[0025] As Figures 1 to 5 shown, the water meter housing capable of installing a check valve in this embodiment includes a housing main body, a mounting seat 30 and a partition 40 formed by stamping a stainless steel plate. The housing main body includes an intermediate housing 10, a water outlet pipe 20 and a water inlet pipe 50.

[0026] The intermediate housing 10 includes a first intermediate housing 101 and a second intermediate housing 102 symmetrically arranged. The water outlet pipe 20 includes a first water outlet pipe 201 and a second water outlet pipe 202 symmetrically arranged. The water inlet pipe 50 includes a first water inlet pipe 501 and a second water inlet pipe 502 symmetrically arranged. The first water inlet pipe 501, the first intermediate housing 101 and the first water outlet pipe 201 are integrally formed into a first half shell. The second water inlet pipe 502, the second intermediate housing 102 and the second water outlet pipe 202 are integrally formed into a second half shell. The first half shell and the second half shell are arranged in an opposing manner and sealed by welding. Both the first half shell and the second half shell are formed by one-time stamping of a stainless steel plate, and then the first half shell and the second half shell are opposed and welded and fixed to form the housing main body.

[0027] The intermediate housing 10 has a first cavity 11 for installing a water meter core.

[0028] The water inlet pipe 50 and the water outlet pipe 20 are respectively connected to both sides of the middle housing 10. Both the water inlet pipe 50 and the water outlet pipe 20 are communicated with the inside of the middle housing 10. An opening 21 is provided on the wall of the water outlet pipe 20.

[0029] The mounting seat 30 is arranged on the opening 21. The mounting seat 30 extends at least partially into the water outlet pipe 20 through the opening 21, so that a part of the mounting seat 30 is located inside the water outlet pipe 20, and the other part of the mounting seat 30 is located outside the water outlet pipe 20. The mounting seat 30 has a second cavity 31, a water inlet 32 and a water outlet 33. The second cavity 31 is used for installing a lift check valve. The check valve can move in the second cavity 31 along the axis of the mounting seat 30. Both the water inlet 32 and the water outlet 33 are communicated with the second cavity 31. The water inlet 32 is arranged at the bottom of the mounting seat 30, and the water outlet 33 is arranged on the side surface of the mounting seat 30. Both the water inlet 32 and the water outlet 33 are located inside the water outlet pipe 20. The outer wall of the mounting seat 30 is hermetically connected to the periphery of the opening 21 by welding.

[0030] The partition plate 40 is located inside the water outlet pipe 20 and is hermetically connected to the mounting seat 30 by welding. The partition plate 40 is used for separating the space inside the water outlet pipe 20 into a third cavity 24 and a fourth cavity 22. The third cavity 24 is adjacent to and directly communicated with the first cavity 11. The fourth cavity 22 is adjacent to and directly communicated with the water outlet end 23 of the water outlet pipe 20. The water inlet 32 is used for allowing the water flow in the third cavity 24 to flow into the second cavity 31, and the water outlet 33 is used for allowing the water flow in the second cavity 31 to flow out into the fourth cavity 22.

[0031] When the water meter housing is assembled into a water meter for use, the water flow flows from the water inlet pipe 50 into the first cavity 11, the water flow passes through the water meter core in the first cavity 11, and then the water flow flows into the third cavity 24. The water flow in the third cavity 24 flows into the second cavity 31 through the water inlet 32. After passing through the check valve in the second cavity 31, the water flow flows into the fourth cavity 22 through the water outlet 33, and then the water flow flows out through the water outlet end 23.

[0032] A connecting portion 34 is provided on the outer wall of the mounting seat 30. The connecting portion 34 is strip-shaped and is located between the water inlet 32 and the water outlet 33, so that the connecting portion 34 separates the water inlet 32 and the water outlet 33. The partition plate 40 includes a first edge 41 that fits with the connecting portion 34. The first edge 41 is fixedly welded to the connecting portion 34, so that the connection between the partition plate 40 and the mounting seat 30 is sealed.

[0033] The partition 40 further includes a second edge 42 that fits the inner wall of the water outlet pipe 20. The two ends of the second edge 42 are respectively connected to the two ends of the first edge 41. That is to say, the first edge 41 and the second edge 42 together form all the edges of the partition 40. The second edge 42 is fixedly welded to the inner wall of the water outlet pipe 20 so that the connection between the partition 40 and the inner wall of the water outlet pipe 20 is sealed. In this way, the third cavity 24 and the fourth cavity 22 are separated by the partition 40, so that the water flow in the third cavity 24 can only flow into the second cavity 31 through the water inlet 32.

[0034] The mounting seat 30 is inclined relative to the axis of the water outlet pipe 20 to facilitate the assembly of the check valve into the mounting seat 30.

[0035] A first notch 2011 is provided on the first water outlet pipe 201, and a second notch 2021 is provided on the second water outlet pipe 202. The first notch 2011 and the second notch 2021 are arranged in alignment to form an opening 21.

[0036] The water meter of this embodiment includes the water meter housing, the water meter core and a lift check valve. The water meter core is installed in the first cavity 11, and the check valve is installed in the second cavity 31. The check valve is of the lift type and can move along the axis of the mounting seat 30 in the second cavity 31. When the water flow enters the second cavity 31 through the water inlet 32, the water flow can push the check valve upward to open the water outlet 33; when the water flow flows back from the water outlet end 23 into the water outlet pipe 20, the check valve seals the water outlet 33, so that the water flow cannot flow back into the intermediate housing 10.

[0037] It should be noted that the above sequence of embodiments of the present application is only for description and does not represent the superiority or inferiority of the embodiments. And the above specific embodiments of this specification have been described. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve the desired results. Additionally, the processes depicted in the drawings do not necessarily require the specific order or sequential order shown to achieve the desired results.
