular plate 11 and the inclined plate 12 are of an integral structure and may be formed by bending a metal plate. The rectangular plate 11 intersects the sloping plate 12 at an obtuse angle. The baffle 10 has opposed first and

second sides

14, 15, a third side 16 connecting the first and

second sides

14, 15, and a curved side 17. The housing 1 is cylindrical and the curved edge 17 can closely fit the inner wall of the housing 1, for example, the curved edge 17 may be an elliptical line. The first side 14, the second side 15, the third side 16 and the intersection 18 of the rectangular plate 11 and the sloping plate 12 define the rectangular plate 11, and the curved side 17 and the intersection 18 of the rectangular plate 11 and the sloping plate 12 define the sloping plate 12.

A partition 10 is provided in the housing 1. Specifically, the rectangular plate 11 extends from the port of the housing 1 into the housing 1 in the axial direction of the housing 1, and two opposite sides of the rectangular plate 11, for example, the first side 14 and the second side 15, are welded to the inner wall of the housing 1, respectively, and the curved side 17 is also welded to the inner wall of the housing 1. A rectangular plate 11 of one of the partitions 10 extends from the first port 4 into the housing 1, the partition 10 and the inner wall of the housing 1 opposite the partition 10 together defining a first chamber 6 closed at one end and open at the other end. A rectangular plate 11 of a further partition 10 extends from the second port 5 into the housing 1, the partition 10 and the inner wall of the housing 1 opposite the partition 10 together defining a second chamber 7 closed at one end and open at the other. The inclined plates 12 of the two separators 10 extend in opposite directions, and a third chamber 8 is formed between the two separators 10 to extend through the first port 4 and the second port 5.

The first connecting pipe 2 and the second connecting pipe 3 are used for connecting a water path. Referring to fig. 1, a first connection pipe 2 is disposed on an outer wall of a housing 1 and communicates with a first chamber 6, and a second connection pipe 3 is disposed on an outer wall of the housing 1 and communicates with a second chamber 7.
